Extracellular vesicles release from protozoa parasite and animal model

Diseases caused by protozoan parasites, such as leishmaniasis, trypanosomiasis, and malaria, are highly complex and together continue to cause high annual morbidity and mortality. The search for new compounds in environmental biodiversity, repositioning known drugs, and developing vaccines using old and innovative technologies have been employed to discover vaccines and new and alternative treatments. Extracellular vesicles (EVs) can carry parasite antigens, creating a new possibility to develop an effective and affordable platform for treatment, vaccines, and drug delivery. Thus, the evaluation of EVs in animal models can and should be explored among the countless biomedical applications. Herein, we will address the concept of EVs, their acquisition and characterization in protozoan parasite models, and the primary studies using these vesicles in therapeutic applications.
