IL17A and neoplasm: Despite the expression of IL-17RA and IL-17RC on 4T1 TNBC tumor cells (Supplementary Fig. 1), 4T1 cells transduced with AdIL-17A and Addl showed similar growth kinetics in vitro (Fig. 2C), suggesting that IL-17A stimulation has a little direct effect on the growth of 4T1 TNBC cells.
