促进再生的环境因素在很大程度上是未知的。免疫系统和微生物组被认为在修复和再生结构中起作用,但它们之间的确切相互作用尚不清楚。在这里,我们评估了皮肤细菌在伤口愈合和伤口诱导毛囊新生(WIHN)中的功能,WIHN是一种罕见的成人器官发生模型。WIHN水平和干细胞标志物与细菌计数相关,在无菌(GF)中最低,在常规无特定病原体(SPF)中居中,在野生型小鼠中最高,即使是感染致病性金黄色葡萄球菌的小鼠。通过换笼或局部抗生素减少皮肤微生物群可降低WIHN。炎性细胞因子IL-1β和角质形成细胞依赖性IL-1 R-MyD 88信号传导对于细菌促进再生是必要且充分的。最后,在一项小型试验中,一种局部广谱抗生素也减缓了成年志愿者皮肤伤口的愈合。这些结果证明了IL-1β在控制形态发生中的作用,并支持重新考虑局部预防性抗生素常规应用的必要性。环境因素对皮肤再生的影响尚不清楚。Wang等人发现皮肤细菌通过需要IL 1 R/Myd 88的途径诱导IL 1 β信号传导并激活角质形成细胞,以刺激毛囊再生和伤口愈合。
Environmental factors that enhance regeneration are largely unknown. The immune system and microbiome are attributed roles in repairing and regenerating structure but their precise interplay is unclear. Here, we assessed the function of skin bacteria in wound healing and Wound Induced Hair follicle Neogenesis (WIHN), a rare adult organogenesis model. WIHN levels and stem cell markers correlate with bacterial counts, being lowest in germ-free (GF), intermediate in conventional specific pathogen free (SPF), and highest in wild-type mice, even those infected with pathogenic Staphylococcus aureus. Reducing skin microbiota via cage changes or topical antibiotics decreased WIHN. Inflammatory cytokine IL-1β and keratinocyte-dependent IL-1R-MyD88 signaling are necessary and sufficient for bacteria to promote regeneration. Finally, in a small trial, a topical broad-spectrum antibiotic also slowed skin wound healing in adult volunteers. These results demonstrate a role for IL-1β to control morphogenesis and support the need to reconsider routine applications of topical prophylactic antibiotics. The influence of environment factors on skin regeneration remains unclear. Wang et al find that skin bacteria induce IL1β signaling and activate keratinocytes via a pathway requiring IL1R/Myd88 to stimulate hair follicle regeneration and wound healing.
