Brain region-specific roles of brain-derived neurotrophic factor in social stress-induced depressive-like behavior

Brain-derived neurotrophic factor is a key factor in stress adaptation and avoidance of a social stress behavioral response.Recent studies have shown that brain-derived neurotrophic factor expression in stressed mice is brain region–specific,particularly involving the corticolimbic system,including the ventral tegmental area,nucleus accumbens,prefrontal cortex,amygdala,and hippocampus.Determining how brain-derived neurotrophic factor participates in stress processing in different brain regions will deepen our understanding of social stress psychopathology.In this review,we discuss the expression and regulation of brain-derived neurotrophic factor in stress-sensitive brain regions closely related to the pathophysiology of depression.We focused on associated molecular pathways and neural circuits,with special attention to the brain-derived neurotrophic factor–tropomyosin receptor kinase B signaling pathway and the ventral tegmental area–nucleus accumbens dopamine circuit.We determined that stress-induced alterations in brain-derived neurotrophic factor levels are likely related to the nature,severity,and duration of stress,especially in the above-mentioned brain regions of the corticolimbic system.Therefore,BDNF might be a biological indicator regulating stress-related processes in various brain regions.

Female zebra finches are more vulnerable to social isolation stress than males:Involvement of the nonapeptide system

In group-living animals,chronic juvenile social isolation stress(SIS)can profoundly affect behavior and neuroendocrine regulation.However,its impact on social behavior in avian species,particularly regarding sexspecific neural circuit differences,remains underexplored.This study focused on zebra finches,a species known for its social clustering and cognitive abilities,to elucidate these influences.Results indicated that SIS significantly increased plasma corticosterone levels in females but not in males,suggesting a heightened stress response and susceptibility in females.Additionally,SIS disrupted sociality and flocking behavior in both sexes,with more severe impairments in social recognition observed in females.Mesotocin(MT)levels in the lateral septum of both sexes and in the ventromedial hypothalamus of females were found to mediate the SIS effect,while vasotocin(VT)levels within the social behavior network remained unchanged.Pharmacological interventions confirmed the critical role of MT in reversing SIS-induced impairments in sociality,flocking behavior,and social recognition,particularly in females.These findings highlight unique nucleus-and sex-dependent variations in MT and VT regulation,providing novel insights into the mechanisms governing avian social behavior.This study advances our understanding of the independent evolutionary pathways of neural circuits and neuroendocrine systems that modulate social behaviors across different taxonomic groups.

Density-induced social stress alters oxytocin and vasopressin activities in the brain of a small rodent species

It is known that social stress could alter oxytocin(OT)and arginine-vasopressin(AVP)expression in specific regions of brains which regulate the aggressive behavior of small rodents,but the effects of density-induced social stress are still unknown.Brandt’s voles(Lasiopodomys brandtii)are small herbivores in the grassland of China,but the underlying neurological mechanism of population regulation is still unknown.We tested the effects of housing density of Brandt’s voles on OT/AVP system with physical contact(allowing aggression)and without physical contact(not allowing aggression)under laboratory conditions.Then,we tested the effects of paired-aggression(no density effect)of Brandt’s voles on OT/AVP system under laboratory conditions.We hypothesized that high density would increase aggression among animals which would then increase AVP but reduce OT in brains of animals.Our results showed that high housing density induced more aggressive behavior.We found high-densityinduced social stress(with or without physical contact)and direct aggression significantly increased expression of mRNA and protein of AVP and its receptor,but decreased expression of mRNA and protein of OT and its receptor in specific brain regions of voles.The results suggest that density-dependent change of OT/AVP systems may play a significant role in the population regulation of small rodents by altering density-dependent aggressive behavior.

Ginsenoside Rb1 produces antidepressant-like effects in chronic social defeat stress model of depression through BDNF-TrkB sig⁃naling pathway

OBJECTIVE Ginsenoside Rb1(Rb1),an important bioactive ingredient of Panax ginseng,has potent neuroprotective effects.The objective of the study is to elucidate the impact of Rb1 treatment on chronic social defeat stress(CSDS)-induced depressive-like behaviors and its related mechanism.METHODS AND RE⁃SULTS The daily oral administration of Rb1(35 and 70 mg·kg-1)and imipramine(15 mg·kg-1)for 28 d significantly reversed the social avoidance behavior,anhedonia,and behavioral despair via CSDS exposure,as demonstrated by the consid⁃erable elevation in the time in the zone in social interaction test and consumption of sucrose solu⁃tion in sucrose preference test and decrease of immobility time in forced swim test.Moreover,Rb1 obviously restored the CSDS-induced decrease of BDNF-signaling pathway and hippo⁃campal neurogenesis.Rb1 significantly increased the hippocampal levels of ERK,AKT,and CREB phosphorylation and increased the number of DCX+cells in DG.Importantly,the antidepres⁃sant effects of Rb1 were completely blocked in mice by using K252a(the nonselective tyrosine kinase B inhibitor).CONCLUSION Rb1 exerts promising antidepressant-like effects in mice with CSDS-induced depression,and its effects was facilitated by enhancing the BDNF signaling cas⁃cade and up-regulation of hippocampal neuro⁃genesis.

Relationship between acute stress and sleep disorder in grass-root military personnel:Mediating effect of social support

Background: To explore the relationship between acute stress, social support and sleep disorder in grass-root military personnel, and construct the relational model through structural equation modeling. Methods: A total of 2,411 grass-root military personnel were randomly selected by cluster sampling, and administered the Chinese Military Personnel Sleep Disorder Scale, Military Acute Stress Scale and Social Support Rating Scale.Results: The total score of acute stress scale was positively correlated with the total score and factor scores of sleep disorder scale(r=0.209~0.465, P【0.01); The total score of social support scale was positively correlated with the total score of acute stress scale and the total score and factor scores of sleep disorder scale(r=0.356~0.537, P【0.01). The analysis of mediating effects showed that lack of social support partially mediated between acute stress and the factors of sleep disorder. The analysis of structural equation model showed that acute stress not only had a direct effect on sleep disorder(the path coefficient was 0.29, P=0.000), but also on lack of social support(the path coefficient was 0.39, P=0.000); lack of social support had a direct effect on sleep disorder(the path coefficient was 0.48, P=0.000).Conclusions: Acute stress and lack of social support are two significant factors of sleep disorder in grass-root military personnel. Well-established social support could alleviate sleep disorder induced by acute stress. Lack of social support was a partial mediator between acute stress and sleep disorder.

Impact of social isolation and resident intruder stress on aggressive behavior in the male rat

Stress studies frequently utilize physical stressors to establish animal models of stress. In the majority of cases, these models are not consistent with human circumstances. The present study simulated a social isolation plus resident intruder stress model in the rat. The rats were subjected to daily social isolation and resident intruder stress for 2 weeks. Behaviors were then tested. Rats subjected to social stress exhibited different aggressive behavior styles; some rats had greater scores on composite aggression behaviors, as well as locomotor and exploratory activity, but lower scores on latency than others. The high-aggressive group exhibited predominantly anger-out, while the low-aggressive group exhibited anger-in. Results suggest that social isolation plus resident intruder may serve as an appropriate model for anger-in and anger-out emotion modeling in the rat.

Effects of Academic Stress and Perceived Social Support on the Psychological Wellbeing of Adolescents in Ghana

The purpose of this study was to examine how academic stress and perceived social support influence the psychological wellbeing of Senior High School students in Ghana. Two hundred and twenty six male and female students participated. The general health questionnaire, student life-stress inventory and perceived social support from family and friends scales were used to assess psychological wellbeing, academic stress and perceived social support respectively. The results indicated that perceived social support buffered the effects of academic stress on psychological wellbeing. Girls reported higher scores on perceived social support but reported more depression. Boys reported higher academic stress and better psychological wellbeing, and these have been attributed partly to the socialisation role of gender. These results have policy implications in respect of the creation of a cordial school environment as well as encouraging a healthy interpersonal relationship between adolescents and their family and friends with the aim of reducing academic stress appraisal which is inimical to the psychological wellbeing of adolescents.

Pathogenesis of chronic social defeat stress model induced depressive-like mouse model according to LC-MS/MS-based metabolomics

OBJECTIVE To explore the pathogenesis of depression according to the LC-MS/MS-based metabolomics in the mouse model which exhibits social avoidance state induced by the chronic social defeat stress model(CSDS).METHODS Twenty male C57BL/6N mice were randomly divided into control group and model group suffering CSDS,and the ICR retired breeder mice were used to attack the model group for 14 d of chronic social defeated stress.The open field test and source preference test were both used to observe depression-like behavior.Besides,the social interaction test is used to observe the social interaction state,especially.After the stress,the serum samples of mice were collected,and the changes of endogenous metabolites were analyzed by LC-MS metabolomics technology,and the pathway analysis of the differential metabolites was performed to explore the pathogenesis of the CSDS induced depressive-like mouse model.RESULTS After the stress of CSDS was completed,the mice in the model group showed a significant slowdown in body weight growth,a reduction in the source preference rate,and a significant reduction in the total distance and the number of rearing in the open field test.Distinctively,the social interaction rate is remarkably decreasing.There are 24 differential metabolites found in the serum of CSDS model mice.CONCLUSION The mouse who suffered CSDS stress would show depressive-like behavior.Based on the LC-MS/MS metabolomics,24 differential metabolites were found in the serum of CSDS model mice.The amino acid metabolism might be significant to the pathogenesis of the CSDS induced depressive-like mouse model.

Pig Social Status and Chronic Cold or Crowd Stressors Differentially Impacted Immune Response

The objectives of this study were to determine the effects of 4-day of cold and crowding stressors and social status on pig immune responsiveness to these stressors. Three unfamiliar white crossbred female pigs were mixed and assigned to ambient temperatures of either 8°C (COLD) or 22°C (control;TN) and floor-space of either 0.26 m2/pig (reduced, CROWD) or 0.45 m2/pig (adequate, CONT) over six blocks (n = 72). Pigs were identified as dominant (DOM), intermediate (INT), or submissive (SUB) based on aggressive encounters that occurred during the first 24-h post-mixing. There were no interactive effects of temperature × floor-space on immune indices. There was social status × stressor for body weight, natural killer (NK) cell cytotoxicity and phagocytosis (P < 0.05). DOM pigs that were COLD or CROWD gained the least amount of body weight compared to either INT or SUB pigs (P < 0.01). INT and SUB pigs subjected to CROWD stress gained more weight compared to their counterparts subjected to COLD temperature or CONT floor-space (P < 0.05). NK cytotoxicity was greater among CROWD-INT pigs and phagocytosis was greater among COLD- and CROWD-SUB pigs. Also, INT pigs had lower T and B cell proliferation regardless of the stressor. COLD stress significantly reduced NK cytotoxicity, total Immunoglobulin-G, and B-cell proliferation and enhanced total WBC counts and T-cell proliferation. These data imply that various immune indices were either enhanced or suppressed by COLD stress, but concurrent exposure to CROWD stressor did not exacerbate these effects. Moreover, social status played a role in determining a pig’s immune responsiveness as it modulated differential homeostatic stress response as the pig attempted to cope with stress.

Path analysis of relationship among personality, perceived stress, coping, social support, and psychological outcomes

AIM: To provide a structural model of the relationship between personality traits, perceived stress, coping strategies, social support, and psychological outcomes in the general population.METHODS: This is a cross sectional study in which the study group was selected using multistage cluster and convenience sampling among a population of 4 million. For data collection, a total of 4763 individuals were asked to complete a questionnaire on demographics, personality traits, life events, coping with stress, social support, and psychological outcomes such as anxiety and depression. To evaluate the comprehensive relation-ship between the variables, a path model was fitted.RESULTS: The standard electronic modules showed that personality traits and perceived stress are important determinants of psychological outcomes. Social support and coping strategies were demonstrated to reduce the increasing cumulative positive effects of neuroticism and perceived stress on the psychological outcomes and enhance the protective effect of extraversion through decreasing the positive effect of perceived stress on the psychological outcomes. CONCLUSION: Personal resources play an important role in reduction and prevention of anxiety and depression. In order to improve the psychological health, it is necessary to train and reinforce the adaptive coping strategies and social support, and thus, to moderate negative personality traits.

Stress-relevant social behaviors of middle-class male cynomolgus monkeys （Macaca fascicularis）

Stress from dominance ranks in human societies, or that of other social animals, especially nonhuman primates, can have negative influences on health. Individuals holding different social status may be burdened with various stress levels. The middle class experiences a special stress situation within the dominance hierarchy due to its position between the higher and lower classes. Behaviorally, questions about where middle-class stress comes from and how individuals adapt to middle-class stress remain poorly understood in nonhuman primates. In the present study, social interactions, including aggression, avoidance, grooming and mounting behaviors, between beta males, as well as among group members holding higher or lower social status, were analyzed in captive male-only cynomolgus monkey groups. We found that aggressive tension from the higher hierarchy members was the main origin of stress for middle- class individuals. However, behaviors such as attacking lower hierarchy members immediately after being the recipient of aggression, as well as increased avoidance, grooming and mounting toward both higher and lower hierarchy members helped alleviate middle-class stress and were particular adaptations to middle-class social status.

Psychosocial mechanisms for the transmission of somatic symptoms from parents to children

AIM: To examine familial aggregation of irritable bowel syndrome(IBS) via parental reinforcement/modeling of symptoms, coping, psychological distress, and exposure to stress.METHODS:Mothers of children between the ages of8 and 15 years with and without IBS were identified through the Group Health Cooperative of Puget Sound.Mothers completed questionnaires,including the Child Behavior Checklist(child psychological distress),the Family Inventory of Life Events(family exposure to stress),SCL-90R(mother psychological distress),and the Pain Response Inventory(beliefs about pain).Children were interviewed separately from their parents and completed the Pain Beliefs Questionnaire(beliefs about pain),Pain Response Inventory(coping)and Child Symptom Checklist[gastrointestinal(GI)symptoms].In addition,health care utilization data was obtained from the automated database of Group Health Cooperative.Mothers with IBS(n=207)and their 296 children were compared to 240 control mothers and their 335 children,while controlling for age and education.RESULTS:Hypothesis 1:reinforcement of expression of GI problems is only related to GI symptoms,but not others(cold symptoms)in children.There was no significant correlation between parental reinforcement of symptoms and child expression of GI or other symptoms.Hypothesis 2:modeling of GI symptomsis related to GI but not non-GI symptom reporting in children.Children of parents with IBS reported more non-GI(8.97 vs 6.70,P<0.01)as well as more GI(3.24 vs 2.27,P<0.01)symptoms.Total health care visits made by the mother correlated with visits made by the child(rho=0.35,P<0.001 for cases,rho=0.26,P<0.001 for controls).Hypothesis 3:children learn to share the methods of coping with illness that their mothers exhibit.Methods used by children to cope with stomachaches differed from methods used by their mothers.Only 2/16 scales showed weak but significant correlations(stoicism rho=0.13,P<0.05;acceptance rho=0.13,P<0.05).Hypothesis 4:mothers and children share psychological traits such as anxiety,depression,and somatization.Child psychological distress correlated with mother’s psychological distress(rho=0.41,P<0.001 for cases,rho=0.38,P<0.001 for controls).Hypothesis 5:stress that affects the whole family might explain the similarities between mothers and their children.Family exposure to stress was not a significant predictor of children’s symptom reports.Hypothesis 6:the intergenerational transmission of GI illness behavior may be due to multiple mechanisms.Regression analysis identified multiple independent predictors of the child’s GI complaints,which were similar to the predictors of the child’s non-GI symptoms(mother’s IBS status,child psychological symptoms,child catastrophizing,and child age).CONCLUSION:Multiple factors influence the reporting of children’s gastrointestinal and non-gastrointestinal symptoms.The clustering of illness within families is best understood using a model that incorporates all these factors.

Effects of the Novel Anti-Asthenic Drug Ladasten on Behavior and T-Cell Subsets Alterations in a Social Defeat Animal Model of Depression

The aim of the present study was to investigate the effects of the anti-asthenic drug ladasten on behavioral patterns and T-cell subsets in blood, spleen, and thymus in socially stressed male C57Bl/6 mice. Mice subjected to social defeat stress (SDS) for 25 days developed a depressive-like phenotype. The submissive SDS animals were assigned to one of two treatment groups: one group was treated with ladasten (30 mg/kg, i.p.) for up to 5 days, and the other one was administered vehicle as a control. Twenty four hours after the last injection, behavioral parameters were tested, and trunk blood and tissue samples were collected. SDS mice from the vehicle-treated group showed a subordinate and passive avoidance behavior with significantly decreased spontaneous locomotor activity (SLA) and exhibited impaired parameters in the forced swimming test (FST). Changes in behavioral status were correlated with an increase spleen weight, a decrease in thymic index and a shift in the CD4/CD8 balance toward T-cytotoxic cells. The behavior parameters were reversed in the group treated with ladasten compared to the untreated SDS group and were similar to those of unstressed mice. Treatment of socially stressed mice with ladasten normalized the amount of T-lymphocyte cells in the blood, spleen, and thymus. These findings support the notion that depression is accompanied by cell-mediated immune activation and that targeting this pathway may be a new therapeutic approach for treatment. Furthermore, our data support further investigations of ladasten as a potent anti-depressive drug which can be used alone as well as in combination with other anti-depressants.

Effects of therapeutic horseback riding on post-traumatic stress disorder in military veterans

Background:Large numbers of post-deployment U.S.veterans are diagnosed with post-traumatic stress disorder(PTSD)and/or traumatic brain injury(TBI),leading to an urgent need for effective interventions to reduce symptoms and increase veterans’coping.PTSD includes anxiety,flashbacks,and emotional numbing.The symptoms increase health care costs for stress-related illnesses and can make veterans’civilian life difficult.Methods:We used a randomized wait-list controlled design with repeated measures of U.S.military veterans to address our specific aim to test the efficacy of a 6-week therapeutic horseback riding(THR)program for decreasing PTSD symptoms and increasing coping self-efficacy,emotion regulation,social and emotional loneliness.Fiftyseven participants were recruited and 29 enrolled in the randomized trial.They were randomly assigned to either the horse riding group(n=15)or a wait-list control group(n=14).The wait-list control group experienced a 6-week waiting period,while the horse riding group began THR.The wait-list control group began riding after 6 weeks of participating in the control group.Demographic and health history information was obtained from all the participants.PTSD symptoms were measured using the standardized PTSD Checklist-Military Version(PCL-M).The PCL-M as well as other instruments including,The Coping Self Efficacy Scale(CSES),The Difficulties in Emotion Regulation Scale(DERS)and The Social and Emotional Loneliness Scale for Adults-short version(SELSA)were used to access different aspects of individual well-being and the PTSD symptoms.Results:Participants had a statistically significant decrease in PTSD scores after 3 weeks of THR(P≤0.01)as well as a statistically and clinically significant decrease after 6 weeks of THR(P≤0.01).Logistic regression showed that participants had a 66.7%likelihood of having lower PTSD scores at 3 weeks and 87.5%likelihood at 6 weeks.Under the generalized linear model(GLM),our ANOVA findings for the coping self-efficacy,emotion regulation,and social and emotional loneliness did not reach statistical significance.The results for coping self-efficacy and emotion regulation trended in the predicted direction.Results for emotional loneliness were opposite the predicted direction.Logistic regression provided validation that outcome effects were caused by riding longer.Conclusion:The findings suggest that THR may be a clinically effective intervention for alleviating PTSD symptoms in military veterans.

Biological Trajectory for Psychosocial Risk Factors in Psychiatric Disorders—A Concept Based Review

Current understanding of mental disorders is based upon “biopsychosocial model”. Research also suggests what biological changes take place in a particular disorder as well as nature of risk which arises from psychological, social and environmental conditions. However it remains unclear how these psychosocial and environmental risk factors interact with biological factors which lead to clinical syndromes. This paper examines interrelationship of psychosocial and environmental risk and biological changes observed in mental disorders and tries to identify the possibility of a pathway of the psychopathology of psychiatric disorders. The review aims to demonstrate that significant advances in the fields of psychosocial, cultural, anthropological and neurobiological research provide novel insights into the etiology of mental disorders. There are neurochemical, functional and structural neurobiological, neurocognitive, immunological findings and findings from gene-environment interaction that appears promising. However these findings are in an isolated manner. Comprehensive studies examining major biological changes together in relation to psychosocial risk factors are lacking. Every individual reacts differently to the same environmental risk while there tends to be similarities in individual outcome in response to such stressors. The findings though robust independently, remain very preliminary to suggest a sequential trajectory for developing a clear pathway for pathogenesis. It is currently unclear whether there is a differential psychopathological impact of psychosocial stressors in different cultures despite the extensive variability both between and within major social groups and societies. Further research investigating modifiable and non-modifiable risk factors in context of prevailing socio-economic conditions is urgently needed to plan effective interventions.

论长寿内卷化

进入长寿时代后,农村老年人在其高龄阶段的生命历程中,会遭遇各种负性生活事件。伴随其机体衰退,他们会不可避免地坠入巨大的生活风险之中。结合中国传统的老龄观,通过对“内卷化”这一概念的辨析和创造性转化,可以构建“长寿内卷化”的概念,以理解当前农村高龄老年人的生活风险状态。当高龄老年人的生命历程步入内卷点之后,其寿命虽然仍然在延长,但由于各种负性生命事件的发生和影响,生命质量却开始下滑,与理想状态相反的是,这段生命历程将持续进入病寿、苦寿、辱寿等单一存在或同时并存的生活风险状态;当这一曲线下滑至接近生命质量轴的交叉点时,它意味着高龄老年人生命主动或被动的终结。支撑从长寿内卷化到生活风险发生的机制是,城镇化进程带来的社会压力通过环状结构的新家庭结构形式向高龄老年人转移。秉持积极老龄观,加强政策干预,实现长寿去内卷化,是长寿时代所必需面对的重要议题。作为一个分析性概念的“长寿内卷化”,不仅对理解当前农村高龄老年人的生活风险具有理论意义和政策意义,将来也同样适用于分析城市高龄老年人的生活风险状况。

Animal models for posttraumatic stress disorder: An overview of what is used in research

Posttraumatic stress disorder(PTSD) is a common anxiety disorder characterised by its persistence of symptoms after a traumatic experience. Although some patients can be cured, many do not benefit enough from the psychological therapies or medication strategies used. Many researchers use animal models to learn more about the disorder and several models are available. The most-used physical stressor models are single-prolonged stress, restraint stress, foot shock, stress-enhanced fear learning, and underwater trauma. Common social stressors are housing instability, social instability, earlylife stress, and social defeat. Psychological models are not as diverse and rely on controlled exposure to the test animal's natural predator. While validation of these models has been resolved with replicated symptoms using analogous stressors, translating new findings to human patients remains essential for their impact on the field. Choosing a model to experiment with can be challenging; this overview of what is possible with individual models may aid in making a decision.
