Subjects with a combined arterial supply by tuberothalamic and paramedian arteries to the right thalamus exhibited a lower Hamilton Anxiety scale (HAMA) score. When grouped by SVD burden, the same correlation remained in subjects with low SVD burden, whereas no difference was observed in the high SVD burden group. Interestingly, interaction effects of SVD and thalamic vascular pattern were also found affecting thalamic volume and resting-state brain activity in ventromedial prefrontal cortex (vmPFC). With moderated mediation analysis, right thalamic vascular pattern was indicated to affect anxiety through both direct (vascular pattern → HAMA score) and indirect (vascular pattern → thalamic volume → HAMA score) pathways. But high SVD burden interrupted the effects of right thalamic vascular pattern on HAMA score and thalamic volume. The finding that subjects with a combined arterial supply to the right thalamus exhibited a lower level of anxiety may suggest a novel vascular resilience for regulating anxiety. However, this vascular compensation mechanism was found to be impaired by elevated SVD burden and the disrupted inhibitory vmPFC activity caused by impaired thalamus.

However, it remains uncertain if the reduced risk might be attributable to a general psychopathology factor common to all psychiatric conditions, versus specific psychopathology factors unique to only subsets of psychiatric conditions. In an at-risk sample, we estimated the association between an enriched childhood rearing environment and a latent bifactor model that captured both general and several specific psychopathology factors. The sample consisted of 881 full sibships where (a) the biological parents had (at least) one psychiatric diagnosis, suicide, or crime at any time in their lives, and (b) where (at least) one sibling was adopted away and raised by non-biological parents and (at least) one sibling raised by the biological parents. The exposure was whether a sibling was raised by biological versus adoptive parents. The outcome was a latent bifactor model based on nine conditions, including 7 in- or outpatient psychiatric diagnoses, suicide, and crimes. We recorded these outcomes from the birth of the siblings until the end of 2013, when the siblings were 34–64 years old. We used the marginal between-within model to estimate whether the adopted-away sibling(s) had lower scores on the latent factors. The latent bifactor model based on the nine conditions consisted of one general and three specific (externalizing, internalizing, and psychotic) psychopathology factors. The adopted-away siblings scored 0.27 (95% CI: −0.36, −0.18) standard deviations lower on the latent general psychopathology factor and 0.26 (95% CI: −0.38, −0.14) standard deviations lower on the latent specific externalizing factor, compared to their biological siblings who were raised by the biological parents. This result indicates that although genetics appears important for psychiatric comorbidity, the rearing environment also appears to play a systematic role in influencing the liability toward all mental health conditions among at-risk individuals. Improving the childhood rearing environment in high-risk families could potentially mitigate children’s liability toward all psychiatric conditions.</p>","PeriodicalId":19008,"journal":{"name":"Molecular Psychiatry","volume":"15 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the underlying relationship between peripheral TREM2 and brain AD pathology has not yet been well-elucidated in the aging population. In this study, we collected 318 Chinese older adults with Aβ PET and plasma biomarker measures, including soluble TREM2 (sTREM2) and glial fibrillary acidic protein (GFAP), a proxy for astrocyte reactivity. Additionally, 129 participants underwent tau PET scans. We explored the association between plasma sTREM2, GFAP, and primary AD pathology. Plasma sTREM2 was negatively associated with reduced temporal tau PET burden in participants with abnormal Aβ and tau pathology. Higher plasma sTREM2 was related to the weaker association of Aβ pathology and plasma phosphorylated tau with tau PET increases. In contrast, elevated plasma GFAP was related to greater Aβ and tau PET burden along with stronger Aβ-related tau accumulation. Finally, higher plasma sTREM2 was linked to attenuated strength of the association between plasma GFAP and tau PET increases at both pre-defined regions of interest and voxel levels. Altogether, our findings suggest distinct relationships between plasma sTREM2 and GFAP with cerebral tau pathology, providing novel insights into the roles of peripheral TREM2 signaling and astrocytic reactivity in AD neuropathological development.

Prior studies in human smokers have used positron emission tomography (PET) to characterize differences in postsynaptic nicotinic acetylcholine receptors (nAChRs).

To date, there is a paucity of studies imaging presynaptic targets in human smokers. We conducted an initial PET neuroimaging study with [<sup>18</sup>F]VAT, which indexes VAChT availability (presynaptic marker of cholinergic tone), in 12 healthy smokers and 13 demographically-matched healthy non-smokers. We tested for group differences in VAChT availability, measured as total distribution volume (V<sub>T</sub>), in the striatum (main region of interest) and in multiple cortical and subcortical extrastriatal regions. Within smokers, we also tested correlations between VAChT availability and indices of smoking chronicity and tobacco self-administration. Smokers had higher [<sup>18</sup>F]VAT V<sub>T</sub> than non-smokers in multiple cortical and subcortical regions (<i>p</i> < 0.05<sub>uncorrected</sub>).

This study provides first-line evidence of presynaptic cholinergic differences between smokers and non-smokers, such that VAChT is upregulated in smokers and associated with chronicity.

In this study, we performed fecal shotgun metagenomic analysis on a Chinese cohort with 476 participants across five stages of AD pathology to characterize stage-specific alterations in gut microbiota and evaluate their diagnostic potential. We discovered extensive gut dysbiosis that is associated with neuroinflammation and neurotransmitter dysregulation, with over 10% of microbial species and gene families showing significant alterations during AD progression. Furthermore, we demonstrated that microbial gene families exhibited strong diagnostic capabilities, evidenced by an average AUC of 0.80 in cross-validation and 0.75 in independent external validation. In the optimal model, the most discriminant gene families are primarily involved in the metabolism of carbohydrates, amino acids, energy, glycan and vitamins. We found that stage-specific microbial gene families in AD pathology could be validated by an in vitro gut simulator and were associated with specific genera. We also observed that the gut microbiota could affect the progression of cognitive decline in 5xFAD mice through fecal microbiota transplantation, which could be used for early intervention of AD.

Predicting antidepressant efficacy is challenging due to MDD’s complex and varied neuropathology. Identifying biomarkers for antidepressant treatment requires thorough analysis of clinical trial data. Multimodal neuroimaging, combined with advanced data-driven methods, can enhance our understanding of the neurobiological processes influencing treatment outcomes. To address this, we analyzed resting-state fMRI and EEG connectivity data from 130 patients treated with sertraline and 135 patients with placebo from the Establishing Moderators and Biosignatures of Antidepressant Response in Clinical Care (EMBARC) study. A deep learning framework was developed using graph neural networks to integrate data-augmented connectivity and cross-modality correlation, aiming to predict individual symptom changes by revealing multimodal brain network signatures. The results showed that our model demonstrated promising prediction accuracy, with an R<sup>2</sup> value of 0.24 for sertraline and 0.20 for placebo. It also exhibited potential in transferring predictions using only EEG. Key brain regions identified for predicting sertraline response included the inferior temporal gyrus (fMRI) and posterior cingulate cortex (EEG), while for placebo response, the precuneus (fMRI) and supplementary motor area (EEG) were critical. Additionally, both modalities identified the superior temporal gyrus and posterior cingulate cortex as significant for sertraline response, while the anterior cingulate cortex and postcentral gyrus were common predictors in the placebo arm. Additionally, variations in the frontoparietal control, ventral attention, dorsal attention, and limbic networks were notably associated with MDD treatment. By integrating fMRI and EEG, our study established novel multimodal brain network signatures to predict individual responses to sertraline and placebo in MDD, providing interpretable neural circuit patterns that may guide future targeted interventions.
