plasma GFAP separates causal from compensatory states in: Blood-brain barrier p…

Mechanistic description

A longitudinal biomarker panel centered on plasma GFAP can distinguish harmful mechanisms from protective adaptation. The decisive experiment is to measure plasma GFAP before and after endothelial exosome profiling in stratified models.
