Description

Oxytocin is a naturally occurring cyclic nonapeptide hormone synthesized in the hypothalamus and secreted by the posterior pituitary.
It functions as both a neuropeptide and hormone, playing a central role in social bonding, reproductive physiology, stress regulation, and homeostatic control of emotional and behavioral responses.

In research, Oxytocin is extensively studied for its influence on:

• Social cognition and affiliative behavior (trust, empathy, bonding)

• Anxiolytic and stress-attenuating effects via HPA-axis modulation

• Reproductive signaling, including uterine contraction and milk ejection

• Neuroplastic and mood-regulating pathways through interaction with oxytocin and vasopressin receptors (OXTR, AVPR1A/B)

Recent preclinical data suggest that Oxytocin may also interact with dopaminergic reward systems, autonomic control circuits, and immune regulation, making it a key molecule for studying neuroendocrine integration and social behavior mechanisms.
