CCL12  (趋化因子 CCL12)

CCL12 又称单核细胞趋化蛋白 5 (MCP-5),属于小鼠第 11 号染色体上的 CC 趋化因子簇。由于其在结构上与人类的 MCP-1最接近(氨基酸同源性 66%),有时也被称为 MCP-1 相关趋化因子。CCL12 是一种强效的外周血单核细胞趋化剂,可以吸引嗜酸性粒细胞、单核细胞和淋巴细胞但不吸引中性粒细胞的趋化因子。在外周血单个核细胞中诱导钙通量,但在纯化的小鼠嗜酸性粒细胞或中性粒细胞中不诱导钙通量。CCL12 通过 CCR2 发出信号的有效单核细胞活性趋化因子。参与过敏性炎症和宿主对病原体的反应,并可能在过敏性肺部炎症的早期阶段发挥关键作用[1][2]

CCL12, also known as monocyte chemotactic protein 5 (MCP-5), belongs to the CC chemokine cluster on mouse chromosome 11. CCL12 is a potent peripheral blood mononuclear cell chemokine that attracts eosinophils, monocytes and lymphocytes but not neutrophils. It induces calcium flux in peripheral blood mononuclear cells, but not in purified mouse eosinophils or neutrophils. CCL12 is a potent monocyte-active chemokine that signals through CCR2. Involved in allergic inflammation and host response to pathogens, and may play a key role in the early stages of allergic pulmonary inflammation[1][2].
