摘要:

纤维化导致的器官结构破坏和功能减退乃至衰竭严重威胁人类健康及生命。巨噬细胞是存在于组织和器官中的重要免疫细胞。在转化生长因子β1(TGF-β1)、Toll样受体4(TLR4)/核因子κB(NF-κB)、Janus激酶(JAK)/信号换能器和转录激活器(STAT)、Notch信号通路、过氧化物酶体增殖物激活受体(PPAR)和环磷腺苷响应性元件结合蛋白(CREB)等众多因子及通路独自或相互串扰下,巨噬细胞可发生极化。在内脏器官纤维化中,单一或多种因子与通路构成的巨噬细胞极化信号网络是调节纤维化的重要机制之一。巨噬细胞极化后产生趋化因子和基质金属蛋白酶(MMP)等促纤维化相关因子,导致纤维化发生发展。目前国内外研究多聚焦于巨噬细胞在感染、肿瘤和纤维化中的作用,对巨噬细胞极化在纤维化中机制的研究较少。现对巨噬细胞极化涉及的相关通路进行综述,并总结巨噬细胞极化在器官纤维化中的机制,为纤维化的靶向治疗提供依据。

Abstract:

Organ structure destruction and functional decline leading to failure due to fibrosis pose severe threats to the human health and life. Macrophages are important immune cells present in various tissues and organs. Under the influence of numerous factors and pathways, such as transforming growth factor-β1(TGF-β1), Toll-like receptor 4(TLR4)/nuclear factor-κB(NF-κB), Janus kinase(JAK)/signal transducer and activator of transcription(STAT), Notch signaling pathway, peroxisome proliferator-activated receptor(PPAR), and cAMP response element-binding protein(CREB), the macrophages may undergo polarization. In visceral organ fibrosis, the macrophage polarization signaling network, composed of single or multiple factors and pathways, is one of the crucial mechanisms regulating fibrosis. After polarization, the macrophages produce the chemokines and matrix metalloproteinase(MMP), which are related to promoting fibrosis, leading to the occurrence and development of fibrosis. The current research conducted domestically and internationally mainly focuses on the roles of macrophages in infection, tumors, and fibrosis, with few summaries on the mechanisms of macrophage polarization in fibrosis. This review summarizes the pathways involved in macrophage polarization and the mechanisms of macrophage polarization in organ fibrosis, and provide the basis for the targeted therapy of fibrosis.

Key words: Fibrosis, Macrophage polarization, M1 macrophage, M2 macrophage, Signaling pathway
