Abstract

Macrophages regulate cutaneous wound healing by immune surveillance, tissue repair and remodelling. The depletion of dermal macrophages during the early and middle stages of wound healing has a detrimental impact on wound closure, characterised by reduced vessel density, fibroblast and myofibroblast proliferation, delayed re-epithelization and abated post-healing fibrosis and scar formation. However, in some animal species, oral mucosa and foetal life, cutaneous wounds can heal normally and remain scarless without any involvement of macrophages. These paradoxical observations have created much controversy on macrophages' indispensable role in skin wound healing. Advanced knowledge gained by characterising macrophage subsets, their plasticity in switching phenotypes and molecular drivers provides new insights into their functional importance during cutaneous wound healing. In this review, we highlight the recent findings on skin macrophage subsets, their functional role in adult cutaneous wound healing and the potential benefits of targeting them for therapeutic use.

摘要

巨噬细胞通过免疫监视、组织修复和重塑来调节皮肤伤口愈合。在伤口愈合的早期和中期,真皮巨噬细胞的耗竭会对伤口闭合产生不利影响,其特征是血管密度降低、成纤维细胞和肌成纤维细胞增殖减少、再上皮化延迟以及愈合后纤维化和瘢痕形成减弱。然而,在某些动物物种、口腔黏膜和胎儿生命中,皮肤伤口可以正常愈合且不留瘢痕,而没有巨噬细胞的参与。这些矛盾的观察结果引发了关于巨噬细胞在皮肤伤口愈合中不可或缺作用的争议。通过对巨噬细胞亚群进行特征描述、表型转换的可塑性以及分子驱动因素的深入了解,为其在皮肤伤口愈合过程中的功能重要性提供了新的见解。在这篇综述中,我们强调了皮肤巨噬细胞亚群的最新发现,以及它们在成人皮肤伤口愈合中的功能作用,以及针对它们进行治疗用途的潜在益处。
