Oxytocin

Oxytocin Endogenous Neuropeptide Neurohormone | Research Use Only

Oxytocin is a naturally occurring cyclic nonapeptide synthesized in the paraventricular and supraoptic nuclei of the hypothalamus and released via the posterior pituitary gland. As one of the most extensively studied neuropeptides in biomedical research, oxytocin plays multifaceted roles in neuroendocrine signaling, peripheral organ function, and central nervous system modulation.

In preclinical and in vitro research, oxytocin has been investigated across a broad range of biological systems. Research applications include studies of hypothalamic-pituitary axis signaling, uterine smooth muscle contractility models, mammary gland biology, and reproductive physiology investigations. Centrally, oxytocin has been extensively utilized in social behavior research models, stress and anxiety response studies, and investigations of amygdala and hippocampal signaling pathways. Additional research areas include cardiovascular biology models, pain modulation studies, anti-inflammatory pathway investigations, and preclinical models examining oxytocin receptor (OXTR) pharmacology and downstream signaling cascades.
