Research record
Overview
Compound name: Oxytocin
Common abbreviation: OXT
Compound classification: Endogenous neuropeptide hormone
Brief factual description:
Oxytocin is a naturally occurring peptide hormone and neuropeptide produced in the hypothalamus and released by the posterior pituitary. It plays a central role in social bonding, reproduction, childbirth, lactation, and modulation of stress and emotional behavior.
Mechanism of Action
Primary biological targets: Oxytocin receptor (OXTR)
Affected systems: Neuroendocrine, reproductive, cardiovascular, central nervous system
Receptor selectivity:
High affinity for OXTR (G-protein–coupled receptor)
Downstream signaling effects:
Activation of phospholipase C (PLC) pathway
Increased intracellular calcium signaling
Modulation of neuronal excitability and synaptic plasticity
