However, it is currently unknown how perinatal opioid exposure (POE) alters immune function. Using a clinically relevant and translatable model of POE, we have investigated how baseline immune function and the reaction to an immune stimulator, lipopolysaccharide, is influenced by <em>in utero</em> opioid exposure in adult male and female rats.

This process produces metabolites like Kynurenine (Kyn), 3-Hydroxykynurenine (3-HK), Quinolinic acid (QuinA), and Kynurenic acid (KynA), these last two acting as agonist and antagonist at glutamatergic N-methyl-D-aspartate receptors (NMDARs), respectively. NMDARs, expressed in the choroid plexus (ChP) and arteriolar smooth muscle cells, regulate blood–brain-barrier permeability and cerebral artery dilation, suggesting that KP may influence neurovascular coupling, aligning blood flow with neural energy demand. KP’s role in modulating vascular tone supports this hypothesis. Altered fractional amplitude of low-frequency fluctuations (fALFF) and disrupted default mode network (DMN) activity in mood disorders are linked to cognitive deficits possibly through neurovascular uncoupling like in neurological diseases. This makes fALFF and hemodynamic response function (HRF) potential indicators of these changes. We investigated KP associations with ChP volumes, functional-MRI at rest measures like spontaneous neural activity (fALFF) and hemodynamic response function (HRF) parameters within the default mode network (DMN), and cognitive performance in 42 MDD and 36 BD inpatients experiencing a depressive episode.</div><div>Results revealed that lower QuinA/KynA ratios and higher KynA levels predict larger ChP volumes. Higher KYN and 3-HK levels, along with lower KynA levels, were associated with increased DMN fALFF and shorter time-to-peak (TTP) in HRF, suggesting altered neurovascular coupling. Mediation analyses indicated that KP metabolites influenced cognitive performance through their effects on resting state measures, affecting global cognitive functioning score, verbal fluency, and psychomotor coordination. These findings suggest that KP metabolites modulate brain function and structure via NMDAR-mediated pathways and vascular-based mechanisms, offering insights into the cognitive impairments observed in mood disorders and identifying potential therapeutic targets.</div></div>","PeriodicalId":9199,"journal":{"name":"Brain, Behavior, and Immunity","volume":"125 ","pages":"Pages 414-427"},"PeriodicalIF":8.8,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143136663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we leveraged this unique animal model to explore mechanisms of HPA axis regulation and consequences of its genetically-based persistent hypoactivity. To this end, we examined transcriptional signature of GR<sub>Ala610Val</sub> in the hypothalamus, hippocampus, amygdala and adrenal gland in resting conditions (i.e. baseline glucocorticoid level) using mRNA sequencing. In addition, we studied transcriptome responses to two different doses of dexamethasone in the hypothalamus and hippocampus, depending on GR<sub>Ala610Val</sub>. Across tissues, GR<sub>Ala610Val</sub> consistently influenced the expression of several clustered protocadherins, particularly <em>PCDHB7</em>. Clustered protocadherins play an important role in neuronal connectivity and are implicated in different neurobiological disorders. Moreover, in line with our previous findings in blood immune cells, we found higher expression of pro-inflammatory genes, including canonical members of the TLR4 signaling pathway, in the brain of Val carriers. While the pro-inflammatory priming occurs already at resting conditions in the amygdala, in hypothalamus and hippocampus this seems to be associated with a stronger downregulation of several marker genes of homeostatic microglia, such as <em>SALL1</em>, by dexamethasone in Val carriers. Regarding the regulation of the HPA axis, GR<sub>Ala610Val</sub> showed a dose-dependent effect on the central regulator of the axis, <em>CRH</em>, suggesting a dynamic adaptation to the glucocorticoid hypersensitivity of the Val variant. In the adrenal gland, GR<sub>Ala610Val</sub> appears to downregulate cortisol production by impairing mitochondrial function.
