Initially after injury, the innate/proinflammatory and some aspects of the acquired immune response are up-regulated to maintain a defense against foreign pathogens, clear tissue debris present at the wound site, and orchestrate aspects of tissue remodeling, cell proliferation and angiogenic process, associated with the wound response. However, for proper wound healing to progress, this initial inflammatory response has to be regulated or shut down so as to allow for the reestablishment of matrix, recellularization, and tissue remodeling. Inability to properly resolve the extent of innate/acquired response at a site of injury can lead to poor wound healing, immune suppression, and recurrent infectious episodes. This review attempts to summarize information on regulatory mechanisms that are thought to be involved in controlling/resolving innate or acquired immune responses so as to provide a framework for use in thinking about the impact these processes and their manipulation may have on wound healing and its potential management.
受伤后最初阶段,先天性/促炎免疫反应以及获得性免疫反应的某些方面会上调,以抵御外来病原体,清除伤口部位的组织碎片,并协调与伤口反应相关的组织重塑、细胞增殖和血管生成过程。然而,为了使伤口正常愈合,这种初始炎症反应必须得到调节或终止,以便重新建立基质、细胞再填充和组织重塑。在损伤部位无法适当地解决先天性/获得性免疫反应的程度可能导致伤口愈合不良、免疫抑制和反复感染发作。本综述试图总结有关调控机制的信息,这些机制被认为参与控制/解决先天性或获得性免疫反应,从而提供一个框架,用于思考这些过程及其调控对伤口愈合及其潜在管理可能产生的影响。
