α7 Nicotinic Acetylcholine Receptor Relieves Angiotensin II–Induced Senescence in Vascular Smooth Muscle Cells by Raising Nicotinamide Adenine Dinucleotide–Dependent SIRT1 Activity

Abstract

Our results demonstrate that activation of α7nAChR alleviates Ang II-induced VSMC senescence through promoting NAD(+)-SIRT1 pathway, suggesting that α7nAChR may be a potential therapeutic target for the treatment of Ang II-associated vascular aging disorders.
