引言多囊泡体(MVBs)是细胞内的重要细胞器,在细胞质量控制中扮演着关键角色。MVB膜通过内陷和切割形成腔内小泡(ILVs),负责分选蛋白质货物,这一过程按当今的理解需要ESCRT蛋白复合体消耗ATP来完成【1】。近些年研究显示,生物分子凝聚体是细胞 ...

内吞(endocytosis)是将细胞外的营养物质、细胞膜受体、脂类等通过细胞膜运输进入细胞的囊泡运输过程,大部分物质在内吞后会被运送到早期内体(early endosome)进行分选。约70-80%的内吞后的膜蛋白如受体、通道蛋白和转运蛋白等,会通过循环途径(recycling ...
自噬是真核细胞的高通量降解通路,参与细胞与机体的稳态维持。自噬异常与癌症、神经退行性病变等重大疾病相关。在植物中,自噬异常可造成育性与抗病抗逆性下降,而过表达自噬基因可提高植物耐盐性。自噬的核心是双层膜自噬体的从头生成,以及组装 ...
