Oxytocin and Estrogen Receptor β in the Brain: An Overview

open access: yesFrontiers in Endocrinology, 2015
Oxytocin is a neuropeptide synthesized primarily by neurons of the paraventricular and supraoptic nuclei of the hypothalamus. These neurons have axons that project into the posterior pituitary and release oxytocin into the bloodstream to promote labor ...

Oxytocin and social pretreatment have similar effects on processing of negative emotional faces in healthy adult males [PDF]

open access: yes, 2013
Oxytocin has been shown to affect several aspects of human social cognition, including facial emotion processing. There is also evidence that social stimuli (such as eye-contact) can effectively modulate endogenous oxytocin levels.

Characterization and Expression of Oxytocin and the Oxytocin Receptor

open access: yesMolecular Genetics and Metabolism, 2000
Oxytocin, a nonapeptide hormone and neurotransmitter, is expressed in a variety of tissues, as are its receptors. In vivo, oxytocin acts as a paracrine and/or autocrine mediator of multiple biological effects. These effects are exerted primarily through interactions with G-protein-coupled oxytocin/vasopressin receptors, which, via G(q) and G(i ...

Oxytocin levels tend to be lower in autistic children: A meta-analysis of 31 studies

open access: yesAutism, 2021
The oxytocin system may be different in autistic people, which could explain some of the deficits in social behavior and cognition associated with autism spectrum disorder.

Elevated salivary levels of oxytocin persist more than seven hours after intranasal administration

open access: yesFrontiers in Neuroscience, 2012
We addressed the question how long salivary oxytocin levels remain elevated after intranasal administration, and whether it makes a difference when 16 IU or 24 IU of oxytocin administration is used.

Immunoglobulin G is a natural oxytocin carrier which modulates oxytocin receptor signaling: relevance to aggressive behavior in humans

open access: yesDiscover Mental Health, 2023
Oxytocin is a neuropeptide produced mainly in the hypothalamus and secreted in the CNS and blood. In the brain, it plays a major role in promoting social interactions.

Oxytocin-dependent reopening of a social reward learning critical period with MDMA

open access: yesNature, 2019
A critical period is a developmental epoch during which the nervous system is expressly sensitive to specific environmental stimuli that are required for proper circuit organization and learning.

The Effects of Oxytocin on Appetite Regulation, Food Intake and Metabolism in Humans

open access: yesInternational Journal of Molecular Sciences, 2021
The hypothalamic peptide oxytocin and its receptor are involved in a range of physiological processes, including parturition, lactation, cell growth, wound healing, and social behavior.

Inter-institutional variations in oxytocin augmentation during labour in German university hospitals : a national survey [PDF]

open access: yes, 2019
There are several international guidelines on oxytocin regimens for induction and augmentation of labour, but no agreement on a standardised regimen in Germany.

Increased Serum and Urinary Oxytocin Concentrations after Nasal Administration in Beagle Dogs

open access: yesFrontiers in Veterinary Science, 2017
In recent years more and more studies have revealed the effect of extraneous oxytocin on the social behavior of dogs. The distribution of administered oxytocin in different physiologically relevant compartments is important because this knowledge forms ...
