Extracellular vesicles (EVs) are produced by all domains of life. In fungi, these structures were first described in and, since then, they were characterized in several pathogenic and non-pathogenic fungal species. Cryptococcal EVs participate in the export of virulence factors that directly impact the -host interaction. Our knowledge of the biogenesis and pathogenic roles of EVs is still limited, but recent methodological and scientific advances have improved our understanding of how cryptococcal EVs participate in both physiological and pathogenic events. In this review, we will discuss the importance of cryptococcal EVs, including early historical studies suggesting their existence in , their putative mechanisms of biogenesis, methods of isolation, and possible roles in the interaction with host cells.

Microbial pathogens generate extracellular vesicles (EVs) for intercellular communication and quorum sensing. Microbial EVs also induce inflammatory pathways within host innate immune cells. We previously demonstrated that EVs secreted by trigger type I interferon signaling in host cells specifically via the cGAS-STING innate immune signaling pathway.

Extracellular vesicles (EVs) are produced by all domains of life. In fungal pathogens, they participate in virulence mechanisms and/or induce protective immunity, depending on the pathogenic species. EVs produced by pathogenic members of the Cryptococcus genus mediate virulence, antifungal resistance, as well as humoral and cell-mediated immunity.

Small molecules are components of fungal extracellular vesicles (EVs), but their biological roles are only superficially known. is a eukaryotic gene that is required for the activity of benzimidazoles against . In this study, during the phenotypic characterization of mutants expected to lack expression, we observed a reduced EV production.

Resistance to fluconazole (FLC), the most widely used antifungal drug, is typically achieved by altering the azole drug target and/or drug efflux pumps. Recent reports have suggested a link between vesicular trafficking and antifungal resistance. Here, we identified novel regulators of extracellular vesicle (EV) biogenesis that impact FLC resistance.
