[Abstract]  During the course of evolution, prokaryote and eukaryote cells have developed elegant and to some extent analogous strategies to communicate with each other and to adapt to their surrounding environment. Eukaryotic cells communicate with each other through direct interaction via juxtracrine signaling and/or by secreting soluble factors. These secreted factors can subsequently act on the cell itself (autocrine signaling) or interact with neighboring (paracrine signaling) and distant (endocrine signaling) cells. The transmission of signals between cells and tissues has been traditionally thought to be regulated by a protein-based signaling system. Typically, proteins destined for secretion into the extracellular milieu by exocytosis contain a canonical secretion-targeting sequence (Théry et ... [摘要]  在进化过程中,原核生物和真核生物细胞已经形成了优雅,在一定程度上类似的相互交流和适应周围环境的策略。真核生物细胞通过直接相互作用经Juxtracrine信号传导和/或通过分泌可溶性因子相互沟通。这些分泌的因子随后可以作用于细胞本身(自分泌信号传导)或与邻近的(旁分泌信号传导)和远处的(内分泌信号传导)细胞相互作用。传统上认为细胞和组织之间的信号传递受到基于蛋白质的信号传导系统的调节。通常,通过胞吐作用分泌到细胞外环境中的蛋白质含有典型的分泌靶向序列(Théry等,2002)。然而,具有非连续和刺激依赖性分泌的蛋白质,不含有经典分泌靶向序列的蛋白质,以及在细胞外环境(DNA,mRNA,肽,代谢物,miRNA和其他RNA)中可能过于不稳定的物质物种)可以以特定的方式分泌在小膜胞外囊泡(EV)中(Hagiwara等人,2014)。外来体代表直径为30-130nm的这些分泌的膜囊泡中的一大类(Cocucci等人,2009;Théry等人,2009; Kowal等人, >,et al。,2014),其形成在称为多泡体的内体隔室中的分泌细胞内。加载到外泌体中的分子以及细胞之间外来体转移的强度是随后调节受体细胞的重要参数。目前关于外泌体分泌及其在受体细胞中内化的知识仍不完整。已知外泌体的分泌强度根据细胞类型和其生理状态而变化(Garcia等人,2016)。此外,促进与细胞 - ...
