Abstract

Oxytocin is a neuropeptide produced in the hypothalamus that, in addition  to its classic reproductive functions, plays a relevant role in skeletal muscle  homeostasis. Through the activation of oxytocin receptors (OXTR) present in  muscle fibers and satellite cells, the hormone stimulates cellular pathways  associated with proliferation, myogenic differentiation, and protein synthesis,  favoring muscle regeneration. Oxytocin also exerts a modulating effect on the  inflammatory response, creating suitable physiological conditions for tissue  repair. However, reduced oxytocin levels, especially during aging, are associated with decreased regenerative capacity and the development of muscle atrophy.  Experimental evidence indicates that its action contributes to the balance  between anabolic and catabolic processes, helping to preserve muscle mass and  functionality.
