Wnt/β-catenin信号是一条进化上高度保守且极度复杂的发育信号通路,可调控胚胎发育、损伤修复以及多种人类疾病的发生、发展.大量证据表明,Wnt/β-catenin信号在肾脏早期发育中起关键作用,而在成年肾脏中则相对沉默.在多种肾脏病动物模型和人类肾脏疾病中它又被重新激活.急性肾损伤后Wnt/β-catenin的激活有助于受损肾小管的修复和再生.然而,该信号的持续激活与慢性肾脏疾病和肾纤维化的发生、发展密切相关.在本文中,我们对Wnt/β-catenin信号通路的组成及其转导机制,以及它在肾脏损伤后修复和纤维化过程中的作用进行较为系统的综述.深入阐明此信号通路的机制可能为将来防治肾脏病提供新的靶点和策略.

急性肾损伤(acute kidney injury,AKI)是指各种病理因素引起的肾功能短期内出现急速下降的临床综合征.在AKI发展过程中,具有重吸收和排泌功能的肾小管是损伤的重要靶点,极易因病理刺激发生细胞死亡,肾小管上皮细胞的丢失是肾功能受损的重要原因.近年来,多种细胞死亡方式被逐渐认识,研究者发现坏死性凋亡、焦亡与铁死亡等调节性细胞死亡(regulated cell death,RCD)方式都参与AKI的发生和发展.本文就各类RCD参与AKI进展的研究现状进行概述,试图加深对AKI发生机制的认识,并
