Therapeutic avenues for {gamma}{delta} T cells in cancer

January, 01, 2024 | Select Oncology Journal Articles

T cells are regarded as promising effector lymphocytes for next-generation cancer immunotherapies. In spite of being relatively rare in human peripheral blood, T cells are more abundant in epithelial tissues where many tumors develop, and have been shown to actively participate in anticancer immunity as cytotoxic cells or as “type 1” immune orchestrators. A major asset of T cells for tackling advanced cancers is their independence from antigen presentation via the major histocompatibility complex, which clearly sets them apart from conventional αβ T cells. Here we discuss the main therapeutic strategies based on human T cells. These include antibody-based bispecific engagers and adoptive cell therapies, either focused on the V1+ or V2+ T-cell subsets, which can be expanded selectively and differentiated or engineered to maximize their antitumor functions. We review the preclinical data that supports each of the therapeutic strategies under development; and summarize the clinical trials being pursued towards establishing T cell-based treatments for solid and hematological malignancies.
