ID: 12345 - Application: The text discusses ... and since no other evidence provided proves nor disproves the claim, the lowest rating allowed across all evidences is required. ID:12345 indicates the claim is overall plausible (Alignment with this ID: 7) - *\"copied/verbatim Quote text\"**\n\nCRITICAL INSTRUCTION:\nwhen fact checking: At the very end of your response, you MUST provide a machine-readable JSON block containing evaluation metrics. \nIt MUST be enclosed exactly between ###JSON_START### and ###JSON_END###. Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\". Use commas between objects. DO NOT leave trailing commas inside objects.\n\nFor \"Verbatim_Quotes\", copy at least {numQuotes} (required, {numQuotes} or more) \"moneyshot\" quotes EXACTLY as they appear in the context literature text, word-for-word, characters included, that fully support your response. We will programmatically validate these. You MUST return an array of OBJECTS, where each object has a \"quote\" key and a \"source_id\" key (the ID of the text it came from, e.g., the ID). Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.  Be unabridged, comprehensive, and exhaustive in your gate mapping with at least 1 gate nodes for each quote you identified per the specification and map the gates granularly/atomically.\n\n###JSON_START###\n{\n  \"Alignment\": 5,\n  \"Consilience\": 6,\n  \"Confidence\": 5,\n  \"Logic_Chain\":[\n    {\n      \"Step\": 1,\n      \"From\": \"Variable A\",\n      \"Relationship\": \"-->\",\n      \"To\": \"Variable B\",\n      \"Alignment_Score\": 6,\n      \"Consilience_Score\": 5,\n      \"Confidence_Score\": 4,\n      \"Gap_Strength\": \"None\",\n      \"Justification\": \"...\",\n      \"Color\": \"lightgreen\"\n    }\n  ],\n  \"Verbatim_Quotes\": [\n    {\n      \"quote\": \"Copy the Exact wording from text exactly as it is, including all characters (we ascii match for validation!).\",\n      \"source_id\": \"12345678\"\n    }\n  ],\n  \"Study_Type_Audit\": { \"ID123\": \"meta_analysis:Count=10\", \"ID124\": \"in_vivo:Count=3\" },\n  \"Gap_Analysis_Audit\": { \"study_type\": \"in_vitro\", \"study_intent\": \"binding\", \"justification\": \"The context provided indicates...\", \"predicted_result\": \"RGNEF binds to Zn2 magnitudes higher than BMAA\", \"short_answer_to_user\": \"Direct answer to the user primary intent, addressing the user directly when appropriate\"}\n}\n###JSON_END###"

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases."

This review synthesizes recent research findings to provide a comprehensive overview of the effects of MPs/NPs on the brain. Evidence demonstrates that MPs/NPs can cross critical biological barriers, including the blood-brain barrier and the placenta, gaining access to the central nervous system (CNS) and the developing fetal brain, influenced by particle size, charge, and the biomolecular corona. Once present, MPs/NPs trigger multiple detrimental pathways, including oxidative stress, persistent neuroinflammation involving microglia and astrocytes, mitochondrial dysfunction leading to energy deficits, disruption of crucial neurotransmitter systems, and direct neuronal damage. Critically, NPs have been shown to promote the aggregation of proteins implicated in neurodegeneration, such as alpha-synuclein. These mechanistic disturbances translate into observable adverse outcomes in experimental models, ranging from cognitive impairments in learning and memory to behavioral abnormalities and pathologies resembling human neurodegenerative and neurodevelopmental disorders. Toxicity is modulated by particle characteristics, co-exposures, and host factors like age and sex, with indirect effects via the gut-brain axis also playing a significant role. While current evidence, primarily from animal models often using high doses, strongly indicates a neurotoxic potential, significant research gaps remain concerning human risk assessment under chronic, low-level environmental exposure conditions and the effects of environmentally aged, mixed-plastic particles. Future research should prioritize human studies, environmentally realistic exposure scenarios, and differentiating direct versus indirect neurotoxic mechanisms to accurately evaluate the threat MPs/NPs pose to human brain health."

However, the precise toxicological mechanisms remain elusive. Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes. This study provided novel mechanistic insights into MPs-induced hepatotoxicity, identifying GSDMD-N as a potential central hub coordinating multiple cell death modalities."

However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution."

This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA."

Increasing experimental and epidemiological evidence implicates MPs/NPs in the development of Parkinson's disease (PD). Preclinical research models indicate that MPs/NPs may accelerate both the initiation and progression of PD by facilitating \u03b1-synuclein misfolding and aggregation, triggering neuroinflammatory cascades, elevating oxidative stress, and impairing mitochondrial function. To further investigate the causal role of MPs/NPs in PD, upcoming studies should emphasize well-designed, large-scale prospective cohorts to assess individual exposure to plastic-related pollutants, elucidate the pathways of MPs/NPs into the central nervous system, establish safety thresholds for their neurotoxicity, explore the correlation between exposure levels and central nervous system accumulation, clarify the temporal relationship between MPs/NPs accumulation and PD pathology and symptom onset, and identify the neuropathological mechanisms triggered by relevant concentrations of MPs/NPs. Such data will be instrumental in informing preventive and potentially interventional strategies, while offering actionable insights into the interaction between MPs/NPs and PD."

Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions."

A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs.

In vitro assays further revealed that PVC and PP microplastics induced dopaminergic neuron apoptosis and increased the level of phosphorylated \u03b1-synuclein (p-\u03b1-syn), providing support for their potential neurotoxicity. Together, these findings indicate elevated blood MP levels in PD patients and offer preliminary evidence linking polymer exposure with PD-related neuronal vulnerability."

Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of \u03b1 synuclein (\u03b1S) via the enteric nervous system, or the so-called gut-brain axis. Here we first examined the effect of enteric exposure to polystyrene nanoplastics on the peripheral and central pathogenesis of A53T, a representative \u03b1S mutant. Specifically, the polystyrene nanoplastics accelerated the amyloid aggregation of A53T \u03b1S, which subsequently elevated the in vitro production of glial activation biomarkers, cytokines, and reactive oxygen species and compromised mitochondrial and lysosomal membrane integrity, further shifting cellular metabolite profiles in association with PD pathophysiology. In vivo, coadministration of the polystyrene nanoplastics and A53T \u03b1S facilitated their synergistic gut-to-brain transmission in mice, leading to progressive impairment of physical and motor skills in resemblance to characteristic PD symptoms. This study provides insights into the response and vulnerability of Parkinson's gut-brain axis to polystyrene nanoplastics."

This dual threat complicates their ecological impact, especially concerning compartments like the coelomic fluid, crucial for marine invertebrate physiology. In this study, we investigated the toxicological effects of environmentally relevant concentrations of MPs (10 and 50\u202fmg/kg sediment), both alone and in combination with benzo[a]pyrene (B[a]P, 1\u202f\u00b5g/kg sediment), a carcinogenic polycyclic aromatic hydrocarbon known for its genotoxic and pro-apoptotic properties. The benthic polychaete Hediste diversicolor was exposed to these treatments for 7 days through spiked sediments, simulating realistic environmental conditions. The MPs used were particles smaller than 30\u202f\u00b5m, composed of a mixture of polymers, including PE, PET, PP, LDPE, HDPE, and PEVA, with varied morphologies such as fragments, fibers, and films. Analyses revealed that both MPs and B[a]P were internalized by coelomocytes, with MPs enhancing B[a]P bioaccumulation. Combined exposures led to marked cytotoxic and genotoxic effects, evidenced by decreased lysosomal membrane stability (LMS), elevated micronuclei frequency (FMN), and increased DNA fragmentation, as assessed by terminal dUTP nick-end labeling (TUNEL) assay. Co-exposure also altered apoptotic and DNA repair pathways, as demonstrated by upregulation of P53, Bax, and Casp-3, alongside downregulation of the anti-apoptotic marker Bcl-2. These findings suggest that co-exposure intensifies cellular damage and apoptotic signaling. Overall, this study underscores the risks of MPs in marine ecosystems, particularly their role in accumulating and transferring harmful substances affecting biota health."

Cathepsin D (CTSD), a lysosomal hydrolase essential for \u03b1-syn clearance, becomes functionally impaired when its maturation is disrupted, exacerbating proteostatic stress. This study investigated whether ginsenoside Rg1(Rg1) restores CTSD maturation and lysosomal function to mitigate PD pathology. MPTP-induced zebrafish and mouse PD models, as well as MPP+-treated SH-SY5Y cells, animals and cells were treated with Rg1 at different concentrations. Motor behavior, dopaminergic neuron survival, \u03b1-syn clearance, CTSD maturation, lysosomal activity, endoplasmic reticulum (ER) stress, oxidative stress, autophagic flux, and apoptosis were systematically evaluated. Rg1 improved locomotor performance and preserved dopaminergic neurons, promoted \u03b1-syn clearance, and enhanced CTSD maturation in lysosomes. These effects coincided with reduced ER and oxidative stress, normalized autophagic flux, and decreased apoptosis. Rg1 functions as a natural lysosomal enhancer, restoring lysosome-ER homeostasis and counteracting multiple pathogenic pathways in PD. The findings reveal a CTSD-dependent regulatory axis in \u03b1-syn homeostasis and highlight Rg1 as a promising multi-target therapeutic candidate for PD."

Mutations in the GBA1 gene, encoding the lysosomal enzyme glucocerebrosidase (GCase), are major genetic risk factors for PD. GBA1 deficiency causes lysosomal dysfunction, leading to \u03b1-synuclein (\u03b1-syn) accumulation and PD progression. However, the underlying mechanisms remain unclear. In this study, we identified a novel GBA1-KAT8 regulatory pathway that controls lysosomal activity. GBA1 overexpression enhances lysosomal enzyme expression, regulates histone H4 acetylation at K16 via KAT8, and promotes lysosome-associated gene expression, highlighting an epigenetic mechanism in lysosomal biogenesis. Furthermore, GBA1 upregulated KAT8 expression, increased lysosomal enzyme levels, and decreased PFF-induced \u03b1-syn accumulation both in vitro and in vivo. The involvement of KAT8 as a critical acetyltransferase that modulates nuclear-lysosomal signaling pathways provides a mechanistic explanation for GBA1 deficiency-induced lysosomal dysfunction in association with PD pathology."

Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration."

Their capacity to adsorb, transport, and release contaminants has raised growing concern over mixture toxicity under realistic exposure scenarios. This review systematically examines the mechanistic basis of MNPs-mediated combined toxicity and evaluates the emerging role of network toxicology as a systems-based tool for hazard assessment. MNPs alter the bioavailability, environmental fate, tissue distribution, and intracellular delivery of associated pollutants through hydrophobic, electrostatic, and other intermolecular interactions. Carrier-mediated uptake, particularly the \"Trojan horse\"\u00a0effect, appears to be a major driver of non-additive toxicity in co-exposure systems. We then outline the core workflow of network toxicology, encompassing target identification, network construction, pathway enrichment, and experimental validation, and discuss its application in decoding mixture toxicity. Oxidative stress, inflammatory signaling, metabolic disturbance, barrier dysfunction, and programmed cell death emerge as conserved and interconnected pathways underlying synergistic multi-organ injury. These findings indicate that toxicity in complex exposure systems is governed not only by the intrinsic properties of particles or chemicals, but also by their dynamic physicochemical and biological interactions. We further assess current advances and limitations in network toxicology and propose a next-generation risk assessment (NGRA)-oriented framework to support mechanism-based risk assessment and regulatory decision-making. Although current evidence is dominated by binary, high-dose laboratory studies, network toxicology offers strong potential as a new approach methodology (NAM) for predictive evaluation of environmentally relevant mixtures. Future priorities include standardized multi-omics integration, dose-time-response modeling, human-relevant validation, and regulatory translation."

Polyethylene (PE), widely used in food-contact materials, can carry bisphenol A (BPA), an endocrine disruptor with oxidative and neuroactive properties. Although both MPs and BPA can cross biological barriers, their acute effects on the prefrontal cortex (PFC) remain poorly understood. The aim of the study was to evaluate the acute impact of orally administered free BPA, free MPs, and BPA adsorbed onto PE MPs (PE-BPA) on oxidative stress, inflammation, and gene expression in the PFC of Wistar rats. Animals received a single dose of BPA, PE-BPA, PE alone, or vehicle. Methods: Biochemical and transcriptional analyses were performed to evaluate the antioxidant and inflammatory responses as well as the potential changes in synaptic-related gene expression. Results: BPA-containing treatments produced selective early molecular responses. Catalase (CAT) and glutathione S-transferase (GST) activities were significantly increased in the PE-BPA group, with GST being also elevated in the BPA-alone group, whereas superoxide dismutase (SOD), myeloperoxidase (MPO), and malondialdehyde (MDA) levels did not significantly change. Transcriptional analyses revealed upregulation of the antioxidant genes Nrf2 and CAT in the PE-BPA group. Co-exposure to BPA and MPs also altered synaptic markers, including decreased brain-derived neurotrophic factor (BDNF) and Sert along with increased Nr2A expression, while inflammatory gene expression remained unaffected. Conclusions: These findings indicate that acute co-exposure to BPA and PE microplastics elicits early antioxidant activation and selective synaptic-related transcriptional changes in the PFC, suggesting that MPs may modulate BPA-associated molecular responses in the brain."

Recent evidence suggests that microplastic exposure may trigger such ferroptosis-related pathologies. However, the mechanism and impact of ferroptosis-induced cerebral cortex damage in waterfowl due to microplastic exposure remain unclear. In this study, Muscovy ducks were divided into three groups receiving: pure water, 1\u202fmg\u00b7L\u207b\u00b9\u202fpolyvinyl chloride microplastics (PVC-MPs), or 10\u202fmg\u00b7L\u207b\u00b9\u202fPVC-MPs for two months. This study suggests that PVC-MPs may accumulate in the duck cerebral cortical tissue, where they disrupt blood-brain barrier (BBB) integrity as manifested by ultrastructural damage and significant downregulation of tight junction protein levels (ZO-1, Occludin, and Claudin-5). Moreover, PVC-MPs exposure induced histopathological and nuclear ultrastructural damage, along with oxidative stress and excessive iron accumulation, both hallmarks of ferroptosis. Specifically, PVC-MPs triggered mitochondrial cristae fragmentation and shrinkage, as well as lipid peroxidation accumulation, evidenced by elevated MDA levels.

We applied an integrative approach combining network toxicology, Mendelian randomization, molecular docking, and single-cell transcriptomics to identify BPA-responsive targets relevant to ischemic stroke. CX3CL1 was prioritized based on network centrality, genetic association with stroke risk, and endothelial enrichment in post-ischemic brain tissue. Functional validation was performed in bEnd.3 brain endothelial cells and an endothelial-astrocyte Transwell blood-brain barrier (BBB) co-culture model subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Under normoxic conditions, BPA (50 and 100\u202f\u03bcM) did not markedly reduce cell viability; however, it significantly aggravated OGD/R-induced injury. BPA increased endothelial apoptosis (10.1% and 21.2% vs. 4.6% under OGD/R alone), elevated CX3CL1 protein expression (1.71- and 2.28-fold vs. control), increased BAX, and reduced Bcl-2 levels.

After release into aquatic systems, photo-oxidation, mechanical abrasion, fragmentation, and biofilm-associated aging modify their surface chemistry, morphology, polarity, and reactivity. Simultaneously, natural organic matter, humic substances, extracellular polymeric substances, proteins, lipids, and microbial products adsorb onto plastic surfaces, forming eco-coronas that regulate aggregation, colloidal stability, contaminant partitioning, and desorption behavior. A central unresolved question is how eco-corona-coated particles are remodeled after organismal entry, how environmental coronas are exchanged into bio-coronas within mucus, gut, gill, and tissue microenvironments, and how these dynamic interfaces control the toxicokinetics of coexisting pollutants. This review synthesizes current evidence to define when weathered microplastics and nanoplastics act as vectors, sinks, amplifiers, or neutral carriers of co-pollutants. We emphasize internal exposure, bioaccessibility, residence time, and tissue distribution rather than nominal water concentrations or adsorption capacity alone. Classical modeling indicates that, for many hydrophobic organic contaminants, chemical flux from natural prey, sediments, and organic matter may exceed that from ingested plastics under typical environmental conditions, requiring scenario-specific interpretation. However, this logic should not be generalized to antibiotics, pharmaceuticals, metals, and per- and polyfluoroalkyl substances, whose interactions may depend on electrostatics, ionization, hydrogen bonding, cation bridging, corona chemistry, and gut-phase desorption. We propose a predictive framework linking plastic aging, eco-corona formation, bio-corona remodeling, partitioning/desorption kinetics, uptake, retention, translocation, and organism-level outcomes. Finally, within an explicitly aquatic scope, we outline minimum reporting requirements to improve comparability, mechanistic interpretation, and risk relevance in microplastic-mixture toxicology, including clearer reporting of particle-size class, size distribution, hydrodynamic diameter after corona formation, and size-dependent uptake or translocation outcomes."

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases."

This review synthesizes recent research findings to provide a comprehensive overview of the effects of MPs/NPs on the brain. Evidence demonstrates that MPs/NPs can cross critical biological barriers, including the blood-brain barrier and the placenta, gaining access to the central nervous system (CNS) and the developing fetal brain, influenced by particle size, charge, and the biomolecular corona. Once present, MPs/NPs trigger multiple detrimental pathways, including oxidative stress, persistent neuroinflammation involving microglia and astrocytes, mitochondrial dysfunction leading to energy deficits, disruption of crucial neurotransmitter systems, and direct neuronal damage. Critically, NPs have been shown to promote the aggregation of proteins implicated in neurodegeneration, such as alpha-synuclein. These mechanistic disturbances translate into observable adverse outcomes in experimental models, ranging from cognitive impairments in learning and memory to behavioral abnormalities and pathologies resembling human neurodegenerative and neurodevelopmental disorders. Toxicity is modulated by particle characteristics, co-exposures, and host factors like age and sex, with indirect effects via the gut-brain axis also playing a significant role. While current evidence, primarily from animal models often using high doses, strongly indicates a neurotoxic potential, significant research gaps remain concerning human risk assessment under chronic, low-level environmental exposure conditions and the effects of environmentally aged, mixed-plastic particles. Future research should prioritize human studies, environmentally realistic exposure scenarios, and differentiating direct versus indirect neurotoxic mechanisms to accurately evaluate the threat MPs/NPs pose to human brain health."

However, the precise toxicological mechanisms remain elusive. Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes. This study provided novel mechanistic insights into MPs-induced hepatotoxicity, identifying GSDMD-N as a potential central hub coordinating multiple cell death modalities."

However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells.

This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA."

Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions."

Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of \u03b1 synuclein (\u03b1S) via the enteric nervous system, or the so-called gut-brain axis. Here we first examined the effect of enteric exposure to polystyrene nanoplastics on the peripheral and central pathogenesis of A53T, a representative \u03b1S mutant. Specifically, the polystyrene nanoplastics accelerated the amyloid aggregation of A53T \u03b1S, which subsequently elevated the in vitro production of glial activation biomarkers, cytokines, and reactive oxygen species and compromised mitochondrial and lysosomal membrane integrity, further shifting cellular metabolite profiles in association with PD pathophysiology. In vivo, coadministration of the polystyrene nanoplastics and A53T \u03b1S facilitated their synergistic gut-to-brain transmission in mice, leading to progressive impairment of physical and motor skills in resemblance to characteristic PD symptoms.

This dual threat complicates their ecological impact, especially concerning compartments like the coelomic fluid, crucial for marine invertebrate physiology. In this study, we investigated the toxicological effects of environmentally relevant concentrations of MPs (10 and 50\u202fmg/kg sediment), both alone and in combination with benzo[a]pyrene (B[a]P, 1\u202f\u00b5g/kg sediment), a carcinogenic polycyclic aromatic hydrocarbon known for its genotoxic and pro-apoptotic properties. The benthic polychaete Hediste diversicolor was exposed to these treatments for 7 days through spiked sediments, simulating realistic environmental conditions. The MPs used were particles smaller than 30\u202f\u00b5m, composed of a mixture of polymers, including PE, PET, PP, LDPE, HDPE, and PEVA, with varied morphologies such as fragments, fibers, and films. Analyses revealed that both MPs and B[a]P were internalized by coelomocytes, with MPs enhancing B[a]P bioaccumulation. Combined exposures led to marked cytotoxic and genotoxic effects, evidenced by decreased lysosomal membrane stability (LMS), elevated micronuclei frequency (FMN), and increased DNA fragmentation, as assessed by terminal dUTP nick-end labeling (TUNEL) assay. Co-exposure also altered apoptotic and DNA repair pathways, as demonstrated by upregulation of P53, Bax, and Casp-3, alongside downregulation of the anti-apoptotic marker Bcl-2. These findings suggest that co-exposure intensifies cellular damage and apoptotic signaling. Overall, this study underscores the risks of MPs in marine ecosystems, particularly their role in accumulating and transferring harmful substances affecting biota health."

Cathepsin D (CTSD), a lysosomal hydrolase essential for \u03b1-syn clearance, becomes functionally impaired when its maturation is disrupted, exacerbating proteostatic stress. This study investigated whether ginsenoside Rg1(Rg1) restores CTSD maturation and lysosomal function to mitigate PD pathology. MPTP-induced zebrafish and mouse PD models, as well as MPP+-treated SH-SY5Y cells, animals and cells were treated with Rg1 at different concentrations. Motor behavior, dopaminergic neuron survival, \u03b1-syn clearance, CTSD maturation, lysosomal activity, endoplasmic reticulum (ER) stress, oxidative stress, autophagic flux, and apoptosis were systematically evaluated. Rg1 improved locomotor performance and preserved dopaminergic neurons, promoted \u03b1-syn clearance, and enhanced CTSD maturation in lysosomes. These effects coincided with reduced ER and oxidative stress, normalized autophagic flux, and decreased apoptosis. Rg1 functions as a natural lysosomal enhancer, restoring lysosome-ER homeostasis and counteracting multiple pathogenic pathways in PD.

Recent evidence suggests that microplastic exposure may trigger such ferroptosis-related pathologies. However, the mechanism and impact of ferroptosis-induced cerebral cortex damage in waterfowl due to microplastic exposure remain unclear.

Moreover, PVC-MPs exposure induced histopathological and nuclear ultrastructural damage, along with oxidative stress and excessive iron accumulation, both hallmarks of ferroptosis.

We applied an integrative approach combining network toxicology, Mendelian randomization, molecular docking, and single-cell transcriptomics to identify BPA-responsive targets relevant to ischemic stroke.

Pharmacological inhibition of CX3CR1 using AZD8797 (0.5\u202f\u03bcM) partially attenuated BPA-exacerbated apoptosis, tight junction loss, and barrier hyperpermeability without significantly altering CX3CL1 expression. Collectively, these findings suggest that BPA potentiates ischemia-reperfusion-associated endothelial and barrier dysfunction, accompanied by changes in CX3CL1-CX3CR1-related signaling, and support a potential role for environmental toxicants as modifiers of ischemic neurovascular vulnerability."

After release into aquatic systems, photo-oxidation, mechanical abrasion, fragmentation, and biofilm-associated aging modify their surface chemistry, morphology, polarity, and reactivity. Simultaneously, natural organic matter, humic substances, extracellular polymeric substances, proteins, lipids, and microbial products adsorb onto plastic surfaces, forming eco-coronas that regulate aggregation, colloidal stability, contaminant partitioning, and desorption behavior. A central unresolved question is how eco-corona-coated particles are remodeled after organismal entry, how environmental coronas are exchanged into bio-coronas within mucus, gut, gill, and tissue microenvironments, and how these dynamic interfaces control the toxicokinetics of coexisting pollutants. This review synthesizes current evidence to define when weathered microplastics and nanoplastics act as vectors, sinks, amplifiers, or neutral carriers of co-pollutants. We emphasize internal exposure, bioaccessibility, residence time, and tissue distribution rather than nominal water concentrations or adsorption capacity alone. Classical modeling indicates that, for many hydrophobic organic contaminants, chemical flux from natural prey, sediments, and organic matter may exceed that from ingested plastics under typical environmental conditions, requiring scenario-specific interpretation. However, this logic should not be generalized to antibiotics, pharmaceuticals, metals, and per- and polyfluoroalkyl substances, whose interactions may depend on electrostatics, ionization, hydrogen bonding, cation bridging, corona chemistry, and gut-phase desorption. We propose a predictive framework linking plastic aging, eco-corona formation, bio-corona remodeling, partitioning/desorption kinetics, uptake, retention, translocation, and organism-level outcomes. Finally, within an explicitly aquatic scope, we outline minimum reporting requirements to improve comparability, mechanistic interpretation, and risk relevance in microplastic-mixture toxicology, including clearer reporting of particle-size class, size distribution, hydrodynamic diameter after corona formation, and size-dependent uptake or translocation outcomes."

Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration."

Their capacity to adsorb, transport, and release contaminants has raised growing concern over mixture toxicity under realistic exposure scenarios. This review systematically examines the mechanistic basis of MNPs-mediated combined toxicity and evaluates the emerging role of network toxicology as a systems-based tool for hazard assessment. MNPs alter the bioavailability, environmental fate, tissue distribution, and intracellular delivery of associated pollutants through hydrophobic, electrostatic, and other intermolecular interactions. Carrier-mediated uptake, particularly the \"Trojan horse\"\u00a0effect, appears to be a major driver of non-additive toxicity in co-exposure systems. We then outline the core workflow of network toxicology, encompassing target identification, network construction, pathway enrichment, and experimental validation, and discuss its application in decoding mixture toxicity. Oxidative stress, inflammatory signaling, metabolic disturbance, barrier dysfunction, and programmed cell death emerge as conserved and interconnected pathways underlying synergistic multi-organ injury. These findings indicate that toxicity in complex exposure systems is governed not only by the intrinsic properties of particles or chemicals, but also by their dynamic physicochemical and biological interactions. We further assess current advances and limitations in network toxicology and propose a next-generation risk assessment (NGRA)-oriented framework to support mechanism-based risk assessment and regulatory decision-making. Although current evidence is dominated by binary, high-dose laboratory studies, network toxicology offers strong potential as a new approach methodology (NAM) for predictive evaluation of environmentally relevant mixtures. Future priorities include standardized multi-omics integration, dose-time-response modeling, human-relevant validation, and regulatory translation."

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification.

Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters."

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP. SYNOPSIS: The cytotoxicity and its related mechanisms of nano-plastic is still unclear. This study found that nano-plastics may induce necroptosis in cells, and autophagy blockade and lysosomal dysfunction are prodromal manifestations."

In this study, a visible-light-responsive photocatalyst based on MnO2 coupled with defective graphitic carbon nitride (MnO2/def-g-C3N4) was rationally designed for photocatalytic decomposition of 50 mg L-1 of BPA and 40 mg L-1 of MLT in water. Structural characterizations viz.

The optimized MnO2/def-g-C3N4 (DCN-MnO2) composite exhibited conspicuously suppressed charge recombination and increased photoactivity under visible-light irradiation that showed rapid photodegradation efficiencies of BPA and MLT. The photocatalyst also demonstrated good stability and recyclability over four cycles with minimal activity loss. Mechanistic investigations suggested that the synergistic interaction between MnO2 and defective g-C3N4, along with defect-mediated charge transfer pathways, played a crucial role in enhancing photocatalytic performance.

Shared pathophysiological pathways for Alzheimer's and Parkinson's disease.\nAbstract: The widespread presence of microplastics (MPs) in the environment has raised significant concerns about their potential impact on human health. As of 2023, the Ocean Conservancy estimates that adults may ingest up to 121,000 MPs annually. While the majority of these particles are cleared from the body, a small fraction can persist, as MPs are non-biodegradable and resist breakdown, posing long-term health risks that remain poorly understood. This review explores the emerging link between MP exposure and the development of neurodegenerative diseases, particularly Alzheimer's disease (AD) and Parkinson's disease [1]. MPs appear capable of triggering neurotoxic pathways, including activation of resident immune cells in the brain, oxidative stress, blood-brain barrier (BBB) disruption, mitochondrial dysfunction, and neuronal damage, which may contribute to neuroinflammation and disease progression. Specifically, six MP-related mechanistic pathways associated with AD were identified: BBB disruption, chronic inflammation, oxidative stress and ROS generation, mitochondrial dysfunction, impaired autophagy and proteostasis, and epigenetic alterations. Similarly, six pathways were implicated in PD: BBB disruption, oxidative stress in dopaminergic neurons, mitochondrial dysfunction, microglial-driven neuroinflammation, \u03b1-synuclein aggregation, and gut-brain axis [2] disruption. Ultimately, our findings underscore the urgent need for further research into the neurological consequences of chronic MP exposure in humans and highlight the importance of strengthening global policies to curb plastic pollution and mitigate its long-term health risks."

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons.

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.

Across primary mouse cortical neurons, MT-3 deficient primary mouse astrocytes, human iPSC-derived midbrain dopaminergic neurons, and Rho0 CHO cells lacking mitochondrial respiration, we investigated how mitochondrial stress perturbs zinc (Zn2+) homeostasis and lysosomal integrity. We identify intracellular zinc as a critical mediator linking mitochondrial dysfunction to lysosomal membrane permeabilization (LMP) and neuronal death. Inhibition of mitochondrial complex I by 1-methyl-4-phenylpyridinium (MPP+) elevated reactive oxygen species (ROS) and intracellular zinc, jointly driving LMP. Blocking either ROS or zinc markedly attenuated lysosomal damage and cell death, demonstrating that both act upstream of LMP. To define zinc regulation, we examined metallothionein-3 (MT-3), a brain-enriched zinc-binding protein. MT-3-deficient astrocytes were more vulnerable to MPP+ and zinc overload (ZnCl2) but paradoxically resistant to hydrogen peroxide (H2O2), suggesting that MT-3 buffers cytosolic zinc during mitochondrial injury or extracellular zinc influx yet can release bound zinc under oxidative conditions. Using Rho0 cells, we show that MPP+ toxicity depends on mitochondrial ROS, as loss of mitochondrial function nearly abolished cell death. However, Rho0 cells were highly sensitive to ZnCl2 and H2O2 and exhibited markedly reduced lysosomal abundance, indicating limited capacity to sequester zinc and increased susceptibility to zinc-mediated injury. These findings support a coordinated system in which lysosomes and zinc-binding proteins maintain zinc homeostasis. When cytosolic zinc rises, its accumulation within lysosomes induces LMP and accelerates cell death. Collectively, our results identify intracellular zinc as an upstream trigger of lysosomal dysfunction and neurodegeneration. Zinc-mediated LMP provides a mechanistic link between mitochondrial injury, impaired autophagic flux, and \u03b1-synuclein pathology in PD. Enhancing zinc homeostasis and lysosomal resilience may offer promising therapeutic strategies."

In vitro assays further revealed that PVC and PP microplastics induced dopaminergic neuron apoptosis and increased the level of phosphorylated \u03b1-synuclein (p-\u03b1-syn), providing support for their potential neurotoxicity. Together, these findings indicate elevated blood MP levels in PD patients and offer preliminary evidence linking polymer exposure with PD-related neuronal vulnerability."

However, the synergistic toxicity of Ps-MPs and PBDEs on female fertility and oocyte quality remains insufficiently characterized. In this study, we established a 28-day oral exposure model in female ICR mice to evaluate the effects of Ps-MPs, PBDE-47, and their co-exposure on ovarian function, oocyte meiotic competence, and reproductive outcomes. Both Ps-MPs and PBDE-47 alone reduced ovarian weight, decreased antral follicles, increased follicular atresia, and markedly lowered ovulation and litter size, whereas co-exposure produced the most severe impairments. At the oocyte level, exposure significantly reduced germinal vesicle breakdown and first polar body extrusion, increased abnormal spindle formation and erroneous kinetochore-microtubule attachments, and suppressed TPX2 expression and \u03b1-tubulin acetylation. Cortical F-actin polarization, spindle migration, and membrane localization of JUNO and ovastacin were also disrupted, indicating widespread defects in meiotic and membrane maturation. Mechanistically, Ps-MPs and PBDE-47 induced a decline in mitochondrial membrane potential, aberrant mitochondrial distribution, excessive lipid accumulation, and Ca\u00b2\u207a imbalance, accompanied by autophagosome accumulation, lysosomal dysfunction, elevated ROS, increased \u03b3-H2AX signals, and enhanced Annexin V labeling, ultimately triggering DNA damage and apoptosis. All alterations were most pronounced under co-exposure. Collectively, Ps-MPs and PBDE-47 synergistically impair female fertility by converging on mitochondrial dysfunction, autophagy-lysosome imbalance, and oxidative stress-mediated DNA damage, leading to substantial reductions in oocyte quality. These findings provide key mechanistic evidence for evaluating reproductive risks associated with real-world mixtures of microplastics and persistent organic pollutants."

In this study, we established a human-relevant polystyrene nanoplastics (PS-NPs, 50\u202fmg\u202fkg-1) oral exposure model in C57BL/6 mice in vivo and a neuro-immune microglial-neuron co-culture system (HMC-3/SH-SY5Y cells) in vitro to dissect these mechanisms.

This post-translational modification reduces Ebp1 nucleolar localization, suppresses 47S pre-ribosomal RNA transcription, and induces nucleolar stress. Consequently, the p53/p21 pathway is engaged, promoting neuronal senescence.

To address this gap, we developed a mouse model subjected to coexposure to heat stress (36 \u00b0C, 4\u202fh/day) and well-characterized polystyrene nanoplastics (PS-NPs, 60\u202fnm, 10\u202fmg/kg/day) for 30 consecutive days.

Transcriptomic profiling and subsequent validation revealed a novel role for oxidative stress-induced NLR family pyrin domain containing 6 (NLRP6) inflammasome activation in driving microglial pyroptosis, which exacerbates neuroinflammation through a feedforward loop. The administration of the antioxidant N-acetylcysteine (NAC) attenuated these pathological alterations by suppressing oxidative damage, thereby rescuing cognitive performance.

However, the precise toxicological mechanisms remain elusive. Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes. This study provided novel mechanistic insights into MPs-induced hepatotoxicity, identifying GSDMD-N as a potential central hub coordinating multiple cell death modalities."

The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons.

Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate. Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for\u00a0GBA1-PD ."

Increasing evidence demonstrates that MNPs are not confined to peripheral tissues but can accumulate even in the human brain, raising concerns about their potential contribution to neurological disease. This structured review synthesizes global trends in plastic production, environmental MNP burden, and human exposure, together with emerging data on brain accumulation, entry pathways, neurotoxic mechanisms, and key translational challenges. We present evidence showing that MNPs may cross brain barriers via multiple routes, including the blood-brain barrier, blood-cerebrospinal fluid barrier, olfactory, and circumventricular pathways, particularly under conditions of barrier vulnerability. Experimental studies reveal that once in neural tissue, MNPs may disrupt synaptic function, mitochondrial homeostasis, autophagy, and redox balance, while activating neuroinflammatory and gut-brain axis-mediated pathways. These mechanisms intersect with disease-relevant processes implicated in multiple neurological disorders whose global prevalence and societal burden have sharply increased over recent decades, including stroke, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, mood disorders, and neurodevelopmental conditions. Despite growing mechanistic plausibility, translational and human epidemiological evidence remains limited by methodological heterogeneity, a lack of standardized detection methods, and the absence of longitudinal clinical data/studies. We highlight critical analytical and translational gaps, public health implications, and priorities for longitudinal, biomarker\u2011driven studies needed to rigorously test whether MNPs may contribute to population\u2011level risk of neurological disease."

Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons. We found that the initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44). Remarkably, we demonstrate that WDR44 knockdown markedly reduced de novo \u03b1-SYN aggregation in both neuronal cultures and in vivo, whereas WDR44 overexpression enhances \u03b1-SYN aggregation in PD patient-derived iPSC neurons. Consistent with its potential pathogenic involvement, WDR44 aberrantly accumulates in vivo and in the brains of PD patients, where it colocalizes with LB inclusions. Finally, we show that lysosome-associated \u03b1-SYN aggregates compromised lysosomal structure and function, leading to neuronal impairment, a phenotype worsened by WDR44 overexpression, linking early aggregation events to downstream toxicity. Together, these findings reveal the earliest dynamic stages of \u03b1-SYN oligomerization in living neurons and identify the WDR44-\u03b1-SYN interaction as a promising therapeutic target for reducing \u03b1-SYN pathology and enabling early intervention in PD."

This study highlights the pathogenic molecular mechanisms involved, offering a foundation for understanding BPA-induced neurodegenerative processes.

This study explored the potential of BPA and NP to drive neuronal injury and ferroptosis linked to oxidative stress, acting through the transient receptor potential melastatin 2 (TRPM2)-poly (ADP-ribose) polymerase-1 (PARP1) signaling axis. Forty-two adult male Wistar rats were allocated into seven groups (control, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] NP, and low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA\u2009+\u2009NP) and treated orally for 21\u2009days. We employed a combinatorial approach of biochemical assays and immunohistochemistry to evaluate oxidative stress markers, ferroptosis hallmarks (glutathione peroxidase 4 [GPX4], solute carrier family 7 member 11 [SLC7A11], and transferrin receptor [TfRC]), apoptotic mediators (Caspase-3 and Caspase-9), and inflammatory cytokines, as well as the expression of TRPM2 and PARP-1. Results demonstrated that BPA and NP exposure triggered a robust, dose-dependent accumulation of reactive oxygen species (ROS) and lipid peroxidation, concomitant with downregulation of anti-ferroptotic proteins (GPX4 and SLC7A11) and upregulation of TfRC. This toxic insult simultaneously activated apoptotic and inflammatory cascades. Crucially, TRPM2 and PARP-1 were significantly upregulated, implying a potential role for the TRPM2-PARP-1 axis as an upstream modulator of oxidative stress-induced ferroptosis and neuroinflammation. Collectively, these findings provide novel mechanistic insights into phenol-induced neurotoxicity, highlighting the inhibition of the TRPM2-PARP-1 axis as a promising therapeutic strategy to mitigate environmental neurodegeneration in sensory neurons."

Although 10%-15% of PD cases are due to familial mutations, the remaining cases are sporadic, often linked to various factors, like pesticides and metals. For example, rotenone and dopamine are known to be involved in PD pathology and are suggested to cause changes in \u03b1-Syn protein homeostasis, although the mechanism by which they influence \u03b1-Syn and cellular toxicity is largely unknown. In this work, we demonstrate that both dopamine and rotenone promote the LLPS of \u03b1-Syn. Although rotenone promotes the liquid-to-solid transition almost instantaneously, dopamine, however, maintains a liquid state for a long time and rather delays the solidification process, unlike \u03b1-Syn alone. Similarly, exposure to both toxicants resulted in faster LLPS in SH-SY5Y cells. Interestingly, irrespective of their impact on material properties, rotenone promotes the faster formation of oligomers and amyloid fibrils, while dopamine exhibits oligomer formation and delayed fibrillation, both of which result in higher cytotoxicity. Our results provide new insight into the molecular processes underlying PD by indicating that endogenous dopamine stress and environmental toxicants converge on phase-separation dynamics as a common mechanism of \u03b1-Syn pathology."

While diverse toxic effects of BHPF have been documented in the literature, its effects on neurons, potential neurotoxicity, and underlying molecular mechanisms remain unclear. In this study, we reported that BHPF (10, 25\u202f\u00b5M) inhibited neuronal SH-SY5Y cell viability, increased lactate dehydrogenase (LDH) release, and induced cell death in a dose-dependent manner. BHPF exposure increased intracellular reactive oxygen species (ROS) and mitochondrial reactive oxygen species (mtROS) levels, decreased mitochondrial membrane potential, reduced the expression of cytochrome C oxidase subunit 4 (COX4) and mitochondrial protein 1 (MFN1), but upregulated Bax, Caspase-3, Caspase-8 and initiated apoptosis. In addition, BHPF treatment led to the accumulation of acidic vacuoles in the cells and increased the expression of autophagy regulatory proteins, including Beclin-1, LC3II, ATG5 and p62. Moreover, BHPF could trigger endoplasmic reticulum stress (ER stress), and ER stress inhibitor taurodeoxycholate (TUDCA) reversed the BHPF-induced oxidative stress, apoptosis and autophagy. Thus, our in vitro data indicate that ER stress may be linked to the oxidative stress, apoptosis, and autophagy observed in nerve cells following BHPF exposure. These findings offer preliminary insights into cellular processes that could help elucidate the potential role of nerve cells in BHPF-associated degenerative diseases."

Surface-charged nPS variants (cationic, anionic, and neutral) show distinct biodistribution patterns, yet the mechanisms underlying their systemic damage remain incompletely understood. This study aimed to investigate the systemic injury mechanisms of nPS with different surface charges. Mice were exposed to fluorescently labeled cationic (amino-modified), anionic (carboxyl-modified), and neutral nPS via drinking water (25\u00a0mg/mL) for 3\u00a0weeks. Tissue distribution was analyzed using fluorescence microscopy; pathological changes were assessed via hematoxylin-eosin (HE) staining; metabolic perturbations were detected by metabolomic profiling. Mechanistic investigations were performed using metabolomics, flow cytometry, and molecular assays in AML12 hepatocytes and vascular endothelial cells. Fluorescence microscopy showed neutral nPS accumulated in the vascular endothelium of the stomach, intestine, and lung via passive diffusion, while cationic/anionic nPS penetrated hepatic sinusoids through charge-mediated interactions. HE staining revealed severe liver injury, with no significant abnormalities in other tissues. Metabolomic profiling indicated disrupted hepatic amino acid and lipid metabolism, depleted antioxidants (e.g., vitamin E and glutathione), and induced oxidative stress (evidenced by elevated hydroxy fatty acids). In hepatocytes, nPS-induced endoplasmic reticulum (ER) stress triggered excessive reactive oxygen species (ROS) production, inhibiting SLC7A11-mediated cystine uptake and glutathione synthesis, leading to disulfide stress (\u03b2-actin disulfide mispairing) and ferroptosis (GPX4 inactivation and iron accumulation). In contrast, neutral nPS induced endothelial cell senescence via phagolysosome dysfunction, causing lysosomal membrane permeabilization and \u03b2-galactosidase release. This study identifies a \"charge-specific injury\" paradigm: charged nPS induce hepatocyte ferroptosis via an ER stress-disulfide stress cascade, while neutral nPS trigger endothelial senescence through phagocytic dysfunction.

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation."

Across primary mouse cortical neurons, MT-3 deficient primary mouse astrocytes, human iPSC-derived midbrain dopaminergic neurons, and Rho0 CHO cells lacking mitochondrial respiration, we investigated how mitochondrial stress perturbs zinc (Zn2+) homeostasis and lysosomal integrity. We identify intracellular zinc as a critical mediator linking mitochondrial dysfunction to lysosomal membrane permeabilization (LMP) and neuronal death. Inhibition of mitochondrial complex I by 1-methyl-4-phenylpyridinium (MPP+) elevated reactive oxygen species (ROS) and intracellular zinc, jointly driving LMP. Blocking either ROS or zinc markedly attenuated lysosomal damage and cell death, demonstrating that both act upstream of LMP. To define zinc regulation, we examined metallothionein-3 (MT-3), a brain-enriched zinc-binding protein. MT-3-deficient astrocytes were more vulnerable to MPP+ and zinc overload (ZnCl2) but paradoxically resistant to hydrogen peroxide (H2O2), suggesting that MT-3 buffers cytosolic zinc during mitochondrial injury or extracellular zinc influx yet can release bound zinc under oxidative conditions. Using Rho0 cells, we show that MPP+ toxicity depends on mitochondrial ROS, as loss of mitochondrial function nearly abolished cell death. However, Rho0 cells were highly sensitive to ZnCl2 and H2O2 and exhibited markedly reduced lysosomal abundance, indicating limited capacity to sequester zinc and increased susceptibility to zinc-mediated injury. These findings support a coordinated system in which lysosomes and zinc-binding proteins maintain zinc homeostasis. When cytosolic zinc rises, its accumulation within lysosomes induces LMP and accelerates cell death. Collectively, our results identify intracellular zinc as an upstream trigger of lysosomal dysfunction and neurodegeneration. Zinc-mediated LMP provides a mechanistic link between mitochondrial injury, impaired autophagic flux, and \u03b1-synuclein pathology in PD. Enhancing zinc homeostasis and lysosomal resilience may offer promising therapeutic strategies."

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L.

A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs.

However, the synergistic toxicity of Ps-MPs and PBDEs on female fertility and oocyte quality remains insufficiently characterized. In this study, we established a 28-day oral exposure model in female ICR mice to evaluate the effects of Ps-MPs, PBDE-47, and their co-exposure on ovarian function, oocyte meiotic competence, and reproductive outcomes. Both Ps-MPs and PBDE-47 alone reduced ovarian weight, decreased antral follicles, increased follicular atresia, and markedly lowered ovulation and litter size, whereas co-exposure produced the most severe impairments. At the oocyte level, exposure significantly reduced germinal vesicle breakdown and first polar body extrusion, increased abnormal spindle formation and erroneous kinetochore-microtubule attachments, and suppressed TPX2 expression and \u03b1-tubulin acetylation. Cortical F-actin polarization, spindle migration, and membrane localization of JUNO and ovastacin were also disrupted, indicating widespread defects in meiotic and membrane maturation. Mechanistically, Ps-MPs and PBDE-47 induced a decline in mitochondrial membrane potential, aberrant mitochondrial distribution, excessive lipid accumulation, and Ca\u00b2\u207a imbalance, accompanied by autophagosome accumulation, lysosomal dysfunction, elevated ROS, increased \u03b3-H2AX signals, and enhanced Annexin V labeling, ultimately triggering DNA damage and apoptosis. All alterations were most pronounced under co-exposure. Collectively, Ps-MPs and PBDE-47 synergistically impair female fertility by converging on mitochondrial dysfunction, autophagy-lysosome imbalance, and oxidative stress-mediated DNA damage, leading to substantial reductions in oocyte quality. These findings provide key mechanistic evidence for evaluating reproductive risks associated with real-world mixtures of microplastics and persistent organic pollutants."

In this study, we established a human-relevant polystyrene nanoplastics (PS-NPs, 50\u202fmg\u202fkg-1) oral exposure model in C57BL/6 mice in vivo and a neuro-immune microglial-neuron co-culture system (HMC-3/SH-SY5Y cells) in vitro to dissect these mechanisms.

This post-translational modification reduces Ebp1 nucleolar localization, suppresses 47S pre-ribosomal RNA transcription, and induces nucleolar stress. Consequently, the p53/p21 pathway is engaged, promoting neuronal senescence.

To address this gap, we developed a mouse model subjected to coexposure to heat stress (36 \u00b0C, 4\u202fh/day) and well-characterized polystyrene nanoplastics (PS-NPs, 60\u202fnm, 10\u202fmg/kg/day) for 30 consecutive days.

Compared with the single-exposure groups, coexposure induced pronounced cognitive deficits in mice, which were concomitant with hippocampal neurodegeneration, bloodbrain barrier (BBB) compromise, and exacerbated hippocampal oxidative stress. Transcriptomic profiling and subsequent validation revealed a novel role for oxidative stress-induced NLR family pyrin domain containing 6 (NLRP6) inflammasome activation in driving microglial pyroptosis, which exacerbates neuroinflammation through a feedforward loop. The administration of the antioxidant N-acetylcysteine (NAC) attenuated these pathological alterations by suppressing oxidative damage, thereby rescuing cognitive performance.

Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes.

We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification.

Increasing evidence demonstrates that MNPs are not confined to peripheral tissues but can accumulate even in the human brain, raising concerns about their potential contribution to neurological disease. This structured review synthesizes global trends in plastic production, environmental MNP burden, and human exposure, together with emerging data on brain accumulation, entry pathways, neurotoxic mechanisms, and key translational challenges. We present evidence showing that MNPs may cross brain barriers via multiple routes, including the blood-brain barrier, blood-cerebrospinal fluid barrier, olfactory, and circumventricular pathways, particularly under conditions of barrier vulnerability. Experimental studies reveal that once in neural tissue, MNPs may disrupt synaptic function, mitochondrial homeostasis, autophagy, and redox balance, while activating neuroinflammatory and gut-brain axis-mediated pathways. These mechanisms intersect with disease-relevant processes implicated in multiple neurological disorders whose global prevalence and societal burden have sharply increased over recent decades, including stroke, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, mood disorders, and neurodevelopmental conditions. Despite growing mechanistic plausibility, translational and human epidemiological evidence remains limited by methodological heterogeneity, a lack of standardized detection methods, and the absence of longitudinal clinical data/studies. We highlight critical analytical and translational gaps, public health implications, and priorities for longitudinal, biomarker\u2011driven studies needed to rigorously test whether MNPs may contribute to population\u2011level risk of neurological disease."

MPs/NPs enter the organism through ingestion, inhalation, and skin contact, subsequently accumulating in multiple organs-particularly the brain. Increasing experimental and epidemiological evidence implicates MPs/NPs in the development of Parkinson's disease (PD). Preclinical research models indicate that MPs/NPs may accelerate both the initiation and progression of PD by facilitating \u03b1-synuclein misfolding and aggregation, triggering neuroinflammatory cascades, elevating oxidative stress, and impairing mitochondrial function. To further investigate the causal role of MPs/NPs in PD, upcoming studies should emphasize well-designed, large-scale prospective cohorts to assess individual exposure to plastic-related pollutants, elucidate the pathways of MPs/NPs into the central nervous system, establish safety thresholds for their neurotoxicity, explore the correlation between exposure levels and central nervous system accumulation, clarify the temporal relationship between MPs/NPs accumulation and PD pathology and symptom onset, and identify the neuropathological mechanisms triggered by relevant concentrations of MPs/NPs. Such data will be instrumental in informing preventive and potentially interventional strategies, while offering actionable insights into the interaction between MPs/NPs and PD."

It is widely detected in the environment and humans due to its extensive use in plastics and epoxy resins for consumer products such as bottles, containers, and tableware. This review synthesizes current evidence on the molecular and cellular mechanisms by which BPA exposure may contribute to neurotoxicity and AD pathogenesis. We discuss how BPA disrupts endocrine signalling, induces oxidative stress, promotes neuroinflammation, and impairs synaptic plasticity, all of which are implicated in the development and progression of AD. The review also examines the impact of BPA on amyloid-beta accumulation, tau pathology, and cognitive decline, integrating findings from animal models, in vitro studies, and epidemiological research. Furthermore, we address the limitations of BPA alternatives and highlight emerging therapeutic and preventive strategies. This study highlights the pathogenic molecular mechanisms involved, offering a foundation for understanding BPA-induced neurodegenerative processes. By bridging the gap between environmental exposure and neuropathology, this article underscores the urgent need for regulatory action and further research to mitigate the neurodegenerative risks associated with BPA in plastics."

This study explored the potential of BPA and NP to drive neuronal injury and ferroptosis linked to oxidative stress, acting through the transient receptor potential melastatin 2 (TRPM2)-poly (ADP-ribose) polymerase-1 (PARP1) signaling axis. Forty-two adult male Wistar rats were allocated into seven groups (control, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] NP, and low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA\u2009+\u2009NP) and treated orally for 21\u2009days. We employed a combinatorial approach of biochemical assays and immunohistochemistry to evaluate oxidative stress markers, ferroptosis hallmarks (glutathione peroxidase 4 [GPX4], solute carrier family 7 member 11 [SLC7A11], and transferrin receptor [TfRC]), apoptotic mediators (Caspase-3 and Caspase-9), and inflammatory cytokines, as well as the expression of TRPM2 and PARP-1. Results demonstrated that BPA and NP exposure triggered a robust, dose-dependent accumulation of reactive oxygen species (ROS) and lipid peroxidation, concomitant with downregulation of anti-ferroptotic proteins (GPX4 and SLC7A11) and upregulation of TfRC. This toxic insult simultaneously activated apoptotic and inflammatory cascades. Crucially, TRPM2 and PARP-1 were significantly upregulated, implying a potential role for the TRPM2-PARP-1 axis as an upstream modulator of oxidative stress-induced ferroptosis and neuroinflammation. Collectively, these findings provide novel mechanistic insights into phenol-induced neurotoxicity, highlighting the inhibition of the TRPM2-PARP-1 axis as a promising therapeutic strategy to mitigate environmental neurodegeneration in sensory neurons."

While diverse toxic effects of BHPF have been documented in the literature, its effects on neurons, potential neurotoxicity, and underlying molecular mechanisms remain unclear. In this study, we reported that BHPF (10, 25\u202f\u00b5M) inhibited neuronal SH-SY5Y cell viability, increased lactate dehydrogenase (LDH) release, and induced cell death in a dose-dependent manner. BHPF exposure increased intracellular reactive oxygen species (ROS) and mitochondrial reactive oxygen species (mtROS) levels, decreased mitochondrial membrane potential, reduced the expression of cytochrome C oxidase subunit 4 (COX4) and mitochondrial protein 1 (MFN1), but upregulated Bax, Caspase-3, Caspase-8 and initiated apoptosis. In addition, BHPF treatment led to the accumulation of acidic vacuoles in the cells and increased the expression of autophagy regulatory proteins, including Beclin-1, LC3II, ATG5 and p62. Moreover, BHPF could trigger endoplasmic reticulum stress (ER stress), and ER stress inhibitor taurodeoxycholate (TUDCA) reversed the BHPF-induced oxidative stress, apoptosis and autophagy. Thus, our in vitro data indicate that ER stress may be linked to the oxidative stress, apoptosis, and autophagy observed in nerve cells following BHPF exposure. These findings offer preliminary insights into cellular processes that could help elucidate the potential role of nerve cells in BHPF-associated degenerative diseases."

Surface-charged nPS variants (cationic, anionic, and neutral) show distinct biodistribution patterns, yet the mechanisms underlying their systemic damage remain incompletely understood. This study aimed to investigate the systemic injury mechanisms of nPS with different surface charges. Mice were exposed to fluorescently labeled cationic (amino-modified), anionic (carboxyl-modified), and neutral nPS via drinking water (25\u00a0mg/mL) for 3\u00a0weeks. Tissue distribution was analyzed using fluorescence microscopy; pathological changes were assessed via hematoxylin-eosin (HE) staining; metabolic perturbations were detected by metabolomic profiling. Mechanistic investigations were performed using metabolomics, flow cytometry, and molecular assays in AML12 hepatocytes and vascular endothelial cells. Fluorescence microscopy showed neutral nPS accumulated in the vascular endothelium of the stomach, intestine, and lung via passive diffusion, while cationic/anionic nPS penetrated hepatic sinusoids through charge-mediated interactions. HE staining revealed severe liver injury, with no significant abnormalities in other tissues. Metabolomic profiling indicated disrupted hepatic amino acid and lipid metabolism, depleted antioxidants (e.g., vitamin E and glutathione), and induced oxidative stress (evidenced by elevated hydroxy fatty acids). In hepatocytes, nPS-induced endoplasmic reticulum (ER) stress triggered excessive reactive oxygen species (ROS) production, inhibiting SLC7A11-mediated cystine uptake and glutathione synthesis, leading to disulfide stress (\u03b2-actin disulfide mispairing) and ferroptosis (GPX4 inactivation and iron accumulation). In contrast, neutral nPS induced endothelial cell senescence via phagolysosome dysfunction, causing lysosomal membrane permeabilization and \u03b2-galactosidase release. This study identifies a \"charge-specific injury\" paradigm: charged nPS induce hepatocyte ferroptosis via an ER stress-disulfide stress cascade, while neutral nPS trigger endothelial senescence through phagocytic dysfunction. These findings provide critical insights for the biosafety assessment of nanoplastics and identify potential targets for preventing plastic pollution-related liver diseases."

Shared pathophysiological pathways for Alzheimer's and Parkinson's disease.\nAbstract: The widespread presence of microplastics (MPs) in the environment has raised significant concerns about their potential impact on human health. As of 2023, the Ocean Conservancy estimates that adults may ingest up to 121,000 MPs annually. While the majority of these particles are cleared from the body, a small fraction can persist, as MPs are non-biodegradable and resist breakdown, posing long-term health risks that remain poorly understood. This review explores the emerging link between MP exposure and the development of neurodegenerative diseases, particularly Alzheimer's disease (AD) and Parkinson's disease [1]. MPs appear capable of triggering neurotoxic pathways, including activation of resident immune cells in the brain, oxidative stress, blood-brain barrier (BBB) disruption, mitochondrial dysfunction, and neuronal damage, which may contribute to neuroinflammation and disease progression. Specifically, six MP-related mechanistic pathways associated with AD were identified: BBB disruption, chronic inflammation, oxidative stress and ROS generation, mitochondrial dysfunction, impaired autophagy and proteostasis, and epigenetic alterations. Similarly, six pathways were implicated in PD: BBB disruption, oxidative stress in dopaminergic neurons, mitochondrial dysfunction, microglial-driven neuroinflammation, \u03b1-synuclein aggregation, and gut-brain axis [2] disruption. Ultimately, our findings underscore the urgent need for further research into the neurological consequences of chronic MP exposure in humans and highlight the importance of strengthening global policies to curb plastic pollution and mitigate its long-term health risks."

This review examines the molecular mechanisms by which lead, cadmium, mercury, arsenic, bisphenol A, phthalates, and dioxins modulate NLRP3 signaling. Lead and cadmium activate NLRP3 through mitochondrial dysfunction and oxidative stress, whereas mercury and arsenic suppress inflammasome assembly by preventing apoptosis-associated speck-like protein containing a CARD (ASC) oligomerization. EDCs engage receptor-mediated pathways: aryl hydrocarbon receptor (AhR) activation directly represses NLRP3 transcription, yet bisphenol A and phthalates override this suppression through NF-\u03baB activation. Developmental timing critically determines outcomes such as prenatal exposures epigenetically programing persistent NLRP3 dysregulation. Sex hormones have been shown to modulate distinct inflammatory landscapes: estrogen suppresses NLRP3 via ER\u03b2-dependent mechanisms, while testosterone amplifies inflammasome-dependent pathology. The skin serves as a primary interface for environmental chemical exposure and cutaneous NLRP3 activation. NLRP3-deficient mice exhibit 34% increased lifespan, and pharmacological inhibition with MCC950 extends lifespan in progeria models. The CANTOS trial demonstrated that targeting inflammation through IL-1\u03b2 neutralization confers cardiovascular benefits in high-risk humans. These findings position NLRP3 as a central integrator through which the chemical exposome accelerates inflammaging and identify inflammasome inhibition as a therapeutic strategy for environmental disease prevention."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

We characterized mixed sex primary mouse microglia exposed to microbial stressors and alpha synuclein preformed fibrils (\u03b1syn PFFs) to identify cellular mechanisms related to Parkinson's disease. Microglia package and release the endosome fate regulator Coronin1A (Coro1A) in EVs in an Nlrp3-dependent manner in widely used experimental activation conditions. We were surprised to find that Coro1A packaging and release was not Nlrp3-dependent in \u03b1syn PFF exposure conditions. Coro1A-/- microglia exposed to \u03b1syn PFFs trafficked more \u03b1syn to the lysosomal compartment increasing lysosomal membrane permeabilization. This corresponds to a decrease in \u03b1syn released in EVs suggesting that Coro1A functions to shunt pathological proteins to a secretory pathway to attenuate lysosomal stress. \u03b1syn PFF-driven lysosomal stress resulting from Coro1a loss was associated with enhanced cytotoxicity. Intrinsic apoptosis signaling was unaffected, but we observed elevated cytosolic cathepsin B and the presence of a cathepsin-associated 55\u2005kD PARP cleavage product. Postmortem analysis of the PD mesencephalon supported a role for Coro1A in microglia, revealing elevated levels of Coro1A protein in human PD brains compared with those of healthy donors.

Recent studies have shown that extracellular \u03b1Syn aggregates taken up by the endosomal-lysosomal system can rupture the lysosomal vesicular membrane; however, it remains unclear whether lysosomal rupture leads to the transmission of \u03b1Syn aggregation. Here, we applied cell-based \u03b1Syn propagation models to show that ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy, i.e., selective autophagy of damaged lysosomes. \u03b1Syn aggregates accumulated predominantly in lysosomes, causing their rupture, and seeded the aggregation of endogenous \u03b1Syn, initially around damaged lysosomes. Exogenous \u03b1Syn aggregates induced the accumulation of LC3 on lysosomes. This LC3 accumulation was not observed in cells in which a key regulator of autophagy, RB1CC1/FIP200, was knocked out and was confirmed as lysophagy by transmission electron microscopy. Importantly, RB1CC1/FIP200-deficient cells treated with \u03b1Syn aggregates had increased numbers of ruptured lysosomes and enhanced propagation of \u03b1Syn aggregation. Furthermore, various types of lysosomal damage induced using lysosomotropic reagents, depletion of lysosomal enzymes, or more toxic species of \u03b1Syn fibrils also exacerbated the propagation of \u03b1Syn aggregation, and impaired lysophagy and lysosomal membrane damage synergistically enhanced propagation. These results indicate that lysophagy prevents exogenous \u03b1Syn aggregates from escaping the endosomal-lysosomal system and transmitting aggregation to endogenous cytosolic \u03b1Syn via ruptured lysosomal vesicles. Our findings suggest that the progression and severity of synucleinopathies are associated with damage to lysosomal membranes and impaired lysophagy."

Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons. We found that the initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44). Remarkably, we demonstrate that WDR44 knockdown markedly reduced de novo \u03b1-SYN aggregation in both neuronal cultures and in vivo, whereas WDR44 overexpression enhances \u03b1-SYN aggregation in PD patient-derived iPSC neurons. Consistent with its potential pathogenic involvement, WDR44 aberrantly accumulates in vivo and in the brains of PD patients, where it colocalizes with LB inclusions. Finally, we show that lysosome-associated \u03b1-SYN aggregates compromised lysosomal structure and function, leading to neuronal impairment, a phenotype worsened by WDR44 overexpression, linking early aggregation events to downstream toxicity. Together, these findings reveal the earliest dynamic stages of \u03b1-SYN oligomerization in living neurons and identify the WDR44-\u03b1-SYN interaction as a promising therapeutic target for reducing \u03b1-SYN pathology and enabling early intervention in PD."

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases."

A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs. Five polymer types-polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and nylon-66 (PA66)-were detected in the sample. The total MP burden was significantly greater in PD patients than in controls (21.36\u202f\u00b1\u202f8.42 vs. 13.56\u202f\u00b1\u202f5.92\u202f\u03bcg/g; p\u202f<\u202f0.01), with the greatest increases observed for PVC (1.49-fold), PP (2.74-fold) and PA66 (6.62-fold), whereas the PE and PS levels were not significantly different. LDIR and SEM analyses revealed diverse particle morphologies, with most polymers appearing as granular particles. In vitro assays further revealed that PVC and PP microplastics induced dopaminergic neuron apoptosis and increased the level of phosphorylated \u03b1-synuclein (p-\u03b1-syn), providing support for their potential neurotoxicity. Together, these findings indicate elevated blood MP levels in PD patients and offer preliminary evidence linking polymer exposure with PD-related neuronal vulnerability."

Hence, the present study was conducted to decipher the neurodegenerative potential of BPA in inducing Parkinson's disease like phenotypes in zebrafish. Zebrafish were subjected to chronic waterborne exposure to BPA for 56 days. Locomotor activities and neurobehavioral response were assessed by the NTDT (novel tank diving test), OFT (open field test), and LDPT (light-dark preference test). The oxidative stress markers and histopathological observation for pyknosis and chromatin condensation were carried out. Immunohistochemistry for activated caspase-3 and targeted proteins expression study was performed. The basic findings reveal that chronic BPA exposure significantly induces locomotor dysfunction through a significant decline in mean velocity and total distance traveled. As a measure of pyknosis and chromatin condensation, pyknotic and Hoechst positive neurons in telencephalon and diencephalon significantly increased by BPA exposure. A higher concentration of BPA adversely affects the neurobehavioral response, antioxidant status, and neuromorphology in zebrafish. Parkinson-relevant targeted protein expression viz. alpha-synuclein and LRRK2, were significantly upregulated, whereas tyrosine hydroxylase, NeuN, and Nurr1 were significantly downregulated in the zebrafish brain. As an indicator of cell death by apoptosis, the expression of activated caspase-3 was significantly increased in the BPA-exposed zebrafish brain. These basic results of the current study indicate that chronic waterborne exposure to BPA induces neuropathological manifestation leading to the development of motor dysfunction and Parkinsonism-like neurodegenerative phenotypes in zebrafish."

This pH homeostasis is a consequence of proton influx produced by a V-type H+-translocating ATPase (V-ATPase) and rapid proton efflux through an unidentified \"leak\" pathway. By performing a candidate expression screening, we discovered that the TMEM175 gene encodes a proton-activated, proton-selective channel (LyPAP) that is required for lysosomal H+ \"leak\" currents. The activity of LyPAP is most active when lysosomes are hyper-acidified, and cells lacking TMEM175 exhibit lysosomal hyper-acidification and impaired proteolytic degradation, both of which can be restored by optimizing lysosomal pH using pharmacological agents. Variants of TMEM175 that are associated with susceptibility to Parkinson disease (PD) cause a reduction in TMEM175-dependent LyPAP currents and lysosomal hyper-acidification. Hence, our studies not only reveal an essential H+-dissipating pathway in lysosomes, but also provide a molecular target to regulate pH-dependent lysosomal functions and associated pathologies."

The highly hydrophobic plastics enter living organisms through reversible interactions with biomolecules, forming biocoronas. Following recent reports on plastics breaching the blood-brain barrier, the binding behavior of human \u03b1-synuclein (h\u03b1Sn) with polyethylene-based (PE) plastics was evaluated by using molecular dynamics simulations and experimental methods. The results provided three important findings: (i) h\u03b1Sn transitions from an open helical to a compact conformation, enhancing intramolecular interactions, (ii) nonoxidized PE NPs (NPnonox) rapidly adsorb h\u03b1Sn, as supported by experimental data from dynamic light scattering and adsorption isotherms, altering its structure, and (iii) the oxidized NP (NPox) failed to capture h\u03b1Sn. These interactions were dominated by the N-terminal domain of h\u03b1Sn, with major contributions from hydrophobic amino acids. These findings raise concerns about the potential pharmacological effects of NP-protein interactions on human health."

We studied the effect of Bisphenol A (BPA) at concentrations of 0.5\u00a0mM and 1\u00a0mM, the concentration of 1\u00a0mM corresponding to Lowest Observed Adverse Effect Level (LOAEL) for humans in adult Drosophila melanogaster. The BPA induced oxidative stress was established by increased levels of malondialdehyde, reactive species, and decreased activity of the antioxidant enzymes superoxide dismutase and catalase, and detoxificant enzyme glutathione-S-transferase. Associated with oxidative stress, there was a reduction of acetylcholinesterase activity and a reduction of dopamine levels, which are related to the decreased locomotion activity as observed in negative geotaxis, open field and equilibrium behaviors in group exposed to 1\u00a0mM of BPA. Oxidative stress also impaired mitochondrial and cellular metabolic activity in the head causing an increase in the mortality of flies exposed to both BPA concentrations. Therefore, BPA induced Parkinsonian-like changes in flies and it is possible that the oxidative stress is closely related to this effect, providing new insights for future studies."

The maintenance of lysosomal homeostasis and lysosomal membrane integrity is facilitated by the AAA+ ATPase, VCP/p97 (VCP). However, the relationship between VCP and NLRP3 inflammasome activity remains unexplored. Here, we demonstrate that the VCP inhibitors, DBeQ and ML240 elicit the activation of NLRP3 inflammasome in bone marrow-derived macrophages (BMDMs) when used as activation stimuli. Moreover, genetic inhibition of VCP or VCP chemical inhibition enhances lysosomal membrane damage and augments LLoME-associated NLRP3 inflammasome activation in BMDMs. Similarly, VCP inactivation also augments NLRP3 inflammasome activation mediated by aggregated alpha-synuclein fibrils and lysosomal damage.

However, how lysosomes participate in the spreading of \u03b1-syn aggregates is unclear. Here, by using super-resolution (SR) and electron microscopy (EM), we find that \u03b1-syn fibrils affect the morphology of lysosomes and impair their function in neuronal cells. In addition, we demonstrate that \u03b1-syn fibrils induce peripheral redistribution of lysosomes, likely mediated by transcription factor EB (TFEB), increasing the efficiency of \u03b1-syn fibrils' transfer to neighboring cells. We also show that lysosomal membrane permeabilization (LMP) allows the seeding of soluble \u03b1-syn in cells that have taken up \u03b1-syn fibrils from the culture medium, and, more importantly, in healthy cells in coculture, following lysosome-mediated transfer of the fibrils. Moreover, we demonstrate that seeding occurs mainly at lysosomes in both donor and acceptor cells, after uptake of \u03b1-syn fibrils from the medium and following their transfer, respectively. Finally, by using a heterotypic coculture system, we determine the origin and nature of the lysosomes transferred between cells, and we show that donor cells bearing \u03b1-syn fibrils transfer damaged lysosomes to acceptor cells, while also receiving healthy lysosomes from them. These findings thus contribute to the elucidation of the mechanism by which \u03b1-syn fibrils spread through TNTs, while also revealing the crucial role of lysosomes, working as a Trojan horse for both seeding and propagation of disease pathology."

Here, we employed high-resolution untargeted lipidomics to map brain lipid perturbations in Drosophila melanogaster chronically exposed to polystyrene nanoplastics (PS- NPs). PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids, notably cardiolipins and phosphatidylethanolamines, accompanied by increased diacylglycerols/triacylglycerols and monounsaturated fatty acids and by lipid droplet expansion. Guided by these lipidomic signatures, targeted biochemical assays demonstrated depolarized mitochondrial membrane potential, elevated mitochondrial reactive-oxygen species, inhibition of respiratory-chain complexes I and IV, and a shift in NAD(H) and NADP(H) redox couples toward a reduced state and increasing lipid peroxidation. This redox imbalance was accompanied by decreased tyrosine-hydroxylase expression, dopamine depletion, and impaired locomotor behavior, hallmarks of Parkinson's disease (PD)-like neurodegeneration. Dopaminergic neurochemistry was impaired (tyrosine hydroxylase and dopamine decreased), with concomitant reduction of GABA, and locomotor and circadian deficits emerged. Remarkably, co-treatment with the antioxidant N-acetylcysteine (NAC) restored mitochondrial membrane potential, reduced mitochondrial ROS and lipid peroxidation, normalized neutral lipid and MUFA accumulation, and rescued neurotransmitter levels and behavior. Stable-isotope tracing confirmed disrupted TCA cycle flux after NPs exposure that was rescued by NAC. Collectively, these findings reveal lipidomic remodeling as a critical link between environmental NPs exposure and PD-like pathology, highlighting mitochondrial redox-lipid interactions as early determinants and support redox-directed interventions to mitigate risk."

However, the likelihood of developing PD with inherited LRRK2 pathogenic variants differs (a phenomenon known as \"reduced penetrance\"), with factors including age and geographic region, highlighting a potential role for lifestyle and environmental factors in disease onset. To investigate this, household dust samples from four different groups of individuals were analyzed using metabolomics/exposomics and metagenomics approaches: PD+/LRRK2+ (PD patients with pathogenic LRRK2 variants; n\u00a0=\u00a011), PD-/LRRK2+ (individuals with pathogenic LRRK2 variants but without PD diagnosis; n\u00a0=\u00a08), iPD (PD of unknown cause; n\u00a0=\u00a011), and a matched, healthy control group (n\u00a0=\u00a011). The dust was complemented with metabolomics and lipidomics of matched serum samples, where available. A total of 1,003 chemicals and 163 metagenomic operational taxonomic units (mOTUs) were identified in the dust samples, of which ninety chemicals and ten mOTUs were statistically significant (ANOVA p-value\u00a0<\u00a00.05). Reduced levels of 2-benzothiazolesulfonic acid (BThSO3) were found in the PD-/LRRK2+\u00a0group compared to the PD+/LRRK2+\u00a0. Among the significant chemicals tentatively identified in dust, two are hazardous chemical replacements: Bisphenol S (BPS), and perfluorobutane sulfonic acid (PFBuS). Furthermore, various lipids were found altered in serum including different lysophosphatidylethanolamines (LPEs), and lysophosphatidylcholines (LPCs), some with higher levels in the PD+/LRRK2+\u00a0group compared to the control group. A cellular study on isogenic neurons generated from a PD+/LRRK2+\u00a0patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis. This pilot study demonstrates how non-target metabolomics/exposomics analysis of indoor dust samples complemented with metagenomics can prioritize relevant chemicals that may be potential modifiers of LRRK2 penetrance."

Despite being widely used as a lysosomal marker, the physiological functions of the LAMP proteins have long been overlooked.

This LAMP inhibition mitigates the proton conduction of TMEM175 and facilitates lysosomal acidification to a lower pH environment crucial for optimal hydrolase activity.

This study examines the physiological and neurotoxic effects of these minuscule nanoplastic particles on the nematode Caenorhabditis elegans as well as on human cells. Here, we find that 25\u00a0nm polystyrene nanoplastic particles can inhibit animal growth and movement at very low concentrations, with varying effects on their surface groups. Furthermore, these nanoplastic particles not only accumulate in the digestive tract but also penetrate further into extraintestinal tissues. Such nanoplastics significantly compromise the integrity of the intestinal barrier, leading to \"leaky gut\" conditions and cause mitochondrial fragmentation in muscles, which possibly explains the observed movement impairments. A striking discovery was that these nanoplastics exacerbate symptoms similar to those of Parkinson's disease (PD), including dopaminergic neuronal degeneration, locomotor dysfunction, and accumulation of \u03b1-Synuclein aggregates. Importantly, our study demonstrates that the detrimental effects of nanoplastics on the aggregation of \u03b1-Synuclein extend to both C. elegans and human cell models of PD. In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems.

Importantly, in both C. elegans and human cell models of Parkinson's disease, such nanoplastics penetrate tissues or cells and increase \u03b1-Synuclein aggregates. This underscores the urgent need to understand the interactions of nanoplastics with biological systems and highlights potential environmental and health consequences."

Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions."

There is currently growing support for the hypothesis that genetic variants explain a significant fraction of the etiology of apparently sporadic parkinsonian disorders. Genetic risk factors can be stratified according to the metabolic or structural processes that can lead to cellular disturbance;\u00a0these processes involve protein aggregation, protein and membrane trafficking, stabilization of the neurite structure, prion-like transmission of pathological proteins, ubiquitin-proteasome system balance, mitophagy, lysosome autophagy, synaptic functions, and dopamine transmission. Regarding the environmental risk factors, there are several substances that have been supposed of being a risk for the development of neurodegenerative proteinopathy and Parkinsonism, mainly the agents used in agriculture and the textile industry. The most important and most frequently studied are pesticides and trichlorethylene. Beside the globally ubiquitous substances which are supposedly neurotoxic and exposure to which can cause manifestations of Parkinsonism, there are more geographically (regionally) specific substances, which cause (or quite recently caused) the manifestation of endemically present Parkinsonism.

We used LRRK2R1627P knock-in rats (human LRRK2-R1628P corresponds to rat LRRK2-R1627P) to investigate the R1627P mutation on function of dopaminergic neurons (DANs) and their susceptibility to the environmental toxin Lipopolysaccharide (LPS) during aging. LRRK2R1627P rats showed no significant loss of DANs, dopamine and its metabolites, or motor dysfunction; however, spontaneous exploration and olfactory discrimination reduced, and dendritic spines of DANs showed degeneration. We found decreased pThr73-Rab10 located on the trans-Golgi, disrupted Golgi structure and lipofuscin accumulation in aged LRRK2R1627P rat DANs, and the protein related to trans-Golgi complex and regulating lysosome function were significantly reduced. Although the neuroinflammation of brain was not obvious in the aging process, we confirmed a decrease in the ratio of CD4+/CD8+ and B cells, an increase in inflammatory factors (TLR4, NFKB, TNF-\u03b1) in the periphery. Furthermore, we demonstrated that the R1627P mutation caused the abnormal accumulation of \u03b1-Syn in the aged rat intestine. LPS exacerbated pathological \u03b1-Syn aggregation in the small intestine of LRRK2 transgenic rats and spread to the brain via the gut-brain axis. This led to microgliosis in the substantia nigra, creating a pro-inflammatory environment and inducing DANs degeneration. Gut-brain axis disruption may be a key determinant of progression to R1628P-PD in R1628P carriers.

This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

Recent studies have shown that extracellular \u03b1Syn aggregates taken up by the endosomal-lysosomal system can rupture the lysosomal vesicular membrane; however, it remains unclear whether lysosomal rupture leads to the transmission of \u03b1Syn aggregation. Here, we applied cell-based \u03b1Syn propagation models to show that ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy, i.e., selective autophagy of damaged lysosomes. \u03b1Syn aggregates accumulated predominantly in lysosomes, causing their rupture, and seeded the aggregation of endogenous \u03b1Syn, initially around damaged lysosomes. Exogenous \u03b1Syn aggregates induced the accumulation of LC3 on lysosomes. This LC3 accumulation was not observed in cells in which a key regulator of autophagy, RB1CC1/FIP200, was knocked out and was confirmed as lysophagy by transmission electron microscopy. Importantly, RB1CC1/FIP200-deficient cells treated with \u03b1Syn aggregates had increased numbers of ruptured lysosomes and enhanced propagation of \u03b1Syn aggregation. Furthermore, various types of lysosomal damage induced using lysosomotropic reagents, depletion of lysosomal enzymes, or more toxic species of \u03b1Syn fibrils also exacerbated the propagation of \u03b1Syn aggregation, and impaired lysophagy and lysosomal membrane damage synergistically enhanced propagation. These results indicate that lysophagy prevents exogenous \u03b1Syn aggregates from escaping the endosomal-lysosomal system and transmitting aggregation to endogenous cytosolic \u03b1Syn via ruptured lysosomal vesicles. Our findings suggest that the progression and severity of synucleinopathies are associated with damage to lysosomal membranes and impaired lysophagy."

Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons. We found that the initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44). Remarkably, we demonstrate that WDR44 knockdown markedly reduced de novo \u03b1-SYN aggregation in both neuronal cultures and in vivo, whereas WDR44 overexpression enhances \u03b1-SYN aggregation in PD patient-derived iPSC neurons. Consistent with its potential pathogenic involvement, WDR44 aberrantly accumulates in vivo and in the brains of PD patients, where it colocalizes with LB inclusions. Finally, we show that lysosome-associated \u03b1-SYN aggregates compromised lysosomal structure and function, leading to neuronal impairment, a phenotype worsened by WDR44 overexpression, linking early aggregation events to downstream toxicity. Together, these findings reveal the earliest dynamic stages of \u03b1-SYN oligomerization in living neurons and identify the WDR44-\u03b1-SYN interaction as a promising therapeutic target for reducing \u03b1-SYN pathology and enabling early intervention in PD."

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases."

In this study, we collected whole blood samples from 21 PD patients and 12 age- and sex-matched healthy controls under strict anticontamination protocols. A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs. Five polymer types-polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and nylon-66 (PA66)-were detected in the sample.

Hence, the present study was conducted to decipher the neurodegenerative potential of BPA in inducing Parkinson's disease like phenotypes in zebrafish. Zebrafish were subjected to chronic waterborne exposure to BPA for 56 days. Locomotor activities and neurobehavioral response were assessed by the NTDT (novel tank diving test), OFT (open field test), and LDPT (light-dark preference test). The oxidative stress markers and histopathological observation for pyknosis and chromatin condensation were carried out. Immunohistochemistry for activated caspase-3 and targeted proteins expression study was performed. The basic findings reveal that chronic BPA exposure significantly induces locomotor dysfunction through a significant decline in mean velocity and total distance traveled. As a measure of pyknosis and chromatin condensation, pyknotic and Hoechst positive neurons in telencephalon and diencephalon significantly increased by BPA exposure. A higher concentration of BPA adversely affects the neurobehavioral response, antioxidant status, and neuromorphology in zebrafish. Parkinson-relevant targeted protein expression viz. alpha-synuclein and LRRK2, were significantly upregulated, whereas tyrosine hydroxylase, NeuN, and Nurr1 were significantly downregulated in the zebrafish brain. As an indicator of cell death by apoptosis, the expression of activated caspase-3 was significantly increased in the BPA-exposed zebrafish brain. These basic results of the current study indicate that chronic waterborne exposure to BPA induces neuropathological manifestation leading to the development of motor dysfunction and Parkinsonism-like neurodegenerative phenotypes in zebrafish."

This pH homeostasis is a consequence of proton influx produced by a V-type H+-translocating ATPase (V-ATPase) and rapid proton efflux through an unidentified \"leak\" pathway. By performing a candidate expression screening, we discovered that the TMEM175 gene encodes a proton-activated, proton-selective channel (LyPAP) that is required for lysosomal H+ \"leak\" currents. The activity of LyPAP is most active when lysosomes are hyper-acidified, and cells lacking TMEM175 exhibit lysosomal hyper-acidification and impaired proteolytic degradation, both of which can be restored by optimizing lysosomal pH using pharmacological agents. Variants of TMEM175 that are associated with susceptibility to Parkinson disease (PD) cause a reduction in TMEM175-dependent LyPAP currents and lysosomal hyper-acidification. Hence, our studies not only reveal an essential H+-dissipating pathway in lysosomes, but also provide a molecular target to regulate pH-dependent lysosomal functions and associated pathologies."

The highly hydrophobic plastics enter living organisms through reversible interactions with biomolecules, forming biocoronas. Following recent reports on plastics breaching the blood-brain barrier, the binding behavior of human \u03b1-synuclein (h\u03b1Sn) with polyethylene-based (PE) plastics was evaluated by using molecular dynamics simulations and experimental methods. The results provided three important findings: (i) h\u03b1Sn transitions from an open helical to a compact conformation, enhancing intramolecular interactions, (ii) nonoxidized PE NPs (NPnonox) rapidly adsorb h\u03b1Sn, as supported by experimental data from dynamic light scattering and adsorption isotherms, altering its structure, and (iii) the oxidized NP (NPox) failed to capture h\u03b1Sn. These interactions were dominated by the N-terminal domain of h\u03b1Sn, with major contributions from hydrophobic amino acids. These findings raise concerns about the potential pharmacological effects of NP-protein interactions on human health."

One of these factors is oxidative stress induced by exposure to environmental toxifiers. We studied the effect of Bisphenol A (BPA) at concentrations of 0.5\u00a0mM and 1\u00a0mM, the concentration of 1\u00a0mM corresponding to Lowest Observed Adverse Effect Level (LOAEL) for humans in adult Drosophila melanogaster. The BPA induced oxidative stress was established by increased levels of malondialdehyde, reactive species, and decreased activity of the antioxidant enzymes superoxide dismutase and catalase, and detoxificant enzyme glutathione-S-transferase. Associated with oxidative stress, there was a reduction of acetylcholinesterase activity and a reduction of dopamine levels, which are related to the decreased locomotion activity as observed in negative geotaxis, open field and equilibrium behaviors in group exposed to 1\u00a0mM of BPA. Oxidative stress also impaired mitochondrial and cellular metabolic activity in the head causing an increase in the mortality of flies exposed to both BPA concentrations. Therefore, BPA induced Parkinsonian-like changes in flies and it is possible that the oxidative stress is closely related to this effect, providing new insights for future studies."

The maintenance of lysosomal homeostasis and lysosomal membrane integrity is facilitated by the AAA+ ATPase, VCP/p97 (VCP). However, the relationship between VCP and NLRP3 inflammasome activity remains unexplored. Here, we demonstrate that the VCP inhibitors, DBeQ and ML240 elicit the activation of NLRP3 inflammasome in bone marrow-derived macrophages (BMDMs) when used as activation stimuli. Moreover, genetic inhibition of VCP or VCP chemical inhibition enhances lysosomal membrane damage and augments LLoME-associated NLRP3 inflammasome activation in BMDMs. Similarly, VCP inactivation also augments NLRP3 inflammasome activation mediated by aggregated alpha-synuclein fibrils and lysosomal damage.

However, how lysosomes participate in the spreading of \u03b1-syn aggregates is unclear. Here, by using super-resolution (SR) and electron microscopy (EM), we find that \u03b1-syn fibrils affect the morphology of lysosomes and impair their function in neuronal cells. In addition, we demonstrate that \u03b1-syn fibrils induce peripheral redistribution of lysosomes, likely mediated by transcription factor EB (TFEB), increasing the efficiency of \u03b1-syn fibrils' transfer to neighboring cells. We also show that lysosomal membrane permeabilization (LMP) allows the seeding of soluble \u03b1-syn in cells that have taken up \u03b1-syn fibrils from the culture medium, and, more importantly, in healthy cells in coculture, following lysosome-mediated transfer of the fibrils. Moreover, we demonstrate that seeding occurs mainly at lysosomes in both donor and acceptor cells, after uptake of \u03b1-syn fibrils from the medium and following their transfer, respectively. Finally, by using a heterotypic coculture system, we determine the origin and nature of the lysosomes transferred between cells, and we show that donor cells bearing \u03b1-syn fibrils transfer damaged lysosomes to acceptor cells, while also receiving healthy lysosomes from them. These findings thus contribute to the elucidation of the mechanism by which \u03b1-syn fibrils spread through TNTs, while also revealing the crucial role of lysosomes, working as a Trojan horse for both seeding and propagation of disease pathology."

Here, we employed high-resolution untargeted lipidomics to map brain lipid perturbations in Drosophila melanogaster chronically exposed to polystyrene nanoplastics (PS- NPs). PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids, notably cardiolipins and phosphatidylethanolamines, accompanied by increased diacylglycerols/triacylglycerols and monounsaturated fatty acids and by lipid droplet expansion. Guided by these lipidomic signatures, targeted biochemical assays demonstrated depolarized mitochondrial membrane potential, elevated mitochondrial reactive-oxygen species, inhibition of respiratory-chain complexes I and IV, and a shift in NAD(H) and NADP(H) redox couples toward a reduced state and increasing lipid peroxidation. This redox imbalance was accompanied by decreased tyrosine-hydroxylase expression, dopamine depletion, and impaired locomotor behavior, hallmarks of Parkinson's disease (PD)-like neurodegeneration. Dopaminergic neurochemistry was impaired (tyrosine hydroxylase and dopamine decreased), with concomitant reduction of GABA, and locomotor and circadian deficits emerged. Remarkably, co-treatment with the antioxidant N-acetylcysteine (NAC) restored mitochondrial membrane potential, reduced mitochondrial ROS and lipid peroxidation, normalized neutral lipid and MUFA accumulation, and rescued neurotransmitter levels and behavior. Stable-isotope tracing confirmed disrupted TCA cycle flux after NPs exposure that was rescued by NAC. Collectively, these findings reveal lipidomic remodeling as a critical link between environmental NPs exposure and PD-like pathology, highlighting mitochondrial redox-lipid interactions as early determinants and support redox-directed interventions to mitigate risk."

However, the likelihood of developing PD with inherited LRRK2 pathogenic variants differs (a phenomenon known as \"reduced penetrance\"), with factors including age and geographic region, highlighting a potential role for lifestyle and environmental factors in disease onset. To investigate this, household dust samples from four different groups of individuals were analyzed using metabolomics/exposomics and metagenomics approaches: PD+/LRRK2+ (PD patients with pathogenic LRRK2 variants; n\u00a0=\u00a011), PD-/LRRK2+ (individuals with pathogenic LRRK2 variants but without PD diagnosis; n\u00a0=\u00a08), iPD (PD of unknown cause; n\u00a0=\u00a011), and a matched, healthy control group (n\u00a0=\u00a011). The dust was complemented with metabolomics and lipidomics of matched serum samples, where available. A total of 1,003 chemicals and 163 metagenomic operational taxonomic units (mOTUs) were identified in the dust samples, of which ninety chemicals and ten mOTUs were statistically significant (ANOVA p-value\u00a0<\u00a00.05).

A cellular study on isogenic neurons generated from a PD+/LRRK2+\u00a0patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis.

This LAMP inhibition mitigates the proton conduction of TMEM175 and facilitates lysosomal acidification to a lower pH environment crucial for optimal hydrolase activity.

This study examines the physiological and neurotoxic effects of these minuscule nanoplastic particles on the nematode Caenorhabditis elegans as well as on human cells. Here, we find that 25\u00a0nm polystyrene nanoplastic particles can inhibit animal growth and movement at very low concentrations, with varying effects on their surface groups. Furthermore, these nanoplastic particles not only accumulate in the digestive tract but also penetrate further into extraintestinal tissues. Such nanoplastics significantly compromise the integrity of the intestinal barrier, leading to \"leaky gut\" conditions and cause mitochondrial fragmentation in muscles, which possibly explains the observed movement impairments. A striking discovery was that these nanoplastics exacerbate symptoms similar to those of Parkinson's disease (PD), including dopaminergic neuronal degeneration, locomotor dysfunction, and accumulation of \u03b1-Synuclein aggregates. Importantly, our study demonstrates that the detrimental effects of nanoplastics on the aggregation of \u03b1-Synuclein extend to both C. elegans and human cell models of PD. In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems. ENVIRONMENTAL IMPLICATION: The escalating prevalence of nanoplastics in the environment due to widespread plastic usage raises potential health risks. Studies conducted on C. elegans indicate that even low concentrations of 25\u00a0nm polystyrene nanoplastics can impair growth and movement. These particles accumulate in the digestive system, compromising the intestinal barrier, causing \"leaky gut\", as well as inducing Parkinson's-like symptoms. Importantly, in both C. elegans and human cell models of Parkinson's disease, such nanoplastics penetrate tissues or cells and increase \u03b1-Synuclein aggregates. This underscores the urgent need to understand the interactions of nanoplastics with biological systems and highlights potential environmental and health consequences."

Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions."

These processes lead to the formation of pathological proteins, resulting in the brain diseases called synucleinopathies, tauopathies or TDP-43 proteinopathies. There is currently growing support for the hypothesis that genetic variants explain a significant fraction of the etiology of apparently sporadic parkinsonian disorders. Genetic risk factors can be stratified according to the metabolic or structural processes that can lead to cellular disturbance;\u00a0these processes involve protein aggregation, protein and membrane trafficking, stabilization of the neurite structure, prion-like transmission of pathological proteins, ubiquitin-proteasome system balance, mitophagy, lysosome autophagy, synaptic functions, and dopamine transmission. Regarding the environmental risk factors, there are several substances that have been supposed of being a risk for the development of neurodegenerative proteinopathy and Parkinsonism, mainly the agents used in agriculture and the textile industry. The most important and most frequently studied are pesticides and trichlorethylene. Beside the globally ubiquitous substances which are supposedly neurotoxic and exposure to which can cause manifestations of Parkinsonism, there are more geographically (regionally) specific substances, which cause (or quite recently caused) the manifestation of endemically present Parkinsonism. Among ten types of endemic Parkinsonism, three of them are thought to have an environmental cause: Western Pacific Parkinsonism, Caribbean Parkinsonism, and North France cluster of atypical Parkinsonism."

We used LRRK2R1627P knock-in rats (human LRRK2-R1628P corresponds to rat LRRK2-R1627P) to investigate the R1627P mutation on function of dopaminergic neurons (DANs) and their susceptibility to the environmental toxin Lipopolysaccharide (LPS) during aging. LRRK2R1627P rats showed no significant loss of DANs, dopamine and its metabolites, or motor dysfunction; however, spontaneous exploration and olfactory discrimination reduced, and dendritic spines of DANs showed degeneration. We found decreased pThr73-Rab10 located on the trans-Golgi, disrupted Golgi structure and lipofuscin accumulation in aged LRRK2R1627P rat DANs, and the protein related to trans-Golgi complex and regulating lysosome function were significantly reduced. Although the neuroinflammation of brain was not obvious in the aging process, we confirmed a decrease in the ratio of CD4+/CD8+ and B cells, an increase in inflammatory factors (TLR4, NFKB, TNF-\u03b1) in the periphery. Furthermore, we demonstrated that the R1627P mutation caused the abnormal accumulation of \u03b1-Syn in the aged rat intestine. LPS exacerbated pathological \u03b1-Syn aggregation in the small intestine of LRRK2 transgenic rats and spread to the brain via the gut-brain axis. This led to microgliosis in the substantia nigra, creating a pro-inflammatory environment and inducing DANs degeneration. Gut-brain axis disruption may be a key determinant of progression to R1628P-PD in R1628P carriers. This insight has important clinical implications and highlights the importance of monitoring and addressing gut-brain axis integrity in individuals with LRRK2 mutations."

However, the molecular mechanisms underlying PD-linked LMP and subsequent lysosomal defects remain virtually unknown, thereby precluding their potential therapeutic targeting. Here we show that the pro-apoptotic protein BAX (BCL2-associated X protein), which permeabilizes mitochondrial membranes in PD models and is activated in PD patients, translocates and internalizes into lysosomal membranes early following treatment with the parkinsonian neurotoxin MPTP, both in vitro and in vivo, within a time-frame correlating with LMP, lysosomal disruption, and autophagosome accumulation and preceding mitochondrial permeabilization and dopaminergic neurodegeneration. Supporting a direct permeabilizing effect of BAX on lysosomal membranes, recombinant BAX is able to induce LMP in purified mouse brain lysosomes and the latter can be prevented by pharmacological blockade of BAX channel activity. Furthermore, pharmacological BAX channel inhibition is able to prevent LMP, restore lysosomal levels, reverse AP accumulation, and attenuate mitochondrial permeabilization and overall nigrostriatal degeneration caused by MPTP, both in vitro and in vivo.

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

Here, we employed high-resolution untargeted lipidomics to map brain lipid perturbations in Drosophila melanogaster chronically exposed to polystyrene nanoplastics (PS- NPs). PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids, notably cardiolipins and phosphatidylethanolamines, accompanied by increased diacylglycerols/triacylglycerols and monounsaturated fatty acids and by lipid droplet expansion. Guided by these lipidomic signatures, targeted biochemical assays demonstrated depolarized mitochondrial membrane potential, elevated mitochondrial reactive-oxygen species, inhibition of respiratory-chain complexes I and IV, and a shift in NAD(H) and NADP(H) redox couples toward a reduced state and increasing lipid peroxidation. This redox imbalance was accompanied by decreased tyrosine-hydroxylase expression, dopamine depletion, and impaired locomotor behavior, hallmarks of Parkinson's disease (PD)-like neurodegeneration. Dopaminergic neurochemistry was impaired (tyrosine hydroxylase and dopamine decreased), with concomitant reduction of GABA, and locomotor and circadian deficits emerged. Remarkably, co-treatment with the antioxidant N-acetylcysteine (NAC) restored mitochondrial membrane potential, reduced mitochondrial ROS and lipid peroxidation, normalized neutral lipid and MUFA accumulation, and rescued neurotransmitter levels and behavior. Stable-isotope tracing confirmed disrupted TCA cycle flux after NPs exposure that was rescued by NAC. Collectively, these findings reveal lipidomic remodeling as a critical link between environmental NPs exposure and PD-like pathology, highlighting mitochondrial redox-lipid interactions as early determinants and support redox-directed interventions to mitigate risk."

Recent studies have shown that extracellular \u03b1Syn aggregates taken up by the endosomal-lysosomal system can rupture the lysosomal vesicular membrane; however, it remains unclear whether lysosomal rupture leads to the transmission of \u03b1Syn aggregation. Here, we applied cell-based \u03b1Syn propagation models to show that ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy, i.e., selective autophagy of damaged lysosomes. \u03b1Syn aggregates accumulated predominantly in lysosomes, causing their rupture, and seeded the aggregation of endogenous \u03b1Syn, initially around damaged lysosomes. Exogenous \u03b1Syn aggregates induced the accumulation of LC3 on lysosomes. This LC3 accumulation was not observed in cells in which a key regulator of autophagy, RB1CC1/FIP200, was knocked out and was confirmed as lysophagy by transmission electron microscopy. Importantly, RB1CC1/FIP200-deficient cells treated with \u03b1Syn aggregates had increased numbers of ruptured lysosomes and enhanced propagation of \u03b1Syn aggregation. Furthermore, various types of lysosomal damage induced using lysosomotropic reagents, depletion of lysosomal enzymes, or more toxic species of \u03b1Syn fibrils also exacerbated the propagation of \u03b1Syn aggregation, and impaired lysophagy and lysosomal membrane damage synergistically enhanced propagation. These results indicate that lysophagy prevents exogenous \u03b1Syn aggregates from escaping the endosomal-lysosomal system and transmitting aggregation to endogenous cytosolic \u03b1Syn via ruptured lysosomal vesicles. Our findings suggest that the progression and severity of synucleinopathies are associated with damage to lysosomal membranes and impaired lysophagy."

Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons. We found that the initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44).

Consistent with its potential pathogenic involvement, WDR44 aberrantly accumulates in vivo and in the brains of PD patients, where it colocalizes with LB inclusions. Finally, we show that lysosome-associated \u03b1-SYN aggregates compromised lysosomal structure and function, leading to neuronal impairment, a phenotype worsened by WDR44 overexpression, linking early aggregation events to downstream toxicity. Together, these findings reveal the earliest dynamic stages of \u03b1-SYN oligomerization in living neurons and identify the WDR44-\u03b1-SYN interaction as a promising therapeutic target for reducing \u03b1-SYN pathology and enabling early intervention in PD."

In this study, we collected whole blood samples from 21 PD patients and 12 age- and sex-matched healthy controls under strict anticontamination protocols. A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs. Five polymer types-polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and nylon-66 (PA66)-were detected in the sample. The total MP burden was significantly greater in PD patients than in controls (21.36\u202f\u00b1\u202f8.42 vs. 13.56\u202f\u00b1\u202f5.92\u202f\u03bcg/g; p\u202f<\u202f0.01), with the greatest increases observed for PVC (1.49-fold), PP (2.74-fold) and PA66 (6.62-fold), whereas the PE and PS levels were not significantly different. LDIR and SEM analyses revealed diverse particle morphologies, with most polymers appearing as granular particles. In vitro assays further revealed that PVC and PP microplastics induced dopaminergic neuron apoptosis and increased the level of phosphorylated \u03b1-synuclein (p-\u03b1-syn), providing support for their potential neurotoxicity. Together, these findings indicate elevated blood MP levels in PD patients and offer preliminary evidence linking polymer exposure with PD-related neuronal vulnerability."

Hence, the present study was conducted to decipher the neurodegenerative potential of BPA in inducing Parkinson's disease like phenotypes in zebrafish. Zebrafish were subjected to chronic waterborne exposure to BPA for 56 days. Locomotor activities and neurobehavioral response were assessed by the NTDT (novel tank diving test), OFT (open field test), and LDPT (light-dark preference test). The oxidative stress markers and histopathological observation for pyknosis and chromatin condensation were carried out. Immunohistochemistry for activated caspase-3 and targeted proteins expression study was performed. The basic findings reveal that chronic BPA exposure significantly induces locomotor dysfunction through a significant decline in mean velocity and total distance traveled. As a measure of pyknosis and chromatin condensation, pyknotic and Hoechst positive neurons in telencephalon and diencephalon significantly increased by BPA exposure. A higher concentration of BPA adversely affects the neurobehavioral response, antioxidant status, and neuromorphology in zebrafish. Parkinson-relevant targeted protein expression viz. alpha-synuclein and LRRK2, were significantly upregulated, whereas tyrosine hydroxylase, NeuN, and Nurr1 were significantly downregulated in the zebrafish brain. As an indicator of cell death by apoptosis, the expression of activated caspase-3 was significantly increased in the BPA-exposed zebrafish brain. These basic results of the current study indicate that chronic waterborne exposure to BPA induces neuropathological manifestation leading to the development of motor dysfunction and Parkinsonism-like neurodegenerative phenotypes in zebrafish."

This pH homeostasis is a consequence of proton influx produced by a V-type H+-translocating ATPase (V-ATPase) and rapid proton efflux through an unidentified \"leak\" pathway. By performing a candidate expression screening, we discovered that the TMEM175 gene encodes a proton-activated, proton-selective channel (LyPAP) that is required for lysosomal H+ \"leak\" currents. The activity of LyPAP is most active when lysosomes are hyper-acidified, and cells lacking TMEM175 exhibit lysosomal hyper-acidification and impaired proteolytic degradation, both of which can be restored by optimizing lysosomal pH using pharmacological agents. Variants of TMEM175 that are associated with susceptibility to Parkinson disease (PD) cause a reduction in TMEM175-dependent LyPAP currents and lysosomal hyper-acidification. Hence, our studies not only reveal an essential H+-dissipating pathway in lysosomes, but also provide a molecular target to regulate pH-dependent lysosomal functions and associated pathologies."

The highly hydrophobic plastics enter living organisms through reversible interactions with biomolecules, forming biocoronas. Following recent reports on plastics breaching the blood-brain barrier, the binding behavior of human \u03b1-synuclein (h\u03b1Sn) with polyethylene-based (PE) plastics was evaluated by using molecular dynamics simulations and experimental methods. The results provided three important findings: (i) h\u03b1Sn transitions from an open helical to a compact conformation, enhancing intramolecular interactions, (ii) nonoxidized PE NPs (NPnonox) rapidly adsorb h\u03b1Sn, as supported by experimental data from dynamic light scattering and adsorption isotherms, altering its structure, and (iii) the oxidized NP (NPox) failed to capture h\u03b1Sn. These interactions were dominated by the N-terminal domain of h\u03b1Sn, with major contributions from hydrophobic amino acids. These findings raise concerns about the potential pharmacological effects of NP-protein interactions on human health."

One of these factors is oxidative stress induced by exposure to environmental toxifiers. We studied the effect of Bisphenol A (BPA) at concentrations of 0.5\u00a0mM and 1\u00a0mM, the concentration of 1\u00a0mM corresponding to Lowest Observed Adverse Effect Level (LOAEL) for humans in adult Drosophila melanogaster. The BPA induced oxidative stress was established by increased levels of malondialdehyde, reactive species, and decreased activity of the antioxidant enzymes superoxide dismutase and catalase, and detoxificant enzyme glutathione-S-transferase. Associated with oxidative stress, there was a reduction of acetylcholinesterase activity and a reduction of dopamine levels, which are related to the decreased locomotion activity as observed in negative geotaxis, open field and equilibrium behaviors in group exposed to 1\u00a0mM of BPA. Oxidative stress also impaired mitochondrial and cellular metabolic activity in the head causing an increase in the mortality of flies exposed to both BPA concentrations. Therefore, BPA induced Parkinsonian-like changes in flies and it is possible that the oxidative stress is closely related to this effect, providing new insights for future studies."

The maintenance of lysosomal homeostasis and lysosomal membrane integrity is facilitated by the AAA+ ATPase, VCP/p97 (VCP). However, the relationship between VCP and NLRP3 inflammasome activity remains unexplored. Here, we demonstrate that the VCP inhibitors, DBeQ and ML240 elicit the activation of NLRP3 inflammasome in bone marrow-derived macrophages (BMDMs) when used as activation stimuli. Moreover, genetic inhibition of VCP or VCP chemical inhibition enhances lysosomal membrane damage and augments LLoME-associated NLRP3 inflammasome activation in BMDMs. Similarly, VCP inactivation also augments NLRP3 inflammasome activation mediated by aggregated alpha-synuclein fibrils and lysosomal damage.

However, how lysosomes participate in the spreading of \u03b1-syn aggregates is unclear. Here, by using super-resolution (SR) and electron microscopy (EM), we find that \u03b1-syn fibrils affect the morphology of lysosomes and impair their function in neuronal cells. In addition, we demonstrate that \u03b1-syn fibrils induce peripheral redistribution of lysosomes, likely mediated by transcription factor EB (TFEB), increasing the efficiency of \u03b1-syn fibrils' transfer to neighboring cells. We also show that lysosomal membrane permeabilization (LMP) allows the seeding of soluble \u03b1-syn in cells that have taken up \u03b1-syn fibrils from the culture medium, and, more importantly, in healthy cells in coculture, following lysosome-mediated transfer of the fibrils. Moreover, we demonstrate that seeding occurs mainly at lysosomes in both donor and acceptor cells, after uptake of \u03b1-syn fibrils from the medium and following their transfer, respectively. Finally, by using a heterotypic coculture system, we determine the origin and nature of the lysosomes transferred between cells, and we show that donor cells bearing \u03b1-syn fibrils transfer damaged lysosomes to acceptor cells, while also receiving healthy lysosomes from them. These findings thus contribute to the elucidation of the mechanism by which \u03b1-syn fibrils spread through TNTs, while also revealing the crucial role of lysosomes, working as a Trojan horse for both seeding and propagation of disease pathology."

However, the likelihood of developing PD with inherited LRRK2 pathogenic variants differs (a phenomenon known as \"reduced penetrance\"), with factors including age and geographic region, highlighting a potential role for lifestyle and environmental factors in disease onset. To investigate this, household dust samples from four different groups of individuals were analyzed using metabolomics/exposomics and metagenomics approaches: PD+/LRRK2+ (PD patients with pathogenic LRRK2 variants; n\u00a0=\u00a011), PD-/LRRK2+ (individuals with pathogenic LRRK2 variants but without PD diagnosis; n\u00a0=\u00a08), iPD (PD of unknown cause; n\u00a0=\u00a011), and a matched, healthy control group (n\u00a0=\u00a011). The dust was complemented with metabolomics and lipidomics of matched serum samples, where available. A total of 1,003 chemicals and 163 metagenomic operational taxonomic units (mOTUs) were identified in the dust samples, of which ninety chemicals and ten mOTUs were statistically significant (ANOVA p-value\u00a0<\u00a00.05). Reduced levels of 2-benzothiazolesulfonic acid (BThSO3) were found in the PD-/LRRK2+\u00a0group compared to the PD+/LRRK2+\u00a0. Among the significant chemicals tentatively identified in dust, two are hazardous chemical replacements: Bisphenol S (BPS), and perfluorobutane sulfonic acid (PFBuS). Furthermore, various lipids were found altered in serum including different lysophosphatidylethanolamines (LPEs), and lysophosphatidylcholines (LPCs), some with higher levels in the PD+/LRRK2+\u00a0group compared to the control group. A cellular study on isogenic neurons generated from a PD+/LRRK2+\u00a0patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis. This pilot study demonstrates how non-target metabolomics/exposomics analysis of indoor dust samples complemented with metagenomics can prioritize relevant chemicals that may be potential modifiers of LRRK2 penetrance."

This study examines the physiological and neurotoxic effects of these minuscule nanoplastic particles on the nematode Caenorhabditis elegans as well as on human cells. Here, we find that 25\u00a0nm polystyrene nanoplastic particles can inhibit animal growth and movement at very low concentrations, with varying effects on their surface groups. Furthermore, these nanoplastic particles not only accumulate in the digestive tract but also penetrate further into extraintestinal tissues. Such nanoplastics significantly compromise the integrity of the intestinal barrier, leading to \"leaky gut\" conditions and cause mitochondrial fragmentation in muscles, which possibly explains the observed movement impairments. A striking discovery was that these nanoplastics exacerbate symptoms similar to those of Parkinson's disease (PD), including dopaminergic neuronal degeneration, locomotor dysfunction, and accumulation of \u03b1-Synuclein aggregates. Importantly, our study demonstrates that the detrimental effects of nanoplastics on the aggregation of \u03b1-Synuclein extend to both C. elegans and human cell models of PD. In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems.

Importantly, in both C. elegans and human cell models of Parkinson's disease, such nanoplastics penetrate tissues or cells and increase \u03b1-Synuclein aggregates.

Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions."

These processes lead to the formation of pathological proteins, resulting in the brain diseases called synucleinopathies, tauopathies or TDP-43 proteinopathies. There is currently growing support for the hypothesis that genetic variants explain a significant fraction of the etiology of apparently sporadic parkinsonian disorders. Genetic risk factors can be stratified according to the metabolic or structural processes that can lead to cellular disturbance;\u00a0these processes involve protein aggregation, protein and membrane trafficking, stabilization of the neurite structure, prion-like transmission of pathological proteins, ubiquitin-proteasome system balance, mitophagy, lysosome autophagy, synaptic functions, and dopamine transmission. Regarding the environmental risk factors, there are several substances that have been supposed of being a risk for the development of neurodegenerative proteinopathy and Parkinsonism, mainly the agents used in agriculture and the textile industry. The most important and most frequently studied are pesticides and trichlorethylene. Beside the globally ubiquitous substances which are supposedly neurotoxic and exposure to which can cause manifestations of Parkinsonism, there are more geographically (regionally) specific substances, which cause (or quite recently caused) the manifestation of endemically present Parkinsonism. Among ten types of endemic Parkinsonism, three of them are thought to have an environmental cause: Western Pacific Parkinsonism, Caribbean Parkinsonism, and North France cluster of atypical Parkinsonism."

We used LRRK2R1627P knock-in rats (human LRRK2-R1628P corresponds to rat LRRK2-R1627P) to investigate the R1627P mutation on function of dopaminergic neurons (DANs) and their susceptibility to the environmental toxin Lipopolysaccharide (LPS) during aging. LRRK2R1627P rats showed no significant loss of DANs, dopamine and its metabolites, or motor dysfunction; however, spontaneous exploration and olfactory discrimination reduced, and dendritic spines of DANs showed degeneration. We found decreased pThr73-Rab10 located on the trans-Golgi, disrupted Golgi structure and lipofuscin accumulation in aged LRRK2R1627P rat DANs, and the protein related to trans-Golgi complex and regulating lysosome function were significantly reduced. Although the neuroinflammation of brain was not obvious in the aging process, we confirmed a decrease in the ratio of CD4+/CD8+ and B cells, an increase in inflammatory factors (TLR4, NFKB, TNF-\u03b1) in the periphery. Furthermore, we demonstrated that the R1627P mutation caused the abnormal accumulation of \u03b1-Syn in the aged rat intestine. LPS exacerbated pathological \u03b1-Syn aggregation in the small intestine of LRRK2 transgenic rats and spread to the brain via the gut-brain axis. This led to microgliosis in the substantia nigra, creating a pro-inflammatory environment and inducing DANs degeneration. Gut-brain axis disruption may be a key determinant of progression to R1628P-PD in R1628P carriers. This insight has important clinical implications and highlights the importance of monitoring and addressing gut-brain axis integrity in individuals with LRRK2 mutations."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

The literature also notes mitochondrial dysfunction and oxidative stress as parallel or upstream drivers [ID: 41980172, 41904737]. The synthesis appropriately lists these as contributors rather than replacing them, maintaining overall fidelity to the source data.\n    *   **Quote Attribution:** The synthesis correctly references the role of WDR44 in $\\alpha$-synuclein aggregation at the lysosomal membrane [ID: 41993512] and the role of lysophagy as a defensive mechanism [ID: 38147546], both of which are present in the provided source materials.\n\n### Conclusion\nThe synthesis is **substantially veridical** and demonstrates a high degree of fidelity to the provided literature. It avoids \"hallucinations\" by grounding its assertions in specific, cited mechanisms. The phrasing used\u2014that these agents \"act as a catalyst\"\u2014is supported by the cited experimental evidence showing that pollutant-induced lysosomal damage correlates with or causes increased aggregation rates [ID: 41580402, 39883073].

Chronic exposure to these contaminants triggers oxidative stress and mitochondrial dysfunction, forming a feed-forward mechanism that sustains neuroinflammation and neurodegeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe convergence of environmental MNP and BPA exposure on the lysosomal-autophagy pathway represents a critical mechanism of neurotoxic damage. Evidence demonstrates that $\\alpha$-synuclein, the protein central to PD, misfolds upon binding to MNP surfaces, transitioning from an open helical conformation to an aggregated state. The internalization of these plastic particles triggers significant lysosomal dysfunction. Specifically, internalized NPs accumulate in endolysosomal systems, inducing lysosomal membrane permeabilization (LMP) and releasing lysosomal enzymes into the cytosol, which precipitates cellular death pathways and worsens $\\alpha$-synuclein pathology. Similarly, BPA and its derivatives exacerbate these pathways by promoting oxidative stress and inducing mitochondrial dysfunction. The interaction between these contaminants and key cellular organelles like the mitochondria and lysosomes leads to a collapse in autophagic flux, preventing the clearance of misfolded proteins and thereby accelerating the progression of Parkinsonian-like neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics form disease-specific protein coronas, such as lysozyme-enriched coronas, which modulate immune signaling and contribute to systemic pathology.\n*   Alpha-synuclein structural folding is polymer-specific; polystyrene nanoplastics induce partial aggregation, while other plastic types may show different protein-binding affinities.\n*   The gut-brain axis is a primary site of initial MNP-induced pathology, where microbial dysbiosis acts as a precursor to systemic neuroinflammation.\n*   GSDMD-N, typically associated with pyroptosis, can translocate to mitochondrial membranes to amplify reactive oxygen species and facilitate lysosomal rupture.\n*   Small-molecule chaperones, such as ginsenoside Rg1 or specific natural extracts, have shown potential in restoring lysosomal acidification and clearing alpha-synuclein.\n*   The physical field disturbance coupled with advanced oxidation processes offers a mechanism-based strategy for cleaning BPA/NP-polluted water sources.\n*   Ferritinophagy, driven by lysosomal membrane disruption, results in iron accumulation, which further catalyzes oxidative injury and ferroptosis in dopaminergic systems.\n*   Lysosomal membrane stability serves as a conserved biomarker for microplastic-induced stress across diverse phylogenetic lineages, from marine invertebrates to mammalian tissues.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Evidence indicates that these pollutants disrupt the autophagy-lysosome pathway, induce lysosomal membrane permeabilization (LMP), and trigger oxidative stress, which collectively converge on the pathological accumulation of alpha-synuclein.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nEnvironmental pollutants, specifically micro/nanoplastics and bisphenols, modulate the pathogenesis of Parkinson's Disease. Through the disruption of lysosomal acidification and the subsequent induction of lysosomal membrane permeabilization (LMP), these agents impair the autophagic-lysosomal pathway's ability to clear alpha-synuclein, thereby accelerating disease-associated neurodegeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe neurodegenerative trajectory of Parkinson's Disease is increasingly understood as a convergence of genetic vulnerability and environmental insult. The provided literature delineates a clear mechanistic bridge between environmental plastic/phenolic pollutants and PD pathology. Microplastics and nanoplastics penetrate the central nervous system, where they actively interfere with the lysosome's structural and functional capacity. Lysosomal membrane permeabilization, often triggered by zinc-mediated stress or direct surface binding, prevents the orderly degradation of alpha-synuclein, the hallmark protein of Lewy bodies. Similarly, bisphenol compounds initiate oxidative and endoplasmic reticulum stress, which suppresses lysosomal autophagy and exacerbates the aggregation of misfolded proteins.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics can cross the blood-brain barrier via multiple routes, including olfactory and circumventricular pathways, particularly when barrier integrity is compromised.\n*   The initiation of alpha-synuclein aggregation predominantly occurs at the lysosomal membrane surface.\n*   Zinc homeostasis serves as a vital regulatory nexus where mitochondrial dysfunction links to lysosomal failure via intracellular zinc accumulation.\n*   Polystyrene nanoplastics have been observed to trigger microglial M1 activation, which propagates neuroinflammation through a feedforward loop.\n*   There exists a \"charge-specific injury\" paradigm where surface properties of nanoplastics determine whether they trigger hepatocyte ferroptosis or endothelial senescence.\n*   Taurine depletion is a predictive biomarker for microplastic-induced cognitive decline and synaptic loss.\n*   GCase enzyme activity is a genetic convergence point for lysosomal degradation failure in both GBA1-mutant and environmentally stressed PD models.\n*   A \"kidney-brain axis\" in PD pathogenesis suggests that peripheral alpha-synuclein aggregates in renal tissues may precede systemic spread to the central nervous system.\n*   Small EPs or \"SECmeres\" (sub-50nm particles) in blood are emerging as potentially superior biomarkers compared to classical extracellular vesicles for brain-specific signatures.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Evidence demonstrates that these exogenous agents can induce lysosomal membrane permeabilization (LMP), which directly facilitates the transmission of \u03b1-synuclein aggregates.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific research confirms that environmental pollutants, including nanoplastics and endocrine-disrupting chemicals like bisphenol, disrupt cellular proteostasis. These substances promote alpha-synuclein misfolding and aggregation, partially through the impairment of lysosomal-autophagy pathways (ALP) and the induction of lysosomal membrane damage. This disruption creates a feed-forward cycle where impaired degradation increases protein toxicity and further exacerbates lysosomal fragility.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic aggregation of \u03b1-synuclein is a central feature of Parkinson's disease (PD). The recent literature establishes that exogenous environmental triggers, such as PS-NPs and BPA, initiate or amplify this pathology by compromising the integrity of the endolysosomal system. Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain. Once these particles reach the brain, they exert deleterious effects on cellular homeostasis. \n\nThe mechanism involves complex organellar stress. PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids. This mitochondrial dysfunction is intimately linked to lysosomal status. Disrupting the LAMP-TMEM175 interaction alkalinizes the lysosomal pH and compromises the lysosomal hydrolytic function. Furthermore, pharmacological BAX channel inhibition is able to prevent LMP, restore lysosomal levels, reverse AP accumulation, and attenuate mitochondrial permeabilization and overall nigrostriatal degeneration caused by MPTP. \n\nThe direct link between membrane damage and aggregation is substantiated: ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy. Thus, pollutants that provoke LMP or inhibit lysophagy serve as fundamental drivers of disease progression.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics can cross the blood-brain barrier (BBB) within 1.5 hours and induce cell-specific inflammatory responses in astrocytes and microglia.\n*   WDR44 is a newly identified adaptor protein that facilitates \u03b1-synuclein aggregation specifically at the lysosomal membrane.\n*   Anionic nanoplastics specifically interact with the non-amyloid component (NAC) domain of \u03b1-synuclein to induce fibril formation.\n*   The initiation of \u03b1-synuclein aggregation is now visualized as a dynamic, membrane-associated event rather than a purely cytosolic one.\n*   Lysophagy, the selective autophagy of ruptured lysosomes, acts as a primary cellular defense mechanism to stop the \"seeding\" of \u03b1-synuclein aggregation in the cytosol.\n*   The interaction between PS-NPs and \u03b1-synuclein changes the protein structure from an open helical state to a compact, aggregation-prone conformation.\n*   Even low-dose, long-term exposure to nanoplastics (0.1 \u03bcg/L) is sufficient to induce measurable Parkinsonian-like behaviors in experimental models.\n*   BPA and its derivatives induce neurotoxicity via multiple channels, including oxidative stress and the downregulation of tyrosine hydroxylase.\n*   The gut-brain axis is a confirmed route for the propagation of pollutant-induced proteinopathies.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases."

This review synthesizes recent research findings to provide a comprehensive overview of the effects of MPs/NPs on the brain. Evidence demonstrates that MPs/NPs can cross critical biological barriers, including the blood-brain barrier and the placenta, gaining access to the central nervous system (CNS) and the developing fetal brain, influenced by particle size, charge, and the biomolecular corona. Once present, MPs/NPs trigger multiple detrimental pathways, including oxidative stress, persistent neuroinflammation involving microglia and astrocytes, mitochondrial dysfunction leading to energy deficits, disruption of crucial neurotransmitter systems, and direct neuronal damage. Critically, NPs have been shown to promote the aggregation of proteins implicated in neurodegeneration, such as alpha-synuclein. These mechanistic disturbances translate into observable adverse outcomes in experimental models, ranging from cognitive impairments in learning and memory to behavioral abnormalities and pathologies resembling human neurodegenerative and neurodevelopmental disorders. Toxicity is modulated by particle characteristics, co-exposures, and host factors like age and sex, with indirect effects via the gut-brain axis also playing a significant role. While current evidence, primarily from animal models often using high doses, strongly indicates a neurotoxic potential, significant research gaps remain concerning human risk assessment under chronic, low-level environmental exposure conditions and the effects of environmentally aged, mixed-plastic particles. Future research should prioritize human studies, environmentally realistic exposure scenarios, and differentiating direct versus indirect neurotoxic mechanisms to accurately evaluate the threat MPs/NPs pose to human brain health."

However, the precise toxicological mechanisms remain elusive. Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes. This study provided novel mechanistic insights into MPs-induced hepatotoxicity, identifying GSDMD-N as a potential central hub coordinating multiple cell death modalities."

However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution."

This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA."

Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions."

A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs.

Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of \u03b1 synuclein (\u03b1S) via the enteric nervous system, or the so-called gut-brain axis. Here we first examined the effect of enteric exposure to polystyrene nanoplastics on the peripheral and central pathogenesis of A53T, a representative \u03b1S mutant. Specifically, the polystyrene nanoplastics accelerated the amyloid aggregation of A53T \u03b1S, which subsequently elevated the in vitro production of glial activation biomarkers, cytokines, and reactive oxygen species and compromised mitochondrial and lysosomal membrane integrity, further shifting cellular metabolite profiles in association with PD pathophysiology. In vivo, coadministration of the polystyrene nanoplastics and A53T \u03b1S facilitated their synergistic gut-to-brain transmission in mice, leading to progressive impairment of physical and motor skills in resemblance to characteristic PD symptoms.

The benthic polychaete Hediste diversicolor was exposed to these treatments for 7 days through spiked sediments, simulating realistic environmental conditions. The MPs used were particles smaller than 30\u202f\u00b5m, composed of a mixture of polymers, including PE, PET, PP, LDPE, HDPE, and PEVA, with varied morphologies such as fragments, fibers, and films. Analyses revealed that both MPs and B[a]P were internalized by coelomocytes, with MPs enhancing B[a]P bioaccumulation. Combined exposures led to marked cytotoxic and genotoxic effects, evidenced by decreased lysosomal membrane stability (LMS), elevated micronuclei frequency (FMN), and increased DNA fragmentation, as assessed by terminal dUTP nick-end labeling (TUNEL) assay. Co-exposure also altered apoptotic and DNA repair pathways, as demonstrated by upregulation of P53, Bax, and Casp-3, alongside downregulation of the anti-apoptotic marker Bcl-2. These findings suggest that co-exposure intensifies cellular damage and apoptotic signaling. Overall, this study underscores the risks of MPs in marine ecosystems, particularly their role in accumulating and transferring harmful substances affecting biota health."

Cathepsin D (CTSD), a lysosomal hydrolase essential for \u03b1-syn clearance, becomes functionally impaired when its maturation is disrupted, exacerbating proteostatic stress. This study investigated whether ginsenoside Rg1(Rg1) restores CTSD maturation and lysosomal function to mitigate PD pathology. MPTP-induced zebrafish and mouse PD models, as well as MPP+-treated SH-SY5Y cells, animals and cells were treated with Rg1 at different concentrations. Motor behavior, dopaminergic neuron survival, \u03b1-syn clearance, CTSD maturation, lysosomal activity, endoplasmic reticulum (ER) stress, oxidative stress, autophagic flux, and apoptosis were systematically evaluated. Rg1 improved locomotor performance and preserved dopaminergic neurons, promoted \u03b1-syn clearance, and enhanced CTSD maturation in lysosomes. These effects coincided with reduced ER and oxidative stress, normalized autophagic flux, and decreased apoptosis. Rg1 functions as a natural lysosomal enhancer, restoring lysosome-ER homeostasis and counteracting multiple pathogenic pathways in PD. The findings reveal a CTSD-dependent regulatory axis in \u03b1-syn homeostasis and highlight Rg1 as a promising multi-target therapeutic candidate for PD."

Recent evidence suggests that microplastic exposure may trigger such ferroptosis-related pathologies. However, the mechanism and impact of ferroptosis-induced cerebral cortex damage in waterfowl due to microplastic exposure remain unclear. In this study, Muscovy ducks were divided into three groups receiving: pure water, 1\u202fmg\u00b7L\u207b\u00b9\u202fpolyvinyl chloride microplastics (PVC-MPs), or 10\u202fmg\u00b7L\u207b\u00b9\u202fPVC-MPs for two months. This study suggests that PVC-MPs may accumulate in the duck cerebral cortical tissue, where they disrupt blood-brain barrier (BBB) integrity as manifested by ultrastructural damage and significant downregulation of tight junction protein levels (ZO-1, Occludin, and Claudin-5). Moreover, PVC-MPs exposure induced histopathological and nuclear ultrastructural damage, along with oxidative stress and excessive iron accumulation, both hallmarks of ferroptosis. Specifically, PVC-MPs triggered mitochondrial cristae fragmentation and shrinkage, as well as lipid peroxidation accumulation, evidenced by elevated MDA levels. Western blot analysis confirmed ferroptosis through significant downregulation of SLC7A11, GPX4, and FTH1, and upregulation of COX2. In conclusion, this study suggests that PVC-MPs may accumulate in the duck cerebral cortex, where they disrupt BBB integrity and induce histopathological damage, as well as disturb redox homeostasis and trigger ferroptosis, ultimately leading to neuronal injury."

We applied an integrative approach combining network toxicology, Mendelian randomization, molecular docking, and single-cell transcriptomics to identify BPA-responsive targets relevant to ischemic stroke. CX3CL1 was prioritized based on network centrality, genetic association with stroke risk, and endothelial enrichment in post-ischemic brain tissue. Functional validation was performed in bEnd.3 brain endothelial cells and an endothelial-astrocyte Transwell blood-brain barrier (BBB) co-culture model subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Under normoxic conditions, BPA (50 and 100\u202f\u03bcM) did not markedly reduce cell viability; however, it significantly aggravated OGD/R-induced injury. BPA increased endothelial apoptosis (10.1% and 21.2% vs. 4.6% under OGD/R alone), elevated CX3CL1 protein expression (1.71- and 2.28-fold vs. control), increased BAX, and reduced Bcl-2 levels. Tight junction proteins were substantially decreased (claudin-5: 0.49 and 0.24; ZO-1: 0.46 and 0.23 relative to control), accompanied by reduced transendothelial electrical resistance and increased FITC-dextran permeability.

After release into aquatic systems, photo-oxidation, mechanical abrasion, fragmentation, and biofilm-associated aging modify their surface chemistry, morphology, polarity, and reactivity. Simultaneously, natural organic matter, humic substances, extracellular polymeric substances, proteins, lipids, and microbial products adsorb onto plastic surfaces, forming eco-coronas that regulate aggregation, colloidal stability, contaminant partitioning, and desorption behavior. A central unresolved question is how eco-corona-coated particles are remodeled after organismal entry, how environmental coronas are exchanged into bio-coronas within mucus, gut, gill, and tissue microenvironments, and how these dynamic interfaces control the toxicokinetics of coexisting pollutants. This review synthesizes current evidence to define when weathered microplastics and nanoplastics act as vectors, sinks, amplifiers, or neutral carriers of co-pollutants. We emphasize internal exposure, bioaccessibility, residence time, and tissue distribution rather than nominal water concentrations or adsorption capacity alone. Classical modeling indicates that, for many hydrophobic organic contaminants, chemical flux from natural prey, sediments, and organic matter may exceed that from ingested plastics under typical environmental conditions, requiring scenario-specific interpretation. However, this logic should not be generalized to antibiotics, pharmaceuticals, metals, and per- and polyfluoroalkyl substances, whose interactions may depend on electrostatics, ionization, hydrogen bonding, cation bridging, corona chemistry, and gut-phase desorption. We propose a predictive framework linking plastic aging, eco-corona formation, bio-corona remodeling, partitioning/desorption kinetics, uptake, retention, translocation, and organism-level outcomes. Finally, within an explicitly aquatic scope, we outline minimum reporting requirements to improve comparability, mechanistic interpretation, and risk relevance in microplastic-mixture toxicology, including clearer reporting of particle-size class, size distribution, hydrodynamic diameter after corona formation, and size-dependent uptake or translocation outcomes."

Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration."

Their capacity to adsorb, transport, and release contaminants has raised growing concern over mixture toxicity under realistic exposure scenarios. This review systematically examines the mechanistic basis of MNPs-mediated combined toxicity and evaluates the emerging role of network toxicology as a systems-based tool for hazard assessment. MNPs alter the bioavailability, environmental fate, tissue distribution, and intracellular delivery of associated pollutants through hydrophobic, electrostatic, and other intermolecular interactions. Carrier-mediated uptake, particularly the \"Trojan horse\"\u00a0effect, appears to be a major driver of non-additive toxicity in co-exposure systems. We then outline the core workflow of network toxicology, encompassing target identification, network construction, pathway enrichment, and experimental validation, and discuss its application in decoding mixture toxicity. Oxidative stress, inflammatory signaling, metabolic disturbance, barrier dysfunction, and programmed cell death emerge as conserved and interconnected pathways underlying synergistic multi-organ injury. These findings indicate that toxicity in complex exposure systems is governed not only by the intrinsic properties of particles or chemicals, but also by their dynamic physicochemical and biological interactions. We further assess current advances and limitations in network toxicology and propose a next-generation risk assessment (NGRA)-oriented framework to support mechanism-based risk assessment and regulatory decision-making. Although current evidence is dominated by binary, high-dose laboratory studies, network toxicology offers strong potential as a new approach methodology (NAM) for predictive evaluation of environmentally relevant mixtures.

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L.

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function.

Chronic exposure to these contaminants triggers oxidative stress and mitochondrial dysfunction, forming a feed-forward mechanism that sustains neuroinflammation and neurodegeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe convergence of environmental MNP and BPA exposure on the lysosomal-autophagy pathway represents a critical mechanism of neurotoxic damage. Evidence demonstrates that $\\alpha$-synuclein, the protein central to PD, misfolds upon binding to MNP surfaces, transitioning from an open helical conformation to an aggregated state. The internalization of these plastic particles triggers significant lysosomal dysfunction. Specifically, internalized NPs accumulate in endolysosomal systems, inducing lysosomal membrane permeabilization (LMP) and releasing lysosomal enzymes into the cytosol, which precipitates cellular death pathways and worsens $\\alpha$-synuclein pathology. Similarly, BPA and its derivatives exacerbate these pathways by promoting oxidative stress and inducing mitochondrial dysfunction. The interaction between these contaminants and key cellular organelles like the mitochondria and lysosomes leads to a collapse in autophagic flux, preventing the clearance of misfolded proteins and thereby accelerating the progression of Parkinsonian-like neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics form disease-specific protein coronas, such as lysozyme-enriched coronas, which modulate immune signaling and contribute to systemic pathology.\n*   Alpha-synuclein structural folding is polymer-specific; polystyrene nanoplastics induce partial aggregation, while other plastic types may show different protein-binding affinities.\n*   The gut-brain axis is a primary site of initial MNP-induced pathology, where microbial dysbiosis acts as a precursor to systemic neuroinflammation.\n*   GSDMD-N, typically associated with pyroptosis, can translocate to mitochondrial membranes to amplify reactive oxygen species and facilitate lysosomal rupture.\n*   Small-molecule chaperones, such as ginsenoside Rg1 or specific natural extracts, have shown potential in restoring lysosomal acidification and clearing alpha-synuclein.\n*   The physical field disturbance coupled with advanced oxidation processes offers a mechanism-based strategy for cleaning BPA/NP-polluted water sources.\n*   Ferritinophagy, driven by lysosomal membrane disruption, results in iron accumulation, which further catalyzes oxidative injury and ferroptosis in dopaminergic systems.\n*   Lysosomal membrane stability serves as a conserved biomarker for microplastic-induced stress across diverse phylogenetic lineages, from marine invertebrates to mammalian tissues.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This study evaluated the isolated and interactive toxicity of alone linear low-density polyethylene (LLDPE) (0, 5, 50, 500\u202fmg\u202fL-1) and BaP (0, 3, 12, 21, 30\u202f\u03bcg\u202fL-1) in the mangrove oyster Crassostrea gasar, a key filter-feeding species highly vulnerable to particulate and hydrophobic contaminants. The concentrations of 5\u202fmg/L MPs and all BaP concentrations tested are environmentally relevant. Adult oysters were exposed for 7 days in a full factorial design, and biomarkers (Glutathione S-transferase, Glutathione Peroxidase, Reduced Glutathione, Lipid Peroxidation, DNA damage, Neutral Red Retention Time) were assessed in gills and hemolymph. Alone MPs alone induced oxidative and cytogenotoxic effects, confirming that even uncontaminated plastic particles can disrupt cellular homeostasis. Significant interactive effects between MPs and BaP were observed, particularly influencing oxidative stress and DNA integrity. GPx, GST, and GSH responses were associated with DNA damage at higher exposure levels. BaP increased lipid peroxidation, reducing lysosomal membrane stability, and this impairment was exacerbated under combined exposure. The integrated biomarker response index identified the combination of 30\u202f\u03bcg\u202fL-1 BaP and 500\u202fmg\u202fL-1 MP as the most hazardous scenario. The environmentally relevant MP concentration (5\u202fmg\u202fL-1) also produced significant effects when combined with BaP. These findings demonstrate that MPs modulate BaP toxicity and highlight the importance of assessing co-contaminant interactions in filter-feeding organisms. Although the highest concentration tested (500\u202fmg\u202fL-1) exceeds environmental levels, effects were also observed at environmentally relevant concentrations. The inclusion of elevated concentrations was intended to identify effect thresholds and underlying mechanisms, providing robust data for environmental risk assessment.\n\nID: 42213153\nTitle: Biomarker Responses in the Marine Mussel Mytilus Edulis Indicate Significant Toxicological Effects of Polyethylene Microplastics.\nAbstract: This study investigated the short\u2011term effects of polyethylene microplastics (PE\u2011MPs) on the marine mussel Mytilus edulis using a suite of cellular and subcellular biomarkers. A total of 225 mussels were collected from Umluj, Saudi Arabia, a relatively unimpacted coastal area of the Red Sea, and experimentally exposed for 72\u00a0h to spherical PE\u2011MPs (50\u00a0\u03bcm diameter) at nominal concentrations of 5, 10, 20, and 60 particles L-1. Genotoxicity, oxidative status, and cellular integrity were assessed by comet assay, thiobarbituric acid\u2011reactive substances (TBARS), superoxide dismutase (SOD) activity, and lysosomal membrane stability (LMS). At 60 particles L-1, DNA strand breakage increased markedly in hemocytes (13.09%) and gill cells (12.21%) relative to controls (2.14%; p\u2009<\u20090.01). Lipid peroxidation was 1.28 nmol TBARS mg protein-1, and activity of gill SOD was decreased by 16.13% of control. LMS was significantly reduced from 134.4\u00a0min in controls to 53.2\u00a0min in the highest exposure (p\u2009<\u20090.01), suggesting impaired cellular homeostasis. Given the short exposure duration, these results are preliminary. They indicate that acute PE-MP exposure at the tested concentrations is associated with measurable genotoxicity, oxidative stress, and reduced lysosomal stability. Longer-term ecological implications remain to be investigated.\n\nID: 42009103\nTitle: Nanoplastics exposure accelerates the progression of osteoarthritis via lysosomal destabilization-mediated pyroptosis.\nAbstract: Nanoplastics (NPs), as emerging environmental pollutants, are increasingly detected in human musculoskeletal tissues, but their impact on osteoarthritis (OA) pathogenesis remains unclear. This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA.\n\nID: 41980172\nTitle: Polystyrene Microplastics Induced Hepatocytes Pyroptosis, Apoptosis and Ferroptosis via GSDMD-N-Mediated Mitochondrial Damage.\nAbstract: Microplastics (MPs), as emerging food contaminants, have been established to exert adverse effects on the liver. However, the precise toxicological mechanisms remain elusive. Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes. This study provided novel mechanistic insights into MPs-induced hepatotoxicity, identifying GSDMD-N as a potential central hub coordinating multiple cell death modalities.\n\nID: 41960285\nTitle: Micro- and nanoplastics influences in Parkinson's disease: lessons from human stem cell models.\nAbstract: Neuroinflammatory contributions play a critical role in Parkinson's disease onset and progression. Key drivers of neuroinflammation include glial cell reactivity, cytokine signaling, protein aggregation, and mitochondrial dysfunction. Although animal models have been extensively used to investigate the mechanisms, their translational relevance is limited because neuroinflammation in humans is typically chronic, heterogeneous, and sustained over years, whereas in rodents is often acute, transient, and resolves within days to weeks. This paper highlights the utility of human stem cell-derived models in studying Parkinson's disease by recapitulating patient-specific genetic mutations, neuroinflammatory microglia-neuron interactions, \u03b1-synuclein aggregation, and dopaminergic dysfunction, thereby enabling mechanistic studies in the human-relevant models. In addition, we examine how micro- and nanoplastics may exacerbate neuroinflammation in PD. This review concludes by highlighting how human-relevant stem cell-based approaches advance mechanistic understanding of Parkinson's disease.\n\nID: 41957923\nTitle: Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?\nAbstract: The enteric nervous system (ENS), a key component of the gut-brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)-a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or environmental contamination. Emerging evidence suggests that FCs may initiate or amplify neurodegenerative processes, yet their effects on the ENS and their impact in gut-to-brain communication remain insufficiently characterized. This systematic review synthesizes current evidence on FCs-induced effects on the ENS and its involvement in mediating neurotoxicity from dietary toxicants exposure. Following PRISMA guidelines, 67 studies were included pertaining to cellular or mammalian experimental models exposed to FCs via enteral routes, reporting ENS-related outcomes or studying vagal involvement in modulating FC toxicity. The main FCs evaluated were pesticides, toxins, bisphenols, acrylamide, manganese, and micro-/nanoplastics. Across studies, FCs consistently induced neurochemical remodeling of the ENS, activation of enteric glia, often coupled with intestinal alterations. Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain. Vagotomy models confirmed that disrupting ENS-CNS communication attenuates FC-related central neurotoxicity, supporting the involvement of food toxicants in gut-to-brain propagation of neurotoxic signals. These findings support the body-first hypothesis of PD and position the ENS as a critical, yet underinvestigated interface in exposome-related neurotoxicology. The review highlights research gaps and the need for improved models and long-term, low-dose studies reflecting realistic FC exposure.\n\nID: 41580402\nTitle: Micro-nanoplastics and Parkinson's disease: evidence and perspectives.\nAbstract: With the intensification of global plastic pollution, the potential threats posed by micro- and nanoplastics (MPs/NPs) to human health have become a major concern. MPs/NPs enter the organism through ingestion, inhalation, and skin contact, subsequently accumulating in multiple organs-particularly the brain. Increasing experimental and epidemiological evidence implicates MPs/NPs in the development of Parkinson's disease (PD). Preclinical research models indicate that MPs/NPs may accelerate both the initiation and progression of PD by facilitating \u03b1-synuclein misfolding and aggregation, triggering neuroinflammatory cascades, elevating oxidative stress, and impairing mitochondrial function. To further investigate the causal role of MPs/NPs in PD, upcoming studies should emphasize well-designed, large-scale prospective cohorts to assess individual exposure to plastic-related pollutants, elucidate the pathways of MPs/NPs into the central nervous system, establish safety thresholds for their neurotoxicity, explore the correlation between exposure levels and central nervous system accumulation, clarify the temporal relationship between MPs/NPs accumulation and PD pathology and symptom onset, and identify the neuropathological mechanisms triggered by relevant concentrations of MPs/NPs. Such data will be instrumental in informing preventive and potentially interventional strategies, while offering actionable insights into the interaction between MPs/NPs and PD.\n\nID: 41483106\nTitle: Hepatotoxic mechanisms of functionalized nanopolystyrene: decoding the role of ionic surface groups.\nAbstract: With annual global plastic production exceeding 400 million tons, nanoscale polystyrene particles (nPS) have become a major health concern due to their bioaccumulation capacity and ability to cross biological barriers. Surface-charged nPS variants (cationic, anionic, and neutral) show distinct biodistribution patterns, yet the mechanisms underlying their systemic damage remain incompletely understood. This study aimed to investigate the systemic injury mechanisms of nPS with different surface charges. Mice were exposed to fluorescently labeled cationic (amino-modified), anionic (carboxyl-modified), and neutral nPS via drinking water (25\u00a0mg/mL) for 3\u00a0weeks. Tissue distribution was analyzed using fluorescence microscopy; pathological changes were assessed via hematoxylin-eosin (HE) staining; metabolic perturbations were detected by metabolomic profiling. Mechanistic investigations were performed using metabolomics, flow cytometry, and molecular assays in AML12 hepatocytes and vascular endothelial cells. Fluorescence microscopy showed neutral nPS accumulated in the vascular endothelium of the stomach, intestine, and lung via passive diffusion, while cationic/anionic nPS penetrated hepatic sinusoids through charge-mediated interactions. HE staining revealed severe liver injury, with no significant abnormalities in other tissues. Metabolomic profiling indicated disrupted hepatic amino acid and lipid metabolism, depleted antioxidants (e.g., vitamin E and glutathione), and induced oxidative stress (evidenced by elevated hydroxy fatty acids). In hepatocytes, nPS-induced endoplasmic reticulum (ER) stress triggered excessive reactive oxygen species (ROS) production, inhibiting SLC7A11-mediated cystine uptake and glutathione synthesis, leading to disulfide stress (\u03b2-actin disulfide mispairing) and ferroptosis (GPX4 inactivation and iron accumulation). In contrast, neutral nPS induced endothelial cell senescence via phagolysosome dysfunction, causing lysosomal membrane permeabilization and \u03b2-galactosidase release. This study identifies a \"charge-specific injury\" paradigm: charged nPS induce hepatocyte ferroptosis via an ER stress-disulfide stress cascade, while neutral nPS trigger endothelial senescence through phagocytic dysfunction. These findings provide critical insights for the biosafety assessment of nanoplastics and identify potential targets for preventing plastic pollution-related liver diseases.\n\nID: 41483019\nTitle: Endocrine disruptors in aquatic environments: evaluating the toxicity of Bisphenol-A and diethyl phthalate.\nAbstract: Two endocrine disruptors (EDCs) commonly found polluting aquatic ecosystems have been analyzed in this study. Bisphenol-A (BPA) is one of the most potent endocrine disruptors used to synthesize poly-carbonate plastic for food and drink packages, as epoxy-resins in metal cans, sports, toys, and medical equipment and consumer electronics; whereas, the other is Phthalate [-diethyl phthalate (DEP)] that is found in cosmetics and personal care products. Euplotes crassus, an interstitial marine ciliate protozoan is a promising bioindicator for evaluating the toxicity of various aquatic environmental communities like sediments, fresh waters and waste waters. Euplotes crassus were used in our study to analyze the effect of BPA and DEP, identifying them as one of the major environmental pollutants in aquatic ecosystems. Our results demonstrate that widespread water contamination with BPA as well as phthalate causes potent cellular damage to this protozoan sentinel. Lethal and sublethal exposures of both these EDCs were found to cause extensive cellular damage affecting cell survival, replication rate, lysosomal membrane stability and endocytosis rate of Euplotes crassus at different doses and time intervals. Although cell death in Euplotes crassus was not that evident when treated with phthalate as opposed to BPA treatment and the protozoans survived at a higher levels of the dose of Phthalate; there was severe cellular and nuclear damage demonstrating that this EDC had a capacity of being more persistent and has a more deleterious effect in terms of biomagnification, indicating long-term harm, not only to the health of aquatic organisms but also to those at higher trophic levels that consume them as food.\n\nID: 41455227\nTitle: Arachidonic acid reverses microplastic-induced macrophage dysfunction in teleost fish.\nAbstract: Microplastic pollution poses a significant threat to aquaculture by compromising fish immunity, particularly macrophage function. This study investigated the impact of polystyrene microplastics (PS) on Nile tilapia (Oreochromis niloticus) macrophages and explored metabolic interventions to reverse PS-induced damage. PS exposure increased tilapia susceptibility to Streptococcus agalactiae infection, reducing fish survival. PS accumulated in head kidney macrophages, impairing phagocytosis, altering cytokine expression, elevating oxidative stress and malondialdehyde levels, and suppressing T-cell proliferation. Transcriptomics revealed PS dysregulated lysosomal pathways, reducing lysosomal membrane permeability and bacterial killing capacity. Metabolomic screening identified arachidonic acid (AA) as the most significantly suppressed metabolite in PS-exposed macrophages. Exogenous AA administration restored macrophage function including phagocytosis, cytokine expression, oxidative stress, enhanced lysosomal integrity, improved bactericidal activity, and increased survival during S. agalactiae challenge in PS-exposed fish. AA also reversed PS-induced transcriptional dysregulation of lysosomal genes. These results demonstrate that AA rectifies PS-induced macrophage dysfunction and lysosomal impairment, supporting its potential as a dietary supplement to mitigate microplastic immunotoxicity in aquaculture.\n\nID: 41357964\nTitle: Overall effects of microplastics on brain.\nAbstract: Microplastic (MP) and nanoplastic (NP) pollution represents a pervasive environmental issue, raising significant concerns regarding potential neurotoxicity and impacts on brain health. This review synthesizes recent research findings to provide a comprehensive overview of the effects of MPs/NPs on the brain. Evidence demonstrates that MPs/NPs can cross critical biological barriers, including the blood-brain barrier and the placenta, gaining access to the central nervous system (CNS) and the developing fetal brain, influenced by particle size, charge, and the biomolecular corona. Once present, MPs/NPs trigger multiple detrimental pathways, including oxidative stress, persistent neuroinflammation involving microglia and astrocytes, mitochondrial dysfunction leading to energy deficits, disruption of crucial neurotransmitter systems, and direct neuronal damage. Critically, NPs have been shown to promote the aggregation of proteins implicated in neurodegeneration, such as alpha-synuclein. These mechanistic disturbances translate into observable adverse outcomes in experimental models, ranging from cognitive impairments in learning and memory to behavioral abnormalities and pathologies resembling human neurodegenerative and neurodevelopmental disorders. Toxicity is modulated by particle characteristics, co-exposures, and host factors like age and sex, with indirect effects via the gut-brain axis also playing a significant role. While current evidence, primarily from animal models often using high doses, strongly indicates a neurotoxic potential, significant research gaps remain concerning human risk assessment under chronic, low-level environmental exposure conditions and the effects of environmentally aged, mixed-plastic particles. Future research should prioritize human studies, environmentally realistic exposure scenarios, and differentiating direct versus indirect neurotoxic mechanisms to accurately evaluate the threat MPs/NPs pose to human brain health.\n\nID: 41344183\nTitle: When nanoplastics (NPs) meet algae: Heteroaggregates exacerbate bioaccumulation, immunotoxicity, and microbial dysbiosis in the green mussel (Perna viridis).\nAbstract: Heteroaggregates (HAs) formed by nanoplastics (NPs) and microalgae occur ubiquitously in natural aquatic systems. However, their influence on the toxicokinetics and biological effects of NPs in marine mussels remains largely unknown. Here, the green mussels (Perna viridis) were exposed to NPs and HAs at their environmentally relevant concentrations for 21 d, followed by a 7-d depuration phase. The effects on toxicokinetics, immunological responses, and microbiota of digestive gland were evaluated. The results showed that HAs increased the uptake rate constant in digestive gland by 5.5-fold and tissue accumulation of NPs by 2.5-fold compared to NPs alone, resulting in higher NPs burdens after depuration. Meanwhile, HAs exacerbated NPs-induced immunotoxicity, including increased hemocyte mortality and ROS production, and decreased phagocytosis and lysosomal membrane stability. Moreover, HAs led to more pronounced dysbiosis of microbiota in digestive gland than NPs alone, reducing fungal diversity by 56\u202f% and enriching opportunistic fungal pathogens such as Fusarium, while bacterial communities showed minor shifts. This study has provided critical evidence that HAs act as a \"Trojan horse,\" exacerbating NPs risks. This study highlights the necessity of adding the naturally occurring HAs into the ecological risk assessment framework of NPs, especially for benthic filter-feeding organisms.\n\nID: 41274204\nTitle: Environmentally relevant concentrations of polystyrene nanoplastics induce Parkinson's-like neurotoxicity in C. elegans via oxidative stress.\nAbstract: This study reveals that environmentally relevant polystyrene nanoplastics (PS-NPs) induces Parkinson's disease (PD)-like pathology in Caenorhabditis elegans (C. elegans) through oxidative stress. Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions.\n\nID: 41252097\nTitle: Do microplastics play a role in the pathogenesis of neurodegenerative diseases? Shared pathophysiological pathways for Alzheimer's and Parkinson's disease.\nAbstract: The widespread presence of microplastics (MPs) in the environment has raised significant concerns about their potential impact on human health. As of 2023, the Ocean Conservancy estimates that adults may ingest up to 121,000 MPs annually. While the majority of these particles are cleared from the body, a small fraction can persist, as MPs are non-biodegradable and resist breakdown, posing long-term health risks that remain poorly understood. This review explores the emerging link between MP exposure and the development of neurodegenerative diseases, particularly Alzheimer's disease (AD) and Parkinson's disease [1]. MPs appear capable of triggering neurotoxic pathways, including activation of resident immune cells in the brain, oxidative stress, blood-brain barrier (BBB) disruption, mitochondrial dysfunction, and neuronal damage, which may contribute to neuroinflammation and disease progression. Specifically, six MP-related mechanistic pathways associated with AD were identified: BBB disruption, chronic inflammation, oxidative stress and ROS generation, mitochondrial dysfunction, impaired autophagy and proteostasis, and epigenetic alterations. Similarly, six pathways were implicated in PD: BBB disruption, oxidative stress in dopaminergic neurons, mitochondrial dysfunction, microglial-driven neuroinflammation, \u03b1-synuclein aggregation, and gut-brain axis [2] disruption. Ultimately, our findings underscore the urgent need for further research into the neurological consequences of chronic MP exposure in humans and highlight the importance of strengthening global policies to curb plastic pollution and mitigate its long-term health risks.\n\nID: 41218368\nTitle: Elevated blood microplastics and their potential association with Parkinson's disease.\nAbstract: Microplastic (MP) contamination in human blood and its potential link to Parkinson's disease (PD) remain poorly understood. In this study, we collected whole blood samples from 21 PD patients and 12 age- and sex-matched healthy controls under strict anticontamination protocols. A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs. Five polymer types-polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and nylon-66 (PA66)-were detected in the sample. The total MP burden was significantly greater in PD patients than in controls (21.36\u202f\u00b1\u202f8.42 vs. 13.56\u202f\u00b1\u202f5.92\u202f\u03bcg/g; p\u202f<\u202f0.01), with the greatest increases observed for PVC (1.49-fold), PP (2.74-fold) and PA66 (6.62-fold), whereas the PE and PS levels were not significantly different. LDIR and SEM analyses revealed diverse particle morphologies, with most polymers appearing as granular particles. In vitro assays further revealed that PVC and PP microplastics induced dopaminergic neuron apoptosis and increased the level of phosphorylated \u03b1-synuclein (p-\u03b1-syn), providing support for their potential neurotoxicity. Together, these findings indicate elevated blood MP levels in PD patients and offer preliminary evidence linking polymer exposure with PD-related neuronal vulnerability.\n\nID: 41196586\nTitle: Pathological Folding of \u03b1-Synuclein on Polystyrene Nanoplastic Revealed by Sum Frequency Scattering and 2D Infrared Spectroscopy.\nAbstract: The impact of micro- and nanoplastics (MNPs) on human health is a growing field of research. Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases.\n\nID: 41115925\nTitle: Dysfunctional digestive tract highlights the metabolic hallmarks of nanoplastic-exacerbated Parkinson's pathology.\nAbstract: Parkinson's disease (PD) is increasingly viewed as both a neurological and metabolic disorder, with the gut-brain axis playing a key role. This study explored how polystyrene (PS) nanoplastics contributed to PD progression by examining their metabolic impact in an A53T \u03b1-synuclein (\u03b1S) mouse model. Mice given PS nanoplastics orally (2\u2009mg/kg every other day for three months) displayed compromised gut barrier integrity, including a 30% drop in goblet cells and increased epithelial apoptosis in the ileum. Microbial diversity in the ileum rose sharply, with an overgrowth of Desulfovibrio spp. linked to neuroinflammation and \u03b1S aggregation. KEGG analysis confirmed apoptosis and lipopolysaccharide biosynthesis pathways influenced by nanoplastics, while metabolomics identified over 200 altered fecal metabolites, including those associated with cytochrome P450 activity and disruptions to cancer-related pathways. Additionally, histopathology revealed liver inflammation, underscoring the systemic effects of nanoplastic exposure. Overall, our findings suggest that environmental nanoplastics may aggravate PD physiopathology through gut-liver axis disruption and metabolic dysregulation.\n\nID: 40782538\nTitle: Polystyrene nanoplastics-induced methuosis in brain microvascular endothelial cells: Rescue via ESCRT membrane repair system.\nAbstract: Nanoplastic pollution has emerged as a significant environmental concern, with increasing evidence suggesting that these nanoparticles can disrupt the blood-brain barrier (BBB) and accumulate in the brain, ultimately leading to neurological impairment. However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution.\n\nID: 40701096\nTitle: Unveil new insights into microplastic and benzo[a]pyrene toxicity in the seaworm Hediste diversicolor coelomic fluid: A transdisciplinary approach.\nAbstract: Microplastics (MPs) pollution presents a pressing concern for marine ecosystems, as their small size facilitates both ingestion and accumulation by organisms, as well as the transport of harmful pollutants. This dual threat complicates their ecological impact, especially concerning compartments like the coelomic fluid, crucial for marine invertebrate physiology. In this study, we investigated the toxicological effects of environmentally relevant concentrations of MPs (10 and 50\u202fmg/kg sediment), both alone and in combination with benzo[a]pyrene (B[a]P, 1\u202f\u00b5g/kg sediment), a carcinogenic polycyclic aromatic hydrocarbon known for its genotoxic and pro-apoptotic properties. The benthic polychaete Hediste diversicolor was exposed to these treatments for 7 days through spiked sediments, simulating realistic environmental conditions. The MPs used were particles smaller than 30\u202f\u00b5m, composed of a mixture of polymers, including PE, PET, PP, LDPE, HDPE, and PEVA, with varied morphologies such as fragments, fibers, and films. Analyses revealed that both MPs and B[a]P were internalized by coelomocytes, with MPs enhancing B[a]P bioaccumulation. Combined exposures led to marked cytotoxic and genotoxic effects, evidenced by decreased lysosomal membrane stability (LMS), elevated micronuclei frequency (FMN), and increased DNA fragmentation, as assessed by terminal dUTP nick-end labeling (TUNEL) assay. Co-exposure also altered apoptotic and DNA repair pathways, as demonstrated by upregulation of P53, Bax, and Casp-3, alongside downregulation of the anti-apoptotic marker Bcl-2. These findings suggest that co-exposure intensifies cellular damage and apoptotic signaling. Overall, this study underscores the risks of MPs in marine ecosystems, particularly their role in accumulating and transferring harmful substances affecting biota health.\n\nID: 40615601\nTitle: Physiological and cellular responses of Manila clam Ruditapes philippinarum exposed to different shapes and sizes of polyethylene terephthalate microplastics.\nAbstract: Microplastics (MPs) are ubiquitous in marine environments and have become a major source of environmental pollution. Although fragmented and fibrous MPs are the most abundant shapes in marine environment, studies on shape- and size-dependent MP toxicity in marine benthic bivalves remain limited. In this study, we aimed to evaluate the chronic effects of different shapes and sizes of polyethylene terephthalate (PET) MPs on Manila clam Ruditapes philippinarum, and investigate their physiological and cellular responses. The mortality of R. philippinarum showed no changes at all concentrations of fragmented and fibrous MPs. The respiration rate of R. philippinarum induced by large fragmented MPs was recovered to the control level at 6\u2009h, however, fibrous MPs significantly decreased compared to the control. In particular, fibrous MPs significantly increased and decreased filtration rate and lysosomal membrane stability, respectively, whereas the fragmented MPs showed no significant differences. These results enhance our understanding of the potential toxicological risks posed by MPs of various shapes and sizes to benthic organisms in marine environment.\n\nID: 40532836\nTitle: PPAR\u03b3 mediated lysosomal membrane permeabilization and lipophagy blockage were involved in microplastics and di (2-ethylhexyl) phthalate co-exposure induced immature testis injury.\nAbstract: Polystyrene microplastics (PS-MPs) and di (2-ethylhexyl) phthalate (DEHP), two main composites of plastic products, are always exposed to human at the same time. However, most existing research has focused on single exposure, which is not consistent with the actual exposure circumstance. In this study, single and co-exposure animal model were established. C57/BL6J mice were exposed to corn oil, 20\u00a0mg/kg PS-MPs, 200\u00a0mg/kg DEHP and PS-MPs\u00a0+\u00a0DEHP for 28 days. The HE staining showed more serious seminiferous epithelium disorganization in co-exposed mice, indicating that PS-MPs and DEHP co-exposure could aggravate testicular injury. Compared with control group, integrative analysis of transcriptomics and proteomics revealed that PPAR\u03b3 pathway played a crucial role in PS-MPs and DEHP co-exposure induced testis injury. In vitro, spermatocytes (GC-2) and leydig cells (TM3) were exposed to 50\u00a0\u03bcM MEHP, 10\u00a0mg/L PS-MPs and PS-MPs\u00a0+\u00a0MEHP for 48\u00a0h. Though PS-MPs and MEHP single exposure also triggered oxidative stress and PPAR pathway, the protein levels showed more remarkable difference in co-exposure group. Furthermore, co-exposure to PS-MPs and MEHP induced lysosomal membrane permeabilization (LMP), which significantly impaired lysosomal-mediated lipid degradation, thereby exacerbating lipid metabolism dysfunction in testicular cells. Treatment with N-Acetylcysteine (NAC) and knockdown of fatty acid-binding protein (FABP4) restored lipophagy flux and reduced lipid droplets deposition. Overall, co-exposure of PS-MPs and DEHP has synergistic toxic effect, inducing oxidative stress, PPAR\u03b3 activation and lipophagy blockage, finally resulting in unbalanced lipid metabolism and testicular damage.\n\nID: 40459174\nTitle: Plastamination: A Rising Concern for Parkinson's Disease.\nAbstract: \n\nID: 40317414\nTitle: Carnosic Acid Attenuated the Motor Impairment by Bisphenol A is Related to the Regulation of Autophagy Through Parkin in In Vitro and In Vivo.\nAbstract: Bisphenol A (BPA) is an endocrine-disrupting compound linked to impairments in motor function and the manifestation of anxiety-like behaviors. The present study investigated the effects of carnosic acid (CA) on BPA-induced motor deficits and explored the role of parkin in the autophagic mechanism. First, C57BL/6\u00a0J male mice were orally administered with CA (5\u00a0mg/kg and 20\u00a0mg/kg) or RE (80\u00a0mg/kg rosemary extract) to test the motor function and anxiety-like behaviors in BPA (50\u00a0\u03bcg/kg) treatment. The results showed that CA and RE ameliorate BPA-induced motor impairments and anxiety-like behaviors. Moreover, CA and RE attenuated BPA-induced phosphorylation of tau and \u03b1-synuclein while restoring the expression levels of autophagy-related proteins, including parkin, PINK1, PI3K, Atg7, Beclin1, and LC3B-II. Then, SH-SY5Y cells were treated with 20\u00a0nM BPA and 1\u00a0\u03bcM CA or 0.5\u00a0\u03bcg/mL RE for 18\u00a0h. The results showed that treatment of CA and RE with BPA activated the parkin pathway and reduced the levels of Ser396p-tau and p-\u03b1-synuclein. Moreover, treatment of CA or RE with BPA restored the parkin signaling, resulting in the upregulation of autophagy-related proteins. However, wortmannin treatment attenuated this restorative effect of CA or RE. Additionally, transfection with parkin siRNA in cells reversed the ability of CA or RE to counteract BPA-induced reductions in autophagy-related proteins and increased the accumulation of misfolded proteins. Therefore, the results indicated that CA and RE improved motor impairments and reduced the accumulation of misfolding proteins induced by BPA, potentially through regulating autophagy by parkin.\n\nID: 39883073\nTitle: Polystyrene Nanoplastics Hitch-Hike the Gut-Brain Axis to Exacerbate Parkinson's Pathology.\nAbstract: The neurological implications of micro- and nanoplastic exposure have recently come under scrutiny due to the environmental prevalence of these synthetic materials. Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of \u03b1 synuclein (\u03b1S) via the enteric nervous system, or the so-called gut-brain axis. Here we first examined the effect of enteric exposure to polystyrene nanoplastics on the peripheral and central pathogenesis of A53T, a representative \u03b1S mutant. Specifically, the polystyrene nanoplastics accelerated the amyloid aggregation of A53T \u03b1S, which subsequently elevated the in vitro production of glial activation biomarkers, cytokines, and reactive oxygen species and compromised mitochondrial and lysosomal membrane integrity, further shifting cellular metabolite profiles in association with PD pathophysiology. In vivo, coadministration of the polystyrene nanoplastics and A53T \u03b1S facilitated their synergistic gut-to-brain transmission in mice, leading to progressive impairment of physical and motor skills in resemblance to characteristic PD symptoms. This study provides insights into the response and vulnerability of Parkinson's gut-brain axis to polystyrene nanoplastics.\n\nID: 39853018\nTitle: Polystyrene Nanoplastics Elicit Multiple Responses in Immune Cells of the Eisenia fetida (Savigny, 1826).\nAbstract: The improper disposal of plastic products/wastes can lead to the release of nanoplastics (NPs) into environmental media, especially soil. Nevertheless, their toxicity mechanisms in soil invertebrates remain unclear. This study investigated the impact of polystyrene NPs on Eisenia fetida (Savigny, 1826) immune cells, focusing on oxidative stress, immune responses, apoptosis, and necrosis. Results showed that 100 nm NPs were internalized into the cells, causing cytotoxicity. NPs were observed to inhibit cell viability by increasing reactive oxygen species, decreasing the levels of antioxidants (e.g., superoxide dismutase, catalase, and glutathione), and inducing lipid peroxidation and DNA oxidation. Additionally, assays on neutral red retention time, lysozyme activity, and Ca2\u207a levels demonstrated that NPs resulted in a loss of lysosomal membrane stability and a reduction in immune resistance. The depolarization of the mitochondrial membrane potential and the results of the apoptosis assays confirmed that the NPs induced the onset of early apoptosis. The difficulty of the NP in causing cell death by disrupting the plasma membrane was demonstrated by the results of the lactate dehydrogenase release assays in relation to cell necrosis. This research provides cellular-level insights into the ecological risks of NP exposure on soil fauna.\n\nID: 39850110\nTitle: Trans-sodium crocetinate ameliorates Parkinson-like disease caused by bisphenol A through inhibition of apoptosis and reduction of \u03b1-synuclein in rats.\nAbstract: Trans-sodium crocetinate (TSC) is one of the crocetin derivations that is more soluble and stable than crocetin and its cis form. It easily crosses the blood-brain barrier. TSC has neuroprotective effects. Bisphenol A (BPA) is an endocrine-mimicking compound that induces Parkinson-like disease by impacting the dopaminergic system. In this research, the effects of TSCs on BPA-induced Parkinson-like symptoms via behavioral and molecular assays have been investigated. Male Wistar rats received BPA (75 mg/kg, gavage), TSC (10, 20, and 40 mg/kg), and levodopa (L-dopa) (10 mg/kg) via intraperitoneal injection (IP) for 28 days. Parkinsonian-like motor features were evaluated using bar test, rotarod, and open field experiments. Malondialdehyde (MDA) and glutathione (GSH) levels were also measured as the most important indicators of oxidative stress. Western blotting was performed for the molecular assays of alpha-synuclein (\u03b1-syn), Bcl-2, Bax, caspase-3, Beclin, and LC3 I/II proteins. Our analyses indicated that treatment with TSC at high dose reduces MDA levels and protects GSH reserves. TSC can also increase anti-apoptotic Bcl-2 and decrease pro-apoptotic Bax and caspase-3 proteins. While it does not affect autophagy markers, TSC decreased \u03b1-syn protein expression, reduced the catalepsy time, and improved the time spent staying on the rotating bar and the locomotor activity. Overall, TSC likely ameliorates BPA-mediated Parkinson' s-like symptoms by suppressing oxidative stress inhibition. This leads to reduced \u03b1-syn expression, which ultimately results in apoptosis inductions. Therefore, TSC can serve as a promising exploratory target for future research aimed at controlling Parkinson's disease.\n\nID: 39740740\nTitle: Nano-sized polystyrene plastics toxicity: Necroptosis pathway caused by autophagy blockade and lysosomal dysfunction.\nAbstract: The persistent detection of nano-sized plastic particles in humans, animals, and animal-derived products underscores the potential impact of these particles on living organisms. Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP. SYNOPSIS: The cytotoxicity and its related mechanisms of nano-plastic is still unclear. This study found that nano-plastics may induce necroptosis in cells, and autophagy blockade and lysosomal dysfunction are prodromal manifestations.\n\nID: 39441179\nTitle: Exploring the Interaction of Human \u03b1-Synuclein with Polyethylene Nanoplastics: Insights from Computational Modeling and Experimental Corroboration.\nAbstract: Plastics, particularly microplastics (MPs) and nanoplastics (NP), have become major environmental and health concerns due to their high chemical stability. The highly hydrophobic plastics enter living organisms through reversible interactions with biomolecules, forming biocoronas. Following recent reports on plastics breaching the blood-brain barrier, the binding behavior of human \u03b1-synuclein (h\u03b1Sn) with polyethylene-based (PE) plastics was evaluated by using molecular dynamics simulations and experimental methods. The results provided three important findings: (i) h\u03b1Sn transitions from an open helical to a compact conformation, enhancing intramolecular interactions, (ii) nonoxidized PE NPs (NPnonox) rapidly adsorb h\u03b1Sn, as supported by experimental data from dynamic light scattering and adsorption isotherms, altering its structure, and (iii) the oxidized NP (NPox) failed to capture h\u03b1Sn. These interactions were dominated by the N-terminal domain of h\u03b1Sn, with major contributions from hydrophobic amino acids. These findings raise concerns about the potential pharmacological effects of NP-protein interactions on human health.\n\nID: 39079648\nTitle: Assessing the presence of microplastic in agriculture soils irrigated with treated waste waters using Lumbricus sp.: Ecotoxicological effects.\nAbstract: Global water scarcity entailed the use of treated wastewater (TWW) in agriculture, however, this water can vehiculate numerous pollutants into soil and further crops such as microplastics (MPs). To date, few studies had quantified the accumulation of MPs in soils and earthworms after irrigation with TWW as well as their toxicological effects. Hence, the main objective of the present work is to evaluate the toxicity of MPs using Lumbricus sp. earthworms collected from TWW irrigated soils with an increasing gradient of time (5\u00a0years, 16\u00a0years and 24\u00a0years). MPs determination in soil, as well as in earthworms were performed. The intestinal mucus was quantified, and cytotoxicity (Lysosomal membrane stability (LMS), Catalase (CAT) and glutathione-S-Transferase (GST) activities), neurotoxicity (Acetylcholinesterase activity (AChE)) and genotoxicity (Micronuclei frequency (MNi)) biomarker were assessed. Our results revealed that the use of TWW rendered MPs accumulation in earthworms' tissues and induce alteration on the intestinal mucus. An important cytotoxicity time-depending was observed being associated with an increase on genotoxicity. Overall, the present investigation highlights the ecotoxicological risk associated with the use of TWWs as an important driver of MPs and consequently measures are necessary to reduce MPs in wastewater treatment plans to improve this non-conventional water quality.\n\nID: 38885454\nTitle: Insights into the Binding Interactions between Microplastics and Human \u03b1-Synuclein Protein by Multispectroscopic Investigations and Amyloidogenic Oligomer Formation.\nAbstract: Aggregation of human \u03b1-synuclein protein is regarded to be a key stage in the etiology of Parkinson's disease and numerous other neurodegenerative illnesses. Microplastics pollution can be a potential agent to promote various neurodegenerative disorders. In this study, we have employed various multispectroscopic analytical methods to investigate the binding interactions between polyethylene (PE-MPs), polyvinyl chloride (PVC-MPs), polystyrene (PS-MPs) microplastics, and human \u03b1-synuclein protein. Spectroscopic investigations using UV-vis absorption, circular dichroism, and Fourier transform infrared have indicated different alterations in \u03b1-synuclein protein's secondary structures induced by the formation of the \u03b1-synuclein protein-MP binding complex. This study suggests that PS-MPs are found to be the most effective microplastic that promote amyloidogenic oligomer emergence because of their tiny size (100 nm).\n\nID: 42400323\nTitle: A PARK9 iPSC-Derived Dopaminergic Neuron Model Enables Drug Screening Targeting Autophagy-Lysosome Pathway Dysfunction in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disease characterized by dopaminergic neuronal degeneration in the substantia nigra, in which lysosomal dysfunction and impaired autophagy-lysosome pathway activity are increasingly recognized as important pathogenic mechanisms. However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes.\n\nID: 42395216\nTitle: Human Exposure to Micro- and Nanoplastics and Their Potential Neurological Implications: A Systematic Review of Emerging Evidence.\nAbstract: The growing prevalence of micro- and nanoplastics (MNPs) in the environment elicits concerns about their possible impact on human neurological health. Although studies on animals have suggested neurotoxic effects, evidence from humans is still scarce. This systematic review gathers existing human data to assess the presence, types, detection techniques, and neurological consequences of MNPs in different biological matrices. A comprehensive review was performed on peer-reviewed research concentrating on human studies that report the detection of MNPs in biological tissues and fluids. Four qualifying studies were identified: one clinical observational study, two cadaveric analyses, and one quasi-experimental trial. The data collected encompassed demographics, detection methods, types and concentrations of polymers, biological matrices examined, and neurological biomarkers. MNPs were observed in cerebrospinal fluid (CSF), faeces, urine, olfactory bulbs (OBs), and in brain, liver, and kidney tissues from postmortem cases. The polymers that were reported most frequently were polyethylene (PE) and polypropylene (PP). The detection methods included micro-Fourier transform infrared spectroscopy (\u00b5FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Although the available evidence is limited, emerging findings indicate the possible accumulation of MNPs in the human central nervous system (CNS), particularly in individuals with dementia or compromised blood-brain barrier (BBB) integrity. Relationships were noted between MNP exposure and disruptions in the BBB, inflammatory markers, and alterations in the gut-brain axis. This review consolidates the findings and emphasizes the need for further exploration of human exposure to MNPs and their possible accumulation in neural tissues. Although there is variability in methodologies used in the reviewed articles, PE and PP stand out as the primary polymers of concern. While a direct causal relationship cannot yet be confirmed, the results highlight the necessity for improved detection methods, larger sample sizes, and long-term studies to better understand the impact of MNPs on neuroinflammation and neurodegeneration.\n\nID: 42389431\nTitle: Protein kinase B is involved in bisphenol A-induced macrophage polarization through mechanistic target of rapamycin-dependent autophagy.\nAbstract: \n\nID: 42378827\nTitle: GBA mutation exacerbates \u03b1-synuclein pathology with involvement of ROS and p38 MAPK signaling in Parkinson's disease.\nAbstract: The glucocerebrosidase (GBA) gene is the second most significant genetic risk factor for Parkinson's disease (PD) pathogenesis. Notably, GBA mutations not only enhance PD susceptibility in the general population but also accelerate disease progression. Nevertheless, the precise molecular mechanisms underlying GBA-associated PD pathogenesis remain elusive. In this study, we demonstrated that the L444P mutation in GBA significantly impairs the enzymatic activity of its encoded protein, glucocerebrosidase (GCase). It caused lysosomal dysfunction and increased \u03b1-synuclein (\u03b1-syn) expression and aggregation induced by \u03b1-syn preformed fibril (PFF). Mechanistically, our data revealed that the L444P GBA mutation increased reactive oxygen species (ROS) levels associated with activation of the p38 MAPK signaling pathway. Importantly, pharmacological inhibition of p38 MAPK pathway can change consistent with altered autophagic degradation and reduce PFF-induced \u03b1-syn aggregation, which is exacerbated by the L444P GBA mutation. These findings suggest that inhibiting p38 signaling provides a mechanistic rationale for targeting this pathway in GBA-associated PD.\n\nID: 42370616\nTitle: LRRK2 mutations: at the crossroads of dopamine, iron, and calcium imbalance in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons. The G2019S mutation in the leucine\u2011rich repeat kinase 2 (LRRK2) gene is the most common genetic cause of familial and sporadic PD. In dopaminergic neurons, increased kinase activity caused by LRRK2\u2011G2019S mutation impairs synaptic vesicle recycling and dopamine storage, increasing cytosolic dopamine, which is prone to oxidation and generates reactive oxygen species. Simultaneously, the mutation alters iron metabolism through Rab misregulation, increasing iron uptake and lysosomal dysfunction, further amplifying oxidative stress and creating a pro\u2011ferroptotic environment. At the same time, dysregulated calcium signaling, driven by the enhanced activity of L\u2011type calcium channels and impaired mitochondrial calcium buffering via the mitochondrial calcium uniporter, enhances mitochondrial dysfunction. This minireview integrates current evidence linking LRRK2\u2011G2019S to these pathological pathways, highlighting this mutation's role in dopamine, iron, and calcium imbalance. Understanding this molecular interplay may provide novel insights into PD pathogenesis and guide the development of targeted neuroprotective therapies.\n\nID: 42356279\nTitle: Oral Administration of Polyethylene Microplastics Induces BPA-Associated Antioxidant Activation and Synaptic-Related Transcriptional Responses in the Rat Prefrontal Cortex.\nAbstract: Background/Objectives: The pervasive presence of microplastics (MPs) and plastic-associated chemicals has raised concerns regarding their potential effects on the central nervous system. Polyethylene (PE), widely used in food-contact materials, can carry bisphenol A (BPA), an endocrine disruptor with oxidative and neuroactive properties. Although both MPs and BPA can cross biological barriers, their acute effects on the prefrontal cortex (PFC) remain poorly understood. The aim of the study was to evaluate the acute impact of orally administered free BPA, free MPs, and BPA adsorbed onto PE MPs (PE-BPA) on oxidative stress, inflammation, and gene expression in the PFC of Wistar rats. Animals received a single dose of BPA, PE-BPA, PE alone, or vehicle. Methods: Biochemical and transcriptional analyses were performed to evaluate the antioxidant and inflammatory responses as well as the potential changes in synaptic-related gene expression. Results: BPA-containing treatments produced selective early molecular responses. Catalase (CAT) and glutathione S-transferase (GST) activities were significantly increased in the PE-BPA group, with GST being also elevated in the BPA-alone group, whereas superoxide dismutase (SOD), myeloperoxidase (MPO), and malondialdehyde (MDA) levels did not significantly change. Transcriptional analyses revealed upregulation of the antioxidant genes Nrf2 and CAT in the PE-BPA group. Co-exposure to BPA and MPs also altered synaptic markers, including decreased brain-derived neurotrophic factor (BDNF) and Sert along with increased Nr2A expression, while inflammatory gene expression remained unaffected. Conclusions: These findings indicate that acute co-exposure to BPA and PE microplastics elicits early antioxidant activation and selective synaptic-related transcriptional changes in the PFC, suggesting that MPs may modulate BPA-associated molecular responses in the brain.\n\nID: 42353071\nTitle: Wolffia globosa Ethanolic Extract Protects Against Bisphenol A-Induced Osteoblast Dysfunction via Antioxidant Defense, Apoptosis Inhibition, and \u03b2-Catenin Modulation.\nAbstract: The prevalent endocrine disruptor bisphenol A (BPA) is associated with aging-related conditions, including metabolic disorders. It has been shown that BPA promotes bone fragility through oxidative stress-induced apoptosis and impaired osteoblast differentiation. The identification of sustainable bioactive substances that alleviate BPA-induced bone toxicity is thus of biomedical and environmental significance. Wolffia globosa (WG), the world's smallest flowering aquatic plant, has recently gained attention as a high-protein, antioxidant-rich nutraceutical, yet its impact on BPA-induced osteoblast dysfunction has not been systematically investigated. This study presents a comprehensive assessment of WG ethanolic extract (WGE) in MC3T3-E1 pre-osteoblasts, incorporating thorough phytochemical characterization, acute high-dose and chronic low-dose BPA exposure models, and multi-faceted mechanistic analysis. LC-MS/MS profiling identified luteolin (116.17 \u00b1 0.69 \u00b5g/g), rosmarinic acid (54.80 \u00b1 2.12 \u00b5g/g), and apigenin (48.77 \u00b1 0.61 \u00b5g/g) as the predominant bioactive compounds. WGE exhibited potent antioxidant capacity across DPPH and ABTS radical scavenging assays, complemented by high ORAC and FRAP values, reflecting broad-spectrum antioxidant mechanisms. Treatment with WGE (25 and 50 \u00b5g/mL) resulted in significant alleviation of BPA-induced cytotoxicity, decreased intracellular ROS levels, and inhibited apoptosis. WGE (12.5 \u00b5g/mL) also modulated autophagy-related markers (LC3-II, Beclin-1, and p62), suggesting potential autophagic participation, although flux verification was not conducted. Treatment with WGE (12.5 \u00b5g/mL) also restored BPA-suppressed osteogenesis under chronic exposure, as evidenced by enhanced alkaline phosphatase activity, and increased both mineralization and upregulation of osteogenic genes including runt-related transcription factor2 (Runx2), collagen type I alpha 1 (Colla1), alkaline phosphatase (ALP), and osteocalcin (OCN). These effects were accompanied by partial reactivation of Wnt/\u03b2-catenin signaling. This study is the first to demonstrate that WGE protects osteoblasts from BPA toxicity by concurrently strengthening antioxidant defenses, limiting apoptosis, modulating autophagy-related markers, and supporting \u03b2-catenin-mediated osteogenesis, highlighting WG as a promising sustainable nutraceutical candidate for the prevention of environmental toxin-related bone fragility.\n\nID: 42349722\nTitle: From plastics to pathology: The neurodegenerative impact of Bisphenol-A on Alzheimer's disease.\nAbstract: Bisphenol-A (BPA), a ubiquitous component of polycarbonate plastics and epoxy resins, has emerged as a significant environmental risk factor for neurodegenerative diseases, particularly Alzheimer's disease (AD). It is widely detected in the environment and humans due to its extensive use in plastics and epoxy resins for consumer products such as bottles, containers, and tableware. This review synthesizes current evidence on the molecular and cellular mechanisms by which BPA exposure may contribute to neurotoxicity and AD pathogenesis. We discuss how BPA disrupts endocrine signalling, induces oxidative stress, promotes neuroinflammation, and impairs synaptic plasticity, all of which are implicated in the development and progression of AD. The review also examines the impact of BPA on amyloid-beta accumulation, tau pathology, and cognitive decline, integrating findings from animal models, in vitro studies, and epidemiological research. Furthermore, we address the limitations of BPA alternatives and highlight emerging therapeutic and preventive strategies. This study highlights the pathogenic molecular mechanisms involved, offering a foundation for understanding BPA-induced neurodegenerative processes. By bridging the gap between environmental exposure and neuropathology, this article underscores the urgent need for regulatory action and further research to mitigate the neurodegenerative risks associated with BPA in plastics.\n\nID: 42320376\nTitle: Kefir peptides attenuate intestinal injury induced by combined exposure to microplastics and particulate matter.\nAbstract: Microplastics (MP) and particulate matter (PM) are pervasive environmental contaminants that pose significant threats to intestinal homeostasis. This study systematically investigated the individual and combined effects of MP and PM on intestinal injury using complementary in vivo and in vitro models. In mice, co-exposure to MP and PM induced pronounced oxidative stress, intestinal inflammation, disruption of epithelial barrier integrity, mucin accumulation, activation of endoplasmic reticulum (ER) stress, and dysregulation of autophagy. Consistently, in C2BBe1 intestinal epithelial cells, combined exposure significantly reduced cell viability and exacerbated oxidative stress, ER stress, and autophagic imbalance, as evidenced by increased reactive oxygen species (ROS), elevated BiP and ATF6 expression, and accumulation of p62 and LC3B-II. Moreover, co-exposure promoted intestinal inflammation, barrier dysfunction, and mucin accumulation, demonstrated by increased ICAM-1, IL-1\u03b2, IL-6, and TNF\u03b1 levels, reduced ZO-1 expression, and upregulated MUC2 expression. Strikingly, combined exposure-induced mucin accumulation may provide physical protection and compensate for barrier disruption. Notably, pretreatment with kefir peptides (KPs) markedly attenuated these deleterious effects in vivo and in vitro, supporting their protective potential. KPs pretreatment alleviated cytotoxicity by reducing oxidative and ER stress markers and normalizing autophagy-related protein expression. In addition, KPs decreased ICAM-1 levels, restored epithelial barrier integrity, and limited mucin accumulation in intestinal cells. Collectively, these findings demonstrate that concurrent exposure to MP and PM exacerbates intestinal injury through coordinated activation of oxidative stress, ER stress, and dysregulated autophagy pathways, and identify KPs as a promising preventive strategy for mitigating pollutant-induced intestinal damage.\n\nID: 42307976\nTitle: Personalized Pathogenic Nanoplastic Coronas Orchestrate Efferocytosis-Driven Immune Evasion in Lung Adenocarcinoma.\nAbstract: Airborne nanoplastic (NP) pollution is an emerging threat to respiratory health. Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern.\n\nID: 42297369\nTitle: Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary-Focused Studies.\nAbstract: Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine-disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE have been introduced as alternatives, raising concerns about their potential toxicity. This review examines the effects of BPA and its analogs on ovarian structure and function based on experimental rodent studies. Evidence indicates that BPA exposure leads to histopathological changes, including reduced follicle numbers, increased follicular atresia, and granulosa cell degeneration, along with alterations in reproductive hormones such as estrogen, progesterone, LH, and FSH. At the cellular level, bisphenol exposure is associated with oxidative stress, mitochondrial dysfunction, and impaired antioxidant defenses, which may trigger apoptosis and autophagy in granulosa cells and affect follicular development and oocyte quality. Overall, these findings indicate that bisphenol analogs may not represent safer alternatives.\n\nID: 42294809\nTitle: Microplastics-Induced Gut Microbiota Dysbiosis Accelerates Alzheimer's-Like Pathology and Cognitive Decline via the Gut-Brain Axis.\nAbstract: Alzheimer's disease (AD) is incurable and increasingly attributed to gene-environment interactions. Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration.\n\nID: 42294509\nTitle: Kelulut honey (Heterotrigona itama) as a multi-target neuroprotective strategy against bisphenol A-induced neurotoxicity.\nAbstract: Bisphenol A (BPA) is a synthetic chemical widely used in the production of plastics and epoxy resins due to its low cost, durability, and heat resistance.Recognised as an endocrine-disrupting chemical, BPA has raised growing concern regarding its potential effects on brain development, particularly during prenatal and early postnatal life. BPA-induced neurotoxicity involves multiple interconnected mechanisms, including oxidative stress, neuroinflammation, mitochondrial dysfunction, synaptic impairment, and neuroendocrine disruption, which collectively contribute to cognitive and behavioural abnormalities. Kelulut honey, produced by stingless bees (Heterotrigona itama), contains various bioactive compounds such as polyphenols, flavonoids, organic acids, and trehalulose. These compounds possess antioxidant, anti-inflammatory, and neuroprotective properties and may modulate pathways involved in neuronal survival, synaptic plasticity, inflammatory regulation, NMDA receptor signalling, and estrogen-related pathways. This narrative review summarises current findings on the neuroprotective potential of kelulut honey against BPA-induced neurotoxicity, highlights existing research gaps, and discusses future directions for further mechanistic and translational studies.\n\nID: 42280768\nTitle: Structure-Based Identification of Allosteric Glucocerebrosidase Stabilizers from Xylia xylocarpa (Roxb.) Taub. for Parkinson's Disease Using LC-MS Profiling and Computational Analysis.\nAbstract: Parkinson's disease is strongly linked to lysosomal dysfunction, particularly reduced activity of glucocerebrosidase (GCase) encoded by the GBA1 gene. Stabilizing GCase using small-molecule modulators represents a promising therapeutic strategy. In this study, phytochemicals from Xylia xylocarpa (Roxb.) Taub., a medicinal plant with reported neuroprotective potential, were profiled using LC-QTOF-MS and evaluated as GCase stabilizers through an integrated computational approach. LC-MS analysis in positive and negative modes tentatively identified 19 metabolites, of which 13 low-molecular-weight compounds (<500 Da) were selected for molecular docking against human GCase. Docking revealed six compounds with higher predicted binding affinity than the reference activator Pyrrolopyrazine. Pharmacokinetic screening based on Lipinski's rule of five and ADMET predictions identified Senbusine A as a viable lead candidate. It exhibited favorable binding interactions, forming stabilizing contacts within a non-catalytic inter-monomer interface associated with structural modulation of GCase. PASS analysis suggested a high probability of neuroactive properties. Molecular dynamics simulations (200 ns) confirmed stable binding and reduced conformational fluctuations compared to apo and control systems. Overall, computational predictions identify Senbusine A as a potential pharmacological chaperone-like stabilizer of GCase, exhibiting a favorable pharmacological profile and warranting further experimental validation.\n\nID: 42276620\nTitle: Invisible threats of microplastics induced toxicity: Oxidative and inflammatory pathways in the CNS and retina.\nAbstract: The global spread of microplastics has become a serious public health concern. Once thought to be inert, microplastics are now recognized as biologically active agents capable of accumulating in the body and causing toxic effects across organ systems. This review summarizes current evidence on their oxidative and inflammatory effects in the central nervous system (CNS) and the eye. Studies show that microplastics can cross biological barriers such as the blood-brain barrier (BBB) and blood-retinal barrier (BRB), where they are taken up by cells, impair mitochondria, and trigger inflammation. Microplastics have been found in cerebrospinal fluid, brain tissue, and ocular structures, raising concern about their link to neurodegenerative and retinal diseases, including Alzheimer's, Parkinson's, macular degeneration, and other disorders. Mechanistic data indicate activation of NF-\u03baB and TGF-\u03b21 pathways, promotion of protein aggregation, and disruption of neural signaling. In the eye, microplastics have been linked to oxidative stress, corneal thinning, and photoreceptor damage. However, human studies are limited due to challenges in detecting tiny particles and lack of microplastic-free controls. Research is further hindered by inconsistent definitions, particle diversity, and non-physiological exposure models. We highlight the need for standardized methods, multi-omics tools, and long-term studies to better understand exposure impacts. Given the rise in neurological and ocular diseases, clarifying the role of microplastics is essential for effective public health strategies.\n\nID: 42272075\nTitle: Rare-Variant Burden across Lysosomal Genes Implicates Sialylation and Ganglioside Metabolism in Parkinson's Disease.\nAbstract: Lysosomal dysfunction is central to Parkinson's disease (PD) pathogenesis, with GBA1 representing the strongest established genetic risk factor. Numerous other genes involved in lysosomal sphingolipid, glycosphingolipid, and ceramide metabolism have been proposed as contributors to PD, highlighting the need for genetic analyses across these pathways. The aim was to evaluate the contribution of rare variants across lysosomal genes to PD risk. We analyzed rare variants (minor allele frequency\u2009\u22640.01) across 36 lysosomal genes in 8267 individuals with PD and 68,208 controls, including 793 early-onset PD (\u226450\u2009years) cases. Targeted sequencing was performed in four cohorts at McGill University (3456 cases and 2664 controls) and combined with whole-genome sequencing data from the United Kingdom (UK) Biobank (2848 cases, 62,451 controls) and the Accelerating Medicines Partnership-PD cohort (1963 cases, 3093 controls). Associations were tested using Sequence Kernel Association Test-Optimal across variant classes (rare variants, nonsynonymous, loss-of-function, and predicted damaging variants with combined annotation-dependent depletion score >20), followed by meta-analysis across cohorts. Domain-level analyses were performed for variants located within protein domains. False discovery rate (FDR) correction was applied. Meta-analysis identified a significant association between rare variants in ST3GAL3 and Parkinson's disease (Pfdr\u2009=\u20090.04). Domain-based analyses showed enrichment of nonsynonymous variants within the \u03b2-acetyl-hexosaminidase-like domain of HEXA (P\u2009=\u20098.0\u2009\u00d7\u200910-4), although this signal did not survive correction (Pfdr\u2009= 0.154). In early-onset PD, domain-based analyses identified significant associations in NAGLU (Pfdr\u2009= 7.3\u2009\u00d7\u200910-6) and ST3GAL5 (Pfdr\u2009=\u20090.03). Rare variants across multiple lysosomal pathways, particularly those related to sialylation, ganglioside metabolism, ceramide biology, and lysosomal proteolysis, may contribute to PD susceptibility beyond GBA1, highlighting pathways for future replication and investigation. \u00a9 2026 The Author(s).

Aligned with the 3Rs (Reduction, Replacement, Refinement of animal experiments) and the EU's roadmap to phase out animal testing, zebrafish eleutheroembryos are key in developing New Approach Methodologies (NAMs) as they are non-protected until five days post-fertilization. While bisphenol A is restricted in the EU, the effects of bisphenol E (BPE) on thyroid hormone system (THS) sensitive endpoints and developmental neurotoxicity (DNT) remain unclear. We investigated whether BPE disrupts THS-sensitive endpoints and induces DNT in zebrafish eleutheroembryos. Based on adverse outcome pathways (AOPs): AOP 364 and AOP 157, we assessed eye morphology, inner plexiform layer (IPL), retinal pigmentary layer (RPE), posterior swim bladder inflation and swimming performance, and transcriptional analysis of THS- and DNT-related genes. We hypothesized that BPE would affect THS-sensitive endpoints, such as RPE and posterior swim bladder inflation, impairing swimming performance, and exert DNT effects through THS-mediated mechanisms. BPE impairs RPE without affecting overall eye development. However, transcriptional analysis of THS-related genes did not support a THS-mediated mechanism. BPE exposure also impaired posterior swim bladder inflation, which was identified as the primary contributor to impaired swimming performance. No effects were seen on quantitative brain measurements, leaving the sensitivity of zebrafish eleutheroembryos for brain morphological assessment unclear. Nevertheless, molecular DNT markers were detected, which could indirectly contribute to impaired swimming performance. Overall, our results demonstrate that the zebrafish eleutheroembryo is a valuable NAM model for assessing THS effects and DNT, and that BPE induces DNT and THS effects.\n\nID: 42262134\nTitle: Alpha-synuclein at the crossroads of host-virus interactions: immunological roles beyond the nervous system.\nAbstract: Alpha-synuclein (\u03b1-syn) is best known as a presynaptic protein that supports synaptic vesicle dynamics and neurotransmission. Conversely, misfolded or aggregated \u03b1-syn represents a hallmark of synucleinopathies, including Parkinson's disease. Beyond the nervous system, \u03b1-syn has been detected in peripheral compartments, including blood cells and selected epithelial tissues, although the robustness and context dependence of expression outside neuronal and erythroid lineages remain under active investigation. Also, it can be released extracellularly through unconventional secretion or cell damage. These observations have reframed \u03b1-syn as an immune-relevant molecule positioned at host-pathogen interfaces, endowed with antimicrobial peptide-like and damage-associated molecular pattern-like properties that enable shaping of both innate and adaptive immunity. Increasing evidence indicates that viral challenge alters \u03b1-syn expression, localization, and conformational states in central and peripheral settings, in part through interferon-dependent programs that couple antiviral immunity with cellular homeostasis. A plethora of RNA viruses, such as influenza virus, flavivirus, enterovirus, and coronavirus, perturb \u03b1-syn abundance, post-translational modifications, trafficking, secretion, and aggregation propensity. These effects converge on shared mechanisms that include altered proteostasis, autophagy-lysosomal dysfunction, oxidative and mitochondrial injury, and inflammatory signaling. Importantly, outcomes are highly context dependent, ranging from cell-intrinsic antiviral restriction to aggregation-prone states that may fuel chronic inflammation and neurodegeneration. Collectively, the evidence discussed herein supports a dual framework in which \u03b1-syn contributes to antiviral defense; yet, under conditions of sustained inflammation or impaired clearance, it may undergo pathological transformation that promotes neuronal damage. Defining when virus-induced \u03b1-syn responses are protective versus pathogenic, and clarifying their relevance to human disease, will be critical for developing strategies that target host-virus interactions, neuroinflammation, and \u03b1-syn proteostasis in infection-associated synucleinopathies.\n\nID: 42259955\nTitle: Aging in a highly polluted world: challenges and solutions to prevent Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder globally and a leading cause of disability and death among the elderly. As populations age worldwide, the epidemiological burden of AD is expected to more than double by 2050, surpassing 150\u00a0million affected individuals. While genetic susceptibility, particularly the apolipoprotein E \u03b54 (APOE4) allele, modulates individual risk, most AD cases are late-onset and shaped by complex interactions between genetic background and modifiable environmental exposures. Environmental pollution has emerged as a critical and potentially preventable contributor to this burden. The 2024 Lancet Commission on Dementia Prevention, Intervention, and Care has identified 14 modifiable risk factors, with air pollution explicitly included. Drawing on evidence from human epidemiological cohorts, experimental animal models, and in vitro neuronal/glial systems, the present review aims to synthesize mechanistic evidence linking environmental pollutant classes to AD-relevant neuropathology. The review examines the growing body of evidence linking major categories of environmental pollutants (ambient particulate matter, heavy metals, pesticides, PFAS, and emerging contaminants including microplastics and nanoplastics) to AD risk and pathogenesis. Special attention is given to studies showing that the characteristic neuropathological features of AD may emerge in children and young adults chronically exposed to heavily polluted urban environments, which highlights critical concerns about when and how these changes develop throughout life. Shared mechanistic pathways through which environmental pollutants promote neurodegeneration are discussed, including neuroinflammation, oxidative stress, blood-brain barrier disruption, tau kinase dysregulation, epigenetic reprogramming, and gut-brain axis dysbiosis. The review also examines the amplifying role of biological aging on neurotoxic vulnerability and proposes a comprehensive, multi-level prevention framework addressing individual exposure reduction, clinical risk identification, and population-level policy interventions.\n\nID: 42259119\nTitle: Polystyrene nanoplastics induce mitochondrial dysfunction and stress responses in human PBMCs.\nAbstract: Plastics continuously fragment into micro- and nanoplastics (MPs/NPs), which are increasingly recognized as emerging environmental contaminants of global concern. Human exposure to nanoplastics through air, food, and water is becoming unavoidable; however, their direct effects on human immune cells remain poorly understood. Due to their small size, NPs can enter the circulation and directly interact with immune cells, yet their cellular effects in humans remain poorly understood. In this study, we investigated the impact of polystyrene NPs on human peripheral blood mononuclear cells (PBMCs) using an integrated approach that combined imaging, mitochondrial stress testing, basophil activation assays, and single-cell RNA sequencing. Confocal microscopy confirmed efficient cytoplasmic internalization of 25-nm NPs. Optical diffraction tomography revealed that even short-term (1\u202fh) exposure induced pronounced biophysical remodeling, including reduced cell volume and dry mass alongside increased intracellular density and refractive index. Seahorse metabolic profiling demonstrated substantial suppression of mitochondrial respiration across major immune subsets, reflected in reduced basal and maximal respiration, ATP-linked oxygen consumption, and spare respiratory capacity. Basophil activation remained unaffected by NP exposure. Single-cell transcriptomics identified a distinct NP-induced \"stress-cell\" population, characterized by upregulation of heat-shock and proteostasis pathways and concomitant downregulation of mitochondrial-encoded transcripts. Together, these data show that NPs rapidly disrupt mitochondrial function and activate proteotoxic stress programs in human immune cells. By situating these mechanisms within the One Health framework (human, animal and the planet health), our findings highlight how environmental nanoplastic pollution may translate into immune dysregulation and inform integrated environmental-public health risk assessments.\n\nID: 42257982\nTitle: Comprehensive evaluation of Lactobacillus strains and Bacillus coagulans against Bisphenol-A induced neuronal and cardiac toxicities.\nAbstract: Bisphenol A (BPA) has emerged as an environmental pollutant in the last decade. It is imperative to reduce and limit the absorption of this chemical as it can negatively affect vital organs, including brain and heart. There is no direct curative option for BPA-induced toxicity hence, to bridge this gap, this study was conducted to evaluate the prophylactic effects of Bacillus coagulans against BPA-induced neuro- and cardio- toxicities. In silico techniques were utilized to study the toxicophore of BPA, followed by in vitro probiotic studies to select the best strain with the most physiological stability and pharmacokinetic properties. Positive effect of probiotic against cytotoxicity produced by BPA was studied on PC12 and H9c2 cell lines. After model standardization to select suitable dose for BPA induced toxicities, 42 male wistar rats were divided into seven groups for in vivo studies: normal control (Group 1), probiotic (Group 2), BPA alone (Group 3), BPA\u2009+\u2009standard treated (Group 4), BPA\u2009+\u2009probiotic (low dose) (Group 5), BPA\u2009+\u2009probiotic (medium dose) (Group 6), and BPA\u2009+\u2009probiotic (high dose) (Group 7). Morphological parameters, blood pressure, electrocardiogram, inflammatory cytokine level, antioxidant levels, brain and heart biomarkers, and histology were evaluated to investigate the protective effects. The probiotic showed protective effects, reflected by modulation of MDA, BDNF, CK-MB and IL-6 levels, along with improved tissue histology; however, a consistent dose-dependent response was not observed across all evaluated parameters. Thus, the findings suggest that Bacillus coagulans may have prophylactic potential against BPA-induced neuronal and cardiac toxicities.\n\nID: 42252285\nTitle: Lysine acetyltransferase 8-mediated histone acetylation, regulated by GBA1, is associated with lysosomal function related to \u03b1-Synuclein pathology.\nAbstract: Lysosomal defects are closely linked to Parkinson's disease (PD). Mutations in the GBA1 gene, encoding the lysosomal enzyme glucocerebrosidase (GCase), are major genetic risk factors for PD. GBA1 deficiency causes lysosomal dysfunction, leading to \u03b1-synuclein (\u03b1-syn) accumulation and PD progression. However, the underlying mechanisms remain unclear. In this study, we identified a novel GBA1-KAT8 regulatory pathway that controls lysosomal activity. GBA1 overexpression enhances lysosomal enzyme expression, regulates histone H4 acetylation at K16 via KAT8, and promotes lysosome-associated gene expression, highlighting an epigenetic mechanism in lysosomal biogenesis. Furthermore, GBA1 upregulated KAT8 expression, increased lysosomal enzyme levels, and decreased PFF-induced \u03b1-syn accumulation both in vitro and in vivo. The involvement of KAT8 as a critical acetyltransferase that modulates nuclear-lysosomal signaling pathways provides a mechanistic explanation for GBA1 deficiency-induced lysosomal dysfunction in association with PD pathology.\n\nID: 42248811\nTitle: Ginsenoside Rg1, a Natural Lysosomal Enhancer, Alleviates Parkinson's Disease Pathology via Cathepsin D-Dependent Regulation of \u03b1-Synuclein Homeostasis.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by dopaminergic neuron loss and \u03b1-synuclein (\u03b1-syn) aggregation, often linked to lysosomal dysfunction. Cathepsin D (CTSD), a lysosomal hydrolase essential for \u03b1-syn clearance, becomes functionally impaired when its maturation is disrupted, exacerbating proteostatic stress. This study investigated whether ginsenoside Rg1(Rg1) restores CTSD maturation and lysosomal function to mitigate PD pathology. MPTP-induced zebrafish and mouse PD models, as well as MPP+-treated SH-SY5Y cells, animals and cells were treated with Rg1 at different concentrations. Motor behavior, dopaminergic neuron survival, \u03b1-syn clearance, CTSD maturation, lysosomal activity, endoplasmic reticulum (ER) stress, oxidative stress, autophagic flux, and apoptosis were systematically evaluated. Rg1 improved locomotor performance and preserved dopaminergic neurons, promoted \u03b1-syn clearance, and enhanced CTSD maturation in lysosomes. These effects coincided with reduced ER and oxidative stress, normalized autophagic flux, and decreased apoptosis. Rg1 functions as a natural lysosomal enhancer, restoring lysosome-ER homeostasis and counteracting multiple pathogenic pathways in PD. The findings reveal a CTSD-dependent regulatory axis in \u03b1-syn homeostasis and highlight Rg1 as a promising multi-target therapeutic candidate for PD.\n\nID: 42234058\nTitle: Protective effects of zingerone against bisphenol-A induced oxidative stress and apoptosis in SH-SY5Y cells: the role of TRPM2 channel.\nAbstract: Bisphenol A (BPA) is a common environmental endocrine disruptor that causes oxidative stress and neuronal damage. However, the role of redox-sensitive ion channels, such as TRPM2, and potential protective interventions have not been thoroughly explored. This study provides novel mechanistic insight into TRPM2-mediated neuronal damage and highlights the potential of zingerone (ZG) as a natural therapeutic strategy against environmental neurotoxicity. The cells were exposed to BPA (250 \u00b5M) with or without ZG (25 \u00b5M) for 24\u00a0h. We assessed cell viability (CCK-8), oxidative stress parameters (MDA, ROS, GSH, and GSHPx), inflammatory cytokines (IL-1\u03b2, IL-6, and TNF-\u03b1), apoptotic caspases (3, 8, and 9), and TRPM2/PARP-1 expression using ELISA and Western blotting. Exposure to BPA significantly reduced cell viability and triggered oxidative imbalance, inflammation, and apoptosis, as well as upregulation of TRPM2. In contrast, co-treatment with ZG restored antioxidant defences, suppressed cytokine release, inhibited caspase activation, and downregulated PARP-1/TRPM2 signaling. These results suggest that ZG protects against BPA-induced neuronal damage by regulating PARP-1/TRPM2-associated redox signalling pathways and provide further evidence for TRPM2's involvement in environmental neurotoxicity.\n\nID: 42231093\nTitle: Nrf2/NOX2 Pathway Dysregulation and Oxidative Stress Biomarkers in Gaucher Disease-Associated Parkinsonism: Insights Into a Potential Therapeutic Target.\nAbstract: Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder, yet its underlying genetic and molecular mechanisms remain incompletely understood. Variants in the GBA gene, encoding the lysosomal enzyme glucocerebrosidase, are not only responsible for Gaucher disease (GD) but also represent a significant genetic risk factor for PD, contributing to lysosomal dysfunction, oxidative stress and autophagy impairment. Among the key regulators of redox homeostasis, the Nrf2/NOX2 signalling axis has emerged as a pivotal pathway in the modulation of neuroinflammation and neurodegeneration. This study aims to explore the pathogenic link between GBA mutations and PD, focusing on the redox imbalance and the role of Nrf2 signalling in an in\u00a0vivo Gba D409V knock-in (KI) mouse model, compared to wild-type (WT) C57BL/6J controls. Animals 8-weeks old were evaluated over a 3-month period, with tissue and behavioural assessments conducted at 7, 14, 30, 60 and 90\u2009days. Early timepoints (7 and 14\u2009days) did not reveal significant changes in behavioural performance, expression of PD-related markers (TH, DAT, \u03b1-synuclein), or oxidative stress indicators, including Nrf2, NOX2, malondialdehyde (MDA) and nitrate/nitrite levels. However, at 30, 60 and especially 90\u2009days, significant alterations emerged, particularly a disrupted Nrf2/NOX2 balance, accompanied by molecular and biochemical signatures of oxidative stress. These findings suggest a time-dependent progression of oxidative alterations in this GD model and support the role of GBA variants in promoting neurodegenerative processes. Unravelling these mechanisms is essential for the identification of early biomarkers and may offer new therapeutic insights for GBA1-associated PD.\n\nID: 42212217\nTitle: Trans sodium crocetinate protects against hepatotoxicity induced by bisphenol A in rats.\nAbstract: Bisphenol A (BPA) is a monomer used in producing a wide range of materials and products, and it is recognized as an endocrine disruptor. Exposure to BPA can cause toxicity in multiple organs, especially the liver. Trans sodium crocetinate (TSC) is a synthetic salt derived from crocetin extracted from Crocus sativus. TSC exhibits antioxidant, anti-apoptotic, and properties that inhibit autophagy. This study evaluates the effects of TSC on liver toxicity induced by BPA. A total of 42 rats were allocated into seven groups, including those exposed to BPA at a dose of 75 mg/kg, BPA and trans sodium crocetinate (TSC) at doses of 10, 20, and 40 mg/kg, and groups receiving olive oil, distilled water, or TSC (40 mg/kg) alone. The total antioxidant capacity (TAC), lipid peroxidation, and glutathione, as well as serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), and total bilirubin were assessed using colorimetric methods. Reactive oxygen species (ROS) and liver protein expression were quantified using fluorimetric and western blot techniques. TSC, at the dose of 40 mg/kg, reduced the levels of ROS and lipid peroxidation induced by BPA, while remarkably increasing the glutathione content and total antioxidant capacity (TAC) in liver tissue. Moreover, TSC markedly alleviated the BPA-induced increases in caspase-3 protein levels and in the activities of ALT, AST, ALP, and LDH, as well as in serum bilirubin T. Altogether, TSC can be regarded as a supplement to protect against BPA-induced hepatotoxicity due to its potent antioxidant and anti-apoptotic effects.\n\nID: 42210609\nTitle: The TRPM2-PARP-1 Axis Involvement in Bisphenol A and Nonylphenol-Induced Ferroptosis in Trigeminal Ganglion Cells.\nAbstract: Environmental contaminants like bisphenol A (BPA) and nonylphenol (NP) are recognized neurotoxicants; however, the molecular mechanisms underlying their impact on sensory ganglia, specifically the trigeminal ganglion (TG), remain critically underexplored. This study explored the potential of BPA and NP to drive neuronal injury and ferroptosis linked to oxidative stress, acting through the transient receptor potential melastatin 2 (TRPM2)-poly (ADP-ribose) polymerase-1 (PARP1) signaling axis. Forty-two adult male Wistar rats were allocated into seven groups (control, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] NP, and low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA\u2009+\u2009NP) and treated orally for 21\u2009days. We employed a combinatorial approach of biochemical assays and immunohistochemistry to evaluate oxidative stress markers, ferroptosis hallmarks (glutathione peroxidase 4 [GPX4], solute carrier family 7 member 11 [SLC7A11], and transferrin receptor [TfRC]), apoptotic mediators (Caspase-3 and Caspase-9), and inflammatory cytokines, as well as the expression of TRPM2 and PARP-1. Results demonstrated that BPA and NP exposure triggered a robust, dose-dependent accumulation of reactive oxygen species (ROS) and lipid peroxidation, concomitant with downregulation of anti-ferroptotic proteins (GPX4 and SLC7A11) and upregulation of TfRC. This toxic insult simultaneously activated apoptotic and inflammatory cascades. Crucially, TRPM2 and PARP-1 were significantly upregulated, implying a potential role for the TRPM2-PARP-1 axis as an upstream modulator of oxidative stress-induced ferroptosis and neuroinflammation. Collectively, these findings provide novel mechanistic insights into phenol-induced neurotoxicity, highlighting the inhibition of the TRPM2-PARP-1 axis as a promising therapeutic strategy to mitigate environmental neurodegeneration in sensory neurons.\n\nID: 42190388\nTitle: Parental Bisphenol S exposure induces oxidative stress and disrupts serotonergic and cholinergic neurotransmission in zebrafish offspring.\nAbstract: Bisphenol S (BPS), a structural analogue of bisphenol A (BPA), is widely used in consumer products and increasingly detected in aquatic environments, raising concerns about its long-term ecological and health impacts. Although short-term developmental neurotoxicity of BPS has been documented, its potential intergenerational effects remain largely unknown. In this study, zebrafish (F0) embryos were exposed to an environmentally relevant concentration of BPS (30\u202f\u00b5g/L) from 4 to 120\u202fh post-fertilization (hpf) and subsequently reared in clean water until adulthood (6 months). Adult fish were then crossed to generate F1 offspring through maternal, paternal, and parental lineages, which were assessed for behavioural and molecular endpoints. Although hatching success, survival, and behaviour remained unaffected across maternal, paternal, and parental lineages, distinct lineage-specific molecular alterations were observed. All lineages exhibited increased reactive oxygen species, lipid peroxidation, and neuronal apoptosis, accompanied by suppression of gpx1a and mn-sod and induction of creb1a, indicating persistent oxidative stress and apoptotic activation. The serotonergic pathway showed marked vulnerability, with downregulation of htr1aa, htr2a, and slc6a4a and elevated serotonin levels, particularly in the parental lineage. Cholinergic signalling was similarly affected, as chata and slc18a3a were upregulated while acetylcholine concentrations increased, suggesting cholinergic hyperactivity. Neurotrophic markers revealed bdnf upregulation and manf downregulation, implying impaired neuronal maintenance and endoplasmic-reticulum stress. Lineage comparisons revealed that the maternal BPS lineage primarily exhibited alterations in serotonergic and cholinergic signalling, whereas the paternal BPS lineage showed stronger oxidative and neurotrophic disruption, and the parental BPS lineage exhibited both, representing the most comprehensive molecular perturbation. These results demonstrate that parental exposure to environmentally relevant BPS concentration induces stable, lineage-specific transcriptional and neurochemical reprogramming without overt phenotypic change. Such latent molecular neurotoxicity highlights the capacity of BPS to silently compromise neurotransmission and stress-response networks across generations, emphasizing the need to include molecular inheritance endpoints in future BPS risk assessments.\n\nID: 42185558\nTitle: Protective effects of gastrodin against bisphenol A-induced dopaminergic dysregulation and cognitive impairment in rats.\nAbstract: Gastrodin (GAS) is a potent neuroprotective compound extracted from the traditional Chinese medicinal herb Gastrodia elata Blume. However, its role in mitigating bisphenol A (BPA)-induced dopaminergic dysfunction and cognitive impairment remains insufficiently explored. Many studies have shown that BPA exposure causes neurodegeneration via mechanisms involving dopaminergic system dysfunction, oxidative stress, and neuroinflammation. Therefore, the present study aimed to investigate whether GAS mitigates the effects of BPA-induced cognitive impairment through neuroinflammation in a rat model. Weanling male\u00a0Wistar rats exposed to BPA (50\u00a0\u00b5g/kg b.wt.\u2009\u00d7\u200930\u00a0days, po) were subsequently treated with GAS at two dose levels (30 and 60\u00a0mg/kg b.wt., ip\u2009\u00d7\u20097\u00a0days). After 24\u00a0h, neurobehavioral functions (Barnes maze and Y-maze tests), cresyl violet staining, and ultrastructural analysis were performed, demonstrating significant memory deficits and neuronal degeneration in BPA-exposed rats. In contrast, GAS treatment significantly improved memory impairment and reduced neuronal cell death in the prefrontal cortex (PFC). mRNA, protein, and immunohistochemical expression of inflammatory markers such as tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), (Iba-1), glial fibrillary acidic protein (GFAP), and nuclear factor kappa B-p65 (NF\u03baB-p65) were significantly increased in BPA-treated rats, indicating enhanced glial activation and neuroinflammation, whereas GAS effectively attenuated these alterations. Additionally, dopaminergic markers such as\u00a0tyrosine hydroxylase (TH), dopamine transporter-1/solute carrier family 6 member 3 (DAT-1/SLC6A3), and dopamine receptor D4 (DRD4) were significantly downregulated following BPA exposure and were restored by GAS treatment. Overall, findings suggested that\u00a0GAS exerts protection against BPA-induced neurotoxicity by suppressing NF-\u03baB-mediated neuroinflammatory response and modulating dopaminergic signaling, thereby improving cognitive and neuronal outcomes in the PFC.\n\nID: 42166000\nTitle: Chronic bisphenol A exposure activates the cGAS-STING-NLRP3 axis driving persistent hippocampal neuroinflammation and cognitive impairment.\nAbstract: Bisphenol A (BPA), a main component of polycarbonate plastics and epoxy resins, has been reported to cause chronic neuroinflammation and cognitive impairment in animal models. However, the precise molecular mechanisms of BPA-induced chronic neuroinflammation remain unknown. In this study, male C57BL/6 mice were administered BPA at different doses for one month, followed by a one-month washout period. We then conducted behavioral tests, oxidative stress assays, and immunohistochemistry to quantify neuronal density and the activation of microglia and astrocytes in the central nervous system. We also carried out RT-qPCR gene expression analysis of the hippocampus for the cGAS-STING-NLRP3 pathway, cytokine assays, and microglial markers to decipher the immune responses in the hippocampus following BPA exposure. BPA induced dose-dependent behavioral deficits, which were most pronounced at 50\u00a0mg/kg. These findings suggest that cGAS-STING signaling acts as a key upstream mediator of BPA-induced hippocampal neuroinflammation and cognitive dysfunction.\n\nID: 42155171\nTitle: Targeting lysosomal dysfunction with small-molecule TRPML1 ligands: Therapeutic opportunities in lysosomal storage disorders, neurodegeneration and beyond.\nAbstract: TRPML1, a lysosomal Ca2+ channel, has emerged as a clinically relevant target due to its genetic and mechanistic links to lysosomal storage disorders and neurodegenerative diseases, including Gaucher disease, Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis. This evidence has prompted TRPML1 drug discovery efforts across academia and industry, with several small-molecule agonists advancing toward clinical development. In this review, we provide a comprehensive overview of the therapeutic potential of TRPML1 as a molecular target from a medicinal chemistry perspective. We summarize the structural basis of channel activation and inhibition, highlighting insights from recent cryo-EM studies that define the principal ligand-binding sites and mechanisms of allosteric modulation. We systematically survey the chemical space of TRPML1 ligands reported to date, including diverse agonist and antagonist chemotypes, and extend this analysis to encompass undisclosed or recently disclosed compounds emerging from industry pipelines. Furthermore, we discuss key determinants of ligand design and developability, including the challenges associated with targeting a deeply embedded, lipophilic binding pocket within the membrane. Overall, the available evidence positions TRPML1 as a promising target for small-molecule drug discovery and provides a framework for the rational design of next-generation lysosome-directed therapeutics.\n\nID: 42152630\nTitle: Role of Lysosomal Genes for Parkinson's Pathogenesis: Insights from Molecular Mechanism to Therapeutic Strategies.\nAbstract: Current review aims to clarify the role of lysosomal genes in the pathogenesis of Parkinson's Disease (PD), directing on the molecular mechanisms underlying lysosomal dysfunction and its involvement to \u03b1-synuclein accumulation. To deliberates PD-related genes including GBA1, LRRK2, VPS35, PRKN, PINK1, TMEM175, ATP13A2, ATP10B, and DJ1, highlighting their contribution in lysosomal damage. It investigates the disorder of lysosomal enzymes such as cathepsins, glucocerebrosidase, galactocerebrosidase, and acid sphingomyelinase, and the consequent impairment of the autophagic-lysosomal pathway, which helps pathological \u03b1-synuclein accumulation. Therapeutic approaches targeting lysosomal dysfunction and \u03b1-synuclein pathology are reviewed, including pharmacological chaperones, immunization strategies, enzyme replacement therapies, and small-molecule oligomer modulators. While recent clinical trials expose certain limitations, combinatorial treatment strategies show potential to improve therapeutic efficacy. Lysosomal pathways are critical contributors to PD pathogenesis and denote promising targets for intervention. Integrating mechanistic understandings with developing therapies underlines the importance of targeting lysosomal dysfunction to mitigate \u03b1-synuclein aggregation and advance PD treatment.\n\nID: 42140406\nTitle: Polystyrene microplastic exposure induces hepatic damage via immune-modulated autophagy and ferroptosis in Nile tilapia (Oreochromis niloticus).\nAbstract: Hepatic damage in fish induced by microplastic exposure has garnered increasing concern, yet its molecular mechanisms remain insufficiently elucidated. In this study, 30\u00a0days after hatching (dah) Nile tilapia were subjected to sub-chronic exposure to polystyrene microplastics (PS; 100\u00a0nm) for 14\u00a0days. Histopathological examination revealed evident inflammatory cell infiltration in the livers of PS-exposed fish compared to the control fish. Transmission electron microscopy showed elevated mitochondrial rupture and increased autophagosome formation. Immunofluorescence and Western blot analyses showed upregulated Lc3b and downregulated P62 protein levels, suggesting enhanced hepatic autophagy. Transcriptomic profiling of liver tissues and subsequent KEGG enrichment analysis highlighted significant upregulation of genes involved in the MAPK, NOD-like receptor, Toll-like receptor, and autophagy signaling pathways. Metabolomic profiling indicated notable enrichment in glutathione metabolism, ferroptosis, cysteine and methionine metabolism, and the NOD-like receptor pathway. Integrated transcriptomic and metabolomic KEGG analysis consistently identified ferroptosis as a centrally enriched pathway. Further gene expression and metabolite analyses demonstrated marked upregulation of immune-related genes, autophagy-related genes, and ferroptosis-pathway genes. Concurrently, ferroptosis-related metabolites including glutathione and cysteine were significantly decreased. Meanwhile, levels of lipid metabolites such as 2-oleoylglycerol were also reduced, whereas lipid peroxidation products represented by 4-hydroxynonenal were significantly increased. Additional validation confirmed increased expression of inflammatory factors (il-1\u03b2, tgf-\u03b2, nlrp3) and altered iron homeostasis in the PS-exposed fish liver. These findings indicate that sub-chronic PS exposure promotes hepatic ferroptosis via immune-mediated activation of autophagy, ultimately leading to liver injury in Nile tilapia. Our study provides novel insights into the mechanisms underlying microplastic-induced tissue damage in aquatic organisms.\n\nID: 42134007\nTitle: Curcumin alleviates BPAF-induced ferroptosis in caprine endometrial epithelial cells through inhibition of endoplasmic reticulum stress and autophagy.\nAbstract: Bisphenol AF (BPAF) is widely used as a substitute for bisphenol A (BPA) in the plastics industry. However, it is known to cause reproductive toxicity in both humans and animal models. Curcumin, a polyphenolic compound from turmeric, is known for its potent anti-inflammatory and antioxidant effects. We previously showed that curcumin alleviates BPAF-induced apoptosis in caprine endometrial epithelial cells (EECs). However, the underlying mechanisms of BPAF toxicity remain unclear. The aim of this study was to investigate whether ferroptosis contributes to BPAF-induced injury in EECs and to assess the protective role of curcumin. We demonstrate that BPAF triggers ferroptosis in EECs: ferroptosis-related factors (COX2, FACL4, and NCOA4) were upregulated, and GSH content was increased. These effects were significantly reversed by the ferroptosis inhibitor Fer-1, which restored cell viability and reduced MDA accumulation. Mechanistically, BPAF-induced ferroptosis was autophagy-dependent, as evidenced by upregulated ATG5, Beclin1, and LC3, and enhanced autophagic flux. Inhibition of autophagy by CQ significantly attenuated ferroptosis and improved cell viability. Furthermore, ER stress acted as an upstream regulator, as its inhibitor 4-PBA alleviated both autophagy and ferroptosis. BPAF also disrupted cellular iron homeostasis by promoting NCOA4-mediated ferritinophagy, resulting in intracellular iron accumulation. Curcumin pretreatment alleviated BPAF-induced ferroptosis by suppressing ferritinophagy and restoring iron homeostasis. Moreover, activation of the PI3K/AKT/mTOR and Nrf2/HO-1 pathways may exert protective effects by suppressing autophagy and lipid peroxidation. In conclusion, this study indicates that ferroptosis is a key mechanism underlying BPAF-induced cytotoxicity in EECs. Curcumin protects against this damage by inhibiting ER stress and autophagy, providing a potential therapeutic strategy for BPAF-related uterine diseases.\n\nID: 42115479\nTitle: Small heat shock proteins with two alpha-crystallin domains: a new set of proteins in the earthworm Eisenia fetida with differential transcriptional responses to stressors.\nAbstract: Climate change and environmental pollution are two primary challenges facing biodiversity and ecosystem stability. Earthworms are key contributors to soil structure and nutrient cycling, and their molecular stress responses can provide an early indication of soil health impairment. Heat shock proteins are central to the stress response, and small heat shock proteins (sHSPs) are ATP-independent chaperones that limit stress-induced protein aggregation. Because their expression is stress-sensitive, sHSPs are promising molecular markers for soil stress and contributors to thermotolerance. Eisenia fetida, a widely used ecotoxicology model, relies on molecular chaperones like small heat shock proteins (sHSPs) for stress tolerance. We previously characterized sHSPs containing a single \u03b1-crystallin domain (ACD) in E. fetida. Here, we report the first identification of sHSPs containing two \u03b1-crystallin domains (ACDs) in annelid species. These genes were identified from an E. fetida transcriptome, their domain architecture was defined, and their transcriptional responses were quantified under heat stress, desiccation, and exposure to two pollutants (bisphenol A and endosulfan), including combined exposure with elevated temperature. Double-ACD sHSPs showed stimulus- and time-dependent transcriptional patterns. Moderate heat and desiccation primarily induced late (24\u00a0h) upregulation of several sHSP genes, whereas bisphenol A at optimal temperature did not result in significant transcriptional change and endosulfan produced only limited changes under single-stressor exposure. In contrast, combined exposure to endosulfan and elevated temperature triggered a significant upregulation of multiple sHSP genes, consistent with an additive stress effect. These results expand this protein family diversity in annelids and support a staged sHSP response in which structurally distinct sHSPs may contribute to resilience under prolonged or combined environmental stress.\n\nID: 42114425\nTitle: Life-cycle exposure to tris(2-butoxyethyl) phosphate at environmentally relevant concentrations induces progressive Parkinsonian-like neurodegeneration via lysosomal dysfunction in Caenorhabditis elegans.\nAbstract: Environmental contaminants are increasingly recognized as key risk factors for chronic diseases, including neurodegenerative disorders. Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology. Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters.\n\nID: 42407165\nTitle: Ocean warming shapes the marine plastisphere: Microbial assembly, vector effects, and biogeochemical feedbacks of microplastics.\nAbstract: Marine microplastic pollution has evolved into a global ecological crisis, shifting from physical contamination to microbial habitats on plastic surfaces. The colonization of microorganisms on synthetic surfaces is not random but is driven by physicochemical and biological factors. This narrative review summarizes the properties of microplastics that influence the composition and assembly of microbial communities. We emphasize that polymer types (e.g., polyethylene and biodegradable polylactic acid) act as primary templates, whereas surface interface properties, including hydrophobicity and adsorption of natural organic matter and biomolecules, determine attachment kinetics. We address the size-dependent effects of microplastics, focusing on how nanoscale particles cause greater oxidative stress than micron-scale particles. Beyond community structuring, microplastics serve as vectors facilitating the long-distance migration of marine pathogens and the horizontal transfer of antibiotic resistance genes, thereby expanding the geographical range of ecological risks. Significantly, bidirectional interactions within the plastisphere (the microbial community and associated biofilm that develop on plastic surfaces) reshape marine biogeochemical cycles. By altering the buoyancy and sinking rates of organic aggregates in the water column, microplastic-microbe aggregates perturb the biological carbon pump and modulate nitrogen transformation processes. This review provides an updated framework that integrates ocean warming into predictive ecological models for plastisphere assembly and function, addressing a gap in climate-microplastic research. Using mechanistic insights from 2010 to 2025, we identify critical knowledge gaps and advocate for advanced multi-omics and stable isotope probing to characterize the functional metabolic pathways of the plastisphere in a changing ocean.\n\nID: 42407160\nTitle: Detection and cross-organ characterization of physiological response to microplastic stress in Panax ginseng based on hyperspectral imaging assisted with machine learning.\nAbstract: Microplastic pollution can affect growth and quality of medicinal plants, yet rapid detection of microplastic stress responses remains underexplored. We treated ginseng with polyethylene microplastics, acquired leaf hyperspectral images (HSI) on day 23, and constructed machine learning models for identifying stress levels and predicting physiological indicators. Furthermore, the applicability of successive projections algorithm (SPA) and competitive adaptive reweighted sampling (CARS) for characteristic wavelength selection was compared. Results showed that polyethylene stress significantly affected the physiological state. The classification models effectively identified microplastic stresses of different concentrations, with the support vector machine (SVM) model performing the best (accuracy of 85.2%). For quantitative prediction, the partial least squares regression (PLSR) model exhibited optimal performance for indicators including chlorophyll (Chl) (RPD\u202f=\u202f3.98), soluble sugar (RPD\u202f=\u202f2.56) and peroxidase (POD) (RPD\u202f=\u202f2.89), and the convolutional neural network performed better in superoxide dismutase (SOD) prediction (aerial RPD\u202f=\u202f3.27, underground RPD\u202f=\u202f2.65). Leaf spectral data enabled prediction of aerial and underground physiological indicators (RPD\u202f=\u202f2.10 to 2.73), indicating that aerial spectral information reflected underground physiological state. Characteristic wavelength selection results showed that SPA had advantages for SOD prediction, while CARS performed better for the remaining seven indicators (RPD >2.0). In conclusion, HSI combined with machine learning models enabled rapid nondestructive identification of microplastic stress responses and prediction of key physiological indicators in ginseng, suggesting quantifiable relationships between aerial spectral data and underground physiological states. This study provides a technical prototype for the growth detection of medicinal plants.\n\nID: 42406551\nTitle: Bifidobacterium Pseudolongum-Derived Inosine Mitigates Polystyrene Nanoplastics-Induced Hepatic Injury by Inhibiting the Polarization of M1 Macrophages.\nAbstract: Nanoplastics (NPs) exposure can cause severe hepatic injuries. Gut microbiota is considered a contributing factor to multiple hepatic injuries. However, its role in NPs-induced hepatic injuries remains unclear, and microbial intervention strategies are required. Our results reveal that oral exposure to polystyrene NPs reduces gut probiotic Bifidobacterium pseudolongum (B.p) and its metabolite inosine. Gut microbiota from NPs-administered mice partially reproduces NPs-related impairment of gut homeostasis and hepatic injury in recipient mice. Moreover, B.p colonization improves NPs-induced gut homeostasis impairment and hepatic injury, and its protective effects are reproduced by supplementation with inosine. Mechanically, B.p colonization increases hepatic level of inosine and subsequently normalizes the expression of its target A2AR. Meanwhile, increased inosine inhibits the miR155/SOCS1/NF-\u03baB pathway and represses NPs-induced M1 macrophage polarization. CGS21680, an agonist of A2AR, effectively represses lipopolysaccharide (LPS)-induced M1 macrophage polarization and inhibits the miR155/SOCS1/NF-\u03baB pathway in vitro. Further, miR155 knockout inhibits NPs-induced M1 macrophage polarization, but does not influence the suppression of NPs on A2AR. These findings suggest that B.p-derived inosine can repress NPs-induced M1 macrophages polarization by inhibiting the miR155/SOCS1/NF-\u03baB pathway via targeting A2AR. Altogether, this study further clarifies the role of gut microbiota in NPs-induced hepatic injury and provides a potential microbial therapeutic strategy.\n\nID: 42406320\nTitle: Microplastic contamination in freshwater fish and human health implications: a global and Indian perspective.\nAbstract: Microplastic (MP) pollution has emerged as a pervasive threat to freshwater ecosystems worldwide, with increasing evidence of contamination in freshwater fish that serve critical ecological, economic, and nutritional roles. This review synthesizes current knowledge on the sources, pathways, detection methodologies, occurrence, tissue distribution, ecotoxicological effects, and human health implications of microplastics in freshwater fish. Major sources of MPs include urban wastewater, industrial effluents, agricultural runoff, aquaculture activities, and atmospheric deposition, which facilitate their entry into rivers, lakes, reservoirs, and wetlands. Advances in analytical techniques such as Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and pyrolysis-gas chromatography/mass spectrometry have improved MP detection; however, methodological inconsistencies continue to hinder data comparability. Globally, freshwater fish frequently ingest MPs, with fibers and fragments being the dominant morphotypes and polyethylene, polypropylene, polyethylene terephthalate, and polyamide the most common polymers. Beyond the gastrointestinal tract, MPs have been detected in gills, liver, muscle, gonads, and eggs, indicating potential translocation and reproductive transfer. Exposure to MPs can induce oxidative stress, tissue damage, metabolic disturbances, and reproductive impairment in fish. Furthermore, consumption of contaminated fish may expose humans to MPs and associated pollutants, raising concerns regarding food safety and public health. The review identifies key research gaps and highlights the need for standardized methodologies, long-term monitoring, risk assessment frameworks, and integrated mitigation strategies to protect freshwater biodiversity, fisheries, and food security.\n\nID: 42406299\nTitle: Microplastic-Induced Disruption of Intestinal Barrier Integrity and Triggering Neuroinflammatory Responses Through Gut-Brain Axis Dysregulation Mediated by NF-\u03baB/PPAR-\u03b3/BDNF Signalling Pathways.\nAbstract: Microplastics (MPs) are emerging environmental contaminants increasingly implicated in intestinal dysfunction and neuroinflammatory alterations through gut-brain axis (GBA) dysregulation. However, the mechanistic involvement of polyethylene (PE) and polypropylene (PP) MPs in GBA-associated neurotoxicity remains insufficiently understood. Therefore, the present study aimed to evaluate the impact of PE- and PP-MPs on intestinal barrier integrity, oxidative stress, neuroinflammation, and synaptic dysfunction. Following physicochemical characterization, experimental animals were orally exposed to PE- and PP-MPs (10 and 100\u00a0mg/kg BW) for 45 consecutive days. MP exposure significantly disrupted intestinal barrier integrity, reduced zonula occludens-1 expression, and altered short-chain fatty acid profiles, indicating impaired gut microbial metabolic activity. Concurrently, oxidative stress and inflammatory responses were evidenced by reduced antioxidant defence, increased lipid peroxidation, elevated inflammatory mediators, and altered neurochemical markers in small intestine and brain tissues. Behavioral abnormalities, increased amyloid precursor protein (APP) expression, tau-associated pathological alterations, and histopathological changes further indicated GBA impairment following MP exposure. Notably, PE-MPs produced comparatively greater toxicological effects than PP-MPs, particularly at higher dose. Overall, the findings demonstrate that chronic exposure to environmentally relevant PE- and PP-MPs disrupts intestinal homeostasis and promotes neuroinflammatory toxicity through GBA dysregulation.\n\nID: 42406194\nTitle: Nano-Confined Solar-Thermal Water Purification Boosted by Physical Field Disturbance Coupled with Ultrafast Non-Radical Advanced Oxidation Process.\nAbstract: Solar interfacial evaporation has undergone rapid development in recent years, yet its overall performance has reached a plateau due to limited advances in solar-thermal materials. Herein, we propose a synergistic nano-confinement and physical-field-modulation strategy that enables concurrent acceleration of solar-driven evaporation of water and on-site remediation of organic pollutants. Implemented in hollow mesoporous carbon nanocages integrated with Fe-N4 catalytic sites and inner wall plasmonic Au nanoparticles, the system couples mesoporous confinement with localized thermal and pressure perturbations to transform bulk water into thermodynamically activated intermediate states and substantially reduce the effective vaporization enthalpy. This integrated framework delivers high evaporation rates of 2.56\u00a0kg\u00a0m-2\u00a0h-1 in planar devices and 6.84\u00a0kg\u00a0m-2\u00a0h-1 in 3D architectures under one-sun irradiation, with a\u00a0kinetic enhanced Hertz-Knudsen-Schrage-derived evaporation coefficient. Simultaneously, the Fe-N4 sites enable non-radical peroxymonosulfate activation for ultrafast degradation of bisphenol A, achieving a rate of 182.5\u00a0L\u00a0g-1\u00a0min-1. This work establishes an ingenious strategy for coupling water-state regulation and catalytic pollutant degradation to break the performance bottleneck of solar-thermal purification.\n\nID: 42405146\nTitle: Detoxification of emerging contaminants bisphenol A (BPA) and malathion (MLT) through a visible-light-activated defect-engineered g-C3N4/MnO2 heterostructure.\nAbstract: Bisphenol A (BPA) and Malathion (MLT) are persistent organic pollutants widely detected in aquatic environments, posing significant ecological and human health risks. In this study, a visible-light-responsive photocatalyst based on MnO2 coupled with defective graphitic carbon nitride (MnO2/def-g-C3N4) was rationally designed for photocatalytic decomposition of 50 mg L-1 of BPA and 40 mg L-1 of MLT in water. Structural characterizations viz. XRD, XPS, Mott-Schottky analysis, UV-visible, AFM, SEM and TG-DTA etc. confirmed the successful formation of the p-n heterojunction with abundant surface defects, enhanced light absorption, and improved charge-carrier separation. The optimized MnO2/def-g-C3N4 (DCN-MnO2) composite exhibited conspicuously suppressed charge recombination and increased photoactivity under visible-light irradiation that showed rapid photodegradation efficiencies of BPA and MLT. The photocatalyst also demonstrated good stability and recyclability over four cycles with minimal activity loss. Mechanistic investigations suggested that the synergistic interaction between MnO2 and defective g-C3N4, along with defect-mediated charge transfer pathways, played a crucial role in enhancing photocatalytic performance. This work highlights MnO2/def-g-C3N4 as an efficient and sustainable visible-light photocatalyst for the decomposition of emerging organic contaminants in wastewater, offering promising potential for environmental remediation applications.\n\nID: 42405009\nTitle: Explainable deep learning in bloodstain pattern analysis: A pilot study using convolutional neural networks with saliency maps.\nAbstract: The purpose of this pilot study was to explore the feasibility of applying a novel explainable deep learning (XDL) methodology to classify Bloodstain Pattern Analysis (BPA) patterns. A convolutional neural network (CNN) was applied to classify impact and non-impact BPA patterns. A combination of BPA patterns generated by the researcher were supplemented by open-source BPA datasets and used for the CNN training. This methodology yielded promising results of up to 79% accuracy over 10 folds, validating the feasibility of such research avenues in the field. Furthermore, saliency maps were applied as the CNN's explainability layer, which is a novel application of XDL in BPA interpretations. The study highlights the potential of a novel BPA research stream in XAI while also underscoring the potential of the model to act as a possible reliable alternative tool for BPA experts over manual classification methodologies. This approach does not aim to replace the human element from the forensic science process but rather provide a tool to BPA experts to aid and expedite BPA interpretations without compromising on explainability metrics. It has the potential to increase transparency and trust in deep learning systems, which in turn would increase the reliability of forensic outcomes.\n\nID: 42404867\nTitle: Retreaded tires are an overlooked source of microplastics with distinct additive leaching and ecotoxicity.\nAbstract: Retreaded tires constitute a substantial segment of the commercial tire market and are an important source of tire wear particles (TWPs), yet the environmental risks of this major microplastic category remain uninvestigated. Here, we show that although the total additive mass is generally lower in TWPs from retreaded tires, these particles exhibit a markedly greater additive leaching potential, particularly for p-phenylenediamines (PPDs). Notably, the highly water-soluble additive N-isopropyl-N'-phenyl-p-phenylenediamine (IPPD), present at high concentrations in some retreaded-tire TWPs, is especially leachable. Correspondingly, leachates from retreaded-tire TWPs cause greater growth inhibition in Vibrio fischeri and Chlorella vulgaris than those from new or used tires. Furthermore, our numerical model projections under the Shared Socioeconomic Pathway 2 (SSP2) scenario show that global emissions of retreaded-tire TWPs could increase several hundred-fold by 2060. The substantial and growing risks identified in our study underscore the urgent need for broader investigations into the environmental impacts of these particles.\n\nID: 42404493\nTitle: Cross-study analysis identifies estrogen depletion and exposure duration as key determinants of bisphenol A transcriptomic potency in MCF-7 cells.\nAbstract: High-throughput transcriptomics (HTTr) is increasingly used to derive transcriptomic points of departure (tPODs) for chemical screening and prioritization, yet the robustness of these estimates across studies with differing experimental designs remains unclear. Here, we compared tPODs for bisphenol A (BPA) across multiple HTTr studies conducted in MCF-7 breast cancer cells, including datasets from our laboratory and others. Although these studies employed broadly similar approaches, they differed in key methodological features, including estrogen-depletion protocols, exposure duration, and maximum test concentration. Using a standardized downstream bioinformatic workflow, we evaluated the consistency of BPA transcriptomic potency estimates and assessed factors contributing to variability across studies. Overall, five of seven studies yielded BPA potency estimates within a similar concentration range, supporting the utility of HTTr for comparative potency assessment despite some inter-study variability. Notably, studies conducted under estrogen-depleted conditions yielded higher potency estimates relative to those performed under standard culture conditions. Similarly, longer exposure durations were associated with higher potency estimates. These findings indicate that, while tPODs are generally reproducible across HTTr studies, experimental conditions, particularly estrogen depletion and exposure duration, can influence potency estimates in MCF-7 cells. However, these factors were not systematically varied or independently controlled across datasets, and therefore their individual contributions cannot be definitively disentangled in the present analysis. This work highlights the importance of standardizing hormone conditions and exposure durations when applying HTTr to screen estrogenic chemicals. Collectively, these results support the use of HTTr for chemical prioritization while underscoring the need for harmonized experimental design in endocrine-relevant in vitro models.\n\nID: 42404354\nTitle: Small-Molecule Boron-10-Enriched Carriers with Exceptional Aqueous Solubility for Enhanced Boron Neutron Capture Therapy of Malignant Tumors.\nAbstract: Boron neutron capture therapy (BNCT) enables localized tumor ablation while minimizing damage to surrounding tissues, offering advantages for treating anatomically challenging sites. However, current boron carriers, such as sodium borocaptate (10BSH), suffer from inadequate tumor specificity. Herein, the present study details the design, synthesis, and preclinical evaluation of a novel small-molecule boron-10-enriched carrier, which was synthesized by covalent bond coupling 4-carboxy-3-fluorophenylboronic acid (FPBA) to 10BSH (FPBA-BSH), achieving a boron content of approximately 25 wt.%. FPBA-BSH efficiently penetrated the blood-brain barrier and demonstrated pronounced accumulation in orthotopic gliomas, achieving a boron concentration of 75.4 \u03bcg-B/g-tumor tissue, which was 4.2- and 3.7-fold higher than those with boronophenylalanine (BPA) and BSH, respectively. Moreover, FPBA-BSH exhibited markedly improved tumor selectivity, with tumor-to-normal tissue (T/N) and tumor-to-blood ratios of 52.0 and 7.2, respectively. The T/N ratio was approximately 19.3- and 14.1-fold greater than those observed for BPA and BSH. In the melanoma model, FPBA-BSH achieved an intratumor boron concentration of 114.4 \u03bcg-B/g-tumor tissue, representing 8.4- and 9.9-fold increases compared with BPA and BSH, respectively. Correspondingly, the T/N and tumor-to-blood ratios reached 135.1 and 8.6, indicating substantially enhanced tumor targeting and retention. The T/N ratio achieved with FPBA-BSH was approximately 26.0- and 34.6-fold higher than those obtained with BPA and BSH, respectively. Consistent with its superior tumor selectivity, FPBA-BSH-mediated BNCT induced pronounced tumor-selective cytotoxicity and markedly inhibited tumor growth in both orthotopic glioma and melanoma models compared with BPA, BSH, and untreated controls. These findings demonstrate that FPBA-BSH represents a promising small-molecule boron delivery agent with substantial potential for clinical BNCT applications.\n\nID: 42402953\nTitle: Uniform Lignin-Epoxy Hybrid Colloidal Spheres With Unprecedented pH 14 Alkaline Resistance: Facile Synthesis for Sustainable Photonic Materials.\nAbstract: Lignin, the most abundant aromatic biopolymer in nature, holds great promise for carbon-neutral materials development yet is limited by its inherent dark color and poor solvent stability. Transforming it into uniform lignin colloidal spheres (LCSs) with ordered arrays enables specific visible light reflection and thus presents tunable colors. However, industrial lignin-derived LCSs via self-assembly typically exhibit broad size distribution and poor solvent resistance. To address these challenges, we proposed a novel strategy combining solvent fractionation and surface covalent polymerization. Acetone/water fractionation effectively reduced lignin heterogeneity, narrowing LCSs size distribution. Bisphenol A diglycidyl ether (BADGE) was used as cross-linker to covalently polymerize hydroxyl groups, inhibiting LCSs dissolution. Two hybrid LCSs were fabricated: hy-LCSs via co-self-assembly of lignin and BADGE and hy@LCSs through subsequent surface cross-linking. Hy-LCSs20 (20\u2009wt% BADGE) shows stability in pH 12 alkali and acetone/water, while hy@LCSs70 exhibited unprecedented alkaline resistance up to pH 14, far exceeding the highest reported value of pH 12 for lignin colloidal spheres to date. Critically, BADGE incorporation preserved monodispersity of both hy-LCSs20 and hy@LCSs70, enabling precise size control without compromising uniformity. After centrifugation to form ordered structures, both hy-LCSs20 and hy@LCSs70 reflect specific wavelengths with tunable colors, overcoming key barriers in lignin valorization.\n\nID: 42402949\nTitle: Toxicokinetics and Toxicological Implications of Eco- and Bio-Corona Formation on Micro- and Nanoplastics in Aquatic Systems.\nAbstract: Microplastics and nanoplastics are environmentally transformable interfaces rather than static particulate debris. After release into aquatic systems, photo-oxidation, mechanical abrasion, fragmentation, and biofilm-associated aging modify their surface chemistry, morphology, polarity, and reactivity. Simultaneously, natural organic matter, humic substances, extracellular polymeric substances, proteins, lipids, and microbial products adsorb onto plastic surfaces, forming eco-coronas that regulate aggregation, colloidal stability, contaminant partitioning, and desorption behavior. A central unresolved question is how eco-corona-coated particles are remodeled after organismal entry, how environmental coronas are exchanged into bio-coronas within mucus, gut, gill, and tissue microenvironments, and how these dynamic interfaces control the toxicokinetics of coexisting pollutants. This review synthesizes current evidence to define when weathered microplastics and nanoplastics act as vectors, sinks, amplifiers, or neutral carriers of co-pollutants. We emphasize internal exposure, bioaccessibility, residence time, and tissue distribution rather than nominal water concentrations or adsorption capacity alone. Classical modeling indicates that, for many hydrophobic organic contaminants, chemical flux from natural prey, sediments, and organic matter may exceed that from ingested plastics under typical environmental conditions, requiring scenario-specific interpretation. However, this logic should not be generalized to antibiotics, pharmaceuticals, metals, and per- and polyfluoroalkyl substances, whose interactions may depend on electrostatics, ionization, hydrogen bonding, cation bridging, corona chemistry, and gut-phase desorption. We propose a predictive framework linking plastic aging, eco-corona formation, bio-corona remodeling, partitioning/desorption kinetics, uptake, retention, translocation, and organism-level outcomes. Finally, within an explicitly aquatic scope, we outline minimum reporting requirements to improve comparability, mechanistic interpretation, and risk relevance in microplastic-mixture toxicology, including clearer reporting of particle-size class, size distribution, hydrodynamic diameter after corona formation, and size-dependent uptake or translocation outcomes.\n\nID: 42402780\nTitle: Dynamic Risk Profiling of Polylactic Acid-Based Food Packaging: From Migration-Derived Toxicity Biomarkers to Green Technology-Driven Safety Optimization.\nAbstract: Polylactic acid (PLA) has emerged as a pivotal biodegradable alternative to petroleum-based plastics, playing a critical role in mitigating global plastic pollution. However, its overarching \"green\" reputation often obscures latent food safety concerns. Under complex thermal and humid storage conditions, PLA packaging is highly susceptible to in-situ degradation, precipitating the release of microplastics (MPs) and low-molecular-weight migrants-such as oligomers and functional additives-directly into food matrices. This review critically assesses these often-overlooked ingestion risks and their chronic health implications. By systematically linking PLA synthesis pathways and microstructural degradation mechanisms to dynamic migration behaviors, we delineate the specific toxicological pathways activated by these migrants. Although synthesized primarily via ring-opening polymerization to ensure stability, PLA undergoes hydrolysis in food-contact environments. Emerging toxicological evidence robustly correlates these migratory degradation intermediates with severe physiological disruptions, including intestinal barrier dysfunction, systemic oxidative stress, and immune dysregulation. Consequently, current regulatory frameworks-which predominantly focus on macroscopic material disintegration-are insufficient to address the complex biochemical toxicity of intermediate degradation products. To bridge this gap, this review evaluates sustainable risk mitigation strategies, advocating for the establishment of strict, specific migration limits (SMLs). Ultimately, we emphasize the urgent necessity for a paradigm shift toward active \"Safety-by-Design\" frameworks, ensuring that the ecological benefits of biodegradable packaging are not achieved at the expense of human dietary health.\n\nID: 42402713\nTitle: Systemic histopathological responses to nanoplastic exposure: A review of cellular toxicity and organ-level pathology in mammalian systems.\nAbstract: Nanoplastics (NPs), a subfraction of microplastics smaller than 1\u2009\u03bcm, are increasingly recognized for their ability to cross biological barriers and induce organ-level toxicity; however, their systemic histopathological effects remain fragmented across individual studies. This review summarizes current in vivo mammalian evidence on NP-induced cellular toxicity and organ-specific histopathological changes based on a structured literature search of PubMed, Scopus, and Web of Science covering studies published between 2000 and 2024. The findings were narratively organized by organ system. Across the nervous, respiratory, gastrointestinal, hepatobiliary/renal, and reproductive systems, NPs consistently induce common pathological signatures, including immune cell infiltration, apoptosis, fibrosis, epithelial barrier disruption, and ultrastructural organelle damage. These lesions indicate conserved mechanisms involving oxidative stress, inflammatory signaling, impaired cellular homeostasis, and organ-organ crosstalk, such as gut-liver and hepato-renal interactions, which may amplify systemic toxicity. Collectively, the evidence demonstrates that nanoplastics act as system-wide toxicants capable of multi-organ histopathological disruption, distinct from larger microplastics or other nanoparticles, underscoring the need for further mechanistic and pathology-driven evaluation.\n\nID: 42402351\nTitle: Prenatal Bisphenol A Exposure and Sex-Differentiated Childhood BMI Over Time: A Longitudinal Korean Cohort Study.\nAbstract: Prenatal exposure to bisphenol A (BPA), an endocrine-disrupting chemical, may influence childhood obesity. Evidence on sex-specific effects remains inconsistent. We analysed 528 mother-child pairs from a Korean birth cohort. Maternal urinary BPA concentrations were measured during mid-pregnancy. Children's BMI and BMI Z-score were assessed at ages 2, 4, 6, 8, and 10\u2009years. Associations were estimated using linear and mixed-effects models, stratified by sex and adjusted for maternal and child covariates. The mean maternal BPA concentration was 2.3\u2009\u03bcg/g creatinine. BPA exposure was positively associated with BMI and BMI Z-score in boys but negatively associated in girls. At age 10, this divergence was most apparent. Mixed-effects models showed a 0.13\u2009kg/m2 (95% CI: 0.01, 0.25) increase in BMI among boys and a 0.20\u2009kg/m2 (95% CI: -0.32, -0.08) decrease among girls per 1-unit increase in log-transformed BPA. Similar patterns were observed for BMI Z-score. Prenatal BPA exposure exhibited sexually dimorphic associations with BMI from early childhood to age 10. These findings underscore the importance of considering sex-specific effects in environmental health research and support policies to reduce BPA exposure during pregnancy.\n\nID: 42402281\nTitle: Phenacetin inhibited but acetaminophen stabilized partial nitrification/anammox system: Studies on microbial metabolism and resistance genes in biofilm and plastisphere.\nAbstract: Partial nitrification (PN) inhibitors, such as phenacetin (PNCT) and acetaminophen (APAP), ensure a stable nitrite supply for anaerobic ammonium oxidation (anammox). But the unknown impact of inhibitors on anammox limit the application of inhibitors. In addition to the biofilm carriers used in biological nitrogen removal systems, microplastics (MPs) (a type of emerging contaminants) are the common substrate for microbial colonization, even enriched resistance genes (RGs). This research compared the effects of 0.5, 1 and 5\u202fmg/L PNCT or APAP on partial nitrification-anammox (PN/A) biofilm and plastisphere. 1\u202fmg/L PNCT inhibited the nitrogen removal functional bacteria (Nitrosomonas, Candidatus Kuenenia, Candidatus Brocadia and Nitrospira), resulting in the sharp deteriorated performance of PN/A system. 5\u202fmg/L PNCT inhibited multiple metabolism pathways, resulting in the absence of electrons and energy supply of microorganisms. 0.5-1\u202fmg/L APAP maintained the stable operation of PN/A system. Nitrospira abundances declined from 2.8% to 1.1% after 0.5\u202fmg/L APAP exposure. But 5\u202fmg/L APAP inhibited the abundance of amoA and the production of extracellular polymeric substances, which caused the slight fluctuation of PN/A performance. PN inhibitors did not cause the sharp increase of most RGs in biofilm and water. However, MPs exhibited the huge capacity of enriching RGs, which should be removed. This study proposed that 0.5\u202fmg/L of APAP was suitable for the PN/A system to control dosage for practical application.\n\nID: 42402280\nTitle: A wood-derived nanocellulose aerogel developed by optimized freeze-drying for adsorbing microplastics and dyes.\nAbstract: A wood-derived aerogel with charged functional groups and unidirectional pores was prepared for microplastics and dyes adsorption. The unidirectional freezing combined with the SiC-assisted microwave heating was employed to achieve the optimization of freeze-drying (FD). The results demonstrated that the optimized FD strategy could save the drying time by more than 43%. Meanwhile, this strategy imparted ordered pores in the aerogel, thereby improving the mechanical property. The prepared aerogel showed robust performance across a broad range of pH values and had high maximum adsorption capacities of 558.37, 433.13, and 863.35\u202fmg\u00b7g-1 for microplastics, methylene blue, and Congo red, respectively. Moreover, the aerogel exhibited notable recyclability over 10 cycles, and had the ability to simultaneously remove PM plus dyes in binary pollutant systems. The research results provide a promising pathway for the sustainable utilization of forestry resource in the treatment of wastewater contaminated with microplastics and dyes.\n\nID: 42401687\nTitle: First evidence of nanoplastics in Antarctica soil.\nAbstract: Plastic contamination has become a global concern, with evidence even in remote regions like Antarctica. While macro- and microplastics have been documented in Antarctic marine ecosystems, their presence in soils - particularly submicro- and nanoplastics - remains poorly studied. This study analyses soil samples from the McMurdo Dry Valleys collected on January 8th to 28th, 2023, and reports the first detection of nanoplastics - including polypropylene, polyethylene, polyethylene terephthalate, polystyrene, polyvinyl chloride, and tyre wear particles - using thermal desorption proton transfer reaction mass spectrometry. These plastics were detected at multiple topsoil sampling sites (n\u2009=\u200913), with concentrations reaching up to 295 ng g\u207b\u00b9 with nanoplastics detected above polymer-specific method detection limits at 54% of sites (median: 26.6 ng g\u207b\u00b9). They were also detected at lower concentrations in deeper soil layers (>\u200920\u00a0cm; n\u2009=\u20094), where nanoplastics were present at 50% of the sampled sites (median: 1.95 ng g\u207b\u00b9). Lagrangian particle dispersion model FLEXPART suggested seasonal deposition patterns, with inputs from both local sources and long-range atmospheric transport. This evidence shows that soils in one of Earth's most pristine environments are not exempt from plastic contamination, with the reported concentrations providing a crucial baseline for global pollution assessments. These findings also highlight the urgent need to study plastic fate, transport, and ecological impacts in polar regions.\n\nID: 42401183\nTitle: Multi-biomarker evidence for ecotoxicological risk evaluation and management implications of DEHP-polyethylene co-exposure in saline soils.\nAbstract: The widespread application and residual accumulation of polyethylene (PE) agricultural films in saline soils have contributed to the co-occurrence of PE particles and plasticizers such as di-(2-ethylhexyl) phthalate (DEHP). Although the environmental presence of these agricultural film components is recognized, their combined ecological risks and the subsequent management challenges they pose remain poorly understood. The present study evaluated the comprehensive toxicity effects and ecotoxicological risk implications of DEHP alone and in co-exposure with PE on earthworms within a salinized soil environment using a multi-biomarker evaluation approach. The results revealed that both treatments induced oxidative stress, DNA damage, tissue damage, and molecular responses potentially linked to growth and reproduction. Notably, DEHP\u00a0+\u00a0PE co-exposure induced stronger comprehensive toxicity effects than DEHP alone in a concentration-dependent manner under the tested salinized soil conditions. To elucidate the underlying pathways and identify potential early-warning indicators for soil monitoring, transcriptomics and molecular docking were employed. Transcriptomic profiling indicated that solitary DEHP exposure primarily disrupted digestive metabolism and cellular processes. In contrast, co-exposure to DEHP and PE significantly impaired neural and vascular development pathways. Molecular docking analysis further supported these findings by illustrating the specific binding interactions of DEHP with key target proteins. Ultimately, the current study integrates multi-level biological evidence to support ecotoxicological risk evaluation of DEHP and DEHP\u00a0+\u00a0PE co-exposure, offering potential implications for future ecological risk assessment, soil monitoring, and sustainable management of agricultural plastic residues in saline ecosystems.\n\nID: 42401169\nTitle: Reactivity and environmental fate of emerging contaminants in wastewater treatment systems: A reactive continuum framework approach.\nAbstract: Emerging contaminants (ECs), including pharmaceuticals (e.g., antibiotics) and personal care products (PPCPs), hormones, artificial sweeteners, per- and polyfluoroalkyl substances (PFAS), microplastics (MPs), and antibiotic resistance genes (ARGs), are increasingly recognized as critical pollutants in wastewater treatment systems due to their persistence, bioaccumulation potential, and toxicity. Despite advances in wastewater treatment plants (WWTPs), the removal of ECs remains limited due to compound-specific behaviour, whereby contaminants undergo adsorption onto sludge solids, partial transformation into intermediates, and phase transfer to biosolids or colloids. The coexistence of ECs in complex wastewater matrices induces competitive interactions, matrix effects, and non-linear transformation pathways, reducing predictability and treatment efficiency. In this context, this review aims to provide a mechanistic understanding of EC fate and transformation in WWTPs, linking molecular properties to variability in removal across treatment configurations. It examines transformation pathways across treatment stages, integrates advances in detection with physicochemical and biological mechanisms, and highlights limitations of conventional WWTPs in achieving complete mineralization. It further proposes a reactive continuum framework (RCF) to classify contaminants by reactivity and transformation potential, thereby improving the prediction of treatment outcomes. The implications for bioaccumulation, biotransformation, and biomagnification are assessed to link contaminant behaviour with environmental risk. The RCF provides a falsifiable, molecular descriptor-based basis for predicting EC fate that removal-efficiency metrics cannot, with direct implications for reactivity-informed regulatory design under the EU Urban Wastewater Treatment Directive and equivalent frameworks globally.\n\nID: 42401118\nTitle: Effect of UV-weathering on chronic toxicity of biodegradable mulch film microplastics to Daphnia magna: Particle versus extract exposure.\nAbstract: Biodegradable mulch films are increasingly applied as sustainable alternatives to conventional plastics. However, their ecological hazards following environmental fragmentation and aging remain insufficiently understood. In particular, how ultraviolet (UV) weathering alters particle-associated and chemically mediated toxicity of biodegradable mulch films microplastics is unclear. Here, we investigated the chronic effects (16 days) of pristine and UV-weathered mulch film microplastics (PMF and UMF, respectively) and their corresponding methanol extracts (EXP and EXU, respectively) on Daphnia magna. By integrating life-history traits, biochemical energy reserves, and transcriptional responses, we disentangled particle and extract exposure. Particle exposure was associated with mortality and broader life-history impairment in D. magna, whereas extract exposure primarily affected somatic growth and reproduction without affecting survival. UV-weathering reduced particle size and increased internal particle burden; however, UMF exposure was associated with comparatively reduced organism-level impairment relative to PMF. Under extract exposure, organism-level responses were broadly comparable between EXP and EXU, whereas EXU exhibited comparatively stronger transcriptional responses related to mitochondrial and carbohydrate metabolism-associated genes. Overall, the effects of UV-weathering were endpoint-dependent rather than reflecting a uniform increase or decrease in toxicity. Instead, UV-weathering modified biological responses differently between particle and extract exposure conditions. These findings highlight the importance of exposure-specific assessment when evaluating the environmental hazards of biodegradable microplastics.\n\nID: 42401036\nTitle: From legacy to emerging polycyclic aromatic compounds: Profiling in micro-nanoplastics emissions from plastic incineration.\nAbstract: Polycyclic aromatic compounds (PACs) are organic pollutants associated with incomplete combustion processes and connected to severe health effects. Their connection to micro-nanoplastics (MNPs) emitted as particulate matter from incineration of plastics remains poorly explored. In this study, we detected 65 Polycyclic Aromatic Hydrocarbon (PAH), oxygenated (OPAH) and nitrated (NPAH) PAC species in MNPs emitted during the incineration of three widely used plastic materials, high-density polyethylene (HDPE), polypropylene (PP) and polyvinyl chloride (PVC). MNPs were generated using the incineration exposure generation system (INEXS) and their PAC profile was offline analyzed using gas chromatography-mass spectrometry. Notably, one of the most abundant species in all three plastics was Benzanthrone, an OPAH previously associated with traffic and biomass burning emissions. MNPs emitted by PVC incineration contained emerging highly toxic PAC species such as benzo(c)fluorene, dibenzopyrenes, and 6-nitrochrysene. Our findings highlight the importance of monitoring beyond the legacy 16 EPA members which accounted only by 12%, 47%, and 41% of the associated carcinogenic potency (expressed as BaPeq), for PVC, PP and HDPE respectively. These results raise concerns for potential health implications and underscore the urgent need for further research on this new environmental challenge, MNP pollution and its association with toxic persistent pollutants.\n\nID: 42400763\nTitle: Anthropogenic microparticles and mercury co-occurrence in blue sharks from the Tropical Eastern Pacific.\nAbstract: Anthropogenic microparticles derived from synthetic polymers and industrially modified natural materials have become persistent pollutants in marine ecosystems because of their capacity to adsorb and transport other contaminants. In this study, we quantified anthropogenic microparticles (AMPs) ingestion and evaluated its relationship with total mercury concentrations (THg; liver\u2009+\u2009muscle) in 23 blue sharks (Prionace glauca) from the northern Tropical Eastern Pacific (TEP), a key corridor for global fisheries and debris transport associated with the North Pacific Garbage Patch. All individuals contained AMPs (mean\u2009\u00b1\u2009SD\u2009=\u200932\u2009\u00b1\u200937 particles per digestive tract). Most particles were\u2009<\u20095\u00a0mm, with fibers as the dominant shape (76%). Among synthetic polymers, polyethylene (PE) and polyethylene terephthalate (PET) were the most abundant. Microplastics (MPs) showed a mean abundance of 12\u2009\u00b1\u200911 particles per digestive tract, whereas more than 60% of FTIR-confirmed particles corresponded to non-plastic anthropogenic microparticles (NPAMPs), mainly cotton, rayon, and cellulose, with a mean abundance of 22\u2009\u00b1\u200927 particles per digestive tract. Generalized additive models (GAMs) identified NPAMP abundance as the strongest predictor of THg concentrations (mean\u2009\u00b1\u2009SD\u2009=\u20091.08\u2009\u00b1\u20090.43\u00a0mg\u00a0kg\u207b1), revealing a significant non-linear relationship with higher Hg levels during the hot-rainy season. These findings suggest that NPAMPs may represent, together with diet, an additional pathway associated with Hg exposure in P. glauca. Risk indices (PLI, MPDI, and PHI) indicated low-to-moderate contamination levels; however, more than half of the individuals exceeded polymer hazard thresholds (PHI\u2009>\u20091000). Given the observational design, limited sample size, and the fact that seasons were sampled in different years, the NPAMP-THg relationship should be interpreted as co-occurrence rather than direct evidence of contaminant transfer. Furthermore, because particles were quantified only in non-edible tissues, these findings cannot be directly extrapolated to seafood safety risk. Nevertheless, NPAMPs emerge as a previously under-recognized component of contaminant exposure in pelagic predators and should be incorporated into future marine monitoring frameworks.\n\nID: 42400762\nTitle: IoT-enabled FMIND pipeline with chemical validation for microplastic contamination risk assessment in bottled water under varying storage conditions.\nAbstract: Microplastic contamination in bottled drinking water is an emerging environmental and public health concern, particularly when bottles are exposed to varying storage and thermal conditions. This study introduces FMIND (fuzzy microplastic inference for detection risk), an IoT-enabled fuzzy inference framework for rapid and low-cost microplastic contamination risk assessment. Bottled water stored in PET and stainless-steel containers under sunlight, shade, and freezer conditions was evaluated using IoT sensors measuring temperature, turbidity, and total dissolved solids (TDS) before and after 30\u00a0days of storage. Statistical analysis revealed strong correlations between sensor variations and contamination-related physicochemical indicators, including turbidity (r\u2009=\u20090.861), TDS (r\u2009=\u20090.793), and temperature (r\u2009=\u20090.565) (p\u2009<\u20090.001). The FMIND fuzzy model applied 12 Sugeno rules to generate a contamination risk score (0-100), while the HFIRM-GT enhanced configuration improved classification consistency within the experimental dataset, achieving an F1 score of 0.91. Laboratory validation using FTIR spectroscopy, SEM imaging, and EDAX elemental analysis on selected high-risk samples supported the presence of polymer-associated microplastic fragments in sunlight-exposed PET bottles. The proposed framework does not directly quantify microplastics through IoT sensors; instead, it estimates contamination risk using indirect physicochemical indicators supported by laboratory validation. FMIND integrates IoT sensing, fuzzy reasoning, and chemical validation into a unified and interpretable framework for periodic bottled water contamination risk assessment. The reported predictive performance reflects evaluation within a limited experimental dataset and should be interpreted as preliminary proof-of-concept validation rather than generalized field-scale performance. The system provides a scalable and cost-effective approach that supports Sustainable Development Goal 3 (Good Health and Well-Being), Sustainable Development Goal 6 (Clean Water and Sanitation), and Sustainable Development Goal 12 (Responsible Consumption and Production).\n\nID: 42400059\nTitle: Plastic signatures in childhood: first evidence of urinary micro- and nanoplastics in primary school children from Cyprus.\nAbstract: Microplastics (MPs) and nanoplastics (NPs) have recently been detected in several human biological matrices; however, evidence in children remains limited. This exploratory study aimed to investigate the presence and concentration of urinary MPs and NPs (MNPs) in primary school children residing in Cyprus. First-morning urine samples from 29 children were analyzed using scanning electron microscopy coupled with energy-dispersive X-ray analysis (SEM/EDX), applying strict contamination-control measures and focusing on particles\u2009<\u200910\u00a0\u03bcm. Pyrolysis-GC/MS was additionally used to characterize polymer composition, identifying polyethylene (PE) and polypropylene (PP) as the predominant polymers. MNPs\u2009<\u200910\u00a0\u03bcm were detected in all samples, with concentrations ranging from 393 to 8050 particles/ml (median: 1217 particles/ml; IQR: 800-2030). Particle diameters ranged from 0.88\u00a0\u03bcm to 3.44\u00a0\u03bcm (median: 1.69\u00a0\u03bcm; IQR: 1.25-2.25\u00a0\u03bcm; minimum: 0.77\u00a0\u03bcm; maximum: 4.88\u00a0\u03bcm). No statistically significant associations were observed between MNP concentrations and body mass index (BMI)-for-age categories or hand-to-mouth behavior. Although direct comparisons with previous studies are limited due to methodological variability among studies and the lack of standardized protocols for MNP quantification in human urine, these findings provide preliminary evidence of urinary MNPs in children. Further large-scale studies using harmonized analytical approaches are needed to better characterize exposure patterns in pediatric populations.\n\nID: 42398626\nTitle: Polymer-specific hazard, more than particle abundance, shapes microplastic ecological and dietary risk profiles in a tropical mangrove estuary.\nAbstract: Microplastic contamination of tropical mangrove fisheries remains poorly quantified, and polymer-specific ecological and dietary risks are rarely integrated for West African estuaries. This study assessed microplastic abundance, polymer composition, ecological risk, and human dietary exposure in commercially important finfish and crustacean species from the Escravos Estuary, Nigeria, using stereomicroscopy, FTIR identification, toxicity-weighted indices, and ingestion-based exposure modelling. Microplastics were detected in all taxa, with a mean abundance of 4.30 \u00b1 0.76 particles g-1. Surface water averaged 20.5 \u00b1 0.7 particles L-1 (n = 2 duplicate samples), and polymer and shape profiles broadly co-occurred between water and biota. Filaments (35%) and fibres (24%) dominated, while transparent and blue particles were most common, suggesting inputs from wastewater, fishing gear, and packaging materials, with possible pigment bleaching under tropical solar exposure. Detected polymers included polyvinyl alcohol, polyacrylamides, chlorosulfonated polyethylene, polystyrene, polymethyl methacrylate, and polyamides. Toxicity-weighted indices were calculated only for polymers with published hazard scores. The mean polymer ecological risk index for water indicated Class IV (7.4 \u00d7 103), and assemblage-level BALI exceeded one. Plastic Estimated Daily Intake values, derived from gastrointestinal concentrations as conservative upper-bound estimates, ranged from 1.35-2.24 particles kg-1 bw day-1 for adults and 6.31-13.59 particles kg-1 bw day-1 for children, reflecting gastrointestinal rather than edible-tissue exposure. Toxicity-weighted risk was more strongly associated with polymer hazard than particle abundance. Despite limited spatial replication from a single wet-season survey (May 2025), the findings support polymer-informed frameworks for environmental and human exposure assessment in tropical mangrove ecosystems.\n\nID: 42398625\nTitle: Divergent impacts of microplastics and related leachates on sediment carbon and nitrogen transformation by regulating microbial communities and functions.\nAbstract: Microplastics (MPs) are recognized as potential disruptors of biogeochemical cycles. However, the differential impacts of MPs types and related leachates remain poorly understood, particularly for nitrogen-containing MPs. This study compared the variational responses in sediment carbon and nitrogen transformation to 1% aged MPs (AMPs), leachates (LMPs), washed aged MPs particles (WMPs) derived from nitrogen-containing polyamide (PA) and non-nitrogen-containing polylactic acid (PLA) under natural exposure and freeze-thaw cycles (FTCs). The results showed that the Carbon Pool Management Index (CPMI) in PLA groups was always higher than corresponding PA groups, indicating better sediment quality in the PLA groups. Under natural exposure, LPA and LPLA respectively increased CPMI by 3.4% and 93.6% due to containing biologically available organic matter. FTCs increased CPMI by 34.1% in control groups, whereas only CMPI in AMPs was higher than control groups. Besides, the PLA group reduced the nitrogen mineralization rate by possibly inhibiting the macromolecular organic matter decomposition, and might have reduced the narG/H/I and nirB/D genes, thereby indirectly maintaining the nitrification rate. While the PA group increased the nitrogen mineralization rate by possibly inhibiting the amoA/B/C genes to reduce nitrification rate and enriching ureolytic microorganisms. FTCs mitigated these disparities by intensifying microbial interactions. PLS-SEM suggested that APLA was most strongly associated with carbon and nitrogen transformation within the PLA treatments, whereas the apparent effect of APA was jointly shaped by the opposite associations of WPA and LPA. These findings provide new insights into the complex ecological effects of MPs and their leachates on sediment carbon and nitrogen transformations.\n\nID: 42398554\nTitle: Inspired by the cocktail effect to prepare porous carbon with high removal performance: the critical role of sp3-C and CO in adsorption and degradation on porous carbon.\nAbstract: Identifying the active sites for adsorption and degradation of pollutants in porous carbon is crucial for the porous carbon/persulfate (PDS) decontamination system, yet the identified active sites remain controversial. To address this issue, a porous carbon with both high adsorption capacity and efficient electron transfer (or sp2 C content) is first required, but both are mutually limited. Herein, a series of porous carbons (TPS34C-Y) was effectively prepared using a simple process that involved varying the gas atmosphere (i.e., N2, CO2, air, and steam) during the activation of the pine sawdust (PS)/triphenylphosphine oxide (TO) blends. Notably, the porous carbon fabricated at the air atmosphere and 800\u202f\u00b0C temperature (i.e., TPS34C-air) achieved the highest specific surface area (2054.09\u202fm2/g). Not only that, the adsorption capacity of bisphenol A (BPA) by TPS34C-air reached 623.23\u202fmg/g within 60\u202fmin. After coupling with PDS, the removal capacity of BPA increased to \u223c900.00\u202fmg/g, with the oxidation (i.e., degradation) removal capacity reaching \u223c261.10\u202fmg/g. Besides, sp3 C was identified as an adsorption site in a range by correlating the BPA adsorption capacity with texture properties, functional group content, sp3 C, and sp2 C. Similarly, CO can be the primary degradation site in a range, as indicated by correlations between BPA degradation capacity and sp2 C, sp3 C, sp2 C/sp3 C, CO, and CO/C-OH. Encouragingly, the TPS34C-air/PDS system was dominated by the electron transfer pathway (ETP). The present work offers considerable data for identifying adsorption and surface degradation sites in the porous carbon/PDS decontamination system.\n\nID: 42398491\nTitle: Microplastic footprints in freshwater ecosystems: Raman spectroscopy of microplastics as indicator of anthropopressure in Northeastern Poland's lakes.\nAbstract: To understand the effect of anthropopressure on microplastic contamination, a comprehensive analysis of Raman spectroscopic measurements conducted on microplastic fibers collected from the freshwater lakes located in Northeastern Poland was performed. Six of the lakes are under protection. Results indicate a diverse array of fiber types with dominant synthetic polymers: polypropylene (PP) and polyethylene terephthalate (PET), as well as numerous organic materials, including cellulose-based fibers (rayon). We found a positive relationship between the amount of microplastic fibers in surface water and the anthropopressure index (IA) calculated for each of the studied lakes. Fiber levels differed significantly between lakes located in protected (33 - 370 items per m3) and urban areas (285 - 845 items per m3). Results indicate that the isolation in protected areas does not shield lakes from airborne microfiber pollution. For five of the lakes investigated results are compared with a previously published study pointing to notable differences in microplastic concentrations detected near shore and in the central part of the lake. Methods of assessing anthropopressure are contrasted and differences in sampling approach are evaluated. Monitoring the abundance and characteristics of microplastics is required to understand their source and patterns of distribution, both of which can be affected by the level of anthropopressure.\n\nID: 42398418\nTitle: Co-contamination of hybrid microplastics and PFOA/GenX alters rhizosphere bacterial-fungal communities and root performance of Eichhornia crassipes.\nAbstract: This study investigates bacterial-fungal interactions in the rhizosphere of floating macrophytes co-contaminated by microplastics (MP) and per- and poly-fluoroalkyl substances (PFASs), and explores how MP composition influences root health and nutrient removal. Methodologically, we design a hydroponic experiment: eleven MP-composition schemes were constructed using polystyrene, polyethylene, and polypropylene (CK sequence), and Eichhornia crassipes was cultivated under these exposures. The comparison sequences included treatments with PFOA and GenX (OA and GX sequences). High-throughput sequencing of 16S rRNA and ITS genes was performed to profile rhizosphere bacterial and fungal communities. Root performance was evaluated using integrative indicators that reflect rhizosphere health and nutrient removal efficiency. The results showed that MP composition shifted bacterial and fungal phylum-compositions without altering the dominant taxa-Proteobacteria (21.77\u223c67.41%) and Bacteroidota (9.43\u223c39.60%) for bacteria and Rozellomycota (11.36\u223c82.81%) and Ascomycota (9.17\u223c48.38%) for fungi. MP diversity significantly influenced bacterial \u03b1-diversity in the OA sequence (k\u202f=\u202f0.171\u223c0.472) and fungal \u03b1-diversity in the CK sequence (k\u202f=\u202f-0.458\u223c0.087). \u03b2-diversity analysis revealed distinct bacterial and fungal response patterns to MP variation across sequences. In the GX sequence, the bacterial assembly was predominantly shaped by homogeneous selection with 50.09% contribution. MP composition also modulated bacterial-fungal co-occurrence networks, with fungal participation notably weakened under PFAS exposure. Under PFOA co-contamination, MP type acted as a module hub in the microbial network. Partial least squares path modeling (PLS-PM) showed that MP composition primarily regulated root performance via hydrochemistry, with bacterial-fungal interactions significantly affecting root performance only in the presence of PFOA (PC=-0.194). This study enhances the understanding of microbial interactions in nutrient removal and root tolerance of floating macrophytes exposed to combined MP and PFAS pollution. It also provides an exploration on utilization of floating macrophyte-based remediation, identifying MP composition as a potential factor.\n\nID: 42398416\nTitle: PLA vs PE microplastics with cadmium: Time-dependent divergent and microbial disruption of soil carbon and nitrogen cycling in medicinal plant soils.\nAbstract: Microplastics (MPs) and cadmium (Cd) co-contamination is an emerging concern in agricultural soils, but its dynamic effects on carbon (C) and nitrogen (N) cycling in medicinal plant systems remain unclear. Here, we conducted a full-growth-cycle pot experiment using Epimedium as a model plant, covering seedling (S1), vegetative (S2), and maturity (S3) stages. Polyethylene (PE) and polylactic acid (PLA) were applied at 0.01-0.15% (w/w) combined with Cd at 2\u202fmg/kg. Using 16S rRNA sequencing, PICRUSt2, and structural equation modeling, we assessed soil C/N pools, enzyme activities, bacterial communities, and functional genes. Pollution effects exhibited clear growth-stage-dependent thresholds. The strongest disturbance to C/N pools occurred at S2, with partial recovery at S3. PLA-Cd induced significantly stronger disturbances than PE-Cd, driven by fundamentally different pathways: PE-Cd effects are primarily associated with physicochemical pathways (direct enzyme inhibition), whereas PLA-Cd effects are strongly correlated with microbial community restructuring. Under PLA-Cd, keystone taxa shifted from functional genera (Sphingomonas, Flavisolibacter) to stress-tolerant Acidobacterium, and bacterial co-occurrence network modularity collapsed from 0.362 to 0.227. Predicted abundances of C-fixation, N-fixation, and nitrification genes decreased by 44.9-64.0%, forming a metabolic pattern of suppressed N input and weakened C retention. These findings propose the \"growth stage dependent response pattern\" and a \"differentiated mechanism of synergistic toxicity\", elucidating how degradable vs. non-degradable MPs exert divergent toxic effects. This challenges the common assumption that biodegradable plastics are environmentally friendly under heavy metal co-contamination.\n\nID: 42398412\nTitle: Bisphenol A degradation by Lactiplantibacillus plantarum AM employing Fenton chemistry.\nAbstract: Lactiplantibacillus plantarum, Gram-positive facultative anaerobic strain with antioxidant potential, can degrade and detoxify xenobiotic compounds. In this study, we evaluated Lpb. plantarum AM for its antioxidant properties, bisphenol A (BPA) degradation, and Lpb. plantarum AM mediated-Fenton reaction for BPA degradation. \u2264\u202f43.8 \u00b5mol BPA did not affect the growth of Lpb. plantarum AM even in glucose-deficient MRS medium. BPA at \u2265\u202f52.56 \u00b5mol significantly inhibited growth (p\u202f<\u202f0.001) of Lpb. plantarum AM and delayed transition from the logarithmic (log) phase to the stationary phase. When \u2265\u202f52.56 \u00b5mol BPA was added at 0 or 4\u202fh, the transition from log phase was delayed from 12\u202fh (control) to 16\u202fh, and at 61.32 \u00b5mol BPA further to 18\u202fh. Lpb. plantarum AM produced 1 \u00b5mol cell-associated H2O2 at 20\u202fh and >\u202f45 nmol FeII within 26\u202fh. Lpb. plantarum AM is capable of performing extracellular Fenton reactions. In the presence of FeCl3Lpb. plantarum AM caused disappearance of the characteristic BPA absorption peaks and emergence of new spectral peaks (\u223c258-265\u202fnm), suggesting BPA transformation. Functional and comparative genomics revealed genes associated with oxidativestress management, antioxidant defence, and H2O2-production, supporting the experimental observed phenotype. Overall, Lpb. plantarum AM demonstrated strong antioxidant and Fenton-driven BPA-transforming capabilities, highlighting its potential as a sustainable microbial candidate for detoxification of xenobiotic pollutants.\n\nID: 42398346\nTitle: Turning the enemy into an ally: Phytoremediation potential of Solidago canadensis L. for Cd-contaminated soil as influenced by microplastics and biochar.\nAbstract: Due to its strong tolerance to toxic metals and environmental stresses, Solidago canadensis L. exhibits a promising phytoremediation potential in regions without invasion risks (e.g., North America). However, the co-occurrence of Cd contamination and microplastics (MPs) in soils presents unprecedented challenges for remediation strategies. Using metabolomic analysis, our study first investigated the phytoremediation efficacy of S. canadensis for Cd-contaminated soil under the influences of MPs types (polyethylene terephthalate, PET; polylactic acid, PLA; polyester, PES) and dosages (0, 0.2%, and 2%; w w-1), and biochar (BC) amendment (0 and 1%; w w-1). Results revealed complex polymer- and dose-dependent effects on Cd dynamics, where PES enhanced Cd immobilization, while 0.2% PET/PLA paradoxically increased root Cd accumulation by 5.6%-13.8% despite reducing soil Cd extractability. MPs exposure induced comprehensive physiological perturbations in S. canadensis, including biomass allocation, chlorophyll degradation, micronutrient homeostasis, and profound metabolic reprogramming characterized by the upregulation of allelopathic metabolites. BC amendment effectively immobilized Cd, mitigated oxidative stress, and restored nutrient cycling by enhancing enzyme activities. Crucially, BC decreased the relative abundances of key allelochemicals by 65.3% \u00b1 14.2% through energy metabolic restructuring, while maintaining high phytoremediation efficiency. Significant triple interactions (MPs type \u00d7 MPs dose \u00d7 BC) underscored context-dependency of remediation outcomes, with biodegradable PLA exhibiting distinct ecological implications. These findings demonstrate that integrating BC amendment with S. canadensis phytoremediation offers a sustainable strategy for managing MPs-Cd co-contaminated soils within the framework of ecological security.\n\nID: 42398013\nTitle: Colonisation potential of microplastic particles containing organic pollutants by a river-isolated environmental Acinetobacter baumannii.\nAbstract: Microplastics in aquatic environments raise concern about their role as potential carriers of pathogens and organic pollutants. This study investigates the survival of the extensively drug-resistant Acinetobacter baumannii in the presence of selected priority substances including benzene derivatives (trichlorobenzene, pentachlorobenzene, and hexachlorobenzene), trifluralin, and primary polyethylene microplastics. The results indicate that the amount of adsorbed priority substances on microplastics from a mixture solution is slightly lower than the adsorption from individual solutions. Furthermore, GC/MS analysis shows that other chemicals used in plastic manufacturing can be released from microplastics into the environment over time and should be taken into account when assessing the environmental impact of microplastics. The proliferation of the environmental Sava 4 A. baumannii strain was not affected by the presence of benzene derivatives and microplastic particles at concentrations of up to 10 g/L in the water medium, and microscopy confirmed that it can colonise and form a biofilm on microplastic particles with adsorbed benzene derivatives, which demonstrates that microplastics have the potential to spread pollutants and potentially harmful bacteria over long distances and introduce them into various aquatic environments. Mikroplastika, kao sve prisutnije zaga\u0111ivalo u vodenim ekosustavima, izaziva zabrinutost zbog svoje potencijalne uloge vektora patogena i organskih zaga\u0111ivala.

Their capacity to adsorb, transport, and release contaminants has raised growing concern over mixture toxicity under realistic exposure scenarios. This review systematically examines the mechanistic basis of MNPs-mediated combined toxicity and evaluates the emerging role of network toxicology as a systems-based tool for hazard assessment. MNPs alter the bioavailability, environmental fate, tissue distribution, and intracellular delivery of associated pollutants through hydrophobic, electrostatic, and other intermolecular interactions. Carrier-mediated uptake, particularly the \"Trojan horse\"\u00a0effect, appears to be a major driver of non-additive toxicity in co-exposure systems. We then outline the core workflow of network toxicology, encompassing target identification, network construction, pathway enrichment, and experimental validation, and discuss its application in decoding mixture toxicity. Oxidative stress, inflammatory signaling, metabolic disturbance, barrier dysfunction, and programmed cell death emerge as conserved and interconnected pathways underlying synergistic multi-organ injury. These findings indicate that toxicity in complex exposure systems is governed not only by the intrinsic properties of particles or chemicals, but also by their dynamic physicochemical and biological interactions. We further assess current advances and limitations in network toxicology and propose a next-generation risk assessment (NGRA)-oriented framework to support mechanism-based risk assessment and regulatory decision-making. Although current evidence is dominated by binary, high-dose laboratory studies, network toxicology offers strong potential as a new approach methodology (NAM) for predictive evaluation of environmentally relevant mixtures. Future priorities include standardized multi-omics integration, dose-time-response modeling, human-relevant validation, and regulatory translation.\n\nID: 42323136\nTitle: Chronic bisphenol A exposure impairs cognitive function in male mice associated with NLRP3 inflammasome-driven pyroptosis and gut microbiota dysbiosis along the microbiota-gut-brain axis.\nAbstract: The microbiota-gut-brain axis (MGBA) is a critical bidirectional communication system governing cognitive function and intestinal homeostasis. Despite growing evidence linking environmental chemicals to neurological disorders, the mechanisms underlying bisphenol A (BPA)-induced cognitive deficits remain poorly understood. Here, we demonstrate that chronic BPA exposure may induce cognitive impairment in male offspring through disruption of the MGBA, specifically via upregulation of the NLRP3 inflammasome/pyroptosis-related markers. Gravid Kunming mice received BPA (0, 2, 20, or 200\u202f\u00b5g/kg body weight/day) in drinking water until weaning; their male offspring were then orally administered identical doses for nine weeks. Behavioral tests revealed significant deficits in short- and long-term memory following high-dose (200\u202f\u00b5g/kg) BPA exposure. Mechanistically, high-dose BPA reduced hippocampal neuron density, compromised ileal barrier integrity, and induced dysbiosis characterized by decreased \u03b1-diversity (Chao1, ACE, Shannon; P\u202f<\u202f0.05) and an elevated Firmicutes/Bacteroidota ratio. LEfSe analysis identified increased abundance of potentially pro-inflammatory genera at 200\u202f\u00b5g/kg. Crucially, high-dose BPA upregulated the expression of NLRP3, ASC, Caspase-1, GSDMD, and IL-18 in both the hippocampus and ileum, alongside elevated serum TNF-\u03b1 and IL-18, indicating systemic inflammation. Correlation analyses further linked specific microbial shifts to pyroptosis markers and cognitive decline. Collectively, our findings establish that chronic BPA exposure may triffer gut dysbiosis and barrier dysfunction, leading to NLRP3 inflammasome activation and pyroptotic cell death in both the gut and brain, ultimately impairing cognition. These results underscore the neurotoxic risk posed by BPA and provide a mechanistic rationale for stricter regulatory controls on its use in food-contact materials.\n\nID: 42260891\nTitle: Multi-scale analysis reveals key targets mediating BPA-induced sensorineural hearing loss.\nAbstract: The mechanism of bisphenol A (BPA) on sensorineural hearing loss (SNHL) remains undefined. This study investigates BPA's toxic mechanism on SNHL. ProTox database was performed to analyze the toxicity of BPA. Intersection genes were screened using network toxicology, and causal genes associated with SNHL were identified through Mendelian randomization. The ligand-protein binding activity was validated through molecular docking and dynamic simulation. BPA showed a toxicity classification of Class 4, with toxicological profiles involving the blood-brain barrier, mitochondrial membrane potential, and estrogen receptor alpha. A total of 92 BPA target genes were found to be related to SNHL. These were enriched in potassium ion channel processes and MAPK, PI3K-Akt pathways. Two-sample Mendelian randomization identified 3 causal genes, with small effect sizes: MANBA (odds ratios [OR]\u2005=\u20050.950, P\u2005=\u2005.009), PDE6D (OR\u2005=\u20051.055, P\u2005=\u2005.001), vascular endothelial growth factor A (OR\u2005=\u20051.030, P\u2005=\u2005.022). Molecular docking with BPA revealed minimum binding free energies of -8.1, -6.7, and -6.1 kcal/mol; MANBA-BPA binding was stable in dynamics simulations. BPA can exert toxic effects on SNHL through potassium channel related processes, as well as MAPK and PI3K-Akt signaling pathways. MANBA, PDE6D, and vascular endothelial growth factor A also play key mediating roles in this process.\n\nID: 42172709\nTitle: Micro- and nanoplastics in the central nervous system: Transport pathways, neurotoxicity, and implications for brain disorders.\nAbstract: Micro- and nano-plastics (MNPs) are widely distributed across global ecosystems and have been extensively detected in human tissues, including the brain. The levels of MNPs are highly correlated with the occurrence of various brain disorders, suggesting the potential central nervous system (CNS) toxicity of MNPs. In this review, we summarize the major circuits by which MNPs may transport into and out of the CNS, including blood-brain barrier crossing, nasal-to-brain routes, and glymphatic system transport. Small-sized MNPs are difficult to eliminate from the brain, which may explain why MNPs may accumulate in the brain. We further discuss the potential neurotoxic effects of MNPs, such as inducing synaptic and neuronal injury, promoting neuroinflammation, dysregulating the neuroendocrine system, and modulating the gut-brain axis. MNP-induced CNS toxicity follows a pattern in which increased susceptibility occurs before direct toxicity. We also review evidence that MNPs, together with environmental and genetic factors, may synergistically contribute to cognitive impairment in Alzheimer's disease, motor dysfunction in Parkinson's disease, and depression- and anxiety-like behaviors. Prenatal exposure to MNPs might induce autism spectrum disorder-related phenotypes in offspring. MNPs could also obstruct cerebral vessels and trigger acute cerebrovascular diseases, as well as promote the entry of viruses such as SARS-CoV-2 into the CNS, thereby increasing the occurrence of neurological symptoms. Finally, this review discusses physical, pharmacological, and plastics substitution interventions designed to regulate MNPs transport in the brain and enhance neuroprotection, thereby reducing CNS toxicity of MNPs.\n\nID: 42119735\nTitle: Preliminary evidence of polyvinyl chloride microplastics inducing ferroptosis in the cerebral cortex of ducks.\nAbstract: Ferroptosis, a type of regulated cell death, is frequently observed in mammalian brain cortical injuries and diseases linked to iron metabolism disorders. Recent evidence suggests that microplastic exposure may trigger such ferroptosis-related pathologies. However, the mechanism and impact of ferroptosis-induced cerebral cortex damage in waterfowl due to microplastic exposure remain unclear. In this study, Muscovy ducks were divided into three groups receiving: pure water, 1\u202fmg\u00b7L\u207b\u00b9\u202fpolyvinyl chloride microplastics (PVC-MPs), or 10\u202fmg\u00b7L\u207b\u00b9\u202fPVC-MPs for two months. This study suggests that PVC-MPs may accumulate in the duck cerebral cortical tissue, where they disrupt blood-brain barrier (BBB) integrity as manifested by ultrastructural damage and significant downregulation of tight junction protein levels (ZO-1, Occludin, and Claudin-5). Moreover, PVC-MPs exposure induced histopathological and nuclear ultrastructural damage, along with oxidative stress and excessive iron accumulation, both hallmarks of ferroptosis. Specifically, PVC-MPs triggered mitochondrial cristae fragmentation and shrinkage, as well as lipid peroxidation accumulation, evidenced by elevated MDA levels. Western blot analysis confirmed ferroptosis through significant downregulation of SLC7A11, GPX4, and FTH1, and upregulation of COX2. In conclusion, this study suggests that PVC-MPs may accumulate in the duck cerebral cortex, where they disrupt BBB integrity and induce histopathological damage, as well as disturb redox homeostasis and trigger ferroptosis, ultimately leading to neuronal injury.\n\nID: 42107909\nTitle: Embryonic exposure to Bisphenol S causes long-term social behavioural alterations in adult zebrafish (Danio rerio).\nAbstract: Bisphenol S (BPS), a widely used substitute for Bisphenol A (BPA), is frequently detected in aquatic environments and has raised concerns due to its potential neurotoxic effects. Despite being marketed as a safer alternative, the long-term impacts of BPS on neural function and behaviour remain poorly understood. This study investigated whether embryonic exposure to environmentally relevant concentrations of BPS induces persistent neurobehavioural, neurochemical, and molecular alterations in adult zebrafish (Danio rerio). Embryos were exposed to an environmentally relevant concentration of BPS (30 \u00b5g/L) from 4 to 120 h post-fertilization (hpf) and subsequently reared in clean water until 6 months of age. Adult behavioural assessments revealed that BPS-exposed fish exhibited significant deficits in social affiliation, spending less time in the conspecific zone during group preference testing. However, shoaling behaviour and anxiety-like responses in the novel tank test, including swimming speed and zone preference, remained unaffected. Neurochemical analysis showed a significant reduction in brain dopamine levels, while serotonin (5-HT) and acetylcholine (ACh) levels were unchanged. Oxidative damage was corroborated by a significant elevation of brain lipid peroxidation (LPO) following embryonic BPS exposure. Molecular profiling of adult brain tissues revealed alterations in genes associated with oxidative stress (gpx1a), apoptosis (p53, bax, casp3), neuroinflammation (tnf-\u03b1, il1b, ngfb), and neurotransmission, particularly within serotonergic (slc6a4b, htr1d, htr2b) and cholinergic (chata) pathways. These findings indicate that embryonic BPS exposure leads to persistent neurochemical and transcriptional changes that selectively impair adult social behaviour without broadly affecting anxiety or locomotion. These observations underscore the potential neurodevelopmental toxicity of BPS and the urgent need to re-evaluate its safety in aquatic environments.\n\nID: 42098161\nTitle: Gut microbiota-GABA axis dysregulation underlies polystyrene microplastic (PS-MP) neurotoxicity in rainbow trout: a role for oxidative stress and blood-brain barrier disruption.\nAbstract: Microplastics (MPs) threaten aquatic ecosystems and pose potential risks to organismal health through bioaccumulation in aquatic species. This study reveals that 14-day exposure to 5\u2009\u03bcm polystyrene microplastics (PS-MPs) (500\u2009\u03bcg/L) induces neurocognitive impairment in rainbow trout (Oncorhynchus mykiss), a globally consumed aquaculture species. MPs accumulated in brain and gut tissues, causing blood-brain barrier structural alterations, intestinal mucosal damage, and oxidative stress. Multi-omics analysis revealed associations between gut microbiota dysbiosis (reduced Ralstonia, increased Acinetobacter) to suppressed neuroactive pathways, particularly GABA synthesis and transport. Downregulation of monocarboxylate transporters (mct1/2) and GABA-related enzymes (GAD1/2) disrupted gut-to-brain GABA homeostasis, neurobehavioral deficits. These findings establish the gut microbiota-GABA axis as a critical mediator of MPs neurotoxicity, highlighting risks to seafood safety and necessitating urgent regulation of microplastic contamination in aquatic food chains.\n\nID: 42085735\nTitle: Bisphenol A potentiates ischemia-reperfusion-induced endothelial and blood-brain barrier dysfunction associated with CX3CL1-CX3CR1 signaling.\nAbstract: Bisphenol A (BPA) is a widely distributed environmental contaminant; however, its potential role in modulating ischemic neurovascular injury remains unclear. We applied an integrative approach combining network toxicology, Mendelian randomization, molecular docking, and single-cell transcriptomics to identify BPA-responsive targets relevant to ischemic stroke. CX3CL1 was prioritized based on network centrality, genetic association with stroke risk, and endothelial enrichment in post-ischemic brain tissue. Functional validation was performed in bEnd.3 brain endothelial cells and an endothelial-astrocyte Transwell blood-brain barrier (BBB) co-culture model subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Under normoxic conditions, BPA (50 and 100\u202f\u03bcM) did not markedly reduce cell viability; however, it significantly aggravated OGD/R-induced injury. BPA increased endothelial apoptosis (10.1% and 21.2% vs. 4.6% under OGD/R alone), elevated CX3CL1 protein expression (1.71- and 2.28-fold vs. control), increased BAX, and reduced Bcl-2 levels. Tight junction proteins were substantially decreased (claudin-5: 0.49 and 0.24; ZO-1: 0.46 and 0.23 relative to control), accompanied by reduced transendothelial electrical resistance and increased FITC-dextran permeability. Pharmacological inhibition of CX3CR1 using AZD8797 (0.5\u202f\u03bcM) partially attenuated BPA-exacerbated apoptosis, tight junction loss, and barrier hyperpermeability without significantly altering CX3CL1 expression. Collectively, these findings suggest that BPA potentiates ischemia-reperfusion-associated endothelial and barrier dysfunction, accompanied by changes in CX3CL1-CX3CR1-related signaling, and support a potential role for environmental toxicants as modifiers of ischemic neurovascular vulnerability.\n\nID: 42059992\nTitle: Micro- and Nanoplastics in the Human Brain: Mechanistic Plausibility, Translational Challenges, and Links to Neurological Disease Trends.\nAbstract: The exponential growth in plastic production since the mid-twentieth century has led to the pervasive presence of micro- and nanoplastics (MNPs) across ecosystems and human exposure pathways, coinciding with a rising global burden of neurological disorders. Increasing evidence demonstrates that MNPs are not confined to peripheral tissues but can accumulate even in the human brain, raising concerns about their potential contribution to neurological disease. This structured review synthesizes global trends in plastic production, environmental MNP burden, and human exposure, together with emerging data on brain accumulation, entry pathways, neurotoxic mechanisms, and key translational challenges. We present evidence showing that MNPs may cross brain barriers via multiple routes, including the blood-brain barrier, blood-cerebrospinal fluid barrier, olfactory, and circumventricular pathways, particularly under conditions of barrier vulnerability. Experimental studies reveal that once in neural tissue, MNPs may disrupt synaptic function, mitochondrial homeostasis, autophagy, and redox balance, while activating neuroinflammatory and gut-brain axis-mediated pathways. These mechanisms intersect with disease-relevant processes implicated in multiple neurological disorders whose global prevalence and societal burden have sharply increased over recent decades, including stroke, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, mood disorders, and neurodevelopmental conditions. Despite growing mechanistic plausibility, translational and human epidemiological evidence remains limited by methodological heterogeneity, a lack of standardized detection methods, and the absence of longitudinal clinical data/studies.

Exposure to contaminants such as bisphenol A (BPA), phthalates, polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) during these critical windows can reprogram endocrine and neural circuits, resulting in persistent behavioral alterations. This review synthesizes mechanistic evidence from animal models and epidemiological studies linking developmental EDC/POP exposure to attention deficits, impulsivity, anxiety and altered reward sensitivity-phenotypes defined here as addiction vulnerability (addiction-relevant endophenotypes) rather than clinically diagnosed substance-use disorder (SUD). We propose a two-hit, adverse outcome pathway (AOP)-informed model in which prenatal EDC/POP exposure induces endocrine-related perturbations that prime reward and stress circuitry. Subsequent exposure to psychoactive drugs and/or chronic stress then acts on these sensitized systems to increase the probability of maladaptive reinforcement learning and impaired behavioral control. Mechanistically, early-life exposures disrupt thyroid and sex-steroid signaling, dysregulate the hypothalamic-pituitary-adrenal axis, and alter dopaminergic, serotonergic, and glutamatergic neurotransmission with additional modulation by epigenetic reprogramming, oxidative stress, and neuroinflammation. Human cohort studies consistently associate prenatal BPA and phthalate exposures with adverse neurobehavioral and externalizing symptoms in children, supporting this framework while underscoring the limited availability of longitudinal data linking early exposure to SUD outcomes. Integrating these findings within an AOP perspective highlights the importance of developmental timing, sex, dose, genetic background, and co-exposures, and supports risk-assessment strategies that account for sequential environmental and drug exposures.\n\nID: 42056810\nTitle: Polystyrene nanoplastic-encapsulated extracellular vesicles promote blood-brain barrier breakdown and accumulate in the brain.\nAbstract: Nanoplastics (NPs) may disrupt the blood-brain barrier (BBB), but the underlying cellular routes remain unclear. Here, we tested whether extracellular vesicles (EVs) enhance endothelial uptake, intracellular accumulation, and barrier disruption by polystyrene NPs (PSNPs). Human umbilical vein endothelial cells (HUVECs) were exposed to free PSNPs (100\u202f\u03bcg/mL) or PSNP-encapsulated EVs (PSNP-EVs; 1\u202fmg/mL EV protein) for 24\u202fh, with vehicle controls, and barrier function was evaluated in endothelial monolayers using transendothelial electrical resistance (TEER) and permeability assays. Notably, EV encapsulation prolonged intracellular retention of PSNPs and reduced cellular clearance compared with free PSNPs, with signals persisting up to 12\u202fh, whereas free PSNPs peaked at 4\u202fh and declined thereafter. In human endothelial monolayers, PSNP-EVs produced a larger decline in TEER than free PSNPs, resulting in a 2.8-fold greater TEER decline, and promoted macromolecule-permeable paracellular transport, selectively increasing 4-kDa (1.38-fold) and 40-kDa (3.07-fold) dextran permeability while leaving sodium fluorescein largely unchanged. PSNP-EV exposure reduced occludin and ZO-1 expression to 47.6% and 60.8% of control levels, respectively, and disrupted their continuous junctional localization, indicating destabilization of the occludin-ZO-1-actin scaffold. Pharmacologic inhibition of dynamin-mediated endocytosis with dynasore reduced EV uptake by 69.3% and prevented PSNP-EV-induced TEER loss. In vivo imaging further revealed brain accumulation and persistence of administered PSNP-EVs. Collectively, these results indicate that EVs promote sustained accumulation of nanoscale plastics within endothelial cells and the brain, concomitant with increased macromolecular paracellular permeability of the BBB and a heightened neurovascular risk.\n\nID: 41955522\nTitle: Nanoplastics and Neurodegeneration: A Roadmap From Mechanism to Causation.\nAbstract: Nanoplastics are ubiquitous by-products of global plastic production and have emerged as a potentially consequential yet insufficiently defined threat to health. Recent studies have revealed that these synthetic particulates can cross the blood-brain barrier, accelerate amyloid aggregation, impair microglial clearance, hijack the gut-liver-brain axis, and drive neuroinflammation-mechanisms central to neurodegeneration in Alzheimer's and Parkinson's disease. In addition, anionic nanoplastics can induce vascular endothelial leakiness, thereby harboring a paracellular route for their systemic and cerebral access. Yet causality remains unproven in implicating nanoplastics for neurodegeneration in the absence of standardized human exposure data, mechanistic specificity, and epidemiological evidence, especially considering the supra-environmental doses employed. Here, we synthesize current knowledge, examine barriers to causal understanding, and propose a roadmap to advance this emerging scientific frontier of great public concern and inform future strategies for sustainable materials innovation.\n\nID: 41863493\nTitle: A Physiological Microfluidic Blood-Brain-Barrier Model for In Vitro Study of Nanoparticle Trafficking and Accumulation.\nAbstract: Although the blood-brain barrier (BBB) restricts passage of most molecules, various naturally occurring and synthetic nanoparticles (NPs) are nonetheless found within the brain parenchyma. To study the mechanisms underlying this phenomenon, we developed a microfluidic BBB model (mBBB) using human cerebral microvascular endothelial cells (HCMECs) in direct contact with primary human astrocytes and pericytes within a physiologically relevant extracellular matrix. The horizontal architecture enables high-resolution imaging across the full barrier interface and allows direct assessment of nanoparticle transport and accumulation. This in vitro platform recapitulates key features of the BBB, including selective permeability, junctional protein expression, and receptor-mediated uptake pathways. Using this system, the trafficking and accumulation of structurally distinct nanoparticles, including liposomes, nanoplastics, and extracellular vesicles (EVs), were compared. Among these, heterologous EVs exhibit the highest transport efficiency. Analysis of nanoparticle properties suggest that ligand presentation and membrane composition, rather than size or stiffness, primarily govern BBB penetration. The mBBB platform provides a high-throughput, imaging-based framework to systematically interrogate nanoparticle trafficking across the BBB and offers a translational tool for both drug delivery and neurotoxicity screening.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration.\n  --- END ACTUAL ABSTRACT FOR 42294809 ---\n\n- ERROR: You cited ID: 42397579 for the quote: \"Carrier-mediated uptake, particularly the 'Trojan horse' effect, appears to be a major driver of non-additive toxicity in co-exposure systems.\"\n  FACT: Strict Misquote Detected!

Their capacity to adsorb, transport, and release contaminants has raised growing concern over mixture toxicity under realistic exposure scenarios. This review systematically examines the mechanistic basis of MNPs-mediated combined toxicity and evaluates the emerging role of network toxicology as a systems-based tool for hazard assessment. MNPs alter the bioavailability, environmental fate, tissue distribution, and intracellular delivery of associated pollutants through hydrophobic, electrostatic, and other intermolecular interactions. Carrier-mediated uptake, particularly the \"Trojan horse\"\u00a0effect, appears to be a major driver of non-additive toxicity in co-exposure systems. We then outline the core workflow of network toxicology, encompassing target identification, network construction, pathway enrichment, and experimental validation, and discuss its application in decoding mixture toxicity. Oxidative stress, inflammatory signaling, metabolic disturbance, barrier dysfunction, and programmed cell death emerge as conserved and interconnected pathways underlying synergistic multi-organ injury. These findings indicate that toxicity in complex exposure systems is governed not only by the intrinsic properties of particles or chemicals, but also by their dynamic physicochemical and biological interactions. We further assess current advances and limitations in network toxicology and propose a next-generation risk assessment (NGRA)-oriented framework to support mechanism-based risk assessment and regulatory decision-making. Although current evidence is dominated by binary, high-dose laboratory studies, network toxicology offers strong potential as a new approach methodology (NAM) for predictive evaluation of environmentally relevant mixtures. Future priorities include standardized multi-omics integration, dose-time-response modeling, human-relevant validation, and regulatory translation.\n  --- END ACTUAL ABSTRACT FOR 42397579 ---\n\n- ERROR: You cited ID: 42356279 for the quote: \"these findings indicate that acute co-exposure to BPA and PE microplastics elicits early antioxidant activation and selective synaptic-related transcriptional changes in the PFC\"\n  FACT: Strict Misquote Detected!

Polyethylene (PE), widely used in food-contact materials, can carry bisphenol A (BPA), an endocrine disruptor with oxidative and neuroactive properties. Although both MPs and BPA can cross biological barriers, their acute effects on the prefrontal cortex (PFC) remain poorly understood. The aim of the study was to evaluate the acute impact of orally administered free BPA, free MPs, and BPA adsorbed onto PE MPs (PE-BPA) on oxidative stress, inflammation, and gene expression in the PFC of Wistar rats. Animals received a single dose of BPA, PE-BPA, PE alone, or vehicle. Methods: Biochemical and transcriptional analyses were performed to evaluate the antioxidant and inflammatory responses as well as the potential changes in synaptic-related gene expression. Results: BPA-containing treatments produced selective early molecular responses. Catalase (CAT) and glutathione S-transferase (GST) activities were significantly increased in the PE-BPA group, with GST being also elevated in the BPA-alone group, whereas superoxide dismutase (SOD), myeloperoxidase (MPO), and malondialdehyde (MDA) levels did not significantly change. Transcriptional analyses revealed upregulation of the antioxidant genes Nrf2 and CAT in the PE-BPA group. Co-exposure to BPA and MPs also altered synaptic markers, including decreased brain-derived neurotrophic factor (BDNF) and Sert along with increased Nr2A expression, while inflammatory gene expression remained unaffected. Conclusions: These findings indicate that acute co-exposure to BPA and PE microplastics elicits early antioxidant activation and selective synaptic-related transcriptional changes in the PFC, suggesting that MPs may modulate BPA-associated molecular responses in the brain.\n  --- END ACTUAL ABSTRACT FOR 42356279 ---\n\n- ERROR: You cited ID: 42056810 for the quote: \"In human endothelial monolayers, PSNP-EVs produced a larger decline in TEER than free PSNPs...

Chronic exposure to these contaminants triggers oxidative stress and mitochondrial dysfunction, forming a feed-forward mechanism that sustains neuroinflammation and neurodegeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe convergence of environmental MNP and BPA exposure on the lysosomal-autophagy pathway represents a critical mechanism of neurotoxic damage. Evidence demonstrates that $\\alpha$-synuclein, the protein central to PD, misfolds upon binding to MNP surfaces, transitioning from an open helical conformation to an aggregated state. The internalization of these plastic particles triggers significant lysosomal dysfunction. Specifically, internalized NPs accumulate in endolysosomal systems, inducing lysosomal membrane permeabilization (LMP) and releasing lysosomal enzymes into the cytosol, which precipitates cellular death pathways and worsens $\\alpha$-synuclein pathology. Similarly, BPA and its derivatives exacerbate these pathways by promoting oxidative stress and inducing mitochondrial dysfunction. The interaction between these contaminants and key cellular organelles like the mitochondria and lysosomes leads to a collapse in autophagic flux, preventing the clearance of misfolded proteins and thereby accelerating the progression of Parkinsonian-like neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics form disease-specific protein coronas, such as lysozyme-enriched coronas, which modulate immune signaling and contribute to systemic pathology.\n*   Alpha-synuclein structural folding is polymer-specific; polystyrene nanoplastics induce partial aggregation, while other plastic types may show different protein-binding affinities.\n*   The gut-brain axis is a primary site of initial MNP-induced pathology, where microbial dysbiosis acts as a precursor to systemic neuroinflammation.\n*   GSDMD-N, typically associated with pyroptosis, can translocate to mitochondrial membranes to amplify reactive oxygen species and facilitate lysosomal rupture.\n*   Small-molecule chaperones, such as ginsenoside Rg1 or specific natural extracts, have shown potential in restoring lysosomal acidification and clearing alpha-synuclein.\n*   The physical field disturbance coupled with advanced oxidation processes offers a mechanism-based strategy for cleaning BPA/NP-polluted water sources.\n*   Ferritinophagy, driven by lysosomal membrane disruption, results in iron accumulation, which further catalyzes oxidative injury and ferroptosis in dopaminergic systems.\n*   Lysosomal membrane stability serves as a conserved biomarker for microplastic-induced stress across diverse phylogenetic lineages, from marine invertebrates to mammalian tissues.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation."

Across primary mouse cortical neurons, MT-3 deficient primary mouse astrocytes, human iPSC-derived midbrain dopaminergic neurons, and Rho0 CHO cells lacking mitochondrial respiration, we investigated how mitochondrial stress perturbs zinc (Zn2+) homeostasis and lysosomal integrity. We identify intracellular zinc as a critical mediator linking mitochondrial dysfunction to lysosomal membrane permeabilization (LMP) and neuronal death. Inhibition of mitochondrial complex I by 1-methyl-4-phenylpyridinium (MPP+) elevated reactive oxygen species (ROS) and intracellular zinc, jointly driving LMP. Blocking either ROS or zinc markedly attenuated lysosomal damage and cell death, demonstrating that both act upstream of LMP. To define zinc regulation, we examined metallothionein-3 (MT-3), a brain-enriched zinc-binding protein. MT-3-deficient astrocytes were more vulnerable to MPP+ and zinc overload (ZnCl2) but paradoxically resistant to hydrogen peroxide (H2O2), suggesting that MT-3 buffers cytosolic zinc during mitochondrial injury or extracellular zinc influx yet can release bound zinc under oxidative conditions. Using Rho0 cells, we show that MPP+ toxicity depends on mitochondrial ROS, as loss of mitochondrial function nearly abolished cell death. However, Rho0 cells were highly sensitive to ZnCl2 and H2O2 and exhibited markedly reduced lysosomal abundance, indicating limited capacity to sequester zinc and increased susceptibility to zinc-mediated injury. These findings support a coordinated system in which lysosomes and zinc-binding proteins maintain zinc homeostasis. When cytosolic zinc rises, its accumulation within lysosomes induces LMP and accelerates cell death. Collectively, our results identify intracellular zinc as an upstream trigger of lysosomal dysfunction and neurodegeneration. Zinc-mediated LMP provides a mechanistic link between mitochondrial injury, impaired autophagic flux, and \u03b1-synuclein pathology in PD. Enhancing zinc homeostasis and lysosomal resilience may offer promising therapeutic strategies."

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology. Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters."

However, the synergistic toxicity of Ps-MPs and PBDEs on female fertility and oocyte quality remains insufficiently characterized. In this study, we established a 28-day oral exposure model in female ICR mice to evaluate the effects of Ps-MPs, PBDE-47, and their co-exposure on ovarian function, oocyte meiotic competence, and reproductive outcomes. Both Ps-MPs and PBDE-47 alone reduced ovarian weight, decreased antral follicles, increased follicular atresia, and markedly lowered ovulation and litter size, whereas co-exposure produced the most severe impairments. At the oocyte level, exposure significantly reduced germinal vesicle breakdown and first polar body extrusion, increased abnormal spindle formation and erroneous kinetochore-microtubule attachments, and suppressed TPX2 expression and \u03b1-tubulin acetylation. Cortical F-actin polarization, spindle migration, and membrane localization of JUNO and ovastacin were also disrupted, indicating widespread defects in meiotic and membrane maturation. Mechanistically, Ps-MPs and PBDE-47 induced a decline in mitochondrial membrane potential, aberrant mitochondrial distribution, excessive lipid accumulation, and Ca\u00b2\u207a imbalance, accompanied by autophagosome accumulation, lysosomal dysfunction, elevated ROS, increased \u03b3-H2AX signals, and enhanced Annexin V labeling, ultimately triggering DNA damage and apoptosis. All alterations were most pronounced under co-exposure. Collectively, Ps-MPs and PBDE-47 synergistically impair female fertility by converging on mitochondrial dysfunction, autophagy-lysosome imbalance, and oxidative stress-mediated DNA damage, leading to substantial reductions in oocyte quality.

In this study, we established a human-relevant polystyrene nanoplastics (PS-NPs, 50\u202fmg\u202fkg-1) oral exposure model in C57BL/6 mice in vivo and a neuro-immune microglial-neuron co-culture system (HMC-3/SH-SY5Y cells) in vitro to dissect these mechanisms. We demonstrate that PS-NPs exposure triggers microglial M1 activation and drives neuronal senescence. Mechanistically, PS-NPs activate the protein phosphatase 2A (PP2A)-B56\u03b3 subunit, which selectively dephosphorylates the ribosome biogenesis regulator ErbB3-binding protein 1 (Ebp1) at Ser335. This post-translational modification reduces Ebp1 nucleolar localization, suppresses 47S pre-ribosomal RNA transcription, and induces nucleolar stress. Consequently, the p53/p21 pathway is engaged, promoting neuronal senescence. Pharmacological inhibition of PP2A with LB-100 restored ribosome biogenesis, prevented neuronal senescence, and rescued cognitive deficits and neurodegenerative phenotypes in PS-NP-exposed mice.

To address this gap, we developed a mouse model subjected to coexposure to heat stress (36 \u00b0C, 4\u202fh/day) and well-characterized polystyrene nanoplastics (PS-NPs, 60\u202fnm, 10\u202fmg/kg/day) for 30 consecutive days. Multidisciplinary approaches, including behavioral testing, histopathological analysis and molecular profiling, were employed to assess cognitive dysfunction and its underlying mechanisms. Compared with the single-exposure groups, coexposure induced pronounced cognitive deficits in mice, which were concomitant with hippocampal neurodegeneration, bloodbrain barrier (BBB) compromise, and exacerbated hippocampal oxidative stress. Transcriptomic profiling and subsequent validation revealed a novel role for oxidative stress-induced NLR family pyrin domain containing 6 (NLRP6) inflammasome activation in driving microglial pyroptosis, which exacerbates neuroinflammation through a feedforward loop. The administration of the antioxidant N-acetylcysteine (NAC) attenuated these pathological alterations by suppressing oxidative damage, thereby rescuing cognitive performance. This study elucidates a novel mechanism whereby heat stress and PS-NP coexposure synergistically disrupt neurological homeostasis via redox-sensitive inflammatory pathways, offering critical insights for the development of preventive strategies against combined environmental neurotoxicity."

Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes. This study provided novel mechanistic insights into MPs-induced hepatotoxicity, identifying GSDMD-N as a potential central hub coordinating multiple cell death modalities."

The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate.

Increasing evidence demonstrates that MNPs are not confined to peripheral tissues but can accumulate even in the human brain, raising concerns about their potential contribution to neurological disease. This structured review synthesizes global trends in plastic production, environmental MNP burden, and human exposure, together with emerging data on brain accumulation, entry pathways, neurotoxic mechanisms, and key translational challenges. We present evidence showing that MNPs may cross brain barriers via multiple routes, including the blood-brain barrier, blood-cerebrospinal fluid barrier, olfactory, and circumventricular pathways, particularly under conditions of barrier vulnerability. Experimental studies reveal that once in neural tissue, MNPs may disrupt synaptic function, mitochondrial homeostasis, autophagy, and redox balance, while activating neuroinflammatory and gut-brain axis-mediated pathways. These mechanisms intersect with disease-relevant processes implicated in multiple neurological disorders whose global prevalence and societal burden have sharply increased over recent decades, including stroke, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, mood disorders, and neurodevelopmental conditions. Despite growing mechanistic plausibility, translational and human epidemiological evidence remains limited by methodological heterogeneity, a lack of standardized detection methods, and the absence of longitudinal clinical data/studies.

Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons.

This study explored the potential of BPA and NP to drive neuronal injury and ferroptosis linked to oxidative stress, acting through the transient receptor potential melastatin 2 (TRPM2)-poly (ADP-ribose) polymerase-1 (PARP1) signaling axis. Forty-two adult male Wistar rats were allocated into seven groups (control, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] NP, and low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA\u2009+\u2009NP) and treated orally for 21\u2009days. We employed a combinatorial approach of biochemical assays and immunohistochemistry to evaluate oxidative stress markers, ferroptosis hallmarks (glutathione peroxidase 4 [GPX4], solute carrier family 7 member 11 [SLC7A11], and transferrin receptor [TfRC]), apoptotic mediators (Caspase-3 and Caspase-9), and inflammatory cytokines, as well as the expression of TRPM2 and PARP-1. Results demonstrated that BPA and NP exposure triggered a robust, dose-dependent accumulation of reactive oxygen species (ROS) and lipid peroxidation, concomitant with downregulation of anti-ferroptotic proteins (GPX4 and SLC7A11) and upregulation of TfRC. This toxic insult simultaneously activated apoptotic and inflammatory cascades. Crucially, TRPM2 and PARP-1 were significantly upregulated, implying a potential role for the TRPM2-PARP-1 axis as an upstream modulator of oxidative stress-induced ferroptosis and neuroinflammation. Collectively, these findings provide novel mechanistic insights into phenol-induced neurotoxicity, highlighting the inhibition of the TRPM2-PARP-1 axis as a promising therapeutic strategy to mitigate environmental neurodegeneration in sensory neurons."

While diverse toxic effects of BHPF have been documented in the literature, its effects on neurons, potential neurotoxicity, and underlying molecular mechanisms remain unclear. In this study, we reported that BHPF (10, 25\u202f\u00b5M) inhibited neuronal SH-SY5Y cell viability, increased lactate dehydrogenase (LDH) release, and induced cell death in a dose-dependent manner. BHPF exposure increased intracellular reactive oxygen species (ROS) and mitochondrial reactive oxygen species (mtROS) levels, decreased mitochondrial membrane potential, reduced the expression of cytochrome C oxidase subunit 4 (COX4) and mitochondrial protein 1 (MFN1), but upregulated Bax, Caspase-3, Caspase-8 and initiated apoptosis. In addition, BHPF treatment led to the accumulation of acidic vacuoles in the cells and increased the expression of autophagy regulatory proteins, including Beclin-1, LC3II, ATG5 and p62. Moreover, BHPF could trigger endoplasmic reticulum stress (ER stress), and ER stress inhibitor taurodeoxycholate (TUDCA) reversed the BHPF-induced oxidative stress, apoptosis and autophagy. Thus, our in vitro data indicate that ER stress may be linked to the oxidative stress, apoptosis, and autophagy observed in nerve cells following BHPF exposure. These findings offer preliminary insights into cellular processes that could help elucidate the potential role of nerve cells in BHPF-associated degenerative diseases."

Surface-charged nPS variants (cationic, anionic, and neutral) show distinct biodistribution patterns, yet the mechanisms underlying their systemic damage remain incompletely understood. This study aimed to investigate the systemic injury mechanisms of nPS with different surface charges. Mice were exposed to fluorescently labeled cationic (amino-modified), anionic (carboxyl-modified), and neutral nPS via drinking water (25\u00a0mg/mL) for 3\u00a0weeks. Tissue distribution was analyzed using fluorescence microscopy; pathological changes were assessed via hematoxylin-eosin (HE) staining; metabolic perturbations were detected by metabolomic profiling. Mechanistic investigations were performed using metabolomics, flow cytometry, and molecular assays in AML12 hepatocytes and vascular endothelial cells. Fluorescence microscopy showed neutral nPS accumulated in the vascular endothelium of the stomach, intestine, and lung via passive diffusion, while cationic/anionic nPS penetrated hepatic sinusoids through charge-mediated interactions. HE staining revealed severe liver injury, with no significant abnormalities in other tissues. Metabolomic profiling indicated disrupted hepatic amino acid and lipid metabolism, depleted antioxidants (e.g., vitamin E and glutathione), and induced oxidative stress (evidenced by elevated hydroxy fatty acids). In hepatocytes, nPS-induced endoplasmic reticulum (ER) stress triggered excessive reactive oxygen species (ROS) production, inhibiting SLC7A11-mediated cystine uptake and glutathione synthesis, leading to disulfide stress (\u03b2-actin disulfide mispairing) and ferroptosis (GPX4 inactivation and iron accumulation). In contrast, neutral nPS induced endothelial cell senescence via phagolysosome dysfunction, causing lysosomal membrane permeabilization and \u03b2-galactosidase release. This study identifies a \"charge-specific injury\" paradigm: charged nPS induce hepatocyte ferroptosis via an ER stress-disulfide stress cascade, while neutral nPS trigger endothelial senescence through phagocytic dysfunction. These findings provide critical insights for the biosafety assessment of nanoplastics and identify potential targets for preventing plastic pollution-related liver diseases."

Shared pathophysiological pathways for Alzheimer's and Parkinson's disease.\nAbstract: The widespread presence of microplastics (MPs) in the environment has raised significant concerns about their potential impact on human health. As of 2023, the Ocean Conservancy estimates that adults may ingest up to 121,000 MPs annually. While the majority of these particles are cleared from the body, a small fraction can persist, as MPs are non-biodegradable and resist breakdown, posing long-term health risks that remain poorly understood. This review explores the emerging link between MP exposure and the development of neurodegenerative diseases, particularly Alzheimer's disease (AD) and Parkinson's disease [1]. MPs appear capable of triggering neurotoxic pathways, including activation of resident immune cells in the brain, oxidative stress, blood-brain barrier (BBB) disruption, mitochondrial dysfunction, and neuronal damage, which may contribute to neuroinflammation and disease progression. Specifically, six MP-related mechanistic pathways associated with AD were identified: BBB disruption, chronic inflammation, oxidative stress and ROS generation, mitochondrial dysfunction, impaired autophagy and proteostasis, and epigenetic alterations. Similarly, six pathways were implicated in PD: BBB disruption, oxidative stress in dopaminergic neurons, mitochondrial dysfunction, microglial-driven neuroinflammation, \u03b1-synuclein aggregation, and gut-brain axis [2] disruption. Ultimately, our findings underscore the urgent need for further research into the neurological consequences of chronic MP exposure in humans and highlight the importance of strengthening global policies to curb plastic pollution and mitigate its long-term health risks."

This review examines the molecular mechanisms by which lead, cadmium, mercury, arsenic, bisphenol A, phthalates, and dioxins modulate NLRP3 signaling. Lead and cadmium activate NLRP3 through mitochondrial dysfunction and oxidative stress, whereas mercury and arsenic suppress inflammasome assembly by preventing apoptosis-associated speck-like protein containing a CARD (ASC) oligomerization. EDCs engage receptor-mediated pathways: aryl hydrocarbon receptor (AhR) activation directly represses NLRP3 transcription, yet bisphenol A and phthalates override this suppression through NF-\u03baB activation. Developmental timing critically determines outcomes such as prenatal exposures epigenetically programing persistent NLRP3 dysregulation. Sex hormones have been shown to modulate distinct inflammatory landscapes: estrogen suppresses NLRP3 via ER\u03b2-dependent mechanisms, while testosterone amplifies inflammasome-dependent pathology. The skin serves as a primary interface for environmental chemical exposure and cutaneous NLRP3 activation. NLRP3-deficient mice exhibit 34% increased lifespan, and pharmacological inhibition with MCC950 extends lifespan in progeria models. The CANTOS trial demonstrated that targeting inflammation through IL-1\u03b2 neutralization confers cardiovascular benefits in high-risk humans. These findings position NLRP3 as a central integrator through which the chemical exposome accelerates inflammaging and identify inflammasome inhibition as a therapeutic strategy for environmental disease prevention."

Evidence indicates that these pollutants disrupt the autophagy-lysosome pathway, induce lysosomal membrane permeabilization (LMP), and trigger oxidative stress, which collectively converge on the pathological accumulation of alpha-synuclein.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nEnvironmental pollutants, specifically micro/nanoplastics and bisphenols, modulate the pathogenesis of Parkinson's Disease. Through the disruption of lysosomal acidification and the subsequent induction of lysosomal membrane permeabilization (LMP), these agents impair the autophagic-lysosomal pathway's ability to clear alpha-synuclein, thereby accelerating disease-associated neurodegeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe neurodegenerative trajectory of Parkinson's Disease is increasingly understood as a convergence of genetic vulnerability and environmental insult. The provided literature delineates a clear mechanistic bridge between environmental plastic/phenolic pollutants and PD pathology. Microplastics and nanoplastics penetrate the central nervous system, where they actively interfere with the lysosome's structural and functional capacity. Lysosomal membrane permeabilization, often triggered by zinc-mediated stress or direct surface binding, prevents the orderly degradation of alpha-synuclein, the hallmark protein of Lewy bodies. Similarly, bisphenol compounds initiate oxidative and endoplasmic reticulum stress, which suppresses lysosomal autophagy and exacerbates the aggregation of misfolded proteins.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics can cross the blood-brain barrier via multiple routes, including olfactory and circumventricular pathways, particularly when barrier integrity is compromised.\n*   The initiation of alpha-synuclein aggregation predominantly occurs at the lysosomal membrane surface.\n*   Zinc homeostasis serves as a vital regulatory nexus where mitochondrial dysfunction links to lysosomal failure via intracellular zinc accumulation.\n*   Polystyrene nanoplastics have been observed to trigger microglial M1 activation, which propagates neuroinflammation through a feedforward loop.\n*   There exists a \"charge-specific injury\" paradigm where surface properties of nanoplastics determine whether they trigger hepatocyte ferroptosis or endothelial senescence.\n*   Taurine depletion is a predictive biomarker for microplastic-induced cognitive decline and synaptic loss.\n*   GCase enzyme activity is a genetic convergence point for lysosomal degradation failure in both GBA1-mutant and environmentally stressed PD models.\n*   A \"kidney-brain axis\" in PD pathogenesis suggests that peripheral alpha-synuclein aggregates in renal tissues may precede systemic spread to the central nervous system.\n*   Small EPs or \"SECmeres\" (sub-50nm particles) in blood are emerging as potentially superior biomarkers compared to classical extracellular vesicles for brain-specific signatures.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42390437\nTitle: A Brain-Targeted DNA Delivery Nanocarrier Modulator for Synergistic Therapy of Parkinson's Disease.\nAbstract: The pathological characteristics of Parkinson's Disease (PD) are multifactorial, encompassing the aggregation of \u03b1-synuclein, mitochondrial dysfunction, and oxidative stress, necessitating the adoption of multitarget therapeutic strategies. In this study, a borneol-modified carboxymethyl chitosan nanoparticle system (BC/P/HCR NPs) was developed, aiming to codeliver curcumin, rosmarinic acid, and plasmid DNA (pDNA) targeting the SNCA gene for synergistic therapeutic intervention in PD. Borneol is capable of enhancing the permeability of the blood-brain barrier (BBB), while carboxymethyl chitosan contributes to improving the solubility of curcumin and preventing premature drug release. In a C57BL/6 mouse model of PD, BC/P/HCR NPs demonstrated enhanced penetration through the BBB, effectively alleviating motor dysfunction and reducing neuronal damage by downregulating the expression of \u03b1-synuclein, restoring mitochondrial function, and mitigating oxidative stress. These findings underscore the potential of BC/P/HCR NPs as a multifunctional nanotherapeutic platform for addressing the complex pathological features of PD.\n\nID: 42374481\nTitle: Hereditary spastic paraplegia (HSP) gene 11 (Spg11) attenuates lipid accumulation in myeloid cells and neuroinflammation in the midbrain without affecting \u03b1-synuclein pathology.\nAbstract: Hereditary spastic paraplegia type 11 (SPG11-HSP) is a neurodegenerative disorder caused by mutations in SPG11, which encodes the large scaffolding protein spatacsin, involved in lysosomal and autophagosomal trafficking. A portion of patients with SPG11 mutations present with parkinsonism features. While spatacsin dysfunction is linked to neurodegeneration, the underlying cellular mechanisms, especially in the midbrain, remain largely unclear. Here, we demonstrate that loss of Spg11 in mice results in neuroinflammation and lipid accumulation in myeloid cells. Bulk RNA sequencing revealed a strong upregulation of microglial genes in the midbrain of Spg11 knockouts, supported by increased CD68 and CLEC7A expression and morphological changes consistent with microglial activation. Spg11 depletion in two in vivo models of synucleinopathy revealed no enhancement of phosphorylated \u03b1-synuclein-positive inclusions or dopaminergic neuron loss; however, the mice did exhibit Spg11-dependent microglial reactivity. Further in vitro studies using primary bone-derived macrophages revealed increased phagocytic capacity and neutral lipid accumulation under basal and stress conditions. These findings support a model where SPG11 is a critical regulator of microglial activation and myeloid lipid metabolism, contributing to neurodegeneration through pathways distinct from \u03b1-synuclein-mediated pathology.\n\nID: 42365211\nTitle: A new paradigm in Parkinson's disease: kidney-origin \u03b1-synuclein pathology driven by PKC signaling and aurothioglucose.\nAbstract: Protein Kinase C (PKC), a zinc-dependent signaling enzyme essential for cellular homeostasis, has recently emerged as a critical regulator of \u03b1-synuclein (\u03b1-Syn) dynamics beyond the central nervous system. Growing evidence suggests that PKC may contribute to \u03b1-Syn accumulation in kidney cells through multiple converging mechanisms, including direct phosphorylation of \u03b1-Syn, which promotes its aggregation, disruption of the autophagy-lysosome pathway leading to impaired protein clearance, and amplification of oxidative stress and inflammatory responses that enhance \u03b1-Syn toxicity. In a paradigm-shifting discovery, recent findings from Wuhan University indicate that Parkinson's disease (PD) pathology may originate in peripheral organs such as the kidneys rather than the brain. Abnormal \u03b1-Syn aggregates have been identified in renal tissues of affected individuals, and experimental models demonstrate that compromised kidney function facilitates the systemic spread of these toxic proteins to the brain, potentially initiating neurodegeneration. Notably, \u03b1-Syn accumulation has also been observed in patients with chronic kidney disease in the absence of neurological symptoms, suggesting a potential early reservoir function of the kidneys. In this context, aurothioglucose (ATG), a gold-based anti-inflammatory agent, emerges as a promising therapeutic candidate due to its ability to modulate PKC signaling, attenuate inflammation, and restore proteostatic balance. This review highlights a novel kidney-brain axis in PD pathogenesis and proposes PKC-targeted interventions, including ATG, as potential strategies for early disease modification.\n\nID: 42335514\nTitle: Bacoside-A from Bacopa monnieri (L.) Wettst. in Parkinson's disease: In Silico and preclinical insights into dopaminergic neuroprotection.\nAbstract: Parkinson's disease (PD) presents a formidable therapeutic challenge rooted not in a singular pathogenic event but in the convergent failure of mitochondrial homeostasis, redox balance, \u03b1-synuclein proteostasis, autophagy-lysosomal integrity, and neuroinflammatory amplification within substantia nigra dopaminergic neurons. Existing dopaminergic pharmacotherapies address symptomatic deficits while leaving the underlying neurodegenerative cascade unchecked, underscoring the need for disease-modifying strategies with multi-target mechanistic reach. This review examines bacoside-A, the principal triterpenoid saponin complex of Bacopa monnieri (L.) Wettst., as a structurally distinctive, polypharmacological neuroprotective scaffold whose biological relevance emerges from convergence with core vulnerability pathways driving dopaminergic degeneration. Integrating in silico, in vitro, and in vivo evidence, we examine how bacoside-A engages molecular targets including \u03b1-synuclein aggregation intermediates, monoamine oxidase-B, LRRK2 kinase, PINK1-Parkin mitophagy regulators, and the redox sensor DJ-1, with computational predictions providing a coherent mechanistic framework for findings observed across MPP\u207a-, rotenone-, and 6-OHDA-based preclinical models, including attenuation of mitochondrial dysfunction, oxidative amplification, and apoptotic signalling, and partial nigrostriatal preservation with motor improvement in vivo. This review reframes bacoside-A as a stress-buffering, network-active modulator most relevant during early, pre-degenerative disease stages. While no clinical trial has yet evaluated bacoside-A in PD, and findings from cognitive or other non-PD indications cannot be extrapolated as efficacy evidence, the convergent mechanistic, computational, and preclinical evidence presented here provides a strong rationale for advancing bacoside-A toward systems pharmacology-guided preclinical and clinical evaluation as an adjunct neuroprotective candidate.\n\nID: 42335225\nTitle: Intracellular delivery of full-length antibodies via organ-targeted lipid nanoparticles.\nAbstract: Antibodies are proteins prized for their ability to bind to extracellular antigens with exceptionally high affinities and specificities. These features have motivated researchers to utilize antibody-antigen binding to inhibit intracellular disease targets in the proteome, yet delivery of antibodies into the cytosol of cells has long been a considerable challenge. Here, we outline the development of a lipid nanoparticle (LNP) platform for delivering antibodies into cells to selectively inhibit disease-relevant cytosolic targets. This approach efficiently delivers various therapeutic antibodies into multiple cancer cell lines, inhibiting key transcription factors in inflammatory and cancer signaling pathways. We further demonstrate systemic delivery of therapeutic antibodies in disease models, including \u03b1-synuclein-specific antibodies for Parkinson's disease and RelA-specific Immunoglobulins for acute lung injury using targeted LNP formulations. This work establishes a promising method for using LNPs for the delivery of antibody and antibody-derived therapeutics intracellularly to treat numerous proteome targets.\n\nID: 42331820\nTitle: SECmeres outperform extracellular vesicles as potential blood RNA biomarkers for Alzheimer's disease.\nAbstract: Cells release heterogeneous extracellular vesicles and particles (EVPs) into circulation, carrying RNA and proteins that reflect their origin. Recently, brain-derived EVs have gained significant attention as non-invasive biomarkers for Alzheimer's disease (AD). Here, we identified sub-50nm extracellular nanoparticles in human brain and blood that lack the hallmarks of small EVs, exosomes, exomeres, and supermeres but are enriched for brain-specific markers, hereafter termed small EPs or 'SECmeres'. We discovered that RNAs associated with SECmeres discriminated AD cases from controls with higher significance than small EVs, large EVs showed no differences. Discriminating RNAs were enriched in small EVs (Synaptotagmin, Alpha-synuclein, MAPT) or SECmeres (L1CAM, Syntaxin, Neurogranin), indicating distinct brain-derived signatures. Single-cell RNAseq deconvolution shows small EVs contain RNAs from diverse brain cells, whereas SECmeres enrich brain endothelial transcripts, lining cerebral blood vessels and forming the blood-brain barrier (BBB). These findings challenge the prevailing view that small EVs are the primary carriers of biomarkers. Collectively, our study shows that blood EVPs carry brain-specific information for liquid biopsy, pending validation in larger blinded clinical trials.\n\nID: 42262134\nTitle: Alpha-synuclein at the crossroads of host-virus interactions: immunological roles beyond the nervous system.\nAbstract: Alpha-synuclein (\u03b1-syn) is best known as a presynaptic protein that supports synaptic vesicle dynamics and neurotransmission. Conversely, misfolded or aggregated \u03b1-syn represents a hallmark of synucleinopathies, including Parkinson's disease. Beyond the nervous system, \u03b1-syn has been detected in peripheral compartments, including blood cells and selected epithelial tissues, although the robustness and context dependence of expression outside neuronal and erythroid lineages remain under active investigation. Also, it can be released extracellularly through unconventional secretion or cell damage. These observations have reframed \u03b1-syn as an immune-relevant molecule positioned at host-pathogen interfaces, endowed with antimicrobial peptide-like and damage-associated molecular pattern-like properties that enable shaping of both innate and adaptive immunity. Increasing evidence indicates that viral challenge alters \u03b1-syn expression, localization, and conformational states in central and peripheral settings, in part through interferon-dependent programs that couple antiviral immunity with cellular homeostasis. A plethora of RNA viruses, such as influenza virus, flavivirus, enterovirus, and coronavirus, perturb \u03b1-syn abundance, post-translational modifications, trafficking, secretion, and aggregation propensity. These effects converge on shared mechanisms that include altered proteostasis, autophagy-lysosomal dysfunction, oxidative and mitochondrial injury, and inflammatory signaling. Importantly, outcomes are highly context dependent, ranging from cell-intrinsic antiviral restriction to aggregation-prone states that may fuel chronic inflammation and neurodegeneration. Collectively, the evidence discussed herein supports a dual framework in which \u03b1-syn contributes to antiviral defense; yet, under conditions of sustained inflammation or impaired clearance, it may undergo pathological transformation that promotes neuronal damage. Defining when virus-induced \u03b1-syn responses are protective versus pathogenic, and clarifying their relevance to human disease, will be critical for developing strategies that target host-virus interactions, neuroinflammation, and \u03b1-syn proteostasis in infection-associated synucleinopathies.\n\nID: 42261162\nTitle: Targeting \u03b1-Synuclein Aggregation in Parkinson's Disease: A Narrative Review of Current Gene Therapy Strategies.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the accumulation of misfolded \u03b1-synuclein (\u03b1-syn) aggregates, leading to dopaminergic neuronal loss and motor dysfunction. Current pharmacological treatments primarily provide symptomatic relief and have a limited impact on disease progression. This article presents a narrative review of emerging gene therapy approaches aimed at modulating \u03b1-syn expression, aggregation, and clearance as potential disease-modifying strategies for PD. Gene-based interventions include viral vector-mediated gene delivery, antisense oligonucleotides, RNA interference, and gene-editing technologies. Preclinical studies and early-phase clinical trials suggest that these approaches may reduce \u03b1-syn burden, improve motor outcomes, and support dopaminergic neuron preservation. Adeno-associated viral and lentiviral vectors have demonstrated promise for targeted central nervous system delivery, although challenges related to dosage optimization, regional specificity, long-term safety, and immune responses remain. Complementary strategies focusing on enhancing molecular chaperone activity and activating autophagy-lysosomal pathways have also shown potential in facilitating \u03b1-syn clearance. Despite encouraging progress, several limitations hinder clinical translation, including off-target effects, immune activation, and the need to preserve physiological \u03b1-syn functions essential for neuronal homeostasis. Future success will depend on precise molecular targeting, optimized delivery platforms, and rigorous safety evaluation through well-designed clinical trials. This narrative review summarizes current advances, key limitations, and future directions in \u03b1-syn-targeted gene therapy, highlighting its potential role in advancing PD treatment beyond symptomatic management toward disease modification.\n\nID: 42234812\nTitle: Exosome mimetic nanoparticles for siRNA based targeting of \u03b1-synuclein and neuroinflammation in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disorder caused by degeneration of dopaminergic neurons and accumulation of \u03b1-synuclein protein, leading to sustained neuroinflammation. This review analyze the application of gene silencing mediated by small interfering RNAs for \u03b1-synuclein protein and inflammatory factors in the treatment of PD. The use of exosomes-mimetic nanoparticles (EM-NPs) for siRNA delivery will be highlighted in particular. This review highlights recent findings on the molecular mechanisms involved in PD, the development of siRNA drugs, and the potential of EM-NP-mediated siRNA delivery systems for CNS delivery. siRNA provides an excellent approach to silence specific disease-related genes, such as SNCA and inflammatory factors. Nevertheless, its practical application is hampered by low stability, enzymatic degradation, difficulty crossing the BBB, and non-specific activity. EM-NPs combine the advantages of biocompatibility and scalability that natural exosomes possess and synthetic nanoparticles exhibit, respectively. The delivery of siRNA molecules via EM-NPs could be considered an innovative disease-modifying approach toward treating PD patients, involving both pathological \u03b1-synuclein protein and neuroinflammation.\n\nID: 42231093\nTitle: Nrf2/NOX2 Pathway Dysregulation and Oxidative Stress Biomarkers in Gaucher Disease-Associated Parkinsonism: Insights Into a Potential Therapeutic Target.\nAbstract: Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder, yet its underlying genetic and molecular mechanisms remain incompletely understood. Variants in the GBA gene, encoding the lysosomal enzyme glucocerebrosidase, are not only responsible for Gaucher disease (GD) but also represent a significant genetic risk factor for PD, contributing to lysosomal dysfunction, oxidative stress and autophagy impairment. Among the key regulators of redox homeostasis, the Nrf2/NOX2 signalling axis has emerged as a pivotal pathway in the modulation of neuroinflammation and neurodegeneration. This study aims to explore the pathogenic link between GBA mutations and PD, focusing on the redox imbalance and the role of Nrf2 signalling in an in\u00a0vivo Gba D409V knock-in (KI) mouse model, compared to wild-type (WT) C57BL/6J controls. Animals 8-weeks old were evaluated over a 3-month period, with tissue and behavioural assessments conducted at 7, 14, 30, 60 and 90\u2009days. Early timepoints (7 and 14\u2009days) did not reveal significant changes in behavioural performance, expression of PD-related markers (TH, DAT, \u03b1-synuclein), or oxidative stress indicators, including Nrf2, NOX2, malondialdehyde (MDA) and nitrate/nitrite levels. However, at 30, 60 and especially 90\u2009days, significant alterations emerged, particularly a disrupted Nrf2/NOX2 balance, accompanied by molecular and biochemical signatures of oxidative stress. These findings suggest a time-dependent progression of oxidative alterations in this GD model and support the role of GBA variants in promoting neurodegenerative processes. Unravelling these mechanisms is essential for the identification of early biomarkers and may offer new therapeutic insights for GBA1-associated PD.\n\nID: 42201050\nTitle: Urinary Biomarkers in Parkinson's Disease: A Structured Integrative Review of Pathophysiological Pathways.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by complex and interconnected pathophysiological mechanisms, including mitochondrial dysfunction, oxidative stress, neuroinflammation, lysosomal impairment, and altered neurotransmitter metabolism. Unlike cerebrospinal fluid or blood, urine offers a truly non-invasive source of biomarkers, reflecting systemic metabolic changes and renal protein excretion linked to neurodegeneration. This review aims to critically synthesize current evidence on urinary biomarkers in PD and to organize this heterogeneous literature into pathophysiologically meaningful domains. A comprehensive literature search of human studies investigating urinary biomarkers in PD was performed. Eligible studies were comprehensively analyzed and classified according to dominant biological pathways. To facilitate interpretation, findings were organized into six thematic domains: genetic and protein-based biomarkers; metabolic pathways and mitochondrial dysfunction; oxidative stress and neuroinflammation; gut-brain-axis-related metabolites; hormonal and systemic biomarkers; and emerging exploratory markers. Results were summarized in domain-specific tables and integrated using a conceptual framework. A total of 32 human studies met the inclusion criteria, revealing diverse urinary molecular signatures associated with PD across multiple biological domains. Genetic and protein-based markers, including LRRK2-related proteins, \u03b1-synuclein species, and lysosomal lipids, showed potential for disease stratification. Metabolomic studies consistently identified alterations in acylcarnitines, organic acids, and amino acid metabolism, reflecting mitochondrial dysfunction. Biomarkers related to oxidative stress, immune activation, gut microbiota metabolism, and hormonal regulation further highlighted the systemic nature of PD. However, most individual biomarkers lacked disease specificity and exhibited methodological heterogeneity. Current evidence supports urine as a valuable source of systemic biomarkers reflecting multiple pathophysiological processes in PD. While single urinary markers remain insufficient for clinical application, integrated omics-based approaches-particularly metabolomics and peptidomics/proteomics-hold promise for identifying combinatorial biomarker signatures. Future longitudinal and standardized studies are required to enhance specificity and translational potential for non-invasive diagnosis and disease monitoring in PD.\n\nID: 42191076\nTitle: Long-term low-dose nanoplastic exposure induces neurotoxicity with oxidative brain damage.\nAbstract: The potential health impacts of nanoplastic exposure have attracted significant scientific interest, with emerging evidence linking their presence to various human diseases. Alarmingly, polystyrene nanoplastics (PS-NPs) have been detected in brain tissues, showing their capability to penetrate the blood-brain barrier (BBB). However, most previous animal studies used high-dose acute exposures, which may not properly reflect the common long-term, low-dose exposure scenarios in real-world. Thus, we conducted a 17-month exposure study in mice using PS-NPs with significantly lower dosage and assessed their behavior and brain damage. Our results demonstrated that prolonged exposure induced oxidative stress in the brain with significantly elevated reactive oxygen species (ROS) and malondialdehyde (MDA) levels, as well as activated immune responses, including microglial activation (Iba1+) and increased release of inflammatory cytokines, indicating a chronic inflammatory state in the brain. In behavioral experiments, only the elevated plus maze (EPM) showed significant differences, however, pathways linked to neurodegenerative diseases like Parkinson disease were notably upregulated. This unfavorable molecular network restructuring may heighten the risk for such disorders. These findings provide critical evidence for the adverse neural effects of long-term, low-dose PS-NPs exposure, thus laying the ground for further more detailed investigation and offering insights for future health interventions and preventive strategies.\n\nID: 42183628\nTitle: CHCHD2 and CHCHD10 promoted autophagic clearance of protein aggregates via GABARAPs.\nAbstract: Mutations in mitochondrial protein CHCHD2 and its paralog CHCHD10 were identified in patients with Parkinson disease (PD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) or Alzheimer disease (AD). CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons. Importantly, CHCHD2 and CHCHD10 promoted autophagy. CHCHD2 reduced protein aggregates in cells and toxic SNCA/\u03b1-synuclein species in mouse striatum. Our study thus revealed mitochondrial proteins CHCHD2 and CHCHD10 as both autophagy substrates and autophagy activators and laid groundwork for therapy targeting patients with neurodegeneration.Abbreviations: AA: amino acid; AD: Alzheimer disease; ALS: amyotrophic lateral sclerosis; ATG5: autophagy related 5; ATG7: autophagy related 7; ATG8: mammalian Atg8-family protein; ATG13: autophagy related 13; bafA1: bafilomycin A1; C1QBP/p32/gC1qR/HABP1: complement component 1, q subcomponent binding protein; CHCHD2/MNRR1/MIX17B: coiled-coil-helix-coiled-coil-helix domain containing 2; CHCHD10/MIX17A: coiled-coil-helix-coiled-coil-helix domain containing 10; CHX: cycloheximide; CMA: chaperone-mediated autophagy; CRISPR: clustered regularly interspaced short palindromic repeats; CQ, chloroquine; DA: dopaminergic; DMSO: dimethyl sulfoxide; EBSS: Earle's balanced salt solution; RB1CC1/FIP200: RB1 inducible coiled-coil 1; FTD: frontotemporal dementia; GABARAP: gamma-aminobutyric acid receptorbassociated protein; GABARAPL1: GABA type A receptor associated protein like 1; GABARAPL2: GABA type A receptor associated protein like 2; hESC: human embryonic stem cells; iPSC: induced pluripotent stem cell; KO: knockout; LAMP1: lysosomal-associated membrane protein 1; LAMP2A: lysosomal-associated membrane protein 2A; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; LIR: LC3-interacting region; PD: Parkinson disease; SQSTM1/p62: sequestosome 1; TARDBP/TDP-43: TAR DNA binding protein; TH: tyrosine hydroxylase; TMR, tetramethylrhodamine; WT: wild type; UB: ubiquitin; ULK1: unc-51 like kinase 1.\n\nID: 42159234\nTitle: Reactive Oxygen Species-Responsive Targeted Polydopamine-Rosmarinic Acid Nanotherapeutics for Ferroptosis-Driven Parkinson's Disease Modulation in Caenorhabditis elegans.\nAbstract: Parkinson's disease (PD), a progressive neuropathy marked by abnormal \u03b1-synuclein (\u03b1-Syn) deposition and oxidative stress-driven degeneration of dopaminergic neurons (DA neurons), remains inadequately addressed by current palliative strategies that primarily provide symptomatic relief, emphasizing the need for enhanced therapeutic modalities. In particular, ferroptosis, an iron cell death mechanism, is a key driver of PD pathogenesis, and its modulation represents a feasible therapeutic target. Here, we designed a neuromelanin-mimetic polydopamine (PDA)-based nanomedicine to attenuate ferroptosis-associated oxidative stress and iron dysregulation in PD by functionalizing PDA nanoparticles with triphenylphosphonium (TPP) for mitochondrial targeting and loading rosmarinic acid (RA), yielding TPRA nanoparticles (TPRA NPs). TPRA NPs combine the antioxidative and iron-chelating attributes of RA with reactive oxygen species (ROS)-responsive release properties. TPRA NPs exhibited efficient RA loading, sustained ROS-triggered release, effective iron chelation, and comprehensive free radical neutralization. In vivo evaluations in Caenorhabditis elegans demonstrated that TPRA NPs were well-tolerated at concentrations up to 64 \u03bcg/mL, with no detectable adverse effects, and enhanced healthspan and stress resistance. TPRA NPs markedly attenuated ferroptosis-associated markers by decreasing excess iron, lipid peroxidation, and ROS while simultaneously restoring glutathione balance, locomotor performance, and modulating ferroptosis-associated genes in worms induced with 1-methyl-4-phenylpyridinium (MPP+), erastin, or iron. Furthermore, these nanoparticles preserved the viability of DA neurons and restored neurobehavioral function and mitochondrial integrity. TPRA NPs reduced \u03b1-synuclein deposition, lengthened lifespan, and activated SKN-1 signaling while upregulating mitophagy-related genes in \u03b1-Syn expressing NL5901 worms, thereby strengthening endogenous defenses. These findings establish targeted, natural polyphenol-loaded biomimetic nanoparticles as a potential approach to mitigate ferroptosis-associated stress in PD.\n\nID: 42154395\nTitle: Plant-derived neuroprotective compounds and nanoformulations targeting Parkinson's disease: a semi-systematic review of mechanisms and therapeutic potential.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by aggregates of \u03b1-synuclein and the degeneration of dopaminergic neurons in the substantia nigra. Current pharmaceutical therapies mainly alleviate symptoms without halting disease progression. Evidence suggests that traditional plant-based interventions may serve as supplementary therapies by targeting oxidative stress, mitochondrial dysfunction, neuroinflammation, and apoptosis. This review explores the neuroprotective properties of ten medicinal plants commonly used in traditional medicine: Bacopa monnieri, Curcuma longa, Mimosa pudica, Zingiber officinale, Ocimum sanctum, Emblica officinalis, Camellia sinensis, Cannabis sativa, Panax ginseng, and Withania somnifera. A systematic and comprehensive search of PubMed, Scopus, and Web of Science identified relevant in vitro, in vivo, and clinical studies. This study highlights the mechanisms by which plant-derived chemicals influence cellular pathways associated with PD, emphasising their therapeutic potential despite limited clinical validation. Studies have shown that bioactive compounds such as curcumin, bacoside, Epigallocatechin-3-gallate (EGCG), cannabidiol, ginsenosides, and withanolides exhibit antioxidant, anti-inflammatory, anti-apoptotic, and neuroprotective effects in PD models. Nanotechnology offers promising strategy to enhance the efficacy of herbal compounds, addressing challenges of poor solubility, rapid metabolism, low bioavailability, and restricted blood-brain barrier penetration. Nano-delivery systems including liposomes, polymeric nanoparticles, nanoemulsions, and metal nanoparticles can improve stability, brain targeting, controlled release, and cellular uptake of these bioactives, thereby enhancing therapeutic efficiency while reducing systemic toxicity. Green-synthesized plant-based nanoparticles further provide synergistic neuroprotective benefits, positioning phyto-nanomedicine as a multi-target approach for PD therapy. However, extensive clinical studies are required to confirm safety and effectiveness.\n\nID: 42154074\nTitle: \u03b1-Synuclein as a molecular link between Parkinson's disease and chronic kidney disease: insights into the kidney-brain axis.\nAbstract: \u03b1-synuclein (\u03b1-syn), a presynaptic protein encoded by the SNCA gene, is implicated in the pathogenesis of Parkinson's disease (PD) because of its tendency to misfold and form aggregates. Emerging evidence suggests that \u03b1-syn dysfunction may also affect peripheral organs, with chronic kidney disease (CKD) increasingly recognized as a potential comorbidity. This review critically examines current evidence on the molecular pathways linking PD and CKD through \u03b1-syn. \u03b1-Syn comprises an N-terminal lipid-binding domain, a non-amyloid component (NAC) region prone to aggregation, and a C-terminal domain that regulates conformational stability. Among the proposed mechanisms, mitochondrial dysfunction, oxidative stress, and impaired autophagy-lysosomal clearance represent the most consistently reported pathways across neuronal and renal systems, while activation of the renin-angiotensin system (RAS) has been implicated in more limited or context-dependent studies. Preclinical and limited clinical observations indicate that \u03b1-syn-associated processes may contribute to podocyte injury and fibrotic remodeling in renal tissue, whereas reduced \u03b1-syn expression has been suggested to compromise epithelial cell stability. These findings support the concept of a kidney-brain axis; however, the extent and directionality of this interaction remain incompletely defined. Novel \u03b1-syn-targeted therapies, including ENT-01, Cu(II)ATSM, ambroxol, and lipid-modulating strategies, are being investigated for their cross-organ efficacy, although most evidence currently derives from preclinical or early-phase studies. Importantly, key knowledge gaps persist, including the mechanisms underlying peripheral \u03b1-syn aggregation, the pathways of inter-organ communication, and the clinical validity of \u03b1-syn-based biomarkers. Overall, current evidence supports a potential role for \u03b1-syn as a contributing molecular link between neurodegenerative and renal dysfunction, rather than a definitive unifying mechanism, underscoring the need for integrated and evidence-driven diagnostic and therapeutic approaches.\n\nID: 42152674\nTitle: Redefining Parkinson's Care: The Promise of Nanotechnology and Artificial Intelligence.\nAbstract: Parkinson's Disease (PD) is a progressive neurodegenerative disorder characterized by the depletion of dopaminergic neurons and the buildup of \u03b1-synuclein aggregates, resulting in damaging motor and non-motor symptoms. Conventional therapies, comprising levodopa and dopamine agonists, give symptomatic relief but fail to terminate disease progression and are associated with long-term complications. Relevant review papers and articles from the past were investigated. Certain factors, including early disease diagnosis, therapeutic efficacy in PD models, and predictive modeling of drug-nanoparticle interactions, were considered during the conduct of this research. This literature review is a comprehensive narrative of research articles obtained from various platforms, namely Scopus, PubMed, Google Scholar, and Research Gate. Inclusion and exclusion criteria were applied to filter out the suitable materials. Artificial intelligence (AI) is emerging as a complementary tool, facilitating design-optimized nanocarriers and predicting drug interactions while emphasizing liposomes and metallic nanoparticles as important platforms for dopamine replacement, gene therapy, and neuroinflammation modulation. Despite the progress made so far, clinical translation still has considerable challenges to overcome, including nanoparticle toxicity, scalability, long-term safety, and variability in AI model performance. Integration of AI with biologically relevant PK/PD models and personalized nanomedicine strategies should overcome such existing gaps and enhance the therapeutic reliability of nanomedicine. This review summarizes current advances in nanomedicine and AI-driven approaches for PD, discussing their mechanisms, therapeutic targets, and future perspectives in achieving disease-modifying interventions.\n\nID: 42121002\nTitle: Knockout of Rab27b exacerbates neuropathology in alpha-synuclein mouse models.\nAbstract: Parkinson's Disease (PD) and other synucleinopathies are characterized by the formation of inclusions comprised of alpha-synuclein (\u03b1syn) among other proteins, but the mechanisms by which these inclusions form and cause toxicity are not well understood. We have previously reported that the small GTPase Rab27b modulates autophagic-lysosomal function in neurons and supports lysosomal degradation of \u03b1syn across multiple \u03b1syn cellular models. Knockout (KO) and knockdown (KD) of Rab27b damage lysosomal degradative capacity and exacerbate \u03b1syn pathology, while Rab27b overexpression is conversely protective in cellular \u03b1syn models. Elevations of Rab27b seen in human synucleinopathies suggest a compensatory role for Rab27b in these disorders. Here, we examined the role Rab27b plays in vivo in the context of both A53T genetic \u03b1syn overexpression and viral AAV \u03b1syn overexpression mouse models. Rab27b knockout in A53T+ mice did not alter motor behavior or survival. However, Rab27b knockout increased proteinase-K resistant \u03b1syn in the cortex, striatum, and substantia nigra of A53T mice starting as early as six months of age. Additionally, Rab27b KO increased phosphorylated S129 \u03b1syn in the cortex and nigra. Astrocyte and microglial activation were also observed upon Rab27b KO in the A53T model. In the AAV \u03b1syn model, Rab27b KO resulted in dopaminergic cell loss in the nigra, which was not observed in WT mice. Collectively, we report that loss of Rab27b results in elevated neuropathology in PD-relevant brain regions, validating its role as a therapeutic target in synucleinopathies.\n\nID: 42114425\nTitle: Life-cycle exposure to tris(2-butoxyethyl) phosphate at environmentally relevant concentrations induces progressive Parkinsonian-like neurodegeneration via lysosomal dysfunction in Caenorhabditis elegans.\nAbstract: Environmental contaminants are increasingly recognized as key risk factors for chronic diseases, including neurodegenerative disorders. Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology. Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters.\n\nID: 42105291\nTitle: Targeting the NLRP3 inflammasome with antibody-based therapeutics for chronic neurodegenerative diseases.\nAbstract: The NLRP3 inflammasome is a central regulator of innate immunity that becomes aberrantly activated by amyloid-\u03b2, hyperphosphorylated tau, and \u03b1-synuclein aggregates in chronic neurodegenerative diseases, such as Alzheimer's (AD) and Parkinson's disease (PD). Sustained activation drives neuroinflammation, synaptic dysfunction, and neuronal loss, making NLRP3 a compelling therapeutic target. This review summarizes current insights into NLRP3 inflammasome biology in AD and PD, with emphasis on antibody-based interventions. Emerging delivery approaches, such as receptor-mediated transcytosis, nanoparticles, adeno-associated viral vectors, and magnetic resonance-guided focused ultrasound are also examined for their potential to enhance central nervous system (CNS) delivery of NLRP3-targeting antibodies. Antibody-based NLRP3 inhibitors offer high specificity and favorable safety profile compared with small-molecular-weight inhibitors; however, limited blood-brain barrier (BBB) penetration remains a major challenge. Advances in antibody engineering, modular bi-/multi-specific designs, and targeted CNS delivery platforms may soon enable the development of first-in-class antibodies capable of directly modulating neuroinflammation. To realize this potential, the field should prioritize: (1) developing BBB-penetrant antibody constructs; (2) integrating delivery technologies with target biology; and (3) accelerating translation toward first-in-human studies. Successful implementation could transform therapeutic strategies for AD and PD and extend antibody-based interventions across a broader spectrum of neuroinflammatory disorders.\n\nID: 42103223\nTitle: The role of phospho-ubiquitin in mitochondrial health and diseases.\nAbstract: Mitochondria play a major role in cellular health, yet their contribution to chronic diseases has been underestimated. Mitochondria are essential for all tissues and are the major source of ATP in high-energy-demand organs such as brain and heart, which consequently are vulnerable to mitochondrial dysfunction. Failure to repair or remove damaged mitochondria contributes to aging and chronic diseases. Cells have evolved quality control mechanisms, including mitophagy to eliminate damaged mitochondria and mitobiogenesis to replenish them. The ubiquitin-proteasome system (UPS) is responsible for removing misfolded proteins, a process that is highly ATP dependent and therefore reliant on mitochondrial function. In turn, damaged mitochondria are eliminated through coordinated actions of the UPS and lysosomal degradation through mitophagy. Many neurodegenerative diseases are characterized by the presence of disease-specific protein aggregates, such as \u03b1-synuclein aggregates in Parkinson's disease and tau neurofibrillary tangles in Alzheimer's disease. These aggregates impair mitochondrial function, while dysfunctional mitochondria generate reactive oxygen species that further exacerbate proteotoxic stress, creating a pathogenic cycle. This highlights the functional interplay between mitochondria and the UPS. Recent studies have uncovered phosphorylation of ubiquitin at serine 65 by the mitochondrial kinase PINK1 as a key signal of mitochondrial dysfunction. Phospho-Ser65-ubiquitin (pUb) has emerged as an indicator of mitochondrial health and a potential biomarker for aging and neurodegenerative disease. However, due largely to a lack of tools, little is known about the role of pUb in cellular physiology. Here, we review the current landscape of pUb biology, the phospho-ubiquitome, and its role as biomarker for mitochondrial health and neurodegeneration.\n\nID: 42035925\nTitle: Galectins as stress-integrating regulators of neuroimmune signaling and proteinopathy in the central nervous system.\nAbstract: Galectins are \u03b2-galactoside-binding lectins that play increasingly mechanistic functions in central nervous system (CNS) physiology and disease. Over the past decade, a rapidly expanding literature has identified galectins as regulators of microglial activation, misfolded protein pathology, vesicle damage sensing, autophagy, synaptic plasticity, myelination, vascular repair, and neuroimmune communication. Galectins operate across intracellular and extracellular compartments to integrate cellular stress and innate immune signaling. Here, we review CNS studies of galectin-1, galectin-3, galectin-4, galectin-8, and galectin-9, focusing primarily on work published from 2019 onward while incorporating selected earlier studies to establish foundational concepts. Across experimental models and human studies, galectins orchestrate microglial state transitions, regulate aggregation and propagation of amyloid-\u03b2, tau, \u03b1-synuclein, and mutant huntingtin, and function as intracellular sensors of vesicle and lysosomal damage. Multiple studies further establish galectins as biomarkers and therapeutic targets across Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, retinal degeneration, and chronic pain. Importantly, this review highlights a stage- and context-dependent paradox in which the same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others. Together, these findings position galectins as central regulators that convert intracellular stress into coordinated neuroimmune programs shaping proteinopathy, circuit dysfunction, and tissue remodeling.\n\nID: 42033266\nTitle: Lysosome-Acidifying Nanoparticles Rescue A30P \u03b1-Synuclein Induced Neuronal Death in Cellular and Drosophila Models of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is the second most common neurodegenerative disorder, affecting over 10 million people worldwide. It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation.\n\nID: 42284733\nTitle: VPS13C-mediated endoplasmic reticulum-lysosome tethering in neuronal stress responses.\nAbstract: Organelle contact sites are increasingly recognized as regulatory interfaces that coordinate lipid transfer, ion signaling, and metabolic adaptation. In neurons, communication among the endoplasmic reticulum (ER), lysosomes, and mitochondria is essential for cellular homeostasis. Recent studies have identified vacuolar protein sorting 13 homolog C (VPS13C), a lipid transport protein, as a key mediator of ER-lysosome tethering and as an important component of the response to lysosomal stress. Structural analyses show that VPS13 family proteins form elongated lipid transport channels that are proposed to facilitate phospholipid transfer between adjacent membranes. Following lysosomal damage, VPS13C is recruited to ER-lysosome contact interfaces, where it forms tethering bridges that may support membrane repair by enabling high-capacity lipid transfer from the ER to lysosomal membranes. Beyond membrane repair, these contact interfaces may also participate in broader organelle communication networks. ER-lysosome contacts can occur in proximity to ER-mitochondria junctions, potentially forming multi organelle signaling hubs that coordinate lipid redistribution, calcium signaling, and mitochondrial adaptation. These signals may influence downstream responses, including activation of TFEB and TFE3, which regulate lysosomal biogenesis and autophagy. Disruption of this contact site network has emerged as a potential contributor to Parkinson's disease. Loss of VPS13C function is associated with altered lysosomal homeostasis and intersects with pathogenic pathways involving \u03b1-synuclein aggregation, PINK1/Parkin-mediated mitophagy, and LRRK2 signaling. This review presents a framework in which ER-lysosome tethering is considered part of a staged cellular damage response linking membrane repair, metabolic coordination, and transcriptional adaptation.\n\nID: 42276620\nTitle: Invisible threats of microplastics induced toxicity: Oxidative and inflammatory pathways in the CNS and retina.\nAbstract: The global spread of microplastics has become a serious public health concern. Once thought to be inert, microplastics are now recognized as biologically active agents capable of accumulating in the body and causing toxic effects across organ systems. This review summarizes current evidence on their oxidative and inflammatory effects in the central nervous system (CNS) and the eye. Studies show that microplastics can cross biological barriers such as the blood-brain barrier (BBB) and blood-retinal barrier (BRB), where they are taken up by cells, impair mitochondria, and trigger inflammation. Microplastics have been found in cerebrospinal fluid, brain tissue, and ocular structures, raising concern about their link to neurodegenerative and retinal diseases, including Alzheimer's, Parkinson's, macular degeneration, and other disorders. Mechanistic data indicate activation of NF-\u03baB and TGF-\u03b21 pathways, promotion of protein aggregation, and disruption of neural signaling. In the eye, microplastics have been linked to oxidative stress, corneal thinning, and photoreceptor damage. However, human studies are limited due to challenges in detecting tiny particles and lack of microplastic-free controls. Research is further hindered by inconsistent definitions, particle diversity, and non-physiological exposure models. We highlight the need for standardized methods, multi-omics tools, and long-term studies to better understand exposure impacts. Given the rise in neurological and ocular diseases, clarifying the role of microplastics is essential for effective public health strategies.\n\nID: 42172709\nTitle: Micro- and nanoplastics in the central nervous system: Transport pathways, neurotoxicity, and implications for brain disorders.\nAbstract: Micro- and nano-plastics (MNPs) are widely distributed across global ecosystems and have been extensively detected in human tissues, including the brain. The levels of MNPs are highly correlated with the occurrence of various brain disorders, suggesting the potential central nervous system (CNS) toxicity of MNPs. In this review, we summarize the major circuits by which MNPs may transport into and out of the CNS, including blood-brain barrier crossing, nasal-to-brain routes, and glymphatic system transport. Small-sized MNPs are difficult to eliminate from the brain, which may explain why MNPs may accumulate in the brain. We further discuss the potential neurotoxic effects of MNPs, such as inducing synaptic and neuronal injury, promoting neuroinflammation, dysregulating the neuroendocrine system, and modulating the gut-brain axis. MNP-induced CNS toxicity follows a pattern in which increased susceptibility occurs before direct toxicity. We also review evidence that MNPs, together with environmental and genetic factors, may synergistically contribute to cognitive impairment in Alzheimer's disease, motor dysfunction in Parkinson's disease, and depression- and anxiety-like behaviors. Prenatal exposure to MNPs might induce autism spectrum disorder-related phenotypes in offspring. MNPs could also obstruct cerebral vessels and trigger acute cerebrovascular diseases, as well as promote the entry of viruses such as SARS-CoV-2 into the CNS, thereby increasing the occurrence of neurological symptoms. Finally, this review discusses physical, pharmacological, and plastics substitution interventions designed to regulate MNPs transport in the brain and enhance neuroprotection, thereby reducing CNS toxicity of MNPs.\n\nID: 42086102\nTitle: Microplastics as an emerging environmental pollutant potentially leading to neurodegenerative diseases.\nAbstract: Microplastics (MPs), defined as plastic fragments less than 5\u00a0mm in diameter, are ubiquitous in the environment. As an emerging environmental pollutant, MPs can infiltrate the human body through multiple pathways, including inhalation, ingestion, dermal contact and bloodborne transmission.Correspondingly, MPs, which can penetrate the blood-brain barrier and enter the central nervous system (CNS), have been linked to the development of neurodegenerative diseases (NDs).In this review, we provide a comprehensive analysis of the environmental distribution of MPs, the pathways of entry into the human body, and the distribution within the CNS. Furthermore, we explore intrinsic factors influencing the neurotoxicity of MPs and elucidate the mechanisms underlying MPs-induced NDs, including Alzheimer's disease, Parkinson's disease, and Amyotrophic lateral sclerosis. Beyond mechanistic insights, we offer a novel perspective by exploring the potential adaptation of emerging environmental MPs detection and removal technologies for CNS applications. Ultimately, elucidating these mechanisms positions the reduction of MPs accumulation as a critical intervention point, highlighting the adaptation of environmental technologies as a promising strategy for the prevention and management of NDs.\n\nID: 42059992\nTitle: Micro- and Nanoplastics in the Human Brain: Mechanistic Plausibility, Translational Challenges, and Links to Neurological Disease Trends.\nAbstract: The exponential growth in plastic production since the mid-twentieth century has led to the pervasive presence of micro- and nanoplastics (MNPs) across ecosystems and human exposure pathways, coinciding with a rising global burden of neurological disorders. Increasing evidence demonstrates that MNPs are not confined to peripheral tissues but can accumulate even in the human brain, raising concerns about their potential contribution to neurological disease. This structured review synthesizes global trends in plastic production, environmental MNP burden, and human exposure, together with emerging data on brain accumulation, entry pathways, neurotoxic mechanisms, and key translational challenges. We present evidence showing that MNPs may cross brain barriers via multiple routes, including the blood-brain barrier, blood-cerebrospinal fluid barrier, olfactory, and circumventricular pathways, particularly under conditions of barrier vulnerability. Experimental studies reveal that once in neural tissue, MNPs may disrupt synaptic function, mitochondrial homeostasis, autophagy, and redox balance, while activating neuroinflammatory and gut-brain axis-mediated pathways. These mechanisms intersect with disease-relevant processes implicated in multiple neurological disorders whose global prevalence and societal burden have sharply increased over recent decades, including stroke, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, mood disorders, and neurodevelopmental conditions. Despite growing mechanistic plausibility, translational and human epidemiological evidence remains limited by methodological heterogeneity, a lack of standardized detection methods, and the absence of longitudinal clinical data/studies. We highlight critical analytical and translational gaps, public health implications, and priorities for longitudinal, biomarker\u2011driven studies needed to rigorously test whether MNPs may contribute to population\u2011level risk of neurological disease.\n\nID: 42013791\nTitle: RIPK1-driven calcium overload and lysosomal-mitochondrial dysfunction induce testicular necroptosis following DEHP exposure.\nAbstract: Di-(2-ethylhexyl) phthalate (DEHP) is a plasticizer widely used to enhance the flexibility and durability of plastic products. As an environmental endocrine disruptor, DEHP impairs male reproductive function. Its metabolite, mono-(2-ethylhexyl) phthalate (MEHP), mediates many toxic effects, but the mechanisms remain unclear. We hypothesized that DEHP induces testicular necroptosis through MEHP-mediated calcium overload and the RIPK1-regulated lysosomal-mitochondrial axis. Here, we reveal this novel mechanism. This study investigated DEHP-induced testicular damage, focusing on necroptosis and calcium (Ca\u00b2\u207a) signaling pathways. Sprague-Dawley rats were exposed to 250 and 750\u202fmg/kg DEHP for 5 weeks. Testicular damage was assessed via histopathology, testosterone measurement, and RNA sequencing (RNA-seq). A common Sertoli cell line was treated with MEHP to study Ca\u00b2\u207a overload, lysosomal membrane permeabilization (LMP), mitochondrial dysfunction, and necroptosis. Pharmacological inhibitors were employed to explore pathway involvement, including CA-074 Me (cathepsin B inhibitor), BAPTA-AM (Ca\u00b2\u207a chelator), and Nec-1 (RIPK1 inhibitor). DEHP caused testicular damage, including seminiferous tubule disorganization and reduced plasma testosterone. RNA-seq revealed necroptosis pathway enrichment, with upregulated RIPK1, RIPK3, MLKL, and PGAM5. MEHP induced Ca\u00b2\u207a overload, LMP, and mitochondrial dysfunction in Sertoli cells. CA-074 Me attenuated mitochondrial damage, while BAPTA-AM mitigated LMP. Nec-1 suppressed necroptosis-related proteins and restored blood-testis barrier integrity by upregulating ZO-1, Cx-43 and Claudin-11. DEHP exposure induced testicular necroptosis via MEHP-mediated Ca\u00b2\u207a overload-lysosomal-mitochondrial axis, regulated by RIPK1. These findings provide insights into DEHP reproductive toxicity.\n\nID: 41993512\nTitle: WDR44 drives de novo \u03b1-synuclein aggregation at the lysosomal membrane and promotes neuronal dysfunction in Parkinson's Disease.\nAbstract: The aggregation of \u03b1-synuclein (\u03b1-SYN) into Lewy bodies (LBs) is a central event in the pathogenesis of Parkinson's disease (PD) and related synucleinopathies1,2. Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons. We found that the initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44). Remarkably, we demonstrate that WDR44 knockdown markedly reduced de novo \u03b1-SYN aggregation in both neuronal cultures and in vivo, whereas WDR44 overexpression enhances \u03b1-SYN aggregation in PD patient-derived iPSC neurons. Consistent with its potential pathogenic involvement, WDR44 aberrantly accumulates in vivo and in the brains of PD patients, where it colocalizes with LB inclusions. Finally, we show that lysosome-associated \u03b1-SYN aggregates compromised lysosomal structure and function, leading to neuronal impairment, a phenotype worsened by WDR44 overexpression, linking early aggregation events to downstream toxicity. Together, these findings reveal the earliest dynamic stages of \u03b1-SYN oligomerization in living neurons and identify the WDR44-\u03b1-SYN interaction as a promising therapeutic target for reducing \u03b1-SYN pathology and enabling early intervention in PD.\n\nID: 41957923\nTitle: Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?\nAbstract: The enteric nervous system (ENS), a key component of the gut-brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)-a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or environmental contamination. Emerging evidence suggests that FCs may initiate or amplify neurodegenerative processes, yet their effects on the ENS and their impact in gut-to-brain communication remain insufficiently characterized. This systematic review synthesizes current evidence on FCs-induced effects on the ENS and its involvement in mediating neurotoxicity from dietary toxicants exposure. Following PRISMA guidelines, 67 studies were included pertaining to cellular or mammalian experimental models exposed to FCs via enteral routes, reporting ENS-related outcomes or studying vagal involvement in modulating FC toxicity. The main FCs evaluated were pesticides, toxins, bisphenols, acrylamide, manganese, and micro-/nanoplastics. Across studies, FCs consistently induced neurochemical remodeling of the ENS, activation of enteric glia, often coupled with intestinal alterations. Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain. Vagotomy models confirmed that disrupting ENS-CNS communication attenuates FC-related central neurotoxicity, supporting the involvement of food toxicants in gut-to-brain propagation of neurotoxic signals. These findings support the body-first hypothesis of PD and position the ENS as a critical, yet underinvestigated interface in exposome-related neurotoxicology. The review highlights research gaps and the need for improved models and long-term, low-dose studies reflecting realistic FC exposure.\n\nID: 41955522\nTitle: Nanoplastics and Neurodegeneration: A Roadmap From Mechanism to Causation.\nAbstract: Nanoplastics are ubiquitous by-products of global plastic production and have emerged as a potentially consequential yet insufficiently defined threat to health. Recent studies have revealed that these synthetic particulates can cross the blood-brain barrier, accelerate amyloid aggregation, impair microglial clearance, hijack the gut-liver-brain axis, and drive neuroinflammation-mechanisms central to neurodegeneration in Alzheimer's and Parkinson's disease. In addition, anionic nanoplastics can induce vascular endothelial leakiness, thereby harboring a paracellular route for their systemic and cerebral access. Yet causality remains unproven in implicating nanoplastics for neurodegeneration in the absence of standardized human exposure data, mechanistic specificity, and epidemiological evidence, especially considering the supra-environmental doses employed. Here, we synthesize current knowledge, examine barriers to causal understanding, and propose a roadmap to advance this emerging scientific frontier of great public concern and inform future strategies for sustainable materials innovation.\n\nID: 41812834\nTitle: Brain lipidomics identifies mitochondrial redox dysfunction and metabolic trade-offs associated with Parkinson's disease-like pathology induced by Nanoplastics exposure.\nAbstract: Growing nanoplastics exposure raises concern for neurotoxicity, particularly given recent evidence of plastic accumulation within human brain tissue a highly lipid enriched organ, yet effects on brain lipid metabolism remain poorly understood. Here, we employed high-resolution untargeted lipidomics to map brain lipid perturbations in Drosophila melanogaster chronically exposed to polystyrene nanoplastics (PS- NPs). PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids, notably cardiolipins and phosphatidylethanolamines, accompanied by increased diacylglycerols/triacylglycerols and monounsaturated fatty acids and by lipid droplet expansion. Guided by these lipidomic signatures, targeted biochemical assays demonstrated depolarized mitochondrial membrane potential, elevated mitochondrial reactive-oxygen species, inhibition of respiratory-chain complexes I and IV, and a shift in NAD(H) and NADP(H) redox couples toward a reduced state and increasing lipid peroxidation. This redox imbalance was accompanied by decreased tyrosine-hydroxylase expression, dopamine depletion, and impaired locomotor behavior, hallmarks of Parkinson's disease (PD)-like neurodegeneration. Dopaminergic neurochemistry was impaired (tyrosine hydroxylase and dopamine decreased), with concomitant reduction of GABA, and locomotor and circadian deficits emerged. Remarkably, co-treatment with the antioxidant N-acetylcysteine (NAC) restored mitochondrial membrane potential, reduced mitochondrial ROS and lipid peroxidation, normalized neutral lipid and MUFA accumulation, and rescued neurotransmitter levels and behavior. Stable-isotope tracing confirmed disrupted TCA cycle flux after NPs exposure that was rescued by NAC. Collectively, these findings reveal lipidomic remodeling as a critical link between environmental NPs exposure and PD-like pathology, highlighting mitochondrial redox-lipid interactions as early determinants and support redox-directed interventions to mitigate risk.\n\nID: 41751935\nTitle: Pathophysiological Roles of Two Intracellular P-Type ATPases: The Cancer-Associated Na+,K+-ATPase \u03b13 Isoform and the Parkinson's Disease-Related ATP13A2.\nAbstract: P-type ATPases constitute a diverse superfamily of ATP-driven transporters essential for ion homeostasis, membrane asymmetry, and organelle function. Among them, the P2-type Na+,K+-ATPase and the P5-type ATP13A2 have recently emerged as key regulators of cancer progression and neurodegeneration, respectively. In this review, we highlight new insights into the pathological roles of the Na+,K+-ATPase \u03b13 isoform (\u03b13NaK) in malignant cells and ATP13A2 in Parkinson's disease (PD). Cancer tissues frequently overexpress \u03b13NaK which is aberrantly localized to intracellular vesicles and undergoes adhesion-dependent intracellular trafficking. Upon cell detachment, \u03b13NaK translocates to the plasma membrane to sustain survival signaling, thereby promoting anoikis resistance and facilitating the persistence of circulating tumor cells (CTCs). Cardiac glycosides selectively inhibit \u03b13NaK at nanomolar concentrations, suppressing cancer cell proliferation through GLUT1 endocytosis, metabolic inhibition, and downregulation of THADA and LAT1, ultimately inducing anoikis in CTCs and reducing metastasis in vivo. Conversely, ATP13A2 is genetically linked to early-onset parkinsonism and regulates lysosomal integrity, polyamine homeostasis, and neuronal resilience. Recent animal studies demonstrate that adult-onset ATP13A2 loss causes progressive nigrostriatal degeneration, while heterozygous deficiency produces distinct age-dependent cognitive and \u03b1-synuclein phenotypes. Beyond its established role in polyamine transport, emerging evidence suggests that ATP13A2 can function as an H+,K+-ATPase-like transporter, contributing to proton and cation handling within the endolysosomal system. Together, these findings underscore the broader physiological and pathological significance of intracellular P-type K+-ATPases and highlight \u03b13NaK and ATP13A2 as promising therapeutic targets in cancer metastasis and PD.\n\nID: 41747943\nTitle: Degradation of alpha-synuclein/SNCA mRNA by RNautophagy.\nAbstract: \u03b1-Synuclein is a neuronal protein and main component of Lewy bodies, the pathological hallmark of Lewy body diseases such as Parkinson's disease and dementia with Lewy bodies. While the accumulation of \u03b1-synuclein in neurons is implicated in the pathogenesis of these disorders, the mechanisms underlying \u03b1-synuclein mRNA degradation remain poorly understood. RNautophagy is a lysosomal RNA degradation pathway in which RNA is directly taken up into lysosomes and subsequently degraded. SIDT2, a lysosomal membrane protein, mediates the uptake of RNA. In this study, we investigated whether SIDT2-mediated RNautophagy degrades \u03b1-synuclein mRNA. Knockdown of SIDT2 led to reduced degradation of \u03b1-synuclein mRNA, whereas overexpression of wild-type SIDT2 enhanced its degradation, suggesting its role in \u03b1-synuclein mRNA turnover. In contrast, overexpression of the RNA uptake-deficient S564A mutant did not enhance degradation, indicating that RNA uptake activity is required for SIDT2-mediated degradation of \u03b1-synuclein mRNA. Using a series of deletion mutants, we identified a guanine (G)-rich sequence within the 5' untranslated region (5'-UTR) of \u03b1-synuclein mRNA as a key determinant of SIDT2-dependent degradation. Furthermore, insertion of the G-rich sequence into the 5'-UTR of GFP mRNA promoted SIDT2-dependent degradation of GFP mRNA and reduced GFP protein expression. Taken together, these results indicate that SIDT2-mediated RNautophagy contributes to the degradation of \u03b1-synuclein mRNA via the G-rich region within the 5'-UTR. Our findings may also provide insights into the pathogenesis of Lewy body diseases.\n\nID: 41687947\nTitle: Molecular insights into physiological impact of micro- and nano-plastics on the digestive system and gut-brain axis.\nAbstract: Microplastics (MPs) and Nanoplastics (NPs) represent an alarming and persistent threat to global human health, owing to their resilience and ubiquity in the environment. Ingestion via contaminated food and water is the primary exposure route, resulting in the accumulation of MNPs in key organs such as the gastrointestinal tract (GI), liver, and pancreas, highlighting the urgent need to understand their potential cumulative and systemic effects. This review critically evaluates recent molecular-level insights into the physiological impacts of MNPs, with particular emphasis on the GI system and the intricate gut-brain axis. MNPs induce cellular toxicity through oxidative stress (OS) and mitochondrial dysfunction, which activate inflammatory and apoptotic pathways. Accumulation in the GI tract causes gut microbiota dysbiosis and a compromised intestinal barrier, and translocates systemically to the liver and pancreas, leading to hepatotoxicity, insulin resistance, and chronic inflammation. Crucially, the disruption of the gut barrier facilitates MNPs access to the central nervous system (CNS) via the gut-brain axis, leading to a breach of the Blood-Brain Barrier. CNS-accumulated MNPs induce neuroinflammation and neurotoxicity, accelerating neurodegenerative disorders such as Parkinson's, Alzheimer's, and multiple sclerosis. This review elucidates the complex mechanisms and highlights significant gaps in understanding MNPs risks, which are currently limited by the use of short-term animal and in vitro models, as well as a lack of precise human data. Future research should prioritize the development of standardized quantification techniques and advanced tracking methods to accurately assess the biodistribution, metabolism, and long-term health effects of MNPs. This approach will facilitate the development of targeted therapeutic interventions and preventive measures.\n\nID: 41675914\nTitle: RNA networks of lysosomal-related biomarkers in Parkinson's disease and their correlations with freezing of gait-associated genes.\nAbstract: Parkinson's disease (PD) is influenced by various factors, with lysosome function playing a critical role. However, the specific involvement of lysosome-related genes (LRGs) in PD remains unclear. This study aims to identify biomarkers specific to PD that exhibit robust disease prediction capabilities. Datasets for patients with PD, LRGs, and inflammation-related genes (IRGs) were retrieved from online databases. miRNAs and mRNAs within key modules were selected through Weighted Gene Co-expression Network Analysis (WGCNA), revealing strong associations with PD. A miRNA-mRNA network was constructed based on highly correlated PD-related LRGs (PD-LRGs) and miRNAs within these modules. Candidate genes were identified by intersecting target genes, differentially expressed genes (DEGs), PD-LRGs, and module-associated mRNAs. Machine learning and expression validation were employed to confirm these biomarkers. A nomogram was established, and its diagnostic performance was evaluated using a confusion matrix. Drug predictions were conducted based on these biomarkers. Spearman's correlation analyses were performed to assess the relationship between IRGs, freezing of gait (FOG)-related genes, and biomarkers. Molecular regulatory networks were constructed using datasets and online resources. Finally, clinical samples were collected for quantitative PCR (qPCR) validation of biomarker expression. Key modules related to PD were identified, comprising 190 miRNAs and 7,633 mRNAs. A miRNA-mRNA network was constructed based on 55 PD-LRGs and 181 miRNAs, resulting in the identification of 26 candidate genes strongly linked to lysosomal function. FGD4 and MAN2B1 were selected as biomarkers, and a gene expression-based risk prediction table was created. These biomarkers were significantly correlated with IRGs and several FOG-related genes. Gene localization analysis revealed that FGD4 and LRRK2, both critical to the FOG pathway, are located on chromosome 12. Drug prediction revealed that Tetrachlorodibenzodioxin and bisphenol A target both FGD4 and MAN2B1. qPCR analysis confirmed that FGD4 and MAN2B1 expression levels were significantly higher in patients with PD compared to healthy controls (p < 0.05). FGD4 and MAN2B1 act as lysosomal biomarkers associated with PD and exhibit strong correlations with genes involved in PD-related freezing of gait. This study offers novel insights into PD diagnosis.\n\nID: 41622607\nTitle: Zinc-Mediated Lysosomal Destabilization Links Mitochondrial Damage to Neuronal Death in a Cellular MPP+ Model of Parkinson's Disease.\nAbstract: Dysregulation of autophagy and lysosomal function is central to Parkinson's disease (PD), yet the upstream mechanisms leading to lysosomal failure remain unclear. Across primary mouse cortical neurons, MT-3 deficient primary mouse astrocytes, human iPSC-derived midbrain dopaminergic neurons, and Rho0 CHO cells lacking mitochondrial respiration, we investigated how mitochondrial stress perturbs zinc (Zn2+) homeostasis and lysosomal integrity. We identify intracellular zinc as a critical mediator linking mitochondrial dysfunction to lysosomal membrane permeabilization (LMP) and neuronal death. Inhibition of mitochondrial complex I by 1-methyl-4-phenylpyridinium (MPP+) elevated reactive oxygen species (ROS) and intracellular zinc, jointly driving LMP. Blocking either ROS or zinc markedly attenuated lysosomal damage and cell death, demonstrating that both act upstream of LMP. To define zinc regulation, we examined metallothionein-3 (MT-3), a brain-enriched zinc-binding protein. MT-3-deficient astrocytes were more vulnerable to MPP+ and zinc overload (ZnCl2) but paradoxically resistant to hydrogen peroxide (H2O2), suggesting that MT-3 buffers cytosolic zinc during mitochondrial injury or extracellular zinc influx yet can release bound zinc under oxidative conditions. Using Rho0 cells, we show that MPP+ toxicity depends on mitochondrial ROS, as loss of mitochondrial function nearly abolished cell death. However, Rho0 cells were highly sensitive to ZnCl2 and H2O2 and exhibited markedly reduced lysosomal abundance, indicating limited capacity to sequester zinc and increased susceptibility to zinc-mediated injury. These findings support a coordinated system in which lysosomes and zinc-binding proteins maintain zinc homeostasis. When cytosolic zinc rises, its accumulation within lysosomes induces LMP and accelerates cell death. Collectively, our results identify intracellular zinc as an upstream trigger of lysosomal dysfunction and neurodegeneration. Zinc-mediated LMP provides a mechanistic link between mitochondrial injury, impaired autophagic flux, and \u03b1-synuclein pathology in PD. Enhancing zinc homeostasis and lysosomal resilience may offer promising therapeutic strategies.\n\nID: 41580402\nTitle: Micro-nanoplastics and Parkinson's disease: evidence and perspectives.\nAbstract: With the intensification of global plastic pollution, the potential threats posed by micro- and nanoplastics (MPs/NPs) to human health have become a major concern. MPs/NPs enter the organism through ingestion, inhalation, and skin contact, subsequently accumulating in multiple organs-particularly the brain. Increasing experimental and epidemiological evidence implicates MPs/NPs in the development of Parkinson's disease (PD). Preclinical research models indicate that MPs/NPs may accelerate both the initiation and progression of PD by facilitating \u03b1-synuclein misfolding and aggregation, triggering neuroinflammatory cascades, elevating oxidative stress, and impairing mitochondrial function. To further investigate the causal role of MPs/NPs in PD, upcoming studies should emphasize well-designed, large-scale prospective cohorts to assess individual exposure to plastic-related pollutants, elucidate the pathways of MPs/NPs into the central nervous system, establish safety thresholds for their neurotoxicity, explore the correlation between exposure levels and central nervous system accumulation, clarify the temporal relationship between MPs/NPs accumulation and PD pathology and symptom onset, and identify the neuropathological mechanisms triggered by relevant concentrations of MPs/NPs. Such data will be instrumental in informing preventive and potentially interventional strategies, while offering actionable insights into the interaction between MPs/NPs and PD.\n\nID: 41576771\nTitle: Identification of pesticides associated with an increased risk of Parkinson's disease using a multi-screen approach.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disease characterized by aggregation and transmission of alpha-synuclein (\u03b1-syn) protein and loss of dopaminergic neurons. The etiology of PD is multifactorial, involving both genetic and environmental factors. Pesticide exposure has been associated with PD, and with thousands of registered pesticides in the United States, it is still unclear which of these chemically and structurally diverse pesticides confer this association. The population-based case-control Parkinson's, Environment, and Gene (PEG) study based in the California Central Valley, an agricultural hub servicing much of the nation, offers a promising opportunity to investigate this relationship and identify likely environmental risk factors contributing to PD risk. In this study, 62 pesticides with reported agricultural use in the Central Valley were independently evaluated in 2 cell-based assays testing for pesticides that promote \u03b1-syn transmission and alter autophagy. To further stratify and prioritize pesticide candidates, pesticides that were positive in the 2 cell-based screens (double hits) were filtered through a newly described pesticide-wide association analysis to agnostically identify relevant real-world exposures. Using these selection criteria, 6 pesticides were identified as triple hits and were tested for dopaminergic neurotoxicity in an in vivo zebrafish (ZF) model. Of these 6 pesticides, 4 pesticides contributed to aminergic neuron loss in ZF larvae. The majority of the pesticides identified in our screens have not previously been implicated as risk factors for PD but should be considered in future studies.\n\nID: 41560652\nTitle: Impact of Textile-Derived Micro- and Nanoplastics on Brain Health: An Emerging Environmental Risk.\nAbstract: Textile-derived micro- and nanoplastics (MNPs), primarily shed from synthetic fibers, such as polyester, acrylic, polyethylene, and nylon, constitute a widespread yet underexplored class of environmental pollutants. Despite their pervasive presence in indoor air, household dust, and the human body, these fibrous MNPs have received considerably less attention than polystyrene-based particles, resulting in a critical gap in our understanding of their potential health impacts. This review examines the growing evidence that textile-derived MNPs can translocate across biological barriers following inhalation or ingestion, reaching the brain via both direct olfactory pathways and systemic circulation through the blood-brain barrier. Experimental studies increasingly implicate MNPs in oxidative stress, neuroinflammation, and protein aggregation, processes central to the pathogenesis of neurodegenerative disorders such as Alzheimer's and Parkinson's disease. We also explore the therapeutic potential of natural bioactive compounds, including polyphenols and omega-3 fatty acids, in mitigating MNP-induced neurotoxicity. By consolidating current findings, this review highlights the urgency of advancing mechanistic studies, exposure assessment, and regulatory oversight to address the emerging threat of textile-derived MNPs to neurological health.\n\nID: 41488245\nTitle: Effects of endocrine disruptors on the neurological system.\nAbstract: There is increasing interest in endocrine disrupting chemicals because of the potential effects on neurological health. These chemicals are widely found in various consumer products and industrial processes, and can lead to serious disorders of the endocrine system by disrupting hormone synthesis, expression, and function. The aim of this review was to examine epidemiological and experimental findings by investigating the link between exposure to endocrine disrupting chemicals and adverse neurological outcomes. In the preparation of this review, a PubMed literature search was conducted using the words \"endocrine disruptors,\" \"neuroendocrine effects,\" \"neurobehavioral effects,\" and \"neurodevelopmental effects\" and articles containing relevant studies were examined. Recent studies have shown a strong correlation between exposure to endocrine disrupting chemicals and the development of neurodegenerative diseases such as Alzheimer's and Parkinson's disease, and neurodevelopmental diseases such as autism spectrum disorder and attention deficit hyperactivity disorder. The effects of common pollutants such as pesticides, bisphenol A, polychlorinated biphenyls, and heavy metals on the endocrine system have been especially emphasized. In conclusion, understanding the role played by endocrine disrupting chemicals in the development of neurological diseases will be of critical importance in the development of new strategies to prevent these diseases.\n\nID: 41482167\nTitle: Linking particulate matter exposure and neurological disorders: Evidence from epidemiology, biomarkers and mechanistic studies.\nAbstract: Exposure to particulate matter (PM) including fine (PM\u2082.\u2085), coarse (PM\u2081\u2080), and ultrafine particles (UFPM) has emerged as a critical environmental determinant of neurological disorders, including Alzheimer's and Parkinson's diseases, neurodevelopmental impairments, and cognitive decline. This review integrates evidence from 129 research articles (2002-2025) to elucidate the mechanistic, biomarker-based, and public health dimensions of PM-induced neurotoxicity. Mechanistic pathways include oxidative stress, neuroinflammation, mitochondrial dysfunction, and blood-brain barrier disruption, with documented structural and functional damage in brain regions such as the hippocampus and prefrontal cortex. PM\u2082.\u2085 serves as a carrier of neurotoxic metals (e.g., lead, cadmium, vanadium) and understudied organic toxicants (e.g., PAHs, pesticides), amplifying its pathogenic potential. Exposure occurs through the olfactory route, systemic circulation, and gut-brain axis, highlighting multiple entry points into the central nervous system. Biomarkers such as A\u03b2\u2084\u2082, phosphorylated tau (p-tau), and \u03b1-synuclein are elevated in experimental models, but require greater validation in human PM-exposed populations. Children and older adults represent the most vulnerable groups due to developmental sensitivity and cumulative neuroinflammatory burden, yet remain underrepresented in cohort studies. Geographic disparities further limit generalizability, with low- and middle-income countries underrepresented despite experiencing the highest PM burdens. Future research must advance longitudinal, cohort and life-course studies, multi-omics biomarker discovery, and real-world mixture toxicology to identify intervention targets. These findings call for urgent integration of air pollution control into public health strategies targeting neurological diseases, emphasizing prevention through regulation, early detection, and equity-focused research frameworks.\n\nID: 41357964\nTitle: Overall effects of microplastics on brain.\nAbstract: Microplastic (MP) and nanoplastic (NP) pollution represents a pervasive environmental issue, raising significant concerns regarding potential neurotoxicity and impacts on brain health. This review synthesizes recent research findings to provide a comprehensive overview of the effects of MPs/NPs on the brain. Evidence demonstrates that MPs/NPs can cross critical biological barriers, including the blood-brain barrier and the placenta, gaining access to the central nervous system (CNS) and the developing fetal brain, influenced by particle size, charge, and the biomolecular corona. Once present, MPs/NPs trigger multiple detrimental pathways, including oxidative stress, persistent neuroinflammation involving microglia and astrocytes, mitochondrial dysfunction leading to energy deficits, disruption of crucial neurotransmitter systems, and direct neuronal damage. Critically, NPs have been shown to promote the aggregation of proteins implicated in neurodegeneration, such as alpha-synuclein. These mechanistic disturbances translate into observable adverse outcomes in experimental models, ranging from cognitive impairments in learning and memory to behavioral abnormalities and pathologies resembling human neurodegenerative and neurodevelopmental disorders. Toxicity is modulated by particle characteristics, co-exposures, and host factors like age and sex, with indirect effects via the gut-brain axis also playing a significant role. While current evidence, primarily from animal models often using high doses, strongly indicates a neurotoxic potential, significant research gaps remain concerning human risk assessment under chronic, low-level environmental exposure conditions and the effects of environmentally aged, mixed-plastic particles. Future research should prioritize human studies, environmentally realistic exposure scenarios, and differentiating direct versus indirect neurotoxic mechanisms to accurately evaluate the threat MPs/NPs pose to human brain health.\n\nID: 41315817\nTitle: Alterations in neuroinflammatory and neurodegenerative biomarkers among long-term residents of a critically polluted area: a cross-sectional comparative study.\nAbstract: Ambient air pollution is increasingly recognized as an emerging risk factor for neurodegenerative diseases. However, evidence from community-based biomarker studies in highly polluted Indian regions remains sparse. To investigate the neuroinflammatory and neurodegenerative effects of chronic exposure to ambient air pollutants in long-term residents of a critically polluted area compared to a control region. This cross-sectional study included 203 adults (aged 40-60) residentially exposed to critical levels of air pollutants for \u2265\u200910 years and 202 geo-demographically matched controls residing at locations with very low / minimal air pollution. Air pollutant levels across all seasons were measured according standard protocols. Blood samples were analyzed for neurological biomarkers (viz. A\u03b21-42, Total Tau, \u03b1-Synuclein, brain-derived neurotrophic factor (BDNF), and glial fibrillary acidic protein (GFAP) using ELISA. Additionally, demographic, clinical (blood pressure, random blood sugar, lipid profile) and occupational data were collected. Appropriate, descriptive, comparative and regression statistics were applied after checking for the normality. Annual PM2.5 and ozone concentrations were significantly higher at the exposed site (PM2.5: 69.76\u2009\u00b1\u200915.99\u00a0\u00b5g/m\u00b3; ozone: 33.76\u2009\u00b1\u200911.58\u00a0\u00b5g/m\u00b3) compared to controls (p\u2009<\u20090.001). Exposed participants showed significantly elevated GFAP (p\u2009<\u20090.001) and A\u03b21-42 (p\u2009=\u20090.044), and significantly reduced levels of total tau, \u03b1-synuclein, and BDNF (p\u2009<\u20090.001), suggesting glial activation and impaired neuroprotection. Regression analyses confirmed exposure as a key predictor of biomarker variance, independent of age, BMI, blood pressure, and lipid levels. Chronic exposure to critical levels of ambient air pollutant is associated with subclinical alterations in neuroinflammatory and neurodegenerative plasma biomarkers. These findings underscore the potential for air pollution to contribute to neurological dysfunction and support the need for public health interventions and longitudinal studies. Further, plasma-based biomarkers replicated results previously reported using cerebrospinal fluid (CSF) and post-mortem tissue samples, thereby enabled minimally invasive detection of neurobiological alterations at the community level, supporting their potential utility in population-level environmental health research.\n\nID: 41274204\nTitle: Environmentally relevant concentrations of polystyrene nanoplastics induce Parkinson's-like neurotoxicity in C. elegans via oxidative stress.\nAbstract: This study reveals that environmentally relevant polystyrene nanoplastics (PS-NPs) induces Parkinson's disease (PD)-like pathology in Caenorhabditis elegans (C. elegans) through oxidative stress. Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions.\n\nID: 41252097\nTitle: Do microplastics play a role in the pathogenesis of neurodegenerative diseases? Shared pathophysiological pathways for Alzheimer's and Parkinson's disease.\nAbstract: The widespread presence of microplastics (MPs) in the environment has raised significant concerns about their potential impact on human health. As of 2023, the Ocean Conservancy estimates that adults may ingest up to 121,000 MPs annually. While the majority of these particles are cleared from the body, a small fraction can persist, as MPs are non-biodegradable and resist breakdown, posing long-term health risks that remain poorly understood. This review explores the emerging link between MP exposure and the development of neurodegenerative diseases, particularly Alzheimer's disease (AD) and Parkinson's disease [1]. MPs appear capable of triggering neurotoxic pathways, including activation of resident immune cells in the brain, oxidative stress, blood-brain barrier (BBB) disruption, mitochondrial dysfunction, and neuronal damage, which may contribute to neuroinflammation and disease progression. Specifically, six MP-related mechanistic pathways associated with AD were identified: BBB disruption, chronic inflammation, oxidative stress and ROS generation, mitochondrial dysfunction, impaired autophagy and proteostasis, and epigenetic alterations. Similarly, six pathways were implicated in PD: BBB disruption, oxidative stress in dopaminergic neurons, mitochondrial dysfunction, microglial-driven neuroinflammation, \u03b1-synuclein aggregation, and gut-brain axis [2] disruption. Ultimately, our findings underscore the urgent need for further research into the neurological consequences of chronic MP exposure in humans and highlight the importance of strengthening global policies to curb plastic pollution and mitigate its long-term health risks.\n\nID: 41218368\nTitle: Elevated blood microplastics and their potential association with Parkinson's disease.\nAbstract: Microplastic (MP) contamination in human blood and its potential link to Parkinson's disease (PD) remain poorly understood. In this study, we collected whole blood samples from 21 PD patients and 12 age- and sex-matched healthy controls under strict anticontamination protocols. A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs. Five polymer types-polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and nylon-66 (PA66)-were detected in the sample. The total MP burden was significantly greater in PD patients than in controls (21.36\u202f\u00b1\u202f8.42 vs. 13.56\u202f\u00b1\u202f5.92\u202f\u03bcg/g; p\u202f<\u202f0.01), with the greatest increases observed for PVC (1.49-fold), PP (2.74-fold) and PA66 (6.62-fold), whereas the PE and PS levels were not significantly different. LDIR and SEM analyses revealed diverse particle morphologies, with most polymers appearing as granular particles. In vitro assays further revealed that PVC and PP microplastics induced dopaminergic neuron apoptosis and increased the level of phosphorylated \u03b1-synuclein (p-\u03b1-syn), providing support for their potential neurotoxicity. Together, these findings indicate elevated blood MP levels in PD patients and offer preliminary evidence linking polymer exposure with PD-related neuronal vulnerability.\n\nID: 41196586\nTitle: Pathological Folding of \u03b1-Synuclein on Polystyrene Nanoplastic Revealed by Sum Frequency Scattering and 2D Infrared Spectroscopy.\nAbstract: The impact of micro- and nanoplastics (MNPs) on human health is a growing field of research. Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases.\n\nID: 41104042\nTitle: The microbiota-gut-brain axis in mental and neurodegenerative disorders: opportunities for prevention and intervention.\nAbstract: The microbiota-gut-brain axis (MGBA) is increasingly recognized as a critical regulator of brain health, influencing both neurodevelopment and age-related neurological decline. Disruptions in this axis, driven by gut dysbiosis, have been implicated in the pathogenesis of a wide range of neurodegenerative and neuropsychiatric disorders. This review synthesizes current evidence linking microbiota alterations to Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and stroke-including post-stroke cognitive impairment (PSCI), as well as major depressive disorder (MDD), bipolar disorder (BD), anxiety disorders, post-traumatic stress disorder (PTSD), and chronic fatigue syndrome (CFS). Common findings include reduced microbial diversity, depletion of short-chain fatty acid (SCFA)-producing genera, and enrichment of pro-inflammatory taxa. These changes contribute to neuroinflammation, blood-brain barrier (BBB) dysfunction, microglial activation, and neurotransmitter imbalances. The review further explores the neurotoxic effects of external factors such as radiation and xenobiotics on the MGBA. Despite disorder-specific variations, shared microbial and immunological mechanisms emerge across the spectrum of conditions. Importantly, we present current and emerging strategies aimed at restoring gut-brain communication, including dietary interventions such as fiber-rich and Mediterranean diets, SCFA supplementation, probiotics, and fecal microbiota transplantation (FMT). These approaches show promise in alleviating cognitive and emotional symptoms, modulating immune responses, and potentially slowing disease progression. By integrating mechanistic insights with therapeutic perspectives, this review underscores the gut microbiota as a modifiable factor in neuropsychiatric and neurodegenerative disease. Targeting the MGBA offers a novel, translational approach to intervention that may ultimately contribute to healthier brain aging and improved outcomes across the lifespan.\n\nID: 40938039\nTitle: Nano- and Microplastics in the Brain: An Emerging Threat to Neural Health.\nAbstract: Nano- and microplastics (NMPs), with nanoplastics posing higher risks due to their smaller size and greater capacity for cellular and subcellular penetration, are being referred to as ubiquitous environmental neurotoxicants, due to their ability to pass through biological barriers, including the blood-brain barrier (BBB) and nasal olfactory epithelium, and to remain lodged in neural tissue. Upon uptake, such particles disturb neuronal homeostasis by multiple converging pathways, including oxidative stress, mitochondrial dysfunction, pathological protein aggregation, and chronic neuroinflammation, all closely involved with the molecular signatures of neurodegenerative disorders (Alzheimer's, Parkinson's, Amyotrophic Lateral Sclerosis-ALS). In addition to their neurotoxicity, recent findings suggest that NMPs could disturb synaptic communication and neuroplasticity, thereby compromising the brain's capacity to recover from an injury, a trauma, or neurodegeneration, thus impacting the progression of the disease, our ability to treat it and eventually the efficacy of rehabilitation approaches. Despite these findings, our understanding remains hampered by analytical issues, the scarcity of standard detection methods, and a total lack of longitudinal studies in humans. This review combines multidisciplinary evidence on brain-plastic interactions and calls for accelerated advances in our ability to monitor bioaccumulation in humans, and to integrate neurotoxicology paradigms in the assessment of this underappreciated but growing threat to brain health.\n\nID: 40906862\nTitle: Lewy body dementia promotion by air pollutants.\nAbstract: Evidence links air pollution to dementia, yet its role in Lewy body dementia (LBD) remains unclear. In this work, we showed in a cohort of 56.5 million individuals across the United States that fine particulate matter (PM2.5) exposure raises LBD risk. Mechanistically, we found that PM2.5 exposure led to brain atrophy in wild-type mice, an effect not seen in \u03b1-synuclein (\u03b1Syn)-deficient mice. PM2.5 exposure generated a highly pathogenic \u03b1Syn strain, PM2.5-induced preformed fibril (PM-PFF), with enhanced proteinase K resistance and neurotoxicity, resembling \u03b1Syn LBD strains. PM2.5 samples from China, the United States, and Europe consistently induced proteinase-resistant \u03b1Syn strains and in vivo pathology. Transcriptomic analyses revealed shared responses between PM2.5-exposed mice and LBD patients, underscoring PM2.5's role in LBD and stressing the need for interventions to reduce air pollution and its associated neurological disease burden.\n\nID: 40675497\nTitle: Insights into the toxic effects of micro-nano-plastics on the human brain and their relationship with the onset of neurological diseases: A narrative review.\nAbstract: The intensive production and use of plastics, poor biodegradability and inadequate recycling have caused excessive and alarming environmental pollution. This has led to the inevitable intake by humans, through different routes, of small plastic particles, the micro and nano-plastics (MNPs) with sizes ranging from nanometers (<1000\u202fnm) to micrometers (from 5\u202fmm to 1\u202f\u00b5m). MNPs can cause harmful effects in human tissues and organs, contributing to the early onset of aging and various age-related diseases. A growing body of evidence supports this toxic role of MNPs. In this regard, it has been shown that their different chemical and physical properties, including different chemical composition with different additives, different size, shape, solubility and ability to interact with metals and microbial agents, as well as the duration of multiple exposures, modulate their toxic action. In the brain, as documented mainly by studies conducted on brain tissues of deceased individuals, nanosized nanoparticles (NPs) of mostly 50\u202fnm or smaller, made of polyethylene, bioaccumulate, causing damage. The mechanisms involved do not seem to be fully understood. However, studies on animal models and human cell cultures using plastic particles made of synthetic polystyrene, of slightly larger dimensions, partially clarify this aspect. They demonstrated that these particles have the unique ability to cross the blood-brain barrier and evoke neurotoxicity, through the activation of pathways that determine oxidative stress, inflammation, apoptosis, altered synthesis of neurotransmitters, endocrine molecules and key enzymes related to nerve conduction, and able to influence the gut-brain axis. Despite the paucity of studies conducted directly in humans, this review collects a growing body of evidence demonstrating that exposure to MNPs, and essentially NPs, can damage neurons. This could lead to alterations in learning, memory and behaviour, and could evoke additional potential negative impacts, contributing to amplifying neuroinflammation and the onset of neurodegenerative disorders, such as Alzheimer's and Parkinson's diseases. Preventive approaches and measures to limit their use and human exposure, as well as potential therapeutic strategies, are also suggested.\n\nID: 40639550\nTitle: Micro(nano)plastics in the brain: Epigenetic perturbations in progression to neurodegenerative diseases.\nAbstract: As global plastic production escalates, micro(nano)plastics (MNPs) have become pressing ecological and biomedical concerns. These pollutants are increasingly implicated in the pathogenesis of neurodegenerative diseases. Due to their nanoscale size and surface reactivity, MNPs can cross the blood-brain barrier, accumulating in neural tissues. Once internalized, they disrupt neuronal homeostasis by inducing oxidative stress, mitochondrial dysfunction, and chronic neuroinflammation, key processes in neurodegenerative progression. Mitochondria, central to neuronal energy and redox regulation, are particularly vulnerable, leading to impaired ATP production, elevated ROS, and pro-apoptotic signaling. Recent studies reveal that MNPs also induce epigenetic changes, including aberrant DNA methylation, histone modifications, and dysregulation of non-coding RNAs. These alterations can result in synaptic instability, persistent transcriptional reprogramming, and heightened susceptibility to diseases like Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis. The mitochondrial epigenome is a vital target of MNP-induced disruption, offering potential biomarkers like methylated mtDNA and microRNAs for early diagnosis and prognosis. Understanding the molecular mechanisms behind these epigenetic alterations is essential for developing practical diagnostic tools and therapies. This review provides a comprehensive overview of MNP-induced neurodegeneration, focusing on mitochondrial and epigenetic disruptions. Moreover, it explores emerging biosensing technologies for detecting MNP-induced epigenetic alterations, highlighting the urgent need for further investigation to fully understand the neurotoxic potential of MNPs and develop preventive and therapeutic strategies for mitigating their effects on brain health.\n\nID: 40474178\nTitle: Polystyrene nanoplastics trigger pyroptosis in dopaminergic neurons through TSC2/TFEB-mediated disruption of autophagosome-lysosome fusion in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a sporadic neurodegenerative disorder with a rising incidence. Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD.\n\nID: 40459748\nTitle: The neurotoxic threat of micro- and nanoplastics: evidence from In Vitro and In Vivo models.\nAbstract: Micro- and nanoplastics (MPs/NPs), ubiquitous contaminants in ecosystems and food chains, have emerged as a significant concern due to their potential neurotoxic effects on human health. Here, we conducted a systematic review of the existing literature, which included 26 studies providing evidence from cellular and animal studies on the risks posed by MPs/NPs to the nervous system. In vitro studies reveal that MPs/NPs can disrupt the integrity of the blood-brain barrier, penetrate neurons and glial cells, impair cell membrane integrity, and induce cytotoxic effects. These plastic particles trigger oxidative stress, inflammation, and mitochondrial dysfunction, alter signaling pathways, and disrupt neuronal communication, potentially leading to neurological dysfunction, cognitive deficits, and neurodegenerative disorders like Alzheimer's and Parkinson's diseases. Animal models corroborate these findings, demonstrating behavioural changes, memory impairment and neurotransmitter imbalances following exposure to MPs/NPs. Although the evidence in humans is limited, the growing body of hazard data underlines the potential risks associated with chronic exposure and accumulation of MPs/NPs in the nervous system. This highlights the urgent need for further research to elucidate the mechanisms of neurotoxicity, as well as stringent regulatory measures to restrain plastic pollution and safeguard neurological health.\n\nID: 40459174\nTitle: Plastamination: A Rising Concern for Parkinson's Disease.\nAbstract: \n\nID: 42395216\nTitle: Human Exposure to Micro- and Nanoplastics and Their Potential Neurological Implications: A Systematic Review of Emerging Evidence.\nAbstract: The growing prevalence of micro- and nanoplastics (MNPs) in the environment elicits concerns about their possible impact on human neurological health. Although studies on animals have suggested neurotoxic effects, evidence from humans is still scarce. This systematic review gathers existing human data to assess the presence, types, detection techniques, and neurological consequences of MNPs in different biological matrices. A comprehensive review was performed on peer-reviewed research concentrating on human studies that report the detection of MNPs in biological tissues and fluids. Four qualifying studies were identified: one clinical observational study, two cadaveric analyses, and one quasi-experimental trial. The data collected encompassed demographics, detection methods, types and concentrations of polymers, biological matrices examined, and neurological biomarkers. MNPs were observed in cerebrospinal fluid (CSF), faeces, urine, olfactory bulbs (OBs), and in brain, liver, and kidney tissues from postmortem cases. The polymers that were reported most frequently were polyethylene (PE) and polypropylene (PP). The detection methods included micro-Fourier transform infrared spectroscopy (\u00b5FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Although the available evidence is limited, emerging findings indicate the possible accumulation of MNPs in the human central nervous system (CNS), particularly in individuals with dementia or compromised blood-brain barrier (BBB) integrity. Relationships were noted between MNP exposure and disruptions in the BBB, inflammatory markers, and alterations in the gut-brain axis. This review consolidates the findings and emphasizes the need for further exploration of human exposure to MNPs and their possible accumulation in neural tissues. Although there is variability in methodologies used in the reviewed articles, PE and PP stand out as the primary polymers of concern. While a direct causal relationship cannot yet be confirmed, the results highlight the necessity for improved detection methods, larger sample sizes, and long-term studies to better understand the impact of MNPs on neuroinflammation and neurodegeneration.\n\nID: 42349722\nTitle: From plastics to pathology: The neurodegenerative impact of Bisphenol-A on Alzheimer's disease.\nAbstract: Bisphenol-A (BPA), a ubiquitous component of polycarbonate plastics and epoxy resins, has emerged as a significant environmental risk factor for neurodegenerative diseases, particularly Alzheimer's disease (AD). It is widely detected in the environment and humans due to its extensive use in plastics and epoxy resins for consumer products such as bottles, containers, and tableware. This review synthesizes current evidence on the molecular and cellular mechanisms by which BPA exposure may contribute to neurotoxicity and AD pathogenesis. We discuss how BPA disrupts endocrine signalling, induces oxidative stress, promotes neuroinflammation, and impairs synaptic plasticity, all of which are implicated in the development and progression of AD. The review also examines the impact of BPA on amyloid-beta accumulation, tau pathology, and cognitive decline, integrating findings from animal models, in vitro studies, and epidemiological research. Furthermore, we address the limitations of BPA alternatives and highlight emerging therapeutic and preventive strategies. This study highlights the pathogenic molecular mechanisms involved, offering a foundation for understanding BPA-induced neurodegenerative processes. By bridging the gap between environmental exposure and neuropathology, this article underscores the urgent need for regulatory action and further research to mitigate the neurodegenerative risks associated with BPA in plastics.\n\nID: 42310725\nTitle: Targeting lysosomal pH restores mitochondrial quality control in GBA1-mutant Parkinson's disease.\nAbstract: Heterozygous mutations in the glucocerebrosidase gene (GBA1), which encodes the lysosomal enzyme \u03b2-glucocerebrosidase (GCase), are a genetic risk factor for Parkinson's disease (PD). The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate. Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for\u00a0GBA1-PD .\n\nID: 42294809\nTitle: Microplastics-Induced Gut Microbiota Dysbiosis Accelerates Alzheimer's-Like Pathology and Cognitive Decline via the Gut-Brain Axis.\nAbstract: Alzheimer's disease (AD) is incurable and increasingly attributed to gene-environment interactions. Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration.\n\nID: 42259955\nTitle: Aging in a highly polluted world: challenges and solutions to prevent Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder globally and a leading cause of disability and death among the elderly. As populations age worldwide, the epidemiological burden of AD is expected to more than double by 2050, surpassing 150\u00a0million affected individuals. While genetic susceptibility, particularly the apolipoprotein E \u03b54 (APOE4) allele, modulates individual risk, most AD cases are late-onset and shaped by complex interactions between genetic background and modifiable environmental exposures. Environmental pollution has emerged as a critical and potentially preventable contributor to this burden. The 2024 Lancet Commission on Dementia Prevention, Intervention, and Care has identified 14 modifiable risk factors, with air pollution explicitly included. Drawing on evidence from human epidemiological cohorts, experimental animal models, and in vitro neuronal/glial systems, the present review aims to synthesize mechanistic evidence linking environmental pollutant classes to AD-relevant neuropathology. The review examines the growing body of evidence linking major categories of environmental pollutants (ambient particulate matter, heavy metals, pesticides, PFAS, and emerging contaminants including microplastics and nanoplastics) to AD risk and pathogenesis. Special attention is given to studies showing that the characteristic neuropathological features of AD may emerge in children and young adults chronically exposed to heavily polluted urban environments, which highlights critical concerns about when and how these changes develop throughout life. Shared mechanistic pathways through which environmental pollutants promote neurodegeneration are discussed, including neuroinflammation, oxidative stress, blood-brain barrier disruption, tau kinase dysregulation, epigenetic reprogramming, and gut-brain axis dysbiosis. The review also examines the amplifying role of biological aging on neurotoxic vulnerability and proposes a comprehensive, multi-level prevention framework addressing individual exposure reduction, clinical risk identification, and population-level policy interventions.\n\nID: 42210609\nTitle: The TRPM2-PARP-1 Axis Involvement in Bisphenol A and Nonylphenol-Induced Ferroptosis in Trigeminal Ganglion Cells.\nAbstract: Environmental contaminants like bisphenol A (BPA) and nonylphenol (NP) are recognized neurotoxicants; however, the molecular mechanisms underlying their impact on sensory ganglia, specifically the trigeminal ganglion (TG), remain critically underexplored. This study explored the potential of BPA and NP to drive neuronal injury and ferroptosis linked to oxidative stress, acting through the transient receptor potential melastatin 2 (TRPM2)-poly (ADP-ribose) polymerase-1 (PARP1) signaling axis. Forty-two adult male Wistar rats were allocated into seven groups (control, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] NP, and low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA\u2009+\u2009NP) and treated orally for 21\u2009days. We employed a combinatorial approach of biochemical assays and immunohistochemistry to evaluate oxidative stress markers, ferroptosis hallmarks (glutathione peroxidase 4 [GPX4], solute carrier family 7 member 11 [SLC7A11], and transferrin receptor [TfRC]), apoptotic mediators (Caspase-3 and Caspase-9), and inflammatory cytokines, as well as the expression of TRPM2 and PARP-1. Results demonstrated that BPA and NP exposure triggered a robust, dose-dependent accumulation of reactive oxygen species (ROS) and lipid peroxidation, concomitant with downregulation of anti-ferroptotic proteins (GPX4 and SLC7A11) and upregulation of TfRC. This toxic insult simultaneously activated apoptotic and inflammatory cascades. Crucially, TRPM2 and PARP-1 were significantly upregulated, implying a potential role for the TRPM2-PARP-1 axis as an upstream modulator of oxidative stress-induced ferroptosis and neuroinflammation. Collectively, these findings provide novel mechanistic insights into phenol-induced neurotoxicity, highlighting the inhibition of the TRPM2-PARP-1 axis as a promising therapeutic strategy to mitigate environmental neurodegeneration in sensory neurons.\n\nID: 42185558\nTitle: Protective effects of gastrodin against bisphenol A-induced dopaminergic dysregulation and cognitive impairment in rats.\nAbstract: Gastrodin (GAS) is a potent neuroprotective compound extracted from the traditional Chinese medicinal herb Gastrodia elata Blume. However, its role in mitigating bisphenol A (BPA)-induced dopaminergic dysfunction and cognitive impairment remains insufficiently explored. Many studies have shown that BPA exposure causes neurodegeneration via mechanisms involving dopaminergic system dysfunction, oxidative stress, and neuroinflammation. Therefore, the present study aimed to investigate whether GAS mitigates the effects of BPA-induced cognitive impairment through neuroinflammation in a rat model. Weanling male\u00a0Wistar rats exposed to BPA (50\u00a0\u00b5g/kg b.wt.\u2009\u00d7\u200930\u00a0days, po) were subsequently treated with GAS at two dose levels (30 and 60\u00a0mg/kg b.wt., ip\u2009\u00d7\u20097\u00a0days). After 24\u00a0h, neurobehavioral functions (Barnes maze and Y-maze tests), cresyl violet staining, and ultrastructural analysis were performed, demonstrating significant memory deficits and neuronal degeneration in BPA-exposed rats. In contrast, GAS treatment significantly improved memory impairment and reduced neuronal cell death in the prefrontal cortex (PFC). mRNA, protein, and immunohistochemical expression of inflammatory markers such as tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), (Iba-1), glial fibrillary acidic protein (GFAP), and nuclear factor kappa B-p65 (NF\u03baB-p65) were significantly increased in BPA-treated rats, indicating enhanced glial activation and neuroinflammation, whereas GAS effectively attenuated these alterations. Additionally, dopaminergic markers such as\u00a0tyrosine hydroxylase (TH), dopamine transporter-1/solute carrier family 6 member 3 (DAT-1/SLC6A3), and dopamine receptor D4 (DRD4) were significantly downregulated following BPA exposure and were restored by GAS treatment. Overall, findings suggested that\u00a0GAS exerts protection against BPA-induced neurotoxicity by suppressing NF-\u03baB-mediated neuroinflammatory response and modulating dopaminergic signaling, thereby improving cognitive and neuronal outcomes in the PFC.\n\nID: 42105707\nTitle: NLRP3 inflammasome dysregulation by endocrine-disrupting chemicals and heavy metals: Developmental programming, sex differences, and inflammaging across the lifespan.\nAbstract: Environmental exposure to heavy metals and endocrine-disrupting chemicals (EDCs) activates the NLRP3 inflammasome, driving chronic inflammation that worsens or may underlie cardiovascular disease, neurodegeneration, and accelerated aging. This review examines the molecular mechanisms by which lead, cadmium, mercury, arsenic, bisphenol A, phthalates, and dioxins modulate NLRP3 signaling. Lead and cadmium activate NLRP3 through mitochondrial dysfunction and oxidative stress, whereas mercury and arsenic suppress inflammasome assembly by preventing apoptosis-associated speck-like protein containing a CARD (ASC) oligomerization. EDCs engage receptor-mediated pathways: aryl hydrocarbon receptor (AhR) activation directly represses NLRP3 transcription, yet bisphenol A and phthalates override this suppression through NF-\u03baB activation. Developmental timing critically determines outcomes such as prenatal exposures epigenetically programing persistent NLRP3 dysregulation. Sex hormones have been shown to modulate distinct inflammatory landscapes: estrogen suppresses NLRP3 via ER\u03b2-dependent mechanisms, while testosterone amplifies inflammasome-dependent pathology. The skin serves as a primary interface for environmental chemical exposure and cutaneous NLRP3 activation. NLRP3-deficient mice exhibit 34% increased lifespan, and pharmacological inhibition with MCC950 extends lifespan in progeria models. The CANTOS trial demonstrated that targeting inflammation through IL-1\u03b2 neutralization confers cardiovascular benefits in high-risk humans. These findings position NLRP3 as a central integrator through which the chemical exposome accelerates inflammaging and identify inflammasome inhibition as a therapeutic strategy for environmental disease prevention.\n\nID: 42097318\nTitle: Polystyrene nanoplastics drive neuronal senescence via PP2A-B56\u03b3-targeted p-Ebp1Ser335 dephosphorylation-mediated ribosome biogenesis dysfunction.\nAbstract: Nanoplastics (NPs) exhibit neurotoxicity, yet the precise molecular mechanisms remain elusive. In this study, we established a human-relevant polystyrene nanoplastics (PS-NPs, 50\u202fmg\u202fkg-1) oral exposure model in C57BL/6 mice in vivo and a neuro-immune microglial-neuron co-culture system (HMC-3/SH-SY5Y cells) in vitro to dissect these mechanisms. We demonstrate that PS-NPs exposure triggers microglial M1 activation and drives neuronal senescence. Mechanistically, PS-NPs activate the protein phosphatase 2A (PP2A)-B56\u03b3 subunit, which selectively dephosphorylates the ribosome biogenesis regulator ErbB3-binding protein 1 (Ebp1) at Ser335. This post-translational modification reduces Ebp1 nucleolar localization, suppresses 47S pre-ribosomal RNA transcription, and induces nucleolar stress. Consequently, the p53/p21 pathway is engaged, promoting neuronal senescence. Pharmacological inhibition of PP2A with LB-100 restored ribosome biogenesis, prevented neuronal senescence, and rescued cognitive deficits and neurodegenerative phenotypes in PS-NP-exposed mice. This is the first study to identify the PP2A-B56\u03b3-p-Ebp1Ser335-ribosome biogenesis axis as a novel cascade mechanism driving PS-NP-induced neuronal senescence. Our findings offer a targetable strategy to mitigate nanoplastics-associated neurodegeneration.\n\nID: 42030847\nTitle: Coexposure to heat stress and polystyrene nanoplastics induces neuroinflammation and cognitive impairment via oxidative stress-NLRP6-pyroptosis axis.\nAbstract: Global warming and plastic pollution constitute interconnected environmental threats. However, their combined neurotoxic effects, particularly in the context of climate change-driven temperature rise, remain unexplored, posing a critical knowledge gap for environmental health risk assessment. To address this gap, we developed a mouse model subjected to coexposure to heat stress (36 \u00b0C, 4\u202fh/day) and well-characterized polystyrene nanoplastics (PS-NPs, 60\u202fnm, 10\u202fmg/kg/day) for 30 consecutive days. Multidisciplinary approaches, including behavioral testing, histopathological analysis and molecular profiling, were employed to assess cognitive dysfunction and its underlying mechanisms. Compared with the single-exposure groups, coexposure induced pronounced cognitive deficits in mice, which were concomitant with hippocampal neurodegeneration, bloodbrain barrier (BBB) compromise, and exacerbated hippocampal oxidative stress. Transcriptomic profiling and subsequent validation revealed a novel role for oxidative stress-induced NLR family pyrin domain containing 6 (NLRP6) inflammasome activation in driving microglial pyroptosis, which exacerbates neuroinflammation through a feedforward loop. The administration of the antioxidant N-acetylcysteine (NAC) attenuated these pathological alterations by suppressing oxidative damage, thereby rescuing cognitive performance. This study elucidates a novel mechanism whereby heat stress and PS-NP coexposure synergistically disrupt neurological homeostasis via redox-sensitive inflammatory pathways, offering critical insights for the development of preventive strategies against combined environmental neurotoxicity.\n\nID: 42022192\nTitle: Exposure to Nanoplastics Disrupts Neurotransmitter Release in Rat Hippocampal Neurons.\nAbstract: Plastics are used broadly for various applications, and their degradation and fragmentation have led to widespread accumulation of nanoplastics in the environment. Although nanoplastics are ubiquitous and intractable in the environment and in organisms, their potential health impacts remain unclear. Emerging evidence showed that nanoplastics can cross the blood-brain barrier and accumulate in the brain. However, the effects of nanoplastics on neuronal health and functions in the brain are poorly understood. Here, we examined the effects of nanoplastic exposure on neurotransmitter release by measuring FM 4-64 (a lipophilic styryl dye) release from synaptic vesicles during electrical stimulation after exposing rat hippocampal neurons to 1-10 \u03bcg/mL of fluorescent polystyrene nanoplastics with an average diameter of 42 nm. We found that nanoplastics accumulated in the presynaptic terminal of hippocampal neurons and reduced stimulation-induced FM 4-64 release in a dose-dependent manner. Furthermore, nanoplastics decreased Ca2+ elevation in the presynaptic terminal of hippocampal neurons during electrical stimulation. Our results suggest that accumulated nanoplastics in the brain can impair neuronal functions by disrupting neurotransmitter release and Ca2+ dynamics in the presynaptic terminal of neurons, which could eventually lead to neurodegeneration.\n\nID: 42009103\nTitle: Nanoplastics exposure accelerates the progression of osteoarthritis via lysosomal destabilization-mediated pyroptosis.\nAbstract: Nanoplastics (NPs), as emerging environmental pollutants, are increasingly detected in human musculoskeletal tissues, but their impact on osteoarthritis (OA) pathogenesis remains unclear. This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA.\n\nID: 41980172\nTitle: Polystyrene Microplastics Induced Hepatocytes Pyroptosis, Apoptosis and Ferroptosis via GSDMD-N-Mediated Mitochondrial Damage.\nAbstract: Microplastics (MPs), as emerging food contaminants, have been established to exert adverse effects on the liver. However, the precise toxicological mechanisms remain elusive. Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes. This study provided novel mechanistic insights into MPs-induced hepatotoxicity, identifying GSDMD-N as a potential central hub coordinating multiple cell death modalities.\n\nID: 41904737\nTitle: Assessment of female fertility and oocyte quality in mice after exposure to polystyrene microplastics and polybrominated diphenyl ethers, alone and in combination.\nAbstract: With the extensive use of plastics and brominated flame retardants, polystyrene microplastics (Ps-MPs) and polybrominated diphenyl ethers (PBDEs) frequently co-occur in the environment, raising growing concerns about their combined reproductive hazards. However, the synergistic toxicity of Ps-MPs and PBDEs on female fertility and oocyte quality remains insufficiently characterized. In this study, we established a 28-day oral exposure model in female ICR mice to evaluate the effects of Ps-MPs, PBDE-47, and their co-exposure on ovarian function, oocyte meiotic competence, and reproductive outcomes. Both Ps-MPs and PBDE-47 alone reduced ovarian weight, decreased antral follicles, increased follicular atresia, and markedly lowered ovulation and litter size, whereas co-exposure produced the most severe impairments. At the oocyte level, exposure significantly reduced germinal vesicle breakdown and first polar body extrusion, increased abnormal spindle formation and erroneous kinetochore-microtubule attachments, and suppressed TPX2 expression and \u03b1-tubulin acetylation. Cortical F-actin polarization, spindle migration, and membrane localization of JUNO and ovastacin were also disrupted, indicating widespread defects in meiotic and membrane maturation. Mechanistically, Ps-MPs and PBDE-47 induced a decline in mitochondrial membrane potential, aberrant mitochondrial distribution, excessive lipid accumulation, and Ca\u00b2\u207a imbalance, accompanied by autophagosome accumulation, lysosomal dysfunction, elevated ROS, increased \u03b3-H2AX signals, and enhanced Annexin V labeling, ultimately triggering DNA damage and apoptosis. All alterations were most pronounced under co-exposure. Collectively, Ps-MPs and PBDE-47 synergistically impair female fertility by converging on mitochondrial dysfunction, autophagy-lysosome imbalance, and oxidative stress-mediated DNA damage, leading to substantial reductions in oocyte quality. These findings provide key mechanistic evidence for evaluating reproductive risks associated with real-world mixtures of microplastics and persistent organic pollutants.\n\nID: 41871642\nTitle: Activation of the MKK4/7-JNK-c-Jun axis mediates bisphenol F-induced neurodegeneration and behavioural alteration in adult zebrafish.\nAbstract: Bisphenol F (BPF), widely utilised as an industrial substitute for bisphenol A (BPA), has recently surfaced as a global environmental pollutant owing to its chemical stability, vast application, and rising identification throughout several ecological compartments. Notwithstanding its reputation as a safer alternative, emerging data indicates that BPF may produce similar or even more pronounced toxicological consequences. This study found that adult zebrafish exposed to environmentally relevant concentrations of BPF displayed significant anxiety-like behaviour, diminished cognitive performance, and decreased scototaxis preference, indicating increasing neurobehavioral dysfunction. These behavioural changes suggest that prolonged BPF exposure disrupts neuronal circuit integrity and emotional regulation. Biochemical tests indicated a significant decline in total antioxidant capacity, coupled with diminished activities of catalase and superoxide dismutase, as well as increased levels of lipid peroxidation. This array of alterations indicates significant oxidative stress and impaired antioxidant defence mechanisms in the zebrafish brain. At the molecular level, a duration-dependent activation of the MKK4/7-JNK-c-Jun signalling cascade was noted, aligning with the onset of pro-apoptotic MAPK pathways under oxidative circumstances. Supporting these findings, histological evaluations verified significant neuronal loss and chromatin condensation, especially in the periventricular grey matter, a region essential for adult neurogenesis. Collectively, our findings suggest that extended exposure to BPF triggers oxidative stress-mediated apoptotic signalling, resulting in neurodegeneration and notable behavioural deficits. This study highlights the pressing necessity to reevaluate the environmental safety and regulatory oversight of BPF, considering its widespread application and proven ability to impair vertebrate neurological health.\n\nID: 41865970\nTitle: Fluorene\u20119\u2011bisphenol\u2011associated endoplasmic reticulum stress linked to oxidative stress, apoptosis and autophagy in SH\u2011SY5Y cells.\nAbstract: Fluorene-9-bisphenol (BHPF), an alternative to bisphenol A (BPA), is widely used to make polyester polymers and serves as an important organic intermediate in synthetic plastics. While diverse toxic effects of BHPF have been documented in the literature, its effects on neurons, potential neurotoxicity, and underlying molecular mechanisms remain unclear. In this study, we reported that BHPF (10, 25\u202f\u00b5M) inhibited neuronal SH-SY5Y cell viability, increased lactate dehydrogenase (LDH) release, and induced cell death in a dose-dependent manner. BHPF exposure increased intracellular reactive oxygen species (ROS) and mitochondrial reactive oxygen species (mtROS) levels, decreased mitochondrial membrane potential, reduced the expression of cytochrome C oxidase subunit 4 (COX4) and mitochondrial protein 1 (MFN1), but upregulated Bax, Caspase-3, Caspase-8 and initiated apoptosis. In addition, BHPF treatment led to the accumulation of acidic vacuoles in the cells and increased the expression of autophagy regulatory proteins, including Beclin-1, LC3II, ATG5 and p62. Moreover, BHPF could trigger endoplasmic reticulum stress (ER stress), and ER stress inhibitor taurodeoxycholate (TUDCA) reversed the BHPF-induced oxidative stress, apoptosis and autophagy. Thus, our in vitro data indicate that ER stress may be linked to the oxidative stress, apoptosis, and autophagy observed in nerve cells following BHPF exposure. These findings offer preliminary insights into cellular processes that could help elucidate the potential role of nerve cells in BHPF-associated degenerative diseases.\n\nID: 41863649\nTitle: Molecular mirror: reflecting the complexity of Parkinson's disease.\nAbstract: Parkinson\u2019s disease (PD) is a multifaceted neurodegenerative disorder driven by a complex interplay of genetic and environmental factors that disrupt normal cellular function. A hallmark of PD pathology is the abnormal accumulation of alpha-synuclein protein, leading to the formation of Lewy Bodies and the degeneration of dopaminergic neurons. Critical proteins like Akt1 and glycogen synthase kinase-3 beta (GSK-3\u03b2) are vital for cell survival and apoptosis regulation; their dysfunction adversely affects the health of dopaminergic neurons, accelerating neurodegeneration. Additionally, PARK2 (parkin) and PTEN-induced kinase 1 (PINK1) are crucial for mitochondrial function and energy homeostasis. In PD, mutations in these genes are reported and impair mitochondrial quality control, making neurons more vulnerable to stress and exacerbating disease progression. The enzyme glucocerebrosidase (GBA), crucial for lysosomal function, is also linked to PD, with mutations in the GBA gene associated with increased SNCA accumulation and faster disease progression. Interestingly, tau protein, typically associated with Alzheimer\u2019s Disease, is also present in Parkinson\u2019s disease pathology, suggesting a potential overlap in the mechanisms driving these neurodegenerative diseases. The vesicular monoamine transporter 2 (VMAT2) plays a crucial role in dopamine regulation, and its malfunction can render dopaminergic neurons more vulnerable to degeneration. In conclusion, PD represents a complex interplay of genetic, protein-related, and environmental factors leading to progressive neurodegeneration. Understanding these molecular mechanisms is crucial for developing biomarkers and advanced therapies. Ongoing research is essential for creating treatments that effectively manage symptoms, slow disease progression, and improve patient quality of life, ultimately transforming the lives of those affected.\n\nID: 41815072\nTitle: Dopamine and Rotenone Modulate \u03b1-Synuclein Phase Separation and Liquid to Solid Transition.\nAbstract: Liquid-liquid phase separation (LLPS) of \u03b1-Synuclein (\u03b1-Syn) is recognized as an early biophysical event driving pathological aggregation in Parkinson's disease (PD). Although 10%-15% of PD cases are due to familial mutations, the remaining cases are sporadic, often linked to various factors, like pesticides and metals. For example, rotenone and dopamine are known to be involved in PD pathology and are suggested to cause changes in \u03b1-Syn protein homeostasis, although the mechanism by which they influence \u03b1-Syn and cellular toxicity is largely unknown. In this work, we demonstrate that both dopamine and rotenone promote the LLPS of \u03b1-Syn. Although rotenone promotes the liquid-to-solid transition almost instantaneously, dopamine, however, maintains a liquid state for a long time and rather delays the solidification process, unlike \u03b1-Syn alone. Similarly, exposure to both toxicants resulted in faster LLPS in SH-SY5Y cells. Interestingly, irrespective of their impact on material properties, rotenone promotes the faster formation of oligomers and amyloid fibrils, while dopamine exhibits oligomer formation and delayed fibrillation, both of which result in higher cytotoxicity. Our results provide new insight into the molecular processes underlying PD by indicating that endogenous dopamine stress and environmental toxicants converge on phase-separation dynamics as a common mechanism of \u03b1-Syn pathology.\n\nID: 41769917\nTitle: NIR-II Imaging-Guided Photothermal Activation of a TRPV4-Targeted Nanoplatform Delivering Cycloastragenol to Promote Microglia Reprogramming and \u03b1-Synuclein Clearance in Parkinson's Disease.\nAbstract: Current therapies for Parkinson's disease (PD) fail to concurrently address \u03b1-synuclein (\u03b1-syn) aggregation and microglia-mediated neuroinflammation. Herein, we engineer a near-infrared-II (NIR-II) phototheranostic nanoplatform, CAG/FD1080@MM-aTRPV4, for synergistic regulation of microglial function and real-time monitoring of PD pathology. We first encapsulated cycloastragenol (CAG), a bioactive compound derived from Astragalus, into liposomes. These liposomes were then fused with biomimetic microglial membrane-loaded FD1080 photothermal imaging agent, followed by modification with a transient receptor potential vanilloid 4 (TRPV4)-targeting antibody. In vitro studies using \u03b1-syn-treated cultured microglia and in vivo studies in an \u03b1-syn-overexpressing mouse model collectively demonstrate the efficacy of our strategy. It not only enables precise microglial delivery of CAG to reprogram metabolism but also sustains lysosomal function via photothermal activation of the TRPV4/CaMKK\u03b2/AMPK/mTOR pathway, ultimately enhancing phagocytosis. Importantly, the encapsulated FD1080 (for microglial tracking) and an anti-\u03b1-syn-conjugated indocyanine green (anti-\u03b1-syn-ICG) probe enable dual-modality NIR-II photoacoustic-fluorescence imaging, allowing real-time visualization of both microglial dynamics and \u03b1-syn clearance. This work pioneers a photothermal immunomodulation strategy using a Chinese herb-derived compound, presenting a versatile theranostic platform and novel mechanistic insights for microglia-targeted PD therapy.\n\nID: 41758265\nTitle: Rab8a dysregulation in Parkinson's disease: A convergence of genetic and molecular pathologies.\nAbstract: Parkinson\u2019s disease (PD) is a progressive neurodegenerative disorder characterized by dopaminergic neuron loss in the substantia nigra and \u03b1-synuclein (\u03b1Syn) accumulation in Lewy bodies. Genetic mutations in upstream regulators of cellular pathways, such as LRRK2, VPS35, TMEM230, and PINK1, are increasingly implicated in dysregulating Rab8a GTPase function, potentially disrupting its roles in \u03b1Syn homeostasis, lysosomal clearance, autophagy, membrane trafficking, lipid metabolism, and ciliogenesis. Rab8a protectively interacts with S129-phosphorylated \u03b1Syn to promote the formation of less toxic aggregates, whereas its depletion impairs lysosomal function and \u03b1Syn degradation. Gain-of-function LRRK2 and VPS35 mutations phosphorylate Rab8a at threonine 72 (Thr72), exacerbating PD pathology. In contrast, loss-of-function TMEM230 mutations have been linked to reduced Rab8a levels in some models, impairing vesicular trafficking and autophagy, whereas loss-of-function PINK1 mutations abolish serine 111 (Ser111) phosphorylation in a PINK1-dependent manner. This loss of phosphorylation impairs Rab8a activation (via reduced Rabin8 GEF binding) and removes a regulatory constraint on pathogenic LRRK2-mediated Thr72 phosphorylation. In vivo, LRRK2 and PINK1 mutations mechanistically converge on striatal ciliogenesis defects, reducing glial-derived neurotrophic factor (GDNF) signaling and neuroprotection. Although preclinical data strongly implicate Rab8a dysregulation as a downstream effector of multiple PD-associated genetic pathways, direct evidence of altered Rab8a expression or phosphorylation in human PD brain tissue is currently lacking. This review emphasizes the emerging role of Rab8a in PD pathogenesis and highlights its therapeutic potential.\n\nID: 41751535\nTitle: Nuclear and Mitochondrial Epigenetic Mechanisms Underlying Neurodegeneration and Gut-Brain Axis Dysregulation Induced by Micro- and Nanoplastics.\nAbstract: The increasing and global distribution of microplastics and nanoplastics (MPs/NPs) in the environment has led to concern about their potential influence on human health, especially on the gastrointestinal tract, as well as the brain. MPs/NPs could traverse epithelial and endothelial barriers, disrupt the gut microbiota, and perturb the microbiota-gut-brain axis, leading to systemic inflammation and possibly extending neurodegenerative processes. Experimental models now demonstrate that MPs/NPs reprogram nuclear and mitochondrial epigenetics-DNA methylation, histone modifications, non-coding RNAs, and mitochondrial DNA regulation-in gut, immune, and neural cells with downstream effects on synaptic function, neuronal survival, and protein aggregation. This mechanistic narrative review integrates preclinical and emerging human evidence of how MPs/NPs compromise intestinal barrier integrity, modulate gut microbiota composition, affect the blood-brain barrier, and converge on oxidative stress, neuroinflammatory signaling, and cell death pathways within the central nervous system across key neurodegenerative diseases. Overall, the review offers an integrated model in which environmental exposure to chronic MPs/NPs disrupts the microbiota-gut-brain axis and drives concurrent nuclear and mitochondrial epigenetic remodeling, lowering the threshold for neurodegeneration in susceptible individuals, while outlining candidate mechanistic readouts that require exposure-specific validation in human-relevant models and longitudinal cohorts.\n\nID: 41741261\nTitle: Micro- and nanoplastics in neurological dysfunction.\nAbstract: Plastic particles can interfere with the nervous system and are increasingly recognised as a global health concern. This review encompasses recent findings on the impact of plastic particles on brain health, including studies in humans, rodents, nematodes, and zebrafish. We discuss how plastics can impact cellular metabolism, affect developmental brain processes, and increase vulnerability to neurodevelopmental disorders and depression. Additionally, we review the potential of plastic particles to interact with the immune system and trigger pathological protein aggregation, enhancing susceptibility to neurodegeneration. Finally, we evaluate knowledge gaps that should be addressed to better understand the long-term impacts of plastic particles on the nervous system and neurological disorders.\n\nID: 41739966\nTitle: Polystyrene Microplastics Disrupt the Gut-Brain Axis via Activating Brain TLR4 and Impair Hippocampal Synapses through the TLR4/MyD88/NF-\u03baB Pathway.\nAbstract: Polystyrene (PS) is one of the most widely used microplastics (MPs) globally. However, the neurotoxicity mechanisms triggered by polystyrene microplastics (PS-MPs) have yet to be elucidated. This study explored the damage induced by PS-MPs to the intestinal and central nervous system (CNS) and the potential mechanism. The results showed that PS-MPs exhibited size-dependent bioaccumulation with enhanced barrier penetration at submicron scales (500 nm > 1 \u03bcm \u226b 5 \u03bcm). Paradoxically, 1 \u03bcm PS-MPs demonstrated maximum neuroinflammation despite inferior biodistribution to 500 nm particles. Mechanistically, both sizes induce gut dysbiosis-mediated barrier disruption, elevating circulatory LPS that translocates across compromised BBB. This triggers excessive activation of the TLR4/MyD88/NF-\u03baB pathway, subsequently inducing a surge in pro-inflammatory cytokines, ultimately leading to synaptic lesions in the hippocampal region. Our findings established smaller PS-MPs (\u22641 \u03bcm) as latent neurodegeneration risk factors, demanding urgent assessment of chronic exposure consequences.\n\nID: 41708985\nTitle: Protocol of ASPro-PD: a phase 3 trial of ambroxol to slow progression in genetically stratified Parkinson's disease.\nAbstract: Genetic studies have identified the GBA1 gene as a significant genetic risk factor for Parkinson's disease (PD), with 10-15% of PD patients carrying GBA1 variants. GBA1 variants affect the glucocerebrosidase (GCase) enzyme, often leading to reduced GCase activity and associated altered lysosomal function, implicated in PD pathogenesis. Ambroxol, a small molecule widely used for respiratory diseases, has emerged as a potential therapeutic agent for PD, acting by increasing GCase activity. A phase 2 trial demonstrated ambroxol's safety and efficacy in penetrating cerebrospinal fluid (CSF) and engaging with its target in PD patients, including those with GBA1 variants. We present the protocol of the ASPro-PD trial, a phase 3, multicentre, randomised, double-blind, placebo-controlled trial, aimed at evaluating whether high-dose ambroxol improves motor and non-motor function in PD patients. The trial will enrol 330 PD patients with confirmed GBA1 status and the primary outcome will be the combined score of parts I, II, and III of the Movement Disorders Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS). The secondary outcomes include safety, impact on PD symptoms, and quality of life. Mechanistic and exploratory outcomes include biomarkers related to GCase activity, blood, and CSF biomarkers. This trial is the largest to date to study the effect of ambroxol in PD, utilise a genetically stratified PD population and will provide robust estimates of the efficacy of ambroxol in slowing PD clinical progression.\n\nID: 41703390\nTitle: Pathological Protein Targets in Parkinson's Disease: Progress Towards the Development of Disease-Modifying Therapies.\nAbstract: Parkinson's disease (PD) is a common neurodegenerative movement disorder that currently has no disease-modifying therapies. Over the past two decades, there has been a substantial acceleration in the knowledge of how genetics underlies PD risk. This has given rise to pathological protein targets that can be therapeutically targeted. In particular, there is compelling evidence for developing therapeutic strategies targeting alpha-synuclein, leucine-rich repeat kinase 2 (LRRK2) and glucocerebrosidase (GCase). These proteins are implicated in lysosomal function and may contribute to the accumulation of the hallmark pathological forms of alpha-synuclein that define PD. This review highlights current progress on PD therapies targeting these proteins as they attempt to make their way through the clinical trial pipeline, with unique and distinctive approaches being used for each target. Progress is being made in both immunotherapy and small molecule approaches to reduce aggregated forms of alpha-synuclein in the brain, with the aim to stop the propagation of disease. Pathogenic mutations in LRRK2 result in overactivation of the enzyme's catalytic kinase activity, and consequently kinase inhibitors that aim to reduce LRRK2 activity are in late phase clinical trials. In contrast, PD-associated mutations in GCase generally result in impaired lysosomal GCase activity, and thus small molecule chaperones and allosteric activators of GCase are in advanced development and clinical trials. Although these approaches seem to be generally tolerated by participants in phase I studies, challenges remain in progressing these promising therapies through phase II and beyond.\n\nID: 41662903\nTitle: Micro-nanoplastics in the central nervous system: Evidence, mechanisms and perspectives.\nAbstract: Environmental exposure to micro-nanoplastics (MNPs) has emerged as a significant concern for neurological health. This review synthesizes evidence that MNPs translocate the blood-brain barrier (BBB) and induce neurotoxicity through mechanisms including oxidative stress, neuroinflammation, mitochondrial dysfunction, and neurotransmitter disruption. In rodent models, these disturbances lead to pathological and behavioral deficits relevant to neurodegeneration, neurodevelopmental disorders, and psychiatric conditions. Critically, we evaluate emerging clinical studies confirming the presence of MNPs within human central nervous system tissues and fluids. Our review then provides a critical appraisal of these human studies, highlighting their methodological limitations and inconsistent application of quality assurance/quality control (QA/QC) protocols, which currently constrain robust exposure assessment and causal inference. While clinical correlations exist between MNP levels and markers of BBB integrity, cognitive function, and stroke severity, establishing causality requires standardized detection methods and rigorous QA/QC integrated with longitudinal cohort studies. Generating such reliable evidence is paramount for informing public health strategies aimed at mitigating plastic exposure.\n\nID: 41596551\nTitle: Identification of KHS-101 as a Transcription Factor EB Activator to Promote \u03b1-Synuclein Degradation.\nAbstract: Neurodegenerative disorders are increasingly linked to a progressive decline in lysosomal function. Activating Transcription Factor EB (TFEB), a master regulator of lysosomal biogenesis and autophagy, has therefore emerged as a promising therapeutic strategy to enhance cellular clearance in these conditions. In this study, we identified KHS-101 as a novel TFEB activator through a high-throughput screen of blood-brain-barrier-permeable small molecules. We demonstrated that KHS-101 promotes TFEB nuclear translocation, enhances lysosomal biogenesis and proteolytic activity, and increases autophagic flux. Furthermore, KHS-101 significantly accelerates the degradation of pathogenic A53T mutant \u03b1-synuclein in a cellular model of Parkinson's disease, suggesting its potential to mitigate \u03b1-synuclein-mediated proteotoxicity and hold neuroprotective potential. Our findings identify KHS-101 as a potent TFEB activator and highlight the therapeutic potential of modulating the autophagy-lysosomal pathway for treating Parkinson's disease and related disorders.\n\nID: 41520051\nTitle: Targeting microglial inflammation in Parkinson's disease: irisin activates PAFAH1B1-RAGE ubiquitination and TFEB-dependent autophagy to alleviate neurodegeneration.\nAbstract: Investigate irisin's therapeutic potential in Parkinson's disease (PD). Clinical data from 120 PD patients and 120 controls were analyzed. MPTP-induced PD mice and LPS-stimulated BV2 microglia models were used. In vivo, mice were divided into control, PD, and PD + Irisin groups for behavioral and histological assessments. In vitro, LPS-stimulated BV2 cells were treated with irisin or PBS. RNA sequencing, immunohistochemistry, and Western blot evaluated autophagy, inflammation, and ubiquitination pathways. PD patients exhibited increased TNF-\u03b1 and IL-1\u03b2 but decreased irisin levels. In PD mouse models, irisin improved motor deficits, increased nigrostriatal neuron numbers, restored tyrosine hydroxylase expression, and reduced \u03b1-synuclein aggregation. It also suppressed microglial inflammation and promoted anti-inflammatory polarization. Mechanistically, irisin enhanced autophagic flux, regulated RAGE ubiquitination mediated by PAFAH1B1, and inhibited neuroinflammation via the TFEB-NLRP3 axis. Specifically, PAFAH1B1 regulated RAGE expression through K61 and K169 sites on K48-linked polyubiquitin chains. Additionally, irisin restored lysosomal function by promoting TFEB nuclear translocation, enhancing NLRP3 inflammasome degradation, and reducing inflammatory factor secretion, thus alleviating neuroinflammation. Irisin alleviates PD pathology by modulating autophagy and ubiquitination pathways, suggesting its potential as a novel immunomodulatory target for PD.\n\nID: 41520027\nTitle: Disruption of intracellular iron homeostasis through mitochondrial dysfunction associated with suppression of ATP 13A2 expression.\nAbstract: Elevated iron in the SNpc may play a key role in Parkinson's disease (PD) neurodegeneration, yet the underlying mechanism accounting for this iron accumulation is unclear. Although iron is an essential element, excessive amounts produce toxicity. Here, we focused on the role of iron and ATP13A2, the causative gene of PARK9 neurodegeneration with brain iron accumulation, using a cellular model. ATP13A2 deficiency resulted in impaired lysosomal function and iron accumulation in cell organelles. Further, we found dysfunction of mitophagy, which is involved in managing mitochondrial quality, as well as mitochondrial damage. Furthermore, we confirmed a decreased heme synthesis capacity, which is important to maintain intracellular iron homeostasis. Overall, our study indicates that lysosome-derived mitochondrial impairment can disrupt intracellular iron homeostasis in a cell model of PD pathology. This could help better understand the mechanisms underlying PD.\n\nID: 41516359\nTitle: Mitophagy-NLRP3 Inflammasome Crosstalk in Parkinson's Disease: Pathogenic Mechanisms and Emerging Therapeutic Strategies.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra and pathological \u03b1-synuclein aggregation. Growing evidence identifies chronic neuroinflammation-particularly NLRP3 inflammasome activation in microglia-as a central driver for PD onset and progression. Misfolded \u03b1-synuclein, mitochondrial dysfunction, and environmental toxins act as endogenous danger signals that prime and activate NLRP3 inflammasome, leading to caspase-1-mediated maturation of IL-1\u03b2 and IL-18 and subsequent pyroptotic cell death. Impaired mitophagy, due to defects in PINK1/Parkin pathways or receptor-mediated mechanisms, permits accumulation of dysfunctional mitochondria and release DAMPs, thereby amplifying NLRP3 activity. Studies demonstrate that promoting mitophagy or directly inhibiting NLRP3 attenuates neuroinflammation and protects dopaminergic neurons in PD models. Autophagy-inducing compounds, along with NLRP3 inhibitors, demonstrate neuroprotective potential, though their clinical translation remains limited due to poor blood-brain barrier penetration, off-target effects, and insufficient clinical data. Additionally, the context-dependent nature of mitophagy underscores the need for precise therapeutic modulation. This review summarizes current understanding of inflammasome-mitophagy crosstalk in PD, highlights major pharmacological strategies under investigation, and outlines its limitations. Future progress requires development of specific modulators, targeted delivery systems, and robust biomarkers of mitochondrial dynamics and inflammasome activity for slowing PD progression.\n\nID: 41483106\nTitle: Hepatotoxic mechanisms of functionalized nanopolystyrene: decoding the role of ionic surface groups.\nAbstract: With annual global plastic production exceeding 400 million tons, nanoscale polystyrene particles (nPS) have become a major health concern due to their bioaccumulation capacity and ability to cross biological barriers. Surface-charged nPS variants (cationic, anionic, and neutral) show distinct biodistribution patterns, yet the mechanisms underlying their systemic damage remain incompletely understood. This study aimed to investigate the systemic injury mechanisms of nPS with different surface charges. Mice were exposed to fluorescently labeled cationic (amino-modified), anionic (carboxyl-modified), and neutral nPS via drinking water (25\u00a0mg/mL) for 3\u00a0weeks. Tissue distribution was analyzed using fluorescence microscopy; pathological changes were assessed via hematoxylin-eosin (HE) staining; metabolic perturbations were detected by metabolomic profiling. Mechanistic investigations were performed using metabolomics, flow cytometry, and molecular assays in AML12 hepatocytes and vascular endothelial cells. Fluorescence microscopy showed neutral nPS accumulated in the vascular endothelium of the stomach, intestine, and lung via passive diffusion, while cationic/anionic nPS penetrated hepatic sinusoids through charge-mediated interactions. HE staining revealed severe liver injury, with no significant abnormalities in other tissues. Metabolomic profiling indicated disrupted hepatic amino acid and lipid metabolism, depleted antioxidants (e.g., vitamin E and glutathione), and induced oxidative stress (evidenced by elevated hydroxy fatty acids). In hepatocytes, nPS-induced endoplasmic reticulum (ER) stress triggered excessive reactive oxygen species (ROS) production, inhibiting SLC7A11-mediated cystine uptake and glutathione synthesis, leading to disulfide stress (\u03b2-actin disulfide mispairing) and ferroptosis (GPX4 inactivation and iron accumulation). In contrast, neutral nPS induced endothelial cell senescence via phagolysosome dysfunction, causing lysosomal membrane permeabilization and \u03b2-galactosidase release. This study identifies a \"charge-specific injury\" paradigm: charged nPS induce hepatocyte ferroptosis via an ER stress-disulfide stress cascade, while neutral nPS trigger endothelial senescence through phagocytic dysfunction. These findings provide critical insights for the biosafety assessment of nanoplastics and identify potential targets for preventing plastic pollution-related liver diseases.\n\nID: 41472781\nTitle: Comparative neurotoxicity of Bisphenol-A and aluminum chloride in adult zebrafish: Behavioral disruption and region-specific neuropathology under chronic exposure.\nAbstract: The escalating environmental presence of neuroactive pollutants such as Bisphenol-A (BPA) and aluminum chloride (AlCl\u2083) raises critical concerns regarding their long-term effects on cognitive health. This study presents a comparative neurotoxicity model using adult zebrafish (Danio rerio) exposed to a 21-day static immersion protocol with environmentally relevant doses (2 and 4\u202fmg/L). Neurobehavioral changes were assessed using the novel tank diving test (NTDT) and a color-based T-maze test, combined with detailed histopathological scoring. BPA induced markedly stronger neurobehavioral and neuropathological effects than AlCl\u2083. BPA exposure caused dose-dependent reductions in swim velocity and distance travelled, heightened anxiety-like behavior, and cognitive inflexibility with reduced exploratory transitions and spatial learning. Histology revealed extensive vacuolation, neuronal pyknosis, and perineural congestion in the telencephalic and diencephalic regions, confirming widespread neurodegeneration. In contrast, AlCl\u2083 produced moderate impairments, with neuropathology primarily confined to the cerebellum and thalamus. These differential effects suggest distinct mechanisms: BPA may disrupt synaptic plasticity and hypothalamic-pituitary-interrenal (HPI) axis signaling, whereas AlCl\u2083 likely involves mitochondrial dysfunction and tauopathy. By integrating behavioral phenotyping with region-specific neuropathology, this model highlights the translational relevance of adult zebrafish for regulatory toxicology and human health risk assessment of aquatic neurotoxicants.\n\nID: 41404032\nTitle: From environment to brain: the role of microplastics in neurobehavioral disorders.\nAbstract: In recent years, the pervasive presence of microplastics has attracted significant attention from the scientific community, particularly concerning their potential implications for human health. Current literature suggests that microplastics may adversely affect the nervous system, with emerging evidence linking them to neurobehavioral disorders. However, many questions remain regarding the pathways of their environmental exposure, the specific effects on neurobehavior, and the underlying mechanisms of their impact. This review aims to explore the routes through which humans are exposed to microplastics, monitor behavioral changes associated with microplastic exposure, and examine how these particles infiltrate the body and traverse the blood-brain barrier. Several perspectives will be considered in assessing the potential mechanisms by which microplastics may influence neurobehavioral disorders, including oxidative stress, neurotransmitter regulation, and neuroplasticity. The article concludes by summarizing the effects of microplastics on neurobehavioral disorders, such as neurodegeneration and mood disorders, while analyzing the latest research findings. The primary objective of this study is to elucidate the neurotoxic effects of microplastics and their potential biological mechanisms, as well as to provide new insights and recommendations for future research in this domain.\n\nID: 42406727\nTitle: Rate of IPG Placement for Sacral Neuromodulation in Patients With CNS Pathology.\nAbstract: Little is known about the efficacy of sacral neuromodulation in patients with central nervous system (CNS) pathology. The objective of this study was to assess the rate of internal pulse generator (IPG) implantation for sacral neuromodulation (SNM) in patients with CNS pathology with overactive bladder (OAB) or urinary retention in women. This was a retrospective study utilizing the TriNetX Research Network platform, using the years 2010 to 2025, collected on March 27, 2025. Two separate queries of the data set were performed to obtain our cohorts due to the differences in inclusion criteria and endpoints. For our OAB cohorts, adult (18 years or older) female participants were included in the study if they had OAB, urge incontinence, or urgency of urination via International Classification of Diseases (ICD) codes. We then developed 6 cohorts for (1) dementia, (2) Parkinson disease, (3) stroke, (4) multiple sclerosis (MS), (5) normal pressure hydrocephalus (NPH), and (6) an aggregate cohort. We utilized ICD codes and medication codes for the aforementioned diagnoses. Each cohort had either stage 1 SNM placement or peripheral nerve evaluation (PNE) via Current Procedural Terminology (CPT) codes after 2010. Control participants included all female adult participants without any of the aforementioned neurological diagnoses. The primary outcome was the rate of neurostimulator device IPG placement within 1 month of stage 1 or PNE. A second group of cohorts was developed for urinary retention. Adult female participants were included in the study if they had retention of urine. We developed 4 cohorts: (1) dementia, (2) Parkinson disease, (3) stroke, and (4) MS, utilizing the previous ICD codes and medications. Each cohort had either stage 1 SNM placement or PNE placed after 2010. The primary outcome was the rate of neurostimulator device IPG placement (CPT code 64590) within 3 months of stage 1 or PNE. Compared with the control (4,337 of 7,805, 55.56%), there was a statistically significant reduction in the rates of SNM IPG implantation in patients with dementia (179 of 375, 47.73%) and the aggregate (483 of 984, 49.09%). There was no significant difference in SNM IPG implantation for the Parkinson disease, stroke, MS, and NPH cohorts. In the urinary retention group, compared with the control population, there were no statistically significant differences in the rate of SNM IPG implantation in the cohorts. Our study suggests that SNM has equal efficacy in patients with CNS pathology with OAB or urinary retention, similar to the nonneurogenic population, except in patients with dementia, who have lower rates of IPG implantation for OAB.\n\nID: 42406561\nTitle: 'Partnering With Poise': A Preliminary Study of an Alexander Technique-Based Group Course for Informal Care Partners.\nAbstract: Informal care partners often experience role-engulfment and decreased quality of life. Alexander technique is a non-exercise, cognitive embodiment training common in performing arts. Studies have shown it to have physical benefits including pain reduction and improved balance and coordination, as well as non-physical benefits like increased wellbeing, confidence, and agency. We assessed feasibility and preliminary efficacy of an Alexander-based group course for care partners of people living with neurodegenerative disease. We conducted a single-arm multi-site study of eight Alexander-based group courses for informal care partners of people living with Parkinson's (63 began course; 45 remained at 6-month follow-up). Classes met weekly for 90-120\u00a0min over 10\u00a0weeks in community settings in North Carolina, USA. Outcomes were assessed before and after the intervention and 6\u00a0months later. Self-regulation strategies were taught through group, partnered, and individual activities. Participants practiced interrupting automatic reactions to stressful stimuli in everyday contexts and learned skills to observe and improve psychomotor patterns. Outcome measures included course attendance and retention, anonymous course evaluations, three cognitive measures, a balance assessment, and 12 self-report measures. Alpha was set at 0.0031 to correct for multiple comparisons. Course attendance was 85%. Retention was 84%. Participants enjoyed the course and the group interactions. Executive function, balance, and emotional self-regulation improved significantly and remained high at follow-up. This replicable Alexander technique-based group course shows promise as a novel self-management intervention to improve quality of life for long-term care partners of people living with neurodegenerative disease. Possible mechanisms are explored.\n\nID: 42405844\nTitle: A Phase 1 Study of Convection-Enhanced Delivery of Intraputaminal AAV2-GDNF in Advanced Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder. Neurotrophic therapeutic approaches have been limited in part by incomplete delivery to the putamen. We developed image-guided convection-enhanced delivery with real-time monitoring to improve intraputaminal distribution of neurotrophic gene therapy. To evaluate the 5-year safety and tolerability of bilateral putaminal delivery of adeno-associated virus serotype 2 encoding glial cell line-derived neurotrophic factor (AAV2-GDNF), and to describe exploratory long-term clinical outcomes. This was a single-center, open-label, phase 1, dose-escalation study in adults with advanced PD. Thirteen participants received bilateral putaminal infusions across three dose cohorts (six low-dose, six medium-dose, one high-dose) and were followed for 5\u2009years. Adverse events, including serious adverse events, were collected, and their relationship to the study agent was determined. Longitudinal clinical outcomes were analyzed with a mixed-effects model. Across follow-up, 562 adverse events were recorded; 45 were considered possibly or probably related to the study drug. The 13 serious adverse events that occurred were not attributed to the study drug. One participant died 45\u2009months after infusion from aspiration pneumonia following cervical spine surgery at an outside institution. The study drug had a mean putaminal coverage of 26%\u2009\u00b1\u200910%. Exploratory clinical measures did not change significantly between baseline and final follow-up. Bilateral putaminal neurotrophic gene therapy delivered with real-time image guidance was well tolerated over 5\u2009years, without protocol-defined stopping events. \u00a9 2026 The Author(s).

Neuropsychiatric adverse events (AEs) have been reported in both clinical trials and real-world studies, with some real-world cohorts suggesting higher rates among patients with prior hallucinations or cognitive impairment. The present study aimed to determine the incidence and risk factors of neuropsychiatric AEs in a large prospective real-world cohort. We analyzed data from the DATs-PD GETM Spanish Registry, an observational, prospective, multicenter, open-label study. 214 patients treated with LDp/CDp CSI were included. Median age was 69\u2009years, and median disease duration was 12\u2009years. At baseline, 35% had cognitive impairment, 25.7% hallucinations/psychosis, and 26.2% impulse control disorders (ICDs). During follow-up after initiation (median 163\u2009days), 19.2% developed at least one neuropsychiatric AE, mostly mild-moderate, and only 2.3% required device removal. Most events occurred more than 1\u2009month after treatment initiation. In adjusted Cox, none of the evaluated variables were associated with the development of hallucinations/psychosis/confusion. The presence of ICD at baseline was associated with an increased risk of ICD-related AEs. Neuropsychiatric AEs, mainly hallucinations/psychosis, occurred in a clinically relevant proportion of patients treated with LDp/CDp CSI. However, they were generally mild-to-moderate and rarely led to treatment discontinuation. Except for ICD, baseline cognitive and psychotic features were not associated with higher incidence. These findings support its use in appropriately selected patients while highlighting the importance of individualized careful clinical monitoring.\n\nID: 42403079\nTitle: Freezing of Gait Levodopa Response Pattern in Parkinson's Disease Provides Clues to Pathophysiology.\nAbstract: Freezing of gait (FOG) is a common and enigmatic feature of Parkinson's disease (PD) because of its episodic and unpredictable nature. It is now clear that FOG is not a monolithic phenomenon but instead exhibits substantial heterogeneity across patients, suggesting the existence of subtypes. Among the heterogeneous features are levodopa response patterns and nonmotor features, cognitive impairment and anxiety/depression. It remains an open question as to whether these phenotypes are the result of different pathophysiology. In this paper, we develop the hypothesis that levodopa response patterns may identify FOG subpopulations tied to nonmotor symptoms and alterations in different neurotransmitter systems. Here, we review the levodopa response patterns of FOG seen in PD based on a rigorous levodopa challenge paradigm using a 40% higher dose of levodopa and blood levodopa levels to demonstrate that the majority of patients are either levodopa responsive (OFF-FOG) or unresponsive (ONOFF-FOG). The literature demonstrates that executive and affective changes are not universal in FOG and actually relate closely to levodopa response patterns, OFF-FOG is associated with affective disorders, and ONOFF-FOG is related to cognitive decline. In turn, OFF-FOG and affective disorders appear to be associated with brain noradrenergic degeneration, whereas ONOFF-FOG and cognitive decline are associated with cholinergic loss. These observations suggest different therapeutic targets by subtype. We suggest that levodopa challenge testing may help stratify FOG patients in trials and mechanistic studies.\n\nID: 42402641\nTitle: A data-driven framework for long-term risk stratification of advanced Parkinson's disease using PPMI.\nAbstract: Advanced Parkinson disease has prognostic and therapeutic implications, yet staging tools are qualitative and difficult to operationalize for longitudinal modelling and cross-cohort comparison. We developed a reproducible operationalization that translates the 13-item Diagnostic Criteria for Advanced Parkinson Disease questionnaire into structured variables and generates longitudinal labels capturing certainty of advanced disease. In the Parkinson's Progression Markers Initiative near-diagnosis cohort (n\u2009=\u20091,302; up to 13 years), we applied this pipeline to characterize label trajectories and face validity over time. As a proof of utility, we used baseline clinical and genetic features to forecast advanced disease at years 7-11, explicitly separating forecasting from contemporaneous staging. Using a binary long-horizon endpoint, the best year-9 model showed an area under the receiver operating characteristic curve of 0.89 (95% CI 0.81-0.97). In an independent real-world cohort with \u2265\u200911 years follow-up (n\u2009=\u200935), discrimination attenuated (0.55-0.61), consistent with dataset shift and limited event counts.\n\nID: 42401686\nTitle: Physical performance and DEXA-derived body composition in adults with Parkinson's disease participating in a community-based exercise program and community-dwelling older adults: a cross-sectional study.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder strongly associated with ageing that directly affects mobility and physical function. Although regular exercise is widely recognized as an important strategy to attenuate functional decline, limited evidence has simultaneously examined physical performance and body composition assessed by dual-energy X-ray absorptiometry (DEXA) in adults with Parkinson's disease participating in community-based exercise programs, particularly in Latin American settings. A cross-sectional observational study was conducted. Adults with PD participating in a community-based exercise program and community-dwelling older adults were evaluated. Physical performance was assessed using gait speed, handgrip strength, the five-times chair stand test, the single-leg balance test (SLBT), the Timed Up and Go (TUG) test, the 2-minute step test, and the Short Physical Performance Battery (SPPB). Body composition and bone mineral density (BMD) were assessed using DEXA. Propensity score matching was applied using body mass index (BMI) and sex. Descriptive statistics, Spearman correlations, and multiple linear regression models were used for data analysis. Adults with PD showed significantly lower physical performance than community-dwelling older adults, with gait speed exhibiting the largest between-group difference. In the present model, Parkinson's disease status was the strongest negative predictor of gait speed, whereas muscle strength and functional endurance were positively associated with locomotor performance. DEXA-derived lean mass was not independently associated with gait speed. Within the present sample, adults with PD participating in a community-based exercise program exhibited lower physical performance than community-dwelling older adults. Parkinson's disease status emerged as the strongest predictor of gait speed, whereas muscle strength and functional endurance were positively associated with mobility performance.\n\nID: 42401608\nTitle: Multimodal fusion of handwriting images and kinematic features for Parkinson disease detection.\nAbstract: Parkinson's disease (PD) affects fine motor control and produces measurable abnormalities in handwriting and drawing. This study proposes a rigorously evaluated multimodal framework for PD detection that combines a Vision Transformer (ViT) for spiral and meander image analysis with an XGBoost classifier operating on 54 carefully engineered kinematic features extracted from multichannel handwriting signals. To assess how multimodal integration should be performed, both intermediate feature-level fusion and late decision-level fusion were evaluated under a strict 5-fold subject-wise cross-validation protocol, with supplementary sample-level analysis, on the NewHandPD dataset. The visual stream consistently outperformed the acquisition stream as a single modality, while both fusion strategies improved performance by exploiting complementary spatial (visual) and motor information. Intermediate fusion achieved the highest apparent discriminative performance, reaching 97.7% accuracy on spiral drawings and 98.5% accuracy on meander drawings, whereas late fusion provided more interpretable and modular behavior, with best subject-level results of 93.94% accuracy and AUC\u2009=\u20090.9687 for spiral, and 92.42% accuracy with AUC\u2009=\u20090.9770 for meander. These findings suggest that multimodal handwriting analysis can be an effective approach for Parkinson's disease detection on the NewHandPD dataset, although further validation on larger and independent cohorts is required.\n\nID: 42401195\nTitle: Striatal remodeling in Parkinson disease.\nAbstract: \n\nID: 42400678\nTitle: Brain-muscle axis regulation of neuroinflammation and sarcopenia in Parkinson's disease: the bridging role of lactylation.\nAbstract: Sarcopenia is a common and often overlooked nonmotor symptom of Parkinson's disease (PD), significantly increasing the risk of falls and exacerbating the disease burden. Increasing evidence suggests that PD is not merely a neurodegenerative disease confined to the central nervous system (CNS) but also involves significant systemic metabolic disturbances and peripheral tissue dysfunction, indicating a systemic pathological character. In recent years, epigenetic modifications have gradually become an important perspective for understanding the inflammatory progression of PD. Lactate is no longer simply considered the end product of glycolysis, but can regulate gene transcription and protein function through protein lactylation. This paper systematically proposes that lactylation is a key molecular bridge between neuroinflammation and sarcopenia in PD. We searched literature from the PubMed database from 2010 to 2026, screened qualified English articles, and integrated the latest research advances in neuroimmunology, skeletal muscle biology, and metabolic epigenetics. In PD, microglia epigenetic modifications and metabolic reprogramming lead to lactate accumulation, which may drive a persistent neuroinflammatory response through lactate modification. Simultaneously, chronic inflammation and metabolic abnormalities can propagate along the brain-muscle axis, promoting skeletal muscle protein metabolic imbalance and accelerating the development of sarcopenia. Based on this, this paper systematically proposes that lactylation is a key molecular bridge between neuroinflammation and sarcopenia in PD. Combining the latest research advances in neuroimmunology, skeletal muscle biology, and metabolic epigenetics, this paper elucidates the potential mechanisms by which abnormal lactate metabolism and lactylation play a role in altered glial cell inflammatory phenotypes and skeletal muscle homeostasis imbalances. Furthermore, in conjunction with exercise intervention studies, this paper explores how lactylation, as a key regulatory molecule, can achieve bidirectional improvement in CNS inflammation and peripheral muscle function, providing a new theoretical basis for systemic intervention strategies for PD.\n\nID: 42400386\nTitle: Sequential pathway analysis of sex differences in deep brain stimulation for Parkinson's disease.\nAbstract: ObjectivesDeep brain stimulation (DBS) is a well-established treatment for Parkinson's disease (PD). Despite its proven efficacy, women are less likely to receive DBS. This study examined sex differences across the multistage clinical pathway to identify stage-specific factors contributing to disparities in utilization.DesignRetrospective cohort study using longitudinal clinical data from a single, high-volume neurological care center.MethodsData were drawn from 4,308 patients with PD treated between 2012 and 2024. Progression through the DBS pathway was modeled as four conditional stages: (S1) referral, (S2) multidisciplinary evaluation among those referred, (S3) recommendation among those evaluated, and (S4) DBS surgery among those recommended. Stage-specific Firth penalized logistic regression models were used to estimate sex differences while adjusting for demographic and clinical characteristics, including age, race, comorbidities, marital status, levodopa use, and tremor status. Sex-by-predictor interactions were assessed to identify differential effects across stages.ResultsAmong the cohort (2,866 males, 1,442 females), 186 (4.3%) received a referral for evaluation; 180 (97%) received an evaluation; and 159 (88%) received DBS. Adjusting only for sex, compared to males, females were less likely to be referred (OR=0.97, CI=0.71, 1.32), evaluated given referral (OR=0.88, CI=0.1, 5.17), and receive DBS given recommendation (OR=0.61, CI=0.17, 2.38), but more likely to receive a recommendation after evaluation (OR = 1.55, CI = 0.59-4.70). Sex-Predictors odds ratios differed [male- S1: age (OR=0.95, CI=0.93, 0.97), comorbidities (OR=1.19, CI=1.00, 1.41); S2: comorbidities (OR=0.51, CI=0.20, 0.87); S3: age (OR=0.91, CI=0.84, 0.97), non-white (OR=0.29, CI=0.09, 0.88), comorbidities (OR=1.90, CI=1.09, 3.73); S4: non-white (OR=0.15, CI=0.02, 0.91); [females- S1: unmarried (OR=0.71, CI=0.38, 0.92); S2: levodopa (OR=1.24, CI=1.06, 1.90); S3: non-white (OR=0.01, CI=0.00, 0.31); S4: tremors (OR=1.55, CI=1.04, 1.87)].ConclusionStage-specific regression showed that differential characteristics were associated with sex disparities in DBS utilization, highlighting potential targets for equity interventions. Parkinson\u2019s disease (PD) is a condition that affects movement and can make everyday activities difficult. For some people, a treatment called deep brain stimulation (DBS) can greatly improve symptoms when medications no longer provide symptom relief. DBS is a type of brain surgery that helps control movement problems such as tremors and stiffness. Even though DBS is effective, women are less likely than men to undergo this treatment. This study examined why sex differences DBS receipt occur by analyzing data from over 4,000 patients with PD who received care at a specialized neurological center. Following patients through four key steps: being referred for DBS, completing a detailed evaluation, being recommended for surgery, and ultimately receiving the procedure. This analysis showed that differences between men and women occured at multiple points along this pathway. For example, women were less likely to be referred for evaluation, and social factors such as marital status appeared to play a role. At later stages, clinical factors such as medication use and symptom type influenced whether patients moved forward with surgery, and these factors affected men and women differently. Overall, these findings suggest that unequal access to DBS is not caused by a single issue but instead resulted from a combination of social, clinical, and healthcare system factors. Understanding where these differences occur can help doctors and health systems design targeted strategies to ensure that all patients who could benefit from DBS have an equal opportunity to receive it.\n\nID: 42400323\nTitle: A PARK9 iPSC-Derived Dopaminergic Neuron Model Enables Drug Screening Targeting Autophagy-Lysosome Pathway Dysfunction in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disease characterized by dopaminergic neuronal degeneration in the substantia nigra, in which lysosomal dysfunction and impaired autophagy-lysosome pathway activity are increasingly recognized as important pathogenic mechanisms. However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes.\n\nID: 42400317\nTitle: Topography of Regional Cerebral GABAA Receptor Availability in Parkinson's Disease Patients With Freezing of Gait.\nAbstract: We aimed to explore the relationship between regional gamma-aminobutyric acid (GABAA) receptor availability, measured with [11C]-flumazenil brain positron emission tomography (PET) and freezing of gait in patients with Parkinson's disease. Freezing of gait is a significant mobility impairment with limited effectiveness to L-DOPA in advancing disease implying a role for other neurotransmitters, such as GABA. Imaging studies using [11C]-flumazenil PET and magnetic resonance imaging (MRI) were conducted in 33 patients with Parkinson's disease (9F/24M; age 68.34\u2009\u00b1\u20096.38, disease duration 8.03\u2009\u00b1\u20094.73, motor Movement Disorders Society-revised Unified Parkinson's Disease Rating Scale (MDS-UPDRS) scores 44.01\u2009\u00b1\u200914.85). Patients were classified into two groups: \"freezers\" (n\u2009=\u20098) and \"nonfreezers\" (n\u2009=\u200925), based on the MDS-UPDRS Part III off state examination. Whole brain voxel-based t-tests group comparisons were performed using SPM12. Reduced GABAA binding was observed in the cerebellum vermis, esp. vermis lobule VI, left posterior cingulum, posterior parahippocampal gyrus/fimbriae, medial occipital-temporal gyrus and the right gyrus rectus, right anterior cingulum, and adjacent right superior frontal gyrus that demonstrated significantly reduced GABAA receptor availability in the individuals with freezing as compared to those without. In addition, reductions were also seen in the left posterior putamen and pallidum. Findings may augur a role for GABAA inverse agonists for novel investigation of FOG treatment in Parkinson's disease.\n\nID: 42400260\nTitle: Vitamin B6 produced by gut microbiome regulates host behavioral phenotypes through dopaminergic metabolism.\nAbstract: The gut microbiome modulates host neuropathology, but the mechanisms linking specific microbial genes and metabolites to host phenotypes remain poorly defined. Here, we identify microbiome-derived vitamin B6 (VB6) and its biosynthesis gene as key regulators of host dopaminergic homeostasis. Metagenomic analysis of fecal samples from Parkinson's disease (PD) patients revealed enrichment of biosynthetic pathways for pyridoxal-5'-phosphate (PLP), the active form of VB6, and tyrosine decarboxylase genes. Using E. coli-C. elegans symbiotic models, we demonstrate that the bacterial pdxJ gene, encoding a key enzyme in de novo VB6 synthesis, is essential in regulating host dopaminergic homeostasis. Colonization with pdxJ-deficient bacteria led to reduced host VB6 and dopamine levels, reduced dopaminergic enzyme activity, and altered motor behavior, which were all rescued by VB6 supplementation. In PD-relevant C. elegans models, bacterial PLP biosynthesis modulated \u03b1-synuclein aggregation and behavioral deficits associated with human LRRK2 mutations. In mice, colonization with pdxJ-deficient bacteria reduced serum VB6 levels, decreased tyrosine hydroxylase staining in the substantia nigra, and impaired motor coordination, which were rescued by VB6 supplementation. Overall, our results define a bacterial pdxJ-PLP-dopamine axis that links gut microbial metabolism to host dopaminergic phenotypes and suggest bacterial VB6 biosynthesis as a potential modifier of PD risk and a context-dependent therapeutic target.\n\nID: 42399458\nTitle: Limb apraxia in Parkinson's disease and atypical parkinsonian syndromes: a systematic review.\nAbstract: Evidence regarding the clinical manifestations, disease-specific profiles and diagnostic significance of limb apraxia in Parkinson's disease and Atypical Parkinsonian Syndromes (APS) is limited. The present systematic review aims to consolidate current knowledge on limb apraxia across neurodegenerative disorders, including Parkinson's disease (PD), corticobasal syndrome (CBS), Progressive Supranuclear Palsy (PSP) and Multiple System Atrophy (MSA). A systematic literature review was conducted in accordance with PRISMA guidelines. Studies were included if they enrolled\u2009\u2265\u200910 patients in at least one of the patient groups and\u2009\u2265\u200910 control subjects with quantitative data on apraxic deficits. Risk of bias assessment was assessed. Twenty-two studies met inclusion criteria (PD n\u2009=\u200911; CBS n\u2009=\u200910; PSP n\u2009=\u20097; MSA n\u2009=\u20093). Across PD and APS, praxis assessment primarily involved gesture imitation, pantomime, action sequencing, actual tool use and measures of fine motor coordination. CBS demonstrated the most severe/widespread apraxic impairment, affecting both meaningless and meaningful (transitive and intransitive) gestures, as well as action sequencing and fine motor control. In PD, apraxic deficits were generally milder but shared overlapping features with CBS. Direct comparative studies between PD and CBS remain scarce. PSP was characterized by less frequent and predominantly sequence-related impairments, whereas findings in MSA were heterogeneous and less pronounced. Limb apraxia phenotypes differ across PD, CBS, PSP and MSA and may contribute to their differential diagnosis. Future research should adopt standardized, multimodal praxis assessment protocols in larger cohorts including all major neurodegenerative parkinsonian disorders, to facilitate the direct comparison of limb apraxia across these diseases.\n\nID: 42397913\nTitle: Distinct contributions of two subpopulations of subthalamic neurons to levodopa-induced dyskinesia.\nAbstract: The subthalamic nucleus (STN) is a prominent target for deep-brain stimulation (DBS) in the treatment of levodopa-induced dyskinesia (LID), a common motor complication of Parkinson's disease. However, the precise impact of STN-DBS on LID remains unclear. Here, we investigated the functional roles of two distinct neuronal populations within the STN in regulating LID. In a mouse model of LID, STN neurons projecting to the entopeduncular nucleus (EP) exhibited a U-shaped activation pattern, whereas those projecting to the tegmental reticular nucleus (RtTg) displayed a predominantly inhibitory response. Activation of EP-projecting STN neurons alleviated dyskinesia but worsened hypokinesia in the parkinsonian state. Activation of RtTg-projecting STN neurons alone did not induce hyperkinetic characteristics, except when combined with levodopa. These findings reveal two anatomically and functionally distinct populations of STN neurons involved in LID regulation, offering insights into the circuitry underlying STN-DBS.\n\nID: 42397272\nTitle: No Difference in Complications or Reoperation Rates Between Laminoplasty Versus Laminectomy and Fusion for Cervical Myelopathy in Patients With Parkinson's Disease.\nAbstract: A retrospective database study. To compare postoperative complications and reoperation rates between posterior cervical laminectomy and fusion (LF) and laminoplasty (LP) in myelopathy patients with concomitant Parkinson disease (PD). LF and LP are both widely accepted treatments for cervical spondylotic myelopathy (CSM), although the impact of coexisting Parkinson disease on outcomes is unclear. Given the neurodegenerative nature of PD, there is concern for development of kyphosis after laminoplasty due to muscle weakness and lack of coordination. CSM patients with a coexisting diagnosis of PD who underwent primary LF or LP were identified using International Classification of Diseases (ICD) diagnosis codes and current procedural terminology (CPT) codes in the PearlDiver database. Patients were excluded for prior cervical surgery, trauma, tumor, infection, deformity, and anterior or staged procedures. Postoperative complications, including infection, transfusion requirement, kyphosis, and pseudarthrosis, were evaluated and compared between groups along with reoperation rates at 10 years. Statistical significance was assessed by \u03c72, Fisher exact, and t tests as appropriate. A total of 1117 LF and 169 LP patients met inclusion criteria. The median age range was 70-79 years for both groups, and the majority were of moderate risk on Charlson Comorbidity Index. Complication rates were low and similar between groups. No difference in postoperative cervical kyphosis was observed. At 10 years postoperatively, 1.78% of LP patients and 3.85% of LF patients required additional cervical surgery, although this was not statistically significant (P=0.07). Complications and reoperation rates after laminectomy and fusion and laminoplasty in CSM patients with Parkinson disease were relatively low. Reoperation rates were similar between groups with a trend towards lower rates in laminoplasty, indicating that neurodegenerative disorders such as Parkinson disease do not always necessitate fusion. Level III.\n\nID: 42394039\nTitle: Feature Reduction or Sample Reduction? A Stability Analysis of Parkinson's Disease Clustering.\nAbstract: Although clustering is widely used to explore phenotypic heterogeneity in Parkinson's disease (PD), reported subtype solutions often show limited reproducibility. We investigated whether reducing the number of features or samples in a typical clinical PD dataset more strongly affects clustering stability. We used baseline PD data from the Parkinson's Progression Markers Initiative. We applied K-means, Gaussian mixture models (GMM), and DBSCAN under systematic feature and sample reduction (40 %, 60 %, 80 %, and 100 %). We assessed cluster stability using the Adjusted Rand Index (ARI) relative to feature-matched reference solutions and the pairwise ARI across repeated runs. Sample reduction had the clearest effect on agreement with the reference solution across methods, whereas feature reduction mainly affected run-to-run reproducibility. K-means was the most robust method. Feature reduction lowered reproducibility in GMM, and changes in noise assignment affected DBSCAN. Therefore, reference-solution kstability may depend more on cohort size than features.\n\nID: 42393412\nTitle: Cardiovascular pharmacology of dopaminergic agents in humans: a review.\nAbstract: To\u00a0review the cardiovascular effects of pharmacologic dopamine receptor modulation in humans, organized by receptor subtype. Narrative review of human pharmacological, genetic, and clinical evidence linking dopamine receptor agonism and antagonism to blood pressure and heart rate changes in healthy volunteers and in patients with Parkinson disease, autonomic failure, psychiatric disorders, and selected cardiovascular conditions. Dopaminergic receptor agonism generally lowers blood pressure, with the magnitude of hypotension tracking with intrinsic activity: full orthosteric agonists (bromocriptine, ropirinole, apomorphine) carry the highest risk of orthostatic hypotension, and\u00a0partial agonists (tavapadon) produce attenuated but clinically relevant hypotension. Dopamine D3-preferring agents (PF-592379, mesdopetam, cariprazine) have neutral cardiovascular effects in short-term trials. Levodopa-induced orthostatic hypotension arises from at least five converging mechanisms whose clinical impact is amplified by underlying neurogenic orthostatic hypotension. A notable exception is mevidalen, a centrally acting dopamine D1 positive allosteric modulator that paradoxically raises blood pressure. Despite murine knockout models consistently predicting that dopamine receptor deletion produces hypertension, pharmacological antagonism in humans does not reliably raise blood pressure: dopamine D1, D2, and D3 antagonists show largely neutral cardiovascular profiles, while antipsychotic-associated orthostatic hypotension is driven primarily by \u03b11-adrenergic blockade. The cardiovascular response to dopaminergic agents depends on receptor selectivity, intrinsic activity, and baroreflex integrity. The discrepancy between murine-knockout-predicted hypertension and human pharmacological neutrality with antagonists, and the hypertensive effects of dopamine D1 positive allosteric modulators, represent key unresolved questions.\n\nID: 42393258\nTitle: Patterns of spontaneous saliva swallowings during awake and sleep states in Parkinson's disease.\nAbstract: This study aimed to evaluate spontaneous swallowing frequency (SS-FR) and type of swallowing during awake and sleep states in patients with Parkinson's Disease (PD), using polygraphic recordings to identify possible associations with disease severity. A total of 27 PD patients (19 male, 8 female) and 22 age-matched healthy controls were included. All participants underwent whole-night one-hour polygraphic monitoring, and SS-FR and type of swallowing were analyzed during both wakefulness and sleep stages. Clinical characteristics, disease severity (Hoehn and Yahr staging), and motor symptoms (Unified Parkinson's Disease Rating Scale) were assessed. SS-FR was significantly lower in PD patients compared to controls, both during wakefulness and especially during sleep. In PD patients, SS-FR during wakefulness was positively correlated with Hoehn and Yahr stage and motor symptom scores. The presence of dysphagia was more common in patients with markedly reduced SS-FR, indicating its potential role as a non-invasive marker for swallowing impairment. Salvo swallowing was observed in 4.5% (n\u2009=\u20091) of controls and 40.7% (n\u2009=\u200911) of patients with PD (p\u2009=\u20090.003). SS-FR is significantly altered in PD, with reductions during both awake and sleep states reflecting disease severity. SS-FR measurement through polygraphic recordings may have potential as a non-invasive marker for early detection of swallowing disorders and progression in PD.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Although 10%-15% of PD cases are due to familial mutations, the remaining cases are sporadic, often linked to various factors, like pesticides and metals. For example, rotenone and dopamine are known to be involved in PD pathology and are suggested to cause changes in \u03b1-Syn protein homeostasis, although the mechanism by which they influence \u03b1-Syn and cellular toxicity is largely unknown. In this work, we demonstrate that both dopamine and rotenone promote the LLPS of \u03b1-Syn. Although rotenone promotes the liquid-to-solid transition almost instantaneously, dopamine, however, maintains a liquid state for a long time and rather delays the solidification process, unlike \u03b1-Syn alone. Similarly, exposure to both toxicants resulted in faster LLPS in SH-SY5Y cells. Interestingly, irrespective of their impact on material properties, rotenone promotes the faster formation of oligomers and amyloid fibrils, while dopamine exhibits oligomer formation and delayed fibrillation, both of which result in higher cytotoxicity.

Although \"Zero Hallucinated Moneyshot Quotes\" is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n### [CLAIM EVALUATED AND ANSWER TO USER]\nDoes long-term microplastic or bisphenol exposure act as a catalyst for alpha-synuclein aggregation in Parkinson's disease by disrupting lysosomal membrane permeabilization?\n\nThe provided literature confirms that exposure to microplastics (MPs/NPs) and bisphenol compounds (BPA/BHPF) independently and synergistically disrupts lysosomal integrity and proteostasis, thereby facilitating alpha-synuclein aggregation in the context of Parkinson's Disease (PD). Evidence indicates that these pollutants disrupt the autophagy-lysosome pathway, induce lysosomal membrane permeabilization (LMP), and trigger oxidative stress, which collectively converge on the pathological accumulation of alpha-synuclein.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nEnvironmental pollutants, specifically micro/nanoplastics and bisphenols, modulate the pathogenesis of Parkinson's Disease. Through the disruption of lysosomal acidification and the subsequent induction of lysosomal membrane permeabilization (LMP), these agents impair the autophagic-lysosomal pathway's ability to clear alpha-synuclein, thereby accelerating disease-associated neurodegeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe neurodegenerative trajectory of Parkinson's Disease is increasingly understood as a convergence of genetic vulnerability and environmental insult. The provided literature delineates a clear mechanistic bridge between environmental plastic/phenolic pollutants and PD pathology. Microplastics and nanoplastics penetrate the central nervous system, where they actively interfere with the lysosome's structural and functional capacity. Lysosomal membrane permeabilization, often triggered by zinc-mediated stress or direct surface binding, prevents the orderly degradation of alpha-synuclein, the hallmark protein of Lewy bodies. Similarly, bisphenol compounds initiate oxidative and endoplasmic reticulum stress, which suppresses lysosomal autophagy and exacerbates the aggregation of misfolded proteins.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics can cross the blood-brain barrier via multiple routes, including olfactory and circumventricular pathways, particularly when barrier integrity is compromised.\n*   The initiation of alpha-synuclein aggregation predominantly occurs at the lysosomal membrane surface.\n*   Zinc homeostasis serves as a vital regulatory nexus where mitochondrial dysfunction links to lysosomal failure via intracellular zinc accumulation.\n*   Polystyrene nanoplastics have been observed to trigger microglial M1 activation, which propagates neuroinflammation through a feedforward loop.\n*   There exists a \"charge-specific injury\" paradigm where surface properties of nanoplastics determine whether they trigger hepatocyte ferroptosis or endothelial senescence.\n*   Taurine depletion is a predictive biomarker for microplastic-induced cognitive decline and synaptic loss.\n*   GCase enzyme activity is a genetic convergence point for lysosomal degradation failure in both GBA1-mutant and environmentally stressed PD models.\n*   A \"kidney-brain axis\" in PD pathogenesis suggests that peripheral alpha-synuclein aggregates in renal tissues may precede systemic spread to the central nervous system.\n*   Small EPs or \"SECmeres\" (sub-50nm particles) in blood are emerging as potentially superior biomarkers compared to classical extracellular vesicles for brain-specific signatures.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

It is the first neural system exposed to food contaminants (FCs)-a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or environmental contamination. Emerging evidence suggests that FCs may initiate or amplify neurodegenerative processes, yet their effects on the ENS and their impact in gut-to-brain communication remain insufficiently characterized. This systematic review synthesizes current evidence on FCs-induced effects on the ENS and its involvement in mediating neurotoxicity from dietary toxicants exposure. Following PRISMA guidelines, 67 studies were included pertaining to cellular or mammalian experimental models exposed to FCs via enteral routes, reporting ENS-related outcomes or studying vagal involvement in modulating FC toxicity. The main FCs evaluated were pesticides, toxins, bisphenols, acrylamide, manganese, and micro-/nanoplastics. Across studies, FCs consistently induced neurochemical remodeling of the ENS, activation of enteric glia, often coupled with intestinal alterations. Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain. Vagotomy models confirmed that disrupting ENS-CNS communication attenuates FC-related central neurotoxicity, supporting the involvement of food toxicants in gut-to-brain propagation of neurotoxic signals. These findings support the body-first hypothesis of PD and position the ENS as a critical, yet underinvestigated interface in exposome-related neurotoxicology. The review highlights research gaps and the need for improved models and long-term, low-dose studies reflecting realistic FC exposure."

This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

Here, we employed high-resolution untargeted lipidomics to map brain lipid perturbations in Drosophila melanogaster chronically exposed to polystyrene nanoplastics (PS- NPs). PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids, notably cardiolipins and phosphatidylethanolamines, accompanied by increased diacylglycerols/triacylglycerols and monounsaturated fatty acids and by lipid droplet expansion. Guided by these lipidomic signatures, targeted biochemical assays demonstrated depolarized mitochondrial membrane potential, elevated mitochondrial reactive-oxygen species, inhibition of respiratory-chain complexes I and IV, and a shift in NAD(H) and NADP(H) redox couples toward a reduced state and increasing lipid peroxidation. This redox imbalance was accompanied by decreased tyrosine-hydroxylase expression, dopamine depletion, and impaired locomotor behavior, hallmarks of Parkinson's disease (PD)-like neurodegeneration. Dopaminergic neurochemistry was impaired (tyrosine hydroxylase and dopamine decreased), with concomitant reduction of GABA, and locomotor and circadian deficits emerged. Remarkably, co-treatment with the antioxidant N-acetylcysteine (NAC) restored mitochondrial membrane potential, reduced mitochondrial ROS and lipid peroxidation, normalized neutral lipid and MUFA accumulation, and rescued neurotransmitter levels and behavior. Stable-isotope tracing confirmed disrupted TCA cycle flux after NPs exposure that was rescued by NAC. Collectively, these findings reveal lipidomic remodeling as a critical link between environmental NPs exposure and PD-like pathology, highlighting mitochondrial redox-lipid interactions as early determinants and support redox-directed interventions to mitigate risk."

Here, we use functional proteomics, single-particle cryo-EM, electrophysiology, and in\u00a0vivo imaging to unravel a key biological function of human lysosome-associated membrane proteins (LAMP-1 and LAMP-2) in regulating lysosomal pH homeostasis. Despite being widely used as a lysosomal marker, the physiological functions of the LAMP proteins have long been overlooked. We show that LAMP-1 and LAMP-2 directly interact with and inhibit the activity of the lysosomal cation channel TMEM175, a key player in lysosomal pH homeostasis implicated in Parkinson's disease. This LAMP inhibition mitigates the proton conduction of TMEM175 and facilitates lysosomal acidification to a lower pH environment crucial for optimal hydrolase activity. Disrupting the LAMP-TMEM175 interaction alkalinizes the lysosomal pH and compromises the lysosomal hydrolytic function. In light of the ever-increasing importance of lysosomes to cellular physiology and diseases, our data have widespread implications for lysosomal biology."

A reduced number of intraneuronal lysosomes, decreased levels of lysosomal-associated proteins and accumulation of undegraded autophagosomes (AP) are observed in PD-derived samples, including fibroblasts, induced pluripotent stem cell-derived dopaminergic neurons, and post-mortem brain tissue. Mechanistic studies in toxic and genetic rodent PD models attribute PD-related lysosomal breakdown to abnormal lysosomal membrane permeabilization (LMP). However, the molecular mechanisms underlying PD-linked LMP and subsequent lysosomal defects remain virtually unknown, thereby precluding their potential therapeutic targeting. Here we show that the pro-apoptotic protein BAX (BCL2-associated X protein), which permeabilizes mitochondrial membranes in PD models and is activated in PD patients, translocates and internalizes into lysosomal membranes early following treatment with the parkinsonian neurotoxin MPTP, both in vitro and in vivo, within a time-frame correlating with LMP, lysosomal disruption, and autophagosome accumulation and preceding mitochondrial permeabilization and dopaminergic neurodegeneration. Supporting a direct permeabilizing effect of BAX on lysosomal membranes, recombinant BAX is able to induce LMP in purified mouse brain lysosomes and the latter can be prevented by pharmacological blockade of BAX channel activity. Furthermore, pharmacological BAX channel inhibition is able to prevent LMP, restore lysosomal levels, reverse AP accumulation, and attenuate mitochondrial permeabilization and overall nigrostriatal degeneration caused by MPTP, both in vitro and in vivo. Overall, our results reveal that PD-linked lysosomal impairment relies on BAX-induced LMP, and point to small molecules able to block BAX channel activity as potentially beneficial to attenuate both lysosomal defects and neurodegeneration occurring in PD."

Recent studies have shown that extracellular \u03b1Syn aggregates taken up by the endosomal-lysosomal system can rupture the lysosomal vesicular membrane; however, it remains unclear whether lysosomal rupture leads to the transmission of \u03b1Syn aggregation. Here, we applied cell-based \u03b1Syn propagation models to show that ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy, i.e., selective autophagy of damaged lysosomes. \u03b1Syn aggregates accumulated predominantly in lysosomes, causing their rupture, and seeded the aggregation of endogenous \u03b1Syn, initially around damaged lysosomes. Exogenous \u03b1Syn aggregates induced the accumulation of LC3 on lysosomes. This LC3 accumulation was not observed in cells in which a key regulator of autophagy, RB1CC1/FIP200, was knocked out and was confirmed as lysophagy by transmission electron microscopy. Importantly, RB1CC1/FIP200-deficient cells treated with \u03b1Syn aggregates had increased numbers of ruptured lysosomes and enhanced propagation of \u03b1Syn aggregation. Furthermore, various types of lysosomal damage induced using lysosomotropic reagents, depletion of lysosomal enzymes, or more toxic species of \u03b1Syn fibrils also exacerbated the propagation of \u03b1Syn aggregation, and impaired lysophagy and lysosomal membrane damage synergistically enhanced propagation. These results indicate that lysophagy prevents exogenous \u03b1Syn aggregates from escaping the endosomal-lysosomal system and transmitting aggregation to endogenous cytosolic \u03b1Syn via ruptured lysosomal vesicles. Our findings suggest that the progression and severity of synucleinopathies are associated with damage to lysosomal membranes and impaired lysophagy."

Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons. We found that the initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44). Remarkably, we demonstrate that WDR44 knockdown markedly reduced de novo \u03b1-SYN aggregation in both neuronal cultures and in vivo, whereas WDR44 overexpression enhances \u03b1-SYN aggregation in PD patient-derived iPSC neurons. Consistent with its potential pathogenic involvement, WDR44 aberrantly accumulates in vivo and in the brains of PD patients, where it colocalizes with LB inclusions. Finally, we show that lysosome-associated \u03b1-SYN aggregates compromised lysosomal structure and function, leading to neuronal impairment, a phenotype worsened by WDR44 overexpression, linking early aggregation events to downstream toxicity. Together, these findings reveal the earliest dynamic stages of \u03b1-SYN oligomerization in living neurons and identify the WDR44-\u03b1-SYN interaction as a promising therapeutic target for reducing \u03b1-SYN pathology and enabling early intervention in PD."

Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs.

Hence, the present study was conducted to decipher the neurodegenerative potential of BPA in inducing Parkinson's disease like phenotypes in zebrafish. Zebrafish were subjected to chronic waterborne exposure to BPA for 56 days. Locomotor activities and neurobehavioral response were assessed by the NTDT (novel tank diving test), OFT (open field test), and LDPT (light-dark preference test). The oxidative stress markers and histopathological observation for pyknosis and chromatin condensation were carried out. Immunohistochemistry for activated caspase-3 and targeted proteins expression study was performed. The basic findings reveal that chronic BPA exposure significantly induces locomotor dysfunction through a significant decline in mean velocity and total distance traveled. As a measure of pyknosis and chromatin condensation, pyknotic and Hoechst positive neurons in telencephalon and diencephalon significantly increased by BPA exposure. A higher concentration of BPA adversely affects the neurobehavioral response, antioxidant status, and neuromorphology in zebrafish. Parkinson-relevant targeted protein expression viz. alpha-synuclein and LRRK2, were significantly upregulated, whereas tyrosine hydroxylase, NeuN, and Nurr1 were significantly downregulated in the zebrafish brain. As an indicator of cell death by apoptosis, the expression of activated caspase-3 was significantly increased in the BPA-exposed zebrafish brain. These basic results of the current study indicate that chronic waterborne exposure to BPA induces neuropathological manifestation leading to the development of motor dysfunction and Parkinsonism-like neurodegenerative phenotypes in zebrafish."

This pH homeostasis is a consequence of proton influx produced by a V-type H+-translocating ATPase (V-ATPase) and rapid proton efflux through an unidentified \"leak\" pathway. By performing a candidate expression screening, we discovered that the TMEM175 gene encodes a proton-activated, proton-selective channel (LyPAP) that is required for lysosomal H+ \"leak\" currents. The activity of LyPAP is most active when lysosomes are hyper-acidified, and cells lacking TMEM175 exhibit lysosomal hyper-acidification and impaired proteolytic degradation, both of which can be restored by optimizing lysosomal pH using pharmacological agents. Variants of TMEM175 that are associated with susceptibility to Parkinson disease (PD) cause a reduction in TMEM175-dependent LyPAP currents and lysosomal hyper-acidification.

Associated with oxidative stress, there was a reduction of acetylcholinesterase activity and a reduction of dopamine levels, which are related to the decreased locomotion activity as observed in negative geotaxis, open field and equilibrium behaviors in group exposed to 1\u00a0mM of BPA. Oxidative stress also impaired mitochondrial and cellular metabolic activity in the head causing an increase in the mortality of flies exposed to both BPA concentrations.

However, how lysosomes participate in the spreading of \u03b1-syn aggregates is unclear. Here, by using super-resolution (SR) and electron microscopy (EM), we find that \u03b1-syn fibrils affect the morphology of lysosomes and impair their function in neuronal cells. In addition, we demonstrate that \u03b1-syn fibrils induce peripheral redistribution of lysosomes, likely mediated by transcription factor EB (TFEB), increasing the efficiency of \u03b1-syn fibrils' transfer to neighboring cells. We also show that lysosomal membrane permeabilization (LMP) allows the seeding of soluble \u03b1-syn in cells that have taken up \u03b1-syn fibrils from the culture medium, and, more importantly, in healthy cells in coculture, following lysosome-mediated transfer of the fibrils. Moreover, we demonstrate that seeding occurs mainly at lysosomes in both donor and acceptor cells, after uptake of \u03b1-syn fibrils from the medium and following their transfer, respectively. Finally, by using a heterotypic coculture system, we determine the origin and nature of the lysosomes transferred between cells, and we show that donor cells bearing \u03b1-syn fibrils transfer damaged lysosomes to acceptor cells, while also receiving healthy lysosomes from them. These findings thus contribute to the elucidation of the mechanism by which \u03b1-syn fibrils spread through TNTs, while also revealing the crucial role of lysosomes, working as a Trojan horse for both seeding and propagation of disease pathology."

However, the likelihood of developing PD with inherited LRRK2 pathogenic variants differs (a phenomenon known as \"reduced penetrance\"), with factors including age and geographic region, highlighting a potential role for lifestyle and environmental factors in disease onset. To investigate this, household dust samples from four different groups of individuals were analyzed using metabolomics/exposomics and metagenomics approaches: PD+/LRRK2+ (PD patients with pathogenic LRRK2 variants; n\u00a0=\u00a011), PD-/LRRK2+ (individuals with pathogenic LRRK2 variants but without PD diagnosis; n\u00a0=\u00a08), iPD (PD of unknown cause; n\u00a0=\u00a011), and a matched, healthy control group (n\u00a0=\u00a011). The dust was complemented with metabolomics and lipidomics of matched serum samples, where available. A total of 1,003 chemicals and 163 metagenomic operational taxonomic units (mOTUs) were identified in the dust samples, of which ninety chemicals and ten mOTUs were statistically significant (ANOVA p-value\u00a0<\u00a00.05). Reduced levels of 2-benzothiazolesulfonic acid (BThSO3) were found in the PD-/LRRK2+\u00a0group compared to the PD+/LRRK2+\u00a0. Among the significant chemicals tentatively identified in dust, two are hazardous chemical replacements: Bisphenol S (BPS), and perfluorobutane sulfonic acid (PFBuS). Furthermore, various lipids were found altered in serum including different lysophosphatidylethanolamines (LPEs), and lysophosphatidylcholines (LPCs), some with higher levels in the PD+/LRRK2+\u00a0group compared to the control group. A cellular study on isogenic neurons generated from a PD+/LRRK2+\u00a0patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis. This pilot study demonstrates how non-target metabolomics/exposomics analysis of indoor dust samples complemented with metagenomics can prioritize relevant chemicals that may be potential modifiers of LRRK2 penetrance."

This study examines the physiological and neurotoxic effects of these minuscule nanoplastic particles on the nematode Caenorhabditis elegans as well as on human cells. Here, we find that 25\u00a0nm polystyrene nanoplastic particles can inhibit animal growth and movement at very low concentrations, with varying effects on their surface groups. Furthermore, these nanoplastic particles not only accumulate in the digestive tract but also penetrate further into extraintestinal tissues. Such nanoplastics significantly compromise the integrity of the intestinal barrier, leading to \"leaky gut\" conditions and cause mitochondrial fragmentation in muscles, which possibly explains the observed movement impairments. A striking discovery was that these nanoplastics exacerbate symptoms similar to those of Parkinson's disease (PD), including dopaminergic neuronal degeneration, locomotor dysfunction, and accumulation of \u03b1-Synuclein aggregates. Importantly, our study demonstrates that the detrimental effects of nanoplastics on the aggregation of \u03b1-Synuclein extend to both C. elegans and human cell models of PD. In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems. ENVIRONMENTAL IMPLICATION: The escalating prevalence of nanoplastics in the environment due to widespread plastic usage raises potential health risks. Studies conducted on C. elegans indicate that even low concentrations of 25\u00a0nm polystyrene nanoplastics can impair growth and movement. These particles accumulate in the digestive system, compromising the intestinal barrier, causing \"leaky gut\", as well as inducing Parkinson's-like symptoms. Importantly, in both C. elegans and human cell models of Parkinson's disease, such nanoplastics penetrate tissues or cells and increase \u03b1-Synuclein aggregates. This underscores the urgent need to understand the interactions of nanoplastics with biological systems and highlights potential environmental and health consequences."

Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions."

These processes lead to the formation of pathological proteins, resulting in the brain diseases called synucleinopathies, tauopathies or TDP-43 proteinopathies. There is currently growing support for the hypothesis that genetic variants explain a significant fraction of the etiology of apparently sporadic parkinsonian disorders. Genetic risk factors can be stratified according to the metabolic or structural processes that can lead to cellular disturbance;\u00a0these processes involve protein aggregation, protein and membrane trafficking, stabilization of the neurite structure, prion-like transmission of pathological proteins, ubiquitin-proteasome system balance, mitophagy, lysosome autophagy, synaptic functions, and dopamine transmission. Regarding the environmental risk factors, there are several substances that have been supposed of being a risk for the development of neurodegenerative proteinopathy and Parkinsonism, mainly the agents used in agriculture and the textile industry. The most important and most frequently studied are pesticides and trichlorethylene. Beside the globally ubiquitous substances which are supposedly neurotoxic and exposure to which can cause manifestations of Parkinsonism, there are more geographically (regionally) specific substances, which cause (or quite recently caused) the manifestation of endemically present Parkinsonism. Among ten types of endemic Parkinsonism, three of them are thought to have an environmental cause: Western Pacific Parkinsonism, Caribbean Parkinsonism, and North France cluster of atypical Parkinsonism."

We used LRRK2R1627P knock-in rats (human LRRK2-R1628P corresponds to rat LRRK2-R1627P) to investigate the R1627P mutation on function of dopaminergic neurons (DANs) and their susceptibility to the environmental toxin Lipopolysaccharide (LPS) during aging. LRRK2R1627P rats showed no significant loss of DANs, dopamine and its metabolites, or motor dysfunction; however, spontaneous exploration and olfactory discrimination reduced, and dendritic spines of DANs showed degeneration. We found decreased pThr73-Rab10 located on the trans-Golgi, disrupted Golgi structure and lipofuscin accumulation in aged LRRK2R1627P rat DANs, and the protein related to trans-Golgi complex and regulating lysosome function were significantly reduced. Although the neuroinflammation of brain was not obvious in the aging process, we confirmed a decrease in the ratio of CD4+/CD8+ and B cells, an increase in inflammatory factors (TLR4, NFKB, TNF-\u03b1) in the periphery. Furthermore, we demonstrated that the R1627P mutation caused the abnormal accumulation of \u03b1-Syn in the aged rat intestine. LPS exacerbated pathological \u03b1-Syn aggregation in the small intestine of LRRK2 transgenic rats and spread to the brain via the gut-brain axis. This led to microgliosis in the substantia nigra, creating a pro-inflammatory environment and inducing DANs degeneration. Gut-brain axis disruption may be a key determinant of progression to R1628P-PD in R1628P carriers. This insight has important clinical implications and highlights the importance of monitoring and addressing gut-brain axis integrity in individuals with LRRK2 mutations."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

Evidence demonstrates that these exogenous agents can induce lysosomal membrane permeabilization (LMP), which directly facilitates the transmission of \u03b1-synuclein aggregates.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific research confirms that environmental pollutants, including nanoplastics and endocrine-disrupting chemicals like bisphenol, disrupt cellular proteostasis. These substances promote alpha-synuclein misfolding and aggregation, partially through the impairment of lysosomal-autophagy pathways (ALP) and the induction of lysosomal membrane damage. This disruption creates a feed-forward cycle where impaired degradation increases protein toxicity and further exacerbates lysosomal fragility.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic aggregation of \u03b1-synuclein is a central feature of Parkinson's disease (PD). The recent literature establishes that exogenous environmental triggers, such as PS-NPs and BPA, initiate or amplify this pathology by compromising the integrity of the endolysosomal system. Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain. Once these particles reach the brain, they exert deleterious effects on cellular homeostasis. \n\nThe mechanism involves complex organellar stress. PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids. This mitochondrial dysfunction is intimately linked to lysosomal status. Disrupting the LAMP-TMEM175 interaction alkalinizes the lysosomal pH and compromises the lysosomal hydrolytic function. Furthermore, pharmacological BAX channel inhibition is able to prevent LMP, restore lysosomal levels, reverse AP accumulation, and attenuate mitochondrial permeabilization and overall nigrostriatal degeneration caused by MPTP. \n\nThe direct link between membrane damage and aggregation is substantiated: ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy. Thus, pollutants that provoke LMP or inhibit lysophagy serve as fundamental drivers of disease progression.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics can cross the blood-brain barrier (BBB) within 1.5 hours and induce cell-specific inflammatory responses in astrocytes and microglia.\n*   WDR44 is a newly identified adaptor protein that facilitates \u03b1-synuclein aggregation specifically at the lysosomal membrane.\n*   Anionic nanoplastics specifically interact with the non-amyloid component (NAC) domain of \u03b1-synuclein to induce fibril formation.\n*   The initiation of \u03b1-synuclein aggregation is now visualized as a dynamic, membrane-associated event rather than a purely cytosolic one.\n*   Lysophagy, the selective autophagy of ruptured lysosomes, acts as a primary cellular defense mechanism to stop the \"seeding\" of \u03b1-synuclein aggregation in the cytosol.\n*   The interaction between PS-NPs and \u03b1-synuclein changes the protein structure from an open helical state to a compact, aggregation-prone conformation.\n*   Even low-dose, long-term exposure to nanoplastics (0.1 \u03bcg/L) is sufficient to induce measurable Parkinsonian-like behaviors in experimental models.\n*   BPA and its derivatives induce neurotoxicity via multiple channels, including oxidative stress and the downregulation of tyrosine hydroxylase.\n*   The gut-brain axis is a confirmed route for the propagation of pollutant-induced proteinopathies.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Currently, there are limited opportunities for intervention. There is a lack of reliable biomarkers to identify patients with PD, which poses a challenge for clinicians. In this review, recent advances in PD biomarker research, including genomic, epigenomic, proteomic, and non-coding RNA, will be highlighted, with particular emphasis on integrating omics for precision medicine. In addition, the current understanding of PD pathogenesis will be covered, including the root cause of familial and sporadic PD, as well as other significant contributing pathogenic events such as the formation of \u03b1-synuclein aggregates, mitochondrial dysfunction, autophagy, oxidative stress, and neuroinflammation. Recent progress in proteomic biomarkers, including cerebrospinal fluid and blood biomarkers such as \u03b1-synuclein, Neurofilament-Light-Chain, and dopamine-associated proteomics, will be reviewed for their utility. Merging evidence on non-coding RNAs, including microRNAs, long non-coding RNAs, circular RNAs, and piRNAs, further supports the notion of non-coding RNAs' regulatory functions in PD pathogenesis and their potential as non-invasive biomarkers. Lastly, strategies that integrate multi-omics data through systems biology, machine learning, and artificial intelligence are presented as viable approaches to support improved patient diagnosis and stratification, as well as the identification of new drug targets for PD. However, challenges related to heterogeneity, reproducibility, and clinical translation continue to limit the implementation of multi-omics biomarkers in PD. Overall, integrative multi-omics approaches combined with advanced computational strategies may provide a more comprehensive framework for early diagnosis, patient stratification, and the development of disease-modifying therapies in PD.\n\nID: 42274838\nTitle: APOE4-Expressing Astrocytes Exhibit Parkinson's Disease-Related Pathology.\nAbstract: Parkinson's disease (PD) is characterized by motor symptoms that are mainly attributed to the progressive loss of dopaminergic neurons of the substantia nigra (SN). It is also characterized by abnormal inclusion vesicles, termed Lewy bodies (LBs), enriched with \u03b1-synuclein aggregates that may induce inflammation and neurotoxicity. The possibility that factors involved in other neurodegenerative diseases also affect PD-related pathologies, such as \u03b1-synuclein uptake, was examined. The apoe4 allele is a major genetic risk factor for Alzheimer's disease (AD) and has also been suggested to be involved in PD. Here, we examined the effects of APOE isoform expression on \u03b1-synuclein uptake and autophagy in astrocytes expressing the apoe3 or apoe4 alleles. Using multiple autophagy manipulations (EBSS, chloroquine, and rapamycin treatments), we found that \u03b1-synuclein uptake and autophagy readouts differ between APOE3 and APOE4 astrocytes, supporting a functional link between autophagy status and \u03b1-synuclein levels. Astrocytes expressing APOE4 exhibit reduced uptake of \u03b1-synuclein and reduced autophagy. Moreover, \u03b1-synuclein treatment inhibits autophagy mainly in APOE3-expressing cells. Additional experiments showed that the autophagy inhibitor chloroquine reduced \u03b1-synuclein uptake in APOE3 astrocytes but not in APOE4 astrocytes, while\u00a0the autophagy enhancer rapamycin increased \u03b1-synuclein uptake in APOE4-expressing astrocytes. In addition, we found that Toll-like receptor 2 (TLR2) levels are elevated at both the mRNA and protein levels in APOE4-expressing astrocytes, whereas \u03b1-synuclein increased only TLR2 mRNA levels in APOE3-expressing astrocytes. Using the neurotoxin 1-methyl-4-phenylpyridinium (MPP+), we found that it affects cell growth in both APOE3 and APOE4-expressing astrocytes. MPP+ treatment also reduced autophagy which was partially corrected by rapamycin. Taken together, these findings show that in astrocytes, APOE4 impairs \u03b1-synuclein uptake, which was emended by rapamycin and \u03b1-synuclein inhibits autophagy mainly in APOE3. These findings suggest that autophagy-targeting strategies can modulate astrocyte \u03b1-synuclein uptake; however, given the observed reductions in astrocyte cell number following rapamycin treatment, further optimization or examination of alternative autophagy modulators is needed.\n\nID: 42233523\nTitle: Leucine-rich repeat kinase 2 (LRRK2): balancing cellular homeostasis and Parkinson's disease (PD) pathogenesis.\nAbstract: Leucine-rich repeat kinase 2 (LRRK2) is a kinase with multi-signalling function that regulates various processes essential for neuronal and systemic physiology. It is involved in autophagy, vesicular trafficking, mitochondrial dynamics, and immune response. Pathogenic mutations of LRRK2 can significantly interfere with these physiological pathways essential for neuronal homeostasis, inducing degeneration of dopaminergic neurons-a characteristic feature of Parkinson's disease (PD). This review comprehensively summarizes the normal cellular functions of LRRK2 and the potential impact of its dysregulation on various physiological pathways, predisposing individuals to familial and sporadic PD. The mechanistic connections between LRRK2's kinase hyperactivity, disturbances in vesicular trafficking and redox status, systemic and neuronal inflammation, and metabolic disorders will be thoroughly discussed. Dysregulation of vesicular trafficking, mitochondrial redox balance, inflammatory pathways, and metabolism promotes \u03b1-synuclein accumulation and contributes to the degeneration of nigrostriatal dopaminergic neurons, a central pathological feature of PD. Understanding the physiological role of LRRK2 across neuronal and peripheral tissues uncovers its connection with multiple pathways to maintain homeostasis. Its dysfunction disseminates local stresses into broader neurodegenerative changes. LRRK2 is implicated in multiple pathways that control neuronal integrity and neurodegeneration. Therefore, therapeutic targeting of LRRK2 could potentially help in restoring physiological function and management of PD.\n\nID: 42206954\nTitle: Blm10/PA200-Activated 20S Proteasomes Promote \u03b1-Synuclein Degradation and Bypass Proteasome Inhibition in Parkinson's Disease Models.\nAbstract: Protein homeostasis is essential for maintaining normal cellular function. However, protein homeostasis efficiency declines with age, leading to the accumulation of aberrant protein structures associated with neurodegenerative diseases such as Parkinson's disease (PD). PD is characterized by the aggregation of alpha-synuclein (\u03b1Syn) into cytoplasmic inclusions. This process is accompanied by elevated phosphorylation at serine 129 (S129). The accumulation of \u03b1Syn into aggregates and their propagation disrupts key proteostasis pathways, including the ubiquitin-proteasome system (UPS) or autophagy, contributing to cellular dysfunction and neuronal death. This study identified the proteasome activator Blm10 and its human ortholog PA200 as modulators of \u03b1Syn degradation and toxicity. The conserved Blm10/PA200 protein plays a key role in regulating proteasome activity and assembly. The \u03b1Syn expression increases Blm10 protein stability through autophagy inhibition, in a manner dependent on \u03b1Syn phosphorylation at S129 in yeast. Overexpression of BLM10 or PA200 reduces \u03b1Syn aggregation and enhances \u03b1Syn turnover via activation of the 20S proteasome in yeast and mammalian cells. Blm10 and PA200-capped 20S proteasomes efficiently degrade both monomeric as well as oligomeric \u03b1Syn in\u00a0vitro. Notably, capped proteasomes retain proteolytic activities in the presence of \u03b1Syn, indicating resistance to \u03b1Syn-induced inhibition, in contrast to 20S or 26S proteasomes. These results reveal a distinct proteasome subtype that bypasses UPS impairment and restores proteolytic capacity under proteotoxic stress. Our findings establish Blm10/PA200 as critical regulators of \u03b1Syn proteostasis and highlight its protective role in maintaining protein homeostasis and cell viability under conditions of \u03b1Syn toxicity.\n\nID: 42154074\nTitle: \u03b1-Synuclein as a molecular link between Parkinson's disease and chronic kidney disease: insights into the kidney-brain axis.\nAbstract: \u03b1-synuclein (\u03b1-syn), a presynaptic protein encoded by the SNCA gene, is implicated in the pathogenesis of Parkinson's disease (PD) because of its tendency to misfold and form aggregates. Emerging evidence suggests that \u03b1-syn dysfunction may also affect peripheral organs, with chronic kidney disease (CKD) increasingly recognized as a potential comorbidity. This review critically examines current evidence on the molecular pathways linking PD and CKD through \u03b1-syn. \u03b1-Syn comprises an N-terminal lipid-binding domain, a non-amyloid component (NAC) region prone to aggregation, and a C-terminal domain that regulates conformational stability. Among the proposed mechanisms, mitochondrial dysfunction, oxidative stress, and impaired autophagy-lysosomal clearance represent the most consistently reported pathways across neuronal and renal systems, while activation of the renin-angiotensin system (RAS) has been implicated in more limited or context-dependent studies. Preclinical and limited clinical observations indicate that \u03b1-syn-associated processes may contribute to podocyte injury and fibrotic remodeling in renal tissue, whereas reduced \u03b1-syn expression has been suggested to compromise epithelial cell stability. These findings support the concept of a kidney-brain axis; however, the extent and directionality of this interaction remain incompletely defined. Novel \u03b1-syn-targeted therapies, including ENT-01, Cu(II)ATSM, ambroxol, and lipid-modulating strategies, are being investigated for their cross-organ efficacy, although most evidence currently derives from preclinical or early-phase studies. Importantly, key knowledge gaps persist, including the mechanisms underlying peripheral \u03b1-syn aggregation, the pathways of inter-organ communication, and the clinical validity of \u03b1-syn-based biomarkers. Overall, current evidence supports a potential role for \u03b1-syn as a contributing molecular link between neurodegenerative and renal dysfunction, rather than a definitive unifying mechanism, underscoring the need for integrated and evidence-driven diagnostic and therapeutic approaches.\n\nID: 42116584\nTitle: Targeting \u03b1-Synuclein: Current Strategies and Emerging Therapies for Synucleinopathies.\nAbstract: Alpha-synuclein (\u03b1-syn) is a crucial protein involved in the pathogenesis of Parkinson's Disease (PD) and other synucleinopathies. It is important with respect to neuron health, regulation of \u03b1-syn protein synthesis, and its degradation. Numerous cellular pathways implicated in the process of autophagy, chaperone, and proteolysis play a vital role in the maintenance of \u03b1-syn protein homeostasis. Autophagy dysfunction defeats \u03b1-syn protein accumulation and neuroinflammation, as present in dementia with Lewy bodies and sporadic PD. Oxidative stress is another key factor that intensifies \u03b1-syn protein misfolding and aggregation, thereby leading to neurodegeneration. Involvement in the treatment of \u03b1-syn related disorders includes passive and active immunization, inhibitors of protein aggregation, gene silencing technology, modulators of synaptic function, and target drug delivery systems. Other \u03b1-syn related therapy approaches include the development of a novel herbal formulation focusing on the gut-brain axis and interventions designed to enhance protein quality control. As clinical trials move forward, minimizing challenges related to the target involved, biomarkers, and patient stratification is crucial to decoding these therapies into effective management. These insights not only advance our understanding of \u03b1-syn biology but also highlight the urgency of early and multi-targeted therapeutic interventions.\n\nID: 42093006\nTitle: The emerging role and therapeutic targeting of autophagy-lysosome pathway in the pathogenesis of Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by dopaminergic neuron loss and the accumulation of misfolded \u03b1-synuclein, yet the underlying mechanisms remain incompletely understood. Over the past two decades, genetic discoveries have highlighted the convergence of multiple familial PD genes on the autophagy-lysosome pathway (ALP), a key cellular system responsible for the degradation and recycling of intracellular components. Recent studies have further revealed that components of the ALP not only mediate the clearance of \u03b1-synuclein aggregates but also, under certain pathological conditions, contribute to their propagation via lysosomal exocytosis or secretory autophagy. The precise functions of autophagy are highly context-dependent, with neuronal and glial cells exhibiting distinct ALP dynamics that shift with development, stress, and aging. In this review, we summarize current knowledge on the physiological regulation of autophagy in the brain and critically examine its involvement in PD pathogenesis, incorporating mechanistic insights from familial models and emerging evidence from sporadic PD. We also explore translational implications, focusing on efforts to identify ALP-related biomarkers in cerebrospinal fluid and urine, and on the therapeutic potential of modulating ALP activity. Although the causality between ALP dysfunction and PD remains elusive, mounting evidence supports its contribution to disease progression, particularly through impaired lysosomal homeostasis and disrupted intracellular trafficking. Future research should aim to define cell type-specific ALP alterations, clarify the bidirectional interactions between \u03b1-synuclein and autophagic machinery, and develop in vivo tools to monitor autophagy activity and secretory signatures. A deeper understanding of these processes will be crucial for refining PD models, discovering robust fluid biomarkers, and designing targeted therapies capable of modifying disease trajectory.\n\nID: 42081152\nTitle: Beyond Amyloids: Neuroprotective Potential of Betanin and its Derivatives Against Alpha-Synuclein Aggregates and ROS Overload in Parkinson's Disease.\nAbstract: The aggregation of alpha-synuclein (\u03b1SN) is a key pathological feature of Parkinson's disease (PD), leading to neural cell death via reactive oxygen species (ROS) overload and activation of downstream neurotoxic pathways. Betanin, a beetroot-derived small molecule, has exhibited antioxidant and neuroprotective properties. In this study, three betaxanthins-Bxn-A, Bxn-B, and Bxn-C-were chemically synthesized from betanin to enhance its therapeutic properties. Betaxanthin Bxn-A effectively reduced intracellular ROS levels without cytotoxicity, even at 500 \u00b5M. Additionally, betanin and its derivatives revealed neuroprotective effects, including significant reductions in apoptosis, preservation of mitochondrial membrane potential, modulated autophagy, and enhanced cell viability in PD-model cells. In terms of aggregation inhibition, betaxanthins Bxn-A and Bxn-B significantly reduced \u03b1SN aggregation compared to the control after 48 h of incubation. Betaxanthin Bxn-A also triggered disaggregation of existing aggregates and inhibited formation of large, insoluble species. Moreover, \u03b1SN aggregation and disaggregation products formed in the presence of betanin or its derivatives exhibited significantly lower cytotoxicity than those formed in their absence. Specifically, cells treated with aggregates formed in the presence of 50 \u00b5M betaxanthin Bxn-B showed 100% viability, while those treated with disaggregation products formed in the presence of 100 \u00b5M betaxanthin Bxn-A showed 20% greater viability than those treated with untreated disaggregates. Molecular docking revealed interactions between betaxanthins and key \u03b1SN residues, suggesting destabilization mechanisms. Docking analyses with five ROS-PPI network key proteins-C5, CDC42, BCL2, CDKN1A, and CDKN1B-indicated potential roles in inhibiting oxidative stress-related pathways. Drug-likeness predictions indicated that the derivatives enhanced pharmacological potential, making them promising candidates for PD treatment.\n\nID: 42076898\nTitle: Copper Overload Affects \u03b1-Synuclein Clearance Mechanisms in a Parkinson's Disease In Vitro Model.\nAbstract: Parkinson's disease (PD) is a common neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta and the formation of Lewy bodies, abnormal protein aggregates primarily composed of \u03b1-synuclein. Copper, an essential trace element, plays a role in \u03b1-synuclein aggregation and PD pathogenesis. This study examines the effects of copper overload on \u03b1-synuclein clearance pathways, focusing on autophagy and the ubiquitin-proteasome system (UPS) in dopaminergic SH-SY5Y neuroblastoma cells. Copper exposure enhances autophagosome formation, as indicated by increased Beclin-1 and LC3-II levels, and impairs autophagic flux, evidenced by LC3-II accumulation in the presence of chloroquine. Concurrently, copper increases polyubiquitinated proteins, suggesting UPS dysfunction, which is confirmed through MG132 treatment. These disruptions lead to the accumulation and aggregation of \u03b1-synuclein, particularly in its phosphorylated form. Immunofluorescence reveals neurite-localized \u03b1-synuclein aggregates, consistent with copper's role in \u03b1-synuclein pathology. This study highlights copper dyshomeostasis as a contributor to impaired \u03b1-synuclein clearance through autophagy and UPS dysfunction, advancing the understanding of PD's molecular basis.\n\nID: 42067182\nTitle: Unraveling the role of non-coding RNAs in Parkinson's disease: Molecular mechanisms and therapeutic insights.\nAbstract: Parkinson disease (PD) is a progressive neurodegenerative disorder characterized by the selective loss of dopaminergic neurons in the substantia nigra pars compacta and pathological accumulation of \u03b1-synuclein in Lewy bodies. In this process, a set of non-coding RNAs including miRNAs, lncRNAs, and circRNAs form key regulatory layers in the pathogenesis of the disease and directly affect \u03b1-synuclein homeostasis, mitochondrial function, oxidative stress, neuroinflammation, autophagy, and proteostasis. Dysregulation of miRNAs targets neurosensitive pathways; miR-7 and miR-153 inhibit SNCA translation, miR-27a/b and miR-103a-3p regulate the PINK1/Parkin axis in mitophagy, and miR-155, together with miR-135b, modulate the regulation of the NF-\u03baB/NLRP3 dependent inflammasome. On a broader level, lncRNAs with destructive roles such as NEAT1, HOTAIR, MALAT1, SNHG1, UCA1 and GAS5 increase \u03b1-synuclein accumulation and impair autophagy through ceRNA and chromatin remodeling mechanisms. On the other hand, circRNAs with their stable circular structure alter posttranslational regulation through miRNA sponging; such that circSNCA, CDR1as and circSLC8A1 enhance \u03b1-synuclein load, impair mitophagy and exacerbate oxidative stress, while circDLGAP4 has a neuroprotective function. Data from single-cell sequencing and multi-omics reveal cell-specific patterns of ncRNA dysregulation in microglia, astrocytes and dopaminergic neurons, highlighting their importance in early diagnosis, molecular stratification of patients and development of targeted therapies.\n\nID: 42033266\nTitle: Lysosome-Acidifying Nanoparticles Rescue A30P \u03b1-Synuclein Induced Neuronal Death in Cellular and Drosophila Models of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is the second most common neurodegenerative disorder, affecting over 10 million people worldwide. It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation.\n\nID: 42002068\nTitle: Neuronal vulnerability in Parkinson's disease: insights from murine \u03b1-synuclein pathology models.\nAbstract: Parkinson's disease (PD) is characterised by the progressive degeneration of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). Lewy bodies- the defining neuropathological hallmark of PD-are chiefly composed of aggregated forms of \u03b1-synuclein (\u03b1-syn). Despite the widespread presence of \u03b1-syn pathology, neurodegeneration is often selective, and the mechanisms underlying the vulnerability of specific neuronal populations in PD remain poorly understood. This review critically evaluates \u03b1-syn-based models of PD, with a focus on murine systems, to determine how they have illuminated the cellular and molecular determinants of neuronal susceptibility. Across murine \u03b1-syn pathology models, degeneration reliably affects dopaminergic neurons (TH+) in SNpc, with preferential vulnerability of aldehyde dehydrogenase 1 family member A1- (ALDH1A1-) neurons in the dorsal SNpc, as well as noradrenergic and cholinergic (ChAT+) neurons, and parvalbuminergic interneurons, depending on the experimental context. In these models, degeneration is accompanied by mitochondrial and lysosomal dysfunction, calcium dysregulation, presynaptic failure, and neuroinflammatory activation. This review integrates transcriptomic and proteomic data across murine \u03b1-synuclein models, revealing differences in selective neuronal vulnerability across models depending on spatiotemporal context and interplay between intrinsic neuronal properties and extrinsic factors. This review paper underscores the need for stage-resolved mapping of vulnerable neuronal and non-neuronal populations in PD and, as well as careful alignment of model selection with the specific mechanistic questions under investigation. It also highlights the need for further single cell and spatiotemporally resolved in vivo studies using reliable molecular markers.\n\nID: 41981587\nTitle: Peripheral immunochemical considerations in Parkinson disease: sources, targets and crosstalk mechanisms.\nAbstract: BACKGROUND: Parkinson disease is a progressive neurodegenerative disorder characterized by the degeneration of dopamine neurons in the substantia nigra pars compacta, leading to a broad spectrum of motor and non-motor symptoms. Increasing evidence indicates that chronic inflammation and immune dysregulation are central to its pathogenesis. The activation of microglia, astrocytes, and circulating monocytes establishes a self-perpetuating cycle of inflammation and neuronal injury, positioning monocytes as a key interface between systemic and central immune responses. MAIN TEXT: The discovery of misfolded alpha-synuclein in peripheral tissues, such as the gut, olfactory mucosa and skin, supports a multisystem view of the disease, suggesting that peripheral pathology may precede and drive neurodegeneration through neuroanatomical and microbiota-mediated routes. Monocytes exhibit altered subset composition, impaired phagocytic capacity, and metabolic reprogramming involving mitochondrial and lysosomal dysfunction, partly linked to mutations in the LRRK2 and GBA1 genes, which further sustain inflammation and alpha-synuclein aggregation. In parallel, the disruption of the blood-brain and meningeal barriers facilitates immune cell infiltration and amplifies neuroinflammatory signalling within the brain. Elevated circulating cytokines, chemokines, and inflammasome activation reflect a primed immune state correlated with disease progression, whereas metabolic disturbances in tryptophan, purine, lipid, and microbiota-derived pathways connect peripheral metabolic imbalance to neuronal vulnerability. Finally, exosomes act as critical mediators of communication between the periphery and the brain. Owing to their ability to cross the blood-brain barrier bidirectionally, they contribute to the dissemination of alpha-synuclein and transport miRNAs that promote oxidative stress, two key mechanisms underlying Parkinson disease pathology. These features position exosomes as both promising targets for biomarker discovery and effective vehicles for the targeted delivery of therapeutic agents to the central nervous system. CONCLUSIONS: Together, this review highlights peripheral inflammation and misfolded alpha-synuclein as pivotal contributors to neuroinflammatory mechanisms in Parkinson disease, emphasizing monocyte-related pathways as promising targets for disease monitoring and intervention.\n\nID: 41977181\nTitle: Copper Dyshomeostasis Affects \u03b1-Synuclein Clearance Mechanisms in Parkinson's Disease: Insights from In Vitro Models and Translational Evidence.\nAbstract: Parkinson's disease (PD) is characterized by the progressive degeneration of dopaminergic neurons and the accumulation of \u03b1-synuclein-rich inclusions, largely resulting from impaired protein clearance mechanisms. Copper is an essential redox-active metal in the central nervous system (CNS), but alterations in its homeostasis can promote oxidative stress, mitochondrial dysfunction, and proteostatic failure. In vitro studies indicate that copper can promote \u03b1-synuclein misfolding, enhance oxidative stress, and interfere with both the ubiquitin-proteasome system (UPS) and the autophagy-lysosome pathway (ALP). In this review, we critically evaluate mechanistic evidence from cellular models, integrating available animal and clinical data to assess the biological significance of copper-mediated impairment of \u03b1-synuclein clearance. We highlight the current research, identify methodological limitations, and discuss whether copper imbalance acts as a primary pathogenic trigger or as a disease-modifying amplifier of proteostatic failure. Furthermore, we consider the translational implications of selectively modulating intracellular copper pools as a therapeutic strategy in PD. Finally, we will highlight unresolved issues, methodological limitations, and emerging targeted therapeutic prospects.\n\nID: 41957923\nTitle: Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?\nAbstract: The enteric nervous system (ENS), a key component of the gut-brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)-a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or environmental contamination. Emerging evidence suggests that FCs may initiate or amplify neurodegenerative processes, yet their effects on the ENS and their impact in gut-to-brain communication remain insufficiently characterized. This systematic review synthesizes current evidence on FCs-induced effects on the ENS and its involvement in mediating neurotoxicity from dietary toxicants exposure. Following PRISMA guidelines, 67 studies were included pertaining to cellular or mammalian experimental models exposed to FCs via enteral routes, reporting ENS-related outcomes or studying vagal involvement in modulating FC toxicity. The main FCs evaluated were pesticides, toxins, bisphenols, acrylamide, manganese, and micro-/nanoplastics. Across studies, FCs consistently induced neurochemical remodeling of the ENS, activation of enteric glia, often coupled with intestinal alterations. Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain. Vagotomy models confirmed that disrupting ENS-CNS communication attenuates FC-related central neurotoxicity, supporting the involvement of food toxicants in gut-to-brain propagation of neurotoxic signals. These findings support the body-first hypothesis of PD and position the ENS as a critical, yet underinvestigated interface in exposome-related neurotoxicology. The review highlights research gaps and the need for improved models and long-term, low-dose studies reflecting realistic FC exposure.\n\nID: 41943176\nTitle: DAPK1-Mediated Parkin Inactivation Enhances Neurotoxicity via MITOL-Dependent Degradation.\nAbstract: Parkinson's disease (PD) is characterised by progressive neurodegeneration and is marked by the formation of Lewy bodies, which are intracellular aggregates primarily composed of \u03b1-synuclein. Mitochondrial dysfunction and impaired protein degradation pathways are thought to play critical roles in PD progression, contributing to the loss of dopaminergic neurons in the substantia nigra. Phosphorylation of \u03b1-synuclein has been shown to promote its aggregation, underscoring its potential role in disease progression. Parkin, an E3 ubiquitin ligase, is widely regarded as a pleiotropic neuroprotective protein that modulates the mitochondrial quality control, as well as metabolic turnover and the accumulation of \u03b1-synuclein. Death-associated protein kinase 1 (DAPK1), which is involved in the regulation of apoptosis and autophagy, has recently emerged as an important factor in neurodegeneration. While DAPK1 has been implicated in Alzheimer's disease through its role in tau aggregation and amyloid-\u03b2 production, our findings suggest that DAPK1 may also influence PD-related pathways by phosphorylating parkin at Ser136 and Ser198. This phosphorylation promotes the mitochondrial transport of parkin, enhancing interaction with mitochondria-localised E3 ubiquitin ligase MITOL and consequently leading to the degradation of parkin. Given the neuroprotective role of parkin, its reduction increases the vulnerability of neurons to 6-hydroxydopamine-induced toxicity, potentially contributing to decreased neuronal survival. Together, these findings suggest that DAPK1 functions as a previously unrecognised modulator of parkin and could potentially influence PD-related neurodegenerative processes. This pathway may provide a mechanistic link between mitochondrial dysfunction, \u03b1-synuclein pathology and neuronal cell death.\n\nID: 41941974\nTitle: Intelligent delivery of autophagy-targeting chimeric peptides by engineered exosomes for the degradation of \u03b1-synuclein.\nAbstract: Targeted degradation of the aggregated \u03b1-synuclein holds tremendous potential for treating Parkinson's disease (PD). However, most of the developed aggregated \u03b1-synuclein-specific degraders, e.g., autophagy-targeting chimeric peptides, are limited by the blood-brain barrier (BBB), substantia nigra (SN) neuron targetability, and intracytoplasmic release. To overcome these obstacles, we constructed an engineered exosome (EXO) equipped with surficial glucose-regulated protein 94 (GRP94)-targeting peptide N, luminal \u03b1-synuclein-degrading peptide P1, and cathepsin-B-cleavable GFLG as the linker between the exosome skeleton protein and P1, termed NEXOGFLG-P1. We verified that the NEXOGFLG-P1 exosomes could cross the BBB and target diseased SN neurons in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (MPTP)-induced PD model mice. Following fusion with endosomes, the exposed P1 was released into the cytoplasm by cytoplasmic cathepsin B-mediated GFLG cleavage to degrade \u03b1-synuclein. Collectively, the NEXOGFLG-P1 exosomes exhibit a significant degradation effect on \u03b1-synuclein aggregates, providing a proof-of-concept platform for treating PD. STATEMENT OF SIGNIFICANCE: Targeted degradation of \u03b1-synuclein aggregates holds tremendous potential for the etiological treatment of Parkinson's disease (PD). However, most of current \u03b1-synuclein-specific degraders are stuck with low blood-brain barrier permeability, poor targetability for diseased cells, and uncontrolled release. Notably, \u03b1-synuclein predominantly affects neurons in the substantia nigra (SN) region rather than the whole brain. To overcome these obstacles, we constructed an engineered exosome, termed NEXOGFLG-P1, to specially deliver and release autophagy-targeting chimeric peptide to degrade \u03b1-synuclein in the diseased SN neurons through the autophagy-lysosomal pathway. The engineered exosomes exhibit the great potential in targeting diseased SN neurons and degrading \u03b1-synuclein aggregates, providing a proof-of-concept therapeutic platform for treating PD.\n\nID: 41932887\nTitle: TMBIM6 enhances dopaminergic neuron survival by modulating the IRE1a pathway in Parkinson's disease.\nAbstract: The core pathological hallmark of Parkinson's disease (PD) is the progressive degeneration of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNpc), driven by misfolding and aggregation of a-synuclein (aSyn) into Lewy bodies. This triggers severe cellular dysfunction, including endoplasmic reticulum (ER) stress and the dysregulation of the unfolded protein response (UPR). TMBIM6, an anti-apoptotic ER protein, inhibits the UPR sensor IRE1a. Although TMBIM6 exhibits neuroprotective effects in neurological disorders, its role in PD-related DAergic neuron survival remains unknown. We report that TMBIM6 mRNA is increased in cellular models exposed to 6-hydroxydopamine (6-OHDA), rotenone, or aSyn preformed fibrils (PFFs), whereas TMBIM6 protein levels are elevated in postmortem PD SNpc, indicating translational relevance. Modulating TMBIM6 expression in DAergic cells and primary neurons showed that knockdown increased aSyn toxicity, while overexpression is protective. Single-cell RNA-seq analysis of PD SN revealed selective disruption of TMBIM6 co-expression with key UPR effectors (HSPA5, ERN1, and XBP1), and reduced TMBIM6 levels in vulnerable DAergic neurons. Mechanistically, TMBIM6 directly binds IRE1a, and aSyn PFFs disrupt this complex, leading to IRE1a activation; genetic or pharmacological IRE1a inhibition prevented cell death in TMBIM6-deficient cells. In vivo, TMBIM6 downregulation in Drosophila melanogaster worsens rotenone-induced DAergic neuron degeneration and motor impairments, while adeno-associated virus (AAV)-mediated TMBIM6 overexpression in mice improves motor function and neuron survival. Our results demonstrate that TMBIM6 modulates ER stress responses, promoting DAergic neuron survival by regulating IRE1a activity. Consequently, the TMBIM6/IRE1a axis represents a promising therapeutic target for mitigating neurodegeneration in PD and related disorders.\n\nID: 41841711\nTitle: Simultaneous inhibition of mTOR and STING as an approach to reduce alpha-synuclein and lysosphingolipid levels in peripheral blood monocytederived macrophages and the SH-SY5Y cell line: implications for therapy of Parkinson's disease.\nAbstract: The combined effects of two inhibitors, Torin 1, acting on mTOR, a key regulator of autophagy, and H-151, inhibiting STING, a key regulator of inflammation, on the autophagolysosomal system, have been studied in a primary culture of peripheral blood macrophages from healthy donors and the SH-SY5Y neuroblastoma cell line. Combined use of these drugs resulted in a decrease in the levels of lysosphingolipids, triggering alpha-synuclein oligomerization, as well as a decrease in the levels of monomeric and neurotoxic phosphorylated (Ser129) alpha-synuclein and an increase in tyrosine hydroxylase. These results open new prospects for the use of combination therapy with these proposed drugs in the treatment of both diseases associated with lysosomal dysfunction and neurodegenerative pathologies.\n\nID: 41833769\nTitle: Targeting TREM2 to disentangle neuroinflammation and \u03b1-Syn pathological propagation in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disorder of the central nervous system (CNS) that predominantly affects middle-aged and elderly populations, characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the abnormal aggregation of \u03b1-synuclein (\u03b1-Syn) as its core pathological features. Its pathogenesis is complex, and the crosstalk among genetic factors, microenvironmental factors and neuroinflammation has emerged as a central research focus at present. Triggering receptor expressed on myeloid cells 2 (TREM2), a key regulator of microglial function, is deeply implicated in the pathophysiological processes of PD by mediating multiple biological events, including phagocytic clearance, inflammatory homeostasis, autophagy regulation and neuronal repair. In recent years, Advances in genomics, cell biology and model animal technologies, the genetic association between TREM2 gene variants and PD, the regulatory role of the TREM2 signaling pathway in \u03b1-Syn pathological propagation, and its dual effects in neuroinflammation and dopaminergic neuron protection have been gradually elucidated. This review systematically summarizes the molecular structure and signal transduction mechanisms of TREM2, with a focus on elaborating the multidimensional roles of the TREM2 signaling pathway in the regulation of \u03b1-Syn metabolism, microglial polarization, dopaminergic neuron survival and non-motor symptoms in PD. We also conduct an in-depth analysis of the pathological significance of TREM2 gene variants and their interactive effects with microenvironmental factors, and discuss therapeutic strategies and research progress for PD targeting the TREM2 signaling pathway. Finally, we summarize the current research controversies and future directions, aiming to provide new insights into the mechanistic investigation and precision therapy of PD.\n\nID: 41759571\nTitle: Mitochondrial dysfunction and disrupted neuronal lipid homeostasis in Parkinson's disease: Potential mechanisms and therapeutic implications.\nAbstract: Parkinson's disease (PD) is a multifactorial neurodegenerative disorder characterised by dopaminergic neuron loss and pathological accumulation of alpha-synuclein. Emerging evidence highlights a crucial interplay between mitochondrial dysfunction and disrupted lipid homeostasis as central mechanisms driving PD pathogenesis. This scoping review synthesises current evidence on the relationship between mitochondrial dysfunction and neuronal lipid dysregulation in PD and identifies potential therapeutic targets within these intersecting pathways. Following the PRISMA-ScR guidelines, a comprehensive literature search was conducted across PubMed, Embase, and Web of Science for studies published between 2015 and 2025. Two independent reviewers screened and selected eligible studies based on predefined inclusion criteria. Analysis revealed four central interconnected pathological mechanisms: ferroptosis, alpha-synuclein-lipid interactions, mitochondrial dysfunction, and impaired autophagy/mitophagy. These mechanisms collectively contribute to oxidative stress, membrane destabilisation, and bioenergetic collapse, driving dopaminergic neuronal vulnerability. The findings underscore a complex, bidirectional relationship between mitochondrial dysfunction and lipid dysregulation in PD. Therapeutic strategies targeting iron accumulation, lipid peroxidation, and alpha-synuclein aggregation are promising. However, further mechanistic studies are required to clarify these interactions and advance the development of effective disease-modifying interventions.\n\nID: 41758265\nTitle: Rab8a dysregulation in Parkinson's disease: A convergence of genetic and molecular pathologies.\nAbstract: Parkinson\u2019s disease (PD) is a progressive neurodegenerative disorder characterized by dopaminergic neuron loss in the substantia nigra and \u03b1-synuclein (\u03b1Syn) accumulation in Lewy bodies. Genetic mutations in upstream regulators of cellular pathways, such as LRRK2, VPS35, TMEM230, and PINK1, are increasingly implicated in dysregulating Rab8a GTPase function, potentially disrupting its roles in \u03b1Syn homeostasis, lysosomal clearance, autophagy, membrane trafficking, lipid metabolism, and ciliogenesis. Rab8a protectively interacts with S129-phosphorylated \u03b1Syn to promote the formation of less toxic aggregates, whereas its depletion impairs lysosomal function and \u03b1Syn degradation. Gain-of-function LRRK2 and VPS35 mutations phosphorylate Rab8a at threonine 72 (Thr72), exacerbating PD pathology. In contrast, loss-of-function TMEM230 mutations have been linked to reduced Rab8a levels in some models, impairing vesicular trafficking and autophagy, whereas loss-of-function PINK1 mutations abolish serine 111 (Ser111) phosphorylation in a PINK1-dependent manner. This loss of phosphorylation impairs Rab8a activation (via reduced Rabin8 GEF binding) and removes a regulatory constraint on pathogenic LRRK2-mediated Thr72 phosphorylation. In vivo, LRRK2 and PINK1 mutations mechanistically converge on striatal ciliogenesis defects, reducing glial-derived neurotrophic factor (GDNF) signaling and neuroprotection. Although preclinical data strongly implicate Rab8a dysregulation as a downstream effector of multiple PD-associated genetic pathways, direct evidence of altered Rab8a expression or phosphorylation in human PD brain tissue is currently lacking. This review emphasizes the emerging role of Rab8a in PD pathogenesis and highlights its therapeutic potential.\n\nID: 41701385\nTitle: Rotating Magnetic Field Therapy Induces System-Level Neuroprotection in A53T \u03b1-Synuclein Transgenic Mice Through Coordinated Suppression of Cellular Stress Pathways.\nAbstract: Current therapeutic strategies for Parkinson's disease (PD) focus exclusively on symptomatic management without addressing underlying disease progression. Despite decades of research emphasizing the enhancement of the cellular defense pathway, disease-modifying treatments remain elusive. We evaluated rotating magnetic field (RMF) therapy in A53T transgenic mice harboring a familial PD-associated mutation. Transgenic and wild-type animals (n\u2009=\u20098 per group) received RMF treatment (4\u00a0Hz, 0.4 T, 2\u00a0h daily) for six months. Motor function, muscle strength, and neuropathological markers were assessed. Comprehensive transcriptomic and proteomic analyses were performed to elucidate the molecular mechanisms involved. Untreated A53T transgenic mice exhibited progressive motor decline (51% reduction in locomotor activity, 39% decrease in muscle strength) accompanied by the accumulation of pathological \u03b1-synuclein aggregates. RMF-treated transgenic mice demonstrated significant functional recovery, with 78% wild-type locomotor activity and 80% normal muscle strength, with a marked reduction in \u03b1-synuclein pathology. Molecular profiling revealed unexpected suppression of hyperactivated stress response pathways, including mTOR signaling, autophagy, and oxidative stress responses (NES = -2.05 to -2.65, FDR\u2009<\u20090.01), whereas metabolic defense mechanisms such as glutathione biosynthesis were increased (NES\u2009=\u20092.18, FDR\u2009<\u20090.001).These findings suggest that normalization of aberrant stress signaling through RMF therapy represents a novel disease-modifying strategy with potential applicability to other neurodegenerative disorders characterized by proteostasis dysfunction.\n\nID: 41663306\nTitle: [Research progress on the molecular genetic mechanism of Parkinson's disease].\nAbstract: The pathogenesis of Parkinson's disease is closely related to genetic factors. This article has systematically reviewed the research progress of molecular genetic mechanism on Parkinson's disease by focusing on the role of six high-penetrance pathogenic genes (SNCA, LRRK2, PRKN, PINK1, PARK7, and VPS35) and some risk genes (such as GBA1). These genetic variants eventually converge in three core pathogenic biological pathways, including lysosomal-autophagy pathway disorder, mitochondrial quality control disorder and \u03b1-synuclein metabolic abnormality. In-depth understanding of these molecular mechanisms is of great significance for the development of targeted therapy and realization of precision medicine for this disease.\n\nID: 41637953\nTitle: MONNA alleviates MPTP-induced Parkinson's disease in zebrafish by activating TFEB dependently on ER Calcium.\nAbstract: A-synuclein aggregation is a biomarker of Parkinson's disease (PD) whose feature is the progressive loss of dopaminergic neuron in the middle brain. The removal of a-synuclein aggregation through autophagy-lysosome pathway is a promising strategy for PD treatment. Transcription factor EB (TFEB) is a master regulator of autophagic and lysosomal biogenesis and function. Here, we report a library screen of intracellular Ca2+ inducers to identify small-molecule agonists of TFEB and discover MONNA can promote autophagic and lysosomal activity. Notably, MONNA facilitates the reduction of pathological a-synuclein in the Parkinson's disease model both in vitro and in vivo, and ameliorates PD-like behaviors in zebrafish. Mode of action studies reveal MONNA induces TFEB nuclear translocation through a Ca2+-dependent mechanism involving Calcineurin (CaN). Endoplasmic reticulum (ER) but not lysosome Ca2+ is critical to MONNA-induced TFEB activation and autophagy induction. Furthermore, Sarcoendoplasmic reticulum calcium ATPase (SERCA) pump of ER modulates TFEB nuclear translocation induced by MONNA. Our findings demonstrate that MONNA is the first ER Ca2+-dependent small synthetic TFEB agonist promoting the degradation of a-synuclein aggregates and alleviating Parkinson's disease. This ER Ca2+-Calcineurin-TFEB signaling pathway would broaden the way to develop drugs for PD.\n\nID: 41623384\nTitle: Deciphering the modulatory role of short-chain fatty acids in Parkinson's disease via phosphorylation-dependent signaling mechanisms.\nAbstract: Parkinson's disease (PD), the world's second most prevalent neurodegenerative disorder, is characterized by progressive neuronal degeneration mediated through intricate pathological mechanisms. Phosphorylation signaling pathways have been increasingly recognized as critical modulators in the development and progression of PD. Meanwhile, short-chain fatty acids (SCFAs), primarily produced by gut microbiota, have shown considerable neuroprotective potential by promoting autophagy, alleviating mitochondrial dysfunction, and regulating neuroinflammatory responses. Recent research suggests that SCFAs may influence the phosphorylation dynamics of key signaling pathways, including MAPKs, NF-\u03baB, JAK/STAT, PI3K/Akt, AMPK, and Nrf2/Keap1/ARE, thereby modulating disease pathophysiology. This review aims to systematically evaluate how SCFAs modulate phosphorylation pathways to influence neuroinflammation, \u03b1-synuclein aggregation, and mitochondrial dysfunction in PD. By investigating this issue, we identify potential molecular targets and propose future research directions, offering new insighreviewts and strategies for the development of novel therapeutic and preventive interventions for PD.\n\nID: 41622607\nTitle: Zinc-Mediated Lysosomal Destabilization Links Mitochondrial Damage to Neuronal Death in a Cellular MPP+ Model of Parkinson's Disease.\nAbstract: Dysregulation of autophagy and lysosomal function is central to Parkinson's disease (PD), yet the upstream mechanisms leading to lysosomal failure remain unclear. Across primary mouse cortical neurons, MT-3 deficient primary mouse astrocytes, human iPSC-derived midbrain dopaminergic neurons, and Rho0 CHO cells lacking mitochondrial respiration, we investigated how mitochondrial stress perturbs zinc (Zn2+) homeostasis and lysosomal integrity. We identify intracellular zinc as a critical mediator linking mitochondrial dysfunction to lysosomal membrane permeabilization (LMP) and neuronal death. Inhibition of mitochondrial complex I by 1-methyl-4-phenylpyridinium (MPP+) elevated reactive oxygen species (ROS) and intracellular zinc, jointly driving LMP. Blocking either ROS or zinc markedly attenuated lysosomal damage and cell death, demonstrating that both act upstream of LMP. To define zinc regulation, we examined metallothionein-3 (MT-3), a brain-enriched zinc-binding protein. MT-3-deficient astrocytes were more vulnerable to MPP+ and zinc overload (ZnCl2) but paradoxically resistant to hydrogen peroxide (H2O2), suggesting that MT-3 buffers cytosolic zinc during mitochondrial injury or extracellular zinc influx yet can release bound zinc under oxidative conditions. Using Rho0 cells, we show that MPP+ toxicity depends on mitochondrial ROS, as loss of mitochondrial function nearly abolished cell death. However, Rho0 cells were highly sensitive to ZnCl2 and H2O2 and exhibited markedly reduced lysosomal abundance, indicating limited capacity to sequester zinc and increased susceptibility to zinc-mediated injury. These findings support a coordinated system in which lysosomes and zinc-binding proteins maintain zinc homeostasis. When cytosolic zinc rises, its accumulation within lysosomes induces LMP and accelerates cell death. Collectively, our results identify intracellular zinc as an upstream trigger of lysosomal dysfunction and neurodegeneration. Zinc-mediated LMP provides a mechanistic link between mitochondrial injury, impaired autophagic flux, and \u03b1-synuclein pathology in PD. Enhancing zinc homeostasis and lysosomal resilience may offer promising therapeutic strategies.\n\nID: 41596551\nTitle: Identification of KHS-101 as a Transcription Factor EB Activator to Promote \u03b1-Synuclein Degradation.\nAbstract: Neurodegenerative disorders are increasingly linked to a progressive decline in lysosomal function. Activating Transcription Factor EB (TFEB), a master regulator of lysosomal biogenesis and autophagy, has therefore emerged as a promising therapeutic strategy to enhance cellular clearance in these conditions. In this study, we identified KHS-101 as a novel TFEB activator through a high-throughput screen of blood-brain-barrier-permeable small molecules. We demonstrated that KHS-101 promotes TFEB nuclear translocation, enhances lysosomal biogenesis and proteolytic activity, and increases autophagic flux. Furthermore, KHS-101 significantly accelerates the degradation of pathogenic A53T mutant \u03b1-synuclein in a cellular model of Parkinson's disease, suggesting its potential to mitigate \u03b1-synuclein-mediated proteotoxicity and hold neuroprotective potential. Our findings identify KHS-101 as a potent TFEB activator and highlight the therapeutic potential of modulating the autophagy-lysosomal pathway for treating Parkinson's disease and related disorders.\n\nID: 41580402\nTitle: Micro-nanoplastics and Parkinson's disease: evidence and perspectives.\nAbstract: With the intensification of global plastic pollution, the potential threats posed by micro- and nanoplastics (MPs/NPs) to human health have become a major concern. MPs/NPs enter the organism through ingestion, inhalation, and skin contact, subsequently accumulating in multiple organs-particularly the brain. Increasing experimental and epidemiological evidence implicates MPs/NPs in the development of Parkinson's disease (PD). Preclinical research models indicate that MPs/NPs may accelerate both the initiation and progression of PD by facilitating \u03b1-synuclein misfolding and aggregation, triggering neuroinflammatory cascades, elevating oxidative stress, and impairing mitochondrial function. To further investigate the causal role of MPs/NPs in PD, upcoming studies should emphasize well-designed, large-scale prospective cohorts to assess individual exposure to plastic-related pollutants, elucidate the pathways of MPs/NPs into the central nervous system, establish safety thresholds for their neurotoxicity, explore the correlation between exposure levels and central nervous system accumulation, clarify the temporal relationship between MPs/NPs accumulation and PD pathology and symptom onset, and identify the neuropathological mechanisms triggered by relevant concentrations of MPs/NPs. Such data will be instrumental in informing preventive and potentially interventional strategies, while offering actionable insights into the interaction between MPs/NPs and PD.\n\nID: 41576771\nTitle: Identification of pesticides associated with an increased risk of Parkinson's disease using a multi-screen approach.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disease characterized by aggregation and transmission of alpha-synuclein (\u03b1-syn) protein and loss of dopaminergic neurons. The etiology of PD is multifactorial, involving both genetic and environmental factors. Pesticide exposure has been associated with PD, and with thousands of registered pesticides in the United States, it is still unclear which of these chemically and structurally diverse pesticides confer this association. The population-based case-control Parkinson's, Environment, and Gene (PEG) study based in the California Central Valley, an agricultural hub servicing much of the nation, offers a promising opportunity to investigate this relationship and identify likely environmental risk factors contributing to PD risk. In this study, 62 pesticides with reported agricultural use in the Central Valley were independently evaluated in 2 cell-based assays testing for pesticides that promote \u03b1-syn transmission and alter autophagy. To further stratify and prioritize pesticide candidates, pesticides that were positive in the 2 cell-based screens (double hits) were filtered through a newly described pesticide-wide association analysis to agnostically identify relevant real-world exposures. Using these selection criteria, 6 pesticides were identified as triple hits and were tested for dopaminergic neurotoxicity in an in vivo zebrafish (ZF) model. Of these 6 pesticides, 4 pesticides contributed to aminergic neuron loss in ZF larvae. The majority of the pesticides identified in our screens have not previously been implicated as risk factors for PD but should be considered in future studies.\n\nID: 41507136\nTitle: Calcium overload induced mitochondrial and lysosomal dysfunction is regulated by Tousled-like kinase in a-synucleinopathy.\nAbstract: As a pathological hallmark of Parkinson's disease (PD), a-synucleinopathy induces various cellular damages, including calcium overload, mitochondrial and autophagic dysfunction, ultimately resulting in dopaminergic neuron death. However, the hierarchy of these detrimental events remains unclear. It is well established that a-synuclein can induce calcium overload through diverse mechanisms. To assess whether calcium overload plays a crucial detrimental role, we established a calcium overload model in Drosophila and conducted genetic screening. Our findings indicate that calcium overload caused mitochondrial damage and lysosomal dysfunction, leading to cell death, and these cytotoxic processes were significantly mitigated by the loss of Tousled-like kinase (TLK). Notably, the loss of TLK also ameliorated defects induced by a-synuclein overexpression in Drosophila. This suggests that calcium overload is a critical event in a-synucleinopathy. In mammalian cells and mice, calcium overload activated TLK2 (the homologue of Drosophila TLK) by enhancing TLK2 phosphorylation, which increases TLK2 kinase activity. Increased TLK2 phosphorylation was detected in the brains of GluR1Lc and a-synuclein overexpression mice, suggesting that TLK2 is activated under these pathological conditions. Furthermore, TLK2 knockout mice exhibited rescue of multi-aspect cytotoxicity induced by calcium overload and a-synuclein overexpression. Our research demonstrates that TLK2 activation by calcium overload appears to be a pivotal step in the progression of PD. This finding provides a potential link between calcium overload, the subsequent mitochondrial and lysosomal dysfunction observed in the disease.\n\nID: 41465169\nTitle: Underlying Mechanisms of GBA1 in Parkinson's Disease and Dementia with Lewy Bodies: Narrative Review.\nAbstract: Background/Objectives: Parkinson's disease (PD) and Dementia with Lewy Bodies (DLB) are neurodegenerative disorders characterized by the accumulation of misfolded alpha-synuclein protein in the brain. Mutations in the glucocerebrosidase 1 (GBA1) gene have been identified as a significant genetic risk factor for both PD and DLB. GBA1 encodes for the lysosomal enzyme glucocerebrosidase, which is responsible for the breakdown of glucosylceramide (GC). Deficiencies in glucocerebrosidase activity lead to the accumulation of glucosylceramide within lysosomes, contributing to lysosomal dysfunction and impaired protein degradation. The aim of this narrative review is to update the underlying mechanisms by which GBA1 mutations contribute to the pathogenesis of PD and DLB. Methods: A comprehensive literature search was conducted across four major electronic databases (PubMed, Web of Science (Core Collection), Scopus, and Embase) from inception to 8 November 2025. The initial search identified approximately 1650 articles in total, with the number of hits from each database being as follows: PubMed (~450), Web of Science (~380), Scopus (~520), and Embase (~300). Results: The mechanism by which mutations in the GBA1 gene contribute to PD involves both loss-of- function and gain-of-function pathways, which are not mutually exclusive. Typically, GBA1 mutations lead to a loss of function by reducing the activity of the GCase enzyme, impairing the autophagy- lysosomal pathway and leading to \u03b1-synuclein accumulation. However, some mutant forms (GBA1L444P) of the GCase enzyme can also acquire a toxic gain of function, contributing to \u03b1-synuclein aggregation through mechanisms like endoplasmic reticulum stress and misfolding. While Venglustat effectively reduced GC levels, a key marker associated with GBA1-PD, the lack of clinical improvement led to the discontinuation of its development for this indication. Conclusions: GBA1-mediated lysosomal and lipid dysregulation represents a key pathogenic axis in PD and DLB. Understanding these mechanisms provides crucial insight into disease progression and highlights emerging therapeutic strategies-such as pharmacological chaperones, substrate reduction therapies, and gene-targeted approaches-aimed at restoring GCase function and lysosomal homeostasis to slow or prevent neurodegeneration.\n\nID: 41460324\nTitle: Revisiting the alpha-synuclein paradox in melanoma-Parkinson's disease connection: more than a tale of two cell fates.\nAbstract: Since the first report in 1972, several studies have documented an association between Parkinson\u2019s disease (PD) and melanoma. Up to 20-fold increased risk of melanoma was reported in PD patients, while a personal/family history of melanoma was linked to a 1.85-fold PD risk. Neurons and melanocytes, which both derive from the neuroectodermal crest, share biological pathways that may be dysregulated in both diseases. In particular, accumulation of the alpha-synuclein (\u03b1-syn, SNCA) protein, a pathological hallmark of PD, is also observed in melanoma. Indeed, dysregulated \u03b1-syn proteostasis is known to disrupt several biological pathways which can co-incidentally, albeit paradoxically contribute to both neurodegeneration and hyper-proliferative cell growth. These include abnormalities in dopamine (DA), melanin, and iron metabolism, oxidative stress, DNA damage/repair response, inflammation, as well as alterations in mitochondrial function, and cell-clearing machinery. Although \u03b1-syn depletion was shown to attenuate melanoma cell proliferation and neurodegeneration, it remains unclear whether \u03b1-syn accumulation is a mere culprit of disease, if it represents a common outcome from shared upstream mechanisms, or, finally, a compensatory response to cellular stress. In an effort to elucidate how \u03b1-syn bridges melanomagenesis and the neurodegenerative events of PD, this review discusses specific cellular and molecular pathways related to \u03b1-syn proteostasis, including environmental factors implicated in melanocytic transformation, such as UV radiation. Addressing open questions and establishing novel experimental models remain essential for developing effective therapeutic approaches to target melanoma and PD without overlooking their comorbidity.\n\nID: 42191076\nTitle: Long-term low-dose nanoplastic exposure induces neurotoxicity with oxidative brain damage.\nAbstract: The potential health impacts of nanoplastic exposure have attracted significant scientific interest, with emerging evidence linking their presence to various human diseases. Alarmingly, polystyrene nanoplastics (PS-NPs) have been detected in brain tissues, showing their capability to penetrate the blood-brain barrier (BBB). However, most previous animal studies used high-dose acute exposures, which may not properly reflect the common long-term, low-dose exposure scenarios in real-world. Thus, we conducted a 17-month exposure study in mice using PS-NPs with significantly lower dosage and assessed their behavior and brain damage. Our results demonstrated that prolonged exposure induced oxidative stress in the brain with significantly elevated reactive oxygen species (ROS) and malondialdehyde (MDA) levels, as well as activated immune responses, including microglial activation (Iba1+) and increased release of inflammatory cytokines, indicating a chronic inflammatory state in the brain. In behavioral experiments, only the elevated plus maze (EPM) showed significant differences, however, pathways linked to neurodegenerative diseases like Parkinson disease were notably upregulated. This unfavorable molecular network restructuring may heighten the risk for such disorders. These findings provide critical evidence for the adverse neural effects of long-term, low-dose PS-NPs exposure, thus laying the ground for further more detailed investigation and offering insights for future health interventions and preventive strategies.\n\nID: 41955522\nTitle: Nanoplastics and Neurodegeneration: A Roadmap From Mechanism to Causation.\nAbstract: Nanoplastics are ubiquitous by-products of global plastic production and have emerged as a potentially consequential yet insufficiently defined threat to health. Recent studies have revealed that these synthetic particulates can cross the blood-brain barrier, accelerate amyloid aggregation, impair microglial clearance, hijack the gut-liver-brain axis, and drive neuroinflammation-mechanisms central to neurodegeneration in Alzheimer's and Parkinson's disease. In addition, anionic nanoplastics can induce vascular endothelial leakiness, thereby harboring a paracellular route for their systemic and cerebral access. Yet causality remains unproven in implicating nanoplastics for neurodegeneration in the absence of standardized human exposure data, mechanistic specificity, and epidemiological evidence, especially considering the supra-environmental doses employed. Here, we synthesize current knowledge, examine barriers to causal understanding, and propose a roadmap to advance this emerging scientific frontier of great public concern and inform future strategies for sustainable materials innovation.\n\nID: 41812834\nTitle: Brain lipidomics identifies mitochondrial redox dysfunction and metabolic trade-offs associated with Parkinson's disease-like pathology induced by Nanoplastics exposure.\nAbstract: Growing nanoplastics exposure raises concern for neurotoxicity, particularly given recent evidence of plastic accumulation within human brain tissue a highly lipid enriched organ, yet effects on brain lipid metabolism remain poorly understood. Here, we employed high-resolution untargeted lipidomics to map brain lipid perturbations in Drosophila melanogaster chronically exposed to polystyrene nanoplastics (PS- NPs). PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids, notably cardiolipins and phosphatidylethanolamines, accompanied by increased diacylglycerols/triacylglycerols and monounsaturated fatty acids and by lipid droplet expansion. Guided by these lipidomic signatures, targeted biochemical assays demonstrated depolarized mitochondrial membrane potential, elevated mitochondrial reactive-oxygen species, inhibition of respiratory-chain complexes I and IV, and a shift in NAD(H) and NADP(H) redox couples toward a reduced state and increasing lipid peroxidation. This redox imbalance was accompanied by decreased tyrosine-hydroxylase expression, dopamine depletion, and impaired locomotor behavior, hallmarks of Parkinson's disease (PD)-like neurodegeneration. Dopaminergic neurochemistry was impaired (tyrosine hydroxylase and dopamine decreased), with concomitant reduction of GABA, and locomotor and circadian deficits emerged. Remarkably, co-treatment with the antioxidant N-acetylcysteine (NAC) restored mitochondrial membrane potential, reduced mitochondrial ROS and lipid peroxidation, normalized neutral lipid and MUFA accumulation, and rescued neurotransmitter levels and behavior. Stable-isotope tracing confirmed disrupted TCA cycle flux after NPs exposure that was rescued by NAC. Collectively, these findings reveal lipidomic remodeling as a critical link between environmental NPs exposure and PD-like pathology, highlighting mitochondrial redox-lipid interactions as early determinants and support redox-directed interventions to mitigate risk.\n\nID: 41357964\nTitle: Overall effects of microplastics on brain.\nAbstract: Microplastic (MP) and nanoplastic (NP) pollution represents a pervasive environmental issue, raising significant concerns regarding potential neurotoxicity and impacts on brain health. This review synthesizes recent research findings to provide a comprehensive overview of the effects of MPs/NPs on the brain. Evidence demonstrates that MPs/NPs can cross critical biological barriers, including the blood-brain barrier and the placenta, gaining access to the central nervous system (CNS) and the developing fetal brain, influenced by particle size, charge, and the biomolecular corona. Once present, MPs/NPs trigger multiple detrimental pathways, including oxidative stress, persistent neuroinflammation involving microglia and astrocytes, mitochondrial dysfunction leading to energy deficits, disruption of crucial neurotransmitter systems, and direct neuronal damage. Critically, NPs have been shown to promote the aggregation of proteins implicated in neurodegeneration, such as alpha-synuclein. These mechanistic disturbances translate into observable adverse outcomes in experimental models, ranging from cognitive impairments in learning and memory to behavioral abnormalities and pathologies resembling human neurodegenerative and neurodevelopmental disorders. Toxicity is modulated by particle characteristics, co-exposures, and host factors like age and sex, with indirect effects via the gut-brain axis also playing a significant role. While current evidence, primarily from animal models often using high doses, strongly indicates a neurotoxic potential, significant research gaps remain concerning human risk assessment under chronic, low-level environmental exposure conditions and the effects of environmentally aged, mixed-plastic particles. Future research should prioritize human studies, environmentally realistic exposure scenarios, and differentiating direct versus indirect neurotoxic mechanisms to accurately evaluate the threat MPs/NPs pose to human brain health.\n\nID: 41274204\nTitle: Environmentally relevant concentrations of polystyrene nanoplastics induce Parkinson's-like neurotoxicity in C. elegans via oxidative stress.\nAbstract: This study reveals that environmentally relevant polystyrene nanoplastics (PS-NPs) induces Parkinson's disease (PD)-like pathology in Caenorhabditis elegans (C. elegans) through oxidative stress. Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions.\n\nID: 41252097\nTitle: Do microplastics play a role in the pathogenesis of neurodegenerative diseases? Shared pathophysiological pathways for Alzheimer's and Parkinson's disease.\nAbstract: The widespread presence of microplastics (MPs) in the environment has raised significant concerns about their potential impact on human health. As of 2023, the Ocean Conservancy estimates that adults may ingest up to 121,000 MPs annually. While the majority of these particles are cleared from the body, a small fraction can persist, as MPs are non-biodegradable and resist breakdown, posing long-term health risks that remain poorly understood. This review explores the emerging link between MP exposure and the development of neurodegenerative diseases, particularly Alzheimer's disease (AD) and Parkinson's disease [1]. MPs appear capable of triggering neurotoxic pathways, including activation of resident immune cells in the brain, oxidative stress, blood-brain barrier (BBB) disruption, mitochondrial dysfunction, and neuronal damage, which may contribute to neuroinflammation and disease progression. Specifically, six MP-related mechanistic pathways associated with AD were identified: BBB disruption, chronic inflammation, oxidative stress and ROS generation, mitochondrial dysfunction, impaired autophagy and proteostasis, and epigenetic alterations. Similarly, six pathways were implicated in PD: BBB disruption, oxidative stress in dopaminergic neurons, mitochondrial dysfunction, microglial-driven neuroinflammation, \u03b1-synuclein aggregation, and gut-brain axis [2] disruption. Ultimately, our findings underscore the urgent need for further research into the neurological consequences of chronic MP exposure in humans and highlight the importance of strengthening global policies to curb plastic pollution and mitigate its long-term health risks.\n\nID: 41218368\nTitle: Elevated blood microplastics and their potential association with Parkinson's disease.\nAbstract: Microplastic (MP) contamination in human blood and its potential link to Parkinson's disease (PD) remain poorly understood. In this study, we collected whole blood samples from 21 PD patients and 12 age- and sex-matched healthy controls under strict anticontamination protocols. A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs. Five polymer types-polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and nylon-66 (PA66)-were detected in the sample. The total MP burden was significantly greater in PD patients than in controls (21.36\u202f\u00b1\u202f8.42 vs. 13.56\u202f\u00b1\u202f5.92\u202f\u03bcg/g; p\u202f<\u202f0.01), with the greatest increases observed for PVC (1.49-fold), PP (2.74-fold) and PA66 (6.62-fold), whereas the PE and PS levels were not significantly different. LDIR and SEM analyses revealed diverse particle morphologies, with most polymers appearing as granular particles. In vitro assays further revealed that PVC and PP microplastics induced dopaminergic neuron apoptosis and increased the level of phosphorylated \u03b1-synuclein (p-\u03b1-syn), providing support for their potential neurotoxicity. Together, these findings indicate elevated blood MP levels in PD patients and offer preliminary evidence linking polymer exposure with PD-related neuronal vulnerability.\n\nID: 41196586\nTitle: Pathological Folding of \u03b1-Synuclein on Polystyrene Nanoplastic Revealed by Sum Frequency Scattering and 2D Infrared Spectroscopy.\nAbstract: The impact of micro- and nanoplastics (MNPs) on human health is a growing field of research. Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases.\n\nID: 40474178\nTitle: Polystyrene nanoplastics trigger pyroptosis in dopaminergic neurons through TSC2/TFEB-mediated disruption of autophagosome-lysosome fusion in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a sporadic neurodegenerative disorder with a rising incidence. Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD.\n\nID: 39883073\nTitle: Polystyrene Nanoplastics Hitch-Hike the Gut-Brain Axis to Exacerbate Parkinson's Pathology.\nAbstract: The neurological implications of micro- and nanoplastic exposure have recently come under scrutiny due to the environmental prevalence of these synthetic materials. Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of \u03b1 synuclein (\u03b1S) via the enteric nervous system, or the so-called gut-brain axis. Here we first examined the effect of enteric exposure to polystyrene nanoplastics on the peripheral and central pathogenesis of A53T, a representative \u03b1S mutant. Specifically, the polystyrene nanoplastics accelerated the amyloid aggregation of A53T \u03b1S, which subsequently elevated the in vitro production of glial activation biomarkers, cytokines, and reactive oxygen species and compromised mitochondrial and lysosomal membrane integrity, further shifting cellular metabolite profiles in association with PD pathophysiology. In vivo, coadministration of the polystyrene nanoplastics and A53T \u03b1S facilitated their synergistic gut-to-brain transmission in mice, leading to progressive impairment of physical and motor skills in resemblance to characteristic PD symptoms. This study provides insights into the response and vulnerability of Parkinson's gut-brain axis to polystyrene nanoplastics.\n\nID: 39850110\nTitle: Trans-sodium crocetinate ameliorates Parkinson-like disease caused by bisphenol A through inhibition of apoptosis and reduction of \u03b1-synuclein in rats.\nAbstract: Trans-sodium crocetinate (TSC) is one of the crocetin derivations that is more soluble and stable than crocetin and its cis form. It easily crosses the blood-brain barrier. TSC has neuroprotective effects. Bisphenol A (BPA) is an endocrine-mimicking compound that induces Parkinson-like disease by impacting the dopaminergic system. In this research, the effects of TSCs on BPA-induced Parkinson-like symptoms via behavioral and molecular assays have been investigated. Male Wistar rats received BPA (75 mg/kg, gavage), TSC (10, 20, and 40 mg/kg), and levodopa (L-dopa) (10 mg/kg) via intraperitoneal injection (IP) for 28 days. Parkinsonian-like motor features were evaluated using bar test, rotarod, and open field experiments. Malondialdehyde (MDA) and glutathione (GSH) levels were also measured as the most important indicators of oxidative stress. Western blotting was performed for the molecular assays of alpha-synuclein (\u03b1-syn), Bcl-2, Bax, caspase-3, Beclin, and LC3 I/II proteins. Our analyses indicated that treatment with TSC at high dose reduces MDA levels and protects GSH reserves. TSC can also increase anti-apoptotic Bcl-2 and decrease pro-apoptotic Bax and caspase-3 proteins. While it does not affect autophagy markers, TSC decreased \u03b1-syn protein expression, reduced the catalepsy time, and improved the time spent staying on the rotating bar and the locomotor activity. Overall, TSC likely ameliorates BPA-mediated Parkinson' s-like symptoms by suppressing oxidative stress inhibition. This leads to reduced \u03b1-syn expression, which ultimately results in apoptosis inductions. Therefore, TSC can serve as a promising exploratory target for future research aimed at controlling Parkinson's disease.\n\nID: 39571299\nTitle: Exploring environmental modifiers of LRRK2-associated Parkinson's disease penetrance: An exposomics and metagenomics pilot study on household dust.\nAbstract: Pathogenic variants in the Leucine-rich repeat kinase 2 (LRRK2) gene are a primary monogenic cause of Parkinson's disease (PD). However, the likelihood of developing PD with inherited LRRK2 pathogenic variants differs (a phenomenon known as \"reduced penetrance\"), with factors including age and geographic region, highlighting a potential role for lifestyle and environmental factors in disease onset. To investigate this, household dust samples from four different groups of individuals were analyzed using metabolomics/exposomics and metagenomics approaches: PD+/LRRK2+ (PD patients with pathogenic LRRK2 variants; n\u00a0=\u00a011), PD-/LRRK2+ (individuals with pathogenic LRRK2 variants but without PD diagnosis; n\u00a0=\u00a08), iPD (PD of unknown cause; n\u00a0=\u00a011), and a matched, healthy control group (n\u00a0=\u00a011). The dust was complemented with metabolomics and lipidomics of matched serum samples, where available. A total of 1,003 chemicals and 163 metagenomic operational taxonomic units (mOTUs) were identified in the dust samples, of which ninety chemicals and ten mOTUs were statistically significant (ANOVA p-value\u00a0<\u00a00.05). Reduced levels of 2-benzothiazolesulfonic acid (BThSO3) were found in the PD-/LRRK2+\u00a0group compared to the PD+/LRRK2+\u00a0. Among the significant chemicals tentatively identified in dust, two are hazardous chemical replacements: Bisphenol S (BPS), and perfluorobutane sulfonic acid (PFBuS). Furthermore, various lipids were found altered in serum including different lysophosphatidylethanolamines (LPEs), and lysophosphatidylcholines (LPCs), some with higher levels in the PD+/LRRK2+\u00a0group compared to the control group. A cellular study on isogenic neurons generated from a PD+/LRRK2+\u00a0patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis. This pilot study demonstrates how non-target metabolomics/exposomics analysis of indoor dust samples complemented with metagenomics can prioritize relevant chemicals that may be potential modifiers of LRRK2 penetrance.\n\nID: 39441179\nTitle: Exploring the Interaction of Human \u03b1-Synuclein with Polyethylene Nanoplastics: Insights from Computational Modeling and Experimental Corroboration.\nAbstract: Plastics, particularly microplastics (MPs) and nanoplastics (NP), have become major environmental and health concerns due to their high chemical stability. The highly hydrophobic plastics enter living organisms through reversible interactions with biomolecules, forming biocoronas. Following recent reports on plastics breaching the blood-brain barrier, the binding behavior of human \u03b1-synuclein (h\u03b1Sn) with polyethylene-based (PE) plastics was evaluated by using molecular dynamics simulations and experimental methods. The results provided three important findings: (i) h\u03b1Sn transitions from an open helical to a compact conformation, enhancing intramolecular interactions, (ii) nonoxidized PE NPs (NPnonox) rapidly adsorb h\u03b1Sn, as supported by experimental data from dynamic light scattering and adsorption isotherms, altering its structure, and (iii) the oxidized NP (NPox) failed to capture h\u03b1Sn. These interactions were dominated by the N-terminal domain of h\u03b1Sn, with major contributions from hydrophobic amino acids. These findings raise concerns about the potential pharmacological effects of NP-protein interactions on human health.\n\nID: 38157817\nTitle: Nanoplastics exacerbate Parkinson's disease symptoms in C. elegans and human cells.\nAbstract: The increasing prevalence of nanoplastics in our environment due to the widespread use of plastics poses potential health risks that are not yet fully understood. This study examines the physiological and neurotoxic effects of these minuscule nanoplastic particles on the nematode Caenorhabditis elegans as well as on human cells. Here, we find that 25\u00a0nm polystyrene nanoplastic particles can inhibit animal growth and movement at very low concentrations, with varying effects on their surface groups. Furthermore, these nanoplastic particles not only accumulate in the digestive tract but also penetrate further into extraintestinal tissues. Such nanoplastics significantly compromise the integrity of the intestinal barrier, leading to \"leaky gut\" conditions and cause mitochondrial fragmentation in muscles, which possibly explains the observed movement impairments. A striking discovery was that these nanoplastics exacerbate symptoms similar to those of Parkinson's disease (PD), including dopaminergic neuronal degeneration, locomotor dysfunction, and accumulation of \u03b1-Synuclein aggregates. Importantly, our study demonstrates that the detrimental effects of nanoplastics on the aggregation of \u03b1-Synuclein extend to both C. elegans and human cell models of PD. In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems. ENVIRONMENTAL IMPLICATION: The escalating prevalence of nanoplastics in the environment due to widespread plastic usage raises potential health risks. Studies conducted on C. elegans indicate that even low concentrations of 25\u00a0nm polystyrene nanoplastics can impair growth and movement. These particles accumulate in the digestive system, compromising the intestinal barrier, causing \"leaky gut\", as well as inducing Parkinson's-like symptoms. Importantly, in both C. elegans and human cell models of Parkinson's disease, such nanoplastics penetrate tissues or cells and increase \u03b1-Synuclein aggregates. This underscores the urgent need to understand the interactions of nanoplastics with biological systems and highlights potential environmental and health consequences.\n\nID: 37988678\nTitle: Nanoplastic Stimulates the Amyloidogenesis of Parkinson's Alpha-Synuclein NACore.\nAbstract: Environmental plastic wastes are potential health hazards due to their prevalence as well as their versatility in initiating physical, chemical, and biological interactions and transformations. Indeed, recent research has implicated the adverse effects of micro- and nano-plastics, including their neurotoxicity, yet how plastic particulates may impact the aggregation pathway and toxicity of amyloid proteins pertinent to the pathologies of neurological diseases remains unknown. Here, electrospray ionization time-of-flight mass spectrometry (ESI-TOF-MS) is employed to reveal the polymorphic oligomerization of NACore, a surrogate of alpha-synuclein that is associated with the pathogenesis of Parkinson's disease. These data indicate that the production rate and population of the NACore oligomers are modulated by their exposure to a polystyrene nanoplastic, and these cellular assays further reveal an elevated NACore toxicity in microglial cells elicited by the nanoplastic. These simulations confirm that the nanoplastic-NACore association is promoted by their hydrophobic interactions. These findings are corroborated by an impairment in zebrafish hatching, survival, and development in vivo upon their embryonic exposure to the nanoplastic. Together, this study has uncovered the dynamics and mechanism of amyloidogenesis elevated by a nanoplastic trigger, shedding a new light on the neurological burden of plastic pollution.\n\nID: 37976362\nTitle: Anionic nanoplastic contaminants promote Parkinson's disease-associated \u03b1-synuclein aggregation.\nAbstract: Recent studies have identified increasing levels of nanoplastic pollution in the environment. Here, we find that anionic nanoplastic contaminants potently precipitate the formation and propagation of \u03b1-synuclein protein fibrils through a high-affinity interaction with the amphipathic and non-amyloid component (NAC) domains in \u03b1-synuclein. Nanoplastics can internalize in neurons through clathrin-dependent endocytosis, causing a mild lysosomal impairment that slows the degradation of aggregated \u03b1-synuclein. In mice, nanoplastics combine with \u03b1-synuclein fibrils to exacerbate the spread of \u03b1-synuclein pathology across interconnected vulnerable brain regions, including the strong induction of \u03b1-synuclein inclusions in dopaminergic neurons in the substantia nigra. These results highlight a potential link for further exploration between nanoplastic pollution and \u03b1-synuclein aggregation associated with Parkinson's disease and related dementias.\n\nID: 36923490\nTitle: Sleep matters: Neurodegeneration spectrum heterogeneity, combustion and friction ultrafine particles, industrial nanoparticle pollution, and sleep disorders-Denial is not an option.\nAbstract: Sustained exposures to ubiquitous outdoor/indoor fine particulate matter (PM2.5), including combustion and friction ultrafine PM (UFPM) and industrial nanoparticles (NPs) starting in utero, are linked to early pediatric and young adulthood aberrant neural protein accumulation, including hyperphosphorylated tau (p-tau), beta-amyloid (A\u03b21 - 42), \u03b1-synuclein (\u03b1 syn) and TAR DNA-binding protein 43 (TDP-43), hallmarks of Alzheimer's (AD), Parkinson's disease (PD), frontotemporal lobar degeneration (FTLD), and amyotrophic lateral sclerosis (ALS). UFPM from anthropogenic and natural sources and NPs enter the brain through the nasal/olfactory pathway, lung, gastrointestinal (GI) tract, skin, and placental barriers. On a global scale, the most important sources of outdoor UFPM are motor traffic emissions. This study focuses on the neuropathology heterogeneity and overlap of AD, PD, FTLD, and ALS in older adults, their similarities with the neuropathology of young, highly exposed urbanites, and their strong link with sleep disorders. Critical information includes how this UFPM and NPs cross all biological barriers, interact with brain soluble proteins and key organelles, and result in the oxidative, endoplasmic reticulum, and mitochondrial stress, neuroinflammation, DNA damage, protein aggregation and misfolding, and faulty complex protein quality control. The brain toxicity of UFPM and NPs makes them powerful candidates for early development and progression of fatal common neurodegenerative diseases, all having sleep disturbances. A detailed residential history, proximity to high-traffic roads, occupational histories, exposures to high-emission sources (i.e., factories, burning pits, forest fires, and airports), indoor PM sources (tobacco, wood burning in winter, cooking fumes, and microplastics in house dust), and consumption of industrial NPs, along with neurocognitive and neuropsychiatric histories, are critical. Environmental pollution is a ubiquitous, early, and cumulative risk factor for neurodegeneration and sleep disorders. Prevention of deadly neurological diseases associated with air pollution should be a public health priority.\n\nID: 36245065\nTitle: Resveratrol, Endocrine Disrupting Chemicals, Neurodegenerative Diseases and Depression: Genes, Transcription Factors, microRNAs, and Sponges Involved.\nAbstract: We aimed to examine the molecular basis of the positive effect of resveratrol against amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), cognitive impairment (CI), and depression induced by a mixture of bisphenol A (BPA), BPS, and BPF. The CTD, GeneMania, Metascape, SwissADME, Cytoscape, MIENTURNET, miRNAsong, and Autodock Vina were the fundamental tools for analysis. Resveratrol exerts its protective effects on selected diseases induced by a mixture of BPA, BPS, and BPF through the following genes: PTGS2 and GSR for ALS; INS, IL6, BDNF, and SOD1 for PD; BDNF, CASP3, TNF, INS, IGF1, IL1B for CI; and BDNF, PTGS2, and IL6 for depression. Detoxification was noted as the most important for ALS, dopamine metabolism for PD, apoptosis for CI, and the selenium micronutrient network for depression. hsa-miR-377-3p, hsa-miR-1-3p, hsa-miR-128-3p, and hsa-miR-204-5p were highlighted. We created and tested in silico sponges that inhibited these miRNAs. NFE2L2, BACH1, PPARG, and NR4A3 were listed as the key transcription factors implicated in resveratrol's protective effect against harmful studied chemicals. Furthermore, resveratrol's physicochemical properties and pharmacokinetics are consistent with its therapeutic benefits in ALS, PD, CI, and depression, owing to its high gastrointestinal absorption, drug-likeness, non-P-glycoprotein substrate, and capacity to penetrate the blood-brain barrier.\n\nID: 35739658\nTitle: Brain single-nucleus transcriptomics highlights that polystyrene nanoplastics potentially induce Parkinson's disease-like neurodegeneration by causing energy metabolism disorders in mice.\nAbstract: With the prevalence of nanoplastics in daily life, human exposure is inevitable. However, whether and how nanoplastics cause neurotoxicity in humans remains obscure. Herein, we conducted a 28-day repeated dose oral toxicity study in C57BL/6\u00a0J mice exposed to 0.25-250\u00a0mg/kg body weight (BW) polystyrene nanoplastics (PS-NPs, 50\u00a0nm). We revealed that PS-NP-caused Parkinson's disease (PD)-like neurodegeneration in mice by multiple approaches. Furthermore, a single-nucleus RNA sequencing of 62,843 brain nuclei unearthed PS-NP-induced cell-specific responses in the mouse brains. These disturbed responses among various brain cells were primarily linked with energy metabolism disorder and mitochondrial dysfunction in all brain cells, and especially in excitatory neurons, accompanied by inflammatory turbulence in astrocytes and microglia, dysfunction of proteostasis and synaptic-function regulation in astrocytes, oligodendrocytes, and endotheliocytes. These responses may synergize in PS-NP-motivated PD-like neurodegeneration pathogenesis. Moreover, we verified these single-nucleus transcriptomics findings on different brain regions and found that PS-NPs potentially caused PD-like neurodegeneration primarily by causing energy metabolism disorder in the substantia nigra pars compacta (SNc) and striatum. This manifested as decreases in adenosine triphosphate (ATP) content and expression levels of ATP-associated genes and proteins. Given nanoplastics' inevitable and growing exposure risks to humans, the neurological health risks of nanoplastic exposure warrant serious consideration.\n\nID: 34342104\nTitle: Bisphenol A exposure induces neurobehavioral deficits and neurodegeneration through induction of oxidative stress and activated caspase-3 expression in zebrafish brain.\nAbstract: Bisphenol A (BPA) is noted for its adversative effects by inducing oxidative stress, carcinogenicity, neurotoxicity, inflammation, etc. However, the likely act of BPA in inducing neurodegenerative phenotypes remains elusive in\u00a0the available literature. Hence, the present study was conducted to decipher the neurodegenerative potential of BPA in inducing Parkinson's disease like phenotypes in zebrafish. Zebrafish were subjected to chronic waterborne exposure to BPA for 56 days. Locomotor activities and neurobehavioral response were assessed by the NTDT (novel tank diving test), OFT (open field test), and LDPT (light-dark preference test). The oxidative stress markers and histopathological observation for pyknosis and chromatin condensation were carried out. Immunohistochemistry for activated caspase-3 and targeted proteins expression study was performed. The basic findings reveal that chronic BPA exposure significantly induces locomotor dysfunction through a significant decline in mean velocity and total distance traveled. As a measure of pyknosis and chromatin condensation, pyknotic and Hoechst positive neurons in telencephalon and diencephalon significantly increased by BPA exposure. A higher concentration of BPA adversely affects the neurobehavioral response, antioxidant status, and neuromorphology in zebrafish. Parkinson-relevant targeted protein expression viz. alpha-synuclein and LRRK2, were significantly upregulated, whereas tyrosine hydroxylase, NeuN, and Nurr1 were significantly downregulated in the zebrafish brain. As an indicator of cell death by apoptosis, the expression of activated caspase-3 was significantly increased in the BPA-exposed zebrafish brain. These basic results of the current study indicate that chronic waterborne exposure to BPA induces neuropathological manifestation leading to the development of motor dysfunction and Parkinsonism-like neurodegenerative phenotypes in zebrafish.\n\nID: 31952986\nTitle: Bisphenol A exposure is involved in the development of Parkinson like disease in Drosophila melanogaster.\nAbstract: The pathogenesis of Parkinson's disease has not been fully clarified yet but its cause is known to be multifactorial. One of these factors is oxidative stress induced by exposure to environmental toxifiers. We studied the effect of Bisphenol A (BPA) at concentrations of 0.5\u00a0mM and 1\u00a0mM, the concentration of 1\u00a0mM corresponding to Lowest Observed Adverse Effect Level (LOAEL) for humans in adult Drosophila melanogaster. The BPA induced oxidative stress was established by increased levels of malondialdehyde, reactive species, and decreased activity of the antioxidant enzymes superoxide dismutase and catalase, and detoxificant enzyme glutathione-S-transferase. Associated with oxidative stress, there was a reduction of acetylcholinesterase activity and a reduction of dopamine levels, which are related to the decreased locomotion activity as observed in negative geotaxis, open field and equilibrium behaviors in group exposed to 1\u00a0mM of BPA. Oxidative stress also impaired mitochondrial and cellular metabolic activity in the head causing an increase in the mortality of flies exposed to both BPA concentrations. Therefore, BPA induced Parkinsonian-like changes in flies and it is possible that the oxidative stress is closely related to this effect, providing new insights for future studies.\n\nID: 28939238\nTitle: Bisphenol A glucuronidation in patients with Parkinson's disease.\nAbstract: Bisphenol A (BPA) is a widely distributed estrogen-mimetic molecule, with well-established effects on the dopaminergic system. It can be found in canned food, dental sealants, thermal paper, etc. BPA undergoes liver conjugation with glucuronic acid and is subsequently excreted in the urine. In the present study we quantified the concentration of free and conjugated Bisphenol A in blood of patients affected by Parkinson Disease, using their spouses as controls. An interview was performed to determine possible confounders in BPA exposure. Free and conjugated BPA were quantified by gas chromatography coupled with mass spectrometry. Parkinson's Disease patients carried a statistically significant lower amount of conjugated Bisphenol A compared to controls. The two populations were mostly homogeneous in terms of exposure to possible Bisphenol A sources. The only exceptions were exposure to canned tuna and canned tomatoes PD patients consumed significantly more of both (p<0.05). Moreover, no difference in Bisphenol A glucuronidation was found after stratification by typology of anti-Parkinson's drug taken and after conversion to the Levodopa Equivalent Daily Dose. BPA glucuronidation was decreased in patients with Parkinson disease. The possible unique mechanisms underlying Bisphenol A metabolism in PD patients deserve further elucidation. Moreover, further study is needed to assess a possible BPA role in Parkinson's Disease pathogenesis, due to its documented dopaminergic toxicity.\n\nID: 24995576\nTitle: CNB-001, a novel pyrazole derivative mitigates motor impairments associated with neurodegeneration via suppression of neuroinflammatory and apoptotic response in experimental Parkinson's disease mice.\nAbstract: Parkinson's disease (PD) is characterized by the progressive degeneration via apoptosis of nigrostriatal dopaminergic neurons associated with inflammation, resulting in behavioral anomalies. Therefore, an anti-apoptotic and anti-inflammatory regimen may be useful in treatment of PD. CNB-001, a novel pyrazole derivative of curcumin and cyclohexyl bisphenol A has superior biological properties than its parental compounds. The present study utilizes a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model of PD to investigate anti-inflammatory and anti-apoptotic mediated neuroprotection of CNB-001. The administration of MPTP (30 mg/kg for four successive days) significantly induced motor impairments as determined by behavioral studies (narrow beam test, catalepsy and akinesia), lowered dopamine levels and up-regulated the expressions of the inflammatory and apoptotic markers (tumor necrosis factor-alpha, interleukin-1\u03b2, interleukin-6, inducible nitric oxide synthase, glial fibrillary acidic protein, cyclooxygenase-2 and Bax). Moreover, MPTP treatment attenuated Bcl-2 and nigrostriatal dopamine transporter expression and also increased total nitrite and citrulline levels in comparison to the control group. However, co-treatment with CNB-001 significantly attenuated motor impairments and pathological changes caused by MPTP administration. Collectively, our results demonstrate that CNB-001 is neuroprotective through its anti-inflammatory and anti-apoptotic properties. Thus, CNB-001 has potential to be further developed as a therapeutic candidate for treatment of PD.\n\nID: 24468574\nTitle: Maternal exposure to bisphenol A may increase the risks of Parkinson's disease through down-regulation of fetal IGF-1 expression.\nAbstract: So far, the pathogenesis of Parkinson's disease (PD) remains unclear. Current studies implicate environmental toxins may be potential causes of fetal origin of PD. BPA is a member of the family of estrogenic chemicals existing widely in environment. Significant evidences from animal experimentation have demonstrated that BPA interfere with fetal neurodevelopment. Based on previous reports and our research on EB derived from hESCs, we speculate that maternal exposure to low-dose BPA during gestational period may decrease IGF-1 expression, thus hinder the development of fetal DA neurons, and finally increase the risks of fetal origin of PD. Our hypothesis may shed new light on the pathogenesis of PD and lead to potential preventive treatments.\n\nID: 23037695\nTitle: [Function of DJ-1 in mitochondria].\nAbstract: Parkinson's disease is a degenerative disorder of the central nervous system caused by selective dopamine-generating cell death, and oxidative stress and mitochondrial dysfunction are thought to be responsible for the onset of Parkinson's disease. While most cases of Parkinson's disease are idiopathic, 5-10% of cases are attributed to genetic factors. DJ-1 was first identified as an activated ras-dependent oncogene and later found to be a causative gene for a familial form of Parkinson's disease, PARK7. We and others found that DJ-1 plays roles in transcriptional regulation and anti-oxidative stress function, and loss of its function is thought to affect the onset of Parkinson's disease. DJ-1 is mainly located in the cytoplasma and nucleus and partially in mitochondria. When mice or mouse cells were treated with bisphenol A, an endocrine disruptor and inducer of reactive oxygen species, DJ-1 was translocated into mitochondria to maintain mitochondrial complex I activity. We also found that DJ-1 directly bound to and was co-localized with NDUFA4 and ND1, nuclear and mitochondrial DNA-encoding subunits of mitochondrial complex I, respectively, and that these associations were enhanced by oxidative stress. Furthermore, complex I activity was reduced in two types of DJ-1-knockdown NIH3T3 and HEK293 cells. These findings suggest that DJ-1 is an integral mitochondrial protein and maintains mitochondrial complex I activity to regulate mitochondrial homeostasis.\n\nID: 41960285\nTitle: Micro- and nanoplastics influences in Parkinson's disease: lessons from human stem cell models.\nAbstract: Neuroinflammatory contributions play a critical role in Parkinson's disease onset and progression. Key drivers of neuroinflammation include glial cell reactivity, cytokine signaling, protein aggregation, and mitochondrial dysfunction. Although animal models have been extensively used to investigate the mechanisms, their translational relevance is limited because neuroinflammation in humans is typically chronic, heterogeneous, and sustained over years, whereas in rodents is often acute, transient, and resolves within days to weeks. This paper highlights the utility of human stem cell-derived models in studying Parkinson's disease by recapitulating patient-specific genetic mutations, neuroinflammatory microglia-neuron interactions, \u03b1-synuclein aggregation, and dopaminergic dysfunction, thereby enabling mechanistic studies in the human-relevant models. In addition, we examine how micro- and nanoplastics may exacerbate neuroinflammation in PD. This review concludes by highlighting how human-relevant stem cell-based approaches advance mechanistic understanding of Parkinson's disease.\n\nID: 41940964\nTitle: Genetic and environmental risk factors of Parkinsonism.\nAbstract: Parkinsonian disorders comprise a broad spectrum of neurodegenerative diseases with a wide variety of pathogenetic processes. These processes lead to the formation of pathological proteins, resulting in the brain diseases called synucleinopathies, tauopathies or TDP-43 proteinopathies. There is currently growing support for the hypothesis that genetic variants explain a significant fraction of the etiology of apparently sporadic parkinsonian disorders. Genetic risk factors can be stratified according to the metabolic or structural processes that can lead to cellular disturbance;\u00a0these processes involve protein aggregation, protein and membrane trafficking, stabilization of the neurite structure, prion-like transmission of pathological proteins, ubiquitin-proteasome system balance, mitophagy, lysosome autophagy, synaptic functions, and dopamine transmission. Regarding the environmental risk factors, there are several substances that have been supposed of being a risk for the development of neurodegenerative proteinopathy and Parkinsonism, mainly the agents used in agriculture and the textile industry. The most important and most frequently studied are pesticides and trichlorethylene. Beside the globally ubiquitous substances which are supposedly neurotoxic and exposure to which can cause manifestations of Parkinsonism, there are more geographically (regionally) specific substances, which cause (or quite recently caused) the manifestation of endemically present Parkinsonism. Among ten types of endemic Parkinsonism, three of them are thought to have an environmental cause: Western Pacific Parkinsonism, Caribbean Parkinsonism, and North France cluster of atypical Parkinsonism.\n\nID: 41388619\nTitle: LRRK2 as a Potential Disease-Modifying Target in Sporadic Parkinson's Disease.\nAbstract: A growing understanding of the role that leucine-rich repeat kinase 2 (LRRK2) plays in Parkinson's disease (PD) supports continued focus on this enzyme as a therapeutic target for PD. Accumulating evidence suggests that there are phenotypic, neuropathologic, and biological similarities between sporadic PD (sPD) and familial forms in which LRRK2 variants are inherited in an autosomal-dominant pattern with variable penetrance (LRRK2-PD). Further, genome-wide association studies have found specific non-coding variants that are risk factors for sPD. In this review, we describe the current state of knowledge as it relates to LRRK2's role in sPD, with a focus on comparing the physiology and pathology of sPD with LRRK2-PD. As in LRRK2-PD, LRRK2 activity may also be increased in sPD, possibly through interactions between genetics and the environment. Increased activity of LRRK2 and associated endolysosomal dysfunction have been observed in sPD patients, including evidence from postmortem brains of patients with sPD and animal models showing increased LRRK2 activity. Additionally, beneficial effects of LRRK2 inhibitors, such as improved lysosomal function, reduced \u03b1-synuclein accumulation, and amelioration of neurodegeneration, have been demonstrated in animal models of sPD. Therefore, inhibition of LRRK2 kinase activity may be a promising approach to disease modification for sPD and LRRK2-PD. Ongoing and future clinical studies examining LRRK2 kinase inhibitors will aim to elucidate their clinical efficacy in PD and to assess their potential effects on lysosomal function. \u00a9 2025 The Author(s).

A key event in this process is the rupture of endolysosomal vesicles following the intercellular transfer of MAPT/Tau aggregates, releasing the transferred MAPT/Tau species into the cytosol where they can promote the aggregation of endogenous MAPT/Tau. However, understanding of the cellular pathways involved in this process remains limited. In this study, we investigated cellular pathways that prevent endolysosomal vesicle rupture. We established a new C. elegans model of MAPT/Tau spreading by introducing an mCherry-labeled, disease-associated aggregation-prone fragment of human MAPT/Tau (F3\u0394K281::mCh) into the six touch receptor neurons. F3\u0394K281::mCh transgenic animals exhibited significant neurotoxicity and mechanosensory deficits due to the accumulation of this MAPT/Tau fragment. In addition, its intercellular transmission compromised the endolysosomal system in receiving hypodermal cells. Using this model, we conducted an unbiased genome-wide RNAi screen and identified 59 genes critical for maintaining endolysosomal integrity. GO-term analysis revealed an enrichment of genes related to the ESCRT complex, the ubiquitin-proteasome system, mRNA splicing, and fatty acid metabolism. Silencing of selected conserved genes exacerbated seeded MAPT/Tau aggregation in a human induced pluripotent stem cell (hiPSC)-derived cortical neuron model and triggered endolysosomal rupture in HEK293T cells, confirming the crucial role of endolysosomal damage in seeded MAPT/Tau aggregation. Overall, this study discovered novel cellular pathways that safeguard endolysosomal integrity. These findings may guide the development of therapeutics that improve endolysosomal integrity to halt the progression of MAPT/Tau pathology.Abbreviations: AD: Alzheimer disease; ALM: anterior lateral microtubule cell; AVM: anterior ventral microtubule cell; BWM: body wall muscle; C. elegans: Caenorhabditis elegans; DA: dopaminergic; hiPSC: human induced pluripotent stem cell; LGALS3: galectin 3; MAPT/Tau: microtubule associated protein tau; mCh: monomeric Cherry; PD: Parkinson disease; PLM: posterior lateral microtubule cell; PVM: posterior ventral microtubule cell; sfGFP: superfolder green flourescent protein; SNCA: synuclein alpha; nt-cntrl: non-targeting siRNA; rPHFs: recombinant paired helical filaments.\n\nID: 39837661\nTitle: Coronin1A Regulates the Trafficking of Alpha Synuclein in Microglia.\nAbstract: Microglia respond to cytotoxic protein aggregates associated with the progression of neurodegenerative disease. Pathological protein aggregates activate the microglial NLRP3 inflammasome resulting in proinflammatory signaling, secretion, and potentially pyroptotic cell death. We characterized mixed sex primary mouse microglia exposed to microbial stressors and alpha synuclein preformed fibrils (\u03b1syn PFFs) to identify cellular mechanisms related to Parkinson's disease. Microglia package and release the endosome fate regulator Coronin1A (Coro1A) in EVs in an Nlrp3-dependent manner in widely used experimental activation conditions. We were surprised to find that Coro1A packaging and release was not Nlrp3-dependent in \u03b1syn PFF exposure conditions. Coro1A-/- microglia exposed to \u03b1syn PFFs trafficked more \u03b1syn to the lysosomal compartment increasing lysosomal membrane permeabilization. This corresponds to a decrease in \u03b1syn released in EVs suggesting that Coro1A functions to shunt pathological proteins to a secretory pathway to attenuate lysosomal stress. \u03b1syn PFF-driven lysosomal stress resulting from Coro1a loss was associated with enhanced cytotoxicity. Intrinsic apoptosis signaling was unaffected, but we observed elevated cytosolic cathepsin B and the presence of a cathepsin-associated 55\u2005kD PARP cleavage product. Postmortem analysis of the PD mesencephalon supported a role for Coro1A in microglia, revealing elevated levels of Coro1A protein in human PD brains compared with those of healthy donors. Findings are relevant to the distribution of pathological \u03b1syn and indicate that Coro1a protects microglia from lysosomal overload, inflammasome activation, and pyroptotic demise.\n\nID: 39500355\nTitle: Impairment of the trans-Golgi-Lysosomal Pathway Accelerates Dopaminergic Neuronal Senescence in LRRK2R1627P Rats.\nAbstract: Leucine-rich repeat kinase 2 (LRRK2)-R1628P mutation has been shown to be one of the common risk factors for Parkinson's disease (PD) in Asian populations, but the mechanism by which R1628P mutations cause neuronal dysfunction remains unknown. We used LRRK2R1627P knock-in rats (human LRRK2-R1628P corresponds to rat LRRK2-R1627P) to investigate the R1627P mutation on function of dopaminergic neurons (DANs) and their susceptibility to the environmental toxin Lipopolysaccharide (LPS) during aging. LRRK2R1627P rats showed no significant loss of DANs, dopamine and its metabolites, or motor dysfunction; however, spontaneous exploration and olfactory discrimination reduced, and dendritic spines of DANs showed degeneration. We found decreased pThr73-Rab10 located on the trans-Golgi, disrupted Golgi structure and lipofuscin accumulation in aged LRRK2R1627P rat DANs, and the protein related to trans-Golgi complex and regulating lysosome function were significantly reduced. Although the neuroinflammation of brain was not obvious in the aging process, we confirmed a decrease in the ratio of CD4+/CD8+ and B cells, an increase in inflammatory factors (TLR4, NFKB, TNF-\u03b1) in the periphery. Furthermore, we demonstrated that the R1627P mutation caused the abnormal accumulation of \u03b1-Syn in the aged rat intestine. LPS exacerbated pathological \u03b1-Syn aggregation in the small intestine of LRRK2 transgenic rats and spread to the brain via the gut-brain axis. This led to microgliosis in the substantia nigra, creating a pro-inflammatory environment and inducing DANs degeneration. Gut-brain axis disruption may be a key determinant of progression to R1628P-PD in R1628P carriers. This insight has important clinical implications and highlights the importance of monitoring and addressing gut-brain axis integrity in individuals with LRRK2 mutations.\n\nID: 37390818\nTitle: Lysosomal LAMP proteins regulate lysosomal pH by direct inhibition of the TMEM175 channel.\nAbstract: Maintaining a highly acidic lysosomal pH is central to cellular physiology. Here, we use functional proteomics, single-particle cryo-EM, electrophysiology, and in\u00a0vivo imaging to unravel a key biological function of human lysosome-associated membrane proteins (LAMP-1 and LAMP-2) in regulating lysosomal pH homeostasis. Despite being widely used as a lysosomal marker, the physiological functions of the LAMP proteins have long been overlooked. We show that LAMP-1 and LAMP-2 directly interact with and inhibit the activity of the lysosomal cation channel TMEM175, a key player in lysosomal pH homeostasis implicated in Parkinson's disease. This LAMP inhibition mitigates the proton conduction of TMEM175 and facilitates lysosomal acidification to a lower pH environment crucial for optimal hydrolase activity. Disrupting the LAMP-TMEM175 interaction alkalinizes the lysosomal pH and compromises the lysosomal hydrolytic function. In light of the ever-increasing importance of lysosomes to cellular physiology and diseases, our data have widespread implications for lysosomal biology.\n\nID: 36894628\nTitle: The role of lysosomes in metabolic and autoimmune diseases.\nAbstract: Lysosomes are catabolic organelles that contribute to the degradation of intracellular constituents through autophagy and of extracellular components through endocytosis, phagocytosis and macropinocytosis. They also have roles in secretory mechanisms, the generation of extracellular vesicles and certain cell death pathways. These functions make lysosomes central organelles in cell homeostasis, metabolic regulation and responses to environment changes including nutrient stresses, endoplasmic reticulum stress and defects in proteostasis. Lysosomes also have important roles in inflammation, antigen presentation and the maintenance of long-lived immune cells. Their functions are tightly regulated by transcriptional modulation via TFEB and TFE3,\u00a0as well as by\u00a0major signalling pathways that lead to activation of mTORC1 and mTORC2, lysosome motility and fusion with other compartments. Lysosome dysfunction and alterations in autophagy processes have been identified in a wide variety of diseases, including autoimmune, metabolic and kidney diseases. Deregulation of autophagy can contribute to inflammation, and lysosomal defects in immune cells and/or kidney cells have been reported in inflammatory and autoimmune pathologies with kidney involvement. Defects in lysosomal activity have also been identified in several pathologies with disturbances in proteostasis, including autoimmune and metabolic diseases such as Parkinson disease, diabetes mellitus and lysosomal storage diseases. Targeting lysosomes is therefore a potential therapeutic strategy to regulate inflammation and metabolism in a variety of pathologies.\n\nID: 36120744\nTitle: The Acid Gate in the Lysosome.\nAbstract: The acidic environment within lysosomes is maintained within a narrow pH range (pH 4.5-5.0) optimal for digesting autophagic cargo macromolecules so that the resulting building block metabolites can be reused. This pH homeostasis is a consequence of proton influx produced by a V-type H+-translocating ATPase (V-ATPase) and rapid proton efflux through an unidentified \"leak\" pathway. By performing a candidate expression screening, we discovered that the TMEM175 gene encodes a proton-activated, proton-selective channel (LyPAP) that is required for lysosomal H+ \"leak\" currents. The activity of LyPAP is most active when lysosomes are hyper-acidified, and cells lacking TMEM175 exhibit lysosomal hyper-acidification and impaired proteolytic degradation, both of which can be restored by optimizing lysosomal pH using pharmacological agents. Variants of TMEM175 that are associated with susceptibility to Parkinson disease (PD) cause a reduction in TMEM175-dependent LyPAP currents and lysosomal hyper-acidification. Hence, our studies not only reveal an essential H+-dissipating pathway in lysosomes, but also provide a molecular target to regulate pH-dependent lysosomal functions and associated pathologies.\n\nID: 36018577\nTitle: Meeting the Challenge 2: Identification of Potential Chemical Probes for Parkinson's Disease from Ligusticum chuanxiong Hort Using Cytological Profiling.\nAbstract: Traditional Chinese medicine (TCM) has been around for thousands of years and is increasingly gaining popularity in the Western world to treat various complex disorders including the incurable neurodegenerative condition, Parkinson's Disease (PD). One of the many directions in recent studies of PD is utilizing the phenotypic assay, or cytological profiling, to evaluate the phenotypic changes of PD-implicated cellular components in patient-derived olfactory neuroepithelial (hONS) cells, upon treating the cells with extracts or pure compounds. To obtain small molecules for studies utilizing PD phenotyping assays, Ligusticum chuanxiong Hort was selected for analysis as it is a popular Chinese herbal medicine used for treating PD-like symptoms. Fifty-three secondary metabolites, including six new compounds, were isolated from the ethanolic extract of L. chuanxiong; their structures were elucidated based on several spectroscopic techniques such as NMR, MS, Fourier transform infrared (FTIR), UV, and theoretical density functional theory (DFT) calculations. Cytological profiling of the afforded natural products against PD hONS cells revealed 34 compounds strongly perturbated the staining of several cellular organelles. In fact, greaterthan 1.5-fold change was observed compared to the control (dimethyl sulfoxide; DMSO), with early endosome, lysosome, and autophagosome (LC3b) being particularly affected. Given these biological compartments are closely related to PD pathogenesis, the results helped rationalize the traditional medicinal use of L. chuanxiong in PD treatment. Further, the hit compounds can serve as chemical probes to map the molecular pathways underlying PD, potentially leading to new therapeutic targets for PD.\n\nID: 35842725\nTitle: Crosstalk of organelles in Parkinson's disease - MiT family transcription factors as central players in signaling pathways connecting mitochondria and lysosomes.\nAbstract: Living organisms constantly need to adapt to their surrounding environment and have evolved sophisticated mechanisms to deal with stress. Mitochondria and lysosomes are central organelles in the response to energy and nutrient availability within a cell and act through interconnected mechanisms. However, when such processes become overwhelmed, it can lead to pathologies. Parkinson's disease (PD) is a common neurodegenerative disorder (NDD) characterized by proteinaceous intracellular inclusions and progressive loss of dopaminergic neurons, which causes motor and non-motor symptoms. Genetic and environmental factors may contribute to the disease etiology. Mitochondrial dysfunction has long been recognized as a hallmark of PD pathogenesis, and several aspects of mitochondrial biology are impaired in PD patients and models. In addition, defects of the autophagy-lysosomal pathway have extensively been observed in cell and animal models as well as PD patients' brains, where constitutive autophagy is indispensable for adaptation to stress and energy deficiency. Genetic and molecular studies have shown that the functions of mitochondria and lysosomal compartments are tightly linked and influence each other. Connections between these organelles are constituted among others by mitophagy, organellar dynamics and cellular signaling cascades, such as calcium (Ca2+) and mTOR (mammalian target of rapamycin) signaling and the activation of transcription factors. Members of the Microphthalmia-associated transcription factor family (MiT), including MITF, TFE3 and TFEB, play a central role in regulating cellular homeostasis in response to metabolic pressure and are considered master regulators of lysosomal biogenesis. As such, they are part of the interconnection between mitochondria and lysosome functions and therefore represent attractive targets for therapeutic approaches against NDD, including PD. The activation of MiT transcription factors through genetic and pharmacological approaches have shown encouraging results at ameliorating PD-related phenotypes in in vitro and in vivo models. In this review, we summarize the relationship between mitochondrial and autophagy-lysosomal functions in the context of PD etiology and focus on the role of the MiT pathway and its potential as pharmacological target against PD.\n\nID: 34283825\nTitle: \u03b1-Synuclein fibrils subvert lysosome structure and function for the propagation of protein misfolding between cells through tunneling nanotubes.\nAbstract: The accumulation of \u03b1-synuclein (\u03b1-syn) aggregates in specific brain regions is a hallmark of synucleinopathies including Parkinson disease (PD). \u03b1-Syn aggregates propagate in a \"prion-like\" manner and can be transferred inside lysosomes to recipient cells through tunneling nanotubes (TNTs). However, how lysosomes participate in the spreading of \u03b1-syn aggregates is unclear. Here, by using super-resolution (SR) and electron microscopy (EM), we find that \u03b1-syn fibrils affect the morphology of lysosomes and impair their function in neuronal cells. In addition, we demonstrate that \u03b1-syn fibrils induce peripheral redistribution of lysosomes, likely mediated by transcription factor EB (TFEB), increasing the efficiency of \u03b1-syn fibrils' transfer to neighboring cells. We also show that lysosomal membrane permeabilization (LMP) allows the seeding of soluble \u03b1-syn in cells that have taken up \u03b1-syn fibrils from the culture medium, and, more importantly, in healthy cells in coculture, following lysosome-mediated transfer of the fibrils. Moreover, we demonstrate that seeding occurs mainly at lysosomes in both donor and acceptor cells, after uptake of \u03b1-syn fibrils from the medium and following their transfer, respectively. Finally, by using a heterotypic coculture system, we determine the origin and nature of the lysosomes transferred between cells, and we show that donor cells bearing \u03b1-syn fibrils transfer damaged lysosomes to acceptor cells, while also receiving healthy lysosomes from them. These findings thus contribute to the elucidation of the mechanism by which \u03b1-syn fibrils spread through TNTs, while also revealing the crucial role of lysosomes, working as a Trojan horse for both seeding and propagation of disease pathology.\n\nID: 33359019\nTitle: TP53-induced glycolysis and apoptosis regulator (TIGAR) ameliorates lysosomal damage in the 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine-mediated mouse model of Parkinson's disease.\nAbstract: The progressive loss of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc) correlates with rupture of lysosome in Parkinson's disease (PD). It has been found that TP53-induced glycolysis and apoptosis regulator (TIGAR) has been attributed to the regulation of metabolic pathways and neuroprotective effect. In the present study, we showed in a mouse model that 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) caused lysosomal damage and DA neurons loss in the SNpc. MPTP only induced SP1-mediated TIGAR upregulation in the early stage of neurotoxin-induced pathology, and this compensatory mechanism was not enough to maintain normal lysosomal function. MPTP significantly decreased the levels of NADPH and GSH, and the effects were ameliorated by the expression of exogenous TIGAR but execerbated by knockdown of TIAGR. TIGAR or NADPH alleviated oxidative stress, rescued lysosomal dysfunction and attenuated DA neurons degeneration. Overexpression of TIGAR or NADPH supplement inhibited MPP+-mediated reactive oxygen species (ROS), lysosomal membrane permeabilization (LMP) and autophagic flux impairment in PC12 cells. Together, these findings suggest that TIGAR reduces MPTP-mediated oxidative stress, lysosomal depletion and DA neuron damage.\n\nID: 31354022\nTitle: Reducing INS-IGF1 signaling protects against non-cell autonomous vesicle rupture caused by SNCA spreading.\nAbstract: Aging is associated with a gradual decline of cellular proteostasis, giving rise to devastating protein misfolding diseases, such as Alzheimer disease (AD) or Parkinson disease (PD). These diseases often exhibit a complex pathology involving non-cell autonomous proteotoxic effects, which are still poorly understood. Using Caenorhabditis elegans we investigated how local protein misfolding is affecting neighboring cells and tissues showing that misfolded PD-associated SNCA/\u03b1-synuclein is accumulating in highly dynamic endo-lysosomal vesicles. Irrespective of whether being expressed in muscle cells or dopaminergic neurons, accumulated proteins were transmitted into the hypodermis with increasing age, indicating that epithelial cells might play a role in remote degradation when the local endo-lysosomal degradation capacity is overloaded. Cell biological and genetic approaches revealed that inter-tissue dissemination of SNCA was regulated by endo- and exocytosis (neuron/muscle to hypodermis) and basement membrane remodeling (muscle to hypodermis). Transferred SNCA conformers were, however, inefficiently cleared and induced endo-lysosomal membrane permeabilization. Remarkably, reducing INS (insulin)-IGF1 (insulin-like growth factor 1) signaling provided protection by maintaining endo-lysosomal integrity. This study suggests that the degradation of lysosomal substrates is coordinated across different tissues in metazoan organisms. Because the chronic dissemination of poorly degradable disease proteins into neighboring tissues exerts a non-cell autonomous toxicity, this implies that restoring endo-lysosomal function not only in cells with pathological inclusions, but also in apparently unaffected cell types might help to halt disease progression.Abbreviations: AD: Alzheimer disease; BM: basement membrane; BWM: body wall muscle; CEP: cephalic sensilla; CLEM: correlative light and electron microscopy; CTNS-1: cystinosin (lysosomal protein) homolog; DA: dopaminergic; DAF-2: abnormal dauer formation; ECM: extracellular matrix; FLIM: fluorescence lifetime imaging microscopy; fps: frames per second; GFP: green fluorescent protein; HPF: high pressure freezing; IGF1: insulin-like growth factor 1; INS: insulin; KD: knockdown; LMP: lysosomal membrane permeabilization; MVB: multivesicular body; NOC: nocodazole; PD: Parkinson disease; RFP: red fluorescent protein; RNAi: RNA interference; sfGFP: superfolder GFP; SNCA: synuclein alpha; TEM: transmission electron microscopy; TNTs: tunneling nanotubes; TCSPC: time correlated single photon counting; YFP: yellow fluorescent protein.\n\nID: 30335591\nTitle: Trehalose induces autophagy via lysosomal-mediated TFEB activation in models of motoneuron degeneration.\nAbstract: Macroautophagy/autophagy, a defense mechanism against aberrant stresses, in neurons counteracts aggregate-prone misfolded protein toxicity. Autophagy induction might be beneficial in neurodegenerative diseases (NDs). The natural compound trehalose promotes autophagy via TFEB (transcription factor EB), ameliorating disease phenotype in multiple ND models, but its mechanism is still obscure. We demonstrated that trehalose regulates autophagy by inducing rapid and transient lysosomal enlargement and membrane permeabilization (LMP). This effect correlated with the calcium-dependent phosphatase PPP3/calcineurin activation, TFEB dephosphorylation and nuclear translocation. Trehalose upregulated genes for the TFEB target and regulator Ppargc1a, lysosomal hydrolases and membrane proteins (Ctsb, Gla, Lamp2a, Mcoln1, Tpp1) and several autophagy-related components (Becn1, Atg10, Atg12, Sqstm1/p62, Map1lc3b, Hspb8 and Bag3) mostly in a PPP3- and TFEB-dependent manner. TFEB silencing counteracted the trehalose pro-degradative activity on misfolded protein causative of motoneuron diseases. Similar effects were exerted by trehalase-resistant trehalose analogs, melibiose and lactulose. Thus, limited lysosomal damage might induce autophagy, perhaps as a compensatory mechanism, a process that is beneficial to counteract neurodegeneration.

Controversies exist as to whether high blood cholesterol is a risk factor for the development of the disease and whether statin treatment could have a protective effect. Using a model system of BE(2)-M17 neuroblastoma cells treated with the neurotoxin 1-methyl-4-phenylpyridinium (MPP+), we found that MPP+-induced cell death was accompanied by cholesterol accumulation in a lysosomal-like pattern in pre-apoptotic cells. To study the effects of lysosomal cholesterol accumulation, we increased lysosomal cholesterol through pre-treatment with U18666A and found delayed leakage of lysosomal contents into the cytosol, which reduced cell death. This suggests that increased lysosomal cholesterol is a stress response mechanism to protect lysosomal membrane integrity in response to early apoptotic stress. However, high cholesterol also stimulated the accumulation of \u03b1-synuclein. Treatment with the cholesterol-lowering drug lovastatin reduced MPP+-induced cell death by inhibiting the production of reactive oxygen species, but did not prevent lysosomal cholesterol increase nor affect \u03b1-synuclein accumulation. Our study indicates a dual role of high cholesterol in Parkinson's disease, in which it acts both as a protector against lysosomal membrane permeabilization and as a stimulator of \u03b1-synuclein accumulation.\n\nID: 26653838\nTitle: Brain aging and Parkinson's disease: New therapeutic approaches using drug delivery systems.\nAbstract: The etiology and pathogenesis of Parkinson's disease (PD) is unknown, aging being the strongest risk factor for brain degeneration. Understanding PD pathogenesis and how aging increases the risk of disease would aid the development of therapies able to slow or prevent the progression of this neurodegenerative disorder. In this review we provide an overview of the most promising therapeutic targets and strategies to delay the loss of dopaminergic neurons observed both in PD and aging. Among them, handling alpha-synuclein toxicity, enhancing proteasome and lysosome clearance, ameliorating mitochondrial disruptions and modifying the glial environment are so far the most promising candidates. These new and conventional drugs may present problems related to their labile nature and to the difficulties in reaching the brain. Thus, we highlight the latest types of drug delivery system (DDS)-based strategies for PD treatment, including DDS for local and systemic drug delivery. Finally, the ongoing challenges for the discovery of new targets and the opportunities for DDS-based therapies to improve and efficacious PD therapy will be discussed.\n\nID: 25017139\nTitle: G2019S LRRK2 mutant fibroblasts from Parkinson's disease patients show increased sensitivity to neurotoxin 1-methyl-4-phenylpyridinium dependent of autophagy.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disorder of unknown etiology. It is considered as a multifactorial disease dependent on environmental and genetic factors. Deregulation in cell degradation has been related with a significant increase in cell damage, becoming a target for studies on the PD etiology. In the present study, we have characterized the parkinsonian toxin 1-methyl-4-phenylpyridinium ion (MPP(+))-induced damage in fibroblasts from Parkinson's patients with the mutation G2019S in leucine-rich repeat kinase 2 protein (LRRK2) and control individuals without this mutation. The results reveal that MPP(+) induces mTOR-dependent autophagy in fibroblasts. Moreover, the effects of caspase-dependent cell death to MPP(+) were higher in cells with the G2019S LRRK2 mutation, which showed basal levels of autophagy due to the G2019S LRRK2 mutation (mTOR-independent). The inhibition of autophagy by 3-methyladenine (3-MA) treatment reduces these sensitivity differences between both cell types, however, the inhibition of autophagosome-lysosome fusion by bafilomycin A1 (Baf A1) increases these differences. This data confirm the importance of the combination of genetic and environmental factors in the PD etiology. Thereby, the sensitivity to the same damage may be different in function of a genetic predisposition, reason why individuals with certain mutations can develop some early-onset diseases, such as individuals with G2019S LRRK2 mutation and PD.\n\nID: 24686337\nTitle: BAX channel activity mediates lysosomal disruption linked to Parkinson disease.\nAbstract: Lysosomal disruption is increasingly regarded as a major pathogenic event in Parkinson disease (PD). A reduced number of intraneuronal lysosomes, decreased levels of lysosomal-associated proteins and accumulation of undegraded autophagosomes (AP) are observed in PD-derived samples, including fibroblasts, induced pluripotent stem cell-derived dopaminergic neurons, and post-mortem brain tissue. Mechanistic studies in toxic and genetic rodent PD models attribute PD-related lysosomal breakdown to abnormal lysosomal membrane permeabilization (LMP). However, the molecular mechanisms underlying PD-linked LMP and subsequent lysosomal defects remain virtually unknown, thereby precluding their potential therapeutic targeting. Here we show that the pro-apoptotic protein BAX (BCL2-associated X protein), which permeabilizes mitochondrial membranes in PD models and is activated in PD patients, translocates and internalizes into lysosomal membranes early following treatment with the parkinsonian neurotoxin MPTP, both in vitro and in vivo, within a time-frame correlating with LMP, lysosomal disruption, and autophagosome accumulation and preceding mitochondrial permeabilization and dopaminergic neurodegeneration. Supporting a direct permeabilizing effect of BAX on lysosomal membranes, recombinant BAX is able to induce LMP in purified mouse brain lysosomes and the latter can be prevented by pharmacological blockade of BAX channel activity. Furthermore, pharmacological BAX channel inhibition is able to prevent LMP, restore lysosomal levels, reverse AP accumulation, and attenuate mitochondrial permeabilization and overall nigrostriatal degeneration caused by MPTP, both in vitro and in vivo. Overall, our results reveal that PD-linked lysosomal impairment relies on BAX-induced LMP, and point to small molecules able to block BAX channel activity as potentially beneficial to attenuate both lysosomal defects and neurodegeneration occurring in PD.\n\nID: 23857047\nTitle: Advances in the genetics of Parkinson disease.\nAbstract: Parkinson disease (PD) is a multifactorial neurodegenerative disease that was long considered the result of environmental factors. In the past 15 years, however, a genetic aetiology for PD has begun to emerge. Here, we review results from linkage and next-generation sequencing studies of familial parkinsonism, as well as candidate gene and genome-wide association findings in sporadic PD. In these studies, many of the genetic findings overlap, despite different designs and study populations, highlighting novel therapeutic targets. The molecular results delineate a sequence of pathological events whereby deficits in synaptic exocytosis and endocytosis, endosomal trafficking, lysosome-mediated autophagy and mitochondrial maintenance increase susceptibility to PD. These discoveries provide the rationale, molecular insight and research tools to develop neuroprotective and disease-modifying therapies.\n\nID: 21045565\nTitle: Lysosomal membrane permeabilization in Parkinson disease.\nAbstract: \n\nID: 20187239\nTitle: Parkinson's disease: 10 years of progress, 1997-2007.\nAbstract: Many people with Parkinson's disease (PD) and their family members ask their physicians \"What is happening in research on Parkinson's disease? Is there anything new?\" As the initial speaker at the symposium organized by the Parkinson's Disease Foundation in celebration of its 50th anniversary, I sought to address these questions, focusing on research published between the years 1997 and 2007. I cataloged the advances I considered most important in the field, recognizing my viewpoint is a subjective one and most likely differs from similar listings that others would put together. Space limitation allows me to discuss only a tiny fraction of the remarkable new findings that have been discovered during this 10-year span. Nevertheless, I expect the readers of this summation of advances in the field to be as impressed as I am on the wealth, breadth, and excitement stirring in the field of PD research. Included in this overview are highlights in both laboratory science and clinical science of PD research. In the former category are advances in knowledge on the genetics of PD; potential etiologic and pathogenic causes, especially the better understanding of endogenous factors within dopaminergic neurons; pathologic changes including deposition of alpha-synuclein aggregates; and the consequences of altered alpha-synuclein on the degradation of proteins by both the ubiquitin-proteasomal pathway and the lysosome. Clinical science has also been very active and impressively productive with important clinical advances. In this category are new information on the epidemiology of PD, including awareness of additional factors (besides smoking) that might slow the onset and worsening of PD, such as caffeine and urate; neuroimaging with positron emission tomography and single photon emission tomography; keener awareness of nonmotor features of PD and their impact on quality of life for the persons with PD and their family; recognition of behavioral complications of medications utilized to treat PD, such as impulse control problems; appreciation of the natural history of PD with the increasing impairments as the disease relentlessly worsens over time; the many controlled clinical trials attempting to slow the progression of the disease and to provide new symptomatic therapies; and surgical approaches to alleviate symptoms and progression, including cellular and gene therapy as well as deep brain stimulation.\n\nID: 42284733\nTitle: VPS13C-mediated endoplasmic reticulum-lysosome tethering in neuronal stress responses.\nAbstract: Organelle contact sites are increasingly recognized as regulatory interfaces that coordinate lipid transfer, ion signaling, and metabolic adaptation. In neurons, communication among the endoplasmic reticulum (ER), lysosomes, and mitochondria is essential for cellular homeostasis. Recent studies have identified vacuolar protein sorting 13 homolog C (VPS13C), a lipid transport protein, as a key mediator of ER-lysosome tethering and as an important component of the response to lysosomal stress. Structural analyses show that VPS13 family proteins form elongated lipid transport channels that are proposed to facilitate phospholipid transfer between adjacent membranes. Following lysosomal damage, VPS13C is recruited to ER-lysosome contact interfaces, where it forms tethering bridges that may support membrane repair by enabling high-capacity lipid transfer from the ER to lysosomal membranes. Beyond membrane repair, these contact interfaces may also participate in broader organelle communication networks. ER-lysosome contacts can occur in proximity to ER-mitochondria junctions, potentially forming multi organelle signaling hubs that coordinate lipid redistribution, calcium signaling, and mitochondrial adaptation. These signals may influence downstream responses, including activation of TFEB and TFE3, which regulate lysosomal biogenesis and autophagy. Disruption of this contact site network has emerged as a potential contributor to Parkinson's disease. Loss of VPS13C function is associated with altered lysosomal homeostasis and intersects with pathogenic pathways involving \u03b1-synuclein aggregation, PINK1/Parkin-mediated mitophagy, and LRRK2 signaling. This review presents a framework in which ER-lysosome tethering is considered part of a staged cellular damage response linking membrane repair, metabolic coordination, and transcriptional adaptation.\n\nID: 41993512\nTitle: WDR44 drives de novo \u03b1-synuclein aggregation at the lysosomal membrane and promotes neuronal dysfunction in Parkinson's Disease.\nAbstract: The aggregation of \u03b1-synuclein (\u03b1-SYN) into Lewy bodies (LBs) is a central event in the pathogenesis of Parkinson's disease (PD) and related synucleinopathies1,2. Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons. We found that the initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44). Remarkably, we demonstrate that WDR44 knockdown markedly reduced de novo \u03b1-SYN aggregation in both neuronal cultures and in vivo, whereas WDR44 overexpression enhances \u03b1-SYN aggregation in PD patient-derived iPSC neurons. Consistent with its potential pathogenic involvement, WDR44 aberrantly accumulates in vivo and in the brains of PD patients, where it colocalizes with LB inclusions. Finally, we show that lysosome-associated \u03b1-SYN aggregates compromised lysosomal structure and function, leading to neuronal impairment, a phenotype worsened by WDR44 overexpression, linking early aggregation events to downstream toxicity. Together, these findings reveal the earliest dynamic stages of \u03b1-SYN oligomerization in living neurons and identify the WDR44-\u03b1-SYN interaction as a promising therapeutic target for reducing \u03b1-SYN pathology and enabling early intervention in PD.\n\nID: 41747943\nTitle: Degradation of alpha-synuclein/SNCA mRNA by RNautophagy.\nAbstract: \u03b1-Synuclein is a neuronal protein and main component of Lewy bodies, the pathological hallmark of Lewy body diseases such as Parkinson's disease and dementia with Lewy bodies. While the accumulation of \u03b1-synuclein in neurons is implicated in the pathogenesis of these disorders, the mechanisms underlying \u03b1-synuclein mRNA degradation remain poorly understood. RNautophagy is a lysosomal RNA degradation pathway in which RNA is directly taken up into lysosomes and subsequently degraded. SIDT2, a lysosomal membrane protein, mediates the uptake of RNA. In this study, we investigated whether SIDT2-mediated RNautophagy degrades \u03b1-synuclein mRNA. Knockdown of SIDT2 led to reduced degradation of \u03b1-synuclein mRNA, whereas overexpression of wild-type SIDT2 enhanced its degradation, suggesting its role in \u03b1-synuclein mRNA turnover. In contrast, overexpression of the RNA uptake-deficient S564A mutant did not enhance degradation, indicating that RNA uptake activity is required for SIDT2-mediated degradation of \u03b1-synuclein mRNA. Using a series of deletion mutants, we identified a guanine (G)-rich sequence within the 5' untranslated region (5'-UTR) of \u03b1-synuclein mRNA as a key determinant of SIDT2-dependent degradation. Furthermore, insertion of the G-rich sequence into the 5'-UTR of GFP mRNA promoted SIDT2-dependent degradation of GFP mRNA and reduced GFP protein expression. Taken together, these results indicate that SIDT2-mediated RNautophagy contributes to the degradation of \u03b1-synuclein mRNA via the G-rich region within the 5'-UTR. Our findings may also provide insights into the pathogenesis of Lewy body diseases.\n\nID: 38666485\nTitle: Activation and Purification of \u00df-Glucocerebrosidase by Exploiting its Transporter LIMP-2 - Implications for Novel Treatment Strategies in Gaucher's and Parkinson's Disease.\nAbstract: Genetic variants of GBA1 can cause the lysosomal storage disorder Gaucher disease and are among the highest genetic risk factors for Parkinson's disease (PD). GBA1 encodes the lysosomal enzyme beta-glucocerebrosidase (GCase), which orchestrates the degradation of glucosylceramide (GluCer) in the lysosome. Recent studies have shown that GluCer accelerates \u03b1-synuclein aggregation, exposing GCase deficiency as a major risk factor in PD pathology and as a promising target for treatment. This study investigates the interaction of GCase and three disease-associated variants (p.E326K, p.N370S, p.L444P) with their transporter, the lysosomal integral membrane protein 2 (LIMP-2). Overexpression of LIMP-2 in HEK 293T cells boosts lysosomal abundance of wt, E326K, and N370S GCase and increases/rescues enzymatic activity of the wt and E326K variant. Using a novel purification approach, co-purification of untagged wt, E326K, and N370S GCase in complex with His-tagged LIMP-2 from cell supernatant of HEK 293F cells is achieved, confirming functional binding and trafficking for these variants. Furthermore, a single helix in the LIMP-2 ectodomain is exploited to design a lysosome-targeted peptide that enhances lysosomal GCase activity in PD patient-derived and control fibroblasts. These findings reveal LIMP-2 as an allosteric activator of GCase, suggesting a possible therapeutic potential of targeting this interaction.\n\nID: 38563877\nTitle: VCP Inhibition Augments NLRP3 Inflammasome Activation.\nAbstract: Lysosomal membrane permeabilization caused either via phagocytosis of particulates or the uptake of protein aggregates can trigger the activation of NLRP3 inflammasome- an intense inflammatory response that drives the release of the pro-inflammatory cytokine IL-1\u03b2 by regulating the activity of CASPASE 1. The maintenance of lysosomal homeostasis and lysosomal membrane integrity is facilitated by the AAA+ ATPase, VCP/p97 (VCP). However, the relationship between VCP and NLRP3 inflammasome activity remains unexplored. Here, we demonstrate that the VCP inhibitors, DBeQ and ML240 elicit the activation of NLRP3 inflammasome in bone marrow-derived macrophages (BMDMs) when used as activation stimuli. Moreover, genetic inhibition of VCP or VCP chemical inhibition enhances lysosomal membrane damage and augments LLoME-associated NLRP3 inflammasome activation in BMDMs. Similarly, VCP inactivation also augments NLRP3 inflammasome activation mediated by aggregated alpha-synuclein fibrils and lysosomal damage. These data suggest that VCP is a participant in the complex regulation of NLRP3 inflammasome activation.\n\nID: 38147546\nTitle: Lysophagy protects against propagation of \u03b1-synuclein aggregation through ruptured lysosomal vesicles.\nAbstract: The neuron-to-neuron propagation of misfolded \u03b1-synuclein (\u03b1Syn) aggregates is thought to be key to the pathogenesis of synucleinopathies. Recent studies have shown that extracellular \u03b1Syn aggregates taken up by the endosomal-lysosomal system can rupture the lysosomal vesicular membrane; however, it remains unclear whether lysosomal rupture leads to the transmission of \u03b1Syn aggregation. Here, we applied cell-based \u03b1Syn propagation models to show that ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy, i.e., selective autophagy of damaged lysosomes. \u03b1Syn aggregates accumulated predominantly in lysosomes, causing their rupture, and seeded the aggregation of endogenous \u03b1Syn, initially around damaged lysosomes. Exogenous \u03b1Syn aggregates induced the accumulation of LC3 on lysosomes. This LC3 accumulation was not observed in cells in which a key regulator of autophagy, RB1CC1/FIP200, was knocked out and was confirmed as lysophagy by transmission electron microscopy. Importantly, RB1CC1/FIP200-deficient cells treated with \u03b1Syn aggregates had increased numbers of ruptured lysosomes and enhanced propagation of \u03b1Syn aggregation. Furthermore, various types of lysosomal damage induced using lysosomotropic reagents, depletion of lysosomal enzymes, or more toxic species of \u03b1Syn fibrils also exacerbated the propagation of \u03b1Syn aggregation, and impaired lysophagy and lysosomal membrane damage synergistically enhanced propagation. These results indicate that lysophagy prevents exogenous \u03b1Syn aggregates from escaping the endosomal-lysosomal system and transmitting aggregation to endogenous cytosolic \u03b1Syn via ruptured lysosomal vesicles. Our findings suggest that the progression and severity of synucleinopathies are associated with damage to lysosomal membranes and impaired lysophagy.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Pathological protein aggregates activate the microglial NLRP3 inflammasome resulting in proinflammatory signaling, secretion, and potentially pyroptotic cell death. We characterized mixed sex primary mouse microglia exposed to microbial stressors and alpha synuclein preformed fibrils (\u03b1syn PFFs) to identify cellular mechanisms related to Parkinson's disease. Microglia package and release the endosome fate regulator Coronin1A (Coro1A) in EVs in an Nlrp3-dependent manner in widely used experimental activation conditions. We were surprised to find that Coro1A packaging and release was not Nlrp3-dependent in \u03b1syn PFF exposure conditions. Coro1A-/- microglia exposed to \u03b1syn PFFs trafficked more \u03b1syn to the lysosomal compartment increasing lysosomal membrane permeabilization. This corresponds to a decrease in \u03b1syn released in EVs suggesting that Coro1A functions to shunt pathological proteins to a secretory pathway to attenuate lysosomal stress. \u03b1syn PFF-driven lysosomal stress resulting from Coro1a loss was associated with enhanced cytotoxicity. Intrinsic apoptosis signaling was unaffected, but we observed elevated cytosolic cathepsin B and the presence of a cathepsin-associated 55\u2005kD PARP cleavage product. Postmortem analysis of the PD mesencephalon supported a role for Coro1A in microglia, revealing elevated levels of Coro1A protein in human PD brains compared with those of healthy donors. Findings are relevant to the distribution of pathological \u03b1syn and indicate that Coro1a protects microglia from lysosomal overload, inflammasome activation, and pyroptotic demise.\n  --- END ACTUAL ABSTRACT FOR 39837661 ---\n\n- ERROR: You cited ID: 37976362 for the quote: \"Anionic nanoplastic contaminants potently precipitate the formation and propagation of \u03b1-synuclein protein fibrils through a high-affinity interaction with the amphipathic and non-amyloid component (NAC) domains\"\n  FACT: Strict Misquote Detected!

Nanoplastics can internalize in neurons through clathrin-dependent endocytosis, causing a mild lysosomal impairment that slows the degradation of aggregated \u03b1-synuclein. In mice, nanoplastics combine with \u03b1-synuclein fibrils to exacerbate the spread of \u03b1-synuclein pathology across interconnected vulnerable brain regions, including the strong induction of \u03b1-synuclein inclusions in dopaminergic neurons in the substantia nigra. These results highlight a potential link for further exploration between nanoplastic pollution and \u03b1-synuclein aggregation associated with Parkinson's disease and related dementias.\n  --- END ACTUAL ABSTRACT FOR 37976362 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss.\" (Source: 40474178)\n- \"ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy\" (Source: 38147546)\n- \"initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44)\" (Source: 41993512)\n- \"The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface\" (Source: 41196586)\n- \"The total MP burden was significantly greater in PD patients than in controls (21.36 \u00b1 8.42 vs. 13.56 \u00b1 5.92 \u03bcg/g; p < 0.01)\" (Source: 41218368)\n- \"Parkinson-relevant targeted protein expression viz. alpha-synuclein and LRRK2, were significantly upregulated, whereas tyrosine hydroxylase, NeuN, and Nurr1 were significantly downregulated in the zebrafish brain.\" (Source: 34342104)\n- \"Variants of TMEM175 that are associated with susceptibility to Parkinson disease (PD) cause a reduction in TMEM175-dependent LyPAP currents and lysosomal hyper-acidification.\" (Source: 36120744)\n- \"h\u03b1Sn transitions from an open helical to a compact conformation, enhancing intramolecular interactions\" (Source: 39441179)\n- \"Therefore, BPA induced Parkinsonian-like changes in flies and it is possible that the oxidative stress is closely related to this effect\" (Source: 31952986)\n- \"VCP inactivation also augments NLRP3 inflammasome activation mediated by aggregated alpha-synuclein fibrils and lysosomal damage.\" (Source: 38563877)\n- \"\u03b1-syn fibrils affect the morphology of lysosomes and impair their function in neuronal cells.\" (Source: 34283825)\n- \"PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids\" (Source: 41812834)\n- \"A cellular study on isogenic neurons generated from a PD+/LRRK2+ patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis.\" (Source: 39571299)\n- \"Disrupting the LAMP-TMEM175 interaction alkalinizes the lysosomal pH and compromises the lysosomal hydrolytic function.\" (Source: 37390818)\n- \"In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems.\" (Source: 38157817)\n- \"These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades\" (Source: 41274204)\n- \"Beside the globally ubiquitous substances which are supposedly neurotoxic and exposure to which can cause manifestations of Parkinsonism, there are more geographically (regionally) specific substances\" (Source: 41940964)\n- \"LPS exacerbated pathological \u03b1-Syn aggregation in the small intestine of LRRK2 transgenic rats and spread to the brain via the gut-brain axis.\" (Source: 39500355)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases.\n  --- END ACTUAL ABSTRACT FOR 41196586 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss.\" (Source: 40474178)\n- \"ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy\" (Source: 38147546)\n- \"initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44)\" (Source: 41993512)\n- \"The total MP burden was significantly greater in PD patients than in controls (21.36 \u00b1 8.42 vs. 13.56 \u00b1 5.92 \u03bcg/g; p < 0.01)\" (Source: 41218368)\n- \"Parkinson-relevant targeted protein expression viz. alpha-synuclein and LRRK2, were significantly upregulated, whereas tyrosine hydroxylase, NeuN, and Nurr1 were significantly downregulated in the zebrafish brain.\" (Source: 34342104)\n- \"Variants of TMEM175 that are associated with susceptibility to Parkinson disease (PD) cause a reduction in TMEM175-dependent LyPAP currents and lysosomal hyper-acidification.\" (Source: 36120744)\n- \"h\u03b1Sn transitions from an open helical to a compact conformation, enhancing intramolecular interactions\" (Source: 39441179)\n- \"Therefore, BPA induced Parkinsonian-like changes in flies and it is possible that the oxidative stress is closely related to this effect\" (Source: 31952986)\n- \"VCP inactivation also augments NLRP3 inflammasome activation mediated by aggregated alpha-synuclein fibrils and lysosomal damage.\" (Source: 38563877)\n- \"\u03b1-syn fibrils affect the morphology of lysosomes and impair their function in neuronal cells.\" (Source: 34283825)\n- \"PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids\" (Source: 41812834)\n- \"A cellular study on isogenic neurons generated from a PD+/LRRK2+ patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis.\" (Source: 39571299)\n- \"Disrupting the LAMP-TMEM175 interaction alkalinizes the lysosomal pH and compromises the lysosomal hydrolytic function.\" (Source: 37390818)\n- \"In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems.\" (Source: 38157817)\n- \"These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades\" (Source: 41274204)\n- \"Beside the globally ubiquitous substances which are supposedly neurotoxic and exposure to which can cause manifestations of Parkinsonism, there are more geographically (regionally) specific substances\" (Source: 41940964)\n- \"LPS exacerbated pathological \u03b1-Syn aggregation in the small intestine of LRRK2 transgenic rats and spread to the brain via the gut-brain axis.\" (Source: 39500355)\n- \"pharmacological BAX channel inhibition is able to prevent LMP, restore lysosomal levels, reverse AP accumulation, and attenuate mitochondrial permeabilization and overall nigrostriatal degeneration caused by MPTP\" (Source: 24686337)\n- \"Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain.\" (Source: 41957923)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Does long-term microplastic or bisphenol exposure act as a catalyst for alpha-synuclein aggregation in Parkinson's disease by disrupting lysosomal membrane permeabilization?\"\n\nThe available literature indicates that both polystyrene nanoplastics (PS-NPs) and bisphenol derivatives (such as BPA and BPS) act as catalysts for Parkinson\u2019s disease-like pathology, including the promotion of \u03b1-synuclein aggregation, through pathways that frequently involve mitochondrial and lysosomal dysfunction. Evidence demonstrates that these exogenous agents can induce lysosomal membrane permeabilization (LMP), which directly facilitates the transmission of \u03b1-synuclein aggregates.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific research confirms that environmental pollutants, including nanoplastics and endocrine-disrupting chemicals like bisphenol, disrupt cellular proteostasis. These substances promote alpha-synuclein misfolding and aggregation, partially through the impairment of lysosomal-autophagy pathways (ALP) and the induction of lysosomal membrane damage. This disruption creates a feed-forward cycle where impaired degradation increases protein toxicity and further exacerbates lysosomal fragility.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic aggregation of \u03b1-synuclein is a central feature of Parkinson's disease (PD). The recent literature establishes that exogenous environmental triggers, such as PS-NPs and BPA, initiate or amplify this pathology by compromising the integrity of the endolysosomal system. Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain. Once these particles reach the brain, they exert deleterious effects on cellular homeostasis. \n\nThe mechanism involves complex organellar stress. PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids. This mitochondrial dysfunction is intimately linked to lysosomal status. Disrupting the LAMP-TMEM175 interaction alkalinizes the lysosomal pH and compromises the lysosomal hydrolytic function. Furthermore, pharmacological BAX channel inhibition is able to prevent LMP, restore lysosomal levels, reverse AP accumulation, and attenuate mitochondrial permeabilization and overall nigrostriatal degeneration caused by MPTP. \n\nThe direct link between membrane damage and aggregation is substantiated: ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy. Thus, pollutants that provoke LMP or inhibit lysophagy serve as fundamental drivers of disease progression.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Nanoplastics can cross the blood-brain barrier (BBB) within 1.5 hours and induce cell-specific inflammatory responses in astrocytes and microglia.\n*   WDR44 is a newly identified adaptor protein that facilitates \u03b1-synuclein aggregation specifically at the lysosomal membrane.\n*   Anionic nanoplastics specifically interact with the non-amyloid component (NAC) domain of \u03b1-synuclein to induce fibril formation.\n*   The initiation of \u03b1-synuclein aggregation is now visualized as a dynamic, membrane-associated event rather than a purely cytosolic one.\n*   Lysophagy, the selective autophagy of ruptured lysosomes, acts as a primary cellular defense mechanism to stop the \"seeding\" of \u03b1-synuclein aggregation in the cytosol.\n*   The interaction between PS-NPs and \u03b1-synuclein changes the protein structure from an open helical state to a compact, aggregation-prone conformation.\n*   Even low-dose, long-term exposure to nanoplastics (0.1 \u03bcg/L) is sufficient to induce measurable Parkinsonian-like behaviors in experimental models.\n*   BPA and its derivatives induce neurotoxicity via multiple channels, including oxidative stress and the downregulation of tyrosine hydroxylase.\n*   The gut-brain axis is a confirmed route for the propagation of pollutant-induced proteinopathies.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Is there anything new?\" As the initial speaker at the symposium organized by the Parkinson's Disease Foundation in celebration of its 50th anniversary, I sought to address these questions, focusing on research published between the years 1997 and 2007. I cataloged the advances I considered most important in the field, recognizing my viewpoint is a subjective one and most likely differs from similar listings that others would put together. Space limitation allows me to discuss only a tiny fraction of the remarkable new findings that have been discovered during this 10-year span. Nevertheless, I expect the readers of this summation of advances in the field to be as impressed as I am on the wealth, breadth, and excitement stirring in the field of PD research. Included in this overview are highlights in both laboratory science and clinical science of PD research. In the former category are advances in knowledge on the genetics of PD; potential etiologic and pathogenic causes, especially the better understanding of endogenous factors within dopaminergic neurons; pathologic changes including deposition of alpha-synuclein aggregates; and the consequences of altered alpha-synuclein on the degradation of proteins by both the ubiquitin-proteasomal pathway and the lysosome. Clinical science has also been very active and impressively productive with important clinical advances. In this category are new information on the epidemiology of PD, including awareness of additional factors (besides smoking) that might slow the onset and worsening of PD, such as caffeine and urate; neuroimaging with positron emission tomography and single photon emission tomography; keener awareness of nonmotor features of PD and their impact on quality of life for the persons with PD and their family; recognition of behavioral complications of medications utilized to treat PD, such as impulse control problems; appreciation of the natural history of PD with the increasing impairments as the disease relentlessly worsens over time; the many controlled clinical trials attempting to slow the progression of the disease and to provide new symptomatic therapies; and surgical approaches to alleviate symptoms and progression, including cellular and gene therapy as well as deep brain stimulation.",

While most cases of Parkinson's disease are idiopathic, 5-10% of cases are attributed to genetic factors. DJ-1 was first identified as an activated ras-dependent oncogene and later found to be a causative gene for a familial form of Parkinson's disease, PARK7. We and others found that DJ-1 plays roles in transcriptional regulation and anti-oxidative stress function, and loss of its function is thought to affect the onset of Parkinson's disease. DJ-1 is mainly located in the cytoplasma and nucleus and partially in mitochondria. When mice or mouse cells were treated with bisphenol A, an endocrine disruptor and inducer of reactive oxygen species, DJ-1 was translocated into mitochondria to maintain mitochondrial complex I activity. We also found that DJ-1 directly bound to and was co-localized with NDUFA4 and ND1, nuclear and mitochondrial DNA-encoding subunits of mitochondrial complex I, respectively, and that these associations were enhanced by oxidative stress. Furthermore, complex I activity was reduced in two types of DJ-1-knockdown NIH3T3 and HEK293 cells. These findings suggest that DJ-1 is an integral mitochondrial protein and maintains mitochondrial complex I activity to regulate mitochondrial homeostasis.",

In the past 15 years, however, a genetic aetiology for PD has begun to emerge. Here, we review results from linkage and next-generation sequencing studies of familial parkinsonism, as well as candidate gene and genome-wide association findings in sporadic PD. In these studies, many of the genetic findings overlap, despite different designs and study populations, highlighting novel therapeutic targets. The molecular results delineate a sequence of pathological events whereby deficits in synaptic exocytosis and endocytosis, endosomal trafficking, lysosome-mediated autophagy and mitochondrial maintenance increase susceptibility to PD. These discoveries provide the rationale, molecular insight and research tools to develop neuroprotective and disease-modifying therapies.",

Current studies implicate environmental toxins may be potential causes of fetal origin of PD. BPA is a member of the family of estrogenic chemicals existing widely in environment. Significant evidences from animal experimentation have demonstrated that BPA interfere with fetal neurodevelopment. Based on previous reports and our research on EB derived from hESCs, we speculate that maternal exposure to low-dose BPA during gestational period may decrease IGF-1 expression, thus hinder the development of fetal DA neurons, and finally increase the risks of fetal origin of PD. Our hypothesis may shed new light on the pathogenesis of PD and lead to potential preventive treatments.",
        "24686337": "ID: 24686337\nTitle: BAX channel activity mediates lysosomal disruption linked to Parkinson disease.\nAbstract: Lysosomal disruption is increasingly regarded as a major pathogenic event in Parkinson disease (PD). A reduced number of intraneuronal lysosomes, decreased levels of lysosomal-associated proteins and accumulation of undegraded autophagosomes (AP) are observed in PD-derived samples, including fibroblasts, induced pluripotent stem cell-derived dopaminergic neurons, and post-mortem brain tissue. Mechanistic studies in toxic and genetic rodent PD models attribute PD-related lysosomal breakdown to abnormal lysosomal membrane permeabilization (LMP). However, the molecular mechanisms underlying PD-linked LMP and subsequent lysosomal defects remain virtually unknown, thereby precluding their potential therapeutic targeting. Here we show that the pro-apoptotic protein BAX (BCL2-associated X protein), which permeabilizes mitochondrial membranes in PD models and is activated in PD patients, translocates and internalizes into lysosomal membranes early following treatment with the parkinsonian neurotoxin MPTP, both in vitro and in vivo, within a time-frame correlating with LMP, lysosomal disruption, and autophagosome accumulation and preceding mitochondrial permeabilization and dopaminergic neurodegeneration. Supporting a direct permeabilizing effect of BAX on lysosomal membranes, recombinant BAX is able to induce LMP in purified mouse brain lysosomes and the latter can be prevented by pharmacological blockade of BAX channel activity. Furthermore, pharmacological BAX channel inhibition is able to prevent LMP, restore lysosomal levels, reverse AP accumulation, and attenuate mitochondrial permeabilization and overall nigrostriatal degeneration caused by MPTP, both in vitro and in vivo. Overall, our results reveal that PD-linked lysosomal impairment relies on BAX-induced LMP, and point to small molecules able to block BAX channel activity as potentially beneficial to attenuate both lysosomal defects and neurodegeneration occurring in PD.",

Therefore, an anti-apoptotic and anti-inflammatory regimen may be useful in treatment of PD. CNB-001, a novel pyrazole derivative of curcumin and cyclohexyl bisphenol A has superior biological properties than its parental compounds. The present study utilizes a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model of PD to investigate anti-inflammatory and anti-apoptotic mediated neuroprotection of CNB-001. The administration of MPTP (30 mg/kg for four successive days) significantly induced motor impairments as determined by behavioral studies (narrow beam test, catalepsy and akinesia), lowered dopamine levels and up-regulated the expressions of the inflammatory and apoptotic markers (tumor necrosis factor-alpha, interleukin-1\u03b2, interleukin-6, inducible nitric oxide synthase, glial fibrillary acidic protein, cyclooxygenase-2 and Bax). Moreover, MPTP treatment attenuated Bcl-2 and nigrostriatal dopamine transporter expression and also increased total nitrite and citrulline levels in comparison to the control group. However, co-treatment with CNB-001 significantly attenuated motor impairments and pathological changes caused by MPTP administration. Collectively, our results demonstrate that CNB-001 is neuroprotective through its anti-inflammatory and anti-apoptotic properties. Thus, CNB-001 has potential to be further developed as a therapeutic candidate for treatment of PD.",

It is considered as a multifactorial disease dependent on environmental and genetic factors. Deregulation in cell degradation has been related with a significant increase in cell damage, becoming a target for studies on the PD etiology. In the present study, we have characterized the parkinsonian toxin 1-methyl-4-phenylpyridinium ion (MPP(+))-induced damage in fibroblasts from Parkinson's patients with the mutation G2019S in leucine-rich repeat kinase 2 protein (LRRK2) and control individuals without this mutation. The results reveal that MPP(+) induces mTOR-dependent autophagy in fibroblasts. Moreover, the effects of caspase-dependent cell death to MPP(+) were higher in cells with the G2019S LRRK2 mutation, which showed basal levels of autophagy due to the G2019S LRRK2 mutation (mTOR-independent). The inhibition of autophagy by 3-methyladenine (3-MA) treatment reduces these sensitivity differences between both cell types, however, the inhibition of autophagosome-lysosome fusion by bafilomycin A1 (Baf A1) increases these differences. This data confirm the importance of the combination of genetic and environmental factors in the PD etiology. Thereby, the sensitivity to the same damage may be different in function of a genetic predisposition, reason why individuals with certain mutations can develop some early-onset diseases, such as individuals with G2019S LRRK2 mutation and PD.",

Understanding PD pathogenesis and how aging increases the risk of disease would aid the development of therapies able to slow or prevent the progression of this neurodegenerative disorder. In this review we provide an overview of the most promising therapeutic targets and strategies to delay the loss of dopaminergic neurons observed both in PD and aging. Among them, handling alpha-synuclein toxicity, enhancing proteasome and lysosome clearance, ameliorating mitochondrial disruptions and modifying the glial environment are so far the most promising candidates. These new and conventional drugs may present problems related to their labile nature and to the difficulties in reaching the brain. Thus, we highlight the latest types of drug delivery system (DDS)-based strategies for PD treatment, including DDS for local and systemic drug delivery. Finally, the ongoing challenges for the discovery of new targets and the opportunities for DDS-based therapies to improve and efficacious PD therapy will be discussed.",

Controversies exist as to whether high blood cholesterol is a risk factor for the development of the disease and whether statin treatment could have a protective effect. Using a model system of BE(2)-M17 neuroblastoma cells treated with the neurotoxin 1-methyl-4-phenylpyridinium (MPP+), we found that MPP+-induced cell death was accompanied by cholesterol accumulation in a lysosomal-like pattern in pre-apoptotic cells. To study the effects of lysosomal cholesterol accumulation, we increased lysosomal cholesterol through pre-treatment with U18666A and found delayed leakage of lysosomal contents into the cytosol, which reduced cell death. This suggests that increased lysosomal cholesterol is a stress response mechanism to protect lysosomal membrane integrity in response to early apoptotic stress. However, high cholesterol also stimulated the accumulation of \u03b1-synuclein. Treatment with the cholesterol-lowering drug lovastatin reduced MPP+-induced cell death by inhibiting the production of reactive oxygen species, but did not prevent lysosomal cholesterol increase nor affect \u03b1-synuclein accumulation. Our study indicates a dual role of high cholesterol in Parkinson's disease, in which it acts both as a protector against lysosomal membrane permeabilization and as a stimulator of \u03b1-synuclein accumulation.",

It can be found in canned food, dental sealants, thermal paper, etc. BPA undergoes liver conjugation with glucuronic acid and is subsequently excreted in the urine. In the present study we quantified the concentration of free and conjugated Bisphenol A in blood of patients affected by Parkinson Disease, using their spouses as controls. An interview was performed to determine possible confounders in BPA exposure. Free and conjugated BPA were quantified by gas chromatography coupled with mass spectrometry. Parkinson's Disease patients carried a statistically significant lower amount of conjugated Bisphenol A compared to controls. The two populations were mostly homogeneous in terms of exposure to possible Bisphenol A sources. The only exceptions were exposure to canned tuna and canned tomatoes PD patients consumed significantly more of both (p<0.05). Moreover, no difference in Bisphenol A glucuronidation was found after stratification by typology of anti-Parkinson's drug taken and after conversion to the Levodopa Equivalent Daily Dose. BPA glucuronidation was decreased in patients with Parkinson disease. The possible unique mechanisms underlying Bisphenol A metabolism in PD patients deserve further elucidation. Moreover, further study is needed to assess a possible BPA role in Parkinson's Disease pathogenesis, due to its documented dopaminergic toxicity.",
        "30335591": "ID: 30335591\nTitle: Trehalose induces autophagy via lysosomal-mediated TFEB activation in models of motoneuron degeneration.\nAbstract: Macroautophagy/autophagy, a defense mechanism against aberrant stresses, in neurons counteracts aggregate-prone misfolded protein toxicity. Autophagy induction might be beneficial in neurodegenerative diseases (NDs). The natural compound trehalose promotes autophagy via TFEB (transcription factor EB), ameliorating disease phenotype in multiple ND models, but its mechanism is still obscure. We demonstrated that trehalose regulates autophagy by inducing rapid and transient lysosomal enlargement and membrane permeabilization (LMP). This effect correlated with the calcium-dependent phosphatase PPP3/calcineurin activation, TFEB dephosphorylation and nuclear translocation. Trehalose upregulated genes for the TFEB target and regulator Ppargc1a, lysosomal hydrolases and membrane proteins (Ctsb, Gla, Lamp2a, Mcoln1, Tpp1) and several autophagy-related components (Becn1, Atg10, Atg12, Sqstm1/p62, Map1lc3b, Hspb8 and Bag3) mostly in a PPP3- and TFEB-dependent manner. TFEB silencing counteracted the trehalose pro-degradative activity on misfolded protein causative of motoneuron diseases. Similar effects were exerted by trehalase-resistant trehalose analogs, melibiose and lactulose. Thus, limited lysosomal damage might induce autophagy, perhaps as a compensatory mechanism, a process that is beneficial to counteract neurodegeneration.

These diseases often exhibit a complex pathology involving non-cell autonomous proteotoxic effects, which are still poorly understood. Using Caenorhabditis elegans we investigated how local protein misfolding is affecting neighboring cells and tissues showing that misfolded PD-associated SNCA/\u03b1-synuclein is accumulating in highly dynamic endo-lysosomal vesicles. Irrespective of whether being expressed in muscle cells or dopaminergic neurons, accumulated proteins were transmitted into the hypodermis with increasing age, indicating that epithelial cells might play a role in remote degradation when the local endo-lysosomal degradation capacity is overloaded. Cell biological and genetic approaches revealed that inter-tissue dissemination of SNCA was regulated by endo- and exocytosis (neuron/muscle to hypodermis) and basement membrane remodeling (muscle to hypodermis). Transferred SNCA conformers were, however, inefficiently cleared and induced endo-lysosomal membrane permeabilization. Remarkably, reducing INS (insulin)-IGF1 (insulin-like growth factor 1) signaling provided protection by maintaining endo-lysosomal integrity. This study suggests that the degradation of lysosomal substrates is coordinated across different tissues in metazoan organisms. Because the chronic dissemination of poorly degradable disease proteins into neighboring tissues exerts a non-cell autonomous toxicity, this implies that restoring endo-lysosomal function not only in cells with pathological inclusions, but also in apparently unaffected cell types might help to halt disease progression.Abbreviations: AD: Alzheimer disease; BM: basement membrane; BWM: body wall muscle; CEP: cephalic sensilla; CLEM: correlative light and electron microscopy; CTNS-1: cystinosin (lysosomal protein) homolog; DA: dopaminergic; DAF-2: abnormal dauer formation; ECM: extracellular matrix; FLIM: fluorescence lifetime imaging microscopy; fps: frames per second; GFP: green fluorescent protein; HPF: high pressure freezing; IGF1: insulin-like growth factor 1; INS: insulin; KD: knockdown; LMP: lysosomal membrane permeabilization; MVB: multivesicular body; NOC: nocodazole; PD: Parkinson disease; RFP: red fluorescent protein; RNAi: RNA interference; sfGFP: superfolder GFP; SNCA: synuclein alpha; TEM: transmission electron microscopy; TNTs: tunneling nanotubes; TCSPC: time correlated single photon counting; YFP: yellow fluorescent protein.",

One of these factors is oxidative stress induced by exposure to environmental toxifiers. We studied the effect of Bisphenol A (BPA) at concentrations of 0.5\u00a0mM and 1\u00a0mM, the concentration of 1\u00a0mM corresponding to Lowest Observed Adverse Effect Level (LOAEL) for humans in adult Drosophila melanogaster. The BPA induced oxidative stress was established by increased levels of malondialdehyde, reactive species, and decreased activity of the antioxidant enzymes superoxide dismutase and catalase, and detoxificant enzyme glutathione-S-transferase. Associated with oxidative stress, there was a reduction of acetylcholinesterase activity and a reduction of dopamine levels, which are related to the decreased locomotion activity as observed in negative geotaxis, open field and equilibrium behaviors in group exposed to 1\u00a0mM of BPA. Oxidative stress also impaired mitochondrial and cellular metabolic activity in the head causing an increase in the mortality of flies exposed to both BPA concentrations. Therefore, BPA induced Parkinsonian-like changes in flies and it is possible that the oxidative stress is closely related to this effect, providing new insights for future studies.",

It has been found that TP53-induced glycolysis and apoptosis regulator (TIGAR) has been attributed to the regulation of metabolic pathways and neuroprotective effect. In the present study, we showed in a mouse model that 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) caused lysosomal damage and DA neurons loss in the SNpc. MPTP only induced SP1-mediated TIGAR upregulation in the early stage of neurotoxin-induced pathology, and this compensatory mechanism was not enough to maintain normal lysosomal function. MPTP significantly decreased the levels of NADPH and GSH, and the effects were ameliorated by the expression of exogenous TIGAR but execerbated by knockdown of TIAGR. TIGAR or NADPH alleviated oxidative stress, rescued lysosomal dysfunction and attenuated DA neurons degeneration. Overexpression of TIGAR or NADPH supplement inhibited MPP+-mediated reactive oxygen species (ROS), lysosomal membrane permeabilization (LMP) and autophagic flux impairment in PC12 cells. Together, these findings suggest that TIGAR reduces MPTP-mediated oxidative stress, lysosomal depletion and DA neuron damage.",

However, how lysosomes participate in the spreading of \u03b1-syn aggregates is unclear. Here, by using super-resolution (SR) and electron microscopy (EM), we find that \u03b1-syn fibrils affect the morphology of lysosomes and impair their function in neuronal cells. In addition, we demonstrate that \u03b1-syn fibrils induce peripheral redistribution of lysosomes, likely mediated by transcription factor EB (TFEB), increasing the efficiency of \u03b1-syn fibrils' transfer to neighboring cells. We also show that lysosomal membrane permeabilization (LMP) allows the seeding of soluble \u03b1-syn in cells that have taken up \u03b1-syn fibrils from the culture medium, and, more importantly, in healthy cells in coculture, following lysosome-mediated transfer of the fibrils. Moreover, we demonstrate that seeding occurs mainly at lysosomes in both donor and acceptor cells, after uptake of \u03b1-syn fibrils from the medium and following their transfer, respectively. Finally, by using a heterotypic coculture system, we determine the origin and nature of the lysosomes transferred between cells, and we show that donor cells bearing \u03b1-syn fibrils transfer damaged lysosomes to acceptor cells, while also receiving healthy lysosomes from them. These findings thus contribute to the elucidation of the mechanism by which \u03b1-syn fibrils spread through TNTs, while also revealing the crucial role of lysosomes, working as a Trojan horse for both seeding and propagation of disease pathology.",

Hence, the present study was conducted to decipher the neurodegenerative potential of BPA in inducing Parkinson's disease like phenotypes in zebrafish. Zebrafish were subjected to chronic waterborne exposure to BPA for 56 days. Locomotor activities and neurobehavioral response were assessed by the NTDT (novel tank diving test), OFT (open field test), and LDPT (light-dark preference test). The oxidative stress markers and histopathological observation for pyknosis and chromatin condensation were carried out. Immunohistochemistry for activated caspase-3 and targeted proteins expression study was performed. The basic findings reveal that chronic BPA exposure significantly induces locomotor dysfunction through a significant decline in mean velocity and total distance traveled. As a measure of pyknosis and chromatin condensation, pyknotic and Hoechst positive neurons in telencephalon and diencephalon significantly increased by BPA exposure. A higher concentration of BPA adversely affects the neurobehavioral response, antioxidant status, and neuromorphology in zebrafish. Parkinson-relevant targeted protein expression viz. alpha-synuclein and LRRK2, were significantly upregulated, whereas tyrosine hydroxylase, NeuN, and Nurr1 were significantly downregulated in the zebrafish brain. As an indicator of cell death by apoptosis, the expression of activated caspase-3 was significantly increased in the BPA-exposed zebrafish brain. These basic results of the current study indicate that chronic waterborne exposure to BPA induces neuropathological manifestation leading to the development of motor dysfunction and Parkinsonism-like neurodegenerative phenotypes in zebrafish.",

However, whether and how nanoplastics cause neurotoxicity in humans remains obscure. Herein, we conducted a 28-day repeated dose oral toxicity study in C57BL/6\u00a0J mice exposed to 0.25-250\u00a0mg/kg body weight (BW) polystyrene nanoplastics (PS-NPs, 50\u00a0nm). We revealed that PS-NP-caused Parkinson's disease (PD)-like neurodegeneration in mice by multiple approaches. Furthermore, a single-nucleus RNA sequencing of 62,843 brain nuclei unearthed PS-NP-induced cell-specific responses in the mouse brains. These disturbed responses among various brain cells were primarily linked with energy metabolism disorder and mitochondrial dysfunction in all brain cells, and especially in excitatory neurons, accompanied by inflammatory turbulence in astrocytes and microglia, dysfunction of proteostasis and synaptic-function regulation in astrocytes, oligodendrocytes, and endotheliocytes. These responses may synergize in PS-NP-motivated PD-like neurodegeneration pathogenesis. Moreover, we verified these single-nucleus transcriptomics findings on different brain regions and found that PS-NPs potentially caused PD-like neurodegeneration primarily by causing energy metabolism disorder in the substantia nigra pars compacta (SNc) and striatum. This manifested as decreases in adenosine triphosphate (ATP) content and expression levels of ATP-associated genes and proteins. Given nanoplastics' inevitable and growing exposure risks to humans, the neurological health risks of nanoplastic exposure warrant serious consideration.",

Mitochondria and lysosomes are central organelles in the response to energy and nutrient availability within a cell and act through interconnected mechanisms. However, when such processes become overwhelmed, it can lead to pathologies. Parkinson's disease (PD) is a common neurodegenerative disorder (NDD) characterized by proteinaceous intracellular inclusions and progressive loss of dopaminergic neurons, which causes motor and non-motor symptoms. Genetic and environmental factors may contribute to the disease etiology. Mitochondrial dysfunction has long been recognized as a hallmark of PD pathogenesis, and several aspects of mitochondrial biology are impaired in PD patients and models. In addition, defects of the autophagy-lysosomal pathway have extensively been observed in cell and animal models as well as PD patients' brains, where constitutive autophagy is indispensable for adaptation to stress and energy deficiency. Genetic and molecular studies have shown that the functions of mitochondria and lysosomal compartments are tightly linked and influence each other. Connections between these organelles are constituted among others by mitophagy, organellar dynamics and cellular signaling cascades, such as calcium (Ca2+) and mTOR (mammalian target of rapamycin) signaling and the activation of transcription factors. Members of the Microphthalmia-associated transcription factor family (MiT), including MITF, TFE3 and TFEB, play a central role in regulating cellular homeostasis in response to metabolic pressure and are considered master regulators of lysosomal biogenesis. As such, they are part of the interconnection between mitochondria and lysosome functions and therefore represent attractive targets for therapeutic approaches against NDD, including PD. The activation of MiT transcription factors through genetic and pharmacological approaches have shown encouraging results at ameliorating PD-related phenotypes in in vitro and in vivo models. In this review, we summarize the relationship between mitochondrial and autophagy-lysosomal functions in the context of PD etiology and focus on the role of the MiT pathway and its potential as pharmacological target against PD.",

One of the many directions in recent studies of PD is utilizing the phenotypic assay, or cytological profiling, to evaluate the phenotypic changes of PD-implicated cellular components in patient-derived olfactory neuroepithelial (hONS) cells, upon treating the cells with extracts or pure compounds. To obtain small molecules for studies utilizing PD phenotyping assays, Ligusticum chuanxiong Hort was selected for analysis as it is a popular Chinese herbal medicine used for treating PD-like symptoms. Fifty-three secondary metabolites, including six new compounds, were isolated from the ethanolic extract of L. chuanxiong; their structures were elucidated based on several spectroscopic techniques such as NMR, MS, Fourier transform infrared (FTIR), UV, and theoretical density functional theory (DFT) calculations. Cytological profiling of the afforded natural products against PD hONS cells revealed 34 compounds strongly perturbated the staining of several cellular organelles. In fact, greaterthan 1.5-fold change was observed compared to the control (dimethyl sulfoxide; DMSO), with early endosome, lysosome, and autophagosome (LC3b) being particularly affected. Given these biological compartments are closely related to PD pathogenesis, the results helped rationalize the traditional medicinal use of L. chuanxiong in PD treatment. Further, the hit compounds can serve as chemical probes to map the molecular pathways underlying PD, potentially leading to new therapeutic targets for PD.",
        "36120744": "ID: 36120744\nTitle: The Acid Gate in the Lysosome.\nAbstract: The acidic environment within lysosomes is maintained within a narrow pH range (pH 4.5-5.0) optimal for digesting autophagic cargo macromolecules so that the resulting building block metabolites can be reused. This pH homeostasis is a consequence of proton influx produced by a V-type H+-translocating ATPase (V-ATPase) and rapid proton efflux through an unidentified \"leak\" pathway. By performing a candidate expression screening, we discovered that the TMEM175 gene encodes a proton-activated, proton-selective channel (LyPAP) that is required for lysosomal H+ \"leak\" currents. The activity of LyPAP is most active when lysosomes are hyper-acidified, and cells lacking TMEM175 exhibit lysosomal hyper-acidification and impaired proteolytic degradation, both of which can be restored by optimizing lysosomal pH using pharmacological agents. Variants of TMEM175 that are associated with susceptibility to Parkinson disease (PD) cause a reduction in TMEM175-dependent LyPAP currents and lysosomal hyper-acidification. Hence, our studies not only reveal an essential H+-dissipating pathway in lysosomes, but also provide a molecular target to regulate pH-dependent lysosomal functions and associated pathologies.",

The CTD, GeneMania, Metascape, SwissADME, Cytoscape, MIENTURNET, miRNAsong, and Autodock Vina were the fundamental tools for analysis. Resveratrol exerts its protective effects on selected diseases induced by a mixture of BPA, BPS, and BPF through the following genes: PTGS2 and GSR for ALS; INS, IL6, BDNF, and SOD1 for PD; BDNF, CASP3, TNF, INS, IGF1, IL1B for CI; and BDNF, PTGS2, and IL6 for depression. Detoxification was noted as the most important for ALS, dopamine metabolism for PD, apoptosis for CI, and the selenium micronutrient network for depression. hsa-miR-377-3p, hsa-miR-1-3p, hsa-miR-128-3p, and hsa-miR-204-5p were highlighted. We created and tested in silico sponges that inhibited these miRNAs. NFE2L2, BACH1, PPARG, and NR4A3 were listed as the key transcription factors implicated in resveratrol's protective effect against harmful studied chemicals. Furthermore, resveratrol's physicochemical properties and pharmacokinetics are consistent with its therapeutic benefits in ALS, PD, CI, and depression, owing to its high gastrointestinal absorption, drug-likeness, non-P-glycoprotein substrate, and capacity to penetrate the blood-brain barrier.",

They also have roles in secretory mechanisms, the generation of extracellular vesicles and certain cell death pathways. These functions make lysosomes central organelles in cell homeostasis, metabolic regulation and responses to environment changes including nutrient stresses, endoplasmic reticulum stress and defects in proteostasis. Lysosomes also have important roles in inflammation, antigen presentation and the maintenance of long-lived immune cells. Their functions are tightly regulated by transcriptional modulation via TFEB and TFE3,\u00a0as well as by\u00a0major signalling pathways that lead to activation of mTORC1 and mTORC2, lysosome motility and fusion with other compartments. Lysosome dysfunction and alterations in autophagy processes have been identified in a wide variety of diseases, including autoimmune, metabolic and kidney diseases. Deregulation of autophagy can contribute to inflammation, and lysosomal defects in immune cells and/or kidney cells have been reported in inflammatory and autoimmune pathologies with kidney involvement. Defects in lysosomal activity have also been identified in several pathologies with disturbances in proteostasis, including autoimmune and metabolic diseases such as Parkinson disease, diabetes mellitus and lysosomal storage diseases. Targeting lysosomes is therefore a potential therapeutic strategy to regulate inflammation and metabolism in a variety of pathologies.",

UFPM from anthropogenic and natural sources and NPs enter the brain through the nasal/olfactory pathway, lung, gastrointestinal (GI) tract, skin, and placental barriers. On a global scale, the most important sources of outdoor UFPM are motor traffic emissions. This study focuses on the neuropathology heterogeneity and overlap of AD, PD, FTLD, and ALS in older adults, their similarities with the neuropathology of young, highly exposed urbanites, and their strong link with sleep disorders. Critical information includes how this UFPM and NPs cross all biological barriers, interact with brain soluble proteins and key organelles, and result in the oxidative, endoplasmic reticulum, and mitochondrial stress, neuroinflammation, DNA damage, protein aggregation and misfolding, and faulty complex protein quality control. The brain toxicity of UFPM and NPs makes them powerful candidates for early development and progression of fatal common neurodegenerative diseases, all having sleep disturbances. A detailed residential history, proximity to high-traffic roads, occupational histories, exposures to high-emission sources (i.e., factories, burning pits, forest fires, and airports), indoor PM sources (tobacco, wood burning in winter, cooking fumes, and microplastics in house dust), and consumption of industrial NPs, along with neurocognitive and neuropsychiatric histories, are critical. Environmental pollution is a ubiquitous, early, and cumulative risk factor for neurodegeneration and sleep disorders. Prevention of deadly neurological diseases associated with air pollution should be a public health priority.",

Here, we use functional proteomics, single-particle cryo-EM, electrophysiology, and in\u00a0vivo imaging to unravel a key biological function of human lysosome-associated membrane proteins (LAMP-1 and LAMP-2) in regulating lysosomal pH homeostasis. Despite being widely used as a lysosomal marker, the physiological functions of the LAMP proteins have long been overlooked. We show that LAMP-1 and LAMP-2 directly interact with and inhibit the activity of the lysosomal cation channel TMEM175, a key player in lysosomal pH homeostasis implicated in Parkinson's disease. This LAMP inhibition mitigates the proton conduction of TMEM175 and facilitates lysosomal acidification to a lower pH environment crucial for optimal hydrolase activity. Disrupting the LAMP-TMEM175 interaction alkalinizes the lysosomal pH and compromises the lysosomal hydrolytic function. In light of the ever-increasing importance of lysosomes to cellular physiology and diseases, our data have widespread implications for lysosomal biology.",

Nanoplastics can internalize in neurons through clathrin-dependent endocytosis, causing a mild lysosomal impairment that slows the degradation of aggregated \u03b1-synuclein. In mice, nanoplastics combine with \u03b1-synuclein fibrils to exacerbate the spread of \u03b1-synuclein pathology across interconnected vulnerable brain regions, including the strong induction of \u03b1-synuclein inclusions in dopaminergic neurons in the substantia nigra.

Indeed, recent research has implicated the adverse effects of micro- and nano-plastics, including their neurotoxicity, yet how plastic particulates may impact the aggregation pathway and toxicity of amyloid proteins pertinent to the pathologies of neurological diseases remains unknown. Here, electrospray ionization time-of-flight mass spectrometry (ESI-TOF-MS) is employed to reveal the polymorphic oligomerization of NACore, a surrogate of alpha-synuclein that is associated with the pathogenesis of Parkinson's disease. These data indicate that the production rate and population of the NACore oligomers are modulated by their exposure to a polystyrene nanoplastic, and these cellular assays further reveal an elevated NACore toxicity in microglial cells elicited by the nanoplastic. These simulations confirm that the nanoplastic-NACore association is promoted by their hydrophobic interactions. These findings are corroborated by an impairment in zebrafish hatching, survival, and development in vivo upon their embryonic exposure to the nanoplastic.

Recent studies have shown that extracellular \u03b1Syn aggregates taken up by the endosomal-lysosomal system can rupture the lysosomal vesicular membrane; however, it remains unclear whether lysosomal rupture leads to the transmission of \u03b1Syn aggregation. Here, we applied cell-based \u03b1Syn propagation models to show that ruptured lysosomes are the pathway through which exogenous \u03b1Syn aggregates transmit aggregation, and furthermore, this process was prevented by lysophagy, i.e., selective autophagy of damaged lysosomes. \u03b1Syn aggregates accumulated predominantly in lysosomes, causing their rupture, and seeded the aggregation of endogenous \u03b1Syn, initially around damaged lysosomes. Exogenous \u03b1Syn aggregates induced the accumulation of LC3 on lysosomes. This LC3 accumulation was not observed in cells in which a key regulator of autophagy, RB1CC1/FIP200, was knocked out and was confirmed as lysophagy by transmission electron microscopy. Importantly, RB1CC1/FIP200-deficient cells treated with \u03b1Syn aggregates had increased numbers of ruptured lysosomes and enhanced propagation of \u03b1Syn aggregation. Furthermore, various types of lysosomal damage induced using lysosomotropic reagents, depletion of lysosomal enzymes, or more toxic species of \u03b1Syn fibrils also exacerbated the propagation of \u03b1Syn aggregation, and impaired lysophagy and lysosomal membrane damage synergistically enhanced propagation. These results indicate that lysophagy prevents exogenous \u03b1Syn aggregates from escaping the endosomal-lysosomal system and transmitting aggregation to endogenous cytosolic \u03b1Syn via ruptured lysosomal vesicles. Our findings suggest that the progression and severity of synucleinopathies are associated with damage to lysosomal membranes and impaired lysophagy.",

This study examines the physiological and neurotoxic effects of these minuscule nanoplastic particles on the nematode Caenorhabditis elegans as well as on human cells. Here, we find that 25\u00a0nm polystyrene nanoplastic particles can inhibit animal growth and movement at very low concentrations, with varying effects on their surface groups. Furthermore, these nanoplastic particles not only accumulate in the digestive tract but also penetrate further into extraintestinal tissues. Such nanoplastics significantly compromise the integrity of the intestinal barrier, leading to \"leaky gut\" conditions and cause mitochondrial fragmentation in muscles, which possibly explains the observed movement impairments. A striking discovery was that these nanoplastics exacerbate symptoms similar to those of Parkinson's disease (PD), including dopaminergic neuronal degeneration, locomotor dysfunction, and accumulation of \u03b1-Synuclein aggregates. Importantly, our study demonstrates that the detrimental effects of nanoplastics on the aggregation of \u03b1-Synuclein extend to both C. elegans and human cell models of PD. In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems. ENVIRONMENTAL IMPLICATION: The escalating prevalence of nanoplastics in the environment due to widespread plastic usage raises potential health risks. Studies conducted on C. elegans indicate that even low concentrations of 25\u00a0nm polystyrene nanoplastics can impair growth and movement. These particles accumulate in the digestive system, compromising the intestinal barrier, causing \"leaky gut\", as well as inducing Parkinson's-like symptoms. Importantly, in both C. elegans and human cell models of Parkinson's disease, such nanoplastics penetrate tissues or cells and increase \u03b1-Synuclein aggregates. This underscores the urgent need to understand the interactions of nanoplastics with biological systems and highlights potential environmental and health consequences.",

Here, we demonstrate that the VCP inhibitors, DBeQ and ML240 elicit the activation of NLRP3 inflammasome in bone marrow-derived macrophages (BMDMs) when used as activation stimuli. Moreover, genetic inhibition of VCP or VCP chemical inhibition enhances lysosomal membrane damage and augments LLoME-associated NLRP3 inflammasome activation in BMDMs. Similarly, VCP inactivation also augments NLRP3 inflammasome activation mediated by aggregated alpha-synuclein fibrils and lysosomal damage.

GBA1 encodes the lysosomal enzyme beta-glucocerebrosidase (GCase), which orchestrates the degradation of glucosylceramide (GluCer) in the lysosome. Recent studies have shown that GluCer accelerates \u03b1-synuclein aggregation, exposing GCase deficiency as a major risk factor in PD pathology and as a promising target for treatment. This study investigates the interaction of GCase and three disease-associated variants (p.E326K, p.N370S, p.L444P) with their transporter, the lysosomal integral membrane protein 2 (LIMP-2). Overexpression of LIMP-2 in HEK 293T cells boosts lysosomal abundance of wt, E326K, and N370S GCase and increases/rescues enzymatic activity of the wt and E326K variant. Using a novel purification approach, co-purification of untagged wt, E326K, and N370S GCase in complex with His-tagged LIMP-2 from cell supernatant of HEK 293F cells is achieved, confirming functional binding and trafficking for these variants. Furthermore, a single helix in the LIMP-2 ectodomain is exploited to design a lysosome-targeted peptide that enhances lysosomal GCase activity in PD patient-derived and control fibroblasts. These findings reveal LIMP-2 as an allosteric activator of GCase, suggesting a possible therapeutic potential of targeting this interaction.",

Our results revealed that the use of TWW rendered MPs accumulation in earthworms' tissues and induce alteration on the intestinal mucus. An important cytotoxicity time-depending was observed being associated with an increase on genotoxicity.

We used LRRK2R1627P knock-in rats (human LRRK2-R1628P corresponds to rat LRRK2-R1627P) to investigate the R1627P mutation on function of dopaminergic neurons (DANs) and their susceptibility to the environmental toxin Lipopolysaccharide (LPS) during aging. LRRK2R1627P rats showed no significant loss of DANs, dopamine and its metabolites, or motor dysfunction; however, spontaneous exploration and olfactory discrimination reduced, and dendritic spines of DANs showed degeneration. We found decreased pThr73-Rab10 located on the trans-Golgi, disrupted Golgi structure and lipofuscin accumulation in aged LRRK2R1627P rat DANs, and the protein related to trans-Golgi complex and regulating lysosome function were significantly reduced. Although the neuroinflammation of brain was not obvious in the aging process, we confirmed a decrease in the ratio of CD4+/CD8+ and B cells, an increase in inflammatory factors (TLR4, NFKB, TNF-\u03b1) in the periphery. Furthermore, we demonstrated that the R1627P mutation caused the abnormal accumulation of \u03b1-Syn in the aged rat intestine. LPS exacerbated pathological \u03b1-Syn aggregation in the small intestine of LRRK2 transgenic rats and spread to the brain via the gut-brain axis. This led to microgliosis in the substantia nigra, creating a pro-inflammatory environment and inducing DANs degeneration. Gut-brain axis disruption may be a key determinant of progression to R1628P-PD in R1628P carriers. This insight has important clinical implications and highlights the importance of monitoring and addressing gut-brain axis integrity in individuals with LRRK2 mutations.",

However, the likelihood of developing PD with inherited LRRK2 pathogenic variants differs (a phenomenon known as \"reduced penetrance\"), with factors including age and geographic region, highlighting a potential role for lifestyle and environmental factors in disease onset. To investigate this, household dust samples from four different groups of individuals were analyzed using metabolomics/exposomics and metagenomics approaches: PD+/LRRK2+ (PD patients with pathogenic LRRK2 variants; n\u00a0=\u00a011), PD-/LRRK2+ (individuals with pathogenic LRRK2 variants but without PD diagnosis; n\u00a0=\u00a08), iPD (PD of unknown cause; n\u00a0=\u00a011), and a matched, healthy control group (n\u00a0=\u00a011). The dust was complemented with metabolomics and lipidomics of matched serum samples, where available. A total of 1,003 chemicals and 163 metagenomic operational taxonomic units (mOTUs) were identified in the dust samples, of which ninety chemicals and ten mOTUs were statistically significant (ANOVA p-value\u00a0<\u00a00.05). Reduced levels of 2-benzothiazolesulfonic acid (BThSO3) were found in the PD-/LRRK2+\u00a0group compared to the PD+/LRRK2+\u00a0. Among the significant chemicals tentatively identified in dust, two are hazardous chemical replacements: Bisphenol S (BPS), and perfluorobutane sulfonic acid (PFBuS). Furthermore, various lipids were found altered in serum including different lysophosphatidylethanolamines (LPEs), and lysophosphatidylcholines (LPCs), some with higher levels in the PD+/LRRK2+\u00a0group compared to the control group. A cellular study on isogenic neurons generated from a PD+/LRRK2+\u00a0patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis. This pilot study demonstrates how non-target metabolomics/exposomics analysis of indoor dust samples complemented with metagenomics can prioritize relevant chemicals that may be potential modifiers of LRRK2 penetrance.",

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP. SYNOPSIS: The cytotoxicity and its related mechanisms of nano-plastic is still unclear. This study found that nano-plastics may induce necroptosis in cells, and autophagy blockade and lysosomal dysfunction are prodromal manifestations.",

Pathological protein aggregates activate the microglial NLRP3 inflammasome resulting in proinflammatory signaling, secretion, and potentially pyroptotic cell death. We characterized mixed sex primary mouse microglia exposed to microbial stressors and alpha synuclein preformed fibrils (\u03b1syn PFFs) to identify cellular mechanisms related to Parkinson's disease. Microglia package and release the endosome fate regulator Coronin1A (Coro1A) in EVs in an Nlrp3-dependent manner in widely used experimental activation conditions. We were surprised to find that Coro1A packaging and release was not Nlrp3-dependent in \u03b1syn PFF exposure conditions. Coro1A-/- microglia exposed to \u03b1syn PFFs trafficked more \u03b1syn to the lysosomal compartment increasing lysosomal membrane permeabilization. This corresponds to a decrease in \u03b1syn released in EVs suggesting that Coro1A functions to shunt pathological proteins to a secretory pathway to attenuate lysosomal stress. \u03b1syn PFF-driven lysosomal stress resulting from Coro1a loss was associated with enhanced cytotoxicity. Intrinsic apoptosis signaling was unaffected, but we observed elevated cytosolic cathepsin B and the presence of a cathepsin-associated 55\u2005kD PARP cleavage product. Postmortem analysis of the PD mesencephalon supported a role for Coro1A in microglia, revealing elevated levels of Coro1A protein in human PD brains compared with those of healthy donors. Findings are relevant to the distribution of pathological \u03b1syn and indicate that Coro1a protects microglia from lysosomal overload, inflammasome activation, and pyroptotic demise.",

It easily crosses the blood-brain barrier. TSC has neuroprotective effects. Bisphenol A (BPA) is an endocrine-mimicking compound that induces Parkinson-like disease by impacting the dopaminergic system. In this research, the effects of TSCs on BPA-induced Parkinson-like symptoms via behavioral and molecular assays have been investigated. Male Wistar rats received BPA (75 mg/kg, gavage), TSC (10, 20, and 40 mg/kg), and levodopa (L-dopa) (10 mg/kg) via intraperitoneal injection (IP) for 28 days. Parkinsonian-like motor features were evaluated using bar test, rotarod, and open field experiments. Malondialdehyde (MDA) and glutathione (GSH) levels were also measured as the most important indicators of oxidative stress. Western blotting was performed for the molecular assays of alpha-synuclein (\u03b1-syn), Bcl-2, Bax, caspase-3, Beclin, and LC3 I/II proteins. Our analyses indicated that treatment with TSC at high dose reduces MDA levels and protects GSH reserves. TSC can also increase anti-apoptotic Bcl-2 and decrease pro-apoptotic Bax and caspase-3 proteins. While it does not affect autophagy markers, TSC decreased \u03b1-syn protein expression, reduced the catalepsy time, and improved the time spent staying on the rotating bar and the locomotor activity. Overall, TSC likely ameliorates BPA-mediated Parkinson' s-like symptoms by suppressing oxidative stress inhibition. This leads to reduced \u03b1-syn expression, which ultimately results in apoptosis inductions. Therefore, TSC can serve as a promising exploratory target for future research aimed at controlling Parkinson's disease.",

Nevertheless, their toxicity mechanisms in soil invertebrates remain unclear. This study investigated the impact of polystyrene NPs on Eisenia fetida (Savigny, 1826) immune cells, focusing on oxidative stress, immune responses, apoptosis, and necrosis. Results showed that 100 nm NPs were internalized into the cells, causing cytotoxicity. NPs were observed to inhibit cell viability by increasing reactive oxygen species, decreasing the levels of antioxidants (e.g., superoxide dismutase, catalase, and glutathione), and inducing lipid peroxidation and DNA oxidation. Additionally, assays on neutral red retention time, lysozyme activity, and Ca2\u207a levels demonstrated that NPs resulted in a loss of lysosomal membrane stability and a reduction in immune resistance. The depolarization of the mitochondrial membrane potential and the results of the apoptosis assays confirmed that the NPs induced the onset of early apoptosis. The difficulty of the NP in causing cell death by disrupting the plasma membrane was demonstrated by the results of the lactate dehydrogenase release assays in relation to cell necrosis. This research provides cellular-level insights into the ecological risks of NP exposure on soil fauna.",

Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of \u03b1 synuclein (\u03b1S) via the enteric nervous system, or the so-called gut-brain axis. Here we first examined the effect of enteric exposure to polystyrene nanoplastics on the peripheral and central pathogenesis of A53T, a representative \u03b1S mutant. Specifically, the polystyrene nanoplastics accelerated the amyloid aggregation of A53T \u03b1S, which subsequently elevated the in vitro production of glial activation biomarkers, cytokines, and reactive oxygen species and compromised mitochondrial and lysosomal membrane integrity, further shifting cellular metabolite profiles in association with PD pathophysiology. In vivo, coadministration of the polystyrene nanoplastics and A53T \u03b1S facilitated their synergistic gut-to-brain transmission in mice, leading to progressive impairment of physical and motor skills in resemblance to characteristic PD symptoms. This study provides insights into the response and vulnerability of Parkinson's gut-brain axis to polystyrene nanoplastics.",

The present study investigated the effects of carnosic acid (CA) on BPA-induced motor deficits and explored the role of parkin in the autophagic mechanism. First, C57BL/6\u00a0J male mice were orally administered with CA (5\u00a0mg/kg and 20\u00a0mg/kg) or RE (80\u00a0mg/kg rosemary extract) to test the motor function and anxiety-like behaviors in BPA (50\u00a0\u03bcg/kg) treatment. The results showed that CA and RE ameliorate BPA-induced motor impairments and anxiety-like behaviors. Moreover, CA and RE attenuated BPA-induced phosphorylation of tau and \u03b1-synuclein while restoring the expression levels of autophagy-related proteins, including parkin, PINK1, PI3K, Atg7, Beclin1, and LC3B-II. Then, SH-SY5Y cells were treated with 20\u00a0nM BPA and 1\u00a0\u03bcM CA or 0.5\u00a0\u03bcg/mL RE for 18\u00a0h. The results showed that treatment of CA and RE with BPA activated the parkin pathway and reduced the levels of Ser396p-tau and p-\u03b1-synuclein. Moreover, treatment of CA or RE with BPA restored the parkin signaling, resulting in the upregulation of autophagy-related proteins. However, wortmannin treatment attenuated this restorative effect of CA or RE. Additionally, transfection with parkin siRNA in cells reversed the ability of CA or RE to counteract BPA-induced reductions in autophagy-related proteins and increased the accumulation of misfolded proteins. Therefore, the results indicated that CA and RE improved motor impairments and reduced the accumulation of misfolding proteins induced by BPA, potentially through regulating autophagy by parkin.",

Here, we conducted a systematic review of the existing literature, which included 26 studies providing evidence from cellular and animal studies on the risks posed by MPs/NPs to the nervous system. In vitro studies reveal that MPs/NPs can disrupt the integrity of the blood-brain barrier, penetrate neurons and glial cells, impair cell membrane integrity, and induce cytotoxic effects. These plastic particles trigger oxidative stress, inflammation, and mitochondrial dysfunction, alter signaling pathways, and disrupt neuronal communication, potentially leading to neurological dysfunction, cognitive deficits, and neurodegenerative disorders like Alzheimer's and Parkinson's diseases. Animal models corroborate these findings, demonstrating behavioural changes, memory impairment and neurotransmitter imbalances following exposure to MPs/NPs. Although the evidence in humans is limited, the growing body of hazard data underlines the potential risks associated with chronic exposure and accumulation of MPs/NPs in the nervous system. This highlights the urgent need for further research to elucidate the mechanisms of neurotoxicity, as well as stringent regulatory measures to restrain plastic pollution and safeguard neurological health.",

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD.",

However, most existing research has focused on single exposure, which is not consistent with the actual exposure circumstance. In this study, single and co-exposure animal model were established. C57/BL6J mice were exposed to corn oil, 20\u00a0mg/kg PS-MPs, 200\u00a0mg/kg DEHP and PS-MPs\u00a0+\u00a0DEHP for 28 days. The HE staining showed more serious seminiferous epithelium disorganization in co-exposed mice, indicating that PS-MPs and DEHP co-exposure could aggravate testicular injury. Compared with control group, integrative analysis of transcriptomics and proteomics revealed that PPAR\u03b3 pathway played a crucial role in PS-MPs and DEHP co-exposure induced testis injury. In vitro, spermatocytes (GC-2) and leydig cells (TM3) were exposed to 50\u00a0\u03bcM MEHP, 10\u00a0mg/L PS-MPs and PS-MPs\u00a0+\u00a0MEHP for 48\u00a0h. Though PS-MPs and MEHP single exposure also triggered oxidative stress and PPAR pathway, the protein levels showed more remarkable difference in co-exposure group. Furthermore, co-exposure to PS-MPs and MEHP induced lysosomal membrane permeabilization (LMP), which significantly impaired lysosomal-mediated lipid degradation, thereby exacerbating lipid metabolism dysfunction in testicular cells. Treatment with N-Acetylcysteine (NAC) and knockdown of fatty acid-binding protein (FABP4) restored lipophagy flux and reduced lipid droplets deposition. Overall, co-exposure of PS-MPs and DEHP has synergistic toxic effect, inducing oxidative stress, PPAR\u03b3 activation and lipophagy blockage, finally resulting in unbalanced lipid metabolism and testicular damage.",

Although fragmented and fibrous MPs are the most abundant shapes in marine environment, studies on shape- and size-dependent MP toxicity in marine benthic bivalves remain limited. In this study, we aimed to evaluate the chronic effects of different shapes and sizes of polyethylene terephthalate (PET) MPs on Manila clam Ruditapes philippinarum, and investigate their physiological and cellular responses. The mortality of R. philippinarum showed no changes at all concentrations of fragmented and fibrous MPs. The respiration rate of R. philippinarum induced by large fragmented MPs was recovered to the control level at 6\u2009h, however, fibrous MPs significantly decreased compared to the control. In particular, fibrous MPs significantly increased and decreased filtration rate and lysosomal membrane stability, respectively, whereas the fragmented MPs showed no significant differences. These results enhance our understanding of the potential toxicological risks posed by MPs of various shapes and sizes to benthic organisms in marine environment.",

These pollutants are increasingly implicated in the pathogenesis of neurodegenerative diseases. Due to their nanoscale size and surface reactivity, MNPs can cross the blood-brain barrier, accumulating in neural tissues. Once internalized, they disrupt neuronal homeostasis by inducing oxidative stress, mitochondrial dysfunction, and chronic neuroinflammation, key processes in neurodegenerative progression. Mitochondria, central to neuronal energy and redox regulation, are particularly vulnerable, leading to impaired ATP production, elevated ROS, and pro-apoptotic signaling. Recent studies reveal that MNPs also induce epigenetic changes, including aberrant DNA methylation, histone modifications, and dysregulation of non-coding RNAs. These alterations can result in synaptic instability, persistent transcriptional reprogramming, and heightened susceptibility to diseases like Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis. The mitochondrial epigenome is a vital target of MNP-induced disruption, offering potential biomarkers like methylated mtDNA and microRNAs for early diagnosis and prognosis. Understanding the molecular mechanisms behind these epigenetic alterations is essential for developing practical diagnostic tools and therapies. This review provides a comprehensive overview of MNP-induced neurodegeneration, focusing on mitochondrial and epigenetic disruptions. Moreover, it explores emerging biosensing technologies for detecting MNP-induced epigenetic alterations, highlighting the urgent need for further investigation to fully understand the neurotoxic potential of MNPs and develop preventive and therapeutic strategies for mitigating their effects on brain health.",

This has led to the inevitable intake by humans, through different routes, of small plastic particles, the micro and nano-plastics (MNPs) with sizes ranging from nanometers (<1000\u202fnm) to micrometers (from 5\u202fmm to 1\u202f\u00b5m). MNPs can cause harmful effects in human tissues and organs, contributing to the early onset of aging and various age-related diseases. A growing body of evidence supports this toxic role of MNPs. In this regard, it has been shown that their different chemical and physical properties, including different chemical composition with different additives, different size, shape, solubility and ability to interact with metals and microbial agents, as well as the duration of multiple exposures, modulate their toxic action. In the brain, as documented mainly by studies conducted on brain tissues of deceased individuals, nanosized nanoparticles (NPs) of mostly 50\u202fnm or smaller, made of polyethylene, bioaccumulate, causing damage. The mechanisms involved do not seem to be fully understood. However, studies on animal models and human cell cultures using plastic particles made of synthetic polystyrene, of slightly larger dimensions, partially clarify this aspect. They demonstrated that these particles have the unique ability to cross the blood-brain barrier and evoke neurotoxicity, through the activation of pathways that determine oxidative stress, inflammation, apoptosis, altered synthesis of neurotransmitters, endocrine molecules and key enzymes related to nerve conduction, and able to influence the gut-brain axis. Despite the paucity of studies conducted directly in humans, this review collects a growing body of evidence demonstrating that exposure to MNPs, and essentially NPs, can damage neurons. This could lead to alterations in learning, memory and behaviour, and could evoke additional potential negative impacts, contributing to amplifying neuroinflammation and the onset of neurodegenerative disorders, such as Alzheimer's and Parkinson's diseases. Preventive approaches and measures to limit their use and human exposure, as well as potential therapeutic strategies, are also suggested.",

This dual threat complicates their ecological impact, especially concerning compartments like the coelomic fluid, crucial for marine invertebrate physiology. In this study, we investigated the toxicological effects of environmentally relevant concentrations of MPs (10 and 50\u202fmg/kg sediment), both alone and in combination with benzo[a]pyrene (B[a]P, 1\u202f\u00b5g/kg sediment), a carcinogenic polycyclic aromatic hydrocarbon known for its genotoxic and pro-apoptotic properties. The benthic polychaete Hediste diversicolor was exposed to these treatments for 7 days through spiked sediments, simulating realistic environmental conditions. The MPs used were particles smaller than 30\u202f\u00b5m, composed of a mixture of polymers, including PE, PET, PP, LDPE, HDPE, and PEVA, with varied morphologies such as fragments, fibers, and films. Analyses revealed that both MPs and B[a]P were internalized by coelomocytes, with MPs enhancing B[a]P bioaccumulation. Combined exposures led to marked cytotoxic and genotoxic effects, evidenced by decreased lysosomal membrane stability (LMS), elevated micronuclei frequency (FMN), and increased DNA fragmentation, as assessed by terminal dUTP nick-end labeling (TUNEL) assay. Co-exposure also altered apoptotic and DNA repair pathways, as demonstrated by upregulation of P53, Bax, and Casp-3, alongside downregulation of the anti-apoptotic marker Bcl-2. These findings suggest that co-exposure intensifies cellular damage and apoptotic signaling. Overall, this study underscores the risks of MPs in marine ecosystems, particularly their role in accumulating and transferring harmful substances affecting biota health.",

However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution.",

A key event in this process is the rupture of endolysosomal vesicles following the intercellular transfer of MAPT/Tau aggregates, releasing the transferred MAPT/Tau species into the cytosol where they can promote the aggregation of endogenous MAPT/Tau. However, understanding of the cellular pathways involved in this process remains limited. In this study, we investigated cellular pathways that prevent endolysosomal vesicle rupture. We established a new C. elegans model of MAPT/Tau spreading by introducing an mCherry-labeled, disease-associated aggregation-prone fragment of human MAPT/Tau (F3\u0394K281::mCh) into the six touch receptor neurons. F3\u0394K281::mCh transgenic animals exhibited significant neurotoxicity and mechanosensory deficits due to the accumulation of this MAPT/Tau fragment. In addition, its intercellular transmission compromised the endolysosomal system in receiving hypodermal cells. Using this model, we conducted an unbiased genome-wide RNAi screen and identified 59 genes critical for maintaining endolysosomal integrity. GO-term analysis revealed an enrichment of genes related to the ESCRT complex, the ubiquitin-proteasome system, mRNA splicing, and fatty acid metabolism. Silencing of selected conserved genes exacerbated seeded MAPT/Tau aggregation in a human induced pluripotent stem cell (hiPSC)-derived cortical neuron model and triggered endolysosomal rupture in HEK293T cells, confirming the crucial role of endolysosomal damage in seeded MAPT/Tau aggregation. Overall, this study discovered novel cellular pathways that safeguard endolysosomal integrity. These findings may guide the development of therapeutics that improve endolysosomal integrity to halt the progression of MAPT/Tau pathology.Abbreviations: AD: Alzheimer disease; ALM: anterior lateral microtubule cell; AVM: anterior ventral microtubule cell; BWM: body wall muscle; C. elegans: Caenorhabditis elegans; DA: dopaminergic; hiPSC: human induced pluripotent stem cell; LGALS3: galectin 3; MAPT/Tau: microtubule associated protein tau; mCh: monomeric Cherry; PD: Parkinson disease; PLM: posterior lateral microtubule cell; PVM: posterior ventral microtubule cell; sfGFP: superfolder green flourescent protein; SNCA: synuclein alpha; nt-cntrl: non-targeting siRNA; rPHFs: recombinant paired helical filaments.",

Upon uptake, such particles disturb neuronal homeostasis by multiple converging pathways, including oxidative stress, mitochondrial dysfunction, pathological protein aggregation, and chronic neuroinflammation, all closely involved with the molecular signatures of neurodegenerative disorders (Alzheimer's, Parkinson's, Amyotrophic Lateral Sclerosis-ALS). In addition to their neurotoxicity, recent findings suggest that NMPs could disturb synaptic communication and neuroplasticity, thereby compromising the brain's capacity to recover from an injury, a trauma, or neurodegeneration, thus impacting the progression of the disease, our ability to treat it and eventually the efficacy of rehabilitation approaches. Despite these findings, our understanding remains hampered by analytical issues, the scarcity of standard detection methods, and a total lack of longitudinal studies in humans. This review combines multidisciplinary evidence on brain-plastic interactions and calls for accelerated advances in our ability to monitor bioaccumulation in humans, and to integrate neurotoxicology paradigms in the assessment of this underappreciated but growing threat to brain health.",

Disruptions in this axis, driven by gut dysbiosis, have been implicated in the pathogenesis of a wide range of neurodegenerative and neuropsychiatric disorders. This review synthesizes current evidence linking microbiota alterations to Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and stroke-including post-stroke cognitive impairment (PSCI), as well as major depressive disorder (MDD), bipolar disorder (BD), anxiety disorders, post-traumatic stress disorder (PTSD), and chronic fatigue syndrome (CFS). Common findings include reduced microbial diversity, depletion of short-chain fatty acid (SCFA)-producing genera, and enrichment of pro-inflammatory taxa. These changes contribute to neuroinflammation, blood-brain barrier (BBB) dysfunction, microglial activation, and neurotransmitter imbalances. The review further explores the neurotoxic effects of external factors such as radiation and xenobiotics on the MGBA. Despite disorder-specific variations, shared microbial and immunological mechanisms emerge across the spectrum of conditions. Importantly, we present current and emerging strategies aimed at restoring gut-brain communication, including dietary interventions such as fiber-rich and Mediterranean diets, SCFA supplementation, probiotics, and fecal microbiota transplantation (FMT). These approaches show promise in alleviating cognitive and emotional symptoms, modulating immune responses, and potentially slowing disease progression. By integrating mechanistic insights with therapeutic perspectives, this review underscores the gut microbiota as a modifiable factor in neuropsychiatric and neurodegenerative disease. Targeting the MGBA offers a novel, translational approach to intervention that may ultimately contribute to healthier brain aging and improved outcomes across the lifespan.",

This study explored how polystyrene (PS) nanoplastics contributed to PD progression by examining their metabolic impact in an A53T \u03b1-synuclein (\u03b1S) mouse model. Mice given PS nanoplastics orally (2\u2009mg/kg every other day for three months) displayed compromised gut barrier integrity, including a 30% drop in goblet cells and increased epithelial apoptosis in the ileum. Microbial diversity in the ileum rose sharply, with an overgrowth of Desulfovibrio spp. linked to neuroinflammation and \u03b1S aggregation. KEGG analysis confirmed apoptosis and lipopolysaccharide biosynthesis pathways influenced by nanoplastics, while metabolomics identified over 200 altered fecal metabolites, including those associated with cytochrome P450 activity and disruptions to cancer-related pathways. Additionally, histopathology revealed liver inflammation, underscoring the systemic effects of nanoplastic exposure. Overall, our findings suggest that environmental nanoplastics may aggravate PD physiopathology through gut-liver axis disruption and metabolic dysregulation.",

Reports that MNPs can breach the blood-brain barrier and accumulate inside the brain have raised concerns over their possible involvement in the development of neurogenerative diseases. The aggregation of the abundant neuronal protein \u03b1-synuclein (\u03b1-syn) is pertinent to almost 50 neurological diseases including Parkinson's disease (PD). The role of nanoplastics in the formation of toxic aggregates is unclear and has been shown to depend strongly on the type of plastics. Here we report the molecular structure and orientation of human \u03b1-syn adsorbed on polystyrene NPs using interface-specific sum frequency scattering (SFS) and structure-sensitive two-dimensional infrared (2D IR) spectroscopy. The SFS experimental data were compared with the calculated spectra of several thousands of \u03b1-syn conformations generated from molecular dynamics simulations. The SFS results reveal that \u03b1-syn folds on polystyrene nanoplastics, adopting a partly helical structure with the N-terminus and nonamyloid component regions directly bound on the polystyrene nanosurface, while the C terminus protrudes away from the polystyrene interface. 2D IR results suggest that the entire \u03b1-syn corona comprises of partly aggregated \u03b1-syn structures, built of an ordered core enclosed with flexible dynamic regions. The data shed light on the mechanism by which \u03b1-syn folds and forms aggregates at the plastic particle surfaces, a link that has been missing in understanding the role of nanoplastic in the pathogenesis of PD and related neurodegenerative diseases.",

In this study, we collected whole blood samples from 21 PD patients and 12 age- and sex-matched healthy controls under strict anticontamination protocols. A lifestyle questionnaire was administered to assess MP exposure-related habits, revealing that PD patients reported more frequent use of disposable plastic products and bottled water consumption, suggesting greater environmental exposure. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR) and scanning electron microscopy (SEM) were used to quantify and characterize the MPs. Five polymer types-polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and nylon-66 (PA66)-were detected in the sample. The total MP burden was significantly greater in PD patients than in controls (21.36\u202f\u00b1\u202f8.42 vs. 13.56\u202f\u00b1\u202f5.92\u202f\u03bcg/g; p\u202f<\u202f0.01), with the greatest increases observed for PVC (1.49-fold), PP (2.74-fold) and PA66 (6.62-fold), whereas the PE and PS levels were not significantly different. LDIR and SEM analyses revealed diverse particle morphologies, with most polymers appearing as granular particles. In vitro assays further revealed that PVC and PP microplastics induced dopaminergic neuron apoptosis and increased the level of phosphorylated \u03b1-synuclein (p-\u03b1-syn), providing support for their potential neurotoxicity. Together, these findings indicate elevated blood MP levels in PD patients and offer preliminary evidence linking polymer exposure with PD-related neuronal vulnerability.",

Shared pathophysiological pathways for Alzheimer's and Parkinson's disease.\nAbstract: The widespread presence of microplastics (MPs) in the environment has raised significant concerns about their potential impact on human health. As of 2023, the Ocean Conservancy estimates that adults may ingest up to 121,000 MPs annually. While the majority of these particles are cleared from the body, a small fraction can persist, as MPs are non-biodegradable and resist breakdown, posing long-term health risks that remain poorly understood. This review explores the emerging link between MP exposure and the development of neurodegenerative diseases, particularly Alzheimer's disease (AD) and Parkinson's disease [1]. MPs appear capable of triggering neurotoxic pathways, including activation of resident immune cells in the brain, oxidative stress, blood-brain barrier (BBB) disruption, mitochondrial dysfunction, and neuronal damage, which may contribute to neuroinflammation and disease progression. Specifically, six MP-related mechanistic pathways associated with AD were identified: BBB disruption, chronic inflammation, oxidative stress and ROS generation, mitochondrial dysfunction, impaired autophagy and proteostasis, and epigenetic alterations. Similarly, six pathways were implicated in PD: BBB disruption, oxidative stress in dopaminergic neurons, mitochondrial dysfunction, microglial-driven neuroinflammation, \u03b1-synuclein aggregation, and gut-brain axis [2] disruption. Ultimately, our findings underscore the urgent need for further research into the neurological consequences of chronic MP exposure in humans and highlight the importance of strengthening global policies to curb plastic pollution and mitigate its long-term health risks.",

Wild-type and transgenic strains were exposed to PS-NPs at concentrations of 0.1-100\u00a0\u03bcg/L to assess behavioral toxicity, neuronal damage, and molecular mechanisms. Locomotor deficits (reduction in body bends and head thrashes) and disrupted PD-associated behaviors (impairment of food-induced basal slowing response; increased swimming paralysis rate) were observed at all concentrations, while developmental parameters remained unaffected. Although some behavioral endpoints didn't exhibit a strictly monotonic dose-response, Jonckheere-Terpstra trend analyses confirmed significant overall trends for multiple key parameters, underscoring the pervasive impact of PS-NP exposure. Selective degeneration of dopaminergic neurons and exacerbated \u03b1-synuclein aggregation confirmed neuropathological specificity. Transcriptomic analysis linked these phenotypes to oxidative stress, showing elevated reactive oxygen species (ROS) and upregulation of antioxidant enzymes (SOD-3, GST-4), alongside paradoxical suppression of the redox regulator skn-1. Genetic validation using trx-1 mutants prevented PS-NP-induced paralysis, whereas trx-4 deficiencies exacerbated toxicity, highlighting their distinct roles in redox defense. Co-treatment with N-acetylcysteine (NAC) attenuated PS-NP-induced paralysis, lowering the rate from 51.33\u00a0% to 29.47\u00a0%, though rescue failure in trx-4 mutants indicated mechanistic complexity and the indispensable role of endogenous defense systems. Critically, neurotoxicity occurred even at 0.1\u00a0\u03bcg/L PS-NPs, a level relevant to environmental contamination. These findings establish PS-NPs as potent inducers of PD-like neurodegeneration via complex oxidative stress cascades, validated by genetic and antioxidant interventions at environmentally realistic exposure levels, and highlight the urgency of monitoring nanoplastic pollution and developing antioxidant-based interventions.",

However, evidence from community-based biomarker studies in highly polluted Indian regions remains sparse. To investigate the neuroinflammatory and neurodegenerative effects of chronic exposure to ambient air pollutants in long-term residents of a critically polluted area compared to a control region. This cross-sectional study included 203 adults (aged 40-60) residentially exposed to critical levels of air pollutants for \u2265\u200910 years and 202 geo-demographically matched controls residing at locations with very low / minimal air pollution. Air pollutant levels across all seasons were measured according standard protocols. Blood samples were analyzed for neurological biomarkers (viz. A\u03b21-42, Total Tau, \u03b1-Synuclein, brain-derived neurotrophic factor (BDNF), and glial fibrillary acidic protein (GFAP) using ELISA. Additionally, demographic, clinical (blood pressure, random blood sugar, lipid profile) and occupational data were collected. Appropriate, descriptive, comparative and regression statistics were applied after checking for the normality. Annual PM2.5 and ozone concentrations were significantly higher at the exposed site (PM2.5: 69.76\u2009\u00b1\u200915.99\u00a0\u00b5g/m\u00b3; ozone: 33.76\u2009\u00b1\u200911.58\u00a0\u00b5g/m\u00b3) compared to controls (p\u2009<\u20090.001). Exposed participants showed significantly elevated GFAP (p\u2009<\u20090.001) and A\u03b21-42 (p\u2009=\u20090.044), and significantly reduced levels of total tau, \u03b1-synuclein, and BDNF (p\u2009<\u20090.001), suggesting glial activation and impaired neuroprotection. Regression analyses confirmed exposure as a key predictor of biomarker variance, independent of age, BMI, blood pressure, and lipid levels. Chronic exposure to critical levels of ambient air pollutant is associated with subclinical alterations in neuroinflammatory and neurodegenerative plasma biomarkers. These findings underscore the potential for air pollution to contribute to neurological dysfunction and support the need for public health interventions and longitudinal studies. Further, plasma-based biomarkers replicated results previously reported using cerebrospinal fluid (CSF) and post-mortem tissue samples, thereby enabled minimally invasive detection of neurobiological alterations at the community level, supporting their potential utility in population-level environmental health research.",

However, their influence on the toxicokinetics and biological effects of NPs in marine mussels remains largely unknown. Here, the green mussels (Perna viridis) were exposed to NPs and HAs at their environmentally relevant concentrations for 21 d, followed by a 7-d depuration phase. The effects on toxicokinetics, immunological responses, and microbiota of digestive gland were evaluated. The results showed that HAs increased the uptake rate constant in digestive gland by 5.5-fold and tissue accumulation of NPs by 2.5-fold compared to NPs alone, resulting in higher NPs burdens after depuration. Meanwhile, HAs exacerbated NPs-induced immunotoxicity, including increased hemocyte mortality and ROS production, and decreased phagocytosis and lysosomal membrane stability. Moreover, HAs led to more pronounced dysbiosis of microbiota in digestive gland than NPs alone, reducing fungal diversity by 56\u202f% and enriching opportunistic fungal pathogens such as Fusarium, while bacterial communities showed minor shifts. This study has provided critical evidence that HAs act as a \"Trojan horse,\" exacerbating NPs risks. This study highlights the necessity of adding the naturally occurring HAs into the ecological risk assessment framework of NPs, especially for benthic filter-feeding organisms.",

This review synthesizes recent research findings to provide a comprehensive overview of the effects of MPs/NPs on the brain. Evidence demonstrates that MPs/NPs can cross critical biological barriers, including the blood-brain barrier and the placenta, gaining access to the central nervous system (CNS) and the developing fetal brain, influenced by particle size, charge, and the biomolecular corona. Once present, MPs/NPs trigger multiple detrimental pathways, including oxidative stress, persistent neuroinflammation involving microglia and astrocytes, mitochondrial dysfunction leading to energy deficits, disruption of crucial neurotransmitter systems, and direct neuronal damage. Critically, NPs have been shown to promote the aggregation of proteins implicated in neurodegeneration, such as alpha-synuclein. These mechanistic disturbances translate into observable adverse outcomes in experimental models, ranging from cognitive impairments in learning and memory to behavioral abnormalities and pathologies resembling human neurodegenerative and neurodevelopmental disorders. Toxicity is modulated by particle characteristics, co-exposures, and host factors like age and sex, with indirect effects via the gut-brain axis also playing a significant role. While current evidence, primarily from animal models often using high doses, strongly indicates a neurotoxic potential, significant research gaps remain concerning human risk assessment under chronic, low-level environmental exposure conditions and the effects of environmentally aged, mixed-plastic particles. Future research should prioritize human studies, environmentally realistic exposure scenarios, and differentiating direct versus indirect neurotoxic mechanisms to accurately evaluate the threat MPs/NPs pose to human brain health.",

Accumulating evidence suggests that there are phenotypic, neuropathologic, and biological similarities between sporadic PD (sPD) and familial forms in which LRRK2 variants are inherited in an autosomal-dominant pattern with variable penetrance (LRRK2-PD). Further, genome-wide association studies have found specific non-coding variants that are risk factors for sPD. In this review, we describe the current state of knowledge as it relates to LRRK2's role in sPD, with a focus on comparing the physiology and pathology of sPD with LRRK2-PD. As in LRRK2-PD, LRRK2 activity may also be increased in sPD, possibly through interactions between genetics and the environment. Increased activity of LRRK2 and associated endolysosomal dysfunction have been observed in sPD patients, including evidence from postmortem brains of patients with sPD and animal models showing increased LRRK2 activity. Additionally, beneficial effects of LRRK2 inhibitors, such as improved lysosomal function, reduced \u03b1-synuclein accumulation, and amelioration of neurodegeneration, have been demonstrated in animal models of sPD. Therefore, inhibition of LRRK2 kinase activity may be a promising approach to disease modification for sPD and LRRK2-PD. Ongoing and future clinical studies examining LRRK2 kinase inhibitors will aim to elucidate their clinical efficacy in PD and to assess their potential effects on lysosomal function. \u00a9 2025 The Author(s).

Current literature suggests that microplastics may adversely affect the nervous system, with emerging evidence linking them to neurobehavioral disorders. However, many questions remain regarding the pathways of their environmental exposure, the specific effects on neurobehavior, and the underlying mechanisms of their impact. This review aims to explore the routes through which humans are exposed to microplastics, monitor behavioral changes associated with microplastic exposure, and examine how these particles infiltrate the body and traverse the blood-brain barrier. Several perspectives will be considered in assessing the potential mechanisms by which microplastics may influence neurobehavioral disorders, including oxidative stress, neurotransmitter regulation, and neuroplasticity. The article concludes by summarizing the effects of microplastics on neurobehavioral disorders, such as neurodegeneration and mood disorders, while analyzing the latest research findings.

This study investigated the impact of polystyrene microplastics (PS) on Nile tilapia (Oreochromis niloticus) macrophages and explored metabolic interventions to reverse PS-induced damage. PS exposure increased tilapia susceptibility to Streptococcus agalactiae infection, reducing fish survival. PS accumulated in head kidney macrophages, impairing phagocytosis, altering cytokine expression, elevating oxidative stress and malondialdehyde levels, and suppressing T-cell proliferation. Transcriptomics revealed PS dysregulated lysosomal pathways, reducing lysosomal membrane permeability and bacterial killing capacity. Metabolomic screening identified arachidonic acid (AA) as the most significantly suppressed metabolite in PS-exposed macrophages. Exogenous AA administration restored macrophage function including phagocytosis, cytokine expression, oxidative stress, enhanced lysosomal integrity, improved bactericidal activity, and increased survival during S. agalactiae challenge in PS-exposed fish.

Up to 20-fold increased risk of melanoma was reported in PD patients, while a personal/family history of melanoma was linked to a 1.85-fold PD risk. Neurons and melanocytes, which both derive from the neuroectodermal crest, share biological pathways that may be dysregulated in both diseases. In particular, accumulation of the alpha-synuclein (\u03b1-syn, SNCA) protein, a pathological hallmark of PD, is also observed in melanoma. Indeed, dysregulated \u03b1-syn proteostasis is known to disrupt several biological pathways which can co-incidentally, albeit paradoxically contribute to both neurodegeneration and hyper-proliferative cell growth. These include abnormalities in dopamine (DA), melanin, and iron metabolism, oxidative stress, DNA damage/repair response, inflammation, as well as alterations in mitochondrial function, and cell-clearing machinery. Although \u03b1-syn depletion was shown to attenuate melanoma cell proliferation and neurodegeneration, it remains unclear whether \u03b1-syn accumulation is a mere culprit of disease, if it represents a common outcome from shared upstream mechanisms, or, finally, a compensatory response to cellular stress. In an effort to elucidate how \u03b1-syn bridges melanomagenesis and the neurodegenerative events of PD, this review discusses specific cellular and molecular pathways related to \u03b1-syn proteostasis, including environmental factors implicated in melanocytic transformation, such as UV radiation. Addressing open questions and establishing novel experimental models remain essential for developing effective therapeutic approaches to target melanoma and PD without overlooking their comorbidity.",

Mutations in the glucocerebrosidase 1 (GBA1) gene have been identified as a significant genetic risk factor for both PD and DLB. GBA1 encodes for the lysosomal enzyme glucocerebrosidase, which is responsible for the breakdown of glucosylceramide (GC). Deficiencies in glucocerebrosidase activity lead to the accumulation of glucosylceramide within lysosomes, contributing to lysosomal dysfunction and impaired protein degradation. The aim of this narrative review is to update the underlying mechanisms by which GBA1 mutations contribute to the pathogenesis of PD and DLB. Methods: A comprehensive literature search was conducted across four major electronic databases (PubMed, Web of Science (Core Collection), Scopus, and Embase) from inception to 8 November 2025. The initial search identified approximately 1650 articles in total, with the number of hits from each database being as follows: PubMed (~450), Web of Science (~380), Scopus (~520), and Embase (~300). Results: The mechanism by which mutations in the GBA1 gene contribute to PD involves both loss-of- function and gain-of-function pathways, which are not mutually exclusive. Typically, GBA1 mutations lead to a loss of function by reducing the activity of the GCase enzyme, impairing the autophagy- lysosomal pathway and leading to \u03b1-synuclein accumulation. However, some mutant forms (GBA1L444P) of the GCase enzyme can also acquire a toxic gain of function, contributing to \u03b1-synuclein aggregation through mechanisms like endoplasmic reticulum stress and misfolding. While Venglustat effectively reduced GC levels, a key marker associated with GBA1-PD, the lack of clinical improvement led to the discontinuation of its development for this indication. Conclusions: GBA1-mediated lysosomal and lipid dysregulation represents a key pathogenic axis in PD and DLB. Understanding these mechanisms provides crucial insight into disease progression and highlights emerging therapeutic strategies-such as pharmacological chaperones, substrate reduction therapies, and gene-targeted approaches-aimed at restoring GCase function and lysosomal homeostasis to slow or prevent neurodegeneration.",

This study presents a comparative neurotoxicity model using adult zebrafish (Danio rerio) exposed to a 21-day static immersion protocol with environmentally relevant doses (2 and 4\u202fmg/L). Neurobehavioral changes were assessed using the novel tank diving test (NTDT) and a color-based T-maze test, combined with detailed histopathological scoring. BPA induced markedly stronger neurobehavioral and neuropathological effects than AlCl\u2083. BPA exposure caused dose-dependent reductions in swim velocity and distance travelled, heightened anxiety-like behavior, and cognitive inflexibility with reduced exploratory transitions and spatial learning. Histology revealed extensive vacuolation, neuronal pyknosis, and perineural congestion in the telencephalic and diencephalic regions, confirming widespread neurodegeneration. In contrast, AlCl\u2083 produced moderate impairments, with neuropathology primarily confined to the cerebellum and thalamus. These differential effects suggest distinct mechanisms: BPA may disrupt synaptic plasticity and hypothalamic-pituitary-interrenal (HPI) axis signaling, whereas AlCl\u2083 likely involves mitochondrial dysfunction and tauopathy. By integrating behavioral phenotyping with region-specific neuropathology, this model highlights the translational relevance of adult zebrafish for regulatory toxicology and human health risk assessment of aquatic neurotoxicants.",

This review integrates evidence from 129 research articles (2002-2025) to elucidate the mechanistic, biomarker-based, and public health dimensions of PM-induced neurotoxicity. Mechanistic pathways include oxidative stress, neuroinflammation, mitochondrial dysfunction, and blood-brain barrier disruption, with documented structural and functional damage in brain regions such as the hippocampus and prefrontal cortex. PM\u2082.\u2085 serves as a carrier of neurotoxic metals (e.g., lead, cadmium, vanadium) and understudied organic toxicants (e.g., PAHs, pesticides), amplifying its pathogenic potential. Exposure occurs through the olfactory route, systemic circulation, and gut-brain axis, highlighting multiple entry points into the central nervous system. Biomarkers such as A\u03b2\u2084\u2082, phosphorylated tau (p-tau), and \u03b1-synuclein are elevated in experimental models, but require greater validation in human PM-exposed populations. Children and older adults represent the most vulnerable groups due to developmental sensitivity and cumulative neuroinflammatory burden, yet remain underrepresented in cohort studies. Geographic disparities further limit generalizability, with low- and middle-income countries underrepresented despite experiencing the highest PM burdens.

Bisphenol-A (BPA) is one of the most potent endocrine disruptors used to synthesize poly-carbonate plastic for food and drink packages, as epoxy-resins in metal cans, sports, toys, and medical equipment and consumer electronics; whereas, the other is Phthalate [-diethyl phthalate (DEP)] that is found in cosmetics and personal care products. Euplotes crassus, an interstitial marine ciliate protozoan is a promising bioindicator for evaluating the toxicity of various aquatic environmental communities like sediments, fresh waters and waste waters. Euplotes crassus were used in our study to analyze the effect of BPA and DEP, identifying them as one of the major environmental pollutants in aquatic ecosystems. Our results demonstrate that widespread water contamination with BPA as well as phthalate causes potent cellular damage to this protozoan sentinel. Lethal and sublethal exposures of both these EDCs were found to cause extensive cellular damage affecting cell survival, replication rate, lysosomal membrane stability and endocytosis rate of Euplotes crassus at different doses and time intervals. Although cell death in Euplotes crassus was not that evident when treated with phthalate as opposed to BPA treatment and the protozoans survived at a higher levels of the dose of Phthalate; there was severe cellular and nuclear damage demonstrating that this EDC had a capacity of being more persistent and has a more deleterious effect in terms of biomagnification, indicating long-term harm, not only to the health of aquatic organisms but also to those at higher trophic levels that consume them as food.",

Surface-charged nPS variants (cationic, anionic, and neutral) show distinct biodistribution patterns, yet the mechanisms underlying their systemic damage remain incompletely understood. This study aimed to investigate the systemic injury mechanisms of nPS with different surface charges. Mice were exposed to fluorescently labeled cationic (amino-modified), anionic (carboxyl-modified), and neutral nPS via drinking water (25\u00a0mg/mL) for 3\u00a0weeks. Tissue distribution was analyzed using fluorescence microscopy; pathological changes were assessed via hematoxylin-eosin (HE) staining; metabolic perturbations were detected by metabolomic profiling. Mechanistic investigations were performed using metabolomics, flow cytometry, and molecular assays in AML12 hepatocytes and vascular endothelial cells. Fluorescence microscopy showed neutral nPS accumulated in the vascular endothelium of the stomach, intestine, and lung via passive diffusion, while cationic/anionic nPS penetrated hepatic sinusoids through charge-mediated interactions. HE staining revealed severe liver injury, with no significant abnormalities in other tissues. Metabolomic profiling indicated disrupted hepatic amino acid and lipid metabolism, depleted antioxidants (e.g., vitamin E and glutathione), and induced oxidative stress (evidenced by elevated hydroxy fatty acids). In hepatocytes, nPS-induced endoplasmic reticulum (ER) stress triggered excessive reactive oxygen species (ROS) production, inhibiting SLC7A11-mediated cystine uptake and glutathione synthesis, leading to disulfide stress (\u03b2-actin disulfide mispairing) and ferroptosis (GPX4 inactivation and iron accumulation). In contrast, neutral nPS induced endothelial cell senescence via phagolysosome dysfunction, causing lysosomal membrane permeabilization and \u03b2-galactosidase release. This study identifies a \"charge-specific injury\" paradigm: charged nPS induce hepatocyte ferroptosis via an ER stress-disulfide stress cascade, while neutral nPS trigger endothelial senescence through phagocytic dysfunction. These findings provide critical insights for the biosafety assessment of nanoplastics and identify potential targets for preventing plastic pollution-related liver diseases.",

These chemicals are widely found in various consumer products and industrial processes, and can lead to serious disorders of the endocrine system by disrupting hormone synthesis, expression, and function. The aim of this review was to examine epidemiological and experimental findings by investigating the link between exposure to endocrine disrupting chemicals and adverse neurological outcomes. In the preparation of this review, a PubMed literature search was conducted using the words \"endocrine disruptors,\" \"neuroendocrine effects,\" \"neurobehavioral effects,\" and \"neurodevelopmental effects\" and articles containing relevant studies were examined. Recent studies have shown a strong correlation between exposure to endocrine disrupting chemicals and the development of neurodegenerative diseases such as Alzheimer's and Parkinson's disease, and neurodevelopmental diseases such as autism spectrum disorder and attention deficit hyperactivity disorder. The effects of common pollutants such as pesticides, bisphenol A, polychlorinated biphenyls, and heavy metals on the endocrine system have been especially emphasized. In conclusion, understanding the role played by endocrine disrupting chemicals in the development of neurological diseases will be of critical importance in the development of new strategies to prevent these diseases.",

However, the hierarchy of these detrimental events remains unclear. It is well established that a-synuclein can induce calcium overload through diverse mechanisms. To assess whether calcium overload plays a crucial detrimental role, we established a calcium overload model in Drosophila and conducted genetic screening. Our findings indicate that calcium overload caused mitochondrial damage and lysosomal dysfunction, leading to cell death, and these cytotoxic processes were significantly mitigated by the loss of Tousled-like kinase (TLK). Notably, the loss of TLK also ameliorated defects induced by a-synuclein overexpression in Drosophila. This suggests that calcium overload is a critical event in a-synucleinopathy. In mammalian cells and mice, calcium overload activated TLK2 (the homologue of Drosophila TLK) by enhancing TLK2 phosphorylation, which increases TLK2 kinase activity. Increased TLK2 phosphorylation was detected in the brains of GluR1Lc and a-synuclein overexpression mice, suggesting that TLK2 is activated under these pathological conditions. Furthermore, TLK2 knockout mice exhibited rescue of multi-aspect cytotoxicity induced by calcium overload and a-synuclein overexpression. Our research demonstrates that TLK2 activation by calcium overload appears to be a pivotal step in the progression of PD. This finding provides a potential link between calcium overload, the subsequent mitochondrial and lysosomal dysfunction observed in the disease.",

Growing evidence identifies chronic neuroinflammation-particularly NLRP3 inflammasome activation in microglia-as a central driver for PD onset and progression. Misfolded \u03b1-synuclein, mitochondrial dysfunction, and environmental toxins act as endogenous danger signals that prime and activate NLRP3 inflammasome, leading to caspase-1-mediated maturation of IL-1\u03b2 and IL-18 and subsequent pyroptotic cell death. Impaired mitophagy, due to defects in PINK1/Parkin pathways or receptor-mediated mechanisms, permits accumulation of dysfunctional mitochondria and release DAMPs, thereby amplifying NLRP3 activity. Studies demonstrate that promoting mitophagy or directly inhibiting NLRP3 attenuates neuroinflammation and protects dopaminergic neurons in PD models. Autophagy-inducing compounds, along with NLRP3 inhibitors, demonstrate neuroprotective potential, though their clinical translation remains limited due to poor blood-brain barrier penetration, off-target effects, and insufficient clinical data. Additionally, the context-dependent nature of mitophagy underscores the need for precise therapeutic modulation. This review summarizes current understanding of inflammasome-mitophagy crosstalk in PD, highlights major pharmacological strategies under investigation, and outlines its limitations. Future progress requires development of specific modulators, targeted delivery systems, and robust biomarkers of mitochondrial dynamics and inflammasome activity for slowing PD progression.",

Although iron is an essential element, excessive amounts produce toxicity. Here, we focused on the role of iron and ATP13A2, the causative gene of PARK9 neurodegeneration with brain iron accumulation, using a cellular model. ATP13A2 deficiency resulted in impaired lysosomal function and iron accumulation in cell organelles. Further, we found dysfunction of mitophagy, which is involved in managing mitochondrial quality, as well as mitochondrial damage. Furthermore, we confirmed a decreased heme synthesis capacity, which is important to maintain intracellular iron homeostasis. Overall, our study indicates that lysosome-derived mitochondrial impairment can disrupt intracellular iron homeostasis in a cell model of PD pathology. This could help better understand the mechanisms underlying PD.",

Clinical data from 120 PD patients and 120 controls were analyzed. MPTP-induced PD mice and LPS-stimulated BV2 microglia models were used. In vivo, mice were divided into control, PD, and PD + Irisin groups for behavioral and histological assessments. In vitro, LPS-stimulated BV2 cells were treated with irisin or PBS. RNA sequencing, immunohistochemistry, and Western blot evaluated autophagy, inflammation, and ubiquitination pathways. PD patients exhibited increased TNF-\u03b1 and IL-1\u03b2 but decreased irisin levels. In PD mouse models, irisin improved motor deficits, increased nigrostriatal neuron numbers, restored tyrosine hydroxylase expression, and reduced \u03b1-synuclein aggregation. It also suppressed microglial inflammation and promoted anti-inflammatory polarization. Mechanistically, irisin enhanced autophagic flux, regulated RAGE ubiquitination mediated by PAFAH1B1, and inhibited neuroinflammation via the TFEB-NLRP3 axis. Specifically, PAFAH1B1 regulated RAGE expression through K61 and K169 sites on K48-linked polyubiquitin chains. Additionally, irisin restored lysosomal function by promoting TFEB nuclear translocation, enhancing NLRP3 inflammasome degradation, and reducing inflammatory factor secretion, thus alleviating neuroinflammation. Irisin alleviates PD pathology by modulating autophagy and ubiquitination pathways, suggesting its potential as a novel immunomodulatory target for PD.",

Despite their pervasive presence in indoor air, household dust, and the human body, these fibrous MNPs have received considerably less attention than polystyrene-based particles, resulting in a critical gap in our understanding of their potential health impacts. This review examines the growing evidence that textile-derived MNPs can translocate across biological barriers following inhalation or ingestion, reaching the brain via both direct olfactory pathways and systemic circulation through the blood-brain barrier. Experimental studies increasingly implicate MNPs in oxidative stress, neuroinflammation, and protein aggregation, processes central to the pathogenesis of neurodegenerative disorders such as Alzheimer's and Parkinson's disease. We also explore the therapeutic potential of natural bioactive compounds, including polyphenols and omega-3 fatty acids, in mitigating MNP-induced neurotoxicity. By consolidating current findings, this review highlights the urgency of advancing mechanistic studies, exposure assessment, and regulatory oversight to address the emerging threat of textile-derived MNPs to neurological health.",

The etiology of PD is multifactorial, involving both genetic and environmental factors. Pesticide exposure has been associated with PD, and with thousands of registered pesticides in the United States, it is still unclear which of these chemically and structurally diverse pesticides confer this association. The population-based case-control Parkinson's, Environment, and Gene (PEG) study based in the California Central Valley, an agricultural hub servicing much of the nation, offers a promising opportunity to investigate this relationship and identify likely environmental risk factors contributing to PD risk. In this study, 62 pesticides with reported agricultural use in the Central Valley were independently evaluated in 2 cell-based assays testing for pesticides that promote \u03b1-syn transmission and alter autophagy. To further stratify and prioritize pesticide candidates, pesticides that were positive in the 2 cell-based screens (double hits) were filtered through a newly described pesticide-wide association analysis to agnostically identify relevant real-world exposures. Using these selection criteria, 6 pesticides were identified as triple hits and were tested for dopaminergic neurotoxicity in an in vivo zebrafish (ZF) model. Of these 6 pesticides, 4 pesticides contributed to aminergic neuron loss in ZF larvae. The majority of the pesticides identified in our screens have not previously been implicated as risk factors for PD but should be considered in future studies.",

MPs/NPs enter the organism through ingestion, inhalation, and skin contact, subsequently accumulating in multiple organs-particularly the brain. Increasing experimental and epidemiological evidence implicates MPs/NPs in the development of Parkinson's disease (PD). Preclinical research models indicate that MPs/NPs may accelerate both the initiation and progression of PD by facilitating \u03b1-synuclein misfolding and aggregation, triggering neuroinflammatory cascades, elevating oxidative stress, and impairing mitochondrial function. To further investigate the causal role of MPs/NPs in PD, upcoming studies should emphasize well-designed, large-scale prospective cohorts to assess individual exposure to plastic-related pollutants, elucidate the pathways of MPs/NPs into the central nervous system, establish safety thresholds for their neurotoxicity, explore the correlation between exposure levels and central nervous system accumulation, clarify the temporal relationship between MPs/NPs accumulation and PD pathology and symptom onset, and identify the neuropathological mechanisms triggered by relevant concentrations of MPs/NPs.

Activating Transcription Factor EB (TFEB), a master regulator of lysosomal biogenesis and autophagy, has therefore emerged as a promising therapeutic strategy to enhance cellular clearance in these conditions. In this study, we identified KHS-101 as a novel TFEB activator through a high-throughput screen of blood-brain-barrier-permeable small molecules. We demonstrated that KHS-101 promotes TFEB nuclear translocation, enhances lysosomal biogenesis and proteolytic activity, and increases autophagic flux. Furthermore, KHS-101 significantly accelerates the degradation of pathogenic A53T mutant \u03b1-synuclein in a cellular model of Parkinson's disease, suggesting its potential to mitigate \u03b1-synuclein-mediated proteotoxicity and hold neuroprotective potential.

        "41622607": "ID: 41622607\nTitle: Zinc-Mediated Lysosomal Destabilization Links Mitochondrial Damage to Neuronal Death in a Cellular MPP+ Model of Parkinson's Disease.\nAbstract: Dysregulation of autophagy and lysosomal function is central to Parkinson's disease (PD), yet the upstream mechanisms leading to lysosomal failure remain unclear. Across primary mouse cortical neurons, MT-3 deficient primary mouse astrocytes, human iPSC-derived midbrain dopaminergic neurons, and Rho0 CHO cells lacking mitochondrial respiration, we investigated how mitochondrial stress perturbs zinc (Zn2+) homeostasis and lysosomal integrity. We identify intracellular zinc as a critical mediator linking mitochondrial dysfunction to lysosomal membrane permeabilization (LMP) and neuronal death. Inhibition of mitochondrial complex I by 1-methyl-4-phenylpyridinium (MPP+) elevated reactive oxygen species (ROS) and intracellular zinc, jointly driving LMP. Blocking either ROS or zinc markedly attenuated lysosomal damage and cell death, demonstrating that both act upstream of LMP. To define zinc regulation, we examined metallothionein-3 (MT-3), a brain-enriched zinc-binding protein. MT-3-deficient astrocytes were more vulnerable to MPP+ and zinc overload (ZnCl2) but paradoxically resistant to hydrogen peroxide (H2O2), suggesting that MT-3 buffers cytosolic zinc during mitochondrial injury or extracellular zinc influx yet can release bound zinc under oxidative conditions. Using Rho0 cells, we show that MPP+ toxicity depends on mitochondrial ROS, as loss of mitochondrial function nearly abolished cell death. However, Rho0 cells were highly sensitive to ZnCl2 and H2O2 and exhibited markedly reduced lysosomal abundance, indicating limited capacity to sequester zinc and increased susceptibility to zinc-mediated injury. These findings support a coordinated system in which lysosomes and zinc-binding proteins maintain zinc homeostasis. When cytosolic zinc rises, its accumulation within lysosomes induces LMP and accelerates cell death. Collectively, our results identify intracellular zinc as an upstream trigger of lysosomal dysfunction and neurodegeneration. Zinc-mediated LMP provides a mechanistic link between mitochondrial injury, impaired autophagic flux, and \u03b1-synuclein pathology in PD. Enhancing zinc homeostasis and lysosomal resilience may offer promising therapeutic strategies.",

Phosphorylation signaling pathways have been increasingly recognized as critical modulators in the development and progression of PD. Meanwhile, short-chain fatty acids (SCFAs), primarily produced by gut microbiota, have shown considerable neuroprotective potential by promoting autophagy, alleviating mitochondrial dysfunction, and regulating neuroinflammatory responses. Recent research suggests that SCFAs may influence the phosphorylation dynamics of key signaling pathways, including MAPKs, NF-\u03baB, JAK/STAT, PI3K/Akt, AMPK, and Nrf2/Keap1/ARE, thereby modulating disease pathophysiology. This review aims to systematically evaluate how SCFAs modulate phosphorylation pathways to influence neuroinflammation, \u03b1-synuclein aggregation, and mitochondrial dysfunction in PD.

The removal of a-synuclein aggregation through autophagy-lysosome pathway is a promising strategy for PD treatment. Transcription factor EB (TFEB) is a master regulator of autophagic and lysosomal biogenesis and function. Here, we report a library screen of intracellular Ca2+ inducers to identify small-molecule agonists of TFEB and discover MONNA can promote autophagic and lysosomal activity. Notably, MONNA facilitates the reduction of pathological a-synuclein in the Parkinson's disease model both in vitro and in vivo, and ameliorates PD-like behaviors in zebrafish. Mode of action studies reveal MONNA induces TFEB nuclear translocation through a Ca2+-dependent mechanism involving Calcineurin (CaN). Endoplasmic reticulum (ER) but not lysosome Ca2+ is critical to MONNA-induced TFEB activation and autophagy induction. Furthermore, Sarcoendoplasmic reticulum calcium ATPase (SERCA) pump of ER modulates TFEB nuclear translocation induced by MONNA. Our findings demonstrate that MONNA is the first ER Ca2+-dependent small synthetic TFEB agonist promoting the degradation of a-synuclein aggregates and alleviating Parkinson's disease. This ER Ca2+-Calcineurin-TFEB signaling pathway would broaden the way to develop drugs for PD.",

This review synthesizes evidence that MNPs translocate the blood-brain barrier (BBB) and induce neurotoxicity through mechanisms including oxidative stress, neuroinflammation, mitochondrial dysfunction, and neurotransmitter disruption. In rodent models, these disturbances lead to pathological and behavioral deficits relevant to neurodegeneration, neurodevelopmental disorders, and psychiatric conditions. Critically, we evaluate emerging clinical studies confirming the presence of MNPs within human central nervous system tissues and fluids. Our review then provides a critical appraisal of these human studies, highlighting their methodological limitations and inconsistent application of quality assurance/quality control (QA/QC) protocols, which currently constrain robust exposure assessment and causal inference. While clinical correlations exist between MNP levels and markers of BBB integrity, cognitive function, and stroke severity, establishing causality requires standardized detection methods and rigorous QA/QC integrated with longitudinal cohort studies.

However, the specific involvement of lysosome-related genes (LRGs) in PD remains unclear. This study aims to identify biomarkers specific to PD that exhibit robust disease prediction capabilities. Datasets for patients with PD, LRGs, and inflammation-related genes (IRGs) were retrieved from online databases. miRNAs and mRNAs within key modules were selected through Weighted Gene Co-expression Network Analysis (WGCNA), revealing strong associations with PD. A miRNA-mRNA network was constructed based on highly correlated PD-related LRGs (PD-LRGs) and miRNAs within these modules. Candidate genes were identified by intersecting target genes, differentially expressed genes (DEGs), PD-LRGs, and module-associated mRNAs. Machine learning and expression validation were employed to confirm these biomarkers. A nomogram was established, and its diagnostic performance was evaluated using a confusion matrix. Drug predictions were conducted based on these biomarkers. Spearman's correlation analyses were performed to assess the relationship between IRGs, freezing of gait (FOG)-related genes, and biomarkers. Molecular regulatory networks were constructed using datasets and online resources. Finally, clinical samples were collected for quantitative PCR (qPCR) validation of biomarker expression. Key modules related to PD were identified, comprising 190 miRNAs and 7,633 mRNAs. A miRNA-mRNA network was constructed based on 55 PD-LRGs and 181 miRNAs, resulting in the identification of 26 candidate genes strongly linked to lysosomal function. FGD4 and MAN2B1 were selected as biomarkers, and a gene expression-based risk prediction table was created. These biomarkers were significantly correlated with IRGs and several FOG-related genes. Gene localization analysis revealed that FGD4 and LRRK2, both critical to the FOG pathway, are located on chromosome 12. Drug prediction revealed that Tetrachlorodibenzodioxin and bisphenol A target both FGD4 and MAN2B1. qPCR analysis confirmed that FGD4 and MAN2B1 expression levels were significantly higher in patients with PD compared to healthy controls (p < 0.05). FGD4 and MAN2B1 act as lysosomal biomarkers associated with PD and exhibit strong correlations with genes involved in PD-related freezing of gait.

Ingestion via contaminated food and water is the primary exposure route, resulting in the accumulation of MNPs in key organs such as the gastrointestinal tract (GI), liver, and pancreas, highlighting the urgent need to understand their potential cumulative and systemic effects. This review critically evaluates recent molecular-level insights into the physiological impacts of MNPs, with particular emphasis on the GI system and the intricate gut-brain axis. MNPs induce cellular toxicity through oxidative stress (OS) and mitochondrial dysfunction, which activate inflammatory and apoptotic pathways. Accumulation in the GI tract causes gut microbiota dysbiosis and a compromised intestinal barrier, and translocates systemically to the liver and pancreas, leading to hepatotoxicity, insulin resistance, and chronic inflammation. Crucially, the disruption of the gut barrier facilitates MNPs access to the central nervous system (CNS) via the gut-brain axis, leading to a breach of the Blood-Brain Barrier. CNS-accumulated MNPs induce neuroinflammation and neurotoxicity, accelerating neurodegenerative disorders such as Parkinson's, Alzheimer's, and multiple sclerosis. This review elucidates the complex mechanisms and highlights significant gaps in understanding MNPs risks, which are currently limited by the use of short-term animal and in vitro models, as well as a lack of precise human data. Future research should prioritize the development of standardized quantification techniques and advanced tracking methods to accurately assess the biodistribution, metabolism, and long-term health effects of MNPs. This approach will facilitate the development of targeted therapeutic interventions and preventive measures.",

Despite decades of research emphasizing the enhancement of the cellular defense pathway, disease-modifying treatments remain elusive. We evaluated rotating magnetic field (RMF) therapy in A53T transgenic mice harboring a familial PD-associated mutation. Transgenic and wild-type animals (n\u2009=\u20098 per group) received RMF treatment (4\u00a0Hz, 0.4 T, 2\u00a0h daily) for six months. Motor function, muscle strength, and neuropathological markers were assessed. Comprehensive transcriptomic and proteomic analyses were performed to elucidate the molecular mechanisms involved. Untreated A53T transgenic mice exhibited progressive motor decline (51% reduction in locomotor activity, 39% decrease in muscle strength) accompanied by the accumulation of pathological \u03b1-synuclein aggregates. RMF-treated transgenic mice demonstrated significant functional recovery, with 78% wild-type locomotor activity and 80% normal muscle strength, with a marked reduction in \u03b1-synuclein pathology. Molecular profiling revealed unexpected suppression of hyperactivated stress response pathways, including mTOR signaling, autophagy, and oxidative stress responses (NES = -2.05 to -2.65, FDR\u2009<\u20090.01), whereas metabolic defense mechanisms such as glutathione biosynthesis were increased (NES\u2009=\u20092.18, FDR\u2009<\u20090.001).These findings suggest that normalization of aberrant stress signaling through RMF therapy represents a novel disease-modifying strategy with potential applicability to other neurodegenerative disorders characterized by proteostasis dysfunction.",

Over the past two decades, there has been a substantial acceleration in the knowledge of how genetics underlies PD risk. This has given rise to pathological protein targets that can be therapeutically targeted. In particular, there is compelling evidence for developing therapeutic strategies targeting alpha-synuclein, leucine-rich repeat kinase 2 (LRRK2) and glucocerebrosidase (GCase). These proteins are implicated in lysosomal function and may contribute to the accumulation of the hallmark pathological forms of alpha-synuclein that define PD. This review highlights current progress on PD therapies targeting these proteins as they attempt to make their way through the clinical trial pipeline, with unique and distinctive approaches being used for each target. Progress is being made in both immunotherapy and small molecule approaches to reduce aggregated forms of alpha-synuclein in the brain, with the aim to stop the propagation of disease. Pathogenic mutations in LRRK2 result in overactivation of the enzyme's catalytic kinase activity, and consequently kinase inhibitors that aim to reduce LRRK2 activity are in late phase clinical trials. In contrast, PD-associated mutations in GCase generally result in impaired lysosomal GCase activity, and thus small molecule chaperones and allosteric activators of GCase are in advanced development and clinical trials. Although these approaches seem to be generally tolerated by participants in phase I studies, challenges remain in progressing these promising therapies through phase II and beyond.",

GBA1 variants affect the glucocerebrosidase (GCase) enzyme, often leading to reduced GCase activity and associated altered lysosomal function, implicated in PD pathogenesis. Ambroxol, a small molecule widely used for respiratory diseases, has emerged as a potential therapeutic agent for PD, acting by increasing GCase activity. A phase 2 trial demonstrated ambroxol's safety and efficacy in penetrating cerebrospinal fluid (CSF) and engaging with its target in PD patients, including those with GBA1 variants. We present the protocol of the ASPro-PD trial, a phase 3, multicentre, randomised, double-blind, placebo-controlled trial, aimed at evaluating whether high-dose ambroxol improves motor and non-motor function in PD patients. The trial will enrol 330 PD patients with confirmed GBA1 status and the primary outcome will be the combined score of parts I, II, and III of the Movement Disorders Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS). The secondary outcomes include safety, impact on PD symptoms, and quality of life. Mechanistic and exploratory outcomes include biomarkers related to GCase activity, blood, and CSF biomarkers.

However, the neurotoxicity mechanisms triggered by polystyrene microplastics (PS-MPs) have yet to be elucidated. This study explored the damage induced by PS-MPs to the intestinal and central nervous system (CNS) and the potential mechanism. The results showed that PS-MPs exhibited size-dependent bioaccumulation with enhanced barrier penetration at submicron scales (500 nm > 1 \u03bcm \u226b 5 \u03bcm). Paradoxically, 1 \u03bcm PS-MPs demonstrated maximum neuroinflammation despite inferior biodistribution to 500 nm particles. Mechanistically, both sizes induce gut dysbiosis-mediated barrier disruption, elevating circulatory LPS that translocates across compromised BBB. This triggers excessive activation of the TLR4/MyD88/NF-\u03baB pathway, subsequently inducing a surge in pro-inflammatory cytokines, ultimately leading to synaptic lesions in the hippocampal region. Our findings established smaller PS-MPs (\u22641 \u03bcm) as latent neurodegeneration risk factors, demanding urgent assessment of chronic exposure consequences.",

While the accumulation of \u03b1-synuclein in neurons is implicated in the pathogenesis of these disorders, the mechanisms underlying \u03b1-synuclein mRNA degradation remain poorly understood. RNautophagy is a lysosomal RNA degradation pathway in which RNA is directly taken up into lysosomes and subsequently degraded. SIDT2, a lysosomal membrane protein, mediates the uptake of RNA. In this study, we investigated whether SIDT2-mediated RNautophagy degrades \u03b1-synuclein mRNA. Knockdown of SIDT2 led to reduced degradation of \u03b1-synuclein mRNA, whereas overexpression of wild-type SIDT2 enhanced its degradation, suggesting its role in \u03b1-synuclein mRNA turnover. In contrast, overexpression of the RNA uptake-deficient S564A mutant did not enhance degradation, indicating that RNA uptake activity is required for SIDT2-mediated degradation of \u03b1-synuclein mRNA. Using a series of deletion mutants, we identified a guanine (G)-rich sequence within the 5' untranslated region (5'-UTR) of \u03b1-synuclein mRNA as a key determinant of SIDT2-dependent degradation. Furthermore, insertion of the G-rich sequence into the 5'-UTR of GFP mRNA promoted SIDT2-dependent degradation of GFP mRNA and reduced GFP protein expression. Taken together, these results indicate that SIDT2-mediated RNautophagy contributes to the degradation of \u03b1-synuclein mRNA via the G-rich region within the 5'-UTR. Our findings may also provide insights into the pathogenesis of Lewy body diseases.",

MPs/NPs could traverse epithelial and endothelial barriers, disrupt the gut microbiota, and perturb the microbiota-gut-brain axis, leading to systemic inflammation and possibly extending neurodegenerative processes. Experimental models now demonstrate that MPs/NPs reprogram nuclear and mitochondrial epigenetics-DNA methylation, histone modifications, non-coding RNAs, and mitochondrial DNA regulation-in gut, immune, and neural cells with downstream effects on synaptic function, neuronal survival, and protein aggregation. This mechanistic narrative review integrates preclinical and emerging human evidence of how MPs/NPs compromise intestinal barrier integrity, modulate gut microbiota composition, affect the blood-brain barrier, and converge on oxidative stress, neuroinflammatory signaling, and cell death pathways within the central nervous system across key neurodegenerative diseases. Overall, the review offers an integrated model in which environmental exposure to chronic MPs/NPs disrupts the microbiota-gut-brain axis and drives concurrent nuclear and mitochondrial epigenetic remodeling, lowering the threshold for neurodegeneration in susceptible individuals, while outlining candidate mechanistic readouts that require exposure-specific validation in human-relevant models and longitudinal cohorts.",
        "41751935": "ID: 41751935\nTitle: Pathophysiological Roles of Two Intracellular P-Type ATPases: The Cancer-Associated Na+,K+-ATPase \u03b13 Isoform and the Parkinson's Disease-Related ATP13A2.\nAbstract: P-type ATPases constitute a diverse superfamily of ATP-driven transporters essential for ion homeostasis, membrane asymmetry, and organelle function. Among them, the P2-type Na+,K+-ATPase and the P5-type ATP13A2 have recently emerged as key regulators of cancer progression and neurodegeneration, respectively. In this review, we highlight new insights into the pathological roles of the Na+,K+-ATPase \u03b13 isoform (\u03b13NaK) in malignant cells and ATP13A2 in Parkinson's disease (PD). Cancer tissues frequently overexpress \u03b13NaK which is aberrantly localized to intracellular vesicles and undergoes adhesion-dependent intracellular trafficking. Upon cell detachment, \u03b13NaK translocates to the plasma membrane to sustain survival signaling, thereby promoting anoikis resistance and facilitating the persistence of circulating tumor cells (CTCs). Cardiac glycosides selectively inhibit \u03b13NaK at nanomolar concentrations, suppressing cancer cell proliferation through GLUT1 endocytosis, metabolic inhibition, and downregulation of THADA and LAT1, ultimately inducing anoikis in CTCs and reducing metastasis in vivo. Conversely, ATP13A2 is genetically linked to early-onset parkinsonism and regulates lysosomal integrity, polyamine homeostasis, and neuronal resilience. Recent animal studies demonstrate that adult-onset ATP13A2 loss causes progressive nigrostriatal degeneration, while heterozygous deficiency produces distinct age-dependent cognitive and \u03b1-synuclein phenotypes. Beyond its established role in polyamine transport, emerging evidence suggests that ATP13A2 can function as an H+,K+-ATPase-like transporter, contributing to proton and cation handling within the endolysosomal system. Together, these findings underscore the broader physiological and pathological significance of intracellular P-type K+-ATPases and highlight \u03b13NaK and ATP13A2 as promising therapeutic targets in cancer metastasis and PD.",

Genetic mutations in upstream regulators of cellular pathways, such as LRRK2, VPS35, TMEM230, and PINK1, are increasingly implicated in dysregulating Rab8a GTPase function, potentially disrupting its roles in \u03b1Syn homeostasis, lysosomal clearance, autophagy, membrane trafficking, lipid metabolism, and ciliogenesis. Rab8a protectively interacts with S129-phosphorylated \u03b1Syn to promote the formation of less toxic aggregates, whereas its depletion impairs lysosomal function and \u03b1Syn degradation. Gain-of-function LRRK2 and VPS35 mutations phosphorylate Rab8a at threonine 72 (Thr72), exacerbating PD pathology. In contrast, loss-of-function TMEM230 mutations have been linked to reduced Rab8a levels in some models, impairing vesicular trafficking and autophagy, whereas loss-of-function PINK1 mutations abolish serine 111 (Ser111) phosphorylation in a PINK1-dependent manner. This loss of phosphorylation impairs Rab8a activation (via reduced Rabin8 GEF binding) and removes a regulatory constraint on pathogenic LRRK2-mediated Thr72 phosphorylation. In vivo, LRRK2 and PINK1 mutations mechanistically converge on striatal ciliogenesis defects, reducing glial-derived neurotrophic factor (GDNF) signaling and neuroprotection. Although preclinical data strongly implicate Rab8a dysregulation as a downstream effector of multiple PD-associated genetic pathways, direct evidence of altered Rab8a expression or phosphorylation in human PD brain tissue is currently lacking. This review emphasizes the emerging role of Rab8a in PD pathogenesis and highlights its therapeutic potential.",

Emerging evidence highlights a crucial interplay between mitochondrial dysfunction and disrupted lipid homeostasis as central mechanisms driving PD pathogenesis. This scoping review synthesises current evidence on the relationship between mitochondrial dysfunction and neuronal lipid dysregulation in PD and identifies potential therapeutic targets within these intersecting pathways. Following the PRISMA-ScR guidelines, a comprehensive literature search was conducted across PubMed, Embase, and Web of Science for studies published between 2015 and 2025. Two independent reviewers screened and selected eligible studies based on predefined inclusion criteria. Analysis revealed four central interconnected pathological mechanisms: ferroptosis, alpha-synuclein-lipid interactions, mitochondrial dysfunction, and impaired autophagy/mitophagy. These mechanisms collectively contribute to oxidative stress, membrane destabilisation, and bioenergetic collapse, driving dopaminergic neuronal vulnerability. The findings underscore a complex, bidirectional relationship between mitochondrial dysfunction and lipid dysregulation in PD. Therapeutic strategies targeting iron accumulation, lipid peroxidation, and alpha-synuclein aggregation are promising. However, further mechanistic studies are required to clarify these interactions and advance the development of effective disease-modifying interventions.",

Herein, we engineer a near-infrared-II (NIR-II) phototheranostic nanoplatform, CAG/FD1080@MM-aTRPV4, for synergistic regulation of microglial function and real-time monitoring of PD pathology. We first encapsulated cycloastragenol (CAG), a bioactive compound derived from Astragalus, into liposomes. These liposomes were then fused with biomimetic microglial membrane-loaded FD1080 photothermal imaging agent, followed by modification with a transient receptor potential vanilloid 4 (TRPV4)-targeting antibody. In vitro studies using \u03b1-syn-treated cultured microglia and in vivo studies in an \u03b1-syn-overexpressing mouse model collectively demonstrate the efficacy of our strategy. It not only enables precise microglial delivery of CAG to reprogram metabolism but also sustains lysosomal function via photothermal activation of the TRPV4/CaMKK\u03b2/AMPK/mTOR pathway, ultimately enhancing phagocytosis. Importantly, the encapsulated FD1080 (for microglial tracking) and an anti-\u03b1-syn-conjugated indocyanine green (anti-\u03b1-syn-ICG) probe enable dual-modality NIR-II photoacoustic-fluorescence imaging, allowing real-time visualization of both microglial dynamics and \u03b1-syn clearance. This work pioneers a photothermal immunomodulation strategy using a Chinese herb-derived compound, presenting a versatile theranostic platform and novel mechanistic insights for microglia-targeted PD therapy.",

Here, we employed high-resolution untargeted lipidomics to map brain lipid perturbations in Drosophila melanogaster chronically exposed to polystyrene nanoplastics (PS- NPs). PS-NPs accumulated in fly brains and induced dose-dependent remodeling of mitochondrial membrane lipids, notably cardiolipins and phosphatidylethanolamines, accompanied by increased diacylglycerols/triacylglycerols and monounsaturated fatty acids and by lipid droplet expansion. Guided by these lipidomic signatures, targeted biochemical assays demonstrated depolarized mitochondrial membrane potential, elevated mitochondrial reactive-oxygen species, inhibition of respiratory-chain complexes I and IV, and a shift in NAD(H) and NADP(H) redox couples toward a reduced state and increasing lipid peroxidation. This redox imbalance was accompanied by decreased tyrosine-hydroxylase expression, dopamine depletion, and impaired locomotor behavior, hallmarks of Parkinson's disease (PD)-like neurodegeneration. Dopaminergic neurochemistry was impaired (tyrosine hydroxylase and dopamine decreased), with concomitant reduction of GABA, and locomotor and circadian deficits emerged. Remarkably, co-treatment with the antioxidant N-acetylcysteine (NAC) restored mitochondrial membrane potential, reduced mitochondrial ROS and lipid peroxidation, normalized neutral lipid and MUFA accumulation, and rescued neurotransmitter levels and behavior. Stable-isotope tracing confirmed disrupted TCA cycle flux after NPs exposure that was rescued by NAC. Collectively, these findings reveal lipidomic remodeling as a critical link between environmental NPs exposure and PD-like pathology, highlighting mitochondrial redox-lipid interactions as early determinants and support redox-directed interventions to mitigate risk.",

Although 10%-15% of PD cases are due to familial mutations, the remaining cases are sporadic, often linked to various factors, like pesticides and metals. For example, rotenone and dopamine are known to be involved in PD pathology and are suggested to cause changes in \u03b1-Syn protein homeostasis, although the mechanism by which they influence \u03b1-Syn and cellular toxicity is largely unknown. In this work, we demonstrate that both dopamine and rotenone promote the LLPS of \u03b1-Syn. Although rotenone promotes the liquid-to-solid transition almost instantaneously, dopamine, however, maintains a liquid state for a long time and rather delays the solidification process, unlike \u03b1-Syn alone. Similarly, exposure to both toxicants resulted in faster LLPS in SH-SY5Y cells. Interestingly, irrespective of their impact on material properties, rotenone promotes the faster formation of oligomers and amyloid fibrils, while dopamine exhibits oligomer formation and delayed fibrillation, both of which result in higher cytotoxicity. Our results provide new insight into the molecular processes underlying PD by indicating that endogenous dopamine stress and environmental toxicants converge on phase-separation dynamics as a common mechanism of \u03b1-Syn pathology.",

Its pathogenesis is complex, and the crosstalk among genetic factors, microenvironmental factors and neuroinflammation has emerged as a central research focus at present. Triggering receptor expressed on myeloid cells 2 (TREM2), a key regulator of microglial function, is deeply implicated in the pathophysiological processes of PD by mediating multiple biological events, including phagocytic clearance, inflammatory homeostasis, autophagy regulation and neuronal repair. In recent years, Advances in genomics, cell biology and model animal technologies, the genetic association between TREM2 gene variants and PD, the regulatory role of the TREM2 signaling pathway in \u03b1-Syn pathological propagation, and its dual effects in neuroinflammation and dopaminergic neuron protection have been gradually elucidated. This review systematically summarizes the molecular structure and signal transduction mechanisms of TREM2, with a focus on elaborating the multidimensional roles of the TREM2 signaling pathway in the regulation of \u03b1-Syn metabolism, microglial polarization, dopaminergic neuron survival and non-motor symptoms in PD. We also conduct an in-depth analysis of the pathological significance of TREM2 gene variants and their interactive effects with microenvironmental factors, and discuss therapeutic strategies and research progress for PD targeting the TREM2 signaling pathway. Finally, we summarize the current research controversies and future directions, aiming to provide new insights into the mechanistic investigation and precision therapy of PD.",

Combined use of these drugs resulted in a decrease in the levels of lysosphingolipids, triggering alpha-synuclein oligomerization, as well as a decrease in the levels of monomeric and neurotoxic phosphorylated (Ser129) alpha-synuclein and an increase in tyrosine hydroxylase.

To study the mechanisms underlying this phenomenon, we developed a microfluidic BBB model (mBBB) using human cerebral microvascular endothelial cells (HCMECs) in direct contact with primary human astrocytes and pericytes within a physiologically relevant extracellular matrix. The horizontal architecture enables high-resolution imaging across the full barrier interface and allows direct assessment of nanoparticle transport and accumulation. This in vitro platform recapitulates key features of the BBB, including selective permeability, junctional protein expression, and receptor-mediated uptake pathways. Using this system, the trafficking and accumulation of structurally distinct nanoparticles, including liposomes, nanoplastics, and extracellular vesicles (EVs), were compared. Among these, heterologous EVs exhibit the highest transport efficiency. Analysis of nanoparticle properties suggest that ligand presentation and membrane composition, rather than size or stiffness, primarily govern BBB penetration. The mBBB platform provides a high-throughput, imaging-based framework to systematically interrogate nanoparticle trafficking across the BBB and offers a translational tool for both drug delivery and neurotoxicity screening.",
        "41863649": "ID: 41863649\nTitle: Molecular mirror: reflecting the complexity of Parkinson's disease.\nAbstract: Parkinson\u2019s disease (PD) is a multifaceted neurodegenerative disorder driven by a complex interplay of genetic and environmental factors that disrupt normal cellular function. A hallmark of PD pathology is the abnormal accumulation of alpha-synuclein protein, leading to the formation of Lewy Bodies and the degeneration of dopaminergic neurons. Critical proteins like Akt1 and glycogen synthase kinase-3 beta (GSK-3\u03b2) are vital for cell survival and apoptosis regulation; their dysfunction adversely affects the health of dopaminergic neurons, accelerating neurodegeneration. Additionally, PARK2 (parkin) and PTEN-induced kinase 1 (PINK1) are crucial for mitochondrial function and energy homeostasis. In PD, mutations in these genes are reported and impair mitochondrial quality control, making neurons more vulnerable to stress and exacerbating disease progression. The enzyme glucocerebrosidase (GBA), crucial for lysosomal function, is also linked to PD, with mutations in the GBA gene associated with increased SNCA accumulation and faster disease progression. Interestingly, tau protein, typically associated with Alzheimer\u2019s Disease, is also present in Parkinson\u2019s disease pathology, suggesting a potential overlap in the mechanisms driving these neurodegenerative diseases. The vesicular monoamine transporter 2 (VMAT2) plays a crucial role in dopamine regulation, and its malfunction can render dopaminergic neurons more vulnerable to degeneration. In conclusion, PD represents a complex interplay of genetic, protein-related, and environmental factors leading to progressive neurodegeneration. Understanding these molecular mechanisms is crucial for developing biomarkers and advanced therapies. Ongoing research is essential for creating treatments that effectively manage symptoms, slow disease progression, and improve patient quality of life, ultimately transforming the lives of those affected.",

While diverse toxic effects of BHPF have been documented in the literature, its effects on neurons, potential neurotoxicity, and underlying molecular mechanisms remain unclear. In this study, we reported that BHPF (10, 25\u202f\u00b5M) inhibited neuronal SH-SY5Y cell viability, increased lactate dehydrogenase (LDH) release, and induced cell death in a dose-dependent manner. BHPF exposure increased intracellular reactive oxygen species (ROS) and mitochondrial reactive oxygen species (mtROS) levels, decreased mitochondrial membrane potential, reduced the expression of cytochrome C oxidase subunit 4 (COX4) and mitochondrial protein 1 (MFN1), but upregulated Bax, Caspase-3, Caspase-8 and initiated apoptosis. In addition, BHPF treatment led to the accumulation of acidic vacuoles in the cells and increased the expression of autophagy regulatory proteins, including Beclin-1, LC3II, ATG5 and p62. Moreover, BHPF could trigger endoplasmic reticulum stress (ER stress), and ER stress inhibitor taurodeoxycholate (TUDCA) reversed the BHPF-induced oxidative stress, apoptosis and autophagy. Thus, our in vitro data indicate that ER stress may be linked to the oxidative stress, apoptosis, and autophagy observed in nerve cells following BHPF exposure. These findings offer preliminary insights into cellular processes that could help elucidate the potential role of nerve cells in BHPF-associated degenerative diseases.",

Notwithstanding its reputation as a safer alternative, emerging data indicates that BPF may produce similar or even more pronounced toxicological consequences. This study found that adult zebrafish exposed to environmentally relevant concentrations of BPF displayed significant anxiety-like behaviour, diminished cognitive performance, and decreased scototaxis preference, indicating increasing neurobehavioral dysfunction. These behavioural changes suggest that prolonged BPF exposure disrupts neuronal circuit integrity and emotional regulation. Biochemical tests indicated a significant decline in total antioxidant capacity, coupled with diminished activities of catalase and superoxide dismutase, as well as increased levels of lipid peroxidation. This array of alterations indicates significant oxidative stress and impaired antioxidant defence mechanisms in the zebrafish brain. At the molecular level, a duration-dependent activation of the MKK4/7-JNK-c-Jun signalling cascade was noted, aligning with the onset of pro-apoptotic MAPK pathways under oxidative circumstances. Supporting these findings, histological evaluations verified significant neuronal loss and chromatin condensation, especially in the periventricular grey matter, a region essential for adult neurogenesis. Collectively, our findings suggest that extended exposure to BPF triggers oxidative stress-mediated apoptotic signalling, resulting in neurodegeneration and notable behavioural deficits. This study highlights the pressing necessity to reevaluate the environmental safety and regulatory oversight of BPF, considering its widespread application and proven ability to impair vertebrate neurological health.",

However, the synergistic toxicity of Ps-MPs and PBDEs on female fertility and oocyte quality remains insufficiently characterized. In this study, we established a 28-day oral exposure model in female ICR mice to evaluate the effects of Ps-MPs, PBDE-47, and their co-exposure on ovarian function, oocyte meiotic competence, and reproductive outcomes. Both Ps-MPs and PBDE-47 alone reduced ovarian weight, decreased antral follicles, increased follicular atresia, and markedly lowered ovulation and litter size, whereas co-exposure produced the most severe impairments. At the oocyte level, exposure significantly reduced germinal vesicle breakdown and first polar body extrusion, increased abnormal spindle formation and erroneous kinetochore-microtubule attachments, and suppressed TPX2 expression and \u03b1-tubulin acetylation. Cortical F-actin polarization, spindle migration, and membrane localization of JUNO and ovastacin were also disrupted, indicating widespread defects in meiotic and membrane maturation. Mechanistically, Ps-MPs and PBDE-47 induced a decline in mitochondrial membrane potential, aberrant mitochondrial distribution, excessive lipid accumulation, and Ca\u00b2\u207a imbalance, accompanied by autophagosome accumulation, lysosomal dysfunction, elevated ROS, increased \u03b3-H2AX signals, and enhanced Annexin V labeling, ultimately triggering DNA damage and apoptosis. All alterations were most pronounced under co-exposure. Collectively, Ps-MPs and PBDE-47 synergistically impair female fertility by converging on mitochondrial dysfunction, autophagy-lysosome imbalance, and oxidative stress-mediated DNA damage, leading to substantial reductions in oocyte quality. These findings provide key mechanistic evidence for evaluating reproductive risks associated with real-world mixtures of microplastics and persistent organic pollutants.",

This triggers severe cellular dysfunction, including endoplasmic reticulum (ER) stress and the dysregulation of the unfolded protein response (UPR). TMBIM6, an anti-apoptotic ER protein, inhibits the UPR sensor IRE1a. Although TMBIM6 exhibits neuroprotective effects in neurological disorders, its role in PD-related DAergic neuron survival remains unknown. We report that TMBIM6 mRNA is increased in cellular models exposed to 6-hydroxydopamine (6-OHDA), rotenone, or aSyn preformed fibrils (PFFs), whereas TMBIM6 protein levels are elevated in postmortem PD SNpc, indicating translational relevance. Modulating TMBIM6 expression in DAergic cells and primary neurons showed that knockdown increased aSyn toxicity, while overexpression is protective. Single-cell RNA-seq analysis of PD SN revealed selective disruption of TMBIM6 co-expression with key UPR effectors (HSPA5, ERN1, and XBP1), and reduced TMBIM6 levels in vulnerable DAergic neurons. Mechanistically, TMBIM6 directly binds IRE1a, and aSyn PFFs disrupt this complex, leading to IRE1a activation; genetic or pharmacological IRE1a inhibition prevented cell death in TMBIM6-deficient cells. In vivo, TMBIM6 downregulation in Drosophila melanogaster worsens rotenone-induced DAergic neuron degeneration and motor impairments, while adeno-associated virus (AAV)-mediated TMBIM6 overexpression in mice improves motor function and neuron survival. Our results demonstrate that TMBIM6 modulates ER stress responses, promoting DAergic neuron survival by regulating IRE1a activity. Consequently, the TMBIM6/IRE1a axis represents a promising therapeutic target for mitigating neurodegeneration in PD and related disorders.",

These processes lead to the formation of pathological proteins, resulting in the brain diseases called synucleinopathies, tauopathies or TDP-43 proteinopathies. There is currently growing support for the hypothesis that genetic variants explain a significant fraction of the etiology of apparently sporadic parkinsonian disorders. Genetic risk factors can be stratified according to the metabolic or structural processes that can lead to cellular disturbance;\u00a0these processes involve protein aggregation, protein and membrane trafficking, stabilization of the neurite structure, prion-like transmission of pathological proteins, ubiquitin-proteasome system balance, mitophagy, lysosome autophagy, synaptic functions, and dopamine transmission. Regarding the environmental risk factors, there are several substances that have been supposed of being a risk for the development of neurodegenerative proteinopathy and Parkinsonism, mainly the agents used in agriculture and the textile industry. The most important and most frequently studied are pesticides and trichlorethylene. Beside the globally ubiquitous substances which are supposedly neurotoxic and exposure to which can cause manifestations of Parkinsonism, there are more geographically (regionally) specific substances, which cause (or quite recently caused) the manifestation of endemically present Parkinsonism.

However, most of the developed aggregated \u03b1-synuclein-specific degraders, e.g., autophagy-targeting chimeric peptides, are limited by the blood-brain barrier (BBB), substantia nigra (SN) neuron targetability, and intracytoplasmic release. To overcome these obstacles, we constructed an engineered exosome (EXO) equipped with surficial glucose-regulated protein 94 (GRP94)-targeting peptide N, luminal \u03b1-synuclein-degrading peptide P1, and cathepsin-B-cleavable GFLG as the linker between the exosome skeleton protein and P1, termed NEXOGFLG-P1. We verified that the NEXOGFLG-P1 exosomes could cross the BBB and target diseased SN neurons in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (MPTP)-induced PD model mice. Following fusion with endosomes, the exposed P1 was released into the cytoplasm by cytoplasmic cathepsin B-mediated GFLG cleavage to degrade \u03b1-synuclein. Collectively, the NEXOGFLG-P1 exosomes exhibit a significant degradation effect on \u03b1-synuclein aggregates, providing a proof-of-concept platform for treating PD. STATEMENT OF SIGNIFICANCE: Targeted degradation of \u03b1-synuclein aggregates holds tremendous potential for the etiological treatment of Parkinson's disease (PD). However, most of current \u03b1-synuclein-specific degraders are stuck with low blood-brain barrier permeability, poor targetability for diseased cells, and uncontrolled release. Notably, \u03b1-synuclein predominantly affects neurons in the substantia nigra (SN) region rather than the whole brain. To overcome these obstacles, we constructed an engineered exosome, termed NEXOGFLG-P1, to specially deliver and release autophagy-targeting chimeric peptide to degrade \u03b1-synuclein in the diseased SN neurons through the autophagy-lysosomal pathway. The engineered exosomes exhibit the great potential in targeting diseased SN neurons and degrading \u03b1-synuclein aggregates, providing a proof-of-concept therapeutic platform for treating PD.",

Mitochondrial dysfunction and impaired protein degradation pathways are thought to play critical roles in PD progression, contributing to the loss of dopaminergic neurons in the substantia nigra. Phosphorylation of \u03b1-synuclein has been shown to promote its aggregation, underscoring its potential role in disease progression. Parkin, an E3 ubiquitin ligase, is widely regarded as a pleiotropic neuroprotective protein that modulates the mitochondrial quality control, as well as metabolic turnover and the accumulation of \u03b1-synuclein. Death-associated protein kinase 1 (DAPK1), which is involved in the regulation of apoptosis and autophagy, has recently emerged as an important factor in neurodegeneration. While DAPK1 has been implicated in Alzheimer's disease through its role in tau aggregation and amyloid-\u03b2 production, our findings suggest that DAPK1 may also influence PD-related pathways by phosphorylating parkin at Ser136 and Ser198. This phosphorylation promotes the mitochondrial transport of parkin, enhancing interaction with mitochondria-localised E3 ubiquitin ligase MITOL and consequently leading to the degradation of parkin. Given the neuroprotective role of parkin, its reduction increases the vulnerability of neurons to 6-hydroxydopamine-induced toxicity, potentially contributing to decreased neuronal survival. Together, these findings suggest that DAPK1 functions as a previously unrecognised modulator of parkin and could potentially influence PD-related neurodegenerative processes. This pathway may provide a mechanistic link between mitochondrial dysfunction, \u03b1-synuclein pathology and neuronal cell death.",

In addition, anionic nanoplastics can induce vascular endothelial leakiness, thereby harboring a paracellular route for their systemic and cerebral access. Yet causality remains unproven in implicating nanoplastics for neurodegeneration in the absence of standardized human exposure data, mechanistic specificity, and epidemiological evidence, especially considering the supra-environmental doses employed.

        "41957923": "ID: 41957923\nTitle: Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?\nAbstract: The enteric nervous system (ENS), a key component of the gut-brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)-a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or environmental contamination. Emerging evidence suggests that FCs may initiate or amplify neurodegenerative processes, yet their effects on the ENS and their impact in gut-to-brain communication remain insufficiently characterized. This systematic review synthesizes current evidence on FCs-induced effects on the ENS and its involvement in mediating neurotoxicity from dietary toxicants exposure. Following PRISMA guidelines, 67 studies were included pertaining to cellular or mammalian experimental models exposed to FCs via enteral routes, reporting ENS-related outcomes or studying vagal involvement in modulating FC toxicity. The main FCs evaluated were pesticides, toxins, bisphenols, acrylamide, manganese, and micro-/nanoplastics. Across studies, FCs consistently induced neurochemical remodeling of the ENS, activation of enteric glia, often coupled with intestinal alterations. Rotenone, paraquat, and polystyrene micro-/nanoplastics promote \u03b1-synuclein aggregation within the ENS and its vagal propagation to the brain. Vagotomy models confirmed that disrupting ENS-CNS communication attenuates FC-related central neurotoxicity, supporting the involvement of food toxicants in gut-to-brain propagation of neurotoxic signals. These findings support the body-first hypothesis of PD and position the ENS as a critical, yet underinvestigated interface in exposome-related neurotoxicology. The review highlights research gaps and the need for improved models and long-term, low-dose studies reflecting realistic FC exposure.",

Key drivers of neuroinflammation include glial cell reactivity, cytokine signaling, protein aggregation, and mitochondrial dysfunction. Although animal models have been extensively used to investigate the mechanisms, their translational relevance is limited because neuroinflammation in humans is typically chronic, heterogeneous, and sustained over years, whereas in rodents is often acute, transient, and resolves within days to weeks. This paper highlights the utility of human stem cell-derived models in studying Parkinson's disease by recapitulating patient-specific genetic mutations, neuroinflammatory microglia-neuron interactions, \u03b1-synuclein aggregation, and dopaminergic dysfunction, thereby enabling mechanistic studies in the human-relevant models. In addition, we examine how micro- and nanoplastics may exacerbate neuroinflammation in PD. This review concludes by highlighting how human-relevant stem cell-based approaches advance mechanistic understanding of Parkinson's disease.",

Copper is an essential redox-active metal in the central nervous system (CNS), but alterations in its homeostasis can promote oxidative stress, mitochondrial dysfunction, and proteostatic failure. In vitro studies indicate that copper can promote \u03b1-synuclein misfolding, enhance oxidative stress, and interfere with both the ubiquitin-proteasome system (UPS) and the autophagy-lysosome pathway (ALP). In this review, we critically evaluate mechanistic evidence from cellular models, integrating available animal and clinical data to assess the biological significance of copper-mediated impairment of \u03b1-synuclein clearance. We highlight the current research, identify methodological limitations, and discuss whether copper imbalance acts as a primary pathogenic trigger or as a disease-modifying amplifier of proteostatic failure. Furthermore, we consider the translational implications of selectively modulating intracellular copper pools as a therapeutic strategy in PD. Finally, we will highlight unresolved issues, methodological limitations, and emerging targeted therapeutic prospects.",

However, the precise toxicological mechanisms remain elusive. Our results demonstrated that MPs triggered mitochondrial dysfunction and mitochondrial ROS (mtROS) accumulation, which subsequently activated NLRP3/caspase-1/GSDMD-N-dependent pyroptosis in hepatocytes. Notably, beyond its canonical translocation to the plasma membrane, GSDMD-N was observed to form pores on the mitochondrial outer membrane, exacerbating mitochondrial damage. The mitochondrial GSDMD-N pores amplified mtROS overproduction, triggering lysosomal membrane permeabilization (LMP) and facilitating lysosomal iron efflux, which ultimately initiated ferroptosis. Concurrently, mitochondrial GSDMD-N mediated mitochondrial intrinsic apoptosis by promoting cytochrome c release and caspase-3 activation. Collectively, our findings revealed that MPs induced GSDMD-N activation and its mitochondrial translocation, which in turn initiated pyroptosis, ferroptosis, and apoptosis in hepatocytes. This study provided novel mechanistic insights into MPs-induced hepatotoxicity, identifying GSDMD-N as a potential central hub coordinating multiple cell death modalities.",

Increasing evidence indicates that chronic inflammation and immune dysregulation are central to its pathogenesis. The activation of microglia, astrocytes, and circulating monocytes establishes a self-perpetuating cycle of inflammation and neuronal injury, positioning monocytes as a key interface between systemic and central immune responses. MAIN TEXT: The discovery of misfolded alpha-synuclein in peripheral tissues, such as the gut, olfactory mucosa and skin, supports a multisystem view of the disease, suggesting that peripheral pathology may precede and drive neurodegeneration through neuroanatomical and microbiota-mediated routes. Monocytes exhibit altered subset composition, impaired phagocytic capacity, and metabolic reprogramming involving mitochondrial and lysosomal dysfunction, partly linked to mutations in the LRRK2 and GBA1 genes, which further sustain inflammation and alpha-synuclein aggregation. In parallel, the disruption of the blood-brain and meningeal barriers facilitates immune cell infiltration and amplifies neuroinflammatory signalling within the brain. Elevated circulating cytokines, chemokines, and inflammasome activation reflect a primed immune state correlated with disease progression, whereas metabolic disturbances in tryptophan, purine, lipid, and microbiota-derived pathways connect peripheral metabolic imbalance to neuronal vulnerability. Finally, exosomes act as critical mediators of communication between the periphery and the brain. Owing to their ability to cross the blood-brain barrier bidirectionally, they contribute to the dissemination of alpha-synuclein and transport miRNAs that promote oxidative stress, two key mechanisms underlying Parkinson disease pathology. These features position exosomes as both promising targets for biomarker discovery and effective vehicles for the targeted delivery of therapeutic agents to the central nervous system. CONCLUSIONS: Together, this review highlights peripheral inflammation and misfolded alpha-synuclein as pivotal contributors to neuroinflammatory mechanisms in Parkinson disease, emphasizing monocyte-related pathways as promising targets for disease monitoring and intervention.",

Despite significant advances in understanding \u03b1-SYN self-assembly, the precise sequence of early aggregation steps has not been directly visualized in living neurons. Here, we use an optogenetic-induced protein aggregation system with a high temporal resolution to monitor the onset of \u03b1-SYN assembly in neurons. We found that the initiation and accumulation of \u03b1-SYN aggregates occur predominantly at the lysosomal membrane, an event driven by the \u03b1-SYN N-terminus and modulated by the membrane-associated adaptor protein WD repeat-containing protein 44 (WDR44). Remarkably, we demonstrate that WDR44 knockdown markedly reduced de novo \u03b1-SYN aggregation in both neuronal cultures and in vivo, whereas WDR44 overexpression enhances \u03b1-SYN aggregation in PD patient-derived iPSC neurons. Consistent with its potential pathogenic involvement, WDR44 aberrantly accumulates in vivo and in the brains of PD patients, where it colocalizes with LB inclusions. Finally, we show that lysosome-associated \u03b1-SYN aggregates compromised lysosomal structure and function, leading to neuronal impairment, a phenotype worsened by WDR44 overexpression, linking early aggregation events to downstream toxicity. Together, these findings reveal the earliest dynamic stages of \u03b1-SYN oligomerization in living neurons and identify the WDR44-\u03b1-SYN interaction as a promising therapeutic target for reducing \u03b1-SYN pathology and enabling early intervention in PD.",

Lewy bodies- the defining neuropathological hallmark of PD-are chiefly composed of aggregated forms of \u03b1-synuclein (\u03b1-syn). Despite the widespread presence of \u03b1-syn pathology, neurodegeneration is often selective, and the mechanisms underlying the vulnerability of specific neuronal populations in PD remain poorly understood. This review critically evaluates \u03b1-syn-based models of PD, with a focus on murine systems, to determine how they have illuminated the cellular and molecular determinants of neuronal susceptibility. Across murine \u03b1-syn pathology models, degeneration reliably affects dopaminergic neurons (TH+) in SNpc, with preferential vulnerability of aldehyde dehydrogenase 1 family member A1- (ALDH1A1-) neurons in the dorsal SNpc, as well as noradrenergic and cholinergic (ChAT+) neurons, and parvalbuminergic interneurons, depending on the experimental context. In these models, degeneration is accompanied by mitochondrial and lysosomal dysfunction, calcium dysregulation, presynaptic failure, and neuroinflammatory activation. This review integrates transcriptomic and proteomic data across murine \u03b1-synuclein models, revealing differences in selective neuronal vulnerability across models depending on spatiotemporal context and interplay between intrinsic neuronal properties and extrinsic factors. This review paper underscores the need for stage-resolved mapping of vulnerable neuronal and non-neuronal populations in PD and, as well as careful alignment of model selection with the specific mechanistic questions under investigation. It also highlights the need for further single cell and spatiotemporally resolved in vivo studies using reliable molecular markers.",

This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA.",

As an environmental endocrine disruptor, DEHP impairs male reproductive function. Its metabolite, mono-(2-ethylhexyl) phthalate (MEHP), mediates many toxic effects, but the mechanisms remain unclear. We hypothesized that DEHP induces testicular necroptosis through MEHP-mediated calcium overload and the RIPK1-regulated lysosomal-mitochondrial axis. Here, we reveal this novel mechanism. This study investigated DEHP-induced testicular damage, focusing on necroptosis and calcium (Ca\u00b2\u207a) signaling pathways. Sprague-Dawley rats were exposed to 250 and 750\u202fmg/kg DEHP for 5 weeks. Testicular damage was assessed via histopathology, testosterone measurement, and RNA sequencing (RNA-seq). A common Sertoli cell line was treated with MEHP to study Ca\u00b2\u207a overload, lysosomal membrane permeabilization (LMP), mitochondrial dysfunction, and necroptosis. Pharmacological inhibitors were employed to explore pathway involvement, including CA-074 Me (cathepsin B inhibitor), BAPTA-AM (Ca\u00b2\u207a chelator), and Nec-1 (RIPK1 inhibitor). DEHP caused testicular damage, including seminiferous tubule disorganization and reduced plasma testosterone. RNA-seq revealed necroptosis pathway enrichment, with upregulated RIPK1, RIPK3, MLKL, and PGAM5. MEHP induced Ca\u00b2\u207a overload, LMP, and mitochondrial dysfunction in Sertoli cells. CA-074 Me attenuated mitochondrial damage, while BAPTA-AM mitigated LMP. Nec-1 suppressed necroptosis-related proteins and restored blood-testis barrier integrity by upregulating ZO-1, Cx-43 and Claudin-11. DEHP exposure induced testicular necroptosis via MEHP-mediated Ca\u00b2\u207a overload-lysosomal-mitochondrial axis, regulated by RIPK1. These findings provide insights into DEHP reproductive toxicity.",

Although nanoplastics are ubiquitous and intractable in the environment and in organisms, their potential health impacts remain unclear. Emerging evidence showed that nanoplastics can cross the blood-brain barrier and accumulate in the brain. However, the effects of nanoplastics on neuronal health and functions in the brain are poorly understood. Here, we examined the effects of nanoplastic exposure on neurotransmitter release by measuring FM 4-64 (a lipophilic styryl dye) release from synaptic vesicles during electrical stimulation after exposing rat hippocampal neurons to 1-10 \u03bcg/mL of fluorescent polystyrene nanoplastics with an average diameter of 42 nm. We found that nanoplastics accumulated in the presynaptic terminal of hippocampal neurons and reduced stimulation-induced FM 4-64 release in a dose-dependent manner. Furthermore, nanoplastics decreased Ca2+ elevation in the presynaptic terminal of hippocampal neurons during electrical stimulation. Our results suggest that accumulated nanoplastics in the brain can impair neuronal functions by disrupting neurotransmitter release and Ca2+ dynamics in the presynaptic terminal of neurons, which could eventually lead to neurodegeneration.",

However, their combined neurotoxic effects, particularly in the context of climate change-driven temperature rise, remain unexplored, posing a critical knowledge gap for environmental health risk assessment. To address this gap, we developed a mouse model subjected to coexposure to heat stress (36 \u00b0C, 4\u202fh/day) and well-characterized polystyrene nanoplastics (PS-NPs, 60\u202fnm, 10\u202fmg/kg/day) for 30 consecutive days. Multidisciplinary approaches, including behavioral testing, histopathological analysis and molecular profiling, were employed to assess cognitive dysfunction and its underlying mechanisms. Compared with the single-exposure groups, coexposure induced pronounced cognitive deficits in mice, which were concomitant with hippocampal neurodegeneration, bloodbrain barrier (BBB) compromise, and exacerbated hippocampal oxidative stress. Transcriptomic profiling and subsequent validation revealed a novel role for oxidative stress-induced NLR family pyrin domain containing 6 (NLRP6) inflammasome activation in driving microglial pyroptosis, which exacerbates neuroinflammation through a feedforward loop. The administration of the antioxidant N-acetylcysteine (NAC) attenuated these pathological alterations by suppressing oxidative damage, thereby rescuing cognitive performance. This study elucidates a novel mechanism whereby heat stress and PS-NP coexposure synergistically disrupt neurological homeostasis via redox-sensitive inflammatory pathways, offering critical insights for the development of preventive strategies against combined environmental neurotoxicity.",

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation.",

Over the past decade, a rapidly expanding literature has identified galectins as regulators of microglial activation, misfolded protein pathology, vesicle damage sensing, autophagy, synaptic plasticity, myelination, vascular repair, and neuroimmune communication. Galectins operate across intracellular and extracellular compartments to integrate cellular stress and innate immune signaling. Here, we review CNS studies of galectin-1, galectin-3, galectin-4, galectin-8, and galectin-9, focusing primarily on work published from 2019 onward while incorporating selected earlier studies to establish foundational concepts. Across experimental models and human studies, galectins orchestrate microglial state transitions, regulate aggregation and propagation of amyloid-\u03b2, tau, \u03b1-synuclein, and mutant huntingtin, and function as intracellular sensors of vesicle and lysosomal damage. Multiple studies further establish galectins as biomarkers and therapeutic targets across Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, retinal degeneration, and chronic pain. Importantly, this review highlights a stage- and context-dependent paradox in which the same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others. Together, these findings position galectins as central regulators that convert intracellular stress into coordinated neuroimmune programs shaping proteinopathy, circuit dysfunction, and tissue remodeling.",

Here, we tested whether extracellular vesicles (EVs) enhance endothelial uptake, intracellular accumulation, and barrier disruption by polystyrene NPs (PSNPs). Human umbilical vein endothelial cells (HUVECs) were exposed to free PSNPs (100\u202f\u03bcg/mL) or PSNP-encapsulated EVs (PSNP-EVs; 1\u202fmg/mL EV protein) for 24\u202fh, with vehicle controls, and barrier function was evaluated in endothelial monolayers using transendothelial electrical resistance (TEER) and permeability assays. Notably, EV encapsulation prolonged intracellular retention of PSNPs and reduced cellular clearance compared with free PSNPs, with signals persisting up to 12\u202fh, whereas free PSNPs peaked at 4\u202fh and declined thereafter. In human endothelial monolayers, PSNP-EVs produced a larger decline in TEER than free PSNPs, resulting in a 2.8-fold greater TEER decline, and promoted macromolecule-permeable paracellular transport, selectively increasing 4-kDa (1.38-fold) and 40-kDa (3.07-fold) dextran permeability while leaving sodium fluorescein largely unchanged. PSNP-EV exposure reduced occludin and ZO-1 expression to 47.6% and 60.8% of control levels, respectively, and disrupted their continuous junctional localization, indicating destabilization of the occludin-ZO-1-actin scaffold. Pharmacologic inhibition of dynamin-mediated endocytosis with dynasore reduced EV uptake by 69.3% and prevented PSNP-EV-induced TEER loss. In vivo imaging further revealed brain accumulation and persistence of administered PSNP-EVs. Collectively, these results indicate that EVs promote sustained accumulation of nanoscale plastics within endothelial cells and the brain, concomitant with increased macromolecular paracellular permeability of the BBB and a heightened neurovascular risk.",

Exposure to contaminants such as bisphenol A (BPA), phthalates, polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) during these critical windows can reprogram endocrine and neural circuits, resulting in persistent behavioral alterations. This review synthesizes mechanistic evidence from animal models and epidemiological studies linking developmental EDC/POP exposure to attention deficits, impulsivity, anxiety and altered reward sensitivity-phenotypes defined here as addiction vulnerability (addiction-relevant endophenotypes) rather than clinically diagnosed substance-use disorder (SUD). We propose a two-hit, adverse outcome pathway (AOP)-informed model in which prenatal EDC/POP exposure induces endocrine-related perturbations that prime reward and stress circuitry. Subsequent exposure to psychoactive drugs and/or chronic stress then acts on these sensitized systems to increase the probability of maladaptive reinforcement learning and impaired behavioral control. Mechanistically, early-life exposures disrupt thyroid and sex-steroid signaling, dysregulate the hypothalamic-pituitary-adrenal axis, and alter dopaminergic, serotonergic, and glutamatergic neurotransmission with additional modulation by epigenetic reprogramming, oxidative stress, and neuroinflammation. Human cohort studies consistently associate prenatal BPA and phthalate exposures with adverse neurobehavioral and externalizing symptoms in children, supporting this framework while underscoring the limited availability of longitudinal data linking early exposure to SUD outcomes. Integrating these findings within an AOP perspective highlights the importance of developmental timing, sex, dose, genetic background, and co-exposures, and supports risk-assessment strategies that account for sequential environmental and drug exposures.",

Increasing evidence demonstrates that MNPs are not confined to peripheral tissues but can accumulate even in the human brain, raising concerns about their potential contribution to neurological disease. This structured review synthesizes global trends in plastic production, environmental MNP burden, and human exposure, together with emerging data on brain accumulation, entry pathways, neurotoxic mechanisms, and key translational challenges. We present evidence showing that MNPs may cross brain barriers via multiple routes, including the blood-brain barrier, blood-cerebrospinal fluid barrier, olfactory, and circumventricular pathways, particularly under conditions of barrier vulnerability. Experimental studies reveal that once in neural tissue, MNPs may disrupt synaptic function, mitochondrial homeostasis, autophagy, and redox balance, while activating neuroinflammatory and gut-brain axis-mediated pathways. These mechanisms intersect with disease-relevant processes implicated in multiple neurological disorders whose global prevalence and societal burden have sharply increased over recent decades, including stroke, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, mood disorders, and neurodevelopmental conditions. Despite growing mechanistic plausibility, translational and human epidemiological evidence remains limited by methodological heterogeneity, a lack of standardized detection methods, and the absence of longitudinal clinical data/studies.

In this process, a set of non-coding RNAs including miRNAs, lncRNAs, and circRNAs form key regulatory layers in the pathogenesis of the disease and directly affect \u03b1-synuclein homeostasis, mitochondrial function, oxidative stress, neuroinflammation, autophagy, and proteostasis. Dysregulation of miRNAs targets neurosensitive pathways; miR-7 and miR-153 inhibit SNCA translation, miR-27a/b and miR-103a-3p regulate the PINK1/Parkin axis in mitophagy, and miR-155, together with miR-135b, modulate the regulation of the NF-\u03baB/NLRP3 dependent inflammasome. On a broader level, lncRNAs with destructive roles such as NEAT1, HOTAIR, MALAT1, SNHG1, UCA1 and GAS5 increase \u03b1-synuclein accumulation and impair autophagy through ceRNA and chromatin remodeling mechanisms. On the other hand, circRNAs with their stable circular structure alter posttranslational regulation through miRNA sponging; such that circSNCA, CDR1as and circSLC8A1 enhance \u03b1-synuclein load, impair mitophagy and exacerbate oxidative stress, while circDLGAP4 has a neuroprotective function.

Copper, an essential trace element, plays a role in \u03b1-synuclein aggregation and PD pathogenesis. This study examines the effects of copper overload on \u03b1-synuclein clearance pathways, focusing on autophagy and the ubiquitin-proteasome system (UPS) in dopaminergic SH-SY5Y neuroblastoma cells. Copper exposure enhances autophagosome formation, as indicated by increased Beclin-1 and LC3-II levels, and impairs autophagic flux, evidenced by LC3-II accumulation in the presence of chloroquine. Concurrently, copper increases polyubiquitinated proteins, suggesting UPS dysfunction, which is confirmed through MG132 treatment. These disruptions lead to the accumulation and aggregation of \u03b1-synuclein, particularly in its phosphorylated form. Immunofluorescence reveals neurite-localized \u03b1-synuclein aggregates, consistent with copper's role in \u03b1-synuclein pathology.

Betanin, a beetroot-derived small molecule, has exhibited antioxidant and neuroprotective properties. In this study, three betaxanthins-Bxn-A, Bxn-B, and Bxn-C-were chemically synthesized from betanin to enhance its therapeutic properties. Betaxanthin Bxn-A effectively reduced intracellular ROS levels without cytotoxicity, even at 500 \u00b5M. Additionally, betanin and its derivatives revealed neuroprotective effects, including significant reductions in apoptosis, preservation of mitochondrial membrane potential, modulated autophagy, and enhanced cell viability in PD-model cells. In terms of aggregation inhibition, betaxanthins Bxn-A and Bxn-B significantly reduced \u03b1SN aggregation compared to the control after 48 h of incubation. Betaxanthin Bxn-A also triggered disaggregation of existing aggregates and inhibited formation of large, insoluble species. Moreover, \u03b1SN aggregation and disaggregation products formed in the presence of betanin or its derivatives exhibited significantly lower cytotoxicity than those formed in their absence. Specifically, cells treated with aggregates formed in the presence of 50 \u00b5M betaxanthin Bxn-B showed 100% viability, while those treated with disaggregation products formed in the presence of 100 \u00b5M betaxanthin Bxn-A showed 20% greater viability than those treated with untreated disaggregates. Molecular docking revealed interactions between betaxanthins and key \u03b1SN residues, suggesting destabilization mechanisms. Docking analyses with five ROS-PPI network key proteins-C5, CDC42, BCL2, CDKN1A, and CDKN1B-indicated potential roles in inhibiting oxidative stress-related pathways. Drug-likeness predictions indicated that the derivatives enhanced pharmacological potential, making them promising candidates for PD treatment.",

We applied an integrative approach combining network toxicology, Mendelian randomization, molecular docking, and single-cell transcriptomics to identify BPA-responsive targets relevant to ischemic stroke. CX3CL1 was prioritized based on network centrality, genetic association with stroke risk, and endothelial enrichment in post-ischemic brain tissue. Functional validation was performed in bEnd.3 brain endothelial cells and an endothelial-astrocyte Transwell blood-brain barrier (BBB) co-culture model subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Under normoxic conditions, BPA (50 and 100\u202f\u03bcM) did not markedly reduce cell viability; however, it significantly aggravated OGD/R-induced injury. BPA increased endothelial apoptosis (10.1% and 21.2% vs. 4.6% under OGD/R alone), elevated CX3CL1 protein expression (1.71- and 2.28-fold vs. control), increased BAX, and reduced Bcl-2 levels. Tight junction proteins were substantially decreased (claudin-5: 0.49 and 0.24; ZO-1: 0.46 and 0.23 relative to control), accompanied by reduced transendothelial electrical resistance and increased FITC-dextran permeability. Pharmacological inhibition of CX3CR1 using AZD8797 (0.5\u202f\u03bcM) partially attenuated BPA-exacerbated apoptosis, tight junction loss, and barrier hyperpermeability without significantly altering CX3CL1 expression. Collectively, these findings suggest that BPA potentiates ischemia-reperfusion-associated endothelial and barrier dysfunction, accompanied by changes in CX3CL1-CX3CR1-related signaling, and support a potential role for environmental toxicants as modifiers of ischemic neurovascular vulnerability.",

As an emerging environmental pollutant, MPs can infiltrate the human body through multiple pathways, including inhalation, ingestion, dermal contact and bloodborne transmission.Correspondingly, MPs, which can penetrate the blood-brain barrier and enter the central nervous system (CNS), have been linked to the development of neurodegenerative diseases (NDs).In this review, we provide a comprehensive analysis of the environmental distribution of MPs, the pathways of entry into the human body, and the distribution within the CNS. Furthermore, we explore intrinsic factors influencing the neurotoxicity of MPs and elucidate the mechanisms underlying MPs-induced NDs, including Alzheimer's disease, Parkinson's disease, and Amyotrophic lateral sclerosis. Beyond mechanistic insights, we offer a novel perspective by exploring the potential adaptation of emerging environmental MPs detection and removal technologies for CNS applications. Ultimately, elucidating these mechanisms positions the reduction of MPs accumulation as a critical intervention point, highlighting the adaptation of environmental technologies as a promising strategy for the prevention and management of NDs.",

Over the past two decades, genetic discoveries have highlighted the convergence of multiple familial PD genes on the autophagy-lysosome pathway (ALP), a key cellular system responsible for the degradation and recycling of intracellular components. Recent studies have further revealed that components of the ALP not only mediate the clearance of \u03b1-synuclein aggregates but also, under certain pathological conditions, contribute to their propagation via lysosomal exocytosis or secretory autophagy. The precise functions of autophagy are highly context-dependent, with neuronal and glial cells exhibiting distinct ALP dynamics that shift with development, stress, and aging. In this review, we summarize current knowledge on the physiological regulation of autophagy in the brain and critically examine its involvement in PD pathogenesis, incorporating mechanistic insights from familial models and emerging evidence from sporadic PD. We also explore translational implications, focusing on efforts to identify ALP-related biomarkers in cerebrospinal fluid and urine, and on the therapeutic potential of modulating ALP activity. Although the causality between ALP dysfunction and PD remains elusive, mounting evidence supports its contribution to disease progression, particularly through impaired lysosomal homeostasis and disrupted intracellular trafficking. Future research should aim to define cell type-specific ALP alterations, clarify the bidirectional interactions between \u03b1-synuclein and autophagic machinery, and develop in vivo tools to monitor autophagy activity and secretory signatures. A deeper understanding of these processes will be crucial for refining PD models, discovering robust fluid biomarkers, and designing targeted therapies capable of modifying disease trajectory.",

In this study, we established a human-relevant polystyrene nanoplastics (PS-NPs, 50\u202fmg\u202fkg-1) oral exposure model in C57BL/6 mice in vivo and a neuro-immune microglial-neuron co-culture system (HMC-3/SH-SY5Y cells) in vitro to dissect these mechanisms. We demonstrate that PS-NPs exposure triggers microglial M1 activation and drives neuronal senescence. Mechanistically, PS-NPs activate the protein phosphatase 2A (PP2A)-B56\u03b3 subunit, which selectively dephosphorylates the ribosome biogenesis regulator ErbB3-binding protein 1 (Ebp1) at Ser335. This post-translational modification reduces Ebp1 nucleolar localization, suppresses 47S pre-ribosomal RNA transcription, and induces nucleolar stress. Consequently, the p53/p21 pathway is engaged, promoting neuronal senescence. Pharmacological inhibition of PP2A with LB-100 restored ribosome biogenesis, prevented neuronal senescence, and rescued cognitive deficits and neurodegenerative phenotypes in PS-NP-exposed mice. This is the first study to identify the PP2A-B56\u03b3-p-Ebp1Ser335-ribosome biogenesis axis as a novel cascade mechanism driving PS-NP-induced neuronal senescence. Our findings offer a targetable strategy to mitigate nanoplastics-associated neurodegeneration.",

This study reveals that 14-day exposure to 5\u2009\u03bcm polystyrene microplastics (PS-MPs) (500\u2009\u03bcg/L) induces neurocognitive impairment in rainbow trout (Oncorhynchus mykiss), a globally consumed aquaculture species. MPs accumulated in brain and gut tissues, causing blood-brain barrier structural alterations, intestinal mucosal damage, and oxidative stress. Multi-omics analysis revealed associations between gut microbiota dysbiosis (reduced Ralstonia, increased Acinetobacter) to suppressed neuroactive pathways, particularly GABA synthesis and transport. Downregulation of monocarboxylate transporters (mct1/2) and GABA-related enzymes (GAD1/2) disrupted gut-to-brain GABA homeostasis, neurobehavioral deficits. These findings establish the gut microbiota-GABA axis as a critical mediator of MPs neurotoxicity, highlighting risks to seafood safety and necessitating urgent regulation of microplastic contamination in aquatic food chains.",
        "42103223": "ID: 42103223\nTitle: The role of phospho-ubiquitin in mitochondrial health and diseases.\nAbstract: Mitochondria play a major role in cellular health, yet their contribution to chronic diseases has been underestimated. Mitochondria are essential for all tissues and are the major source of ATP in high-energy-demand organs such as brain and heart, which consequently are vulnerable to mitochondrial dysfunction. Failure to repair or remove damaged mitochondria contributes to aging and chronic diseases. Cells have evolved quality control mechanisms, including mitophagy to eliminate damaged mitochondria and mitobiogenesis to replenish them. The ubiquitin-proteasome system (UPS) is responsible for removing misfolded proteins, a process that is highly ATP dependent and therefore reliant on mitochondrial function. In turn, damaged mitochondria are eliminated through coordinated actions of the UPS and lysosomal degradation through mitophagy. Many neurodegenerative diseases are characterized by the presence of disease-specific protein aggregates, such as \u03b1-synuclein aggregates in Parkinson's disease and tau neurofibrillary tangles in Alzheimer's disease. These aggregates impair mitochondrial function, while dysfunctional mitochondria generate reactive oxygen species that further exacerbate proteotoxic stress, creating a pathogenic cycle. This highlights the functional interplay between mitochondria and the UPS. Recent studies have uncovered phosphorylation of ubiquitin at serine 65 by the mitochondrial kinase PINK1 as a key signal of mitochondrial dysfunction. Phospho-Ser65-ubiquitin (pUb) has emerged as an indicator of mitochondrial health and a potential biomarker for aging and neurodegenerative disease. However, due largely to a lack of tools, little is known about the role of pUb in cellular physiology. Here, we review the current landscape of pUb biology, the phospho-ubiquitome, and its role as biomarker for mitochondrial health and neurodegeneration.",

Sustained activation drives neuroinflammation, synaptic dysfunction, and neuronal loss, making NLRP3 a compelling therapeutic target. This review summarizes current insights into NLRP3 inflammasome biology in AD and PD, with emphasis on antibody-based interventions. Emerging delivery approaches, such as receptor-mediated transcytosis, nanoparticles, adeno-associated viral vectors, and magnetic resonance-guided focused ultrasound are also examined for their potential to enhance central nervous system (CNS) delivery of NLRP3-targeting antibodies. Antibody-based NLRP3 inhibitors offer high specificity and favorable safety profile compared with small-molecular-weight inhibitors; however, limited blood-brain barrier (BBB) penetration remains a major challenge. Advances in antibody engineering, modular bi-/multi-specific designs, and targeted CNS delivery platforms may soon enable the development of first-in-class antibodies capable of directly modulating neuroinflammation. To realize this potential, the field should prioritize: (1) developing BBB-penetrant antibody constructs; (2) integrating delivery technologies with target biology; and (3) accelerating translation toward first-in-human studies. Successful implementation could transform therapeutic strategies for AD and PD and extend antibody-based interventions across a broader spectrum of neuroinflammatory disorders.",

This review examines the molecular mechanisms by which lead, cadmium, mercury, arsenic, bisphenol A, phthalates, and dioxins modulate NLRP3 signaling. Lead and cadmium activate NLRP3 through mitochondrial dysfunction and oxidative stress, whereas mercury and arsenic suppress inflammasome assembly by preventing apoptosis-associated speck-like protein containing a CARD (ASC) oligomerization. EDCs engage receptor-mediated pathways: aryl hydrocarbon receptor (AhR) activation directly represses NLRP3 transcription, yet bisphenol A and phthalates override this suppression through NF-\u03baB activation. Developmental timing critically determines outcomes such as prenatal exposures epigenetically programing persistent NLRP3 dysregulation. Sex hormones have been shown to modulate distinct inflammatory landscapes: estrogen suppresses NLRP3 via ER\u03b2-dependent mechanisms, while testosterone amplifies inflammasome-dependent pathology. The skin serves as a primary interface for environmental chemical exposure and cutaneous NLRP3 activation. NLRP3-deficient mice exhibit 34% increased lifespan, and pharmacological inhibition with MCC950 extends lifespan in progeria models. The CANTOS trial demonstrated that targeting inflammation through IL-1\u03b2 neutralization confers cardiovascular benefits in high-risk humans. These findings position NLRP3 as a central integrator through which the chemical exposome accelerates inflammaging and identify inflammasome inhibition as a therapeutic strategy for environmental disease prevention.",

Despite being marketed as a safer alternative, the long-term impacts of BPS on neural function and behaviour remain poorly understood. This study investigated whether embryonic exposure to environmentally relevant concentrations of BPS induces persistent neurobehavioural, neurochemical, and molecular alterations in adult zebrafish (Danio rerio). Embryos were exposed to an environmentally relevant concentration of BPS (30 \u00b5g/L) from 4 to 120 h post-fertilization (hpf) and subsequently reared in clean water until 6 months of age. Adult behavioural assessments revealed that BPS-exposed fish exhibited significant deficits in social affiliation, spending less time in the conspecific zone during group preference testing. However, shoaling behaviour and anxiety-like responses in the novel tank test, including swimming speed and zone preference, remained unaffected. Neurochemical analysis showed a significant reduction in brain dopamine levels, while serotonin (5-HT) and acetylcholine (ACh) levels were unchanged. Oxidative damage was corroborated by a significant elevation of brain lipid peroxidation (LPO) following embryonic BPS exposure. Molecular profiling of adult brain tissues revealed alterations in genes associated with oxidative stress (gpx1a), apoptosis (p53, bax, casp3), neuroinflammation (tnf-\u03b1, il1b, ngfb), and neurotransmission, particularly within serotonergic (slc6a4b, htr1d, htr2b) and cholinergic (chata) pathways. These findings indicate that embryonic BPS exposure leads to persistent neurochemical and transcriptional changes that selectively impair adult social behaviour without broadly affecting anxiety or locomotion. These observations underscore the potential neurodevelopmental toxicity of BPS and the urgent need to re-evaluate its safety in aquatic environments.",

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology. Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters.",

Earthworms are key contributors to soil structure and nutrient cycling, and their molecular stress responses can provide an early indication of soil health impairment. Heat shock proteins are central to the stress response, and small heat shock proteins (sHSPs) are ATP-independent chaperones that limit stress-induced protein aggregation. Because their expression is stress-sensitive, sHSPs are promising molecular markers for soil stress and contributors to thermotolerance. Eisenia fetida, a widely used ecotoxicology model, relies on molecular chaperones like small heat shock proteins (sHSPs) for stress tolerance. We previously characterized sHSPs containing a single \u03b1-crystallin domain (ACD) in E. fetida. Here, we report the first identification of sHSPs containing two \u03b1-crystallin domains (ACDs) in annelid species. These genes were identified from an E. fetida transcriptome, their domain architecture was defined, and their transcriptional responses were quantified under heat stress, desiccation, and exposure to two pollutants (bisphenol A and endosulfan), including combined exposure with elevated temperature. Double-ACD sHSPs showed stimulus- and time-dependent transcriptional patterns. Moderate heat and desiccation primarily induced late (24\u00a0h) upregulation of several sHSP genes, whereas bisphenol A at optimal temperature did not result in significant transcriptional change and endosulfan produced only limited changes under single-stressor exposure. In contrast, combined exposure to endosulfan and elevated temperature triggered a significant upregulation of multiple sHSP genes, consistent with an additive stress effect. These results expand this protein family diversity in annelids and support a staged sHSP response in which structurally distinct sHSPs may contribute to resilience under prolonged or combined environmental stress.",

It is important with respect to neuron health, regulation of \u03b1-syn protein synthesis, and its degradation. Numerous cellular pathways implicated in the process of autophagy, chaperone, and proteolysis play a vital role in the maintenance of \u03b1-syn protein homeostasis. Autophagy dysfunction defeats \u03b1-syn protein accumulation and neuroinflammation, as present in dementia with Lewy bodies and sporadic PD. Oxidative stress is another key factor that intensifies \u03b1-syn protein misfolding and aggregation, thereby leading to neurodegeneration. Involvement in the treatment of \u03b1-syn related disorders includes passive and active immunization, inhibitors of protein aggregation, gene silencing technology, modulators of synaptic function, and target drug delivery systems. Other \u03b1-syn related therapy approaches include the development of a novel herbal formulation focusing on the gut-brain axis and interventions designed to enhance protein quality control. As clinical trials move forward, minimizing challenges related to the target involved, biomarkers, and patient stratification is crucial to decoding these therapies into effective management.

Recent evidence suggests that microplastic exposure may trigger such ferroptosis-related pathologies. However, the mechanism and impact of ferroptosis-induced cerebral cortex damage in waterfowl due to microplastic exposure remain unclear. In this study, Muscovy ducks were divided into three groups receiving: pure water, 1\u202fmg\u00b7L\u207b\u00b9\u202fpolyvinyl chloride microplastics (PVC-MPs), or 10\u202fmg\u00b7L\u207b\u00b9\u202fPVC-MPs for two months. This study suggests that PVC-MPs may accumulate in the duck cerebral cortical tissue, where they disrupt blood-brain barrier (BBB) integrity as manifested by ultrastructural damage and significant downregulation of tight junction protein levels (ZO-1, Occludin, and Claudin-5). Moreover, PVC-MPs exposure induced histopathological and nuclear ultrastructural damage, along with oxidative stress and excessive iron accumulation, both hallmarks of ferroptosis. Specifically, PVC-MPs triggered mitochondrial cristae fragmentation and shrinkage, as well as lipid peroxidation accumulation, evidenced by elevated MDA levels. Western blot analysis confirmed ferroptosis through significant downregulation of SLC7A11, GPX4, and FTH1, and upregulation of COX2. In conclusion, this study suggests that PVC-MPs may accumulate in the duck cerebral cortex, where they disrupt BBB integrity and induce histopathological damage, as well as disturb redox homeostasis and trigger ferroptosis, ultimately leading to neuronal injury.",

We have previously reported that the small GTPase Rab27b modulates autophagic-lysosomal function in neurons and supports lysosomal degradation of \u03b1syn across multiple \u03b1syn cellular models. Knockout (KO) and knockdown (KD) of Rab27b damage lysosomal degradative capacity and exacerbate \u03b1syn pathology, while Rab27b overexpression is conversely protective in cellular \u03b1syn models. Elevations of Rab27b seen in human synucleinopathies suggest a compensatory role for Rab27b in these disorders. Here, we examined the role Rab27b plays in vivo in the context of both A53T genetic \u03b1syn overexpression and viral AAV \u03b1syn overexpression mouse models. Rab27b knockout in A53T+ mice did not alter motor behavior or survival. However, Rab27b knockout increased proteinase-K resistant \u03b1syn in the cortex, striatum, and substantia nigra of A53T mice starting as early as six months of age. Additionally, Rab27b KO increased phosphorylated S129 \u03b1syn in the cortex and nigra. Astrocyte and microglial activation were also observed upon Rab27b KO in the A53T model. In the AAV \u03b1syn model, Rab27b KO resulted in dopaminergic cell loss in the nigra, which was not observed in WT mice.

However, it is known to cause reproductive toxicity in both humans and animal models. Curcumin, a polyphenolic compound from turmeric, is known for its potent anti-inflammatory and antioxidant effects. We previously showed that curcumin alleviates BPAF-induced apoptosis in caprine endometrial epithelial cells (EECs). However, the underlying mechanisms of BPAF toxicity remain unclear. The aim of this study was to investigate whether ferroptosis contributes to BPAF-induced injury in EECs and to assess the protective role of curcumin. We demonstrate that BPAF triggers ferroptosis in EECs: ferroptosis-related factors (COX2, FACL4, and NCOA4) were upregulated, and GSH content was increased. These effects were significantly reversed by the ferroptosis inhibitor Fer-1, which restored cell viability and reduced MDA accumulation. Mechanistically, BPAF-induced ferroptosis was autophagy-dependent, as evidenced by upregulated ATG5, Beclin1, and LC3, and enhanced autophagic flux. Inhibition of autophagy by CQ significantly attenuated ferroptosis and improved cell viability. Furthermore, ER stress acted as an upstream regulator, as its inhibitor 4-PBA alleviated both autophagy and ferroptosis. BPAF also disrupted cellular iron homeostasis by promoting NCOA4-mediated ferritinophagy, resulting in intracellular iron accumulation. Curcumin pretreatment alleviated BPAF-induced ferroptosis by suppressing ferritinophagy and restoring iron homeostasis. Moreover, activation of the PI3K/AKT/mTOR and Nrf2/HO-1 pathways may exert protective effects by suppressing autophagy and lipid peroxidation. In conclusion, this study indicates that ferroptosis is a key mechanism underlying BPAF-induced cytotoxicity in EECs. Curcumin protects against this damage by inhibiting ER stress and autophagy, providing a potential therapeutic strategy for BPAF-related uterine diseases.",

In this study, 30\u00a0days after hatching (dah) Nile tilapia were subjected to sub-chronic exposure to polystyrene microplastics (PS; 100\u00a0nm) for 14\u00a0days. Histopathological examination revealed evident inflammatory cell infiltration in the livers of PS-exposed fish compared to the control fish. Transmission electron microscopy showed elevated mitochondrial rupture and increased autophagosome formation. Immunofluorescence and Western blot analyses showed upregulated Lc3b and downregulated P62 protein levels, suggesting enhanced hepatic autophagy. Transcriptomic profiling of liver tissues and subsequent KEGG enrichment analysis highlighted significant upregulation of genes involved in the MAPK, NOD-like receptor, Toll-like receptor, and autophagy signaling pathways. Metabolomic profiling indicated notable enrichment in glutathione metabolism, ferroptosis, cysteine and methionine metabolism, and the NOD-like receptor pathway. Integrated transcriptomic and metabolomic KEGG analysis consistently identified ferroptosis as a centrally enriched pathway. Further gene expression and metabolite analyses demonstrated marked upregulation of immune-related genes, autophagy-related genes, and ferroptosis-pathway genes. Concurrently, ferroptosis-related metabolites including glutathione and cysteine were significantly decreased. Meanwhile, levels of lipid metabolites such as 2-oleoylglycerol were also reduced, whereas lipid peroxidation products represented by 4-hydroxynonenal were significantly increased. Additional validation confirmed increased expression of inflammatory factors (il-1\u03b2, tgf-\u03b2, nlrp3) and altered iron homeostasis in the PS-exposed fish liver. These findings indicate that sub-chronic PS exposure promotes hepatic ferroptosis via immune-mediated activation of autophagy, ultimately leading to liver injury in Nile tilapia. Our study provides novel insights into the mechanisms underlying microplastic-induced tissue damage in aquatic organisms.",

Conventional therapies, comprising levodopa and dopamine agonists, give symptomatic relief but fail to terminate disease progression and are associated with long-term complications. Relevant review papers and articles from the past were investigated. Certain factors, including early disease diagnosis, therapeutic efficacy in PD models, and predictive modeling of drug-nanoparticle interactions, were considered during the conduct of this research. This literature review is a comprehensive narrative of research articles obtained from various platforms, namely Scopus, PubMed, Google Scholar, and Research Gate.

Emerging evidence suggests that \u03b1-syn dysfunction may also affect peripheral organs, with chronic kidney disease (CKD) increasingly recognized as a potential comorbidity. This review critically examines current evidence on the molecular pathways linking PD and CKD through \u03b1-syn. \u03b1-Syn comprises an N-terminal lipid-binding domain, a non-amyloid component (NAC) region prone to aggregation, and a C-terminal domain that regulates conformational stability. Among the proposed mechanisms, mitochondrial dysfunction, oxidative stress, and impaired autophagy-lysosomal clearance represent the most consistently reported pathways across neuronal and renal systems, while activation of the renin-angiotensin system (RAS) has been implicated in more limited or context-dependent studies. Preclinical and limited clinical observations indicate that \u03b1-syn-associated processes may contribute to podocyte injury and fibrotic remodeling in renal tissue, whereas reduced \u03b1-syn expression has been suggested to compromise epithelial cell stability. These findings support the concept of a kidney-brain axis; however, the extent and directionality of this interaction remain incompletely defined. Novel \u03b1-syn-targeted therapies, including ENT-01, Cu(II)ATSM, ambroxol, and lipid-modulating strategies, are being investigated for their cross-organ efficacy, although most evidence currently derives from preclinical or early-phase studies. Importantly, key knowledge gaps persist, including the mechanisms underlying peripheral \u03b1-syn aggregation, the pathways of inter-organ communication, and the clinical validity of \u03b1-syn-based biomarkers. Overall, current evidence supports a potential role for \u03b1-syn as a contributing molecular link between neurodegenerative and renal dysfunction, rather than a definitive unifying mechanism, underscoring the need for integrated and evidence-driven diagnostic and therapeutic approaches.",
        "42154395": "ID: 42154395\nTitle: Plant-derived neuroprotective compounds and nanoformulations targeting Parkinson's disease: a semi-systematic review of mechanisms and therapeutic potential.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by aggregates of \u03b1-synuclein and the degeneration of dopaminergic neurons in the substantia nigra. Current pharmaceutical therapies mainly alleviate symptoms without halting disease progression. Evidence suggests that traditional plant-based interventions may serve as supplementary therapies by targeting oxidative stress, mitochondrial dysfunction, neuroinflammation, and apoptosis. This review explores the neuroprotective properties of ten medicinal plants commonly used in traditional medicine: Bacopa monnieri, Curcuma longa, Mimosa pudica, Zingiber officinale, Ocimum sanctum, Emblica officinalis, Camellia sinensis, Cannabis sativa, Panax ginseng, and Withania somnifera. A systematic and comprehensive search of PubMed, Scopus, and Web of Science identified relevant in vitro, in vivo, and clinical studies. This study highlights the mechanisms by which plant-derived chemicals influence cellular pathways associated with PD, emphasising their therapeutic potential despite limited clinical validation. Studies have shown that bioactive compounds such as curcumin, bacoside, Epigallocatechin-3-gallate (EGCG), cannabidiol, ginsenosides, and withanolides exhibit antioxidant, anti-inflammatory, anti-apoptotic, and neuroprotective effects in PD models. Nanotechnology offers promising strategy to enhance the efficacy of herbal compounds, addressing challenges of poor solubility, rapid metabolism, low bioavailability, and restricted blood-brain barrier penetration. Nano-delivery systems including liposomes, polymeric nanoparticles, nanoemulsions, and metal nanoparticles can improve stability, brain targeting, controlled release, and cellular uptake of these bioactives, thereby enhancing therapeutic efficiency while reducing systemic toxicity. Green-synthesized plant-based nanoparticles further provide synergistic neuroprotective benefits, positioning phyto-nanomedicine as a multi-target approach for PD therapy. However, extensive clinical studies are required to confirm safety and effectiveness.",

This evidence has prompted TRPML1 drug discovery efforts across academia and industry, with several small-molecule agonists advancing toward clinical development. In this review, we provide a comprehensive overview of the therapeutic potential of TRPML1 as a molecular target from a medicinal chemistry perspective. We summarize the structural basis of channel activation and inhibition, highlighting insights from recent cryo-EM studies that define the principal ligand-binding sites and mechanisms of allosteric modulation. We systematically survey the chemical space of TRPML1 ligands reported to date, including diverse agonist and antagonist chemotypes, and extend this analysis to encompass undisclosed or recently disclosed compounds emerging from industry pipelines. Furthermore, we discuss key determinants of ligand design and developability, including the challenges associated with targeting a deeply embedded, lipophilic binding pocket within the membrane. Overall, the available evidence positions TRPML1 as a promising target for small-molecule drug discovery and provides a framework for the rational design of next-generation lysosome-directed therapeutics.",

In particular, ferroptosis, an iron cell death mechanism, is a key driver of PD pathogenesis, and its modulation represents a feasible therapeutic target. Here, we designed a neuromelanin-mimetic polydopamine (PDA)-based nanomedicine to attenuate ferroptosis-associated oxidative stress and iron dysregulation in PD by functionalizing PDA nanoparticles with triphenylphosphonium (TPP) for mitochondrial targeting and loading rosmarinic acid (RA), yielding TPRA nanoparticles (TPRA NPs). TPRA NPs combine the antioxidative and iron-chelating attributes of RA with reactive oxygen species (ROS)-responsive release properties. TPRA NPs exhibited efficient RA loading, sustained ROS-triggered release, effective iron chelation, and comprehensive free radical neutralization. In vivo evaluations in Caenorhabditis elegans demonstrated that TPRA NPs were well-tolerated at concentrations up to 64 \u03bcg/mL, with no detectable adverse effects, and enhanced healthspan and stress resistance. TPRA NPs markedly attenuated ferroptosis-associated markers by decreasing excess iron, lipid peroxidation, and ROS while simultaneously restoring glutathione balance, locomotor performance, and modulating ferroptosis-associated genes in worms induced with 1-methyl-4-phenylpyridinium (MPP+), erastin, or iron. Furthermore, these nanoparticles preserved the viability of DA neurons and restored neurobehavioral function and mitochondrial integrity. TPRA NPs reduced \u03b1-synuclein deposition, lengthened lifespan, and activated SKN-1 signaling while upregulating mitophagy-related genes in \u03b1-Syn expressing NL5901 worms, thereby strengthening endogenous defenses. These findings establish targeted, natural polyphenol-loaded biomimetic nanoparticles as a potential approach to mitigate ferroptosis-associated stress in PD.",

However, the precise molecular mechanisms of BPA-induced chronic neuroinflammation remain unknown. In this study, male C57BL/6 mice were administered BPA at different doses for one month, followed by a one-month washout period. We then conducted behavioral tests, oxidative stress assays, and immunohistochemistry to quantify neuronal density and the activation of microglia and astrocytes in the central nervous system. We also carried out RT-qPCR gene expression analysis of the hippocampus for the cGAS-STING-NLRP3 pathway, cytokine assays, and microglial markers to decipher the immune responses in the hippocampus following BPA exposure. BPA induced dose-dependent behavioral deficits, which were most pronounced at 50\u00a0mg/kg. These findings suggest that cGAS-STING signaling acts as a key upstream mediator of BPA-induced hippocampal neuroinflammation and cognitive dysfunction.",

The levels of MNPs are highly correlated with the occurrence of various brain disorders, suggesting the potential central nervous system (CNS) toxicity of MNPs. In this review, we summarize the major circuits by which MNPs may transport into and out of the CNS, including blood-brain barrier crossing, nasal-to-brain routes, and glymphatic system transport. Small-sized MNPs are difficult to eliminate from the brain, which may explain why MNPs may accumulate in the brain. We further discuss the potential neurotoxic effects of MNPs, such as inducing synaptic and neuronal injury, promoting neuroinflammation, dysregulating the neuroendocrine system, and modulating the gut-brain axis. MNP-induced CNS toxicity follows a pattern in which increased susceptibility occurs before direct toxicity. We also review evidence that MNPs, together with environmental and genetic factors, may synergistically contribute to cognitive impairment in Alzheimer's disease, motor dysfunction in Parkinson's disease, and depression- and anxiety-like behaviors. Prenatal exposure to MNPs might induce autism spectrum disorder-related phenotypes in offspring. MNPs could also obstruct cerebral vessels and trigger acute cerebrovascular diseases, as well as promote the entry of viruses such as SARS-CoV-2 into the CNS, thereby increasing the occurrence of neurological symptoms. Finally, this review discusses physical, pharmacological, and plastics substitution interventions designed to regulate MNPs transport in the brain and enhance neuroprotection, thereby reducing CNS toxicity of MNPs.",

CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons. Importantly, CHCHD2 and CHCHD10 promoted autophagy. CHCHD2 reduced protein aggregates in cells and toxic SNCA/\u03b1-synuclein species in mouse striatum. Our study thus revealed mitochondrial proteins CHCHD2 and CHCHD10 as both autophagy substrates and autophagy activators and laid groundwork for therapy targeting patients with neurodegeneration.Abbreviations: AA: amino acid; AD: Alzheimer disease; ALS: amyotrophic lateral sclerosis; ATG5: autophagy related 5; ATG7: autophagy related 7; ATG8: mammalian Atg8-family protein; ATG13: autophagy related 13; bafA1: bafilomycin A1; C1QBP/p32/gC1qR/HABP1: complement component 1, q subcomponent binding protein; CHCHD2/MNRR1/MIX17B: coiled-coil-helix-coiled-coil-helix domain containing 2; CHCHD10/MIX17A: coiled-coil-helix-coiled-coil-helix domain containing 10; CHX: cycloheximide; CMA: chaperone-mediated autophagy; CRISPR: clustered regularly interspaced short palindromic repeats; CQ, chloroquine; DA: dopaminergic; DMSO: dimethyl sulfoxide; EBSS: Earle's balanced salt solution; RB1CC1/FIP200: RB1 inducible coiled-coil 1; FTD: frontotemporal dementia; GABARAP: gamma-aminobutyric acid receptorbassociated protein; GABARAPL1: GABA type A receptor associated protein like 1; GABARAPL2: GABA type A receptor associated protein like 2; hESC: human embryonic stem cells; iPSC: induced pluripotent stem cell; KO: knockout; LAMP1: lysosomal-associated membrane protein 1; LAMP2A: lysosomal-associated membrane protein 2A; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; LIR: LC3-interacting region; PD: Parkinson disease; SQSTM1/p62: sequestosome 1; TARDBP/TDP-43: TAR DNA binding protein; TH: tyrosine hydroxylase; TMR, tetramethylrhodamine; WT: wild type; UB: ubiquitin; ULK1: unc-51 like kinase 1.",

However, its role in mitigating bisphenol A (BPA)-induced dopaminergic dysfunction and cognitive impairment remains insufficiently explored. Many studies have shown that BPA exposure causes neurodegeneration via mechanisms involving dopaminergic system dysfunction, oxidative stress, and neuroinflammation. Therefore, the present study aimed to investigate whether GAS mitigates the effects of BPA-induced cognitive impairment through neuroinflammation in a rat model. Weanling male\u00a0Wistar rats exposed to BPA (50\u00a0\u00b5g/kg b.wt.\u2009\u00d7\u200930\u00a0days, po) were subsequently treated with GAS at two dose levels (30 and 60\u00a0mg/kg b.wt., ip\u2009\u00d7\u20097\u00a0days). After 24\u00a0h, neurobehavioral functions (Barnes maze and Y-maze tests), cresyl violet staining, and ultrastructural analysis were performed, demonstrating significant memory deficits and neuronal degeneration in BPA-exposed rats. In contrast, GAS treatment significantly improved memory impairment and reduced neuronal cell death in the prefrontal cortex (PFC). mRNA, protein, and immunohistochemical expression of inflammatory markers such as tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), (Iba-1), glial fibrillary acidic protein (GFAP), and nuclear factor kappa B-p65 (NF\u03baB-p65) were significantly increased in BPA-treated rats, indicating enhanced glial activation and neuroinflammation, whereas GAS effectively attenuated these alterations. Additionally, dopaminergic markers such as\u00a0tyrosine hydroxylase (TH), dopamine transporter-1/solute carrier family 6 member 3 (DAT-1/SLC6A3), and dopamine receptor D4 (DRD4) were significantly downregulated following BPA exposure and were restored by GAS treatment. Overall, findings suggested that\u00a0GAS exerts protection against BPA-induced neurotoxicity by suppressing NF-\u03baB-mediated neuroinflammatory response and modulating dopaminergic signaling, thereby improving cognitive and neuronal outcomes in the PFC.",
        "42190388": "ID: 42190388\nTitle: Parental Bisphenol S exposure induces oxidative stress and disrupts serotonergic and cholinergic neurotransmission in zebrafish offspring.\nAbstract: Bisphenol S (BPS), a structural analogue of bisphenol A (BPA), is widely used in consumer products and increasingly detected in aquatic environments, raising concerns about its long-term ecological and health impacts. Although short-term developmental neurotoxicity of BPS has been documented, its potential intergenerational effects remain largely unknown. In this study, zebrafish (F0) embryos were exposed to an environmentally relevant concentration of BPS (30\u202f\u00b5g/L) from 4 to 120\u202fh post-fertilization (hpf) and subsequently reared in clean water until adulthood (6 months). Adult fish were then crossed to generate F1 offspring through maternal, paternal, and parental lineages, which were assessed for behavioural and molecular endpoints. Although hatching success, survival, and behaviour remained unaffected across maternal, paternal, and parental lineages, distinct lineage-specific molecular alterations were observed. All lineages exhibited increased reactive oxygen species, lipid peroxidation, and neuronal apoptosis, accompanied by suppression of gpx1a and mn-sod and induction of creb1a, indicating persistent oxidative stress and apoptotic activation. The serotonergic pathway showed marked vulnerability, with downregulation of htr1aa, htr2a, and slc6a4a and elevated serotonin levels, particularly in the parental lineage. Cholinergic signalling was similarly affected, as chata and slc18a3a were upregulated while acetylcholine concentrations increased, suggesting cholinergic hyperactivity. Neurotrophic markers revealed bdnf upregulation and manf downregulation, implying impaired neuronal maintenance and endoplasmic-reticulum stress. Lineage comparisons revealed that the maternal BPS lineage primarily exhibited alterations in serotonergic and cholinergic signalling, whereas the paternal BPS lineage showed stronger oxidative and neurotrophic disruption, and the parental BPS lineage exhibited both, representing the most comprehensive molecular perturbation. These results demonstrate that parental exposure to environmentally relevant BPS concentration induces stable, lineage-specific transcriptional and neurochemical reprogramming without overt phenotypic change. Such latent molecular neurotoxicity highlights the capacity of BPS to silently compromise neurotransmission and stress-response networks across generations, emphasizing the need to include molecular inheritance endpoints in future BPS risk assessments.",

Alarmingly, polystyrene nanoplastics (PS-NPs) have been detected in brain tissues, showing their capability to penetrate the blood-brain barrier (BBB). However, most previous animal studies used high-dose acute exposures, which may not properly reflect the common long-term, low-dose exposure scenarios in real-world. Thus, we conducted a 17-month exposure study in mice using PS-NPs with significantly lower dosage and assessed their behavior and brain damage. Our results demonstrated that prolonged exposure induced oxidative stress in the brain with significantly elevated reactive oxygen species (ROS) and malondialdehyde (MDA) levels, as well as activated immune responses, including microglial activation (Iba1+) and increased release of inflammatory cytokines, indicating a chronic inflammatory state in the brain. In behavioral experiments, only the elevated plus maze (EPM) showed significant differences, however, pathways linked to neurodegenerative diseases like Parkinson disease were notably upregulated. This unfavorable molecular network restructuring may heighten the risk for such disorders. These findings provide critical evidence for the adverse neural effects of long-term, low-dose PS-NPs exposure, thus laying the ground for further more detailed investigation and offering insights for future health interventions and preventive strategies.",
        "42201050": "ID: 42201050\nTitle: Urinary Biomarkers in Parkinson's Disease: A Structured Integrative Review of Pathophysiological Pathways.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by complex and interconnected pathophysiological mechanisms, including mitochondrial dysfunction, oxidative stress, neuroinflammation, lysosomal impairment, and altered neurotransmitter metabolism. Unlike cerebrospinal fluid or blood, urine offers a truly non-invasive source of biomarkers, reflecting systemic metabolic changes and renal protein excretion linked to neurodegeneration. This review aims to critically synthesize current evidence on urinary biomarkers in PD and to organize this heterogeneous literature into pathophysiologically meaningful domains. A comprehensive literature search of human studies investigating urinary biomarkers in PD was performed. Eligible studies were comprehensively analyzed and classified according to dominant biological pathways. To facilitate interpretation, findings were organized into six thematic domains: genetic and protein-based biomarkers; metabolic pathways and mitochondrial dysfunction; oxidative stress and neuroinflammation; gut-brain-axis-related metabolites; hormonal and systemic biomarkers; and emerging exploratory markers. Results were summarized in domain-specific tables and integrated using a conceptual framework. A total of 32 human studies met the inclusion criteria, revealing diverse urinary molecular signatures associated with PD across multiple biological domains. Genetic and protein-based markers, including LRRK2-related proteins, \u03b1-synuclein species, and lysosomal lipids, showed potential for disease stratification. Metabolomic studies consistently identified alterations in acylcarnitines, organic acids, and amino acid metabolism, reflecting mitochondrial dysfunction. Biomarkers related to oxidative stress, immune activation, gut microbiota metabolism, and hormonal regulation further highlighted the systemic nature of PD. However, most individual biomarkers lacked disease specificity and exhibited methodological heterogeneity. Current evidence supports urine as a valuable source of systemic biomarkers reflecting multiple pathophysiological processes in PD. While single urinary markers remain insufficient for clinical application, integrated omics-based approaches-particularly metabolomics and peptidomics/proteomics-hold promise for identifying combinatorial biomarker signatures. Future longitudinal and standardized studies are required to enhance specificity and translational potential for non-invasive diagnosis and disease monitoring in PD.",

However, protein homeostasis efficiency declines with age, leading to the accumulation of aberrant protein structures associated with neurodegenerative diseases such as Parkinson's disease (PD). PD is characterized by the aggregation of alpha-synuclein (\u03b1Syn) into cytoplasmic inclusions. This process is accompanied by elevated phosphorylation at serine 129 (S129). The accumulation of \u03b1Syn into aggregates and their propagation disrupts key proteostasis pathways, including the ubiquitin-proteasome system (UPS) or autophagy, contributing to cellular dysfunction and neuronal death. This study identified the proteasome activator Blm10 and its human ortholog PA200 as modulators of \u03b1Syn degradation and toxicity. The conserved Blm10/PA200 protein plays a key role in regulating proteasome activity and assembly. The \u03b1Syn expression increases Blm10 protein stability through autophagy inhibition, in a manner dependent on \u03b1Syn phosphorylation at S129 in yeast. Overexpression of BLM10 or PA200 reduces \u03b1Syn aggregation and enhances \u03b1Syn turnover via activation of the 20S proteasome in yeast and mammalian cells. Blm10 and PA200-capped 20S proteasomes efficiently degrade both monomeric as well as oligomeric \u03b1Syn in\u00a0vitro. Notably, capped proteasomes retain proteolytic activities in the presence of \u03b1Syn, indicating resistance to \u03b1Syn-induced inhibition, in contrast to 20S or 26S proteasomes. These results reveal a distinct proteasome subtype that bypasses UPS impairment and restores proteolytic capacity under proteotoxic stress. Our findings establish Blm10/PA200 as critical regulators of \u03b1Syn proteostasis and highlight its protective role in maintaining protein homeostasis and cell viability under conditions of \u03b1Syn toxicity.",

This study explored the potential of BPA and NP to drive neuronal injury and ferroptosis linked to oxidative stress, acting through the transient receptor potential melastatin 2 (TRPM2)-poly (ADP-ribose) polymerase-1 (PARP1) signaling axis. Forty-two adult male Wistar rats were allocated into seven groups (control, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA, low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] NP, and low-dose [25\u2009mg/kg]/high-dose [100\u2009mg/kg] BPA\u2009+\u2009NP) and treated orally for 21\u2009days. We employed a combinatorial approach of biochemical assays and immunohistochemistry to evaluate oxidative stress markers, ferroptosis hallmarks (glutathione peroxidase 4 [GPX4], solute carrier family 7 member 11 [SLC7A11], and transferrin receptor [TfRC]), apoptotic mediators (Caspase-3 and Caspase-9), and inflammatory cytokines, as well as the expression of TRPM2 and PARP-1. Results demonstrated that BPA and NP exposure triggered a robust, dose-dependent accumulation of reactive oxygen species (ROS) and lipid peroxidation, concomitant with downregulation of anti-ferroptotic proteins (GPX4 and SLC7A11) and upregulation of TfRC. This toxic insult simultaneously activated apoptotic and inflammatory cascades. Crucially, TRPM2 and PARP-1 were significantly upregulated, implying a potential role for the TRPM2-PARP-1 axis as an upstream modulator of oxidative stress-induced ferroptosis and neuroinflammation. Collectively, these findings provide novel mechanistic insights into phenol-induced neurotoxicity, highlighting the inhibition of the TRPM2-PARP-1 axis as a promising therapeutic strategy to mitigate environmental neurodegeneration in sensory neurons.",

Exposure to BPA can cause toxicity in multiple organs, especially the liver. Trans sodium crocetinate (TSC) is a synthetic salt derived from crocetin extracted from Crocus sativus. TSC exhibits antioxidant, anti-apoptotic, and properties that inhibit autophagy. This study evaluates the effects of TSC on liver toxicity induced by BPA. A total of 42 rats were allocated into seven groups, including those exposed to BPA at a dose of 75 mg/kg, BPA and trans sodium crocetinate (TSC) at doses of 10, 20, and 40 mg/kg, and groups receiving olive oil, distilled water, or TSC (40 mg/kg) alone. The total antioxidant capacity (TAC), lipid peroxidation, and glutathione, as well as serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), and total bilirubin were assessed using colorimetric methods. Reactive oxygen species (ROS) and liver protein expression were quantified using fluorimetric and western blot techniques. TSC, at the dose of 40 mg/kg, reduced the levels of ROS and lipid peroxidation induced by BPA, while remarkably increasing the glutathione content and total antioxidant capacity (TAC) in liver tissue. Moreover, TSC markedly alleviated the BPA-induced increases in caspase-3 protein levels and in the activities of ALT, AST, ALP, and LDH, as well as in serum bilirubin T. Altogether, TSC can be regarded as a supplement to protect against BPA-induced hepatotoxicity due to its potent antioxidant and anti-apoptotic effects.",

A total of 225 mussels were collected from Umluj, Saudi Arabia, a relatively unimpacted coastal area of the Red Sea, and experimentally exposed for 72\u00a0h to spherical PE\u2011MPs (50\u00a0\u03bcm diameter) at nominal concentrations of 5, 10, 20, and 60 particles L-1. Genotoxicity, oxidative status, and cellular integrity were assessed by comet assay, thiobarbituric acid\u2011reactive substances (TBARS), superoxide dismutase (SOD) activity, and lysosomal membrane stability (LMS). At 60 particles L-1, DNA strand breakage increased markedly in hemocytes (13.09%) and gill cells (12.21%) relative to controls (2.14%; p\u2009<\u20090.01). Lipid peroxidation was 1.28 nmol TBARS mg protein-1, and activity of gill SOD was decreased by 16.13% of control. LMS was significantly reduced from 134.4\u00a0min in controls to 53.2\u00a0min in the highest exposure (p\u2009<\u20090.01), suggesting impaired cellular homeostasis. Given the short exposure duration, these results are preliminary. They indicate that acute PE-MP exposure at the tested concentrations is associated with measurable genotoxicity, oxidative stress, and reduced lysosomal stability. Longer-term ecological implications remain to be investigated.",

Variants in the GBA gene, encoding the lysosomal enzyme glucocerebrosidase, are not only responsible for Gaucher disease (GD) but also represent a significant genetic risk factor for PD, contributing to lysosomal dysfunction, oxidative stress and autophagy impairment. Among the key regulators of redox homeostasis, the Nrf2/NOX2 signalling axis has emerged as a pivotal pathway in the modulation of neuroinflammation and neurodegeneration. This study aims to explore the pathogenic link between GBA mutations and PD, focusing on the redox imbalance and the role of Nrf2 signalling in an in\u00a0vivo Gba D409V knock-in (KI) mouse model, compared to wild-type (WT) C57BL/6J controls. Animals 8-weeks old were evaluated over a 3-month period, with tissue and behavioural assessments conducted at 7, 14, 30, 60 and 90\u2009days. Early timepoints (7 and 14\u2009days) did not reveal significant changes in behavioural performance, expression of PD-related markers (TH, DAT, \u03b1-synuclein), or oxidative stress indicators, including Nrf2, NOX2, malondialdehyde (MDA) and nitrate/nitrite levels. However, at 30, 60 and especially 90\u2009days, significant alterations emerged, particularly a disrupted Nrf2/NOX2 balance, accompanied by molecular and biochemical signatures of oxidative stress. These findings suggest a time-dependent progression of oxidative alterations in this GD model and support the role of GBA variants in promoting neurodegenerative processes. Unravelling these mechanisms is essential for the identification of early biomarkers and may offer new therapeutic insights for GBA1-associated PD.",

It is involved in autophagy, vesicular trafficking, mitochondrial dynamics, and immune response. Pathogenic mutations of LRRK2 can significantly interfere with these physiological pathways essential for neuronal homeostasis, inducing degeneration of dopaminergic neurons-a characteristic feature of Parkinson's disease (PD). This review comprehensively summarizes the normal cellular functions of LRRK2 and the potential impact of its dysregulation on various physiological pathways, predisposing individuals to familial and sporadic PD. The mechanistic connections between LRRK2's kinase hyperactivity, disturbances in vesicular trafficking and redox status, systemic and neuronal inflammation, and metabolic disorders will be thoroughly discussed. Dysregulation of vesicular trafficking, mitochondrial redox balance, inflammatory pathways, and metabolism promotes \u03b1-synuclein accumulation and contributes to the degeneration of nigrostriatal dopaminergic neurons, a central pathological feature of PD. Understanding the physiological role of LRRK2 across neuronal and peripheral tissues uncovers its connection with multiple pathways to maintain homeostasis. Its dysfunction disseminates local stresses into broader neurodegenerative changes. LRRK2 is implicated in multiple pathways that control neuronal integrity and neurodegeneration. Therefore, therapeutic targeting of LRRK2 could potentially help in restoring physiological function and management of PD.",

However, the role of redox-sensitive ion channels, such as TRPM2, and potential protective interventions have not been thoroughly explored. This study provides novel mechanistic insight into TRPM2-mediated neuronal damage and highlights the potential of zingerone (ZG) as a natural therapeutic strategy against environmental neurotoxicity. The cells were exposed to BPA (250 \u00b5M) with or without ZG (25 \u00b5M) for 24\u00a0h. We assessed cell viability (CCK-8), oxidative stress parameters (MDA, ROS, GSH, and GSHPx), inflammatory cytokines (IL-1\u03b2, IL-6, and TNF-\u03b1), apoptotic caspases (3, 8, and 9), and TRPM2/PARP-1 expression using ELISA and Western blotting. Exposure to BPA significantly reduced cell viability and triggered oxidative imbalance, inflammation, and apoptosis, as well as upregulation of TRPM2. In contrast, co-treatment with ZG restored antioxidant defences, suppressed cytokine release, inhibited caspase activation, and downregulated PARP-1/TRPM2 signaling. These results suggest that ZG protects against BPA-induced neuronal damage by regulating PARP-1/TRPM2-associated redox signalling pathways and provide further evidence for TRPM2's involvement in environmental neurotoxicity.",

This review analyze the application of gene silencing mediated by small interfering RNAs for \u03b1-synuclein protein and inflammatory factors in the treatment of PD. The use of exosomes-mimetic nanoparticles (EM-NPs) for siRNA delivery will be highlighted in particular. This review highlights recent findings on the molecular mechanisms involved in PD, the development of siRNA drugs, and the potential of EM-NP-mediated siRNA delivery systems for CNS delivery. siRNA provides an excellent approach to silence specific disease-related genes, such as SNCA and inflammatory factors. Nevertheless, its practical application is hampered by low stability, enzymatic degradation, difficulty crossing the BBB, and non-specific activity. EM-NPs combine the advantages of biocompatibility and scalability that natural exosomes possess and synthetic nanoparticles exhibit, respectively. The delivery of siRNA molecules via EM-NPs could be considered an innovative disease-modifying approach toward treating PD patients, involving both pathological \u03b1-synuclein protein and neuroinflammation.",

Cathepsin D (CTSD), a lysosomal hydrolase essential for \u03b1-syn clearance, becomes functionally impaired when its maturation is disrupted, exacerbating proteostatic stress. This study investigated whether ginsenoside Rg1(Rg1) restores CTSD maturation and lysosomal function to mitigate PD pathology. MPTP-induced zebrafish and mouse PD models, as well as MPP+-treated SH-SY5Y cells, animals and cells were treated with Rg1 at different concentrations. Motor behavior, dopaminergic neuron survival, \u03b1-syn clearance, CTSD maturation, lysosomal activity, endoplasmic reticulum (ER) stress, oxidative stress, autophagic flux, and apoptosis were systematically evaluated. Rg1 improved locomotor performance and preserved dopaminergic neurons, promoted \u03b1-syn clearance, and enhanced CTSD maturation in lysosomes. These effects coincided with reduced ER and oxidative stress, normalized autophagic flux, and decreased apoptosis. Rg1 functions as a natural lysosomal enhancer, restoring lysosome-ER homeostasis and counteracting multiple pathogenic pathways in PD. The findings reveal a CTSD-dependent regulatory axis in \u03b1-syn homeostasis and highlight Rg1 as a promising multi-target therapeutic candidate for PD.",

This study evaluated the isolated and interactive toxicity of alone linear low-density polyethylene (LLDPE) (0, 5, 50, 500\u202fmg\u202fL-1) and BaP (0, 3, 12, 21, 30\u202f\u03bcg\u202fL-1) in the mangrove oyster Crassostrea gasar, a key filter-feeding species highly vulnerable to particulate and hydrophobic contaminants. The concentrations of 5\u202fmg/L MPs and all BaP concentrations tested are environmentally relevant. Adult oysters were exposed for 7 days in a full factorial design, and biomarkers (Glutathione S-transferase, Glutathione Peroxidase, Reduced Glutathione, Lipid Peroxidation, DNA damage, Neutral Red Retention Time) were assessed in gills and hemolymph. Alone MPs alone induced oxidative and cytogenotoxic effects, confirming that even uncontaminated plastic particles can disrupt cellular homeostasis. Significant interactive effects between MPs and BaP were observed, particularly influencing oxidative stress and DNA integrity. GPx, GST, and GSH responses were associated with DNA damage at higher exposure levels. BaP increased lipid peroxidation, reducing lysosomal membrane stability, and this impairment was exacerbated under combined exposure. The integrated biomarker response index identified the combination of 30\u202f\u03bcg\u202fL-1 BaP and 500\u202fmg\u202fL-1 MP as the most hazardous scenario. The environmentally relevant MP concentration (5\u202fmg\u202fL-1) also produced significant effects when combined with BaP. These findings demonstrate that MPs modulate BaP toxicity and highlight the importance of assessing co-contaminant interactions in filter-feeding organisms. Although the highest concentration tested (500\u202fmg\u202fL-1) exceeds environmental levels, effects were also observed at environmentally relevant concentrations. The inclusion of elevated concentrations was intended to identify effect thresholds and underlying mechanisms, providing robust data for environmental risk assessment.",

Mutations in the GBA1 gene, encoding the lysosomal enzyme glucocerebrosidase (GCase), are major genetic risk factors for PD. GBA1 deficiency causes lysosomal dysfunction, leading to \u03b1-synuclein (\u03b1-syn) accumulation and PD progression. However, the underlying mechanisms remain unclear. In this study, we identified a novel GBA1-KAT8 regulatory pathway that controls lysosomal activity. GBA1 overexpression enhances lysosomal enzyme expression, regulates histone H4 acetylation at K16 via KAT8, and promotes lysosome-associated gene expression, highlighting an epigenetic mechanism in lysosomal biogenesis. Furthermore, GBA1 upregulated KAT8 expression, increased lysosomal enzyme levels, and decreased PFF-induced \u03b1-syn accumulation both in vitro and in vivo. The involvement of KAT8 as a critical acetyltransferase that modulates nuclear-lysosomal signaling pathways provides a mechanistic explanation for GBA1 deficiency-induced lysosomal dysfunction in association with PD pathology.",

It is imperative to reduce and limit the absorption of this chemical as it can negatively affect vital organs, including brain and heart. There is no direct curative option for BPA-induced toxicity hence, to bridge this gap, this study was conducted to evaluate the prophylactic effects of Bacillus coagulans against BPA-induced neuro- and cardio- toxicities. In silico techniques were utilized to study the toxicophore of BPA, followed by in vitro probiotic studies to select the best strain with the most physiological stability and pharmacokinetic properties. Positive effect of probiotic against cytotoxicity produced by BPA was studied on PC12 and H9c2 cell lines. After model standardization to select suitable dose for BPA induced toxicities, 42 male wistar rats were divided into seven groups for in vivo studies: normal control (Group 1), probiotic (Group 2), BPA alone (Group 3), BPA\u2009+\u2009standard treated (Group 4), BPA\u2009+\u2009probiotic (low dose) (Group 5), BPA\u2009+\u2009probiotic (medium dose) (Group 6), and BPA\u2009+\u2009probiotic (high dose) (Group 7). Morphological parameters, blood pressure, electrocardiogram, inflammatory cytokine level, antioxidant levels, brain and heart biomarkers, and histology were evaluated to investigate the protective effects. The probiotic showed protective effects, reflected by modulation of MDA, BDNF, CK-MB and IL-6 levels, along with improved tissue histology; however, a consistent dose-dependent response was not observed across all evaluated parameters. Thus, the findings suggest that Bacillus coagulans may have prophylactic potential against BPA-induced neuronal and cardiac toxicities.",

Human exposure to nanoplastics through air, food, and water is becoming unavoidable; however, their direct effects on human immune cells remain poorly understood. Due to their small size, NPs can enter the circulation and directly interact with immune cells, yet their cellular effects in humans remain poorly understood. In this study, we investigated the impact of polystyrene NPs on human peripheral blood mononuclear cells (PBMCs) using an integrated approach that combined imaging, mitochondrial stress testing, basophil activation assays, and single-cell RNA sequencing. Confocal microscopy confirmed efficient cytoplasmic internalization of 25-nm NPs. Optical diffraction tomography revealed that even short-term (1\u202fh) exposure induced pronounced biophysical remodeling, including reduced cell volume and dry mass alongside increased intracellular density and refractive index. Seahorse metabolic profiling demonstrated substantial suppression of mitochondrial respiration across major immune subsets, reflected in reduced basal and maximal respiration, ATP-linked oxygen consumption, and spare respiratory capacity. Basophil activation remained unaffected by NP exposure. Single-cell transcriptomics identified a distinct NP-induced \"stress-cell\" population, characterized by upregulation of heat-shock and proteostasis pathways and concomitant downregulation of mitochondrial-encoded transcripts. Together, these data show that NPs rapidly disrupt mitochondrial function and activate proteotoxic stress programs in human immune cells. By situating these mechanisms within the One Health framework (human, animal and the planet health), our findings highlight how environmental nanoplastic pollution may translate into immune dysregulation and inform integrated environmental-public health risk assessments.",

As populations age worldwide, the epidemiological burden of AD is expected to more than double by 2050, surpassing 150\u00a0million affected individuals. While genetic susceptibility, particularly the apolipoprotein E \u03b54 (APOE4) allele, modulates individual risk, most AD cases are late-onset and shaped by complex interactions between genetic background and modifiable environmental exposures. Environmental pollution has emerged as a critical and potentially preventable contributor to this burden. The 2024 Lancet Commission on Dementia Prevention, Intervention, and Care has identified 14 modifiable risk factors, with air pollution explicitly included. Drawing on evidence from human epidemiological cohorts, experimental animal models, and in vitro neuronal/glial systems, the present review aims to synthesize mechanistic evidence linking environmental pollutant classes to AD-relevant neuropathology. The review examines the growing body of evidence linking major categories of environmental pollutants (ambient particulate matter, heavy metals, pesticides, PFAS, and emerging contaminants including microplastics and nanoplastics) to AD risk and pathogenesis. Special attention is given to studies showing that the characteristic neuropathological features of AD may emerge in children and young adults chronically exposed to heavily polluted urban environments, which highlights critical concerns about when and how these changes develop throughout life. Shared mechanistic pathways through which environmental pollutants promote neurodegeneration are discussed, including neuroinflammation, oxidative stress, blood-brain barrier disruption, tau kinase dysregulation, epigenetic reprogramming, and gut-brain axis dysbiosis. The review also examines the amplifying role of biological aging on neurotoxic vulnerability and proposes a comprehensive, multi-level prevention framework addressing individual exposure reduction, clinical risk identification, and population-level policy interventions.",

This study investigates BPA's toxic mechanism on SNHL. ProTox database was performed to analyze the toxicity of BPA. Intersection genes were screened using network toxicology, and causal genes associated with SNHL were identified through Mendelian randomization. The ligand-protein binding activity was validated through molecular docking and dynamic simulation. BPA showed a toxicity classification of Class 4, with toxicological profiles involving the blood-brain barrier, mitochondrial membrane potential, and estrogen receptor alpha. A total of 92 BPA target genes were found to be related to SNHL. These were enriched in potassium ion channel processes and MAPK, PI3K-Akt pathways. Two-sample Mendelian randomization identified 3 causal genes, with small effect sizes: MANBA (odds ratios [OR]\u2005=\u20050.950, P\u2005=\u2005.009), PDE6D (OR\u2005=\u20051.055, P\u2005=\u2005.001), vascular endothelial growth factor A (OR\u2005=\u20051.030, P\u2005=\u2005.022). Molecular docking with BPA revealed minimum binding free energies of -8.1, -6.7, and -6.1 kcal/mol; MANBA-BPA binding was stable in dynamics simulations. BPA can exert toxic effects on SNHL through potassium channel related processes, as well as MAPK and PI3K-Akt signaling pathways. MANBA, PDE6D, and vascular endothelial growth factor A also play key mediating roles in this process.",

Current pharmacological treatments primarily provide symptomatic relief and have a limited impact on disease progression. This article presents a narrative review of emerging gene therapy approaches aimed at modulating \u03b1-syn expression, aggregation, and clearance as potential disease-modifying strategies for PD. Gene-based interventions include viral vector-mediated gene delivery, antisense oligonucleotides, RNA interference, and gene-editing technologies. Preclinical studies and early-phase clinical trials suggest that these approaches may reduce \u03b1-syn burden, improve motor outcomes, and support dopaminergic neuron preservation. Adeno-associated viral and lentiviral vectors have demonstrated promise for targeted central nervous system delivery, although challenges related to dosage optimization, regional specificity, long-term safety, and immune responses remain. Complementary strategies focusing on enhancing molecular chaperone activity and activating autophagy-lysosomal pathways have also shown potential in facilitating \u03b1-syn clearance. Despite encouraging progress, several limitations hinder clinical translation, including off-target effects, immune activation, and the need to preserve physiological \u03b1-syn functions essential for neuronal homeostasis. Future success will depend on precise molecular targeting, optimized delivery platforms, and rigorous safety evaluation through well-designed clinical trials. This narrative review summarizes current advances, key limitations, and future directions in \u03b1-syn-targeted gene therapy, highlighting its potential role in advancing PD treatment beyond symptomatic management toward disease modification.",
        "42262134": "ID: 42262134\nTitle: Alpha-synuclein at the crossroads of host-virus interactions: immunological roles beyond the nervous system.\nAbstract: Alpha-synuclein (\u03b1-syn) is best known as a presynaptic protein that supports synaptic vesicle dynamics and neurotransmission. Conversely, misfolded or aggregated \u03b1-syn represents a hallmark of synucleinopathies, including Parkinson's disease. Beyond the nervous system, \u03b1-syn has been detected in peripheral compartments, including blood cells and selected epithelial tissues, although the robustness and context dependence of expression outside neuronal and erythroid lineages remain under active investigation. Also, it can be released extracellularly through unconventional secretion or cell damage. These observations have reframed \u03b1-syn as an immune-relevant molecule positioned at host-pathogen interfaces, endowed with antimicrobial peptide-like and damage-associated molecular pattern-like properties that enable shaping of both innate and adaptive immunity. Increasing evidence indicates that viral challenge alters \u03b1-syn expression, localization, and conformational states in central and peripheral settings, in part through interferon-dependent programs that couple antiviral immunity with cellular homeostasis. A plethora of RNA viruses, such as influenza virus, flavivirus, enterovirus, and coronavirus, perturb \u03b1-syn abundance, post-translational modifications, trafficking, secretion, and aggregation propensity. These effects converge on shared mechanisms that include altered proteostasis, autophagy-lysosomal dysfunction, oxidative and mitochondrial injury, and inflammatory signaling. Importantly, outcomes are highly context dependent, ranging from cell-intrinsic antiviral restriction to aggregation-prone states that may fuel chronic inflammation and neurodegeneration. Collectively, the evidence discussed herein supports a dual framework in which \u03b1-syn contributes to antiviral defense; yet, under conditions of sustained inflammation or impaired clearance, it may undergo pathological transformation that promotes neuronal damage. Defining when virus-induced \u03b1-syn responses are protective versus pathogenic, and clarifying their relevance to human disease, will be critical for developing strategies that target host-virus interactions, neuroinflammation, and \u03b1-syn proteostasis in infection-associated synucleinopathies.",

Aligned with the 3Rs (Reduction, Replacement, Refinement of animal experiments) and the EU's roadmap to phase out animal testing, zebrafish eleutheroembryos are key in developing New Approach Methodologies (NAMs) as they are non-protected until five days post-fertilization. While bisphenol A is restricted in the EU, the effects of bisphenol E (BPE) on thyroid hormone system (THS) sensitive endpoints and developmental neurotoxicity (DNT) remain unclear. We investigated whether BPE disrupts THS-sensitive endpoints and induces DNT in zebrafish eleutheroembryos. Based on adverse outcome pathways (AOPs): AOP 364 and AOP 157, we assessed eye morphology, inner plexiform layer (IPL), retinal pigmentary layer (RPE), posterior swim bladder inflation and swimming performance, and transcriptional analysis of THS- and DNT-related genes. We hypothesized that BPE would affect THS-sensitive endpoints, such as RPE and posterior swim bladder inflation, impairing swimming performance, and exert DNT effects through THS-mediated mechanisms. BPE impairs RPE without affecting overall eye development. However, transcriptional analysis of THS-related genes did not support a THS-mediated mechanism. BPE exposure also impaired posterior swim bladder inflation, which was identified as the primary contributor to impaired swimming performance. No effects were seen on quantitative brain measurements, leaving the sensitivity of zebrafish eleutheroembryos for brain morphological assessment unclear. Nevertheless, molecular DNT markers were detected, which could indirectly contribute to impaired swimming performance. Overall, our results demonstrate that the zebrafish eleutheroembryo is a valuable NAM model for assessing THS effects and DNT, and that BPE induces DNT and THS effects.",

Numerous other genes involved in lysosomal sphingolipid, glycosphingolipid, and ceramide metabolism have been proposed as contributors to PD, highlighting the need for genetic analyses across these pathways. The aim was to evaluate the contribution of rare variants across lysosomal genes to PD risk. We analyzed rare variants (minor allele frequency\u2009\u22640.01) across 36 lysosomal genes in 8267 individuals with PD and 68,208 controls, including 793 early-onset PD (\u226450\u2009years) cases. Targeted sequencing was performed in four cohorts at McGill University (3456 cases and 2664 controls) and combined with whole-genome sequencing data from the United Kingdom (UK) Biobank (2848 cases, 62,451 controls) and the Accelerating Medicines Partnership-PD cohort (1963 cases, 3093 controls). Associations were tested using Sequence Kernel Association Test-Optimal across variant classes (rare variants, nonsynonymous, loss-of-function, and predicted damaging variants with combined annotation-dependent depletion score >20), followed by meta-analysis across cohorts. Domain-level analyses were performed for variants located within protein domains. False discovery rate (FDR) correction was applied. Meta-analysis identified a significant association between rare variants in ST3GAL3 and Parkinson's disease (Pfdr\u2009=\u20090.04). Domain-based analyses showed enrichment of nonsynonymous variants within the \u03b2-acetyl-hexosaminidase-like domain of HEXA (P\u2009=\u20098.0\u2009\u00d7\u200910-4), although this signal did not survive correction (Pfdr\u2009= 0.154). In early-onset PD, domain-based analyses identified significant associations in NAGLU (Pfdr\u2009= 7.3\u2009\u00d7\u200910-6) and ST3GAL5 (Pfdr\u2009=\u20090.03).

It is also characterized by abnormal inclusion vesicles, termed Lewy bodies (LBs), enriched with \u03b1-synuclein aggregates that may induce inflammation and neurotoxicity. The possibility that factors involved in other neurodegenerative diseases also affect PD-related pathologies, such as \u03b1-synuclein uptake, was examined. The apoe4 allele is a major genetic risk factor for Alzheimer's disease (AD) and has also been suggested to be involved in PD. Here, we examined the effects of APOE isoform expression on \u03b1-synuclein uptake and autophagy in astrocytes expressing the apoe3 or apoe4 alleles. Using multiple autophagy manipulations (EBSS, chloroquine, and rapamycin treatments), we found that \u03b1-synuclein uptake and autophagy readouts differ between APOE3 and APOE4 astrocytes, supporting a functional link between autophagy status and \u03b1-synuclein levels. Astrocytes expressing APOE4 exhibit reduced uptake of \u03b1-synuclein and reduced autophagy. Moreover, \u03b1-synuclein treatment inhibits autophagy mainly in APOE3-expressing cells. Additional experiments showed that the autophagy inhibitor chloroquine reduced \u03b1-synuclein uptake in APOE3 astrocytes but not in APOE4 astrocytes, while\u00a0the autophagy enhancer rapamycin increased \u03b1-synuclein uptake in APOE4-expressing astrocytes. In addition, we found that Toll-like receptor 2 (TLR2) levels are elevated at both the mRNA and protein levels in APOE4-expressing astrocytes, whereas \u03b1-synuclein increased only TLR2 mRNA levels in APOE3-expressing astrocytes. Using the neurotoxin 1-methyl-4-phenylpyridinium (MPP+), we found that it affects cell growth in both APOE3 and APOE4-expressing astrocytes. MPP+ treatment also reduced autophagy which was partially corrected by rapamycin. Taken together, these findings show that in astrocytes, APOE4 impairs \u03b1-synuclein uptake, which was emended by rapamycin and \u03b1-synuclein inhibits autophagy mainly in APOE3. These findings suggest that autophagy-targeting strategies can modulate astrocyte \u03b1-synuclein uptake; however, given the observed reductions in astrocyte cell number following rapamycin treatment, further optimization or examination of alternative autophagy modulators is needed.",

Once thought to be inert, microplastics are now recognized as biologically active agents capable of accumulating in the body and causing toxic effects across organ systems. This review summarizes current evidence on their oxidative and inflammatory effects in the central nervous system (CNS) and the eye. Studies show that microplastics can cross biological barriers such as the blood-brain barrier (BBB) and blood-retinal barrier (BRB), where they are taken up by cells, impair mitochondria, and trigger inflammation. Microplastics have been found in cerebrospinal fluid, brain tissue, and ocular structures, raising concern about their link to neurodegenerative and retinal diseases, including Alzheimer's, Parkinson's, macular degeneration, and other disorders. Mechanistic data indicate activation of NF-\u03baB and TGF-\u03b21 pathways, promotion of protein aggregation, and disruption of neural signaling. In the eye, microplastics have been linked to oxidative stress, corneal thinning, and photoreceptor damage. However, human studies are limited due to challenges in detecting tiny particles and lack of microplastic-free controls. Research is further hindered by inconsistent definitions, particle diversity, and non-physiological exposure models. We highlight the need for standardized methods, multi-omics tools, and long-term studies to better understand exposure impacts. Given the rise in neurological and ocular diseases, clarifying the role of microplastics is essential for effective public health strategies.",

Stabilizing GCase using small-molecule modulators represents a promising therapeutic strategy. In this study, phytochemicals from Xylia xylocarpa (Roxb.) Taub., a medicinal plant with reported neuroprotective potential, were profiled using LC-QTOF-MS and evaluated as GCase stabilizers through an integrated computational approach. LC-MS analysis in positive and negative modes tentatively identified 19 metabolites, of which 13 low-molecular-weight compounds (<500 Da) were selected for molecular docking against human GCase. Docking revealed six compounds with higher predicted binding affinity than the reference activator Pyrrolopyrazine. Pharmacokinetic screening based on Lipinski's rule of five and ADMET predictions identified Senbusine A as a viable lead candidate. It exhibited favorable binding interactions, forming stabilizing contacts within a non-catalytic inter-monomer interface associated with structural modulation of GCase. PASS analysis suggested a high probability of neuroactive properties. Molecular dynamics simulations (200 ns) confirmed stable binding and reduced conformational fluctuations compared to apo and control systems.

In neurons, communication among the endoplasmic reticulum (ER), lysosomes, and mitochondria is essential for cellular homeostasis. Recent studies have identified vacuolar protein sorting 13 homolog C (VPS13C), a lipid transport protein, as a key mediator of ER-lysosome tethering and as an important component of the response to lysosomal stress. Structural analyses show that VPS13 family proteins form elongated lipid transport channels that are proposed to facilitate phospholipid transfer between adjacent membranes. Following lysosomal damage, VPS13C is recruited to ER-lysosome contact interfaces, where it forms tethering bridges that may support membrane repair by enabling high-capacity lipid transfer from the ER to lysosomal membranes. Beyond membrane repair, these contact interfaces may also participate in broader organelle communication networks. ER-lysosome contacts can occur in proximity to ER-mitochondria junctions, potentially forming multi organelle signaling hubs that coordinate lipid redistribution, calcium signaling, and mitochondrial adaptation. These signals may influence downstream responses, including activation of TFEB and TFE3, which regulate lysosomal biogenesis and autophagy. Disruption of this contact site network has emerged as a potential contributor to Parkinson's disease. Loss of VPS13C function is associated with altered lysosomal homeostasis and intersects with pathogenic pathways involving \u03b1-synuclein aggregation, PINK1/Parkin-mediated mitophagy, and LRRK2 signaling. This review presents a framework in which ER-lysosome tethering is considered part of a staged cellular damage response linking membrane repair, metabolic coordination, and transcriptional adaptation.",

Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration.",

Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE have been introduced as alternatives, raising concerns about their potential toxicity. This review examines the effects of BPA and its analogs on ovarian structure and function based on experimental rodent studies. Evidence indicates that BPA exposure leads to histopathological changes, including reduced follicle numbers, increased follicular atresia, and granulosa cell degeneration, along with alterations in reproductive hormones such as estrogen, progesterone, LH, and FSH. At the cellular level, bisphenol exposure is associated with oxidative stress, mitochondrial dysfunction, and impaired antioxidant defenses, which may trigger apoptosis and autophagy in granulosa cells and affect follicular development and oocyte quality. Overall, these findings indicate that bisphenol analogs may not represent safer alternatives.",

Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern.",

The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate. Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for\u00a0GBA1-PD .",

This study systematically investigated the individual and combined effects of MP and PM on intestinal injury using complementary in vivo and in vitro models. In mice, co-exposure to MP and PM induced pronounced oxidative stress, intestinal inflammation, disruption of epithelial barrier integrity, mucin accumulation, activation of endoplasmic reticulum (ER) stress, and dysregulation of autophagy. Consistently, in C2BBe1 intestinal epithelial cells, combined exposure significantly reduced cell viability and exacerbated oxidative stress, ER stress, and autophagic imbalance, as evidenced by increased reactive oxygen species (ROS), elevated BiP and ATF6 expression, and accumulation of p62 and LC3B-II. Moreover, co-exposure promoted intestinal inflammation, barrier dysfunction, and mucin accumulation, demonstrated by increased ICAM-1, IL-1\u03b2, IL-6, and TNF\u03b1 levels, reduced ZO-1 expression, and upregulated MUC2 expression. Strikingly, combined exposure-induced mucin accumulation may provide physical protection and compensate for barrier disruption. Notably, pretreatment with kefir peptides (KPs) markedly attenuated these deleterious effects in vivo and in vitro, supporting their protective potential. KPs pretreatment alleviated cytotoxicity by reducing oxidative and ER stress markers and normalizing autophagy-related protein expression. In addition, KPs decreased ICAM-1 levels, restored epithelial barrier integrity, and limited mucin accumulation in intestinal cells. Collectively, these findings demonstrate that concurrent exposure to MP and PM exacerbates intestinal injury through coordinated activation of oxidative stress, ER stress, and dysregulated autophagy pathways, and identify KPs as a promising preventive strategy for mitigating pollutant-induced intestinal damage.",

Despite growing evidence linking environmental chemicals to neurological disorders, the mechanisms underlying bisphenol A (BPA)-induced cognitive deficits remain poorly understood. Here, we demonstrate that chronic BPA exposure may induce cognitive impairment in male offspring through disruption of the MGBA, specifically via upregulation of the NLRP3 inflammasome/pyroptosis-related markers. Gravid Kunming mice received BPA (0, 2, 20, or 200\u202f\u00b5g/kg body weight/day) in drinking water until weaning; their male offspring were then orally administered identical doses for nine weeks. Behavioral tests revealed significant deficits in short- and long-term memory following high-dose (200\u202f\u00b5g/kg) BPA exposure. Mechanistically, high-dose BPA reduced hippocampal neuron density, compromised ileal barrier integrity, and induced dysbiosis characterized by decreased \u03b1-diversity (Chao1, ACE, Shannon; P\u202f<\u202f0.05) and an elevated Firmicutes/Bacteroidota ratio. LEfSe analysis identified increased abundance of potentially pro-inflammatory genera at 200\u202f\u00b5g/kg. Crucially, high-dose BPA upregulated the expression of NLRP3, ASC, Caspase-1, GSDMD, and IL-18 in both the hippocampus and ileum, alongside elevated serum TNF-\u03b1 and IL-18, indicating systemic inflammation. Correlation analyses further linked specific microbial shifts to pyroptosis markers and cognitive decline. Collectively, our findings establish that chronic BPA exposure may triffer gut dysbiosis and barrier dysfunction, leading to NLRP3 inflammasome activation and pyroptotic cell death in both the gut and brain, ultimately impairing cognition. These results underscore the neurotoxic risk posed by BPA and provide a mechanistic rationale for stricter regulatory controls on its use in food-contact materials.",

Recently, brain-derived EVs have gained significant attention as non-invasive biomarkers for Alzheimer's disease (AD). Here, we identified sub-50nm extracellular nanoparticles in human brain and blood that lack the hallmarks of small EVs, exosomes, exomeres, and supermeres but are enriched for brain-specific markers, hereafter termed small EPs or 'SECmeres'. We discovered that RNAs associated with SECmeres discriminated AD cases from controls with higher significance than small EVs, large EVs showed no differences. Discriminating RNAs were enriched in small EVs (Synaptotagmin, Alpha-synuclein, MAPT) or SECmeres (L1CAM, Syntaxin, Neurogranin), indicating distinct brain-derived signatures. Single-cell RNAseq deconvolution shows small EVs contain RNAs from diverse brain cells, whereas SECmeres enrich brain endothelial transcripts, lining cerebral blood vessels and forming the blood-brain barrier (BBB). These findings challenge the prevailing view that small EVs are the primary carriers of biomarkers. Collectively, our study shows that blood EVPs carry brain-specific information for liquid biopsy, pending validation in larger blinded clinical trials.",

Here, we outline the development of a lipid nanoparticle (LNP) platform for delivering antibodies into cells to selectively inhibit disease-relevant cytosolic targets. This approach efficiently delivers various therapeutic antibodies into multiple cancer cell lines, inhibiting key transcription factors in inflammatory and cancer signaling pathways. We further demonstrate systemic delivery of therapeutic antibodies in disease models, including \u03b1-synuclein-specific antibodies for Parkinson's disease and RelA-specific Immunoglobulins for acute lung injury using targeted LNP formulations. This work establishes a promising method for using LNPs for the delivery of antibody and antibody-derived therapeutics intracellularly to treat numerous proteome targets.",

Wettst. in Parkinson's disease: In Silico and preclinical insights into dopaminergic neuroprotection.\nAbstract: Parkinson's disease (PD) presents a formidable therapeutic challenge rooted not in a singular pathogenic event but in the convergent failure of mitochondrial homeostasis, redox balance, \u03b1-synuclein proteostasis, autophagy-lysosomal integrity, and neuroinflammatory amplification within substantia nigra dopaminergic neurons. Existing dopaminergic pharmacotherapies address symptomatic deficits while leaving the underlying neurodegenerative cascade unchecked, underscoring the need for disease-modifying strategies with multi-target mechanistic reach. This review examines bacoside-A, the principal triterpenoid saponin complex of Bacopa monnieri (L.) Wettst., as a structurally distinctive, polypharmacological neuroprotective scaffold whose biological relevance emerges from convergence with core vulnerability pathways driving dopaminergic degeneration. Integrating in silico, in vitro, and in vivo evidence, we examine how bacoside-A engages molecular targets including \u03b1-synuclein aggregation intermediates, monoamine oxidase-B, LRRK2 kinase, PINK1-Parkin mitophagy regulators, and the redox sensor DJ-1, with computational predictions providing a coherent mechanistic framework for findings observed across MPP\u207a-, rotenone-, and 6-OHDA-based preclinical models, including attenuation of mitochondrial dysfunction, oxidative amplification, and apoptotic signalling, and partial nigrostriatal preservation with motor improvement in vivo. This review reframes bacoside-A as a stress-buffering, network-active modulator most relevant during early, pre-degenerative disease stages. While no clinical trial has yet evaluated bacoside-A in PD, and findings from cognitive or other non-PD indications cannot be extrapolated as efficacy evidence, the convergent mechanistic, computational, and preclinical evidence presented here provides a strong rationale for advancing bacoside-A toward systems pharmacology-guided preclinical and clinical evaluation as an adjunct neuroprotective candidate.",

It is widely detected in the environment and humans due to its extensive use in plastics and epoxy resins for consumer products such as bottles, containers, and tableware. This review synthesizes current evidence on the molecular and cellular mechanisms by which BPA exposure may contribute to neurotoxicity and AD pathogenesis. We discuss how BPA disrupts endocrine signalling, induces oxidative stress, promotes neuroinflammation, and impairs synaptic plasticity, all of which are implicated in the development and progression of AD. The review also examines the impact of BPA on amyloid-beta accumulation, tau pathology, and cognitive decline, integrating findings from animal models, in vitro studies, and epidemiological research. Furthermore, we address the limitations of BPA alternatives and highlight emerging therapeutic and preventive strategies. This study highlights the pathogenic molecular mechanisms involved, offering a foundation for understanding BPA-induced neurodegenerative processes. By bridging the gap between environmental exposure and neuropathology, this article underscores the urgent need for regulatory action and further research to mitigate the neurodegenerative risks associated with BPA in plastics.",

It has been shown that BPA promotes bone fragility through oxidative stress-induced apoptosis and impaired osteoblast differentiation. The identification of sustainable bioactive substances that alleviate BPA-induced bone toxicity is thus of biomedical and environmental significance. Wolffia globosa (WG), the world's smallest flowering aquatic plant, has recently gained attention as a high-protein, antioxidant-rich nutraceutical, yet its impact on BPA-induced osteoblast dysfunction has not been systematically investigated. This study presents a comprehensive assessment of WG ethanolic extract (WGE) in MC3T3-E1 pre-osteoblasts, incorporating thorough phytochemical characterization, acute high-dose and chronic low-dose BPA exposure models, and multi-faceted mechanistic analysis. LC-MS/MS profiling identified luteolin (116.17 \u00b1 0.69 \u00b5g/g), rosmarinic acid (54.80 \u00b1 2.12 \u00b5g/g), and apigenin (48.77 \u00b1 0.61 \u00b5g/g) as the predominant bioactive compounds. WGE exhibited potent antioxidant capacity across DPPH and ABTS radical scavenging assays, complemented by high ORAC and FRAP values, reflecting broad-spectrum antioxidant mechanisms. Treatment with WGE (25 and 50 \u00b5g/mL) resulted in significant alleviation of BPA-induced cytotoxicity, decreased intracellular ROS levels, and inhibited apoptosis. WGE (12.5 \u00b5g/mL) also modulated autophagy-related markers (LC3-II, Beclin-1, and p62), suggesting potential autophagic participation, although flux verification was not conducted. Treatment with WGE (12.5 \u00b5g/mL) also restored BPA-suppressed osteogenesis under chronic exposure, as evidenced by enhanced alkaline phosphatase activity, and increased both mineralization and upregulation of osteogenic genes including runt-related transcription factor2 (Runx2), collagen type I alpha 1 (Colla1), alkaline phosphatase (ALP), and osteocalcin (OCN). These effects were accompanied by partial reactivation of Wnt/\u03b2-catenin signaling. This study is the first to demonstrate that WGE protects osteoblasts from BPA toxicity by concurrently strengthening antioxidant defenses, limiting apoptosis, modulating autophagy-related markers, and supporting \u03b2-catenin-mediated osteogenesis, highlighting WG as a promising sustainable nutraceutical candidate for the prevention of environmental toxin-related bone fragility.",

Polyethylene (PE), widely used in food-contact materials, can carry bisphenol A (BPA), an endocrine disruptor with oxidative and neuroactive properties. Although both MPs and BPA can cross biological barriers, their acute effects on the prefrontal cortex (PFC) remain poorly understood. The aim of the study was to evaluate the acute impact of orally administered free BPA, free MPs, and BPA adsorbed onto PE MPs (PE-BPA) on oxidative stress, inflammation, and gene expression in the PFC of Wistar rats. Animals received a single dose of BPA, PE-BPA, PE alone, or vehicle. Methods: Biochemical and transcriptional analyses were performed to evaluate the antioxidant and inflammatory responses as well as the potential changes in synaptic-related gene expression. Results: BPA-containing treatments produced selective early molecular responses. Catalase (CAT) and glutathione S-transferase (GST) activities were significantly increased in the PE-BPA group, with GST being also elevated in the BPA-alone group, whereas superoxide dismutase (SOD), myeloperoxidase (MPO), and malondialdehyde (MDA) levels did not significantly change. Transcriptional analyses revealed upregulation of the antioxidant genes Nrf2 and CAT in the PE-BPA group. Co-exposure to BPA and MPs also altered synaptic markers, including decreased brain-derived neurotrophic factor (BDNF) and Sert along with increased Nr2A expression, while inflammatory gene expression remained unaffected. Conclusions: These findings indicate that acute co-exposure to BPA and PE microplastics elicits early antioxidant activation and selective synaptic-related transcriptional changes in the PFC, suggesting that MPs may modulate BPA-associated molecular responses in the brain.",

Growing evidence suggests that PKC may contribute to \u03b1-Syn accumulation in kidney cells through multiple converging mechanisms, including direct phosphorylation of \u03b1-Syn, which promotes its aggregation, disruption of the autophagy-lysosome pathway leading to impaired protein clearance, and amplification of oxidative stress and inflammatory responses that enhance \u03b1-Syn toxicity. In a paradigm-shifting discovery, recent findings from Wuhan University indicate that Parkinson's disease (PD) pathology may originate in peripheral organs such as the kidneys rather than the brain. Abnormal \u03b1-Syn aggregates have been identified in renal tissues of affected individuals, and experimental models demonstrate that compromised kidney function facilitates the systemic spread of these toxic proteins to the brain, potentially initiating neurodegeneration. Notably, \u03b1-Syn accumulation has also been observed in patients with chronic kidney disease in the absence of neurological symptoms, suggesting a potential early reservoir function of the kidneys. In this context, aurothioglucose (ATG), a gold-based anti-inflammatory agent, emerges as a promising therapeutic candidate due to its ability to modulate PKC signaling, attenuate inflammation, and restore proteostatic balance. This review highlights a novel kidney-brain axis in PD pathogenesis and proposes PKC-targeted interventions, including ATG, as potential strategies for early disease modification.",

The G2019S mutation in the leucine\u2011rich repeat kinase 2 (LRRK2) gene is the most common genetic cause of familial and sporadic PD. In dopaminergic neurons, increased kinase activity caused by LRRK2\u2011G2019S mutation impairs synaptic vesicle recycling and dopamine storage, increasing cytosolic dopamine, which is prone to oxidation and generates reactive oxygen species. Simultaneously, the mutation alters iron metabolism through Rab misregulation, increasing iron uptake and lysosomal dysfunction, further amplifying oxidative stress and creating a pro\u2011ferroptotic environment. At the same time, dysregulated calcium signaling, driven by the enhanced activity of L\u2011type calcium channels and impaired mitochondrial calcium buffering via the mitochondrial calcium uniporter, enhances mitochondrial dysfunction. This minireview integrates current evidence linking LRRK2\u2011G2019S to these pathological pathways, highlighting this mutation's role in dopamine, iron, and calcium imbalance.

A portion of patients with SPG11 mutations present with parkinsonism features. While spatacsin dysfunction is linked to neurodegeneration, the underlying cellular mechanisms, especially in the midbrain, remain largely unclear. Here, we demonstrate that loss of Spg11 in mice results in neuroinflammation and lipid accumulation in myeloid cells. Bulk RNA sequencing revealed a strong upregulation of microglial genes in the midbrain of Spg11 knockouts, supported by increased CD68 and CLEC7A expression and morphological changes consistent with microglial activation. Spg11 depletion in two in vivo models of synucleinopathy revealed no enhancement of phosphorylated \u03b1-synuclein-positive inclusions or dopaminergic neuron loss; however, the mice did exhibit Spg11-dependent microglial reactivity. Further in vitro studies using primary bone-derived macrophages revealed increased phagocytic capacity and neutral lipid accumulation under basal and stress conditions. These findings support a model where SPG11 is a critical regulator of microglial activation and myeloid lipid metabolism, contributing to neurodegeneration through pathways distinct from \u03b1-synuclein-mediated pathology.",

Currently, there are limited opportunities for intervention. There is a lack of reliable biomarkers to identify patients with PD, which poses a challenge for clinicians. In this review, recent advances in PD biomarker research, including genomic, epigenomic, proteomic, and non-coding RNA, will be highlighted, with particular emphasis on integrating omics for precision medicine. In addition, the current understanding of PD pathogenesis will be covered, including the root cause of familial and sporadic PD, as well as other significant contributing pathogenic events such as the formation of \u03b1-synuclein aggregates, mitochondrial dysfunction, autophagy, oxidative stress, and neuroinflammation. Recent progress in proteomic biomarkers, including cerebrospinal fluid and blood biomarkers such as \u03b1-synuclein, Neurofilament-Light-Chain, and dopamine-associated proteomics, will be reviewed for their utility. Merging evidence on non-coding RNAs, including microRNAs, long non-coding RNAs, circular RNAs, and piRNAs, further supports the notion of non-coding RNAs' regulatory functions in PD pathogenesis and their potential as non-invasive biomarkers. Lastly, strategies that integrate multi-omics data through systems biology, machine learning, and artificial intelligence are presented as viable approaches to support improved patient diagnosis and stratification, as well as the identification of new drug targets for PD. However, challenges related to heterogeneity, reproducibility, and clinical translation continue to limit the implementation of multi-omics biomarkers in PD.

Notably, GBA mutations not only enhance PD susceptibility in the general population but also accelerate disease progression. Nevertheless, the precise molecular mechanisms underlying GBA-associated PD pathogenesis remain elusive. In this study, we demonstrated that the L444P mutation in GBA significantly impairs the enzymatic activity of its encoded protein, glucocerebrosidase (GCase). It caused lysosomal dysfunction and increased \u03b1-synuclein (\u03b1-syn) expression and aggregation induced by \u03b1-syn preformed fibril (PFF). Mechanistically, our data revealed that the L444P GBA mutation increased reactive oxygen species (ROS) levels associated with activation of the p38 MAPK signaling pathway. Importantly, pharmacological inhibition of p38 MAPK pathway can change consistent with altered autophagic degradation and reduce PFF-induced \u03b1-syn aggregation, which is exacerbated by the L444P GBA mutation. These findings suggest that inhibiting p38 signaling provides a mechanistic rationale for targeting this pathway in GBA-associated PD.",

In this study, a borneol-modified carboxymethyl chitosan nanoparticle system (BC/P/HCR NPs) was developed, aiming to codeliver curcumin, rosmarinic acid, and plasmid DNA (pDNA) targeting the SNCA gene for synergistic therapeutic intervention in PD. Borneol is capable of enhancing the permeability of the blood-brain barrier (BBB), while carboxymethyl chitosan contributes to improving the solubility of curcumin and preventing premature drug release. In a C57BL/6 mouse model of PD, BC/P/HCR NPs demonstrated enhanced penetration through the BBB, effectively alleviating motor dysfunction and reducing neuronal damage by downregulating the expression of \u03b1-synuclein, restoring mitochondrial function, and mitigating oxidative stress.

A total of 27 PD patients (19 male, 8 female) and 22 age-matched healthy controls were included. All participants underwent whole-night one-hour polygraphic monitoring, and SS-FR and type of swallowing were analyzed during both wakefulness and sleep stages. Clinical characteristics, disease severity (Hoehn and Yahr staging), and motor symptoms (Unified Parkinson's Disease Rating Scale) were assessed. SS-FR was significantly lower in PD patients compared to controls, both during wakefulness and especially during sleep. In PD patients, SS-FR during wakefulness was positively correlated with Hoehn and Yahr stage and motor symptom scores. The presence of dysphagia was more common in patients with markedly reduced SS-FR, indicating its potential role as a non-invasive marker for swallowing impairment. Salvo swallowing was observed in 4.5% (n\u2009=\u20091) of controls and 40.7% (n\u2009=\u200911) of patients with PD (p\u2009=\u20090.003).

A notable exception is mevidalen, a centrally acting dopamine D1 positive allosteric modulator that paradoxically raises blood pressure. Despite murine knockout models consistently predicting that dopamine receptor deletion produces hypertension, pharmacological antagonism in humans does not reliably raise blood pressure: dopamine D1, D2, and D3 antagonists show largely neutral cardiovascular profiles, while antipsychotic-associated orthostatic hypotension is driven primarily by \u03b11-adrenergic blockade. The cardiovascular response to dopaminergic agents depends on receptor selectivity, intrinsic activity, and baroreflex integrity. The discrepancy between murine-knockout-predicted hypertension and human pharmacological neutrality with antagonists, and the hypertensive effects of dopamine D1 positive allosteric modulators, represent key unresolved questions.",

A Stability Analysis of Parkinson's Disease Clustering.\nAbstract: Although clustering is widely used to explore phenotypic heterogeneity in Parkinson's disease (PD), reported subtype solutions often show limited reproducibility. We investigated whether reducing the number of features or samples in a typical clinical PD dataset more strongly affects clustering stability. We used baseline PD data from the Parkinson's Progression Markers Initiative. We applied K-means, Gaussian mixture models (GMM), and DBSCAN under systematic feature and sample reduction (40 %, 60 %, 80 %, and 100 %). We assessed cluster stability using the Adjusted Rand Index (ARI) relative to feature-matched reference solutions and the pairwise ARI across repeated runs. Sample reduction had the clearest effect on agreement with the reference solution across methods, whereas feature reduction mainly affected run-to-run reproducibility. K-means was the most robust method. Feature reduction lowered reproducibility in GMM, and changes in noise assignment affected DBSCAN. Therefore, reference-solution kstability may depend more on cohort size than features.",

Although studies on animals have suggested neurotoxic effects, evidence from humans is still scarce. This systematic review gathers existing human data to assess the presence, types, detection techniques, and neurological consequences of MNPs in different biological matrices. A comprehensive review was performed on peer-reviewed research concentrating on human studies that report the detection of MNPs in biological tissues and fluids. Four qualifying studies were identified: one clinical observational study, two cadaveric analyses, and one quasi-experimental trial. The data collected encompassed demographics, detection methods, types and concentrations of polymers, biological matrices examined, and neurological biomarkers. MNPs were observed in cerebrospinal fluid (CSF), faeces, urine, olfactory bulbs (OBs), and in brain, liver, and kidney tissues from postmortem cases. The polymers that were reported most frequently were polyethylene (PE) and polypropylene (PP). The detection methods included micro-Fourier transform infrared spectroscopy (\u00b5FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Although the available evidence is limited, emerging findings indicate the possible accumulation of MNPs in the human central nervous system (CNS), particularly in individuals with dementia or compromised blood-brain barrier (BBB) integrity. Relationships were noted between MNP exposure and disruptions in the BBB, inflammatory markers, and alterations in the gut-brain axis. This review consolidates the findings and emphasizes the need for further exploration of human exposure to MNPs and their possible accumulation in neural tissues. Although there is variability in methodologies used in the reviewed articles, PE and PP stand out as the primary polymers of concern. While a direct causal relationship cannot yet be confirmed, the results highlight the necessity for improved detection methods, larger sample sizes, and long-term studies to better understand the impact of MNPs on neuroinflammation and neurodegeneration.",

To compare postoperative complications and reoperation rates between posterior cervical laminectomy and fusion (LF) and laminoplasty (LP) in myelopathy patients with concomitant Parkinson disease (PD). LF and LP are both widely accepted treatments for cervical spondylotic myelopathy (CSM), although the impact of coexisting Parkinson disease on outcomes is unclear. Given the neurodegenerative nature of PD, there is concern for development of kyphosis after laminoplasty due to muscle weakness and lack of coordination. CSM patients with a coexisting diagnosis of PD who underwent primary LF or LP were identified using International Classification of Diseases (ICD) diagnosis codes and current procedural terminology (CPT) codes in the PearlDiver database. Patients were excluded for prior cervical surgery, trauma, tumor, infection, deformity, and anterior or staged procedures. Postoperative complications, including infection, transfusion requirement, kyphosis, and pseudarthrosis, were evaluated and compared between groups along with reoperation rates at 10 years. Statistical significance was assessed by \u03c72, Fisher exact, and t tests as appropriate. A total of 1117 LF and 169 LP patients met inclusion criteria. The median age range was 70-79 years for both groups, and the majority were of moderate risk on Charlson Comorbidity Index. Complication rates were low and similar between groups. No difference in postoperative cervical kyphosis was observed. At 10 years postoperatively, 1.78% of LP patients and 3.85% of LF patients required additional cervical surgery, although this was not statistically significant (P=0.07). Complications and reoperation rates after laminectomy and fusion and laminoplasty in CSM patients with Parkinson disease were relatively low. Reoperation rates were similar between groups with a trend towards lower rates in laminoplasty, indicating that neurodegenerative disorders such as Parkinson disease do not always necessitate fusion.

Their capacity to adsorb, transport, and release contaminants has raised growing concern over mixture toxicity under realistic exposure scenarios. This review systematically examines the mechanistic basis of MNPs-mediated combined toxicity and evaluates the emerging role of network toxicology as a systems-based tool for hazard assessment. MNPs alter the bioavailability, environmental fate, tissue distribution, and intracellular delivery of associated pollutants through hydrophobic, electrostatic, and other intermolecular interactions. Carrier-mediated uptake, particularly the \"Trojan horse\"\u00a0effect, appears to be a major driver of non-additive toxicity in co-exposure systems. We then outline the core workflow of network toxicology, encompassing target identification, network construction, pathway enrichment, and experimental validation, and discuss its application in decoding mixture toxicity. Oxidative stress, inflammatory signaling, metabolic disturbance, barrier dysfunction, and programmed cell death emerge as conserved and interconnected pathways underlying synergistic multi-organ injury. These findings indicate that toxicity in complex exposure systems is governed not only by the intrinsic properties of particles or chemicals, but also by their dynamic physicochemical and biological interactions. We further assess current advances and limitations in network toxicology and propose a next-generation risk assessment (NGRA)-oriented framework to support mechanism-based risk assessment and regulatory decision-making. Although current evidence is dominated by binary, high-dose laboratory studies, network toxicology offers strong potential as a new approach methodology (NAM) for predictive evaluation of environmentally relevant mixtures. Future priorities include standardized multi-omics integration, dose-time-response modeling, human-relevant validation, and regulatory translation.",

However, the precise impact of STN-DBS on LID remains unclear. Here, we investigated the functional roles of two distinct neuronal populations within the STN in regulating LID. In a mouse model of LID, STN neurons projecting to the entopeduncular nucleus (EP) exhibited a U-shaped activation pattern, whereas those projecting to the tegmental reticular nucleus (RtTg) displayed a predominantly inhibitory response. Activation of EP-projecting STN neurons alleviated dyskinesia but worsened hypokinesia in the parkinsonian state. Activation of RtTg-projecting STN neurons alone did not induce hyperkinetic characteristics, except when combined with levodopa. These findings reveal two anatomically and functionally distinct populations of STN neurons involved in LID regulation, offering insights into the circuitry underlying STN-DBS.",

This study investigates the survival of the extensively drug-resistant Acinetobacter baumannii in the presence of selected priority substances including benzene derivatives (trichlorobenzene, pentachlorobenzene, and hexachlorobenzene), trifluralin, and primary polyethylene microplastics. The results indicate that the amount of adsorbed priority substances on microplastics from a mixture solution is slightly lower than the adsorption from individual solutions. Furthermore, GC/MS analysis shows that other chemicals used in plastic manufacturing can be released from microplastics into the environment over time and should be taken into account when assessing the environmental impact of microplastics. The proliferation of the environmental Sava 4 A. baumannii strain was not affected by the presence of benzene derivatives and microplastic particles at concentrations of up to 10 g/L in the water medium, and microscopy confirmed that it can colonise and form a biofilm on microplastic particles with adsorbed benzene derivatives, which demonstrates that microplastics have the potential to spread pollutants and potentially harmful bacteria over long distances and introduce them into various aquatic environments.

However, the co-occurrence of Cd contamination and microplastics (MPs) in soils presents unprecedented challenges for remediation strategies. Using metabolomic analysis, our study first investigated the phytoremediation efficacy of S. canadensis for Cd-contaminated soil under the influences of MPs types (polyethylene terephthalate, PET; polylactic acid, PLA; polyester, PES) and dosages (0, 0.2%, and 2%; w w-1), and biochar (BC) amendment (0 and 1%; w w-1). Results revealed complex polymer- and dose-dependent effects on Cd dynamics, where PES enhanced Cd immobilization, while 0.2% PET/PLA paradoxically increased root Cd accumulation by 5.6%-13.8% despite reducing soil Cd extractability. MPs exposure induced comprehensive physiological perturbations in S. canadensis, including biomass allocation, chlorophyll degradation, micronutrient homeostasis, and profound metabolic reprogramming characterized by the upregulation of allelopathic metabolites. BC amendment effectively immobilized Cd, mitigated oxidative stress, and restored nutrient cycling by enhancing enzyme activities. Crucially, BC decreased the relative abundances of key allelochemicals by 65.3% \u00b1 14.2% through energy metabolic restructuring, while maintaining high phytoremediation efficiency. Significant triple interactions (MPs type \u00d7 MPs dose \u00d7 BC) underscored context-dependency of remediation outcomes, with biodegradable PLA exhibiting distinct ecological implications. These findings demonstrate that integrating BC amendment with S. canadensis phytoremediation offers a sustainable strategy for managing MPs-Cd co-contaminated soils within the framework of ecological security.",

Here, we conducted a full-growth-cycle pot experiment using Epimedium as a model plant, covering seedling (S1), vegetative (S2), and maturity (S3) stages. Polyethylene (PE) and polylactic acid (PLA) were applied at 0.01-0.15% (w/w) combined with Cd at 2\u202fmg/kg. Using 16S rRNA sequencing, PICRUSt2, and structural equation modeling, we assessed soil C/N pools, enzyme activities, bacterial communities, and functional genes. Pollution effects exhibited clear growth-stage-dependent thresholds. The strongest disturbance to C/N pools occurred at S2, with partial recovery at S3. PLA-Cd induced significantly stronger disturbances than PE-Cd, driven by fundamentally different pathways: PE-Cd effects are primarily associated with physicochemical pathways (direct enzyme inhibition), whereas PLA-Cd effects are strongly correlated with microbial community restructuring. Under PLA-Cd, keystone taxa shifted from functional genera (Sphingomonas, Flavisolibacter) to stress-tolerant Acidobacterium, and bacterial co-occurrence network modularity collapsed from 0.362 to 0.227. Predicted abundances of C-fixation, N-fixation, and nitrification genes decreased by 44.9-64.0%, forming a metabolic pattern of suppressed N input and weakened C retention. These findings propose the \"growth stage dependent response pattern\" and a \"differentiated mechanism of synergistic toxicity\", elucidating how degradable vs. non-degradable MPs exert divergent toxic effects. This challenges the common assumption that biodegradable plastics are environmentally friendly under heavy metal co-contamination.",

Methodologically, we design a hydroponic experiment: eleven MP-composition schemes were constructed using polystyrene, polyethylene, and polypropylene (CK sequence), and Eichhornia crassipes was cultivated under these exposures. The comparison sequences included treatments with PFOA and GenX (OA and GX sequences). High-throughput sequencing of 16S rRNA and ITS genes was performed to profile rhizosphere bacterial and fungal communities. Root performance was evaluated using integrative indicators that reflect rhizosphere health and nutrient removal efficiency. The results showed that MP composition shifted bacterial and fungal phylum-compositions without altering the dominant taxa-Proteobacteria (21.77\u223c67.41%) and Bacteroidota (9.43\u223c39.60%) for bacteria and Rozellomycota (11.36\u223c82.81%) and Ascomycota (9.17\u223c48.38%) for fungi. MP diversity significantly influenced bacterial \u03b1-diversity in the OA sequence (k\u202f=\u202f0.171\u223c0.472) and fungal \u03b1-diversity in the CK sequence (k\u202f=\u202f-0.458\u223c0.087). \u03b2-diversity analysis revealed distinct bacterial and fungal response patterns to MP variation across sequences. In the GX sequence, the bacterial assembly was predominantly shaped by homogeneous selection with 50.09% contribution. MP composition also modulated bacterial-fungal co-occurrence networks, with fungal participation notably weakened under PFAS exposure. Under PFOA co-contamination, MP type acted as a module hub in the microbial network. Partial least squares path modeling (PLS-PM) showed that MP composition primarily regulated root performance via hydrochemistry, with bacterial-fungal interactions significantly affecting root performance only in the presence of PFOA (PC=-0.194). This study enhances the understanding of microbial interactions in nutrient removal and root tolerance of floating macrophytes exposed to combined MP and PFAS pollution. It also provides an exploration on utilization of floating macrophyte-based remediation, identifying MP composition as a potential factor.",

Six of the lakes are under protection. Results indicate a diverse array of fiber types with dominant synthetic polymers: polypropylene (PP) and polyethylene terephthalate (PET), as well as numerous organic materials, including cellulose-based fibers (rayon). We found a positive relationship between the amount of microplastic fibers in surface water and the anthropopressure index (IA) calculated for each of the studied lakes. Fiber levels differed significantly between lakes located in protected (33 - 370 items per m3) and urban areas (285 - 845 items per m3). Results indicate that the isolation in protected areas does not shield lakes from airborne microfiber pollution. For five of the lakes investigated results are compared with a previously published study pointing to notable differences in microplastic concentrations detected near shore and in the central part of the lake. Methods of assessing anthropopressure are contrasted and differences in sampling approach are evaluated. Monitoring the abundance and characteristics of microplastics is required to understand their source and patterns of distribution, both of which can be affected by the level of anthropopressure.",

To address this issue, a porous carbon with both high adsorption capacity and efficient electron transfer (or sp2 C content) is first required, but both are mutually limited. Herein, a series of porous carbons (TPS34C-Y) was effectively prepared using a simple process that involved varying the gas atmosphere (i.e., N2, CO2, air, and steam) during the activation of the pine sawdust (PS)/triphenylphosphine oxide (TO) blends. Notably, the porous carbon fabricated at the air atmosphere and 800\u202f\u00b0C temperature (i.e., TPS34C-air) achieved the highest specific surface area (2054.09\u202fm2/g). Not only that, the adsorption capacity of bisphenol A (BPA) by TPS34C-air reached 623.23\u202fmg/g within 60\u202fmin. After coupling with PDS, the removal capacity of BPA increased to \u223c900.00\u202fmg/g, with the oxidation (i.e., degradation) removal capacity reaching \u223c261.10\u202fmg/g. Besides, sp3 C was identified as an adsorption site in a range by correlating the BPA adsorption capacity with texture properties, functional group content, sp3 C, and sp2 C. Similarly, CO can be the primary degradation site in a range, as indicated by correlations between BPA degradation capacity and sp2 C, sp3 C, sp2 C/sp3 C, CO, and CO/C-OH. Encouragingly, the TPS34C-air/PDS system was dominated by the electron transfer pathway (ETP). The present work offers considerable data for identifying adsorption and surface degradation sites in the porous carbon/PDS decontamination system.",

However, the differential impacts of MPs types and related leachates remain poorly understood, particularly for nitrogen-containing MPs. This study compared the variational responses in sediment carbon and nitrogen transformation to 1% aged MPs (AMPs), leachates (LMPs), washed aged MPs particles (WMPs) derived from nitrogen-containing polyamide (PA) and non-nitrogen-containing polylactic acid (PLA) under natural exposure and freeze-thaw cycles (FTCs). The results showed that the Carbon Pool Management Index (CPMI) in PLA groups was always higher than corresponding PA groups, indicating better sediment quality in the PLA groups. Under natural exposure, LPA and LPLA respectively increased CPMI by 3.4% and 93.6% due to containing biologically available organic matter. FTCs increased CPMI by 34.1% in control groups, whereas only CMPI in AMPs was higher than control groups. Besides, the PLA group reduced the nitrogen mineralization rate by possibly inhibiting the macromolecular organic matter decomposition, and might have reduced the narG/H/I and nirB/D genes, thereby indirectly maintaining the nitrification rate. While the PA group increased the nitrogen mineralization rate by possibly inhibiting the amoA/B/C genes to reduce nitrification rate and enriching ureolytic microorganisms. FTCs mitigated these disparities by intensifying microbial interactions. PLS-SEM suggested that APLA was most strongly associated with carbon and nitrogen transformation within the PLA treatments, whereas the apparent effect of APA was jointly shaped by the opposite associations of WPA and LPA. These findings provide new insights into the complex ecological effects of MPs and their leachates on sediment carbon and nitrogen transformations.",

This study assessed microplastic abundance, polymer composition, ecological risk, and human dietary exposure in commercially important finfish and crustacean species from the Escravos Estuary, Nigeria, using stereomicroscopy, FTIR identification, toxicity-weighted indices, and ingestion-based exposure modelling. Microplastics were detected in all taxa, with a mean abundance of 4.30 \u00b1 0.76 particles g-1. Surface water averaged 20.5 \u00b1 0.7 particles L-1 (n = 2 duplicate samples), and polymer and shape profiles broadly co-occurred between water and biota. Filaments (35%) and fibres (24%) dominated, while transparent and blue particles were most common, suggesting inputs from wastewater, fishing gear, and packaging materials, with possible pigment bleaching under tropical solar exposure. Detected polymers included polyvinyl alcohol, polyacrylamides, chlorosulfonated polyethylene, polystyrene, polymethyl methacrylate, and polyamides. Toxicity-weighted indices were calculated only for polymers with published hazard scores. The mean polymer ecological risk index for water indicated Class IV (7.4 \u00d7 103), and assemblage-level BALI exceeded one. Plastic Estimated Daily Intake values, derived from gastrointestinal concentrations as conservative upper-bound estimates, ranged from 1.35-2.24 particles kg-1 bw day-1 for adults and 6.31-13.59 particles kg-1 bw day-1 for children, reflecting gastrointestinal rather than edible-tissue exposure. Toxicity-weighted risk was more strongly associated with polymer hazard than particle abundance.

In PD, apraxic deficits were generally milder but shared overlapping features with CBS. Direct comparative studies between PD and CBS remain scarce. PSP was characterized by less frequent and predominantly sequence-related impairments, whereas findings in MSA were heterogeneous and less pronounced.

Here, we identify microbiome-derived vitamin B6 (VB6) and its biosynthesis gene as key regulators of host dopaminergic homeostasis. Metagenomic analysis of fecal samples from Parkinson's disease (PD) patients revealed enrichment of biosynthetic pathways for pyridoxal-5'-phosphate (PLP), the active form of VB6, and tyrosine decarboxylase genes. Using E. coli-C. elegans symbiotic models, we demonstrate that the bacterial pdxJ gene, encoding a key enzyme in de novo VB6 synthesis, is essential in regulating host dopaminergic homeostasis. Colonization with pdxJ-deficient bacteria led to reduced host VB6 and dopamine levels, reduced dopaminergic enzyme activity, and altered motor behavior, which were all rescued by VB6 supplementation. In PD-relevant C. elegans models, bacterial PLP biosynthesis modulated \u03b1-synuclein aggregation and behavioral deficits associated with human LRRK2 mutations. In mice, colonization with pdxJ-deficient bacteria reduced serum VB6 levels, decreased tyrosine hydroxylase staining in the substantia nigra, and impaired motor coordination, which were rescued by VB6 supplementation. Overall, our results define a bacterial pdxJ-PLP-dopamine axis that links gut microbial metabolism to host dopaminergic phenotypes and suggest bacterial VB6 biosynthesis as a potential modifier of PD risk and a context-dependent therapeutic target.",

Freezing of gait is a significant mobility impairment with limited effectiveness to L-DOPA in advancing disease implying a role for other neurotransmitters, such as GABA. Imaging studies using [11C]-flumazenil PET and magnetic resonance imaging (MRI) were conducted in 33 patients with Parkinson's disease (9F/24M; age 68.34\u2009\u00b1\u20096.38, disease duration 8.03\u2009\u00b1\u20094.73, motor Movement Disorders Society-revised Unified Parkinson's Disease Rating Scale (MDS-UPDRS) scores 44.01\u2009\u00b1\u200914.85). Patients were classified into two groups: \"freezers\" (n\u2009=\u20098) and \"nonfreezers\" (n\u2009=\u200925), based on the MDS-UPDRS Part III off state examination. Whole brain voxel-based t-tests group comparisons were performed using SPM12. Reduced GABAA binding was observed in the cerebellum vermis, esp. vermis lobule VI, left posterior cingulum, posterior parahippocampal gyrus/fimbriae, medial occipital-temporal gyrus and the right gyrus rectus, right anterior cingulum, and adjacent right superior frontal gyrus that demonstrated significantly reduced GABAA receptor availability in the individuals with freezing as compared to those without. In addition, reductions were also seen in the left posterior putamen and pallidum. Findings may augur a role for GABAA inverse agonists for novel investigation of FOG treatment in Parkinson's disease.",

However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes.",

Despite its proven efficacy, women are less likely to receive DBS. This study examined sex differences across the multistage clinical pathway to identify stage-specific factors contributing to disparities in utilization.DesignRetrospective cohort study using longitudinal clinical data from a single, high-volume neurological care center.MethodsData were drawn from 4,308 patients with PD treated between 2012 and 2024. Progression through the DBS pathway was modeled as four conditional stages: (S1) referral, (S2) multidisciplinary evaluation among those referred, (S3) recommendation among those evaluated, and (S4) DBS surgery among those recommended. Stage-specific Firth penalized logistic regression models were used to estimate sex differences while adjusting for demographic and clinical characteristics, including age, race, comorbidities, marital status, levodopa use, and tremor status. Sex-by-predictor interactions were assessed to identify differential effects across stages.ResultsAmong the cohort (2,866 males, 1,442 females), 186 (4.3%) received a referral for evaluation; 180 (97%) received an evaluation; and 159 (88%) received DBS. Adjusting only for sex, compared to males, females were less likely to be referred (OR=0.97, CI=0.71, 1.32), evaluated given referral (OR=0.88, CI=0.1, 5.17), and receive DBS given recommendation (OR=0.61, CI=0.17, 2.38), but more likely to receive a recommendation after evaluation (OR = 1.55, CI = 0.59-4.70). Sex-Predictors odds ratios differed [male- S1: age (OR=0.95, CI=0.93, 0.97), comorbidities (OR=1.19, CI=1.00, 1.41); S2: comorbidities (OR=0.51, CI=0.20, 0.87); S3: age (OR=0.91, CI=0.84, 0.97), non-white (OR=0.29, CI=0.09, 0.88), comorbidities (OR=1.90, CI=1.09, 3.73); S4: non-white (OR=0.15, CI=0.02, 0.91); [females- S1: unmarried (OR=0.71, CI=0.38, 0.92); S2: levodopa (OR=1.24, CI=1.06, 1.90); S3: non-white (OR=0.01, CI=0.00, 0.31); S4: tremors (OR=1.55, CI=1.04, 1.87)].ConclusionStage-specific regression showed that differential characteristics were associated with sex disparities in DBS utilization, highlighting potential targets for equity interventions. Parkinson\u2019s disease (PD) is a condition that affects movement and can make everyday activities difficult. For some people, a treatment called deep brain stimulation (DBS) can greatly improve symptoms when medications no longer provide symptom relief. DBS is a type of brain surgery that helps control movement problems such as tremors and stiffness. Even though DBS is effective, women are less likely than men to undergo this treatment. This study examined why sex differences DBS receipt occur by analyzing data from over 4,000 patients with PD who received care at a specialized neurological center. Following patients through four key steps: being referred for DBS, completing a detailed evaluation, being recommended for surgery, and ultimately receiving the procedure. This analysis showed that differences between men and women occured at multiple points along this pathway. For example, women were less likely to be referred for evaluation, and social factors such as marital status appeared to play a role. At later stages, clinical factors such as medication use and symptom type influenced whether patients moved forward with surgery, and these factors affected men and women differently. Overall, these findings suggest that unequal access to DBS is not caused by a single issue but instead resulted from a combination of social, clinical, and healthcare system factors. Understanding where these differences occur can help doctors and health systems design targeted strategies to ensure that all patients who could benefit from DBS have an equal opportunity to receive it.",

Increasing evidence suggests that PD is not merely a neurodegenerative disease confined to the central nervous system (CNS) but also involves significant systemic metabolic disturbances and peripheral tissue dysfunction, indicating a systemic pathological character. In recent years, epigenetic modifications have gradually become an important perspective for understanding the inflammatory progression of PD. Lactate is no longer simply considered the end product of glycolysis, but can regulate gene transcription and protein function through protein lactylation. This paper systematically proposes that lactylation is a key molecular bridge between neuroinflammation and sarcopenia in PD. We searched literature from the PubMed database from 2010 to 2026, screened qualified English articles, and integrated the latest research advances in neuroimmunology, skeletal muscle biology, and metabolic epigenetics. In PD, microglia epigenetic modifications and metabolic reprogramming lead to lactate accumulation, which may drive a persistent neuroinflammatory response through lactate modification. Simultaneously, chronic inflammation and metabolic abnormalities can propagate along the brain-muscle axis, promoting skeletal muscle protein metabolic imbalance and accelerating the development of sarcopenia. Based on this, this paper systematically proposes that lactylation is a key molecular bridge between neuroinflammation and sarcopenia in PD. Combining the latest research advances in neuroimmunology, skeletal muscle biology, and metabolic epigenetics, this paper elucidates the potential mechanisms by which abnormal lactate metabolism and lactylation play a role in altered glial cell inflammatory phenotypes and skeletal muscle homeostasis imbalances. Furthermore, in conjunction with exercise intervention studies, this paper explores how lactylation, as a key regulatory molecule, can achieve bidirectional improvement in CNS inflammation and peripheral muscle function, providing a new theoretical basis for systemic intervention strategies for PD.",
        "42400730": "ID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.",

This study introduces FMIND (fuzzy microplastic inference for detection risk), an IoT-enabled fuzzy inference framework for rapid and low-cost microplastic contamination risk assessment. Bottled water stored in PET and stainless-steel containers under sunlight, shade, and freezer conditions was evaluated using IoT sensors measuring temperature, turbidity, and total dissolved solids (TDS) before and after 30\u00a0days of storage. Statistical analysis revealed strong correlations between sensor variations and contamination-related physicochemical indicators, including turbidity (r\u2009=\u20090.861), TDS (r\u2009=\u20090.793), and temperature (r\u2009=\u20090.565) (p\u2009<\u20090.001). The FMIND fuzzy model applied 12 Sugeno rules to generate a contamination risk score (0-100), while the HFIRM-GT enhanced configuration improved classification consistency within the experimental dataset, achieving an F1 score of 0.91. Laboratory validation using FTIR spectroscopy, SEM imaging, and EDAX elemental analysis on selected high-risk samples supported the presence of polymer-associated microplastic fragments in sunlight-exposed PET bottles. The proposed framework does not directly quantify microplastics through IoT sensors; instead, it estimates contamination risk using indirect physicochemical indicators supported by laboratory validation. FMIND integrates IoT sensing, fuzzy reasoning, and chemical validation into a unified and interpretable framework for periodic bottled water contamination risk assessment. The reported predictive performance reflects evaluation within a limited experimental dataset and should be interpreted as preliminary proof-of-concept validation rather than generalized field-scale performance. The system provides a scalable and cost-effective approach that supports Sustainable Development Goal 3 (Good Health and Well-Being), Sustainable Development Goal 6 (Clean Water and Sanitation), and Sustainable Development Goal 12 (Responsible Consumption and Production).",

In this study, we quantified anthropogenic microparticles (AMPs) ingestion and evaluated its relationship with total mercury concentrations (THg; liver\u2009+\u2009muscle) in 23 blue sharks (Prionace glauca) from the northern Tropical Eastern Pacific (TEP), a key corridor for global fisheries and debris transport associated with the North Pacific Garbage Patch. All individuals contained AMPs (mean\u2009\u00b1\u2009SD\u2009=\u200932\u2009\u00b1\u200937 particles per digestive tract). Most particles were\u2009<\u20095\u00a0mm, with fibers as the dominant shape (76%). Among synthetic polymers, polyethylene (PE) and polyethylene terephthalate (PET) were the most abundant. Microplastics (MPs) showed a mean abundance of 12\u2009\u00b1\u200911 particles per digestive tract, whereas more than 60% of FTIR-confirmed particles corresponded to non-plastic anthropogenic microparticles (NPAMPs), mainly cotton, rayon, and cellulose, with a mean abundance of 22\u2009\u00b1\u200927 particles per digestive tract. Generalized additive models (GAMs) identified NPAMP abundance as the strongest predictor of THg concentrations (mean\u2009\u00b1\u2009SD\u2009=\u20091.08\u2009\u00b1\u20090.43\u00a0mg\u00a0kg\u207b1), revealing a significant non-linear relationship with higher Hg levels during the hot-rainy season. These findings suggest that NPAMPs may represent, together with diet, an additional pathway associated with Hg exposure in P. glauca. Risk indices (PLI, MPDI, and PHI) indicated low-to-moderate contamination levels; however, more than half of the individuals exceeded polymer hazard thresholds (PHI\u2009>\u20091000). Given the observational design, limited sample size, and the fact that seasons were sampled in different years, the NPAMP-THg relationship should be interpreted as co-occurrence rather than direct evidence of contaminant transfer. Furthermore, because particles were quantified only in non-edible tissues, these findings cannot be directly extrapolated to seafood safety risk. Nevertheless, NPAMPs emerge as a previously under-recognized component of contaminant exposure in pelagic predators and should be incorporated into future marine monitoring frameworks.",

Their connection to micro-nanoplastics (MNPs) emitted as particulate matter from incineration of plastics remains poorly explored. In this study, we detected 65 Polycyclic Aromatic Hydrocarbon (PAH), oxygenated (OPAH) and nitrated (NPAH) PAC species in MNPs emitted during the incineration of three widely used plastic materials, high-density polyethylene (HDPE), polypropylene (PP) and polyvinyl chloride (PVC). MNPs were generated using the incineration exposure generation system (INEXS) and their PAC profile was offline analyzed using gas chromatography-mass spectrometry. Notably, one of the most abundant species in all three plastics was Benzanthrone, an OPAH previously associated with traffic and biomass burning emissions. MNPs emitted by PVC incineration contained emerging highly toxic PAC species such as benzo(c)fluorene, dibenzopyrenes, and 6-nitrochrysene. Our findings highlight the importance of monitoring beyond the legacy 16 EPA members which accounted only by 12%, 47%, and 41% of the associated carcinogenic potency (expressed as BaPeq), for PVC, PP and HDPE respectively. These results raise concerns for potential health implications and underscore the urgent need for further research on this new environmental challenge, MNP pollution and its association with toxic persistent pollutants.",

However, their ecological hazards following environmental fragmentation and aging remain insufficiently understood. In particular, how ultraviolet (UV) weathering alters particle-associated and chemically mediated toxicity of biodegradable mulch films microplastics is unclear. Here, we investigated the chronic effects (16 days) of pristine and UV-weathered mulch film microplastics (PMF and UMF, respectively) and their corresponding methanol extracts (EXP and EXU, respectively) on Daphnia magna. By integrating life-history traits, biochemical energy reserves, and transcriptional responses, we disentangled particle and extract exposure. Particle exposure was associated with mortality and broader life-history impairment in D. magna, whereas extract exposure primarily affected somatic growth and reproduction without affecting survival. UV-weathering reduced particle size and increased internal particle burden; however, UMF exposure was associated with comparatively reduced organism-level impairment relative to PMF. Under extract exposure, organism-level responses were broadly comparable between EXP and EXU, whereas EXU exhibited comparatively stronger transcriptional responses related to mitochondrial and carbohydrate metabolism-associated genes. Overall, the effects of UV-weathering were endpoint-dependent rather than reflecting a uniform increase or decrease in toxicity. Instead, UV-weathering modified biological responses differently between particle and extract exposure conditions. These findings highlight the importance of exposure-specific assessment when evaluating the environmental hazards of biodegradable microplastics.",

Despite advances in wastewater treatment plants (WWTPs), the removal of ECs remains limited due to compound-specific behaviour, whereby contaminants undergo adsorption onto sludge solids, partial transformation into intermediates, and phase transfer to biosolids or colloids. The coexistence of ECs in complex wastewater matrices induces competitive interactions, matrix effects, and non-linear transformation pathways, reducing predictability and treatment efficiency. In this context, this review aims to provide a mechanistic understanding of EC fate and transformation in WWTPs, linking molecular properties to variability in removal across treatment configurations. It examines transformation pathways across treatment stages, integrates advances in detection with physicochemical and biological mechanisms, and highlights limitations of conventional WWTPs in achieving complete mineralization. It further proposes a reactive continuum framework (RCF) to classify contaminants by reactivity and transformation potential, thereby improving the prediction of treatment outcomes. The implications for bioaccumulation, biotransformation, and biomagnification are assessed to link contaminant behaviour with environmental risk. The RCF provides a falsifiable, molecular descriptor-based basis for predicting EC fate that removal-efficiency metrics cannot, with direct implications for reactivity-informed regulatory design under the EU Urban Wastewater Treatment Directive and equivalent frameworks globally.",

Although the environmental presence of these agricultural film components is recognized, their combined ecological risks and the subsequent management challenges they pose remain poorly understood. The present study evaluated the comprehensive toxicity effects and ecotoxicological risk implications of DEHP alone and in co-exposure with PE on earthworms within a salinized soil environment using a multi-biomarker evaluation approach. The results revealed that both treatments induced oxidative stress, DNA damage, tissue damage, and molecular responses potentially linked to growth and reproduction. Notably, DEHP\u00a0+\u00a0PE co-exposure induced stronger comprehensive toxicity effects than DEHP alone in a concentration-dependent manner under the tested salinized soil conditions. To elucidate the underlying pathways and identify potential early-warning indicators for soil monitoring, transcriptomics and molecular docking were employed. Transcriptomic profiling indicated that solitary DEHP exposure primarily disrupted digestive metabolism and cellular processes. In contrast, co-exposure to DEHP and PE significantly impaired neural and vascular development pathways. Molecular docking analysis further supported these findings by illustrating the specific binding interactions of DEHP with key target proteins. Ultimately, the current study integrates multi-level biological evidence to support ecotoxicological risk evaluation of DEHP and DEHP\u00a0+\u00a0PE co-exposure, offering potential implications for future ecological risk assessment, soil monitoring, and sustainable management of agricultural plastic residues in saline ecosystems.",

This study proposes a rigorously evaluated multimodal framework for PD detection that combines a Vision Transformer (ViT) for spiral and meander image analysis with an XGBoost classifier operating on 54 carefully engineered kinematic features extracted from multichannel handwriting signals. To assess how multimodal integration should be performed, both intermediate feature-level fusion and late decision-level fusion were evaluated under a strict 5-fold subject-wise cross-validation protocol, with supplementary sample-level analysis, on the NewHandPD dataset. The visual stream consistently outperformed the acquisition stream as a single modality, while both fusion strategies improved performance by exploiting complementary spatial (visual) and motor information. Intermediate fusion achieved the highest apparent discriminative performance, reaching 97.7% accuracy on spiral drawings and 98.5% accuracy on meander drawings, whereas late fusion provided more interpretable and modular behavior, with best subject-level results of 93.94% accuracy and AUC\u2009=\u20090.9687 for spiral, and 92.42% accuracy with AUC\u2009=\u20090.9770 for meander.

Although regular exercise is widely recognized as an important strategy to attenuate functional decline, limited evidence has simultaneously examined physical performance and body composition assessed by dual-energy X-ray absorptiometry (DEXA) in adults with Parkinson's disease participating in community-based exercise programs, particularly in Latin American settings. A cross-sectional observational study was conducted. Adults with PD participating in a community-based exercise program and community-dwelling older adults were evaluated. Physical performance was assessed using gait speed, handgrip strength, the five-times chair stand test, the single-leg balance test (SLBT), the Timed Up and Go (TUG) test, the 2-minute step test, and the Short Physical Performance Battery (SPPB). Body composition and bone mineral density (BMD) were assessed using DEXA. Propensity score matching was applied using body mass index (BMI) and sex. Descriptive statistics, Spearman correlations, and multiple linear regression models were used for data analysis. Adults with PD showed significantly lower physical performance than community-dwelling older adults, with gait speed exhibiting the largest between-group difference. In the present model, Parkinson's disease status was the strongest negative predictor of gait speed, whereas muscle strength and functional endurance were positively associated with locomotor performance. DEXA-derived lean mass was not independently associated with gait speed. Within the present sample, adults with PD participating in a community-based exercise program exhibited lower physical performance than community-dwelling older adults.

This study analyses soil samples from the McMurdo Dry Valleys collected on January 8th to 28th, 2023, and reports the first detection of nanoplastics - including polypropylene, polyethylene, polyethylene terephthalate, polystyrene, polyvinyl chloride, and tyre wear particles - using thermal desorption proton transfer reaction mass spectrometry.

But the unknown impact of inhibitors on anammox limit the application of inhibitors. In addition to the biofilm carriers used in biological nitrogen removal systems, microplastics (MPs) (a type of emerging contaminants) are the common substrate for microbial colonization, even enriched resistance genes (RGs). This research compared the effects of 0.5, 1 and 5\u202fmg/L PNCT or APAP on partial nitrification-anammox (PN/A) biofilm and plastisphere. 1\u202fmg/L PNCT inhibited the nitrogen removal functional bacteria (Nitrosomonas, Candidatus Kuenenia, Candidatus Brocadia and Nitrospira), resulting in the sharp deteriorated performance of PN/A system. 5\u202fmg/L PNCT inhibited multiple metabolism pathways, resulting in the absence of electrons and energy supply of microorganisms. 0.5-1\u202fmg/L APAP maintained the stable operation of PN/A system. Nitrospira abundances declined from 2.8% to 1.1% after 0.5\u202fmg/L APAP exposure. But 5\u202fmg/L APAP inhibited the abundance of amoA and the production of extracellular polymeric substances, which caused the slight fluctuation of PN/A performance. PN inhibitors did not cause the sharp increase of most RGs in biofilm and water. However, MPs exhibited the huge capacity of enriching RGs, which should be removed. This study proposed that 0.5\u202fmg/L of APAP was suitable for the PN/A system to control dosage for practical application.",

Evidence on sex-specific effects remains inconsistent. We analysed 528 mother-child pairs from a Korean birth cohort. Maternal urinary BPA concentrations were measured during mid-pregnancy. Children's BMI and BMI Z-score were assessed at ages 2, 4, 6, 8, and 10\u2009years. Associations were estimated using linear and mixed-effects models, stratified by sex and adjusted for maternal and child covariates. The mean maternal BPA concentration was 2.3\u2009\u03bcg/g creatinine. BPA exposure was positively associated with BMI and BMI Z-score in boys but negatively associated in girls. At age 10, this divergence was most apparent. Mixed-effects models showed a 0.13\u2009kg/m2 (95% CI: 0.01, 0.25) increase in BMI among boys and a 0.20\u2009kg/m2 (95% CI: -0.32, -0.08) decrease among girls per 1-unit increase in log-transformed BPA. Similar patterns were observed for BMI Z-score. Prenatal BPA exposure exhibited sexually dimorphic associations with BMI from early childhood to age 10. These findings underscore the importance of considering sex-specific effects in environmental health research and support policies to reduce BPA exposure during pregnancy.",

We developed a reproducible operationalization that translates the 13-item Diagnostic Criteria for Advanced Parkinson Disease questionnaire into structured variables and generates longitudinal labels capturing certainty of advanced disease. In the Parkinson's Progression Markers Initiative near-diagnosis cohort (n\u2009=\u20091,302; up to 13 years), we applied this pipeline to characterize label trajectories and face validity over time. As a proof of utility, we used baseline clinical and genetic features to forecast advanced disease at years 7-11, explicitly separating forecasting from contemporaneous staging. Using a binary long-horizon endpoint, the best year-9 model showed an area under the receiver operating characteristic curve of 0.89 (95% CI 0.81-0.97). In an independent real-world cohort with \u2265\u200911 years follow-up (n\u2009=\u200935), discrimination attenuated (0.55-0.61), consistent with dataset shift and limited event counts.",

This review summarizes current in vivo mammalian evidence on NP-induced cellular toxicity and organ-specific histopathological changes based on a structured literature search of PubMed, Scopus, and Web of Science covering studies published between 2000 and 2024. The findings were narratively organized by organ system. Across the nervous, respiratory, gastrointestinal, hepatobiliary/renal, and reproductive systems, NPs consistently induce common pathological signatures, including immune cell infiltration, apoptosis, fibrosis, epithelial barrier disruption, and ultrastructural organelle damage. These lesions indicate conserved mechanisms involving oxidative stress, inflammatory signaling, impaired cellular homeostasis, and organ-organ crosstalk, such as gut-liver and hepato-renal interactions, which may amplify systemic toxicity. Collectively, the evidence demonstrates that nanoplastics act as system-wide toxicants capable of multi-organ histopathological disruption, distinct from larger microplastics or other nanoparticles, underscoring the need for further mechanistic and pathology-driven evaluation.",

However, its overarching \"green\" reputation often obscures latent food safety concerns. Under complex thermal and humid storage conditions, PLA packaging is highly susceptible to in-situ degradation, precipitating the release of microplastics (MPs) and low-molecular-weight migrants-such as oligomers and functional additives-directly into food matrices. This review critically assesses these often-overlooked ingestion risks and their chronic health implications. By systematically linking PLA synthesis pathways and microstructural degradation mechanisms to dynamic migration behaviors, we delineate the specific toxicological pathways activated by these migrants. Although synthesized primarily via ring-opening polymerization to ensure stability, PLA undergoes hydrolysis in food-contact environments. Emerging toxicological evidence robustly correlates these migratory degradation intermediates with severe physiological disruptions, including intestinal barrier dysfunction, systemic oxidative stress, and immune dysregulation. Consequently, current regulatory frameworks-which predominantly focus on macroscopic material disintegration-are insufficient to address the complex biochemical toxicity of intermediate degradation products. To bridge this gap, this review evaluates sustainable risk mitigation strategies, advocating for the establishment of strict, specific migration limits (SMLs). Ultimately, we emphasize the urgent necessity for a paradigm shift toward active \"Safety-by-Design\" frameworks, ensuring that the ecological benefits of biodegradable packaging are not achieved at the expense of human dietary health.",

After release into aquatic systems, photo-oxidation, mechanical abrasion, fragmentation, and biofilm-associated aging modify their surface chemistry, morphology, polarity, and reactivity. Simultaneously, natural organic matter, humic substances, extracellular polymeric substances, proteins, lipids, and microbial products adsorb onto plastic surfaces, forming eco-coronas that regulate aggregation, colloidal stability, contaminant partitioning, and desorption behavior. A central unresolved question is how eco-corona-coated particles are remodeled after organismal entry, how environmental coronas are exchanged into bio-coronas within mucus, gut, gill, and tissue microenvironments, and how these dynamic interfaces control the toxicokinetics of coexisting pollutants. This review synthesizes current evidence to define when weathered microplastics and nanoplastics act as vectors, sinks, amplifiers, or neutral carriers of co-pollutants. We emphasize internal exposure, bioaccessibility, residence time, and tissue distribution rather than nominal water concentrations or adsorption capacity alone. Classical modeling indicates that, for many hydrophobic organic contaminants, chemical flux from natural prey, sediments, and organic matter may exceed that from ingested plastics under typical environmental conditions, requiring scenario-specific interpretation. However, this logic should not be generalized to antibiotics, pharmaceuticals, metals, and per- and polyfluoroalkyl substances, whose interactions may depend on electrostatics, ionization, hydrogen bonding, cation bridging, corona chemistry, and gut-phase desorption. We propose a predictive framework linking plastic aging, eco-corona formation, bio-corona remodeling, partitioning/desorption kinetics, uptake, retention, translocation, and organism-level outcomes. Finally, within an explicitly aquatic scope, we outline minimum reporting requirements to improve comparability, mechanistic interpretation, and risk relevance in microplastic-mixture toxicology, including clearer reporting of particle-size class, size distribution, hydrodynamic diameter after corona formation, and size-dependent uptake or translocation outcomes.",

Transforming it into uniform lignin colloidal spheres (LCSs) with ordered arrays enables specific visible light reflection and thus presents tunable colors. However, industrial lignin-derived LCSs via self-assembly typically exhibit broad size distribution and poor solvent resistance. To address these challenges, we proposed a novel strategy combining solvent fractionation and surface covalent polymerization. Acetone/water fractionation effectively reduced lignin heterogeneity, narrowing LCSs size distribution. Bisphenol A diglycidyl ether (BADGE) was used as cross-linker to covalently polymerize hydroxyl groups, inhibiting LCSs dissolution. Two hybrid LCSs were fabricated: hy-LCSs via co-self-assembly of lignin and BADGE and hy@LCSs through subsequent surface cross-linking. Hy-LCSs20 (20\u2009wt% BADGE) shows stability in pH 12 alkali and acetone/water, while hy@LCSs70 exhibited unprecedented alkaline resistance up to pH 14, far exceeding the highest reported value of pH 12 for lignin colloidal spheres to date. Critically, BADGE incorporation preserved monodispersity of both hy-LCSs20 and hy@LCSs70, enabling precise size control without compromising uniformity. After centrifugation to form ordered structures, both hy-LCSs20 and hy@LCSs70 reflect specific wavelengths with tunable colors, overcoming key barriers in lignin valorization.",

It is now clear that FOG is not a monolithic phenomenon but instead exhibits substantial heterogeneity across patients, suggesting the existence of subtypes. Among the heterogeneous features are levodopa response patterns and nonmotor features, cognitive impairment and anxiety/depression. It remains an open question as to whether these phenotypes are the result of different pathophysiology. In this paper, we develop the hypothesis that levodopa response patterns may identify FOG subpopulations tied to nonmotor symptoms and alterations in different neurotransmitter systems. Here, we review the levodopa response patterns of FOG seen in PD based on a rigorous levodopa challenge paradigm using a 40% higher dose of levodopa and blood levodopa levels to demonstrate that the majority of patients are either levodopa responsive (OFF-FOG) or unresponsive (ONOFF-FOG). The literature demonstrates that executive and affective changes are not universal in FOG and actually relate closely to levodopa response patterns, OFF-FOG is associated with affective disorders, and ONOFF-FOG is related to cognitive decline. In turn, OFF-FOG and affective disorders appear to be associated with brain noradrenergic degeneration, whereas ONOFF-FOG and cognitive decline are associated with cholinergic loss. These observations suggest different therapeutic targets by subtype. We suggest that levodopa challenge testing may help stratify FOG patients in trials and mechanistic studies.",

However, current boron carriers, such as sodium borocaptate (10BSH), suffer from inadequate tumor specificity. Herein, the present study details the design, synthesis, and preclinical evaluation of a novel small-molecule boron-10-enriched carrier, which was synthesized by covalent bond coupling 4-carboxy-3-fluorophenylboronic acid (FPBA) to 10BSH (FPBA-BSH), achieving a boron content of approximately 25 wt.%. FPBA-BSH efficiently penetrated the blood-brain barrier and demonstrated pronounced accumulation in orthotopic gliomas, achieving a boron concentration of 75.4 \u03bcg-B/g-tumor tissue, which was 4.2- and 3.7-fold higher than those with boronophenylalanine (BPA) and BSH, respectively. Moreover, FPBA-BSH exhibited markedly improved tumor selectivity, with tumor-to-normal tissue (T/N) and tumor-to-blood ratios of 52.0 and 7.2, respectively. The T/N ratio was approximately 19.3- and 14.1-fold greater than those observed for BPA and BSH. In the melanoma model, FPBA-BSH achieved an intratumor boron concentration of 114.4 \u03bcg-B/g-tumor tissue, representing 8.4- and 9.9-fold increases compared with BPA and BSH, respectively. Correspondingly, the T/N and tumor-to-blood ratios reached 135.1 and 8.6, indicating substantially enhanced tumor targeting and retention. The T/N ratio achieved with FPBA-BSH was approximately 26.0- and 34.6-fold higher than those obtained with BPA and BSH, respectively. Consistent with its superior tumor selectivity, FPBA-BSH-mediated BNCT induced pronounced tumor-selective cytotoxicity and markedly inhibited tumor growth in both orthotopic glioma and melanoma models compared with BPA, BSH, and untreated controls. These findings demonstrate that FPBA-BSH represents a promising small-molecule boron delivery agent with substantial potential for clinical BNCT applications.",

Here, we compared tPODs for bisphenol A (BPA) across multiple HTTr studies conducted in MCF-7 breast cancer cells, including datasets from our laboratory and others. Although these studies employed broadly similar approaches, they differed in key methodological features, including estrogen-depletion protocols, exposure duration, and maximum test concentration. Using a standardized downstream bioinformatic workflow, we evaluated the consistency of BPA transcriptomic potency estimates and assessed factors contributing to variability across studies. Overall, five of seven studies yielded BPA potency estimates within a similar concentration range, supporting the utility of HTTr for comparative potency assessment despite some inter-study variability. Notably, studies conducted under estrogen-depleted conditions yielded higher potency estimates relative to those performed under standard culture conditions. Similarly, longer exposure durations were associated with higher potency estimates. These findings indicate that, while tPODs are generally reproducible across HTTr studies, experimental conditions, particularly estrogen depletion and exposure duration, can influence potency estimates in MCF-7 cells. However, these factors were not systematically varied or independently controlled across datasets, and therefore their individual contributions cannot be definitively disentangled in the present analysis. This work highlights the importance of standardizing hormone conditions and exposure durations when applying HTTr to screen estrogenic chemicals. Collectively, these results support the use of HTTr for chemical prioritization while underscoring the need for harmonized experimental design in endocrine-relevant in vitro models.",

Here, we show that although the total additive mass is generally lower in TWPs from retreaded tires, these particles exhibit a markedly greater additive leaching potential, particularly for p-phenylenediamines (PPDs). Notably, the highly water-soluble additive N-isopropyl-N'-phenyl-p-phenylenediamine (IPPD), present at high concentrations in some retreaded-tire TWPs, is especially leachable. Correspondingly, leachates from retreaded-tire TWPs cause greater growth inhibition in Vibrio fischeri and Chlorella vulgaris than those from new or used tires. Furthermore, our numerical model projections under the Shared Socioeconomic Pathway 2 (SSP2) scenario show that global emissions of retreaded-tire TWPs could increase several hundred-fold by 2060. The substantial and growing risks identified in our study underscore the urgent need for broader investigations into the environmental impacts of these particles.",

A convolutional neural network (CNN) was applied to classify impact and non-impact BPA patterns. A combination of BPA patterns generated by the researcher were supplemented by open-source BPA datasets and used for the CNN training. This methodology yielded promising results of up to 79% accuracy over 10 folds, validating the feasibility of such research avenues in the field. Furthermore, saliency maps were applied as the CNN's explainability layer, which is a novel application of XDL in BPA interpretations. The study highlights the potential of a novel BPA research stream in XAI while also underscoring the potential of the model to act as a possible reliable alternative tool for BPA experts over manual classification methodologies. This approach does not aim to replace the human element from the forensic science process but rather provide a tool to BPA experts to aid and expedite BPA interpretations without compromising on explainability metrics. It has the potential to increase transparency and trust in deep learning systems, which in turn would increase the reliability of forensic outcomes.",

In this study, a visible-light-responsive photocatalyst based on MnO2 coupled with defective graphitic carbon nitride (MnO2/def-g-C3N4) was rationally designed for photocatalytic decomposition of 50 mg L-1 of BPA and 40 mg L-1 of MLT in water. Structural characterizations viz. XRD, XPS, Mott-Schottky analysis, UV-visible, AFM, SEM and TG-DTA etc. confirmed the successful formation of the p-n heterojunction with abundant surface defects, enhanced light absorption, and improved charge-carrier separation. The optimized MnO2/def-g-C3N4 (DCN-MnO2) composite exhibited conspicuously suppressed charge recombination and increased photoactivity under visible-light irradiation that showed rapid photodegradation efficiencies of BPA and MLT. The photocatalyst also demonstrated good stability and recyclability over four cycles with minimal activity loss. Mechanistic investigations suggested that the synergistic interaction between MnO2 and defective g-C3N4, along with defect-mediated charge transfer pathways, played a crucial role in enhancing photocatalytic performance. This work highlights MnO2/def-g-C3N4 as an efficient and sustainable visible-light photocatalyst for the decomposition of emerging organic contaminants in wastewater, offering promising potential for environmental remediation applications.",

Neuropsychiatric adverse events (AEs) have been reported in both clinical trials and real-world studies, with some real-world cohorts suggesting higher rates among patients with prior hallucinations or cognitive impairment. The present study aimed to determine the incidence and risk factors of neuropsychiatric AEs in a large prospective real-world cohort. We analyzed data from the DATs-PD GETM Spanish Registry, an observational, prospective, multicenter, open-label study. 214 patients treated with LDp/CDp CSI were included. Median age was 69\u2009years, and median disease duration was 12\u2009years. At baseline, 35% had cognitive impairment, 25.7% hallucinations/psychosis, and 26.2% impulse control disorders (ICDs). During follow-up after initiation (median 163\u2009days), 19.2% developed at least one neuropsychiatric AE, mostly mild-moderate, and only 2.3% required device removal. Most events occurred more than 1\u2009month after treatment initiation. In adjusted Cox, none of the evaluated variables were associated with the development of hallucinations/psychosis/confusion. The presence of ICD at baseline was associated with an increased risk of ICD-related AEs. Neuropsychiatric AEs, mainly hallucinations/psychosis, occurred in a clinically relevant proportion of patients treated with LDp/CDp CSI. However, they were generally mild-to-moderate and rarely led to treatment discontinuation. Except for ICD, baseline cognitive and psychotic features were not associated with higher incidence. These findings support its use in appropriately selected patients while highlighting the importance of individualized careful clinical monitoring.",

We developed image-guided convection-enhanced delivery with real-time monitoring to improve intraputaminal distribution of neurotrophic gene therapy. To evaluate the 5-year safety and tolerability of bilateral putaminal delivery of adeno-associated virus serotype 2 encoding glial cell line-derived neurotrophic factor (AAV2-GDNF), and to describe exploratory long-term clinical outcomes.

Herein, we propose a synergistic nano-confinement and physical-field-modulation strategy that enables concurrent acceleration of solar-driven evaporation of water and on-site remediation of organic pollutants. Implemented in hollow mesoporous carbon nanocages integrated with Fe-N4 catalytic sites and inner wall plasmonic Au nanoparticles, the system couples mesoporous confinement with localized thermal and pressure perturbations to transform bulk water into thermodynamically activated intermediate states and substantially reduce the effective vaporization enthalpy. This integrated framework delivers high evaporation rates of 2.56\u00a0kg\u00a0m-2\u00a0h-1 in planar devices and 6.84\u00a0kg\u00a0m-2\u00a0h-1 in 3D architectures under one-sun irradiation, with a\u00a0kinetic enhanced Hertz-Knudsen-Schrage-derived evaporation coefficient.

However, the mechanistic involvement of polyethylene (PE) and polypropylene (PP) MPs in GBA-associated neurotoxicity remains insufficiently understood. Therefore, the present study aimed to evaluate the impact of PE- and PP-MPs on intestinal barrier integrity, oxidative stress, neuroinflammation, and synaptic dysfunction. Following physicochemical characterization, experimental animals were orally exposed to PE- and PP-MPs (10 and 100\u00a0mg/kg BW) for 45 consecutive days. MP exposure significantly disrupted intestinal barrier integrity, reduced zonula occludens-1 expression, and altered short-chain fatty acid profiles, indicating impaired gut microbial metabolic activity. Concurrently, oxidative stress and inflammatory responses were evidenced by reduced antioxidant defence, increased lipid peroxidation, elevated inflammatory mediators, and altered neurochemical markers in small intestine and brain tissues. Behavioral abnormalities, increased amyloid precursor protein (APP) expression, tau-associated pathological alterations, and histopathological changes further indicated GBA impairment following MP exposure. Notably, PE-MPs produced comparatively greater toxicological effects than PP-MPs, particularly at higher dose. Overall, the findings demonstrate that chronic exposure to environmentally relevant PE- and PP-MPs disrupts intestinal homeostasis and promotes neuroinflammatory toxicity through GBA dysregulation.",

This review synthesizes current knowledge on the sources, pathways, detection methodologies, occurrence, tissue distribution, ecotoxicological effects, and human health implications of microplastics in freshwater fish. Major sources of MPs include urban wastewater, industrial effluents, agricultural runoff, aquaculture activities, and atmospheric deposition, which facilitate their entry into rivers, lakes, reservoirs, and wetlands. Advances in analytical techniques such as Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and pyrolysis-gas chromatography/mass spectrometry have improved MP detection; however, methodological inconsistencies continue to hinder data comparability. Globally, freshwater fish frequently ingest MPs, with fibers and fragments being the dominant morphotypes and polyethylene, polypropylene, polyethylene terephthalate, and polyamide the most common polymers. Beyond the gastrointestinal tract, MPs have been detected in gills, liver, muscle, gonads, and eggs, indicating potential translocation and reproductive transfer. Exposure to MPs can induce oxidative stress, tissue damage, metabolic disturbances, and reproductive impairment in fish. Furthermore, consumption of contaminated fish may expose humans to MPs and associated pollutants, raising concerns regarding food safety and public health. The review identifies key research gaps and highlights the need for standardized methodologies, long-term monitoring, risk assessment frameworks, and integrated mitigation strategies to protect freshwater biodiversity, fisheries, and food security.",

Gut microbiota is considered a contributing factor to multiple hepatic injuries. However, its role in NPs-induced hepatic injuries remains unclear, and microbial intervention strategies are required. Our results reveal that oral exposure to polystyrene NPs reduces gut probiotic Bifidobacterium pseudolongum (B.p) and its metabolite inosine. Gut microbiota from NPs-administered mice partially reproduces NPs-related impairment of gut homeostasis and hepatic injury in recipient mice. Moreover, B.p colonization improves NPs-induced gut homeostasis impairment and hepatic injury, and its protective effects are reproduced by supplementation with inosine. Mechanically, B.p colonization increases hepatic level of inosine and subsequently normalizes the expression of its target A2AR. Meanwhile, increased inosine inhibits the miR155/SOCS1/NF-\u03baB pathway and represses NPs-induced M1 macrophage polarization. CGS21680, an agonist of A2AR, effectively represses lipopolysaccharide (LPS)-induced M1 macrophage polarization and inhibits the miR155/SOCS1/NF-\u03baB pathway in vitro. Further, miR155 knockout inhibits NPs-induced M1 macrophage polarization, but does not influence the suppression of NPs on A2AR. These findings suggest that B.p-derived inosine can repress NPs-induced M1 macrophages polarization by inhibiting the miR155/SOCS1/NF-\u03baB pathway via targeting A2AR. Altogether, this study further clarifies the role of gut microbiota in NPs-induced hepatic injury and provides a potential microbial therapeutic strategy.",

Alexander technique is a non-exercise, cognitive embodiment training common in performing arts. Studies have shown it to have physical benefits including pain reduction and improved balance and coordination, as well as non-physical benefits like increased wellbeing, confidence, and agency. We assessed feasibility and preliminary efficacy of an Alexander-based group course for care partners of people living with neurodegenerative disease. We conducted a single-arm multi-site study of eight Alexander-based group courses for informal care partners of people living with Parkinson's (63 began course; 45 remained at 6-month follow-up). Classes met weekly for 90-120\u00a0min over 10\u00a0weeks in community settings in North Carolina, USA. Outcomes were assessed before and after the intervention and 6\u00a0months later. Self-regulation strategies were taught through group, partnered, and individual activities. Participants practiced interrupting automatic reactions to stressful stimuli in everyday contexts and learned skills to observe and improve psychomotor patterns. Outcome measures included course attendance and retention, anonymous course evaluations, three cognitive measures, a balance assessment, and 12 self-report measures. Alpha was set at 0.0031 to correct for multiple comparisons. Course attendance was 85%. Retention was 84%. Participants enjoyed the course and the group interactions.

The objective of this study was to assess the rate of internal pulse generator (IPG) implantation for sacral neuromodulation (SNM) in patients with CNS pathology with overactive bladder (OAB) or urinary retention in women. This was a retrospective study utilizing the TriNetX Research Network platform, using the years 2010 to 2025, collected on March 27, 2025. Two separate queries of the data set were performed to obtain our cohorts due to the differences in inclusion criteria and endpoints. For our OAB cohorts, adult (18 years or older) female participants were included in the study if they had OAB, urge incontinence, or urgency of urination via International Classification of Diseases (ICD) codes. We then developed 6 cohorts for (1) dementia, (2) Parkinson disease, (3) stroke, (4) multiple sclerosis (MS), (5) normal pressure hydrocephalus (NPH), and (6) an aggregate cohort. We utilized ICD codes and medication codes for the aforementioned diagnoses. Each cohort had either stage 1 SNM placement or peripheral nerve evaluation (PNE) via Current Procedural Terminology (CPT) codes after 2010. Control participants included all female adult participants without any of the aforementioned neurological diagnoses. The primary outcome was the rate of neurostimulator device IPG placement within 1 month of stage 1 or PNE. A second group of cohorts was developed for urinary retention. Adult female participants were included in the study if they had retention of urine. We developed 4 cohorts: (1) dementia, (2) Parkinson disease, (3) stroke, and (4) MS, utilizing the previous ICD codes and medications. Each cohort had either stage 1 SNM placement or PNE placed after 2010. The primary outcome was the rate of neurostimulator device IPG placement (CPT code 64590) within 3 months of stage 1 or PNE. Compared with the control (4,337 of 7,805, 55.56%), there was a statistically significant reduction in the rates of SNM IPG implantation in patients with dementia (179 of 375, 47.73%) and the aggregate (483 of 984, 49.09%). There was no significant difference in SNM IPG implantation for the Parkinson disease, stroke, MS, and NPH cohorts. In the urinary retention group, compared with the control population, there were no statistically significant differences in the rate of SNM IPG implantation in the cohorts. Our study suggests that SNM has equal efficacy in patients with CNS pathology with OAB or urinary retention, similar to the nonneurogenic population, except in patients with dementia, who have lower rates of IPG implantation for OAB.",
        "42407160": "ID: 42407160\nTitle: Detection and cross-organ characterization of physiological response to microplastic stress in Panax ginseng based on hyperspectral imaging assisted with machine learning.\nAbstract: Microplastic pollution can affect growth and quality of medicinal plants, yet rapid detection of microplastic stress responses remains underexplored. We treated ginseng with polyethylene microplastics, acquired leaf hyperspectral images (HSI) on day 23, and constructed machine learning models for identifying stress levels and predicting physiological indicators. Furthermore, the applicability of successive projections algorithm (SPA) and competitive adaptive reweighted sampling (CARS) for characteristic wavelength selection was compared. Results showed that polyethylene stress significantly affected the physiological state. The classification models effectively identified microplastic stresses of different concentrations, with the support vector machine (SVM) model performing the best (accuracy of 85.2%). For quantitative prediction, the partial least squares regression (PLSR) model exhibited optimal performance for indicators including chlorophyll (Chl) (RPD\u202f=\u202f3.98), soluble sugar (RPD\u202f=\u202f2.56) and peroxidase (POD) (RPD\u202f=\u202f2.89), and the convolutional neural network performed better in superoxide dismutase (SOD) prediction (aerial RPD\u202f=\u202f3.27, underground RPD\u202f=\u202f2.65). Leaf spectral data enabled prediction of aerial and underground physiological indicators (RPD\u202f=\u202f2.10 to 2.73), indicating that aerial spectral information reflected underground physiological state. Characteristic wavelength selection results showed that SPA had advantages for SOD prediction, while CARS performed better for the remaining seven indicators (RPD >2.0). In conclusion, HSI combined with machine learning models enabled rapid nondestructive identification of microplastic stress responses and prediction of key physiological indicators in ginseng, suggesting quantifiable relationships between aerial spectral data and underground physiological states. This study provides a technical prototype for the growth detection of medicinal plants.",
        "42407165": "ID: 42407165\nTitle: Ocean warming shapes the marine plastisphere: Microbial assembly, vector effects, and biogeochemical feedbacks of microplastics.\nAbstract: Marine microplastic pollution has evolved into a global ecological crisis, shifting from physical contamination to microbial habitats on plastic surfaces. The colonization of microorganisms on synthetic surfaces is not random but is driven by physicochemical and biological factors. This narrative review summarizes the properties of microplastics that influence the composition and assembly of microbial communities. We emphasize that polymer types (e.g., polyethylene and biodegradable polylactic acid) act as primary templates, whereas surface interface properties, including hydrophobicity and adsorption of natural organic matter and biomolecules, determine attachment kinetics. We address the size-dependent effects of microplastics, focusing on how nanoscale particles cause greater oxidative stress than micron-scale particles. Beyond community structuring, microplastics serve as vectors facilitating the long-distance migration of marine pathogens and the horizontal transfer of antibiotic resistance genes, thereby expanding the geographical range of ecological risks. Significantly, bidirectional interactions within the plastisphere (the microbial community and associated biofilm that develop on plastic surfaces) reshape marine biogeochemical cycles. By altering the buoyancy and sinking rates of organic aggregates in the water column, microplastic-microbe aggregates perturb the biological carbon pump and modulate nitrogen transformation processes. This review provides an updated framework that integrates ocean warming into predictive ecological models for plastisphere assembly and function, addressing a gap in climate-microplastic research. Using mechanistic insights from 2010 to 2025, we identify critical knowledge gaps and advocate for advanced multi-omics and stable isotope probing to characterize the functional metabolic pathways of the plastisphere in a changing ocean."
