In this prospective study, 200 patients undergoing ICI therapy were enrolled, of whom 59 underwent longitudinal metabolomic profiling at baseline, three months, and six months. Thirty-two patients who developed irAE were compared to 27 age- and sex-matched individuals without irAE.

Treatment with CAR-T cells has produced remarkable clinical responses, especially in cases of relapsed and refractory leukemia and lymphoma. However, CAR-T cell therapy still presents several limitations, including some safety concerns related to neurotoxicity and aggressive inflammatory responses. As an alternative to T-cells, natural killer (NK) cells have been developed as an attractive option for efficient cancer immunotherapy. As they do not express T cell receptor (TCR), NK cell-based therapies are not associated with cytokine release syndrome (CRS) or graft versus host disease (GvHD), which enables a safer therapy and the ability to generate an allogeneic \"off-the-shelf\" product. Despite the innate cytotoxic activity of NK cells against malignant cells, the therapeutic application of unmodified NK cells has been compromised by the inhibitory tumor microenvironment (TME), which is responsible for poor cell expansion, inactivation, insufficient tumor infiltration, and limited in vivo persistence, leading to the dysfunction of NK cells after infusion. Advances in the genetic modification of NK cells can address some of these limitations and improve their therapeutic efficacy. In this review, we describe the advances in the development of engineered NK cells for cancer immunotherapy.

However, their effectiveness against solid tumors is limited by challenges such as antigen escape, suppression by the metabolically hostile tumor microenvironment (TME), and manufacturing difficulties. γδ T cells are unconventional T cells with innate tumor-targeting capabilities independent of MHC class I, making them an emerging candidate for allogeneic cell therapy. While the Vδ1 T cell subset has shown promising anti-tumor killing their clinical application has been hindered by difficulties in achieving robust expansion for therapeutic use. Here, we evaluated the potential of K562 feeder cells expressing membrane-bound IL-21 (K562-mb-IL-21) to expand and activate γδ T cells from peripheral blood. Our findings show that this method preferentially expands Vδ1 T cells, resulting in an activated phenotype characterized by enhanced expression of NK cell activation receptors, innate cytotoxicity against breast and ovarian cancer cells, and sustained metabolic function in patient-derived ascites TME. When engineered with a CAR, Vδ1 T cells exhibited further enhanced anti-tumor efficacy in an immunodeficient NRG xenograft model of human ovarian cancer. These findings highlight K562-mb-IL-21 expanded peripheral blood Vδ1 T cells as a promising 'off-the-shelf' allogeneic therapy for solid tumors.</p>","PeriodicalId":48714,"journal":{"name":"Oncoimmunology","volume":"14 1","pages":"2562210"},"PeriodicalIF":6.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12477882/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145139060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
