The therapeutic mechanism of HSCT is believed to be mediated by the engraftment of hematopoietic stem cell progeny into the brain as microglia-like cells (MLCs). However, the engraftment of MLCs and their transcriptomic identity relative to endogenous microglia remain poorly understood. In this study, we used an autologous nonhuman primate (NHP) HSCT model to investigate the engraftment of MLCs after gene-modified autologous HSCT. We observed engraftment of gene-marked MLCs across a cohort of 5 NHPs. MLCs engrafted throughout diverse brain regions, adopted a homeostatic ramified morphology, and upregulated core microglial transcripts. We then used single-cell RNA sequencing to more rigorously evaluate the transcriptome of MLCs, revealing a border-associated macrophage-like phenotype. Our findings offer critical insights into the engraftment and behavior of MLCs after HSCT, laying the groundwork for their future use as a directed therapeutic option.</p>","PeriodicalId":9228,"journal":{"name":"Blood advances","volume":" ","pages":"6359-6365"},"PeriodicalIF":7.7,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13631576/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148276209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent genomic and epigenomic studies have refined this framework, distinguishing Epstein-Barr virus (EBV)-positive and EBV-negative BL molecular subtypes that cut across traditional clinical and epidemiological categories and exhibit distinct biological profiles. In high-income countries (HICs), BL is highly curable with intensive multiagent chemotherapy and antibody-based therapy. In contrast, survival in sub-Saharan Africa rarely exceeds 50%, reflecting diagnostic delays, limited access to effective treatment, and challenges in supportive care. This review summarizes the advances in BL epidemiology, molecular biology, diagnosis, and treatment, highlighting how genomic insights have identified novel biomarkers for earlier detection and monitoring, as well as potential targeted therapies with reduced toxicity. These advances present opportunities to develop scalable diagnostic tools and tailored therapeutic strategies to narrow survival disparities, particularly in resource-limited settings, where most patients occur, and among adults and patients with relapsed or refractory BL in HICs. We also outline key unanswered questions in BL epidemiology and pathogenesis, discuss opportunities for translational research, and emphasize the need for improved model systems to study therapeutic resistance to close the survival gap.</p>","PeriodicalId":9228,"journal":{"name":"Blood advances","volume":" ","pages":"6796-6811"},"PeriodicalIF":7.7,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13672841/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148444584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional metaphase karyotyping remains the diagnostic gold standard for detecting these abnormalities; however, its utility is limited by longer turnaround times, often delaying critical clinical management. Here, we present a long-read, low-coverage whole-genome sequencing (lcWGS) approach using Oxford Nanopore Technology as a rapid and scalable alternative for cytogenetic profiling. A total of 100 diagnostic AML samples were analyzed, comprising 50 retrospectively selected patients with known adverse-risk cytogenetics and 50 prospectively enrolled patients with clinically defined de novo AML. LcWGS demonstrated robust analytical performance, identifying chromosomal aberrations with 93% sensitivity, specificity, and overall accuracy, respectively. Complex karyotypes were reliably detected, with an area under the curve of 0.971. Reproducibility was validated through replicate sequencing at 2 independent laboratories (R = 0.99). LcWGS-derived estimates of clone size showed moderate correlation with conventional cytogenetic assessments (R = 0.54). Patients with complex karyotypes identified by lcWGS exhibited significantly shorter overall and relapse-free survival, closely mirroring outcomes defined by conventional karyotyping and underscoring the value of lcWGS for risk stratification. The median turnaround time from sample receipt to bioinformatics interpretation was ∼34 hours, enabling delivery of actionable karyotype results within 72 hours.

The protein C (PC) pathway is central to anticoagulant control, and common variants in thrombomodulin and endothelial PC receptor genes (THBD, PROCR) have been proposed as modulators. In 73 participants, we used standardized in vivo coagulation activation with recombinant activated factor VII (15 μg/kg) and measured thrombin markers and activated PC (APC) over 8 hours. Endothelial colony-forming cell-based ex vivo experiments were performed in 43 participants. In vivo, the ratio of APC area under the curve (AUC) to thrombin-antithrombin complex (TAT) AUC, which reflects the endogenous anticoagulant response relative to thrombin generation, provided the best model fit (adjusted R2 = 0.345). The APC response was lower in individuals with previous VTE (median, 0.13 vs 0.26) and PROCR 655A>G carriers (0.11 vs 0.26), but higher in factor V Leiden (FVL) carriers (0.32 vs 0.14) and THBD 1418C>T carriers (0.38 vs 0.13).

To address this, we analyzed 100 patients with t-MN by integrating clinical characteristics, prior treatment regimens, and genomic profiling. Somatic and germ line variants were identified using targeted next-generation sequencing (n = 33) or whole-exome sequencing (n = 67). Somatic abnormalities, including cytogenetic and/or molecular alterations, were detected in 89.8% of patients. Germ line variants were identified in 32.3% of patients, including mutations in cancer predisposition genes (19.8%) and myeloid disease-related genes (14.6%). Patient stratification by germ line landscape and gene category defined 2 prognostic scenarios and 3 subgroups with distinct clinical outcomes. Patients harboring germ line cancer predisposition variants were enriched for TP53 mutations and complex karyotypes and had an adverse prognosis. In contrast, patients with germ line myeloid-related variants and those without detectable germ line variants exhibited recurrent mutations in TET2, DNMT3A, SF3B1, SRSF2, RUNX1, and ASXL1, were associated with normal karyotypes, and had favorable outcomes. These findings underscore the importance of the germ line landscape in t-MN pathogenesis and support its incorporation into disease classification and risk stratification.
