Neuropeptide

Overview

Oxytocin is classified as a neuropeptide peptide. Social bonding, anxiety reduction, gut motility, anti-inflammation, libido, trust and empathy.

Nonapeptide produced in the hypothalamus and released by the posterior pituitary. Binds oxytocin receptors (OXTR) broadly expressed in brain, heart, gut, and immune cells. Modulates HPA axis stress response, reduces cortisol, promotes prosocial behavior, accelerates GI motility, and exerts anti-inflammatory effects via NF-kB inhibition. Intranasal administration crosses blood-brain barrier to produce central effects.

Also known as: OXT, Pitocin (IV form), Syntocinon

How Does Oxytocin Work?

Nonapeptide produced in the hypothalamus and released by the posterior pituitary. Binds oxytocin receptors (OXTR) broadly expressed in brain, heart, gut, and immune cells. Modulates HPA axis stress response, reduces cortisol, promotes prosocial behavior, accelerates GI motility, and exerts anti-inflammatory effects via NF-kB inhibition. Intranasal administration crosses blood-brain barrier to produce central effects.

At the molecular level, Oxytocin operates through pathways characteristic of the Neuropeptide class, interacting with target receptors and downstream signaling cascades to produce its observed effects.
