Traumatic Brain Injury Causes Endothelial Dysfunction in the Systemic Microcirculation through Arginase-1-Dependent Uncoupling of Endothelial Nitric Oxide Synthase.
RatTBIUnspecifiedSprague-DawleyMaleApplied ex vivo to arteries isolated 24 h after injury
Model: Traumatic brain injury with assessment of mesenteric artery function 24 h later
Traumatic brain injury impaired endothelium dependent dilation of mesenteric arteries through arginase driven eNOS uncoupling, and exogenous L-arginine or arginase inhibition restored endothelial function.
