Deficits in Reelin expression and signaling play a pathogenic role in Alzheimer’s disease (AD). Thus, strategies aimed at correcting Reelin deficits may provide a novel therapeutic approach to treating AD. The cysteine-rich, whey protein supplement, Immunocal®, has recently been shown to rescue Reelin expression in a mouse model of Schizophrenia. Given that Reelin-expressing neurons of the entorhinal cortex region are a highly vulnerable population of cells that are lost early in AD, we examined the effects of Immunocal® in the hippocampal-entorhinal cortex formation in a mouse model of AD. Glutathione levels and Reelin expression in the hippocampal-entorhinal cortex formation (entorhinal …

Neuronal cell death via apoptosis or necrosis underlies several devastating neurodegenerative diseases associated with aging. Mitochondrial dysfunction resulting from oxidative or nitrosative stress often acts as an initiating stimulus for intrinsic apoptosis or necrosis. These events frequently occur in conjunction with imbalances in the mitochondrial fission and fusion equilibrium, although the cause and effect relationships remain elusive. In this thesis, I demonstrate in primary rat cerebellar granule neurons (CGNs) that oxidative or nitrosative stress induces an N-terminal cleavage of optic atrophy-1 (OPA1), a dynamin-like GTPase that regulates mitochondrial fusion and maintenance of cristae architecture. This cleavage event is indistinguishable from …
