Antioxidant enzymes and vascular factors

"Antioxidant enzymes and vascular factors" collectively refer to a group of endogenous enzymes such as superoxide dismutase, catalase, glutathione peroxidase, and regulatory vascular factors including nitric oxide synthase, which work together to defend vascular tissues against oxidative stress by neutralizing reactive oxygen and nitrogen species. These enzymes represent the primary line of antioxidant defense and play essential roles in maintaining endothelial health, regulating vascular tone, preventing atherosclerosis, and mitigating inflammatory damage in the cardiovascular system. Altered expression or function of these enzymes is implicated in multiple vascular diseases and is a focus for biomarker and therapeutic research[1][2][3][5].
