Chimeric antigen receptor (CAR)-T cell therapy holds great promise in treating B cell lymphoma and multiple myeloma.

Subsequently, we explored the advantages of targeting two antigens through the pooling of these CAR-T cells. In instances where target antigen expression was low (as determined by flow cytometry), dual targeting of TAG-72 and CD30 was able to elicit cytotoxic function.Conclusion: These findings define TAG-72 and CD30-targeting CAR-T cells as a promising strategy against T cell malignancies and highlight the potential of dual or combination CAR-T cell therapies for this aggressive disease.","PeriodicalId":13387,"journal":{"name":"Immunological Investigations","volume":" ","pages":"1-22"},"PeriodicalIF":2.4,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144759993","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}

Expression of FOXM1 and S1PR1 in mouse liver tissues or KCs was determined using RT-qPCR, immunofluorescence, or western blot assays. Loss- or gain-of-function assays of FOXM1 and S1PR1 were performed, followed by histopathological staining of the liver tissues, examination of the inflammatory cytokines, and assessment of macrophage phenotype.Results: FOXM1 exhibited heightened expression in the mouse liver tissues and KCs in AH models. Silencing FOXM1 reduced pathological injury, hepatic steatosis, alanine aminotransferase and aspartate aminotransferase levels, inflammatory cytokine production, and pro-inflammatory (M1) polarization markers of macrophages. This condition also alleviated M1 polarization of KCs in vitro. FOXM1 promoted transcription and expression of S1PR1 by binding to its promoter. The additional upregulation of S1PR1, in the presence of FOXM1, rescued M1 skewing of macrophages both in vitro and in vivo, thus aggravating inflammatory responses.Conclusion: This study identifies that FOXM1-mediated transcriptional upregulation of S1PR1 promotes pro-inflammatory activation of macrophages and augments liver injury in AH.","PeriodicalId":13387,"journal":{"name":"Immunological Investigations","volume":" ","pages":"824-843"},"PeriodicalIF":2.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144119567","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}
