INTRODUCTION: Oxytocin (OT) is a well-known neuropeptides which together with vasopressin, melatonin, insulin and other hormones can alter both behavior and physiological or neuronal functions. This growing interest on OT roles is also based on the demonstrated beneficial effects as a stress reliever and a social bonding agent. The association between old age and OT was only vaguely studied. Little or few is known on the effect of the OT hormone on the old body. Hereby, we present our preliminary results in the research on behavioral changes regarding the intraperitoneal administration of OT in aged rats...

The increasing prevalence of postnatal anxiety highlights the need for summarizing the recent research on this condition to inform screening and intervention efforts. This narrative review of the literature was derived from a search on PubMed and PsycINFO for papers published since 2010. The demographic risk factors for postnatal anxiety include being a young mother, having more education and being employed. Childbirth risk factors include being primiparous in one sample and multiparous in another, caesarean delivery, fear of the birth and of death during delivery, lack of control during labor, low self-confidence for the delivery and the delivery staff, and premature delivery...

Background: Child maltreatment (CM) and attachment experiences are closely linked to alterations in the human oxytocin (OXT) system. However, human data about oxytocin receptor (OXTR) protein levels are lacking. Therefore, we investigated oxytocin receptor (OXTR) protein levels in circulating immune cells and related them to circulating levels of OXT in peripheral blood. We hypothesized reduced OXTR protein levels, associated with both, experiences of CM and an insecure attachment representation. Methods: OXTR protein expressions were analyzed by western blot analyses in peripheral blood mononuclear cells (PBMC) and plasma OXT levels were determined by radioimmunoassay (RIA) in 49 mothers...

BACKGROUND: While maternal depression is known to carry long-term negative consequences for offspring, very few studies followed children longitudinally to address markers of resilience in the context of maternal depression. We focused on oxytocin (OT) and mother-child synchrony - the biological and behavioral arms of the neurobiology of affiliation - as correlates of resilience among children of depressed mothers. METHOD: A community birth-cohort was recruited on the second postbirth day and repeatedly assessed for maternal depression across the first year...

The infant's psycho-physiological regulatory system begins to develop prenatally and continues to mature during the postnatal period. Temperament is a construct comprising tonic individual differences in dispositional physiological and behavioural reactions as well as an evolving ability to regulate to environmental conditions. Theoretical models and research have shown that neurohormonal and -physiological factors contribute to individual development and impact infant behaviours as well as the developing regulatory system...

Although the neurohypophyseal hormones vasopressin and oxytocin are mostly known for their role respectively in antiduresis the former and in labour, lactation and maternal behavior the latter, both might exert widespread influences either on emotion and cognition in healthy subjects, showing some gender-related differences. They interact one each other facilitating shifts between positive socially- oriented and defensive states. In fact, vasopressin amplifies the reactivity to stressors showing also beneficial effects on attention, verbal learning as well as memory, whereas oxytocin reduces the amplitude of the stress response, improves emotion processing, and can play a negative effect on memory and verbal learning in healthy individuals...

The aim of this study was to investigate placental DNA methylation of the oxytocin receptor gene (OXTR) in women with depression in pregnancy. We also explored the role of antidepressant medication in pregnancy on placental OXTR methylation. Data were obtained from 239 women in the Mercy Pregnancy and Emotional Wellbeing Study (MPEWS), a selected pregnancy cohort. Current depressive disorders were diagnosed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID-IV)...

There is increasing recognition that women have a higher prevalence of certain psychiatric illnesses, and a differential treatment response and course of illness compared to men. Additionally, clinicians deal with a number of disorders like premenstrual syndrome, premenstrual dysphoric disorder, and postpartum depression, which affect women specifically and for which treatment and biological pathways are still unclear. In this article we highlight recent research which suggests that different biological mechanisms may underlie sex differences in responsiveness to stress...

BACKGROUND: Childhood and adulthood traumatic experiences negatively impact maternal-infant bonding and increase risk of postpartum depression (PPD). Lower oxytocin levels have also been associated with PPD and compromised mother-infant bonding. Despite advances in these areas of investigation, much of the research has not included Latinas, who are important because they have high rates of fertility, traumatic events, and PPD. METHODS: To address gaps identified in the literature, we explored associations between traumatic life events, PPD, and bonding subscale scores (e...

In humans and rodent animal models, the brain oxytocin system is paramount for facilitating social bonds, from the formation and consequences of early-life parent-infant bonds to adult pair bond relationships. In social species, oxytocin also mediates the positive effects of healthy social bonds on the partners' well-being. However, new evidence suggests that the negative consequences of early neglect or partner loss may be mediated by disruptions in the oxytocin system as well. With a focus on oxytocin and its receptor, we review studies from humans and animal models, i...

Oxytocin (OXT) receptors (OXTRs) are prominently expressed in hippocampal CA2 and CA3 pyramidal neurons, but little is known about its physiological function. As the functional necessity of hippocampal CA2 for social memory processing, we tested whether CA2 OXTRs may contribute to long-term social recognition memory (SRM) formation. Here, we found that conditional deletion of Oxtr from forebrain (Oxtr-/-) or CA2/CA3a-restricted excitatory neurons in adult male mice impaired the persistence of long-term SRM but had no effect on sociability and preference for social novelty...

BACKGROUND: Oxytocin is a peptide hormone that influences the integration of social cognition with behavior and affect regulation. Oxytocin also prominently directs the transition of neuronal GABA neurotransmission from excitatory to inhibitory after birth. The oxytocin receptor (OXTR) is linked to schizophrenia, a heterogeneous syndrome. Relationships of OXTR polymorphisms with specific clinical features could aid in evaluating any role of oxytocin in the pathogenesis of schizophrenia...

Despite the high prevalence of panhypopituitarism and diabetes insipidus in patients with craniopharyngioma (CP), little is known about the functioning of the neuropeptide oxytocin in these patients. This is of special interest as tumor-associated lesions often impair sites critical for oxytocin production and release, and affective dysfunction in CP links with elsewhere reported prosocial, antidepressant and anxiolytic oxytocin effects. Using a prospective study-design, we tested whether oxytocin is reduced in CP-patients, and whether altered oxytocin levels account for affective and emotional dysfunction...

Recent work suggests that key aspects of sensitive parenting (e.g., warmth, emotional attunement) may be shaped in part by biology, specifically the neuropeptide oxytocin. However, some studies have found that oxytocin may not act in expected ways in higher-risk populations (e.g., those with postnatal depression or borderline personality disorder). This study examined the relation between oxytocin and parenting among mothers with varying levels of early life stress. Forty low-income mothers and their 34- to 48-month-old child participated in this study...

The complex bidirectional communication between the gut and the brain is finely orchestrated by different systems, including the endocrine, immune, autonomic, and enteric nervous systems. Moreover, increasing evidence supports the role of the microbiome and microbiota-derived molecules in regulating such interactions; however, the mechanisms underpinning such effects are only beginning to be resolved. Microbiota-gut peptide interactions are poised to be of great significance in the regulation of gut-brain signaling...

Oxytocin receptor gene (OXTR) polymorphisms, lower ventral striatum (VS) response to social stimuli, and lower economic privilege have been independently associated with depression and anxiety. However, the interactions between these risk factors are unknown. One hundred and fifty-seven healthy adult participants genotyped for OXTR rs237915 completed a common emotion-matching task during functional magnetic resonance imaging. Past economic privilege and depression and anxiety symptoms were concurrently assessed through validated self-report measures...

BACKGROUND: Oxytocin is associated with bonding and social deficits in psychiatric disorders and has also been discussed as a potential therapeutic intervention to augment psychotherapy. The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) is a specific form of psychotherapy for chronic depression, an illness in which interpersonal deficits play a major role. In this pilot study, we investigated whether Oxytocin plasma levels predict the clinical outcome of chronic depressive patients after CBASP...

BACKGROUND: Depressed individuals often refuse or withdraw from help, a phenomenon termed help-negation, which is a risk factor for poor outcomes. Most previous research has investigated psychosocial factors including stigma as causes of low help-seeking intentions for depression, however these do not adequately explain the problem. We hypothesised that because help-negation worsens with symptom severity, it might be linked to important biological changes associated with depression itself...

RATIONALE: Possible genetic correlates of spirituality and depression have been identified in community samples. We investigate some of the previously identified candidates in a sample of families at both high and low-risk for depression. METHOD: Offspring and grandchildren of individuals at high and low-risk for depression, participating in a multi-wave thirty-year longitudinal study, were assessed for seven SNPS drawn from four single gene candidates associated with systems implicated in both depression and spirituality: Serotonin (5-HT1B and 5-HT2A), Dopamine (DRD2), Oxytocin (OT) and Monoamine Vesicular Transporter (VMAT1)...
