NADPH Oxidase Plays a Central Role in Blood-Brain Barrier Damage in Experimental Stroke

Abstract

Activation of Rac and subsequently of the gp91phox containing NADPH oxidase promotes cerebral ROS formation, which then leads to Rho kinase-mediated endothelial cell contraction and disruption of the BBB. Inhibition of NADPH oxidase is a promising approach to reduce brain injury after stroke.
