Abstract Activation of innate immunity using adjuvants that activate Toll-like receptor 4 pathways have great potential for improving the protection induced by parasite vaccines. We investigated protective and therapeutic effects of a vaccine against leishmaniasis containing a combination of an adjuvant synthetic lipid A-analogue, ONO-4007 and Leishmania amazonensis antigens. ONO-4007 was co-injected with soluble and membrane-enriched L. amazonensis-amastigote antigens into BALB/c mice that had either already been infected with 1 x 10(6) L. amazonensis promastigotes (immunotherapy study) or before challenge with the same infectious dose (immunoprophylaxis study). Sixty percent of mice vaccinated before infectious challenge controlled their Leishmania infections - defined by the absence of footpad-swelling and negative Leishmania cultures - compared to 0% of controls, and 40% of mice vaccinated after infection resolved their infections compared to 0% of controls. Protective immunity in both immunoprophylaxis and immunotherapy models was associated with increased protein production of IL-12 and IFN-gamma. These data suggest that vaccination with a combination of ONO-4007 and amastigote antigens of L. amazonensis may be useful for the prevention and treatment of leishmaniasis, and that the protective immunity induced is associated with the production of type-1 cytokines.
