Oxytocin is a neuropeptide secreted by the brain, and it has been hypothesized to be a part of the processes of bonding, reproduction, gestation, and delivery.
Oxytocin is a protein hormone, and research suggests it may have two natural functions. Researchers propose that Oxytocin is a hormone that may circulate in the blood and is produced by the placenta of pregnant females.
It has been purported to have a potentially integral role in the process of birth, as well as in the production of breast milk and the emotional attachment of newborns to mothers.
Scientists theorise that Oxytocin is produced in the testes and may have a role in both the behaviour of pairing-off and the bonding that occurs between species.
Oxytocin is a peptide hormone of nine amino acids released by the posterior pituitary gland. Oxytocin is a precursor molecule when it is in its natural condition.
This molecule must undergo a split to become the active hormone. Research has suggested that the peptide may be generated in the thymus, adrenal glands, pancreas, and retina.
Oxytocin is often thought of as a neurohypophysial hormone; however, research has proposed that it may also have functions in different tissues throughout the organism.
Oxytocin Peptide and Tissue Damage
Studies suggest the peptide may affect the severity of inflammation because it may act on inflammatory cytokines.
In a study involving 37 different research model pairs and their wound healing, scientists proposed that social interaction appeared to increase the level of the hormone Oxytocin, which seemingly sped up the healing process.
In addition, novel research was carried out on research subject pairs to investigate the possible impact of hostility in social interactions on the healing process.
On the other hand, pairs who had poor social ties appeared to have a wound healing rate that was about 40%. At the location of the injury, these pairs also seemed to have lower quantities of IL-6, tumour necrosis factor-alpha, and IL-1 beta.
Oxytocin Peptide and the Cardiovascular System
Oxytocin has been suggested to hasten the healing of wounds and to have a possible impact on inflammatory cytokines. As a result, many research professionals hypothesize that it may assist in protecting the cardiovascular system.
Preliminary investigations suggest the peptide may protect the heart and circulatory system by reducing fat mass, lowering blood pressure, improving glucose tolerance, and reducing the levels of stress hormone secretion.
Data from science suggests that inhibiting Oxytocin receptors may contribute to the development of atherosclerosis in some circumstances.
In exceptional cases, elevating Oxytocin levels cases of low receptor density may support the maintenance of cardiovascular integrity and even reverse the progression of atherosclerosis.
Studies have purported that it is possible to prevent damage or death to cardiomyocytes caused by ischemia by presenting the substance directly into the heart at the time of the condition.
Research conducted by Jankoski and colleagues suggests that increasing the concentration of Oxytocin may reduce the risk of developing dilated cardiomyopathy in the long run.
It is proposed to help prime cardiac stem cells so that they are more able to assist in “tissue rejuvenation via differentiation, secretion of cardiomyogenic and protective factors, and aid their fusion with injured cardiomyocytes.”
In trials conducted on animals, the peptide was speculated to protect the heart from the damage caused by diabetes. The peptide appeared to reduce the production of fat cells by roughly 19% and reduce the levels of fasting glucose by approximately 23%. These are the results that may be expected when insulin resistance is reduced.
The under-study mouse models seemed to exhibit much less systolic and diastolic dysfunction than the controls, leading to significantly less cardiomyocyte hypertrophy, apoptosis, and fibrosis.
Investigations purport the peptide may prevent ischemia from occurring in other tissues. In rat models of priapism (persistent erection), presentation with Oxytocin was theorized to reduce levels of nitric oxide, which in turn may protect against the damage caused by ischemia and reperfusion.
Oxytocin Peptide and Cognition
Oxytocin has been suggested to increase hormone levels in the prefrontal cortex of mice deprived of their mothers. These hormone levels are associated with neuron formation.
Findings implied that following the presentation with Oxytocin, there seemed to be an improvement in the group’s cognitive ability; nevertheless, there were no general changes in the research models’ behaviours.
In other research studies employing mice, it was proposed that Oxytocin may have led to an increase in learning in a manner that was not statistically significant when the mice were placed in stressful environments.
Oxytocin Peptide and Stress Hormone Release
In a study of research models of social issues, epigenetic modifications in the hormone Oxytocin were speculated, suggesting that a reduction in the signalling potential of Oxytocin may cause social anxiety.
The dysregulation of Oxytocin levels has recently been related to Borderline Personality Disorder (also known as BPD), as purported by recent studies.
In research models of BPD, there is an abnormally high level of mistrust, a heightened awareness of potential threats, and altered nonverbal social interaction. The Oxytocin peptide was introduced into research models of BPD and was suggested to affect several of these behavioural traits.
