(Submitter supplied) Roles of reactive perivascular astrocytes in dysregulation of the blood-brain barrier (BBB) function and cerebral perfusion are not well defined. Here, we investigated transformation of reactive astrocyte function for vascular repair after ischemic stroke by targeted deletion of astrocytic Na+/H+ exchanger isoform 1 in Gfap-CreERT2+/-;Nhe1f/f (Nhe1 Astro-KO) mice. Control Gfap-CreERT2+/-;Nhe1f/f (wild-type) mice displayed BBB damage (elevated endothelial transcytosis and intracellular vesicles) and persistent cerebral hypoperfusion in an ischemic stroke model (transient middle cerebral artery occlusion).
