In tumor models, Tim3 on BATF3+CD103+ cDC1s suppresses the production of CXCL9, a chemokine critical for the recruitment of effector CD8+ T cells to the tumor microenvironment, and blockade of Tim3 enhances CXCL9 production and improves antitumor immunity122. This evidence concerns the gene CXCL9 and neoplasm.
