WebJul 29, 2013 · Tau and TAT contain heparin-binding domains, and it is established that TAT enters cells via HSPG-mediated macropinocytosis (20–25). Given the extensive colocalization between tau fibrils and TAT after endocytosis, we hypothesized that HSPGs might also mediate cellular binding and internalization of tau aggregates.

Experimental procedures Chemicals and reagents Baicalein, ThS, ANS, BES, and MTT were purchased from Sigma. WebMar 4, 2024 · Many neurodegenerative diseases, including Alzheimer’s disease, the most common form of dementia, are characterised by knotted clumps of a protein called tau. In these diseases, tau misfolds, stacks together and forms abnormal filaments, which have a structured core and fuzzy coat.
