CXCL10 and neoplasm: Surprisingly, CXCL10 (IP-10) and CXCL11 (I-TAC) were both present in significantly higher concentrations in the tumor tissue compare to unaffected mucosa (70±56 and 8.2±6.6 pg CXCL10/mg protein, respectively, p<0.01 and 672±442 and 211±161 pg CXCL11/mg protein, respectively, p<0.001) even though both CXCR3+ CD4+ and CD8+ T cells were present in significantly lower numbers in the tumor compared to the unaffected tissue.
