Research Mechanism Summary
Oxytocin is a 9-residue cyclic disulfide-bridged neuropeptide (Cys1-Tyr-Ile-Gln-Asn-Cys6-Pro-Leu-Gly-NH2, with a Cys1–Cys6 disulfide bridge) produced in hypothalamic paraventricular and supraoptic nuclei; it signals via OXT receptors (OXTRs) — GPCRs broadly expressed in the brain, uterus, and peripheral tissue — activating intracellular Ca2+ and PKC cascades (https://pubmed.ncbi.nlm.nih.gov/1319071/). Research has characterized its role as a regulator of social bonding, pair bond formation, and affiliative behavior through OXTR-mediated modulation of mesolimbic dopamine circuits, while peripheral OXT influences uterine contractility, milk ejection, and pain modulation via trigeminal ganglia OXTR expression (https://pubmed.ncbi.nlm.nih.gov/32486908/). Oxytocin is a widely used research reference peptide in neuroscience, reproductive physiology, and social behavior studies.
