CXCL11
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
在白細胞,胰腺和肝臟中表達水平高,在胸腺,脾和肺有中等水平的表達,在小腸,胎盤和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
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
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]。
