Experiment #00000055

If the RGNEF NF 242 Terminal loses its functional ability to agitate or compete with TDP-43, perhaps from misfolding or sequestration, could it cause the TDP-43 proteinopathy seen in the retina, post-mortem, in Sporadic Amyotrophic Lateral Sclerosis patients, if the RGNEF failures were localized in the retina?

Experiment #00000012

If a toxin with a thermodynamic affinity for Zinc GREATER THAN that of Glutamate AND LESS THAN that of RGNEF, under certain conditions a pathway exists wherein the toxin could shuttle synaptic retinal zinc to RGNEF, thus potentially ultimately resulting in the retinal TDP-43 proteinopathy seen in the retina post mortem in Sporadic Amyotrophic Lateral Sclerosis
