CXCL11(C-X-C motif chemokine ligand 11)是一种趋化因子(chemokine),属于CXC趋化因子家族,该家族成员通常含有C-X-C(半胱氨酸-其他氨基酸-半胱氨酸)结构域,主要功能是招募免疫细胞(如T细胞和自然杀伤细胞)到炎症或感染部位。CXCL11通过与受体CXCR3(C-X-C chemokine receptor type 3)结合发挥作用,激活下游信号通路,调控免疫细胞的迁移和活化。CXCL11在抗病毒和抗肿瘤免疫中起重要作用,尤其在干扰素(IFN-γ)刺激下表达显著上调。CXCL11的生物学功能包括促进Th1型免疫反应(一种以干扰素和白细胞介素-2为主的免疫反应)、抑制血管生成(angiogenesis,新血管的形成)以及直接抑制某些肿瘤细胞的生长。其主要作用位点包括炎症部位、肿瘤微环境和感染组织。CXCL11基因突变可能导致其表达或功能异常,影响免疫细胞的招募和抗肿瘤反应,与自身免疫疾病(如类风湿性关节炎)、慢性炎症和癌症(如黑色素瘤、乳腺癌)的发生发展相关。CXCL11过表达可能增强抗肿瘤免疫反应,但过度招募免疫细胞也可能导致组织损伤或自身免疫疾病;而降低表达则可能削弱免疫监视功能,增加感染或肿瘤风险。CXCL11属于CXC趋化因子家族,该家族成员共性是通过CXCR受体介导免疫细胞迁移,参与炎症、感染和肿瘤免疫调控。目前中文术语“趋化因子”是对“chemokine”的通用翻译,无显著争议。
Chemokines are a group of small (approximately 8 to 14 kD), mostly basic, structurally related molecules that regulate cell trafficking of various types of leukocytes through interactions with a subset of 7-transmembrane, G protein-coupled receptors. Chemokines also play fundamental roles in the development, homeostasis, and function of the immune system, and they have effects on cells of the central nervous system as well as on endothelial cells involved in angiogenesis or angiostasis. Chemokines are divided into 2 major subfamilies, CXC and CC. This antimicrobial gene is a CXC member of the chemokine superfamily. Its encoded protein induces a chemotactic response in activated T-cells and is the dominant ligand for CXC receptor-3. The gene encoding this protein contains 4 exons and at least three polyadenylation signals which might reflect cell-specific regulation of expression. IFN-gamma is a potent inducer of transcription of this gene. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2014]
趋化因子是一组调节通过交互各类白细胞的细胞的运输7-跨膜,G蛋白偶联受体的一个子集的小(约8至14 kD的),主要是基本的,结构相关的分子。趋化因子在发育,稳态和免疫系统的功能也发挥基本作用,并且它们对中枢神经系统的细胞,以及对涉及血管发生或angiostasis内皮细胞的影响。趋化因子主要分为两大亚科,CXC和CC。此抗微生物基因是趋化因子超家族的CXC构件。其编码的蛋白质诱导活化的T细胞趋??化反应,是CXC受体3的主导配体。编码基因此蛋白含有4个外显子和至少三个聚腺苷酸化信号,这可能反映了表达的细胞特异性调节。的IFN-γ是该基因的转录的有效诱导。已发现该基因编码不同亚型的两个转录变异体。 [由RefSeq的,2014年10月提供]
