In contrast to conventional aβ T cells, (most) γδ T cells are not MHC-restricted. γδ T cells recognize and kill malignant cells through the T-cell receptor and activating NK receptors like NKG2D which recognizes stress-inducible cell surface ligands. The human Vγ9Vδ2 γδ T-cell receptor recognizes small pyrophosphates in the context of butyrophilin molecules. Such pyrophosphates are overproduced by many transformed cells, which renders tumor cells susceptible to γδ T-cell killing. Due to their MHC-independence, γδ T cells can be applied in cellular immunotherapy also across HLA barriers. On the other hand, γδ T cells are also subject to inhibitory mechanisms of the tumor micromilieu.
In this Special Issue, we will publish cutting edge papers dealing with various aspects of how γδ T cells interact with tumor cells, including translational perspectives for improving the clinical application of γδ T cells in immunotherapy. Both original contributions as well as focused reviews are welcome.
