Extracellular vesicles (EVs) are membrane-enclosed nanometer-scale particles and have been discovered in nearly all kingdoms of life as a form of cellular communication across different cells and between interacting organisms. They can transport biological materials such as RNAs, proteins and metabolites. It should be noted that research on EVs has primarily focused on EV-mediated intra-organismal transport in mammals. However, the overall molecular content and functions of EVs in other kingdoms remain largely unknown. This chapter will also highlight on recent advances in EV-mediated communications in parasite–host interactions and report on the presence of EVs in insects and their potential role in systemic RNA interference (RNAi) in insects.

摘要

Extracellular vesicles (EVs) are membrane-enclosed nanometer-scale particles and have been discovered in nearly all kingdoms of life as a form of cellular communication across different cells and between interacting organisms. They can transport biological materials such as RNAs, proteins and metabolites. It should be noted that research on EVs has primarily focused on EV-mediated intra-organismal transport in mammals. However, the overall molecular content and functions of EVs in other kingdoms remain largely unknown. This chapter will also highlight on recent advances in EV-mediated communications in parasite–host interactions and report on the presence of EVs in insects and their potential role in systemic RNA interference (RNAi) in insects.
