Exosomes are membrane-bound structures released by cells into the external environment that carry a significant amount of important cargo, such as proteins, DNA, RNA, and lipids. They play a crucial role in intercellular communication. Parasites have complex life cycles and can release exosomes at different stages. Exosomes released by parasitic pathogens or infected cells contain parasitic nucleic acids, antigenic molecules, virulence factors, drug-resistant proteins, proteases, lipids, etc. These components can regulate host gene expression across species or modulate signaling pathways, thereby dampening or activating host immune responses, causing pathological damage, and participating in disease progression. This review focuses on the means by which parasitic exosomes modulate host immune responses, elaborates on the pathogenic mechanisms of parasites, clarifies the interactions between parasites and hosts, and provides a theoretical basis and research directions for the prevention and treatment of parasitic diseases.
