Abstract

The evolution of macrophages has made them primordial for both development and immunity. Their functions range from the shaping of body plans to the ingestion and elimination of apoptotic cells and pathogens. Cytokines are small soluble proteins that confer instructions and mediate communication among immune and non-immune cells. A portfolio of cytokines is central to the role of macrophages as sentries of the innate immune system that mediate the transition from innate to adaptive immunity. In concert with other mediators, cytokines bias the fate of macrophages into a spectrum of inflammation-promoting "classically activated," to anti-inflammatory or "alternatively activated" macrophages. Deregulated cytokine secretion is implicated in several disease states ranging from chronic inflammation to allergy. Macrophages release cytokines via a series of beautifully orchestrated pathways that are spatiotemporally regulated. At the molecular level, these exocytic cytokine secretion pathways are coordinated by multi-protein complexes that guide cytokines from their point of synthesis to their ports of exit into the extracellular milieu. These trafficking proteins, many of which were discovered in yeast and commemorated in the 2013 Nobel Prize in Physiology or Medicine, coordinate the organelle fusion steps that are responsible for cytokine release. This review discusses the functions of cytokines secreted by macrophages, and summarizes what is known about their release mechanisms. This information will be used to delve into how selected pathogens subvert cytokine release for their own survival.

摘要

巨噬细胞的进化使它们成为发育和免疫的基础。它们的功能范围从塑造身体计划到吞噬和消除凋亡细胞和病原体。细胞因子是小分子可溶性蛋白,为免疫和非免疫细胞之间的指令和通信提供媒介。细胞因子组合是巨噬细胞作为先天免疫系统岗哨的核心作用,介导先天免疫向适应性免疫的转变。与其他介质一起,细胞因子使巨噬细胞的命运偏向于促进炎症的“经典激活”,或抗炎或“替代激活”的巨噬细胞。细胞因子分泌失调与多种疾病状态有关,从慢性炎症到过敏。巨噬细胞通过一系列精心协调的途径释放细胞因子,这些途径在时空上受到调节。在分子水平上,这些外排细胞因子分泌途径由多蛋白复合物协调,这些复合物将细胞因子从其合成点引导到其出口到细胞外环境的端口。这些运输蛋白中的许多是在酵母中发现的,并在 2013 年诺贝尔生理学或医学奖中得到纪念,它们协调负责细胞因子释放的细胞器融合步骤。这篇综述讨论了巨噬细胞分泌的细胞因子的功能,并总结了已知的它们释放机制。这些信息将用于深入研究某些病原体如何为了自身的生存而颠覆细胞因子的释放。
