Extracellular vesicles mediate interactions between cells, tissues, and organisms. They play significant roles in arthropod physiology and vector-pathogen interactions and are potential targets for controlling arthropods and mitigating zoonotic pathogens. This symposium will explore the diversity of roles of extracellular vesicles in arthropods and highlight areas for further exploration.
