内质网应激介导肝细胞凋亡

Endoplasmic reticulum stress-mediated hepatocyte apoptosis

肝脏疾病组织学损伤,在细胞水平可分为凋亡和坏死,对肝细胞凋亡的研究无疑将成为治疗肝脏疾病及认识肝移植后组织再生的重要课题。文章将内质网应激与细胞凋亡的关系从内质网应激的作用功能、内质网应激对细胞凋亡的影响、肝细胞凋亡与相关疾病的关系等3方面进行分析。可以看出内质网应激是细胞的一种自我保护机制,但是过度的内质网应激会对细胞造成不可逆的损伤甚至促使凋亡。对于内质网应激与肝细胞凋亡的相关性以及相关程度还存在争论,有待进一步研究。随着对肝细胞疾病与内质网应激关系研究的不断深入,肝脏疾病的治疗将会更加有的放矢。

Apoptosis and necrosis are two forms of liver diseases at cell level. Research on hepatocyte apoptosis will become the important topic for treatment of liver disease and understanding of regeneration after liver transplantation. In this study, we analyzed the correlation between endoplasmic reticulum stress and cell apoptosis from effect and function of endoplasmic reticulum stress, influence of endoplasmic reticulum stress on cell apoptosis and association between hepatocyte apoptosis and related disease. Endoplasmic reticulum stress is a self-protection mechanism for cells, but too much endoplasmic reticulum stress will harm cells even cause apoptosis. It is still unclear about the relationship of the endoplasmic reticulum stress and hepatocyte apoptosis, so we need further researches. The progress of studies about the relations between hepatocyte diseases and endoplasmic reticulum stress will improve treatments of liver diseases,
