Specific 3-O-sulfation patterns on heparan sulfate proteoglycans (HSPGs) mediate tau fibril internalization. Novel enzymatic modulators that selectively reduce 3-O-sulfation while preserving essential HSPG functions could block tau cellular uptake without disrupting normal cellular processes.

TREM2 deletion enhances tau dispersion through pathogenic microglial exosomes. A tetravalent TREM2 agonist could reprogram microglial exosome cargo from tau-spreading vesicles to protective, tau-degrading vesicles while enhancing phagocytic clearance of extracellular tau.
