In fact, RT sustains CD8 T-cell recruitment into the tumor by inducing the expression of several factors, including IFNα, CXCL9, CXCL10, and CXCL11, as well as promoting extravasation by upregulating ICAM-1 and E-selectin on endothelial cells [17,22,23]. The gene discussed is CXCL9; the disease is neoplasm.
