Some reports from the literature demonstrate that IL-17 production by Tc17 and Th17 cells favors the recruitment of neutrophils into different tissues such as the lung in a murine model of lethal influenza infection (44), the tumor in a model of murine melanoma (10) and tumor draining lymph nodes in a murine colon carcinoma model (45). This evidence concerns the gene IL17A and colon carcinoma.
