Comparative analysis using a mouse model of the immunogenicity of artificial VLP and attenuated Salmonella strain carrying a DNA-vaccine encoding HIV-1 polyepitope CTL-immunogen.

چکیده
Two systems have been examined for delivery of DNA-vaccine encoding a HIV-1 polyepitope CTL-immunogen (TCI). One is intended for i.m. injection and is in the form of an artificial virus like particle containing eukaryotic expression plasmid pcDNA-TCI encapsulated within a spermidine-polyglucin conjugate. The other is intended for mucosal immunization and is based on attenuated Salmonella typhimurium strain 7207, which can deliver pcDNA-TCI directly into professional antigen-presenting cells (APC). After immunization, the artificial VLP and recombinant Salmonella induced an enhanced HIV specific serum antibody, proliferative and CTL responses compared to those induced by naked pcDNA-TCI. The most significant responses were produced when pcDNA-TCI was delivered by Salmonella.

This study is focusing on elucidation of the capacity of attenuated Salmonella enteritidis E23 (cya, crp) to serve as a vehicle for the rectal delivery of the DNA vaccine. Earlier for creation HIV-1 candidate DNA vaccine we have designed the polyepitope protein TCI (T-cell immunogen), which comprises over 80 CTL epitopes from subtype A, B and C HIV-1 proteins. The gene coding for TCI protein wa...
متن کاملImmunogenicity of a New HIV-1 DNA Construct in a BALB/c Mouse Model
Background: Cell mediated immunity, especially cytotoxic T cell responses against HIV-1 infection, plays a critical role in controlling viral replication and disease progres-sion. DNA vaccine is a novel technology which is known to stimulate strong cellular immune responses. Many DNA vaccines have been tested for HIV infection but there is still no effective vaccine against this infection. Cons...

Objective(s): Vaccination is one of the most effective means to protect humans and animals against brucellosis. Live attenuated Brucella vaccines are considered effective in animals but they may be potentially infectious to humans, so it is vital to improve the immunoprotective effects and safety of vaccines against Brucella. This study was designed to evaluate the immunogenicity of DNA vaccine...
متن کاملImmunogenicity Evaluation of a DNA Vaccine Expressing the Hepatitis C Virus Non-Structural Protein 2 Gene in C57BL/6 Mice
Backgrounds: Most of the hepatitis C virus (HCV) infections elicit poor immune responses and 75% to 85% of cases become chronic therefore, the development of an effective vaccine against HCV is of paramount importance. In this study, we aimed to evaluate co-administration of HCV non-Structural Protein 2 and IL-12 DNA vaccines in C57BL/6 mice. Methods: A plasmid encoding full-length HCV NS2 prot...

Haemorrhagic septicaemia (HS) is a fatal systemic disease of cattle and buffaloes. Some control isachieved with administration of alum-precipitated or oil-adjuvanted killed whole-cell vaccines injectedsubcutaneously. These vaccines, however, provide only short-term immunity and for effective use, theyshould be administered annually. We constructed an aroA attenuated derivative of a Pasteurella ...
