This paper reports a versatile egfp-tagged pFL61based expression vector system which allows the production on yeast of homoand heterologous proteins fused with the Enhanced Green Fluorescent Protein (EGFP) at the C-terminus. This expression system, which involves a fluorescent protein, readily allows both to verify the expression and to localize the protein in the yeast cell. The vector carries...

BACKGROUND Yeast is recognized as a generally safe microorganism and is utilized for the production of pharmaceutical products, including vaccines. We previously showed that expression of human immunodeficiency virus type 1 (HIV-1) Gag protein in Saccharomyces cerevisiae spheroplasts released Gag virus-like particles (VLPs) extracellularly, suggesting that the production system could be used in...

objective(s):human cytomegalovirus (hcmv) remains a major morbidity and mortality cause in immuno suppressed patients. therefore, significant effort has been made towards the development of a vaccine. in this study, the expression of the pp65 and gb fusion peptides and fc domain of mouse igg2a as a novel delivery system for selective uptake of antigens by antigen-presenting cells (apcs) in pich...

VopE, a mitochondrial targeting T3SS effector protein of Vibrio cholerae, perturbs innate immunity by modulating mitochondrial dynamics. In the current study, ectopic expression of VopE was found to be toxic in a yeast model system and toxicity was further aggravated in the presence of various stressors. Interestingly, a VopE variant lacking predicted mitochondrial targeting sequence (MTS) also...

Objective(s):Human Cytomegalovirus (HCMV) remains a major morbidity and mortality cause in immuno suppressed patients. Therefore, significant effort has been made towards the development of a vaccine. In this study, the expression of the pp65 and gB fusion peptides and Fc domain of mouse IgG2a as a novel delivery system for selective uptake of antigens by antigen-presenting cells (APCs) in Pich...

hepatitis c virus (hcv) is an important agent causing chronic liver infection, which often leads to liver cirrhosis and lethal hepatocellular carcinoma (hcc). at present, there is no effective hcv vaccine for prevention of hepatic disease and the standard treatment is neither economical nor fully effective in all the patients. however, vaccination based on structural and nonstructural proteins ...

Background: Little knowledge of synonymous codon usage pattern of pseudorabies virus (PRV) genome, especially the UL31 gene in the process for its evolution is available. Objectives: In the present study, the codon usage bias between PRV UL31 sequence and the UL31-like sequences was identified. Materials and Methods: We used a comprehensive analysi...

the genome of hb v virus of serotype ayw cloned in pbr322 and expression shuttle vector p yes2 were used for construction of the hbsag chimeric genes and their expression in saccharomyces cerevisiae. two recombinant plasmids were constructed. one of them contained the coding sequences for the major polypeptide of surface antigen. another construct carried the major polypeptide with the pre-s2 a...
