日前,国际学术权威刊物自然出版集团旗下子刊《Nature Communications》杂志上在线发表了清华大学伯克利深圳学院(TBSI)精准医疗与健康研究中心、清华大学深圳研究生院生命与健康学部吴耀炯教授题为“巨噬细胞通过AKT/β-catenin信号通路激活毛囊干细胞促进再生”(Macrophages induce AKT/β-catenin-dependent Lgr5+ stem cell activation and hair follicle regeneration through TNF)的研究论文。论文通过分子生物学、基因工程学和生物信息学方法,揭示了巨噬细胞-TNF诱导的Lgr5+毛囊干细胞Akt /β-catenin(β链蛋白)信号在皮肤损伤后毛囊再生中的关键作用。清华大学深圳研究生院生命与健康学部博士后王旭升,清华-伯克利深圳学院(TBSI)博士生陈海燕,清华大学深圳研究生院生命与健康学部博士生田瑞云为该文章的共同第一作者,吴耀炯教授为该文章的通讯作者。

皮肤干细胞具有再生毛囊等表皮附属器官的潜力,然而它们受损而失去时却往往不能被再生。因此,人们关注皮肤受到损伤时皮肤干细胞是如何反应的。本研究揭示,皮肤损伤时巨噬细胞分泌一种称为TNF的因子,它通过介导Akt/β链蛋白信号,激活Lgr5+毛囊干细胞;人为激活Akt/(β链蛋白)信号能够促进毛囊再生。本研究为研究促进毛囊和皮肤再生的方法奠定了基础。
