Objective(s): Tuberculosis (TB) has still remained a global health issue. One third of the world's population is infected with tuberculosis and the current BCG vaccine has low efficiency; hence, it is necessary to develop a new vaccine against TB. The aim of the current study was to evaluate the efficiency of a novel DNA vaccine encoding Mtb32C-HBHA antigen in inducing specific immune responses...
Objective(s): Infection with tuberculosis (TB) is regarded as a major health issue. Due to the emergence of antibiotic resistance during TB treatment, prevention via vaccination is one of the most effective ways of controlling the infection. DNA vaccines are developed at a greater pace due to their ability in generating a long-lasting immune response, higher safety com...
background: improving vaccine potency in the induction of a strong cell-mediated cytotoxicity can enhance the efficacy of vaccines. necrotic cells and the supernatant of necrotic tumor cells are attractive adjuvants, on account of their ability to recruit antigen-presenting cells to the site of antigen synthesis as well as its ability to stimulate the maturation of dendritic cells. objective: t...
Objective(s): Mycobacterium tuberculosis (M. tuberculosis), an intracellular pathogen, causes 1.5 million deaths globally. Bacilli Calmette-Guérin (BCG) is commonly administered to protect people against M. tuberculosis infection; however, there are some obstacles with this first-generation vaccine. DNA vaccines, the third generation vaccines, can induce cellular immun...
Bovine herpesvirus 1 (BoHV-1) has frequently been used as a model for testing parameters affecting DNA immunisation in large animals like cattle. However, the selection of target antigens has been poorly studied, and most of the experiments have been conducted in mice. In the present study, we demonstrated in cattle that a DNA vaccine encoding BoHV-1 glycoprotein gD induces higher neutralising ...
conclusions these results exhibited the immuno potentiator effects of mip-3beta plasmid when coadministrated with the hcv core dna vaccine. complimentary studies integrating mip-3beta as a genetic adjuvant in hcv-core-dna vaccination models are warranted. results mice covaccinated with mip-3beta elicited an enhanced th1 biased systemic immune response as evidenced by higher ifn-γ/il-4 and anti-...
Bordetella avium is the causative agent of bordetellosis, which remains to be the cause of severe losses in the turkey industry. Given the lack of vaccines that can provide good protection, developing a novel vaccine against B. avium infection is crucial. In this study, we constructed a eukaryotic expression plasmid, which expressed the outer membrane protein A (ompA) of B. avium, to prepare a ...
the prevalence of hepatitis c virus (hcv) is approximately 3% around the world. this virus causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. the effectiveness of interferon-α and ribavirin therapy is about 50% and is associated with significant toxicity and cost. hence, generating new vaccines or drugs is an obligation. however, there is no vaccine available for clinical u...
BACKGROUND Hypervariability of HCV proteins is an important obstacle to design an efficient vaccine for HCV infection. Multi-epitope vaccines containing conserved epitopes of the virus could be a promising approach for protection against HCV. OBJECTIVES Cellular and humoral immune responses against multi-epitope DNA and peptide vaccines were evaluated in BALB/c mice. MATERIALS AND METHODS I...
BACKGROUND We conducted a double-blind, randomized, placebo-controlled Phase I study of a recombinant replication-defective adenovirus type 5 (rAd5) vector expressing HIV-1 Gag and Pol from subtype B and Env from subtypes A, B and C, given alone or as boost following a DNA plasmid vaccine expressing the same HIV-1 proteins plus Nef, in 114 healthy HIV-uninfected African adults. METHODOLOGY/PR...
