We could reveal in this article that tumour cells bear all cytokine receptors IL-17R, -21R, -22R necessary to respond on the proinflammaory cytokines secreted by Th17 cells (except IL-26R, which we have not measured), so we propose that tumour cells can be massively influenced by surrounding tumour-infiltrating Th17 cells. This evidence concerns the gene IL17RA and neoplasm.
