Stress physiology and inflammation

وَنُوحًا إِذۡ نَادَىٰ مِن قَبۡلُ فَٱسۡتَجَبۡنَا لَهُۥ فَنَجَّيۡنَٰهُ وَأَهۡلَهُۥ مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

Long before that, We answered Noah when he cried out to Us: We saved him and his family from the great calamity

وَنَجَّيۡنَٰهُمَا وَقَوۡمَهُمَا مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

We saved them and their people from great distress

وَنَجَّيۡنَٰهُ وَأَهۡلَهُۥ مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

We saved him and his people from great distress

قُلِ ٱللَّهُ يُنَجِّيكُم مِّنۡهَا وَمِن كُلِّ كَرۡبࣲ ثُمَّ أَنتُمۡ تُشۡرِكُونَ

Say, ‘God rescues you from this and every distress; yet still you worship others beside Him.’

وَلَمَّا بَلَغَ أَشُدَّهُۥٓ ءَاتَيۡنَٰهُ حُكۡمࣰ ا وَعِلۡمࣰ اۚ وَكَذَٰلِكَ نَجۡزِي ٱلۡمُحۡسِنِينَ

When he reached maturity, We gave him judgement and knowledge: this is how We reward those who do good

وَلَا تَقۡرَبُواْ مَالَ ٱلۡيَتِيمِ إِلَّا بِٱلَّتِي هِيَ أَحۡسَنُ حَتَّىٰ يَبۡلُغَ أَشُدَّهُۥۚ وَأَوۡفُواْ ٱلۡكَيۡلَ وَٱلۡمِيزَانَ بِٱلۡقِسۡطِۖ لَا نُكَلِّفُ نَفۡسًا إِلَّا وُسۡعَهَاۖ وَإِذَا قُلۡتُمۡ فَٱعۡدِلُواْ وَلَوۡ كَانَ ذَا قُرۡبَىٰۖ وَبِعَهۡدِ ٱللَّهِ أَوۡفُواْۚ ذَٰلِكُمۡ وَصَّىٰكُم بِهِۦ لَعَلَّكُمۡ تَذَكَّرُونَ

Stay well away from the property of orphans, except with the best [intentions], until they come of age; give full measure and weight, according to justice’- We do not burden any soul with more than it can bear- ‘ when you speak, be just, even if it concerns a relative; keep any promises you make in God’s name. This is what He commands you to do, so that you may take heed’

And mention Noah what follows Nūhan substitutes for it when he called when he supplicated to God against his people — with the words My Lord do not leave upon the earth any inhabitant from among the disbelievers … to the end of the verse Q. 7126 before that is before the time of Abraham and Lot. And We responded to him and delivered him and his people who were in the Ark with him from the great agony namely from drowning and his people’s denial of him.

and We delivered them and their people the Children of Israel from the great distress namely Pharaoh’s enslavement of them.

And We delivered him and his family from the great distress which was the drowning

And (remember) Nuh, when he cried (to Us) aforetime. We answered to his invocation and saved him and his family from the great distress (76)We helped him against the people who denied Our Ayat. Verily, they were a people given to evil. So We drowned them all (77) Nuh and His People Allah tells us how He responded to His servant and Messenger Nuh, peace be upon him, when he prayed to Him against his people for their disbelief in him: فَدَعَا رَبَّهُ أَنِّي مَغْلُوبٌ فَانتَصِرْ (Then he invoked his Lord (saying): "I have been overcome, so help (me)!")(54:10) وَقَالَ نُوحٌ رَّبِّ لَا تَذَرْ عَلَى الْأَرْضِ مِنَ الْكَافِرِينَ دَيَّارًا - إِنَّكَ إِن تَذَرْهُمْ يُضِلُّوا عِبَادَكَ وَلَا يَلِدُوا إِلَّا فَاجِرًا كَفَّارًا (And Nuh said: "My Lord! Leave not any inhabitant of the disbelievers on the earth! If You leave them, they will mislead Your servants, and they will beget none but wic

And, indeed We gave Our grace to Musa and Harun (114)And We saved them and their people from the great distress (115)And helped them, so that they became the victors (116)And We gave them the clear Scripture (117)And guided them to the right path (118)And We left for them among the later generations (119)"Salam (peace!) be upon Musa and Harun! (120)Verily, thus do We reward the doers of good (121)Verily, they were two of Our believing servants (122) Musa and Harun Allah tells us how He blessed Musa and Harun with prophethood and how He saved them, along with those who believed, from the oppression of Fir'awn and his people, who had persecuted them by killing their sons and sparing their women, and by forcing them to do the most menial tasks, then ultimately He caused them to prevail over them and to seize their lands and their wealth and all that they had spent their entire lives amass

And indeed Nuh invoked Us, and We are the best of those who answer (75)And We rescued him and his family from the great distress (76)And, his progeny, them We made the survivors (77)And left for him (a goodly remembrance) among the later generation (78)"Salam (peace!) be upon Nuh among the all creatures! (79)Verily, thus We reward the gooddoers (80)Verily, he [Nuh] was one of Our believing servants (81)Then We drowned the others (82) Nuh and His People When Allah tells us about how most of the early people went astray from the path of salvation, He starts the detailed explanation of that with the story of Nuh and the rejection of his people. Only a few of Nuh's people believed in him, despite the long period of time he spent among them. He stayed among them for one thousand years less fifty, and after he stayed among them for so long and their disbelief became too much for him to bear

Narrated Abu Sa`id Al-Khudri and Abu Huraira:The Prophet (ﷺ) said, "No fatigue, nor disease, nor sorrow, nor sadness, nor hurt, nor distress befalls a Muslim, even if it were the prick he receives from a thorn, but that Allah expiates some of his sins for that

Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "The example of a believer is that of a fresh tender plant; from whatever direction the wind comes, it bends it, but when the wind becomes quiet, it becomes straight again. Similarly, a believer is afflicted with calamities (but he remains patient till Allah removes his difficulties.) And an impious wicked person is like a pine tree which keeps hard and straight till Allah cuts (breaks) it down when He wishes." (See Hadith No. 558, Vol)

Umm Al-Mundhir said:"The Messenger of Allah (ﷺ) entered upon me, while `Ali was with him, and we had a cluster of unripe dates hanging." She said: "The Messenger of Allah (ﷺ) began eating, and `Ali ate with him. The Messenger of Allah (ﷺ) said to `Ali: 'Stop, stop, for you are still recovering.' So `Ali sat and the Prophet (ﷺ) ate." She said: "I made some chard and barley for them, so the Prophet (ﷺ) said: 'O `Ali eat from this, for indeed it will be more suitable for you." Another chain reports a similar narration

Disruption of multisystem responses to stress in type 2 diabetes: investigating the dynamics of allostatic load.: Psychological stress-related processes are thought to contribute to the development and progression of type 2 diabetes, but the biological mechanisms involved are poorly understood. Here, we tested the notion that people with type 2 diabetes experience chronic allostatic load, manifest as dynamic disturbances in reactivity to and recovery from stress across multiple (cardiovascular, neuroendocrine, inflammatory, metabolic) biological systems, coupled with heightened experience of chronic life st

Subjects were randomly allocated to take either 50,000 IU vitamin D every 2 weeks plus 2000 mg/day omega-3 fatty acid from fish oil (n = 30) or pla

The effect of Nigella sativa (black seed) on biomarkers of inflammation and oxidative stress: an updated systematic review and meta-analysis of randomized controlled trials.: Objective: This study was conducted to assess the effect of Nigella sativa (N. sativa) supplementation on inflammatory and oxidative markers among the adult population. Methods: We carried out a comprehensive, systematic search of Scopus, Embase, Cochrane Library, Web of Science, PubMed, and Google Scholar till December 2022. A random-effects model was used to estimate the overall effect size. Results: In total, twenty trials consisting of 1086 participants were included in the meta-analysis. Fi

Cumulative meta-analysis of interleukins 6 and 1β, tumour necrosis factor α and C-reactive protein in patients with major depressive disorder.: Cumulative meta-analyses are used to evaluate the extent to which further studies are needed to confirm or refute a hypothesis. We used this approach to assess observational evidence on systemic inflammation in individuals with major depressive disorder. We identified 58 studies of four common inflammatory markers in a literature search of PubMed, Embase and PsychInfo databases in May 2014. Pooled data from the earliest eight studies already showed an association between interleukin-6 concentrat

Towards a consensus definition of allostatic load: a multi-cohort, multi-system, multi-biomarker individual participant data (IPD) meta-analysis.: Background: Allostatic load (AL) is a multi-system composite index for quantifying physiological dysregulation caused by life course stressors. For over 30 years, an extensive body of research has drawn on the AL framework but has been hampered by the lack of a consistent definition. Methods: This study analyses data for 67,126 individuals aged 40-111 years participating in 13 different cohort studies and 40 biomarkers across 12 physiological systems: hypothalamic-pituitary-adrenal (HPA) axis, s

Cytokines and C-reactive protein alterations with respect to cognitive impairment in schizophrenia and bipolar disorder: A systematic review.: Background: The aim of this article was to perform a systematic review of studies investigating the association between peripheral levels of cytokines and C-reactive protein (CRP), cytokine gene polymorphisms and cognition in patients with schizophrenia and bipolar disorder (BD). Methods: The following databases: PubMed, CINAHL Complete, Academic Search Complete, ERIC and Health Source: Nursing/Academic Edition databases were searched according to the PRISMA guidelines. We included studies that

Socioeconomic status over the life course and allostatic load in adulthood: results from the Northern Swedish Cohort.

Background: Although several studies have reported rather consistent associations between socioeconomic status (SES) and allostatic load (AL), so far no study has examined the influence of SES over the life course on AL. The aim of the present study was to investigate the association between SES over the life course and AL in mid-adulthood, guided by the conceptual models of cumulative risk, critical period and social chain of risk. Methods: The sample comprises a 27-year prospective cohort (n=1071) from northern Sweden. Participants (n=855, 79.8%) completed questionnaires at the ages of 16, 21, 30 and 43 years. A health examination was performed at age 43 years after an overnight fast, including physical examination and blood sampling, and participants completed 1-day salivary cortisol sampling (four samples). SES was based on parental occupation at age 16 years and participants' own oc…

Mediators of the relationship between socioeconomic status and allostatic load in the Chicago Health, Aging, and Social Relations Study (CHASRS).

Low socioeconomic status (SES) has been associated with higher levels of allostatic load (AL). Posited mechanisms for this association include stress, personality, psychosocial variables, coping, social networks, and health behaviors. This study examines whether these variables explain the SES-AL relationship in a population-based sample of 208 51- to 69-year-old White, Black, and Hispanic adults in the Chicago Health, Aging, and Social Relations Study. AL was based on nine markers of physiological dysregulation. SES was inversely associated with a composite measure of AL; hostility and poor sleep quality helped to explain the association between AL and SES. Factor analyses revealed four AL components corresponding to the bodily systems of interest. SES was significantly associated with two AL components, suggesting that the effects of SES on physiological dysregulation are specific to c…

Racial and ethnic patterns of allostatic load among adult women in the United States: findings from the National Health and Nutrition Examination Survey 1999-2004.

Objective: This study provides a descriptive sociodemographic profile of allostatic load (AL) among adult women of all age groups, focusing on how age patterns of AL vary across racial/ethnic groups. Allostatic load, an index of cumulative physiological dysregulation, captures how the cumulative impact of physiological stress responses from person-environment interactions causes wear and tear on the body's regulatory systems, which in turn can lead to disease outcomes and health disparities. Methods: Using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2004, this study examines AL in a nationally representative sample of women ≥18 years of age (n=5765). Measures of AL using 10 biomarkers representing cardiovascular, inflammatory, and metabolic system functioning were created. Multivariate negative binomial regression models were used, and predicted AL scores…

Critical biological pathways for chronic psychosocial stress and research opportunities to advance the consideration of stress in chemical risk assessment.

Emerging evidence suggests that psychosocial stress and toxicants may interact to modify health risks. Stress-toxicant interactions could be important in chemical risk assessment, but these interactions are poorly understood and additional research is necessary to advance their application. Environmental health research can increase knowledge of these interactions by exploring hypotheses on allostatic load, which measures the cumulative impacts of stress across multiple physiological pathways, using knowledge about physiological pathways for stress-related health effects, and evidence of common target pathways for both stress and toxicants. In this article, critical physiological pathways for stress-related health effects are discussed, with specific attention to allostatic load and stress-toxicant interactions, concluding with research suggestions for potential applications of such rese…

Kindergarten stressors and cumulative adrenocortical activation: the "first straws" of allostatic load?

Using an ethnically diverse longitudinal sample of 338 kindergarten children, this study examined the effects of cumulative contextual stressors on children's developing hypothalamic-pituitary-adrenocortical (HPA) axis regulation as an early life indicator of allostatic load. Chronic HPA axis regulation was assessed using cumulative, multiday measures of cortisol in both the fall and spring seasons of the kindergarten year. Hierarchical linear regression analyses revealed that contextual stressors related to ethnic minority status, socioeconomic status, and family adversity each uniquely predicted children's daily HPA activity and that some of those associations were curvilinear in conformation. Results showed that the quadratic, U-shaped influences of family socioeconomic status and family adversity operate in different directions to predict children's HPA axis regulation. Results furth…

Marital conflict, respiratory sinus arrhythmia, and allostatic load: interrelations and associations with the development of children's externalizing behavior.

Allostatic load theory hypothesizes that stress and the body's responses to stressors contribute to longer term physiological changes in multiple systems over time (allostasis), and that shifts in how these systems function have implications for adjustment and health. We investigated these hypotheses with longitudinal data from two independent samples (n = 413; 219 girls, 194 boys) with repeated measures at ages 8, 9, 10, and 11. Initial parental marital conflict and its change over time indexed children's exposure to an important familial stressor, which was examined in interaction with children's respiratory sinus arrhythmia (RSA) reactivity to laboratory tasks (stress response) to predict children's basal levels of RSA over time. We also investigated children's sex as an additional possible moderator. Our second research question focused on examining whether initial levels and changes…

Allostasis and allostatic load in the context of poverty in early childhood.

This paper examined the relation of early environmental adversity associated with poverty to child resting or basal level of cortisol in a prospective longitudinal sample of 1135 children seen at 7, 15, 24, 35, and 48 months of age. We found main effects for poor housing quality, African American ethnicity, and low positive caregiving behavior in which each was uniquely associated with an overall higher level of cortisol from age 7 to 48 months. We also found that two aspects of the early environment in the context of poverty, adult exits from the home and perceived economic insufficiency, were related to salivary cortisol in a time-dependent manner. The effect for the first of these, exits from the home, was consistent with the principle of allostatic load in which the effects of adversity on stress physiology accumulate over time. The effect for perceived economic insufficiency was one…

Hypocortisolism as a potential marker of allostatic load in children: associations with family risk and internalizing disorders.

Although the majority of research attention to the hypothalamic-pituitary-adrenal (HPA) axis in stress-related disorders and as a marker of allostatic load has focused on overactivation of this stress system, theory and data clearly indicate that underactivation is also an important type of dysregulation. In the current study we focused on low cortisol, exploring a constellation of risk factors including stress exposure, maternal depression, and attenuated basal and stress reactive cortisol in two samples of children. The first sample was comprised of 110 preschoolers living in high-stress environments. Cortisol was assessed across the day at home and at child care as well as across two stress paradigms. These data were used to classify whether children's HPA axis activity was attenuated. Serious family financial strain, maternal depression, and attenuated cortisol all made unique contri…

Early adversity and adult health outcomes.

Adversity in childhood has effects on mental and physical health, not only in childhood but across the lifespan. A chief task of our research has been to define the pathways by which childhood experience has these surprising health outcomes, often decades later. The concept of allostatic load, which refers to dysregulations across major biological regulatory systems that have cumulative interacting adverse effects over time, provides a mechanism for understanding these relations and defining specific pathways. To chart these pathways, we examine early childhood socioeconomic status, family environment, and genetic predispositions as antecedents to socioemotional functioning/psychological distress; and neural responses to threat that have downstream effects on major stress regulatory systems, ultimately culminating in risks to mental and physical health outcomes. This integrative approach…

Allostatic load among non-Hispanic Whites, non-Hispanic Blacks, and people of Mexican origin: effects of ethnicity, nativity, and acculturation.

Objectives: We investigated ethnic differences in allostatic load in a population-based sample of adults living in Texas City, TX, and assessed the effects of nativity and acculturation status on allostatic load among people of Mexican origin. Methods: We used logistic regression models to examine ethnic variations in allostatic load scores among non-Hispanic Whites, non-Hispanic Blacks, and people of Mexican origin. We also examined associations between measures of acculturation and allostatic load scores among people of Mexican origin only. Results: Foreign-born Mexicans were the least likely group to score in the higher allostatic load categories. Among individuals of Mexican origin, US-born Mexican Americans had higher allostatic load scores than foreign-born Mexicans, and acculturation measures did not account for the difference. Conclusions: Our findings expand on recent research f…

The Boston Puerto Rican Health Study, a longitudinal cohort study on health disparities in Puerto Rican adults: challenges and opportunities.

Background: The Boston Puerto Rican Health Study is an ongoing longitudinal cohort study designed to examine the role of psychosocial stress on presence and development of allostatic load and health outcomes in Puerto Ricans, and potential modification by nutritional status, genetic variation, and social support. Methods: Self-identified Puerto Ricans, aged 45-75 years and residing in the Boston, MA metro area, were recruited through door-to-door enumeration and community approaches. Participants completed a comprehensive set of questionnaires and tests. Blood, urine and salivary samples were extracted for biomarker and genetic analysis. Measurements are repeated at a two-year follow-up. Results: A total of 1500 eligible participants completed baseline measurements, with nearly 80% two-year follow-up retention. The majority of the cohort is female (70%), and many have less than 8th grade…

Clinical assessment of allostatic load and clinimetric criteria.

The concept of allostasis emphasizes that healthy functioning requires continual adjustments to the internal physiological milieu. Allostatic load reflects the cumulative effects of stressful experiences in daily life. When the cost of chronic exposure to fluctuating or heightened neural or neuroendocrine responses exceeds the coping resources of an individual, allostatic overload ensues. So far these issues have been addressed only on pathophysiological terms that do not find application in clinical settings. However, several features that have been described in psychosomatic research may allow the assessment of allostatic load on clinical grounds. Clinimetric criteria for the determination of allostatic overload are suggested. They are based on: (a) the presence of a stressor exceeding individual coping skills, and (b) clinical manifestations of distress. They may provide specification…

Racial/ethnic disparities in all-cause mortality in U.S. adults: the effect of allostatic load.

Objective: We investigated the association between a cumulative biological risk or allostatic score and all-cause mortality risk. We used 13,715 records of participants aged 25 years and older from the Third National Health and Nutrition Examination Survey (NHANES III) linked to the National Death Index. Methods: We specified all-cause mortality using the underlying cause of death in the death certificate. We calculated time to death from interview date through December 31, 2000, as person-years of follow-up using the NHANES III interview month and year. We used Cox proportional hazards regression to estimate hazard ratios (HRs) relating all-cause mortality risk for those with an allostatic score of 2 and > or = 3 relative to those with an allostatic score of < or = 1. Results: After controlling for age, gender, race/ethnicity, education, and income, mortality rates were 40% (HR = 1.40, …

Allostatic load is associated with chronic conditions in the Boston Puerto Rican Health Study.

Puerto Ricans living in the United States mainland present multiple disparities in prevalence of chronic diseases, relative to other racial and ethnic groups. Allostatic load (AL), or the cumulative wear and tear of physiological responses to stressors such as major life events, social and environmental burden, has been proposed as a possible mechanism for the inequalities observed in minority groups, but has not been studied in Puerto Ricans. The aim of this study was to determine the association of AL to six chronic diseases (abdominal obesity, hypertension, diabetes, and self-reported cardiovascular disease (CVD), arthritis and cancer) in Puerto Ricans, and to contrast AL to metabolic syndrome (MetS). Participants of the Boston Puerto Rican Health Study (n=1116, ages 45-75 years) underwent a home-based interview, where questionnaires were completed and biological samples collected. A …

Allostatic load and frailty in older adults.

Objectives: To examine the association between allostatic load (AL), an index of multisystem physiological dysregulation, and frailty development over a 3-year follow-up in a sample of older adults. Design: Longitudinal cohort study. Setting: Community. Participants: High-functioning men and women aged 70 to 79 at study entry. Measurements: Multisystem physiological dysregulation, or AL, was assessed according to 13 biomarkers of cardiovascular, endocrine, immune, and metabolic function. An AL score was computed as the total number of biomarkers for which participant values fell into high-risk biomarker quartiles. Frailty status (not frail, intermediate frail, frail) was determined according to the total number of five indicators of frailty: weight loss, exhaustion, weak grip, slow gait, and low physical activity. The association between level of AL at baseline and frailty status 3 years…

Marital satisfaction, recovery from work, and diurnal cortisol among men and women.

Design: Multilevel modeling was used to model relationships between salivary cortisol, daily diary ratings of work experiences, and Marital Adjustment Test scores (Locke & Wallace, 1959), in a sample of 60 adults who sampled saliva 4 times per day over 3 days. Results: Among women but not men, marital satisfaction was significantly associated with a stronger basal cortisol cycle, with higher morning values and a steeper decline across the day. For women but not men, marital satisfaction moderated the within-subjects association between afternoon and evening cortisol level, such that marital quality appeared to bolster women's physiological recovery from work. For both men and women, evening cortisol was lower than usual on higher-workload days, and marital satisfaction augmented this association among women. Men showed higher evening cortisol after more distressing social experiences at …

Homeless street children in Nepal: use of allostatic load to assess the burden of childhood adversity.

As challenges to child well-being through economic disadvantage, family disruption, and migration or displacement escalate world wide, the need for cross-culturally robust understanding of childhood adversity proportionately increases. Toward this end, developmental risk was assessed in four contrasting groups of 107 Nepali children ages 10-14 years that represent distinctive, common conditions in which contemporary children grow up. Relative cumulative burden (allostatic load) indexed by multiple dimensions of physical and psychosocial stress was ascertained among homeless street boys and three family-based groups, from poor urban squatter settlements, urban middle class, and a remote rural village. Biomarkers of stress and vulnerability to stress included growth status, salivary cortisol, antibodies to Epstein-Barr virus, acute phase inflammatory responses (alpha1-antichymotrypsin), an…

Do chronic stressors lead to physiological dysregulation? Testing the theory of allostatic load.

Objectives: To explore three questions: 1) Do chronic stressors predict physiological dysregulation? 2) Is that relationship moderated by characteristics of the individual and his or her social environment? and 3) Do perceived levels of stress mediate the relationship between stressors and dysregulation? Methods: Data come from a nationally representative, longitudinal study of older Taiwanese (n = 916). Regression models are used to examine the relationship between the number of life challenges (i.e., stressors) during 1996 to 2000 and physiological dysregulation (in 2000) based on 16 biomarkers that reflect neuroendocrine function, immune system, cardiovascular function, and metabolic pathways. We include interaction terms to test whether psychosocial vulnerability moderates the impact of stressors. Additional models evaluate the mediating effects of perceived stress. Results: We find …

Repeated sleep restriction in rats leads to homeostatic and allostatic responses during recovery sleep.

Recent studies indicate that chronic sleep restriction can have negative consequences for brain function and peripheral physiology and can contribute to the allostatic load throughout the body. Interestingly, few studies have examined how the sleep-wake system itself responds to repeated sleep restriction. In this study, rats were subjected to a sleep-restriction protocol consisting of 20 h of sleep deprivation (SD) followed by a 4-h sleep opportunity each day for 5 consecutive days. In response to the first 20-h SD block on day 1, animals responded during the 4-h sleep opportunity with enhanced sleep intensity [i.e., nonrapid eye movement (NREM) delta power] and increased rapid eye movement sleep time compared with baseline. This sleep pattern is indicative of a homeostatic response to acute sleep loss. Remarkably, after the 20-h SD blocks on days 2-5, animals failed to exhibit a compen…

PPAR-α Hypermethylation in the Hippocampus of Mice Exposed to Social Isolation Stress Is Associated with Enhanced Neuroinflammation and Aggressive Behavior.

Social behavioral changes, including social isolation or loneliness, increase the risk for stress-related disorders, such as major depressive disorder, posttraumatic stress disorder (PTSD), and suicide, which share a strong neuroinflammatory etiopathogenetic component. The peroxisome-proliferator activated receptor (PPAR)-α, a newly discovered target involved in emotional behavior regulation, is a ligand-activated nuclear receptor and a transcription factor that, following stimulation by endogenous or synthetic ligands, may induce neuroprotective effects by modulating neuroinflammation, and improve anxiety and depression-like behaviors by enhancing neurosteroid biosynthesis. How stress affects epigenetic mechanisms with downstream effects on inflammation and emotional behavior remains poorly understood. We studied the effects of 4-week social isolation, using a mouse model of PTSD/suicid…

Depression, dementia and immune dysregulation.

Major depression is a prevalent illness that increases the risk of several neurological conditions. These include stroke, cardiovascular disease, and dementia including Alzheimer's disease. In this review we ask whether certain types of depression and associated loneliness may be a harbinger of cognitive decline and possibly even dementia. We propose that chronic stress and inflammation combine to compromise vascular and brain function. The resulting increases in proinflammatory cytokines and microglial activation drive brain pathology leading to depression and mild cognitive impairment, which may progress to dementia. We present evidence that by treating the inflammatory changes, depression can be reversed in many cases. Importantly, there is evidence that anti-inflammatory and antidepressant treatments may reduce or prevent dementia in people with depression. Thus, we propose a model i…

Everyday co-presence with a romantic partner is associated with lower C-reactive protein.

Social relationships are an important driver of health, and inflammation has been proposed as a key neurobiological mechanism to explain this effect. Behavioral researchers have focused on social relationship quality to further explain the association, yet recent research indicates that relationship quality may not be as robust a predictor as previously thought. Here, building on animal models of social bonds and recent theory on close relationships, we instead investigated merely being in the physical presence of one's romantic partner. Specifically, we tested the hypothesis that spending more time co-present with a loved partner in everyday life would be associated with lower C-reactive protein (CRP). Three times over the course of one month, 100 people in romantic relationships reported how much time they spent in the same physical space as their partner in the prior 24 h, in minutes,…

Preliminary insights into associations between C-reactive protein and social network dynamics.

Recent social psychoneuroimmunology models suggest bidirectional associations between social experiences and the immune system. This work posits that social relationships and networks may influence the functioning of the immune system, but we know little about the role that the immune system plays in how social networks are created and maintained. We examine how salivary C-reactive protein (CRP), as an inflammatory protein, is associated with making new and keeping existing friendship and conflicted relationships among young adult members of a social group. Participants (n = 37; 67.6% female; M age = 18.18 years, 56.81% white/non-Hispanic) provided nominations of friends and individuals with whom they have conflict at wave 1 and two months later at wave 2. At wave 1, in a group setting, participants donated saliva, later assayed for CRP. Stochastic actor-based models revealed that CRP le…

Acupuncture inhibits TXNIP-associated oxidative stress and inflammation to attenuate cognitive impairment in vascular dementia rats.

Aims: Oxidative stress and inflammation have been implicated in the pathogenesis of vascular dementia (VD). Thioredoxin-interacting protein (TXNIP) plays a vital role in oxidative stress and NOD-like receptor protein 3 (NLRP3) inflammasome activation. There is evidence that acupuncture has an antioxidative and neuroprotective effect in VD. In this study, we investigated whether acupuncture can attenuate cognitive impairment via inhibiting TXNIP-associated oxidative stress and inflammation in VD rats. Methods: Both common carotid arteries were occluded (2-vessel occlusion [2VO]) in rats to model VD. The neuroprotective effect of acupuncture was assessed by the Morris water maze and Nissl staining. Oxidative stress was assessed by detecting levels of reactive oxygen species, DNA oxidation, and antioxidase. Western blot, real-time PCR, and immunofluorescence were used to detect the expressi…
