摘 要：摘 要：Necroptosis 是一种可调控的细胞程序性坏死途径，它具有与不可调控性细胞坏死相同的形态学特征。Necroptosis 是caspase 非依赖的。当细胞凋亡被阻断时，necroptosis 信号通路由死亡结构域激活启动，其中RIP1 的活化是necroptosis 的关键步骤，该步骤可被necrostatin-1 特异性抑制。近期研究表明，necroptosis 在缺血性损伤、神经退行性疾病、恶性肿瘤、病毒感染和免疫性疾病等多种疾病的病理生理过程中起重要作用，有望作为药物开发的新靶点。对necroptosis 的发现历程、信号通路及其在疾病病理生理机制中的作用和靶向necroptosis 的治疗等四个方面进行综述。

Abstract: Abstract: Necroptosis is a specialized pathway of programmed necrosis induced by the activation of death domain (DD) under conditions when apoptosis execution is prevented. Necroptosis is caspase-independent， mediated by receptor-interacting protein 1 (RIP1) activity and inhibited by necrostatin-1 (Nec-1). Although it occurs under regulated conditions， necroptosis is characterized by the same morphological features as unregulated necrosis. In recent years， necroptosis has been found playing a significant role in multiple pathophysiologic processes. Targeting necroptosis pathway provides a new strategy for treatment of multiple human diseases involving ischemic injury， neurodegeneration disease， malignant tumor， virus infection and autoimmune disease. This review includes four parts: the discovery of necroptosis; the mechanism and signal pathway of necroptosis; the role that necroptosis plays in pathophysiologic processes of several diseases; the necroptosis targeted therapies.
Key words: necroptosis; signal pathway; pathophysiologic mechanism; targeted therapy
