Abstract:
Extracellular vesicles are a group of endogenous nano-vesicles that carry host- and pathogen-derived proteins, nucleic acids and lipids. They can be produced by most types of cells and some pathogens, and play important roles in cell-to-cell communication. After pathogen infection, extracellular vesicles participate in the process of immune regulation by the pathophysiological changes mediated by spreading host- or pathogen-derived molecules. Here, we summarized the functions and mechanisms of extracellular vesicles in the pathogenic process of bacteria, viruses, fungi and some other pathogens, including promoting the transmission and replication of pathogens, changing the antigenicity and infectivity of pathogens through material transport, and affecting the immune response in human body.
Insights
Extracellular vesicles (EVs) are nano-sized vesicles involved in cell communication. This study reviews how EVs contribute to pathogen infections by spreading molecules and altering immune responses.
Area of Science:
- Microbiology and Immunology
- Cell Biology
- Nanotechnology
Background:
- Extracellular vesicles (EVs) are endogenous nano-vesicles produced by cells and some pathogens.
- EVs mediate intercellular communication by transporting proteins, nucleic acids, and lipids.
- Following infection, EVs play a role in immune regulation through molecular exchange.
Purpose of the Study:
- To summarize the functions and mechanisms of extracellular vesicles in pathogenic processes.
- To explore the role of EVs in infections caused by bacteria, viruses, and fungi.
Main Methods:
- Literature review and synthesis of existing research on extracellular vesicles in pathogenesis.
- Analysis of mechanisms by which EVs influence pathogen transmission, replication, and host immunity.
Main Results:
- Extracellular vesicles promote pathogen transmission and replication.
- EVs alter pathogen antigenicity and infectivity via material transport.
- EVs significantly impact host immune responses during infection.
Conclusions:
- Extracellular vesicles are key mediators in the pathogenesis of various infections.
- Understanding EV functions offers insights into novel therapeutic strategies against pathogens.
