DNA vaccination with a plasmid encoding LACK-TSA fusion against Leishmania major infection in BALB/c mice.
Vaccination would be the most important strategy for the prevention and elimination of leishmaniasis. The aim of the present study was to compare the immune responses induced following DNA vaccination with LACK (Leishmania analogue of the receptor kinase C), TSA (Thiol-specific-antioxidant) genes alone or LACK-TSA fusion against cutaneous leishmaniasis (CL). Cellular and humoral immune response...
متن کاملDNA immunization with the gene encoding P4 nuclease of Leishmania amazonensis protects mice against cutaneous Leishmaniasis.
Infection with the protozoan parasite Leishmania amazonensis can cause diverse clinical forms of leishmaniasis. Immunization with purified P4 nuclease protein has been shown to elicit a protective response in mice challenged with L. amazonensis and L. pifanoi. To explore the potential of a DNA-based vaccine, we tested the L. amazonensis gene encoding P4 nuclease as well as adjuvant constructs e...
متن کاملProtective vaccination against experimental canine visceral leishmaniasis using a combination of DNA and protein immunization with cysteine proteinases type I and II of L. infantum.
Leishmania infantum is known to be associated with visceral leishmaniasis in Iran and canids are natural reservoirs. Control of disease in dogs appears to be one of the most effective approaches for interrupting the domestic cycle of the disease. In search for successful vaccine strategies, we evaluated the cysteine proteinases (CPs) type I and II using a heterologous prime-boost regime for vac...
متن کاملImmunization with Leishmania major exogenous antigens protects susceptible BALB/c mice against challenge infection with L. major.
The potential of Leishmania major culture-derived soluble exogenous antigens (SEAgs) to induce a protective response in susceptible BALB/c mice challenged with L. major promastigotes was investigated. Groups of BALB/c mice were immunized with L. major SEAgs alone, L. major SEAgs coadministered with either alum (aluminum hydroxide gel) or recombinant murine interleukin-12 (rmIL-12), L. major SEA...
متن کاملimmunological responses of naturally infected dogs to type i and ii recombinant cysteine proteinases of leishmania infantum
purpose: evaluation of humoral and cellular immune responses of naturally infected dogs against type i (rcpb) (recombinant cycsteine proteinase b), and ii (rcpa) (recombinant cycsteine proteinase a) recombinant cysteine proteinases and c-terminal extension (cte) of leishmania infantum (l. infantum). materials and methods: in this study, fourteen infected dogs (7 with symptoms, 7 asymptomatics)...
متن کاملDNA vaccination protects mice against challenge with Listeria monocytogenes expressing the hepatitis C virus NS3 protein.
The goal of this study was to develop a new surrogate challenge model for use in evaluating protective cell-mediated immune responses against hepatitis C virus (HCV) antigens. The use of recombinant Listeria monocytogenes organisms which express HCV antigens provides novel tools with which to assay such in vivo protection, as expression of immunity against this hepatotropic bacterial pathogen i...
