Interferon-stimulated T-cell Alpha Chemoattractant (I-TAC, CXCL11, interferon gamma-inducible protein-9, IP-9) is a cytokine that is chemotactic for activated T cells. Gene expression of I-TAC is mostly induced by IFN-γ and IFN-β, and to a lesser degree by IFN-α. I-TAC is highly expressed in peripheral blood leukocytes, pancreas and liver. I-TAC is also produced in moderate levels in thymus, spleen and lung. Low expression levels of I-TAC can also be found in small intestine, placenta, and prostate.
