描述 CXCL10是一种在结构和功能上与CXCL9和CXCL11相关的ELR阴性趋化因子。CXCL10、CXCL9和CXCL11由单核细胞、巨噬细胞、成纤维细胞和上皮细胞在促炎细胞因子,特别是IFNγ刺激下产生和分泌。CXCL10通过与其受体CXCR3的结合来化学吸引CD4、CD8、NK和NKT细胞,CXCR3与CXCL9和CXCL11共享。此外,CXCL10在体内抑制肿瘤中的新生血管形成和伤口愈合。此外,CXCL10在体外对内皮细胞具有抗增殖作用,在体内具有血管抑制和抗肿瘤作用。已经提出CXCL10在内皮细胞中的抗增殖作用是不依赖于CXCR3的,并且它是通过GAG相互作用介导的。CXCL10还对大肠杆菌和单核细胞增多性李斯特菌以及炭疽杆菌的孢子和芽孢杆菌都具有抗菌活性。CXCL10的表达在许多炎症性疾病中强烈上调,包括关节炎、I型糖尿病、实验性自身免疫性脑脊髓炎、动脉粥样硬化、同种异体移植物排斥反应等。 CXCL10 is an ELR-negative chemokine structurally and functionally related to CXCL9 and CXCL11. CXCL10, CXCL9, and CXCL11 are produced and secreted by monocytes, macrophages, fibroblasts, and epithelial cells upon stimulation with proinflammatory cytokines, especially IFNγ. CXCL10 chemoattracts CD4, CD8, and NK and NKT cells through the binding to its receptor CXCR3, which is shared with CXCL9 and CXCL11. In addition, CXCL10 inhibits neovascularization in tumors and in wound healing in vivo. Also, CXCL10 has anti-proliferative effects on endothelial cells in vitro, and angiostatic and antitumor effects in vivo. It has been suggested that the anti-proliferative effect of CXCL10 in endothelial cells is CXCR3-independent and that it is mediated through GAG interaction. CXCL10 also possesses antimicrobial activity against E. coli and L. monocytogenes, and both the spore and bacillus forms of B. anthracis. CXCL10 expression is strongly upregulated in many inflammatory diseases, including arthritis, type I diabetes, experimental autoimmune encepahlomyelitis, atherosclerosis, allograft rejection, and others.

Antigen Details Structure Chemokine Distribution Interferon gamma-stimulated keratinocytes, monocytes, macrophages, fibroblasts, endothelial, and T cells.
Function CXCL10 chemoattracts CD4, Th1, CD8, and NK and NKT cells. CXCL10 is induced by inflammatory cytokines. NH2-terminal cleavage of CXCL10 by DPP-IV/CD26 impairs its chemoattracting capacity and CXCR3 signaling ability.
