Abstract

Foxp3-expressing regulatory T cells (Tregs) reside in tissues where they control inflammation and mediate tissue-specific functions. The skin of mice and humans contain a large number of Tregs; however, the mechanisms of how these cells function in skin remain largely unknown. In this article, we show that Tregs facilitate cutaneous wound healing. Highly activated Tregs accumulated in skin early after wounding, and specific ablation of these cells resulted in delayed wound re-epithelialization and kinetics of wound closure. Tregs in wounded skin attenuated IFN-γ production and proinflammatory macrophage accumulation. Upon wounding, Tregs induce expression of the epidermal growth factor receptor (EGFR). Lineage-specific deletion of EGFR in Tregs resulted in reduced Treg accumulation and activation in wounded skin, delayed wound closure, and increased proinflammatory macrophage accumulation. Taken together, our results reveal a novel role for Tregs in facilitating skin wound repair and suggest that they use the EGFR pathway to mediate these effects.

摘要

表达Foxp3的调节性T细胞(Tregs)存在于控制炎症并介导组织特异性功能的组织中。小鼠和人类的皮肤含有大量Tregs;然而,这些细胞在皮肤中发挥功能的机制在很大程度上仍不清楚。在本文中,我们表明Tregs促进皮肤伤口愈合。高度活化的Tregs在受伤后早期在皮肤中积累,特异性清除这些细胞会导致伤口再上皮化延迟和伤口闭合动力学改变。受伤皮肤中的Tregs减少了IFN-γ的产生和促炎性巨噬细胞的积累。受伤后,Tregs诱导表皮生长因子受体(EGFR)的表达。Tregs中EGFR的谱系特异性缺失导致受伤皮肤中Tregs的积累和活化减少、伤口闭合延迟以及促炎性巨噬细胞积累增加。综上所述,我们的结果揭示了Tregs在促进皮肤伤口修复中的新作用,并表明它们利用EGFR途径介导这些作用。
