Lack gene's immune response induced by cocktail dna vaccine with il-12 gene against cutaneous leishmaniasis in balb/c mice

ABSTRACT

Background: Leishmaniasis is caused by parasitic protozoa of the genus Leishmania which is an obligate intracellular parasite in the infected host. Individuals who have been recovered from clinical leishmaniasis develop strong immunity against reinfection. DNA vaccines are the new type of vaccines that induce expression of protein eukaryotic cells. DNA vaccines can be stimulated by the cellular and humoral immune responses using one or several genes
