Monomeric soluble tau does not induce PS exposure; PS externalization specifically occurs when tau undergoes liquid-to-solid phase transition (condensate formation or fibrillization). This aggregate-state specifically alters membrane curvature and local lipid organization, triggering scramblase recruitment. This explains why early tau pathology may not show PS exposure.

PS exposure functions as a universal danger-associated molecular pattern but its downstream interpretation differs by cell type. In neurons, PS triggers anti-inflammatory engulfment (neuroprotective); in microglia, PS indicates activation state. Targeting strategies should focus on neuronal-specific PS-binding receptors rather than PS itself.
