Novel Therapeutic Hypotheses for 4R-Tau Strain-Specific Spreading in PSP vs CBD
1. Glial Glycocalyx Remodeling Therapy
Description: PSP and CBD tau strains differentially interact with region-specific glial glycocalyx compositions, determining astrocytic morphology. Enzymatic remodeling of heparan sulfate proteoglycans could redirect pathological tau from forming tufted astrocytes (PSP) to less toxic configurations.Target: HSPG2 (perlecan), EXT1/EXT2 (heparan sulfate biosynthesis...
