We previously found that experimental infection with IAV affected oligodendrocyte homeostasis, which was associated with altered expression of genes involved in myelin maintenance as well as the lipidome. In this study, we sought to determine if clemastine, an antihistamine with myelin promoting properties, could reverse the effects of IAV on oligodendrocyte (OL) specific genes, as well as mitigate infection-induced cognitive impairment. Male and female C57BL/6J mice were randomized into experimental groups based on clemastine treatment, infection, and sex. Treatment with vehicle or clemastine (10mg/kg/d) commenced seven days prior to inoculation with either saline or IAV and continued throughout the experiment. Body weight was measured throughout the infection. Spatial learning and memory were assessed by Morris water maze. Sickness behavior was assessed by measuring burrowing response. Immune cell responses were determined by flow cytometry, RT-qPCR, antigen recall assays and ELISA, and viral load assessed by RT-qPCR. Hippocampal levels of neuroinflammatory (<em>Tnf, Cdkn1a</em>) and myelin (<em>Plp1</em>, <em>Mag</em>, <em>Ugt8a</em>) genes were determined by RT-qPCR. Mice infected with IAV developed weight loss, impaired cognitive flexibility, reduced burrowing behavior, altered lung immune cell infiltration, increased circulating anti-viral IgM and IgG levels and increased T cell responses to IAV epitopes. Infection increased hippocampal levels of genes associated with neuroinflammation and decreased levels of genes involved in myelination. Clemastine treatment resulted in earlier recovery of weight loss in males and increased IgM levels for both sexes, but neither affected expression levels of <em>Tnf</em> or <em>Cdkn1a</em>, nor rescued changes to oligodendrocyte genes.

METH use is a significant health concern among persons living with HIV (PWH), aggravating cognitive deficits and neuroinflammation despite of antiretrovirals, introducing elements in the microenvironment that are fundamentally differerent in relation to non-METH users, such as high levels of dopamine (DA) affecting HIV-innate immune targets.

However, decades of research evaluating the Stress-Buffering model suggests that social support can attenuate stressors' negative impacts.

This article takes a lifecourse perspective and proposes that timing of support may shape support's protective value by defining the type of protection that is provided and its operating mechanisms. Specifically, it considers three temporal scenarios: support that occurs during, after, or before stressor exposure. When support intervenes at the same developmental stage as the stressor (concurrent support), buffering effects occur wherein support prevents the development of intermediary mechanisms that reflect or increase disease risk; when support is present at a developmental stage before stressor exposure (prior support), banking effects occur such that support intervenes indirectly by fortifying the individual with resilience-promoting characteristics that in turn prevents the development of intermediary mechanisms; finally, when support arrives at a developmental stage after stressor exposure (later support), counteracting effects occur such that support offsets the impacts of intermediary mechanisms on diseases. It further posits that a match between timing of support and the linkage of interest (e.g., the stressor-mechanism path vs. the mechanism-disease path) is necessary for successful protection. The present paper discusses these postulations, reviews nascent evidence, and proposes future directions.</div></div>","PeriodicalId":72454,"journal":{"name":"Brain, behavior, & immunity - health","volume":"42 ","pages":"Article 100876"},"PeriodicalIF":3.7,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142419571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We employed a systems biology approach with 62 adolescent Lewis rats fed a Western-like high-saturated fat diet (WD, 41% kcal from fat) or a control diet (CD, 13% kcal from fat). A subset of rats underwent a 31-day model of predator exposures and social instability (PSS). Effects were assessed using behavioral tests, DTI (diffusion tensor imaging), NODDI (neurite orientation dispersion and density imaging), 16S rRNA gene sequencing for gut microbiome profiling, hippocampal microglia analysis, and targeted gene methylation. Parallel experiments on human microglia cells (HMC3) examined how palmitic acid influences cortisol-related inflammatory responses.</div><div>Rats exposed to WD and PSS exhibited deficits in sociability, increased fear/anxiety-like behaviors, food consumption, and body weight. WD/PSS altered hippocampal microstructure (subiculum, CA1, dentate gyrus), and microbiome analysis showed a reduced abundance of members of the phylum <em>Firmicutes</em>. WD/PSS synergistically promoted neuroinflammatory changes in hippocampal microglia, linked with microbiome shifts and altered <em>Fkbp5</em> expression/methylation. In HMC3, palmitate disrupted cortisol responses, affecting morphology, phagocytic markers, and cytokine release, partially mediated by FKBP5.</div><div>This study identifies gene-environment interactions that influence microglia biology and may contribute to the connection between childhood obesity and stress-related psychopathology later in life.</div></div>","PeriodicalId":72454,"journal":{"name":"Brain, behavior, & immunity - health","volume":"42 ","pages":"Article 100879"},"PeriodicalIF":3.7,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142419573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
