Abstract

The increasing global burden of cancer necessitates innovative therapeutic strategies. Cell therapy represents a major breakthrough in oncology, evolving rapidly from the successful application of chimeric antigen receptor T (CAR-T) cells in hematologic malignancies to a multiplatform landscape characterized by the concurrent development of diverse strategies. Current research focuses on T cell receptor-engineered T (TCR-T) cells, tumor-infiltrating lymphocytes (TILs), gamma delta (γδ) T cells, CAR-natural killer (CAR-NK) cells, CAR-macrophages (CAR-Ms), and various strategies based on dendritic cells (DCs), B cells, and stem cells. The translational paradigm is expanding from the relatively mature field of hematologic malignancies to the more prevalent and mechanistically complex domain of solid tumors. In recent years, this field has exhibited a clear trend toward expansion from autologous therapies to allogeneic "off-the-shelf" platforms. Approaches such as CAR-NK and CAR-natural killer T (CAR-NKT) cell therapies exhibit significant clinical potential because of their low immunogenicity and reduced risk of graft-versus-host disease (GvHD). Concurrently, in vivo engineering technologies that directly deliver CAR genes in situ are emerging as promising approaches to lower costs and simplify manufacturing by bypassing complex ex vivo procedures. This review systematically outlines recent advances in these strategies, focusing on their mechanisms of action, target antigens, and clinical translation. Despite progress, formidable challenges remain, including tumor heterogeneity, the immunosuppressive tumor microenvironment (TME), and therapy-related toxicity. To address these challenges, future research will focus on novel target discovery, enhanced toxicity management, and scalable manufacturing processes. The integration of multidisciplinary technologies, such as multiomics analysis, artificial intelligence, and synthetic biology, will advance cell therapies toward safer, more effective, and widely accessible applications.
