MicroRNA-Mediated Therapy Modulating Blood–Brain Barrier Disruption Improves Vascular Cognitive Impairment

Abstract

We here provide the first evidence that the TNFα-miR-501-3p-ZO-1 axis plays an important role in the pathogenesis of cerebral hypoperfusion-induced working memory deficits and white matter lesions, as a result of blood-brain barrier breakdown via tight junction disruption. Therapeutic manipulation of miR-501-3p holds promise for limiting vascular cognitive impairment progression.
