The failure to resolve inflammation underpins to several prevalent diseases, like atherosclerosis, and so identifying ways to boost resolution is unmet clinical needs. The resolution of inflammation is governed by several factors such as specialized pro-resolving mediators (SPMs) that counter-regulate pro-inflammatory pathways and promote tissue repair without compromising host defense. A major function of nearly all SPMs is to enhance the clearance of dead cells or efferocytosis. As such, phagocytes, such as macrophages, are essential cellular players in the resolution of inflammation because of their ability to rapidly and efficiently clear dead cells. This review highlights the role of SPMs in the clearance of apoptotic and necroptotic cells and offers insights into how targeting efferocytosis may provide new treatments for non-resolving diseases, like atherosclerosis.
炎症反应无法消除是导致几种常见疾病(如动脉粥样硬化)的根本原因,因此,寻找增强炎症消退的方法是当前临床尚未满足的需求。炎症消退受到多种因素的调控,如专门的促解决介质(SPM),它们可以拮抗促炎途径并促进组织修复,同时不损害宿主防御。几乎所有 SPM 的主要功能之一是增强清除死亡细胞或噬作用。因此,吞噬细胞(如巨噬细胞)在炎症消退中是至关重要的细胞参与者,因为它们能够迅速有效地清除死亡细胞。本文重点介绍了 SPM 在清除凋亡和坏死细胞中的作用,并深入探讨了靶向噬作用是否可能为非解决性疾病(如动脉粥样硬化)提供新的治疗方法。
