WebFeb 8, 2024 · Paired helical filaments (PHFs) from the Alzheimer's disease (AD) brain are highly ubiquitinated and ubiquitination likely plays a vital role in tau filament formation. Whether tau ubiquitination is the causality or consequence of the disease in AD remains elusive. The following questions are worth considering: What does the extent of tau … WebMar 28, 2024 · Sarkosyl insoluble fibrillar tau is comprised of paired helical filaments seen by electron microscopy (EM), and is more resistant to proteinase K, compared to HMW tau which presents only sparse, short, filaments. Sarkosyl insoluble and HMW tau are nearly equivalent in potency in a HEK cell bioactivity assay for seeding aggregates. Injection of ...
