Abstract:Aside from being an integral protein involved in the synthesis and hydrolysis of ATP, Ecto-F1-ATPase plays a role in cholesterol homeostasis. We demonstrated the presence of autoantibodies to ecto-F1-ATPase (ASabs) in sera and cerebrospinal fluids from patients with Alzheimer's disease (AD). Herein we show that ASabs, unlike irrelevant antibodies, can increase cellular uptake of HDL, a risk factor for the development of AD, via a mechanism involving the prototypical function of ecto-F1-ATPase: the generation o…
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.
