WebDec 20, 2024 · LRP1 is a receptor for tau that mediates tau uptake, degradation, and seeding of intracellular tau aggregation. We previously found that LRP1 binds … Webspanning protein LRP1 acts as a receptor for both normal (physiological) tau and for short strings (oligomers) of misfolded tau. Binding between LRP1 and tau leads to the uptake of tau into neurons and its spread through connected neuronal networks. Once internalized, tau resides in membrane-bound compartments called endosomes.
