Recombinant vectors can be used to deliver antigens and to stimulate immune responses in humans. Viral vectors possess various intrinsic properties which may lend to advantages and disadvantages for usage for a given therapeutic application [reviewed by Larocca and Schlom] [1]. The safety and flexibility of recombinant viral vectors have lead to their usage in gene therapy, virotherapy, and vac...

BACKGROUND The development of an HIV/AIDS vaccine has proven to be elusive. Because human vaccine trials have not yet demonstrated efficacy, new vaccine strategies are needed for the HIV vaccine pipeline. We have been developing a new HIV vaccine platform using a live enterovirus, coxsackievirus B4 (CVB4) vector. Enteroviruses are ideal candidates for development as a vaccine vector for oral de...

leishmaniasis is a major infectious disease of considerable public health in more than 86 countries around the world. several approaches toward vaccine development against this disease have been taken. glycoprotein (gp63) is conserved among diverse species of leishmania and has induced immunological responses in murine models. therefore, this glycoprotein has been considered as a second generat...

vaccines against the hiv-1 virus offers the best hope for eliminating hiv-associated mortality. recombinant adenovector type 5 (rad5) vaccine is a potential candidate for preventive vaccine strategies. in this study, we evaluated the rad5 prime/protein boost strategy in a murine model. we used rad5 harboring single hiv-1 genes. these genes, including gag (p24) and exon1 of tat, were amplified f...

Both cell mediated and humoral immune responses are required for recovery from Brucella abortus infection. In the development of vaccines capable of providing immunity against brucellosis, L7/L12 50S ribosomal protein has been demonstrated to be one of the protective immunogens of Brucella abortus. The recombinant Brucella abortus L7/L12 ribosomal protein previously produced in the E. coli syst...

introduction: neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in human. pora is a major component of the outer membrane of n. meningitidis and functions as a cationic porin. this study aimed to clone and determine the expression of pora as the first step for producing a proper antigen in a vaccine study against n. meningitidis. methods: an approximately ...

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...

background in spite of dozens of clinical trials to establish effective therapeutic and/or preventive vaccine to resolve hcv infection, no real vaccine has been proved to date. genetic vaccines based on replication-defective adenoviruses have proved to elicit strong and long lasting t-cell responses against a number of viral antigens and are even currently being used for vaccine trials in human...

The development of a new vaccine as a substitute for Bacillus Calmette-Guerin or to improve its efficacy is one of the many World Health Organization goals to control tuberculosis. Mycobacterial vectors have been used successfully in the development of vaccines against tuberculosis. To enhance the potential utility of Mycobacterium smegmatis as a vaccine, it was transformed with a recombinant p...
