The total number of all IL-17A–, IL-17F–, TIM-3–, and AREG-expressing Vγ4+ and Vγ6+ cells was increased in lungs of tumor-bearing mice when compared to tumor-free controls (Fig. 6 C), mirroring the increase of total cell numbers shown in Fig. 4 B. This evidence concerns the gene IL17F and neoplasm.
