Eotaxin/CCL11  (趋化因子 CCL11)

CCL11 又称嗜酸性粒细胞趋化蛋白,eotaxin-1,是一种 CC 趋化因子家族小细胞因子,在人类中是由 17 号染色体上 CCL11基因编码的蛋白质。CCL11 在包括肠、淋巴结、胸腺、皮肤、心脏、肾脏和乳腺在内的多种组织中组成型表达。CCL11 是嗜酸性粒细胞、嗜碱性粒细胞和Th2 淋巴细胞的强效化学引诱剂。CCL11 可以通过与趋化因子受体包括CCR2、CCR3 和CCR5相结合,而发挥作用。其中介导 CCL11 生物学效应的主要受体是 CCR3,一种与异源三聚体 G 蛋白偶联的七跨膜受体 。Eotaxin-1/CCL11 最初与过敏反应期间嗜酸性粒细胞选择性募集到炎症部位有关,一旦与嗜酸性粒细胞表面表达的 CCR3 受体结合,eotaxin-1/CCL11 就会激活一系列细胞内信号级联反应,导致嗜酸性粒细胞募集到炎症部位。嗜酸性粒细胞是细胞毒性颗粒蛋白和生长因子的来源,它们分别负责与哮喘等多种疾病的病理生理学有关的组织损伤和重塑。例如分枝杆菌和血吸虫诱导的肉芽肿,参与缺血诱导的血管壁重塑。也有研究表明,CCL11 与衰老、神经发生和神经退行性变有关,能够影响神经祖细胞和小胶质细胞,作为一种诊断标志物[1][2]

CCL11, also known as eosinophil chemotactic protein, eotaxin-1, is a small cytokine of the CC chemokine family and in humans is a protein encoded by the CCL11 gene on chromosome 17. CCL11 is constitutively expressed in a variety of tissues including the intestine, lymph nodes, thymus, skin, heart, kidney and breast. CCL11 can act by binding to chemokine receptors including CCR2, CCR3 and CCR5. The primary receptor mediating the biological effects of CCL11 is CCR3, a seven-transmembrane receptor coupled to a heterotrimeric G protein. Eotaxin-1/CCL11 is initially associated with selective recruitment of eosinophils to sites of inflammation during allergic reactions. Once bound to CCR3 receptors expressed on the surface of eosinophils, eotaxin-1/CCL11 activates a series of intracellular signaling cascades that lead to eosinophil recruitment to sites of inflammation. Eosinophils are a source of cytotoxic granule proteins and growth factors responsible for tissue damage and remodeling, respectively, associated with the pathophysiology of a variety of diseases such as asthma. Examples include mycobacterial and schistosome-induced granulomas, which are involved in ischemia-induced remodeling of the vascular wall. It has also been shown that CCL11 is associated with aging, neurogenesis and neurodegeneration and is able to affect neural progenitor cells and microglia as a diagnostic marker[1][2].
