BACKGROUND Evidence that simian virus 40 (SV40) is associated with human mesotheliomas, osteosarcomas, and brain tumors suggests that a recombinant vaccine directed against lethal cancers expressing SV40 T antigen (Tag) could have clinical utility. To address this potential need, we designed a novel vaccinia virus construct that encodes an SV40 Tag in which oncogenic domains were excluded and i...

BACKGROUND Severe and fatal complications of toxoplasmosis urge development of effective vaccines against the disease. The current study was performed to evaluate cocktail DNA vaccine containing plasmids encoding GRA5, SAG1, and ROP2 genes of Toxoplasma gondii in BALB/c mice in Tarbiat Modares University in 2012.

Gas vesicle (Vac) synthesis in Halobacterium salinarium PHH1 involves the expression of the plasmid pHH1-encoded vac (p-vac) region consisting of 14 different gvp genes that are arranged in two clusters, p-gvpACNO and, oriented in the direction opposite to that of gvpA, p-gvpDEFGHIJKLM. The p-gvpACNO region was analyzed at the transcriptional and functional levels in H. salinarium and in Halofe...

Enterohaemorrhagic Escherichia coli (EHEC) cause haemolytic uraemic syndrome (HUS), a thrombotic microangiopathy resulting from endothelial injury in the renal glomeruli and other organs. EHEC virulence factors that damage the microvascular endothelium play therefore major roles in the pathogenesis of HUS. We identified an EHEC strain that vacuolates and kills primary human glomerular microvasc...

Development of potent new anti-Shigella agents for rapid and specific detection and treatment is of great importance. Aptamers, nucleic acid oligomers capable of specific binding to a wide range of non-nucleic acid targets, may be of value for this purpose. In the present study, we used a Systematic Evolution of Ligands by Exponential enrichment (SELEX) process to select DNA aptamers that b...

D-galactose induces pancreatic disorder along with aging mouse model. Vitex agnus-castus (VAC) has potential pancreatic protective effect. Hence, this study was designed to evaluate the hypoglycemic and pancreas protective effects of VAC hydroalcoholic extract in D-galactose-induced aging female mice. In the present experimental study, 72 adult female Naval Medical Research Institute (NMRI) mic...

Background The severe damages of toxoplasmosis clearly indicate the need for the development of a more effective vaccine. Immunization with plasmid DNA is a promising vaccination technique. Therefore, GRA7 plasmid was prepared to be used as a vaccine. The purpose of this study was evaluation of immunization with cocktail DNA vaccine including plasmids encoding Toxoplasma gondii ROP2 and GRA7 in...
