Immunologic Evaluation of DNA Vaccine Encoding Influenza Virus M2 Gene in Type A- Influenza Mice Model
Abstract Background and Objective: The M2 gene expressing the conserved protein in influenza virus can be used to make a single-dose vaccine with permanent immunity. Material and Methods: The mice were allocated to one case group immunized with pcDNA3-M2 and two control groups with pcDNA and PBS, in three dozes with interval of two weeks. Two weeks after the last injection, Cellular imm...
متن کاملEffect of LIGHT Adjuvant on Kinetics of T-Cell Responses Induced by HSV-1 DNA Immunization
Background: Studies on efficacy of various vaccines that prevent or reduce the primary and recurrent HSV-1 infection have demonstrated the importance of cellular immunity for protection against the infection. We previously used DNA vaccination to induce cellular immunity against HSV-1 infection in mice. Objective: The aim of our study was to evaluate the effect of LIGHT, a member of TNF super f...
متن کاملProtective Immunity in Mice Following Immunization with the Cochleate-Based Subunit Influenza Vaccines
High morbidity and mortality of influenza virus infection makes it an important disease world-wide. Mouse is a very well-studied animal model for this disease with similar manifestation to human disease. It would be desirable to induce mucosal as well as circulating immune responses to obtain protection from infection and to decrease the spread of the virus. Cell mediated immunity (proliferativ...
متن کاملThe Effect of Glycoprotein B DNA Immuniation on HSV-l Lethal Infection of BALB/c Mice
Background and Aims: Glycoprotein B (gB) is among the most important immunogenic proteins of HSV-1 that is now being used as recombinant vaccine to induce protectively against the virus. It is believed that gB is responsible for induction of neutralizing antibody and up to 90% of CTL (Cytotoxic T Cell) activity against HSV-1 in some haplotypes. Methods: In the present study the antibody titer ...
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...
