Description
Oxytocin 5 mg — Neuropeptide Hormone for Social, Stress & CNS Research
Oxytocin is a cyclic nonapeptide hormone produced primarily in the
hypothalamus and released from the posterior pituitary. Beyond its classical roles in
parturition and lactation, oxytocin has become a major focus of research in
social behavior, stress regulation, bonding, and affective neuroscience.
What It Is
- Class: Endogenous peptide hormone / neuropeptide
- Peptide length: 9 amino acids (cyclic nonapeptide)
- Research focus: Social cognition, stress and anxiety pathways,
autonomic regulation, and neuroendocrine signaling.
Proposed Mechanisms (Preclinical & Translational)
Oxytocin Receptor & CNS Circuits
- Binds to the oxytocin receptor (OXTR), a G protein–coupled receptor
expressed in brain and peripheral tissues. - Investigated in amygdala, prefrontal cortex, nucleus accumbens, and
hypothalamic circuits involved in emotion and social behavior. - Linked to modulation of GABAergic and glutamatergic signaling,
as well as interactions with dopaminergic reward pathways.
Stress, Bonding & Autonomic Regulation
- Studied for effects on stress-axis activity (e.g., HPA axis,
cortisol readouts) in experimental models. - Central role in bonding, affiliation, and maternal behaviors
in animal and human research. - Explored for changes in heart-rate variability, blood pressure,
and autonomic balance in psychophysiologic studies.
Selected Research Highlights
- Social & Affective Neuroscience: Oxytocin is widely used to study
trust, social recognition, bonding, and emotional processing in controlled
paradigms. - Anxiety & Stress Models: Experimental work examines behavioral
and endocrine responses to acute and chronic stress with oxytocin
modulation. - Neurodevelopmental & Psychiatric Contexts: Used as a probe in
research on social-communication and affective disorders, with focus on
mechanistic endpoints rather than approved treatment claims.
