In this regard, in the future it will be interesting to study the balance of markers of BBB permeability impairment (neuron-specific enolase (NSE), GFAP, α-glycoprotein, etc.), inflammation markers in the peripheral blood after a stroke and their correlation with the level of APP and Aβ in the brain and blood in the recovery period. The gene discussed is GFAP; the disease is Stroke.
