Immunogenicity and protective efficacy of DNA vaccine against visceral leishmaniasis in BALB/c mice
The current study was designed to examine the protective efficacy of DNA vaccines based on gp63 and Hsp70 against murine visceral leishmaniasis. Inbred BALB/c mice were immunized subcutaneously twice at an interval of three weeks with pcDNA3.1(+) encoding T cell epitopes of gp63 and Hsp70 individually and in combination. Animals were challenged intracardially with 10(7) promastigotes of Leishma...
متن کاملStudy of the immunogenicity of outer membrane protein A (ompA) gene from Acinetobacter baumannii as DNA vaccine candidate in vivo
Objective(s): Acinetobacter baumannii is one the most dangerous opportunistic pathogens in hospitalized infections. This bacterium is resistant to 90% of commercial antibiotics. Therefore, developing new strategies to cure A. baumannii-infections is urgent. The DNA vaccines new approach in which the immunogen can be directly expressed inside the target cells through cl...
متن کاملIncreased DNA vaccine delivery and immunogenicity by electroporation in vivo.
DNA vaccines have been demonstrated to be potent in small animals but are less effective in primates. One limiting factor may be inefficient uptake of DNA by cells in situ. In this study, we evaluated whether cellular uptake of DNA was a significant barrier to efficient transfection in vivo and subsequent induction of immune responses. For this purpose, we used the technique of electroporation ...
متن کاملImmunogenicity and Efficacy of Single Antigen Gp63, Polytope and PolytopeHSP70 DNA Vaccines against Visceral Leishmaniasis in Experimental Mouse Model
Polytope approach of genetic immunization is a promising strategy for the prevention of infectious disease as it is capable of generating effective cell mediated immunity by delivering the T cell epitopes assembled in series. Leishmaniasis is a significant world wide health problem for which no vaccine exists. In this study we have compared immunogenicity and efficacy of three types of DNA vacc...
متن کاملIn vivo antigen stability affects DNA vaccine immunogenicity.
The factors that determine the immunogenicity of Ags encoded by viral vaccines or DNA vaccines in vivo are largely unknown. Depending on whether T cell induction occurs via direct presentation of vaccine-encoded epitopes or via one of the different proposed pathways for Ag cross-presentation, the effect of intracellular Ag stability on immunogenicity may possibly vary. However, the influence of...
