Preoperative chemotherapy with FOLFOX or with FOLFOX plus Avastin does not lower blood and hepatic MAIT cell frequencies. PBMCs (a), tumor-free, non-parenchymal hepatic mononuclear cells (b) and hepatic tumor-infiltrating mononuclear cells (c) were isolated from CRLM patients who had received no chemotherapy (filled triangles), FOLFOX (filled circles) or FOLFOX plus Avastin (open squares) before they underwent liver resection surgery. The percentage of MAIT cells in each cell population was determined by flow cytometry. Error bars represent SEM
