Abstract

Several members of the chemokine family are involved in regulation of fibrosis. This review manuscript discusses the role of the chemokines in the pathogenesis of myocardial fibrosis. The CC chemokine CCL2 exerts fibrogenic actions through recruitment and activation of monocytes and macrophages expressing its receptor, CCR2. Other CC chemokines may also contribute to fibrotic remodeling by recruiting subsets of fibrogenic macrophages. CXC chemokines containing the ELR motif may exert pro-fibrotic actions, through recruitment of activated neutrophils and subsequent formation of neutrophil extracellular traps (NETs), or via activation of fibrogenic monocytes. CXCL12 has also been suggested to exert fibrogenic actions through effects on fibroblasts and immune cells. In contrast, the CXCR3 ligand CXCL10 was found to reduce cardiac fibrosis, inhibiting fibroblast migration. Chemokines are critical links between inflammation and fibrosis in myocardial disease and may be promising therapeutic targets for patients with heart failure accompanied by prominent inflammation and fibrosis.

摘要

趋化因子家族的几个成员参与纤维化的调节。这篇综述手稿讨论了趋化因子在心肌纤维化发病机制中的作用。CC趋化因子CCL2通过募集和激活表达其受体CCR2的单核细胞和巨噬细胞发挥促纤维化作用。其他CC趋化因子也可能通过募集促纤维化巨噬细胞亚群促进纤维化重塑。含有ELR基序的CXC趋化因子可能通过募集活化的中性粒细胞并随后形成中性粒细胞胞外陷阱(NETs),或通过激活促纤维化单核细胞发挥促纤维化作用。CXCL12也被认为通过对成纤维细胞和免疫细胞的作用发挥促纤维化作用。相比之下,发现CXCR3配体CXCL10可减少心脏纤维化,抑制成纤维细胞迁移。趋化因子是心肌疾病中炎症和纤维化之间的关键联系,对于伴有明显炎症和纤维化的心力衰竭患者可能是有前景的治疗靶点。
