In addition, γδ T cells can induce apoptosis through the expression of TNF-related apoptosis-inducing ligand (TRAIL) or FasL, highlighting their role in clearing tumor cells as well as activated immune cells during the resolution of inflammation (Dalton et al., 2004; Ponomarev and Dittel, 2005; Todaro et al., 2009). This evidence concerns the gene TNFSF10 and neoplasm.
