Extracellular Vesicles of Giardia duodenalis: Unravelling Their Virulence Factors and Potential to Induce Protection Against Experimental Giardiasis

open access: yesJournal of Extracellular Biology, Volume 5, Issue 6, June 2026.
ABSTRACT Extracellular vesicles (EVs) are key mediators of intercellular communication, enabling trans‐kingdom exchange of proteins, nucleic acids, lipids, and metabolites. In Giardia duodenalis, EVs contribute to parasite survival, host–pathogen interactions, and immune modulation.
