WebbThe senescence of vascular endothelial cells (ECs) is characterized as a hallmark of vascular aging, which leads to the initiation, progress, and advancement of cardiovascular diseases. However, the mechanism of the ECs senescence remains elusive.

Ageing and the oxidative-inflammatory stress Ageing is accompanied by events that involve chronic sterile low-grade inflammation, a phenomenon named as inflammageing by Franceschi et al. in 2006 (Ref. 61). Inflammageing has its founda-tion in the observation that organisms are under sustained expos-
