CXCL11(英語:Chemokine (C-X-C motif) ligand 11)是一小分子的細胞因子屬於CXC趨化因子家族[1],又被稱作「干擾素誘導的T細胞a趨化因子」(Interferon-inducible T-cell alpha chemoattractant (I-TAC)[1]


表達[編輯]

白細胞胰腺肝臟中表達水平高,在胸腺有中等水平的表達,在小腸胎盤前列腺中表達水平低[1]干擾素伽瑪和干擾素-b可以在單核細胞[1],支氣管上皮細胞[2]中性粒細胞[3],角質形成細胞[4],和內皮細胞誘導CXCL11的表達。


受體[編輯]

CXCL11結合趨化因子受體CXCR3而起其細胞趨化作用[1][5][6]。CXCL11也可以結合到趨化因子受體CCR3上而阻止CCR3配體的結合[7]


功能[編輯]

CXCL11對活化的T細胞,中性粒細胞和單核細胞有細胞趨化作用[1]
