Biogenesis of Fungal Extracellular Vesicles: What Do We Know?

So far, extracellular vesicles (EVs) have been described in 15 genera of fungi. They carry molecules that contribute to the interaction of fungal cells with the host. Although the number of studies on fungal EVs has increased, the mechanisms involved in their biogenesis are still poorly understood. The current knowledge of EV biogenesis shows us that they can originate both in the cytoplasm and at the plasma membrane. In this chapter, we will focus on these two cellular sites to review what is known about the biogenesis of fungal EVs.
