ABSTRACT
Different works of DNA based vaccination against leishmaniasis highlight the complexity of the induced immune responses to fight against the disease. In this work, we exploited the capacity of IL-12 and GMC-SF to activate immune cell mediators and effectors to induce a Th1 response, more capable of clearing the parasite. To generate these immunomodulating activities, we associated eukaryotic expressing vectors of murine IL-12 and GMC-SF to several DNA based vaccine candidates encoding to several L. (L.) major antigens, in the BALB/c mouse. When mice were challenged with a high parasitic load in the hind footpad, no additional protective effect could be generated. However, when the challenge was carried out in the inner face of the ear with a small parasitic load, the association of plasmids encoding to IL-12 and GMC-SF to DNA based vaccination, the protective effects were increased.
