Finally, while this review was focused on IL‐17 and IFNγ production as hallmark effector functions of murine γδ T cells, one should highlight their versatility in mice and humans: besides being highly cytotoxic, as acknowledged for decades and currently being explored for cancer immunotherapy,144, 145 γδ T cells can provide a pleiotropy of factors, from antimicrobial peptides 146 to wound healing associated cytokines like amphiregulin.147. This evidence concerns the gene AREG and cancer.
