Abstract:Cerebral arteries adapt to chronic hypoxia by altering the phenotypes of the plastic and heterogeneous population of cells in the artery wall. Perivascular nerves also undergo differentiation during hypoxia and alter vasotrophic effects on arteries. Here we test the hypothesis that nerves from the superior cervical ganglia (SCG) mediate hypoxic remodeling of ovine cerebral arteries. Using a chronic hypoxia (CH) and unilateral sympathectomy (SANX) model, we tested effects of CH and SANX on tone, contractile pro… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
