Leishmania Extracellular Vesicles as a Preventive Vaccine Platform Against Leishmaniasis

Journal of Extracellular Vesicles, Volume 15, Issue 4, April 2026.
The potential of Leishmania‐derived extracellular vesicles (EVs) as a vaccine platform was investigated, emphasizing an affordable, GMP‐compliant production and purification method. Immunization with EV vaccines, either unadjuvanted or combined with α‐galactosylceramide (αGC), induced robust humoral and cellular immune responses, conferring protection ...
