The scarcity of validated biological markers for diagnosis, prediction, or treatment response impedes clinical progress. Emerging evidence implicates vascular dysregulation as a contributing factor in the pathophysiology of SB. This review critically synthesizes findings from clinical and preclinical studies to explore how disruptions in vascular homeostasis - including endothelial integrity, blood-brain barrier (BBB) permeability, platelet function, and microvascular flow - are associated with SB and related phenotypes. Epidemiological and genetic data further highlight shared vulnerability between SB and cardiovascular or neurovascular conditions. Additionally, individuals with SB exhibit signs of increased BBB permeability, platelet activation, nitric oxide dysregulation, altered kynurenine metabolism, elevated matrix metalloproteinase-9 activity, and white matter hyperintensities. These vascular disturbances may promote a pro-inflammatory and oxidative environment that impairs neuroplasticity, thereby heightening vulnerability to SB through cognitive and emotional dysregulation. Emerging molecular indicators of vascular dysfunction - such as claudin-5, thrombospondins, platelet-derived growth factors, and components of the nitric oxide system - show potential for improving diagnosis and guiding therapeutic development, though further replication is needed. While the current evidence remains preliminary and subject to limitations discussed herein, vascular dysfunction may serve as a dynamic indicator of both acute suicide risk and longer-term susceptibility. This review integrates vascular homeostasis into the broader biological framework of SB, alongside stress-response pathways, inflammation, and neural dysfunction, offering novel insights into SB pathophysiology and paving the way for developing targeted diagnostic tools and interventions.</p>","PeriodicalId":8918,"journal":{"name":"Biological Psychiatry","volume":" ","pages":""},"PeriodicalIF":9.6,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144494088","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, why clozapine is more effective than other antipsychotics in TRS remains unclear. This paper addresses this question. TRS patients show glutamate abnormalities, and clozapine has widespread effects on glutamate. However, these actions have not been proven different to those of other antipsychotics. Immune dysfunction is also reported in TRS, and clozapine has anti-inflammatory actions, but these have not been correlated with clinical improvement. Currently, there is much interest in muscarinic abnormalities in psychosis. Unlike most antipsychotics, clozapine has important effects on muscarinic receptors, particularly M1 and M4, and its major metabolite, N-desmethylclozapine, is a full agonist at M1. These effects are likely crucial to clozapine's effectiveness. In addition, clozapine's lower D2 receptor occupancy has been postulated to allow gradual resolution of dopamine receptor supersensitivity in the minority of patients with TRS who initially respond to antipsychotics but become resistant following long-term dopamine blockade. This hypothesis, however, remains controversial. Clozapine's multi-receptor profile enables it to have beneficial actions on the non-psychotic symptoms common in TRS: its ability to bind to histamine H1, serotonin 5-HT1A and GABA-B receptors offers an explanation for its anxiolytic actions while effects on 5-HT1A, 5-HT2A and 5-HT7 receptors likely underly its antidepressant properties. Clozapine shares these properties with olanzapine and quetiapine but its affinity for muscarinic receptors may be the mechanism by which it is more effective in TRS.</p>","PeriodicalId":8918,"journal":{"name":"Biological Psychiatry","volume":" ","pages":""},"PeriodicalIF":9.6,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144494089","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}

Some CNVs are highly penetrant for psychiatric disorders, where the total CNV impact to a neuropsychiatric phenotype is based on potential contribution from every gene it encompasses. However, it can be challenging to associate the typically numerous genes within the CNV to a mechanistic understanding of how brain dysfunction arises. Thus, open questions in CNV research are: how can the genes driving a phenotype be identified from all genes in a CNV and how can molecular mechanisms that lead to brain dysfunction with numerous potential candidate genes be determined? Until recently, these questions could be addressed only by highly laborious experimental setups that include screening individual and combinatorial knockouts of genes within a CNV. With the advance of single-cell and spatial omics, published high-resolution transcriptional data in space and time can help predict those genes that have the highest potential to drive a phenotype and thus pave the way for more efficient studies from genotype to phenotype. In this review, we discuss current progress in single-cell and spatial omics and propose a strategy for implementing these technologies in CNV research.","PeriodicalId":8918,"journal":{"name":"Biological Psychiatry","volume":"45 1","pages":""},"PeriodicalIF":10.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144335488","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}
