摘要: 传统意义上,人们将细胞死亡分为凋亡和坏死两类,而越来越多的研究结果表明坏死性凋亡是一种不同于坏死或凋亡的细胞死亡途径,并在多种疾病发病中发挥着重要作用。坏死性凋亡是调节坏死的一种形式,可以被死亡受体的配体激活,或者在无凋亡状态下被能够诱导死亡受体表达的刺激激活。死亡受体配体对坏死性凋亡激活需要RIP1激酶活性,其进一步介导RIP3和MLKL的激活。RIP3和MLKL是坏死性凋亡下游重要的调节子。RIP1激酶是坏死性凋亡通路中的关键药物靶点,通过坏死抑制素阻断RIP1活性,可以抑制坏死性凋亡的激活,并且在死亡受体配体存在的情况下使得细胞生存和增殖。本文将对坏死性凋亡与凋亡和坏死的区别、坏死性凋亡产生机制及其在肝炎以及其他肝病发病中的作用作一介绍,以期对肝病治疗药物新靶点的发现提供新思路。

Abstract: Traditionally cell death is divided into two categories,e.g. apoptosis and necrosis. But a growing body of research results show that the necrotic apoptosis is a kind of cell death different from necrosis and apoptosis,and plays an important role in a variety of diseases. Activation of necroptosis by ligands of death receptors requires the kinase activity of RIP1,which mediates the activation of RIP3 and MLKL,two critical downstream mediators of necroptosis. Blocking the kinase activity of RIP1,a key druggable target in the necroptosis pathway,by necrostatins inhibits the activation of necroptosis and allows cell survival and proliferation in the presence of death receptor ligands. In this review,we will discuss the difference between apoptosis,necrosis and necrotizing apoptosis,and we will summarizes the mechanism by which the necrotizing apoptosis occur in liver diseases.
