Oxytocin (OXT) is a neuropeptide that plays a pivotal role among species peripherally and centrally. It recently has attracted much attention for its involvement in anxiety-related behavior, stress regulation, social behavior and various neuropsychiatric disorders. OXT is one of the important mediators of emotional and social behaviors such as maternal behavior, fear extinction, social support, happiness, and trust. It is also involved in learning and memory process. The recent progresses in OXT system have put this neuropeptide as an important psychotherapeutic intervention for various psychiatric disorders such as stress, anxiety disorders, social phobia, postpartum depression, bipolar disorder, autism, and schizophrenia...

BACKGROUND: This study investigated the associations of maternal oxytocin, self-reported attachment insecurity and depressive symptoms with maternal caregiving sensitivity at 3-4months postpartum, observed during the 'free play' and 'reunion' episodes of the Still Face Procedure. METHODS: 112 mothers completed questionnaires and gave blood samples to determine oxytocin plasma levels before (time 1) and after participating in the Still Face Procedure with their infant (time 2)...

The influence of sex on prevalence and presentation of human depression necessitates studying its role in depression. Additionally, stress can also affect the incidence and progression of depressive phenotypes. Hypothalamus is a well-reported sexually dimorphic brain region. Hence, we performed a gene-array to uncover the chronic stress-induced transcriptional changes in the hypothalamus of male, intact female (with ovaries) and ovariectomized female mice. Chronic variable mild stress model was used to induce depression-like behavior in mice, assessed by despair behavior in forced swim test...

Opioid addiction has devastating health and socio-economic consequences, and current pharmacotherapy is limited and often accompanied by side effects, thus novel treatment is warranted. Traditionally, the neurohypophyseal peptide oxytocin (OT) is known for its effects on mediating reward, social affiliation and bonding, stress and learning and memory. There is now strong evidence that OT is a possible candidate for the treatment of drug addiction and depression-addiction co-morbidities. This review summarizes and critically discusses the preclinical evidence surrounding the consequences of pharmacological manipulation of the oxytocinergic system on opioid addiction-related processes, as well as the effects of opioids on the OT system at different stages of the addiction cycle...

Social isolation is a known stressor that negatively impacts the well-being of social species. In rodents, social deprivation experienced either before or after weaning profoundly impacts adult behavioral and neuroendocrine profiles. This study compared the effects of post-natal and post-weaning social deprivation on behavioral profiles and hypothalamic oxytocin (OT) neurons. Male and female Sprague-Dawley rats were assigned to two post-natal groups, maternally separated (MS) or non-MS. MS pups were separated from their mothers for 4h daily during post-natal days 2-21 while non-MS litters remained undisturbed...

BACKGROUND: The oxytocin receptor (OXTR) gene may be involved in resilience or vulnerability towards stress, and hence in the development of stress-related disorders. There are indications that OXTR single nucleotide polymorphisms (SNPs) interact with early life stressors in predicting levels of depression and anxiety. To replicate and extend these findings, we examined whether three literature-based OXTR SNPs (rs2254298, rs53576, rs2268498) interact with childhood maltreatment in the development of clinically diagnosed depression and anxiety disorders...

The introduction of allosteric receptor-receptor interactions in G protein-coupled receptor (GPCR) heteroreceptor complexes of the central nervous system (CNS) gave a new dimension to brain integration and neuropsychopharmacology. The molecular basis of learning and memory was proposed to be based on the reorganization of the homo- and heteroreceptor complexes in the postjunctional membrane of synapses. Long-term memory may be created by the transformation of parts of the heteroreceptor complexes into unique transcription factors which can lead to the formation of specific adapter proteins...

Mother-infant contact has a critical role on brain development and behavior. Experiencing early-life adversities (such as maternal separation stress or MS in rodents) results in adaptations of neurotransmission systems, which may subsequently increase the risk of depression symptoms later in life. In this study, we show that Oxytocin (OT) exerted antioxidant and anti-inflammatory properties. Previous studies indicate that neuroinflammation and mitochondrial dysfunction are associated with the pathophysiology of depression...

Research in humans and nonhuman animals indicates that social affiliation, and particularly maternal bonding, depends on reward circuitry. Although numerous mechanistic studies in rodents demonstrated that maternal bonding depends on striatal dopamine transmission, the neurochemistry supporting maternal behavior in humans has not been described so far. In this study, we tested the role of central dopamine in human bonding. We applied a combined functional MRI-PET scanner to simultaneously probe mothers' dopamine responses to their infants and the connectivity between the nucleus accumbens (NAcc), the amygdala, and the medial prefrontal cortex (mPFC), which form an intrinsic network (referred to as the "medial amygdala network") that supports social functioning...

This study investigates paternal brain function with the hope of better understanding the neural basis for variation in caregiving involvement among men. The neuropeptides oxytocin (OT) and vasopressin (AVP) are implicated in paternal caregiving in humans and other species. In a double-blind, placebo-controlled, within-subject pharmaco-functional MRI experiment, we randomized 30 fathers of 1-2year old children to receive either 24IU intranasal OT before one scan and placebo before the other scan (n=15) or 20IU intranasal AVP before one scan and placebo before the other scan (n=15)...

The hypothalamic neuropeptide oxytocin (OT) has received increasing attention for its role in modulating social-emotional processes across species. Previous studies on using intranasal-OT in humans point to a crucial engagement of the amygdala in the observed neuromodulatory effects of OT under task and rest conditions. However, the amygdala is not a single homogenous structure, but rather a set of structurally and functionally heterogeneous nuclei that show distinct patterns of connectivity with limbic and frontal emotion-processing regions...

BACKGROUND: Due to its potent effects on social behavior, including maternal behavior, oxytocin has been identified as a potential mediator of postpartum depression and anxiety. The objective of this study was to examine the relationship between peripartum synthetic oxytocin administration and the development of depressive and anxiety disorders within the first year postpartum. We hypothesized that women exposed to peripartum synthetic oxytocin would have a reduced risk of postpartum depressive and anxiety disorders compared with those without any exposure...

OBJECTIVES: The current study sought to characterize changes in salivary oxytocin (OT) secretion patterns across the breastfeeding cycle, and to evaluate whether breastfeeding has a positive effect on mood disturbances related to postpartum depression, via endogenous OT release. MATERIALS AND METHODS: Twenty-four primiparous mothers who delivered vaginally at term and were exclusively breastfeeding were examined 4-5 days postpartum. Salivary OT was measured using enzyme immunoassays at 30 minutes before breastfeeding (baseline), during breastfeeding (feeding), and 30 minutes after completing breastfeeding (postfeeding)...

OBJECTIVE: Anorexia nervosa (AN), a psychiatric disorder characterized by restriction of food intake despite severe weight loss, is associated with increased comorbid anxiety and depression. Secretion of oxytocin, an appetite-regulating neurohormone with anxiolytic and antidepressant properties, is abnormal in AN. The link between oxytocin levels and psychopathology in AN has not been well explored. METHODS: We performed a cross-sectional study of 79 women aged 18-45 years (19 AN, 26 AN in partial recovery [ANPR], and 34 healthy controls [HC]) investigating the relationship between basal oxytocin levels and disordered eating psychopathology, anxiety, and depressive symptoms...

BACKGROUND: Neuroendocrine biomarkers have long been studied in the context of electroconvulsive therapy (ECT). We prospectively assessed serum oxytocin change and moderators thereof in an exploratory study of patients receiving ECT. METHODS: Serum oxytocin concentrations were assessed immediately before and 1 to 3 minutes after the first ECT in 33 patients with schizophrenia (n = 14), other nonaffective psychosis (n = 6), mania (n = 10), and depression (n = 3) who received 6 to 7 bitemporal, brief-pulse ECTs...

Pain is a ubiquitously unpleasant feeling among humans as well as many animal species often caused by actual and potential tissue damage. However, it is absolutely crucial for our survival in many ways. Acute pain can signal the presence of danger or life-threatenting events, which help escape noxious stimuli. By contrast, when pain becomes chronic or persistent, it becomes an encumbrance and exerts deleterious effects to the body and mind, often co-occured with anxiety and depression. Additionaly, chronic pain is more or less an economic burden for the patients because it requires immediate medical treatments and seriously hinders pepople in their work...

BACKGROUND: Prelabour rupture of membranes (PROM) at term is managed expectantly or by planned early birth. It is not clear if waiting for birth to occur spontaneously is better than intervening, e.g. by inducing labour. OBJECTIVES: The objective of this review is to assess the effects of planned early birth (immediate intervention or intervention within 24 hours) when compared with expectant management (no planned intervention within 24 hours) for women with term PROM on maternal, fetal and neonatal outcomes...

Severe stress in early life, such as childhood abuse and neglect, constitutes a major risk factor in the etiology of psychiatric disorders and somatic diseases. Importantly, these long-term effects may impact the next generation. The intergenerational transmission of maternal early life stress (ELS) may occur via pre-and postnatal pathways, such as alterations in maternal-fetal-placental stress physiology, maternal depression during pregnancy and postpartum, as well as impaired mother-offspring interactions...

Women have a lifetime risk of major depression double that of men but only during their reproductive years. This sex difference has been attributed partially to activational effects of female sex steroids and also to the burdens of pregnancy, childbirth, and parenting. Men, in contrast, have a reproductive period difficult to delineate, and research on the mental health of men has rarely considered the effects of fatherhood. However, the couple goes through a number of potentially stressing events during the reproductive period, and both mothers and fathers are at risk of developing peripartum depression...

The highly-interconnected and neurochemically-rich frontal cortex plays a crucial role in the regulation of mood and cognition, domains disrupted in depression and other central nervous system disorders, and it is an important site of action for their therapeutic control. For improving our understanding of the function and dysfunction of the frontal cortex, and for identifying improved treatments, quantification of extracellular pools of neuromodulators by microdialysis in freely-moving rodents has proven indispensable...
