We show that all symptom domains (negative and PHEMFP) may be used to derive a single latent trait called overall severity of schizophrenia (OSOS). In addition, neurocognitive test results may be used to extract a general cognitive decline (G-CoDe) index, based on executive function, attention, semantic and episodic memory, and delayed recall scores. According to partial least squares analysis, the impacts of adverse outcome pathways (AOPs) on OSOS are partially mediated by increasing G-CoDe severity. The AOPs include neurotoxic cytokines and chemokines, oxidative damage to proteins and lipids, IgA responses to neurotoxic tryptophan catabolites, breakdown of the vascular and paracellular pathways with translocation of Gram-negative bacteria, and insufficient protection through lowered antioxidant levels and impairments in the innate immune system. Unsupervised machine learning identified a new schizophrenia endophenotype class, named major neurocognitive psychosis (MNP), which is characterised by increased negative symptoms and PHEMFP, G-CoDe and the above-mentioned AOPs. Based on these pathways and phenome features, MNP is a distinct endophenotype class which is qualitatively different from simple psychosis (SP). It is impossible to draw any valid conclusions from research on schizophrenia that ignores the MNP and SP distinctions.</p>","PeriodicalId":7066,"journal":{"name":"Acta Neuropsychiatrica","volume":"35 3","pages":"123-137"},"PeriodicalIF":3.8,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9517875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the genetic architecture of the CC and the genetic link with psychiatric disorders remains largely unclear. We investigated the genetic architectures of the volume of the CC and its subregions, and the genetic overlap with psychiatric disorders. Methods: We applied multivariate GWAS to genetic and T1-weighted MRI data of 40,894 individuals from the UK Biobank, aiming to boost genetic discovery and to assess the pleiotropic effects across volumes of the five subregions of the CC (posterior, mid posterior, central, mid anterior and anterior) obtained by FreeSurfer 7.1. Multivariate GWAS was run combining all subregions, co-varying for relevant variables. Gene-set enrichment analyses were performed using MAGMA. Linkage disequilibrium score regression (LDSC) was used to determine SNP-based heritability of total CC volume and volumes of its subregions as well as their genetic correlations with relevant psychiatric traits. Results: We identified 70 independent loci with distributed effects across the five subregions of the CC (p < 5 x 10-8). Additionally, we identified 33 significant loci in the anterior subregion, 23 in the mid anterior, 29 in the central, 7 in the mid posterior and 56 in the posterior subregion. Gene-set analysis revealed 156 significant genes contributing to volume of the CC subregions (p < 2.6 x 10-6). LDSC estimated the heritability of CC to (h2SNP=0.38, SE=0.03), and subregions ranging from 0.22 (SE=0.02) to 0.37 (SE=0.03). We found significant genetic correlations of total CC volume with bipolar disorder (BD, rg=-0.09, SE=0.03; p=5.9 x 10-3) and drinks consumed per week (rg=-0.09, SE=0.02; p=4.8 x 10-4), and volume of the mid anterior subregion with BD (rg=-0.12, SE=0.02; p=2.5 x 10-4), major depressive disorder (rg=-0.12, SE=0.04; p=3.6 x 10-3), drinks consumed per week (rg=-0.13, SE=0.04; p=1.8 x 10-3) and cannabis use (rg=-0.09, SE=0.03; p=8.4 x 10-3). Conclusions: Our results demonstrate that the CC has a polygenic architecture implicating multiple genes, and show that CC subregion volumes are heritable. We found distinct genetic factors are involved in the development of anterior and posterior subregions, consistent with their divergent functional specialization. Significant genetic correlation between volumes of the CC and bipolar disorder, drinks per week, major depressive disorder and cannabis consumption subregion volumes with psychiatric traits is noteworthy and deserving of further investigation.","PeriodicalId":7066,"journal":{"name":"Acta Neuropsychiatrica","volume":"1 1","pages":"1-21"},"PeriodicalIF":3.8,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41735974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MDD is characterised by activation of the immune-inflammatory response system (IRS) and the compensatory immunoregulatory system (CIRS), including deficits in T regulatory (Treg) cells. This study examines the number of cannabinoid type 1 (CB1) and type 2 (CB2) receptor bearing T/B lymphocytes in MDD, and the effects of in vitro cannabidiol (CBD) administration on CB1/CB2. Using flow cytometry, we determined the percentage of CD20+CB2+, CD3+CB2+, CD4+CB2+, CD8+CB2 and FoxP3+CB1+ cells in 19 healthy controls and 29 MDD patients in 5 conditions: baseline, stimulation with anti-CD3/CD28 with or without 0.1 mug/mL, 1.0 mug/mL or 10.0 mug/mL CBD. We found that CB2+ was significantly higher in CD20+ than CD3+ and CD4+, and CD8+ cells. Stimulation with anti-CD3/CD8 beads increases the number of CB2-bearing CD3+, CD4+, and CD8+ cells, as well as CB1-bearing FoxP3+ cells. There was an inverse association between the number of reduced CD4+CB2+ and IRS profiles, including M1 macrophage, T helper-(Th)-1 and Th-17 phenotypes. MDD is characterized by lowered basal FoxP3+CB1+% and higher CD20+CB2+%. 33.2% of the variance in the depression phenome (including severity of depression, anxiety, and current suicidal behaviors) is explained by CD20+CB2+% (positively) and CD3+CB2+% (inversely). All 5 immune cell populations were significantly increased by 10 mug/mL CBD administration. In conclusion, reductions in FoxP3+CB1+% and CD3+/CD4+CB2+% contribute to deficits in immune homeostasis in MDD, while increased CD20+CB2+% may contribute to the pathophysiology of MDD by activating T-independent humoral immunity.","PeriodicalId":7066,"journal":{"name":"Acta Neuropsychiatrica","volume":"1 1","pages":"1-40"},"PeriodicalIF":3.8,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49444265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
