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.

PS exposure alone is insufficient for selective tau targeting; a dual-signal mechanism exists where externalized PS recruits microglia while exposed tau N-termini (truncated by caspases) serve as the specific eat-me signal. Therapeutic strategies should develop bispecific constructs recognizing both PS and specific tau neoepitopes simultaneously, avoiding off-target effects in stressed-but-non-tau tissues.
