In this study, we report that the multikinase inhibitor lenvatinib selectively reduced the number of CD206+CD163+ immunosuppressive macrophages in the tumor microenvironment (TME) and increased antitumor immunity. Longitudinal immunoprofiling was conducted with paired (pre- and posttreatment) tumor samples from patients with advanced gastric cancer who received first- or second-line combination therapy with lenvatinib and pembrolizumab in the EPOC1706 clinical trial. Patients with abundant CD206+CD163+ immunosuppressive macrophage infiltration exhibited favorable responses to combination therapy, accompanied by a significant posttreatment reduction in these cells. Although this immunosuppressive macrophage infiltration was associated with resistance to PD-1 blockade monotherapy, it predicted a response to combination treatment: 8 of the 9 patients with >440 CD206+CD163+ immunosuppressive macrophages/mm2 responded, whereas none of the 8 patients who received monotherapy responded. Mechanistically, lenvatinib inhibited platelet-derived growth factor receptor α (PDGFRα)/fibroblast growth factor receptor (FGFR)-dependent p38 mitogen-activated protein kinase (MAPK) and AKT signaling pathways in F4/80highCD11bint immunosuppressive macrophages, triggering endoplasmic reticulum stress and an unresolved unfolded protein response, resulting in their apoptosis. Furthermore, in multiple animal models, the therapeutic efficacy of the combination was observed in tumors with abundant immunosuppressive macrophages with activated PDGFR/FGFR-AKT/p38 MAPK signaling.

To overcome these barriers, we developed an intercellular adhesion molecule 1 (ICAM1)-specific chimeric costimulatory receptor (ICCR) engineered for expression in T cells to augment their activation. ICAM1 is broadly expressed across solid tumors and is further upregulated by IFNγ released during early T-cell engagement, creating a feed-forward loop that reinforces tumor recognition. ICCR engagement with ICAM1 triggered NF-κB signaling independently of TCR-peptide (p)/MHC engagement; however, full T-cell activation and cytotoxic function remained dependent on intact TCR signaling. In primary T cells, ICCR increased proliferation, cytokine production, and cytotoxicity, resulting in improved tumor control in two anaplastic thyroid cancer xenograft models treated with allogeneic or autologous ICCR-T cells. Mechanistically, ICCR strengthened tumor cell engagement, promoted selection and expansion of tumor-specific TCR clonotypes, and amplified downstream signaling pathways.

Through integrated analysis of single-cell RNA sequencing data from colorectal cancer clinical samples and pan-cancer datasets, combined with experimental validations, we first identified a prometastatic neuromedin B+ (NMB+)CXCL13+CD4+ T-cell subset and uncovered a mechanism by which this subset regulates tumor cell \"senescence-malignant transition,\" the NMB-NPSR1 axis.

Activation of NPSR1 triggered the Wnt signaling pathway and epithelial-mesenchymal transition, thereby enhancing cellular malignancy. This NPSR1+ senescent subpopulation also recruited endothelial cells and disrupted tight junction integrity, fostering a prometastatic microenvironment. As a proof-of-principle study, the combination of the NPSR1 inhibitor SHA68 and anti-PD-1 demonstrated remarkable antitumor effects using mouse models of colorectal cancer metastasis. Overall, this study uncovered the role of NMB+CXCL13+CD4+ T cells in promoting tumor cell senescence while influencing tumor metastasis, offering potential clinical implications for the diagnosis and treatment of metastatic colorectal cancer.</p>","PeriodicalId":9474,"journal":{"name":"Cancer immunology research","volume":" ","pages":"1150-1171"},"PeriodicalIF":7.9,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147763252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
