Background: Among the enterococci strains, Enterococcus faecalis is considered as one of the important nosocomial pathogens affecting immunocompromised patients. In this study, the immunogenicity of PpiC, GelE, and VS87_01105 proteins against enterococcal infection was investigated in a mice model. Methods: The genes encoding these proteins were cloned into pET21a expression vector, and the rec...
Background: Phosphodiesterase 3A (PDE3A) and phosphodiesterase 3B (PDE3B) play a critical role in the regulation of intracellular level of adenosine 3´,5´-cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3´,5´-cyclic monophosphate (cyclic GMP, cGMP). Subsequently PDE3 inhibitors have shown to relax vascular and inhibit platelet aggregation in cardiovascular disease. Objectives: In th...
pneumococcal autolysins are enzymes involved in cell wall turnover and cellular division physiologically. they have been found to be involved in the pneumococcus pathogenesis. the aim of this study was to identify the autolytic activity of spr1754 as a novel protein of streptococcus pneumoniae . moreover, the binding of the recombinant protein to plasma proteins was also determined. the spr1754...
objective: antigen 85 complex of mycobacterium tuberculosis includes three immunogenic proteins which are important tb vaccine candidates. the use of these protein as a component of subunit vaccines, as a part of dna vaccines or recombinant bcg boosters, enhances their recombinant production. recombinant production of these mycobacterial proteins located in the cell wall somehow differs from th...
Introduction: Hepatitis C virus (HCV) infection is a major public health problem which influences about 170 million people worldwide. Different types of vaccines have been designed using HCV structural proteins to control the viral infection. The core nucleocapsid protein is one of the most conserved proteins and a desirable target for HCV vaccines, especially the protein-based vaccines. In cur...
objective(s): despite treatment with antibiotics and vaccination with bcg, tuberculosis (tb) is still considered as one of the most important public health problems in the world. therefore, designing and producing a more effective vaccine against tb seems urgently. in this study, immunogenicity of a fusion protein which consisting or comprising cfp-10 from mycobacterium tuberculosis and the fc-...
background and objective: use of elastin-like proteins (elps) provides high-performance protein purification without need for chromatography. in line with cost reduction and facilitation of recombinant proteins purification, which represent a high percentage of production costs, in this project, we eliminated the need for proteases in the process of separation of recombinant proteins from elp b...
Background: Pilot and large-scale production of recombinant proteins requires the presence of stable clones capable of producing large quantities of recombinant proteins. Not only the process of selecting stable clones is time consuming, but also the continuous culturing of clones in large-scale production may cause loss of incoming plasmid and recombinant genes. Thus, considering the advanceme...
background: in the recent years, there has been an increasing interest in secretory production of recombinant proteins, due to its various advantages compared with intracellular expression. signal peptides play a critical role in prosperous secretion of recombinant proteins. accordingly, different signal peptides have been assessed for their ability to produce secretory proteins by trial-and-er...
background: shigellosis is a leading cause of diarrhea in many developing countries and although the disease can be controlled and managed with antibiotics, the constant emergence of resistant species requiring ever newer antibacterial drugs make development of an effective vaccine necessary. the bacteria are highly contagious and since immunity to shigella is serotype-specific a multi-serotype...
