For patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) or T-cell acute lymphoblastic leukemia (T-ALL), treatment options are limited, yet CART-cell therapies offer significant potential to address this unmet need. Here, we introduce a first-in-class CART-cell therapy targeting CD84, a novel antigen, for the treatment of R/R AML and T-ALL. CD84 is highly expressed on leukemic blasts, with limited expression on hematopoietic stem progenitor cells (HSPC), and is largely absent in healthy human tissues. Our second-generation CARTs targeting CD84 (CART84) demonstrate potent cytotoxicity against AML and T-ALL cells both in vitro and in vivo in patient-derived xenograft (PDX) models. Furthermore, CART84 eliminated primary leukemic blasts while exhibiting low cytotoxicity against CD34+ HSPC in vitro and in humanized mouse models in vivo, suggesting a low risk of myelotoxicity. These results support CD84 as a promising target for AML and T-ALL and provide the foundation for our upcoming first-in-human phase I/II clinical trial using CD84-directed CAR T cell therapy for patients with R/R AML and T-ALL (EudraCT 2024-519966-31-00).","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":"39 10","pages":"2432-2441"},"PeriodicalIF":13.4,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41375-025-02705-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144786490","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}

Human JAK2 V617F-mutated cell lines, 265 bone marrow biopsies (BMB) of two MPN cohorts, and 50 non-neoplastic BMB, revealed an intrinsic activation of IFN-γ signaling, which was confirmed by public RNA expression data. In vitro analysis of JAK2-mutated cell lines showed an activation of IFN-γ signaling pathway in the absence of IFN-γ in the cell supernatants. In addition, a heterogeneous, but increased expression of IFN-γ signaling components was found in BMB of JAK2-mutated samples with the highest expression in lymphocytes and monocytes, accompanied by increased tumor infiltrating lymphocytes (TIL). Unsupervised clustering identified a prognostic favorable cluster in both patient cohorts characterized by augmented IFN-γ signaling and TILs. This cluster was enriched with JAK2-mutated, JAK-inhibition naive MPN, mainly essential thrombocythemia and polycythemia vera with mild bone marrow fibrosis. Moreover, in silico data confirmed the link between JAK2 mutations and increased IFN-γ signaling. Multivariate Cox regression revealed TILs to be the strongest prognostic marker. In conclusion, JAK2-mutated MPN exhibit an intrinsic activation of IFN-γ signaling associated with changes in the BM TME and patients’ outcome.","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":"39 10","pages":"2391-2405"},"PeriodicalIF":13.4,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41375-025-02706-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144778510","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}

However, our knowledge of what molecular events are involved in pathogenesis is still missing. Here, we took advantage of this unique phenotype and screened whole transcriptome data from primary ATL cells to search for effective therapeutic targets. Glycoprotein A repetitions predominant (GARP) was identified as a novel tumor antigen in ATL. ATL cells overexpress GARP and release transforming growth factor-β (TGF-β). The GARP–TGF-β axis promotes cell proliferation of ATL cells and human T-cell leukemia virus type 1 (HTLV-1)-infected cells with changes in cell signaling activities and shaping of Treg gene expression patterns, but suppresses the activity of surrounding effector T-cells. Remarkably, this study has provided a breakthrough therapeutic concept that achieves the dual effect of direct tumor cell depletion and indirect immune activation by a single treatment targeting GARP. DS-1055a, an anti-GARP monoclonal antibody, selectively and effectively depleted malignant ATL cells via antibody-dependent cellular cytotoxicity, supporting the proof-of-concept in the preclinical study.

However, many initial responders relapse. We compared paired samples from subjects pre-therapy and then acquired resistance to daratumumab. We first used single-cell RNA sequencing and digital spatial profiler (DSP). The proportion of cytotoxic CD8-positive T-cells with an exhaustion phenotype and an IFN-γ signature increased in resistance compared with pre-therapy samples, whilst the proportion of NK-cells decreased and had an increased inhibitory phenotype. Transcription of CD38 in neoplastic plasma cells decreased. Numbers of immune cells in cancer centre defined by DSP were significantly decreased in parallel with an increased exhaustion signature. The acquired resistance signature and elevated PCM subset phenotype were associated with worse prognosis in 4 external cohorts (GSE24080, GSE136337, GSE57317, and coMMpass). Using single-cell regulatory network inference, we identified MYC regulation as a key activated factor for acquired resistance in neoplastic plasma cells by intersecting the top 20 upregulated regulons and upregulated genes in acquired resistance. Furthermore, data from in vitro and in vivo experiments indicate that IFN-γ secreted by cells of bone marrow immune ecosystem activates MYC, which correlates with acquired daratumumab resistance. Our data provide insights into acquired daratumumab resistance and suggest potential therapeutic strategies.","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":"39 10","pages":"2504-2515"},"PeriodicalIF":13.4,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41375-025-02712-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144756375","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}

The Sokal and EUTOS long-term survival scores were designed to predict CML-related mortality, but are also used to guide therapeutic choices, despite their poor performance for this purpose. A recent study proposed a refined predictive model of therapy failure specifically tailored for patients treated with imatinib and second-generation TKIs that showed promising results in a Chinese cohort. The present study evaluated the performance and applicability of this predictive model in a real-world, multicenter cohort from the French CML Observatory. The key differences identified between the Chinese and French cohorts (age, baseline hemoglobin levels, and treatment regimens) likely influenced the model performance. Specifically, the new model did not allow for discriminating risk groups effectively in the French cohort. However, the model reconstruction using this cohort identified other predictive variables (sex, leukocytosis, comorbidities, high-risk additional chromosomal abnormalities) that better stratified patients at risk of therapy failure. Our findings highlight the influence of demographic and clinical differences on predictive models and emphasize the need for local or population-specific tools to optimize risk stratification and therapeutic decision-making in CP-CML.","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":"39 10","pages":"2375-2383"},"PeriodicalIF":13.4,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41375-025-02703-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144756450","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}

To maximize therapeutic index, we identified selective/targetable BH3 dependences in individual TCL models and combined with CAR-37 T cells. We show that BH3 mimetics do not alter CD37 antigen binding capacity on TCL and have minimal effects on CAR-37 T-cell phenotype or function. In TCL models with dependence on MCL-1, combining CAR-37 T cells and the MCL-1 inhibitor AZD5991 increases anti-TCL response and prolongs survival of xenografted mice.

Subsequently, ZHX2 was proven to be critical for promoting DLBCL cell proliferation by inhibiting ferroptosis. Mechanistically, ZHX2 bound to the promoter region of the solute carrier family 3-member 2 (SLC3A2) gene through liquid-liquid phase separation (LLPS) and activated its function to negatively regulate ferroptosis. Furthermore, we constructed lipid nanoparticles ZHX2-siRNA@LNP targeting DLBCL, which effectively inhibited the growth of the tumors in vivo. In summary, our study indicated that the LLPS of ZHX2 protected DLBCL against ferroptosis through induction of SLC3A2, and disturbing it with ZHX2-siRNA@LNP could significantly repress DLBCL, providing a promising therapeutic strategy for DLBCL.","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":"39 10","pages":"2442-2451"},"PeriodicalIF":13.4,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41375-025-02718-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144736787","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}
