AIM To assess the efficacy and safety of in vivo electroporation (EP)-mediated dual-plasmid hepatitis B virus (HBV) DNA vaccine vs placebo for sequential combination therapy with lamivudine (LAM) in patients with chronic hepatitis B. METHODS Two hundred and twenty-five patients were randomized to receive either LAM + vaccine (vaccine group, n = 109) or LAM + placebo (control group, n = 116). ...
Objectives 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 ag...
Background: Human colorectal cancer cells overexpress carcinoembryonic antigen (CEA). CEA is a glycoprotein which has shown to be a promising vaccine target for immunotherapy against colorectal cancer. Objective: To design a DNA vaccine harboring CEA antigen and evaluate its effect on inducing immunity against colorectal cancer cells in tumor bearing mice. <str...
Background: Cervical cancer is the most prevalent tumor in developing countries and the second most frequent cancer among female population worldwide. Specific human papillomaviruses and, most notably, HPV types 16 and 18 are recognized as being caus-ally associated with cervical carcinomas. The early HPV type 16 genes, E6 and E7, di-rectly participate in the in vitro transformation of primary ...
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...
DNA vaccine may be a promising tool for controlling tuberculosis development. However, vaccines encoding single antigens of mycobacterium did not produce protective effect as BCG did. In the present study, we evaluated the immunogenicity and protective efficacy of a divalent DNA vaccine encoding two immunodominant antigens Ag85B and MPT64 of Mycobacterium tuberculosis. We found that both humora...
Background: Tuberculosis (TB) remains as a major cause of death around the world. Construction of a new vaccine against tuberculosis is an effective way to control it. Several vaccines against this disease have been developed. The aim of the present study was to cloning of tb10.4 gene in pcDNA3.1+ plasmid and evaluation of its expression in eukaryotic cells. ...
Inefficient DNA delivery methods and low expression of plasmid DNA have been major obstacles for the use of plasmid DNA as vaccine for HIV/AIDS. This review describes successful efforts to improve DNA vaccine methodology over the past ~30 years. DNA vaccination, either alone or in combination with other methods, has the potential to be a rapid, safe, and effective vaccine platform against AIDS....
Virus-specific CD4(+) T cell responses have been shown to play a critical role in controlling HIV-1 replication. Candidate HIV-1 vaccines should therefore elicit potent CD4(+) as well as CD8(+) T cell responses. In this report we investigate the ability of plasmid GM-CSF to augment CD4(+) T cell responses elicited by an HIV-1 gp120 DNA vaccine in mice. Coadministration of a plasmid expressing G...
