C. elegans Presenilin Mediates Inter-Organelle Contacts and Communication that Is Required for Lysosome Activity
Abstract:Compromised lysosome function is implicated in the pathology of many neurodegenerative diseases, including Alzheimer's disease (AD). Familial Alzheimer's disease (fAD) is caused primarily by mutations in the presenilin encoding genes, but the underlying mechanism remains obscure. Loss of the conserved C. elegans presenilin orthologue SEL-12 results in increased mitochondrial calcium, which promotes neurodegeneration. Here, we find that sel-12 mutant lysosomes, independent of SEL-12 proteolytic activity, are si… Show more
