Background: TCR gamma/delta
In humans, T cells expressing TCR gamma delta represents ~1-5% of total T cells in the peripheral blood but can comprise up to 50% of lymphoid cells in peripheral tissues like the intestines or dermis (3). The TCR gamma delta lineage arises from the double negative 3 (DN3) (CD44-,CD25-) stage of development where the cells receive strong TCR signals for gamma/delta selection (2). In contrast to alpha/beta T cells which are CD4+/CD8+, most gamma delta T cells are CD4-/CD8- (2). Gamma delta T cells produce different cytokines in response to varying degrees of signal received through the gamma delta TCR: a weaker signal induces interleukin (IL)-17, a moderate signal induces interferon (IFN)-gamma, and a strong signal stimulates IL-4 production (2,4). There are multiple gamma delta T cell subsets which are defined by the variable segments of the gamma and delta chain present after gene rearrangement (1,3,5). For example, Vgamma9Vdelta2 (Vgamma9Vdelta2) TCRs are expressed on the main subset of gamma delta T cells in human blood (1,3,5). Human gamma delta T cells expressing Vgamma9Vdelta2 TCR recognizes phosphoantigens that are released by tumor cells (3). The phosphoantigens bind butyrophilin (BTN) family members, such as BTN3A1/CD277, that are expressed on tumor cells and this interaction helps stimulate gamma delta T cell activation and tumor recognition (3). Considering their role in tumor recognition and killing, gamma delta T cells and the TCRs may be leveraged for cancer immunotherapies (3,4,6). Strategies for utilizing gamma delta T cells in immunotherapy include chimeric antigen receptor (CAR) transduction in gamma delta T cells, in vivo activation of gamma delta cells with anti-BTN3A1 monoclonal antibodies, or bispecific gamma delta T cell engagers (6).
