Template:PBB/6373 CXCL11（Template:Langx）化學式為：C368H618O99N106S6[1]，是一小分子的細胞因子屬於CXC趨化因子家族[2]，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)[2]。
表達[編輯]
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[2]。干擾素伽瑪和干擾素－b可以在單核細胞[2]，支氣管上皮細胞[3]，中性粒細胞[4]，角質形成細胞[5]，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[2][6][7]。CXCL11也可以結合到趨化因子受體CCR3上而阻止CCR3配體的結合[8]。
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[2]。
