免疫系统由分布在整个生物体中的不同类型的细胞组成,以感知和响应病理情况,同时在生理条件下保持动态平衡。免疫细胞之间的细胞间通信对于协调有效的免疫反应是必不可少的,它涉及细胞接触依赖和独立的过程,确保旁观者和远程细胞之间的信息传递。有越来越多的证据表明细胞外小泡(EV)在细胞通讯中起着关键作用,这些结构正在成为免疫调节的重要媒介。在过去的十年中,EV被证明是包括microRNAs在内的遗传信息的有效载体,可以在细胞之间转移,并调节受体细胞上的基因表达和功能。在这里,我们综述了目前EV传递的microRNAs在细胞间功能转移的知识及其在免疫调节中的假定作用。
The immune system is composed of different cell types localized throughout the organism to sense and respond to pathological situations while maintaining homeostasis under physiological conditions. Intercellular communication between immune cells is essential to coordinate an effective immune response and involves both cell-contact dependent and independent processes that ensure the transfer of information between bystander and distant cells. There is a rapidly growing body of evidence on the pivotal role of extracellular vesicles (EVs) in cell communication and these structures are emerging as important mediators for immune modulation upon delivery of their molecular cargo. In the last decade, EVs have been shown to be efficient carriers of genetic information, including microRNAs, that can be transferred between cells and regulate gene expression and function on the recipient cell. Here we review the current knowledge of intercellular functional transfer of EV-delivered microRNAs and their putative role in immune regulation.
