Roleofoxytocinin the protective function of the cardiovascular system

Abstract

Oxytocin is synthesized in endothelial cells of the cardiovascular system and exerts its effects by oxytocin receptors. The effect of oxytocin on vascular tone, blood pressure, vascular growth and remodeling, as well as participation in cardiovascular regulation has been proven. The positive effect of oxytocin on infarct size and recovery of contractile function in reperfusion is well studied. It should be noted that the mechanisms of this cardioprotective effect have not yet been studied. Research evidence suggests that oxytocin therapy significantly improves cardiac function, reduces inflammation and apoptosis, and improves scar vascularization. Oxytocin stimulates the transformation of stem cells into clones of cardiomyocytes. Oxytocin promotes angiogenesis by stimulating the formation of endothelial and smooth muscle cells. Increased consumption of glucose by cardiomyocytes, inhibition of cardiomyocyte hypertrophy, and a decrease in oxidative stress are the reasons for the positive effects of oxytocin. Oxytocin reduces inflammation, improves cardiovascular and metabolic function. This is the manifestation of the cardioprotective effect of oxytocin. Potential treatment of cardiovascular diseases with oxytocin is possible due to the pleiotropic nature of oxytocin effects. This review indicates the likely mechanisms of oxytocin action at the cellular level that are involved in cardioprotection.
