Different brain regions exhibit varying microglial PS-receptor expression profiles (e.g., higher CX3CR1+ microglia in hippocampus with more efficient PS clearance). Tau pathology in regions with lower PS-sensing capacity leads to accumulation of PS-exposed neurons, explaining regional vulnerability patterns. Selectivity derives from region-specific microglial states.

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.
