Introduction: To date, many vaccines have been developed for anthrax but not yet an ideal vaccine. In this study, chimeric protein containing domain 1 lethal factor and domain 4 protective antigens of Bacillus anthracis in copolymer nanocapsules were used to solve the problems caused by existing vaccines and to increase the efficiency of the proposed vaccine. Materials and Methods: In this expe...
Background & Objective: A main contest in chemotherapy is to obtain regulator above the biodistribution of cytotoxic drugs. The utmost promising strategy comprises of drugs coupled with a tumor-targeting bearer that results in wide cytotoxic activity and particular delivery. The B-subunit of Shiga toxin (STxB) is nontoxic and possesses low immunogenicity that exactly binds to t...
we developed an immunogen to stimulate multivalent immunity against hepatitis b surface antigen (hbsag) and hepatitis b core antigens (hbcag). immune responses specific for both hbsag and hbcag play an important role in controlling the infection. hbsag-specific antibodies mediate elimination of virions at an early stage of infection and prevent the spread of virus. the immunogen was constructed...
Background: Cholera disease caused by Vibrio cholerae remains a major cause of morbidity and mortality throughout the world. Various strategies with different proteins as immunogens have been tried for vaccine development, none of which have been sufficiently effective to preclude cholera. Chimeric proteins, with their ability to present multiple antigens at the same time, can play important ro...
background and objectives: hbha and mtb32c have been isolated from culture supernatants of mycobacterium tu- berculosis (m. tuberculosis) and mycobacterium bovis (m. bovis) and their immunogenicity previously studies have been confirmed. in this study, capability of constructed vector containing two mycobacterial immunodaminant antigens (mt- b32c-hbha), in producing new chimeric protein under t...
background: enterotoxigenic escherichia coli (etec) strains are the major causes of diarrheal disease in humans and animals. colonization factors and enterotoxins are the major virulence factors in etec pathogenesis. for the broad-spectrum protection against etec, one could focus on colonization factors and non-toxic heat labile as a vaccine candidate. methods: a fusion protein is composed of a...
Background: Hepatitis C virus (HCV) causes acute and chronic human hepatitis infections. Due to the high genetic diversity and high rates of mutations in the genetic material so far there is no approved vaccine against HCV. Materials and Methods: The aim of this study was to determination B and T cell conserved epitopes of E1 and E2 proteins from HCV and construction of a chimeric pepti...
Background: Neisseria meningitidis, a life-threatening human pathogen with the potential to cause large epidemics, can be isolated from the nasopharynx of 5–15% of adults. The aim of the current study was to evaluate biophysical and biochemical properties and immunological aspects of chimeric acyl-carrier protein-macrophage infectivity potentiator protein-type IV pilus biogenesis protein ...
Background: Enterotoxigenic Escherichia coli (ETEC) strains are the major causes of diarrheal disease in humans and animals. Colonization factors and enterotoxins are the major virulence factors in ETEC pathogenesis. For the broad-spectrum protection against ETEC, one could focus on colonization factors and non-toxic heat labile as a vaccine candidate. Methods: A fusion protein is composed of a...
background and objectives: brucellosis is an important health problem in developing countries and no vaccine is available for the prevention of infection in humans. because of clinically infectious diseases and their economic consequences in human and animals, designing a proper vaccine against brucella is desirable. in this study, we evaluated the immune responses induced by a designed recombi...
