Being deeply connected to signalling, cell dynamics, growth, regulation, and defence, endocytic processes are linked to almost all aspects of cell life and disease. In this review, we focus on endosomes in the classical endocytic pathway, and on the programme of changes that lead to the formation and maturation of late endosomes/multivesicular bodies. The maturation programme entails a dramatic transformation of these dynamic organelles disconnecting them functionally and spatially from early endosomes and preparing them for their unidirectional role as a feeder pathway to lysosomes.
作为与信号转导、细胞动态、生长、调控和防御密切相关的过程,内吞作用与细胞生命和疾病的几乎所有方面都有关联。在这篇综述中,我们聚焦于经典内吞途径中的内体,以及导致晚期内体/多泡体形成和成熟的变化方案。成熟方案涉及这些动态细胞器的剧烈转变,使它们在功能和空间上与早期内体分离,并使它们准备好作为溶酶体的单向进料途径发挥作用。
