EML4-ALK rearrangement creates a distinctive myeloid cell-dominant immunosuppressive microenvironment in lung cancer

Cancer Immunol Res. 2025 Jul 8. doi: 10.1158/2326-6066.CIR-24-0532. Online ahead of print. ABSTRACT Tyrosine kinase inhibitors (TKIs) are initially efficacious against anaplastic lymphoma kinase (ALK) fusion gene-positive lung adenocarcinoma (ALK+ LUAD), but acquired resistance inevitably occurs. Therefore, alternative treatment strategies are needed for TKI-resistant cases. Although the use of immune checkpoint inhibitors (ICIs) has improved … Read more

Vγ9Vδ2 T Cells Express an Antitumor Profile Associated with Anti-PD-(L)1 Responses and Activation Defects Restored by Anti-BTN3A in Triple-Negative Breast Cancer

Cancer Immunol Res. 2025 Jul 8. doi: 10.1158/2326-6066.CIR-24-1285. Online ahead of print. ABSTRACT Vγ9Vδ2 (TCRVγ9+ TCRVδ2+) T cells are promising immunotherapeutic targets with effective antitumor properties in both in vitro and preclinical models of triple-negative breast cancer (TNBC). However, no information regarding their potential role in the context of human TNBC progression and response to … Read more

Regulatory T cells poise the myeloid landscape after chemotherapy in lung tumors

Cancer Immunol Res. 2025 Jul 2. doi: 10.1158/2326-6066.CIR-25-0103. Online ahead of print. ABSTRACT Tumor-associated macrophages (TAMs) and regulatory T cells (Tregs) are major immune components of the tumor microenvironment, promoting tumor growth and limiting the efficacy of chemotherapy in almost all cancer indications. While Tregs are well known for their immune suppressive activity toward the … Read more

Harnessing Notch Signaling to Enhance the Generation and Functionality of Human Conventional Type I Dendritic Cells for Cancer Immunotherapy Applications

Cancer Immunol Res. 2025 Jul 2. doi: 10.1158/2326-6066.CIR-25-0034. Online ahead of print. ABSTRACT Dendritic cell (DC) based-vaccines remain the sole approved cancer vaccine. Despite their established safety and efficacy in numerous trials against cancers and infections, long-term clinical benefits have been modest. Most trials have employed DCs derived from blood monocytes (MoDC), but emerging evidence … Read more

Close Spatial Interactions between Cancer Cells and Cancer-Associated Fibroblasts Suppress Antitumor Immunity

Cancer Immunol Res. 2025 Jul 1. doi: 10.1158/2326-6066.CIR-24-1144. Online ahead of print. ABSTRACT Cancer-associated fibroblasts (CAFs) play immunosuppressive roles in the tumor microenvironment (TME). Specifically, they reportedly act as physical barriers preventing immune cell infiltration. However, the spatial relationships between CAFs and cancer cells in antitumor immunity remain unknown. In this study, we established three-dimensional … Read more

T cell receptor profiling of blood to detect lung cancer

Cancer Immunol Res. 2025 Jul 1. doi: 10.1158/2326-6066.CIR-24-1109. Online ahead of print. ABSTRACT The blood T cell receptor (TCR) repertoire broadly reflects current and lifetime immune responses against infectious pathogens and cancer, but the circulating T cell repertoire remains a largely untapped resource for cancer biomarker studies due to repertoire complexity and limited profiling data. … Read more

Bicistronic CAR-T Cell against BCMA and CD229 effectively controls myeloma even when BCMA expression is limited

Cancer Immunol Res. 2025 Jun 27. doi: 10.1158/2326-6066.CIR-24-1313. Online ahead of print. ABSTRACT Anti-BCMA CAR-T cell therapy has revolutionized the prognosis of relapsed / refractory multiple myeloma patients. Regrettably, despite unprecedented overall response rates achieved with this approach, most patients eventually relapse. One of the primary reasons for this is the complete loss or reduced … Read more

SF3B1K700E neoantigen is a CD8+ T-cell target shared across human myeloid neoplasms

Cancer Immunol Res. 2025 Jun 26. doi: 10.1158/2326-6066.CIR-24-0091. Online ahead of print. ABSTRACT Acquired mutations in spliceosome genes in early hematopoietic stem/progenitor cells are common events in myelodysplastic neoplasms (MDS) and related myeloid malignancies. Mutations in the spliceosome factor subunit B1 (SF3B1) gene occur in ≥20% of MDS cases at conserved hotspots and in early … Read more

GPC2-targeted CAR T cells engineered with NFAT-inducible membrane-tethered IL-15/IL-21 exhibit enhanced activity against neuroblastoma

Cancer Immunol Res. 2025 Jun 26. doi: 10.1158/2326-6066.CIR-24-0975. Online ahead of print. ABSTRACT Neuroblastoma (NB) is a highly aggressive childhood solid tumor with poor outcomes. Chimeric antigen receptor (CAR) T cells have shown limited efficacy in NB, with the best outcomes reported in patients with a low tumor burden, highlighting the need for further CAR … Read more
