T cell infiltration of the tumour is correlated with longer disease‐free survival in stage III cancer patients.35 In addition, CXCR3 and its ligands CXCL9 and CXCL10 are closely related to the TH1 immune response, and CXCR3 mediates the anti‐tumour response by recruiting into tumours NK cells, CD4‐positive Th1 cells and CD8‐positive cytotoxic T lymphocytes tumours. The gene discussed is CD4; the disease is neoplasm.
