background: cryptosporidium parvum is a parasitic protozoan that functions as important causa­tive agent of diarrhea in human and animals. the host's immune response to surface anti­gens of c. parvum has been previously demonstrated. in this respect, the role of humoral immu­nity in the development of host protective immunity against this protozoon has been well demon­strated. methods: the effe...

objective(s): production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. the goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. materials and methods: multiple amino acid sequences of different i...

molecular farming has been considered as a secure and economical approach for production of biopharmaceuticals. human tnf related apoptosis inducing ligand (trail) as a promising biopharmaceutical candidate has been produced in different expression hosts. however, little attention has been paid to molecular farming of the trail in spite of numerous advantages of plant expression systems. theref...

background brucellosis is an important cosmopolitan infection disease caused by organisms belonging to the genus brucella. the cgt gene (cyclic β-1, 2 glucan transporter gene) is a virulent factor in brucella genus. the present study was conducted with the aim of cloning and expression of brucella cgt gene. materials and methods brucella melitensis cgt gene was amplified from extracted chromoso...

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...

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...
