Excreted-secreted Ags (ESA) of Toxoplasma gondii (Tg) play an important role in the stimulation of the host immune system in both acute and chronic infections. To identify the parasite Ag(s) involved in the maintenance of T cell-mediated long term immunity, 40 ESA-specific T cell clones were derived from three chronically infected healthy subjects. All the clones were CD4+ and recognized both E...
Background: Recently, botulinum neurotoxin (BoNT)-derived recombinant proteins have been suggested as potential botulism vaccines. Here, with concentrating on BoNT type E (BoNT/E), we studied two of these binding domain-based recombinant proteins: a multivalent chimer protein, which is composed of BoNT serotypes A, B and E binding subdomains, and a monovalent recombinant protein, which contains...
Background: Recombinant vaccine technology is one of the most developed means in controlling infectious diseases. However, an effective vaccine against Shigella is still missing. Objective: To evaluate recombinant IpaC protein of Shigella as a vaccine candidate. Methods: In this study we cloned IpaC gene into an expression vector in prokaryotic system. The protein expression was evaluated by SD...
Abstract: Background: Streptokinase has been widely prescribed as a fibrinolytic agent for myocardial infarction. Simple structural characteristics of this protein have provided techniques for production of different recombinant types of this protein. The present study was designed to prepare equisimilisH46A subtype of streptokinase in our country. Materials and methods: Having extracted the...
the influenza a virus is of global concern for the poultry industry, especially the h5 subtype as it has the potential to become highly pathogenic for poultry and mankind. recently, plant expression systems have gained interest as an alternative for the production of vaccine antigens. the goal of the present study was to investigate the possibility of expressing the ha1 protein in nicotiana tab...
background: the advent of recombinant dna technology has facilitated heterologous expression of proteins from various sources in different host systems including escherichia coli. if a plant virus coat protein is expressed in the bacterium it can be used as the antigen for antibody preparation. such a recombinant antigen preparation can be particularly useful where equipment such as ultracentri...
Objective(s): Vascular endothelial growth factor (VEGF) is one of the most effective proteins in angiogenesis, mesenchymal stem cells (MSCs) differentiation and wound healing. These abilities are therapeutic potential of VEGF in diabetic retinopathy, nephropathy and other tissue damage circumstances. In this study, recombinant VEGF was produced in Escherichia coli (E. coli) system and then biol...
Background and purpose: The most common cause of diarrhea is Shigella and no vaccine has been found so far. IpaD and STxB proteins (B subunit of Shiga toxin) play an important role in invasion, infection and pathogenesis caused by Shigella. To evaluate the immunogenicity of each of the proteins IpaD and STxB can using of two animal models mice and guinea pigs and could be determined role of eac...
Objective(s): Enterotoxigenic Escherichia coli (ETEC) strains are one of the primary causes of diarrhea in newborn calves and in humans, pigs, and sheep. IgY technology has been identified as a promising alternative to generating a mass amount of specific antibody for use in immunotherapy and immunodiagnostics. The purpose of this study was to produce specific antibody by egg yolk antibody (IgY...
