Although there are haematopoietic stem cells (HSCs) in umbilical cord blood (UCB), the number is limited. Thus, the purpose of this work was to investigate if endogenous hydrogen sulphide (H₂S) could encourage the ex vivo expansion of HSCs produced from UCB (UCB-HSCs). The CD34⁺ and CD34⁺CD38⁻ cells were enriched and separated by immunomagnetic beads. UCB-HSCs were treated with overexpression plasmids of β-synthase (CBS), cystathionine γ-lyase (CSE), 3-mercaptopyruvate sulphurtransferase (MPST) and/or stimulated with AG490 (JAK2/STAT3 inhibitor) for 4, 7 or 10 days, respectively. The content of H₂S in cells was detected using its assay kit. The proportion and quantity of CD34⁺, CD34⁺CD38⁻ and CXCR4⁺CD34⁺ cells as well as the ALDH1A1⁺CD34⁺ cells in CD34⁺ cells were detected by flow cytometry. qPCR was used to detect the expression of CD34, CXCR4 and ALDH1A1 in CD34⁺ cells. Western blot was used to detect the activation of the JAK2/STAT3 pathway in CD34⁺ cells. The results showed that endogenous H₂S enhanced the ex vivo expansion of CD34⁺ and CD34⁺CD38⁻ cells, upregulated the expression of CXCR4 and ALDH1A1 during ex vivo expansion of HSCs, and promoted the JAK2/STAT3 pathway in CD34⁺ cells. However, the aforementioned effects of endogenous H₂S were partially reversed by AG490. In conclusion, endogenous H₂S promotes the activation of the JAK2/STAT3 pathway to facilitate the ex vivo expansion of UCB-HSCs.</p>\u0000 </div>","PeriodicalId":13508,"journal":{"name":"Immunology","volume":"175 4","pages":"534-543"},"PeriodicalIF":4.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144127529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inhibitor of ER stress (4-PBA) significantly suppressed the activation of M1 macrophages and alleviated the renal fibrosis in the UUO mouse model.

Obesity induces metabolic dysfunction, meta inflammation and dysbiosis, which increase the prevalence of respiratory diseases and worsen immunopathology. The deficiency of IL-1α (IL-1α^−/−) induces deleterious lung monocytic inflammation and functional activation of the adaptive immune response mediated by T cells during <i>M. tuberculosis</i> infection in non-obese mice. Although iNOS and IFN-γ have been described as protective in experimental tuberculosis, using a model of obesity induced by high-fat diet, we show here an increase in iNOS-expressing interstitial macrophages positively correlated with <i>M. tuberculosis</i> numbers in the lungs of IL-1α^−/− animals, followed by increased frequency of IFN-γ and decreased frequency of IL-17-producing T cells, showing that IFN-γ and iNOS contribute to immunopathology and pulmonary damage.

While BCG is generally safe for full-term infants, its application in preterm infants is contentious due to their immature immune systems and heightened susceptibility to adverse effects. Preterm infants, particularly those with low birth weight, are at an elevated risk of severe complications, such as necrotizing enterocolitis (NEC), a life-threatening inflammatory condition of the intestines. NEC is characterised by dysregulated immune responses to microbial colonisation, with myeloid-derived suppressor cells (MDSCs) playing a crucial role in maintaining immune tolerance during early life. This study reveals that BCG vaccination significantly exacerbates NEC severity (<i>p</i> = 0.0048) by enhancing glycolysis and upregulating mTOR-HIF1α signalling in neonatal monocytic MDSCs (M-MDSCs), thereby impairing their immunosuppressive function. Pharmacological or genetic inhibition of mTOR-HIF1α signalling or glycolysis pathways restored M-MDSC function and mitigated NEC severity. These findings complement our previous work on BCG's effects on polymorphonuclear (PMN)-MDSCs and highlight the dual role of BCG: while it provides protective benefits in certain contexts, it may also increase NEC risk in preterm infants by disrupting MDSC-mediated immune tolerance.

While checkpoint blockade has emerged as a potent treatment option for numerous cancers, patient selection, long-term efficacy, and adverse effects still remain an issue. For these reasons, it is important to investigate other pathways that might lead to selective reactivation of the immune system. Co-stimulatory TNFRSF receptors, including 4-1BB and OX-40, have emerged as promising targets for reactivating exhausted T cells. However, their expression on exhausted peripheral and tumour-infiltrating lymphocytes (TILs) is not well characterised, particularly in cervical cancer (CC), which remains the leading cause of gynaecological cancer mortality in low- and middle-income countries. To investigate the expression of these receptors, PBMCs were collected from CC patients and healthy donors, along with TILs from tumour biopsies, and analysed using multiparametric flow cytometry. Our findings revealed an increased population of phenotypically exhausted (PD-1⁺TIGIT⁺) CD4⁺ and CD8⁺ T cells in TILs, and, to a lesser extent, in peripheral blood and from CC patients. These exhausted T cell subsets exhibited selective overexpression of 4-1BB and OX-40 compared to phenotypically non-exhausted cells (PD-1⁻TIGIT⁻). In TILs, 4-1BB was overexpressed 12.7-fold in CD8 cells with the exhausted phenotype, OX-40 was overexpressed 3.3-fold; in CD4 cells with the exhausted phenotype, the overexpression was 7.8× and 3.8× for 4-1BB and OX-40, respectively. CD8 and CD4 T cells that were PD-1 + TIGIT+ 4-1BB+ were 7.3× and 16× more likely to be found in the tumour versus peripheral blood. Additionally, subpopulations of PD-1^high T cells were significantly elevated in the tumour-infiltrating T cells and TIGIT expression was positively associated with PD-1 levels in peripheral patient CD8⁺ and CD4⁺ T cells, potentially indicating an advanced state of exhaustion.
