Autophagy dysfunction has been implicated in misfolded protein accumulation and cellular toxicity in several diseases. Whether alterations in autophagy also contribute to the pathology of lipid storage disorders is not clear. Here we show defective autophagy in Niemann-Pick type C1 (NPC1) disease associated with cholesterol accumulation, where maturation of autophagosomes is impaired due to defective amphisome formation caused by failure in SNARE machinery, whilst the lysosomal proteolytic function re…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
