IL17A and neoplasm: For instance, in models of hepatocellular carcinoma and peritoneal B16 tumor, tumor‐infiltrating IL‐17+ Vγ6+ γδ T cells express low amounts of the antioxidant glutathione, which make them highly susceptible to ROS produced by tumor‐associated neutrophils.101 These recent insights of the effect of metabolic state of the tumor microenvironment on the promotion of pro‐ or antitumor immune cells require further investigation.
