Immunization with a chimera consisting of the B subunit of Shiga toxin type 2 and brucella lumazine synthase confers total protection against Shiga toxins in mice.
The striking feature of enterohemorrhagic Escherichia coli (EHEC) infections is the production of Shiga toxins (Stx) implicated in the development of the life-threatening hemolytic uremic syndrome. Despite the magnitude of the social impact of EHEC infections, no licensed vaccine or effective therapy is available for human use. One of the biggest challenges is to develop an effective and safe i...
متن کاملProtection against Shiga toxin-producing Escherichia coli infection by transcutaneous immunization with Shiga toxin subunit B.
Enterohemorrhagic Escherichia coli (EHEC) strains are important human food-borne pathogens. EHEC strains elaborate potent Shiga toxins (Stx1, and/or Stx2) implicated in the development of hemorrhagic colitis (HC) or hemolytic-uremic syndrome (HUS). In this report, we evaluated the immunogenicity and protective efficacy of Stx1 subunit B (StxB1) administered by transcutaneous immunization (TCI)....
متن کاملProduction of Brucella lumazine Synthase Recombinant Protein to Design a Subunit Vaccine against Undulant Fever
Brucella bacterium causes Brucellosis, an infectious disease spreading from animals to human. Brucella lumazine synthase (BLS) is a highly immunogenic protein with adjuvant properties, which has been introduced as an effective protein carrier for vaccine development. This protein also plays a significant role in inducing immune system. This study aimed to clone, express, and purify the BLS gene...
متن کاملNatural killer T (NKT) cells accelerate Shiga toxin type 2 (Stx2) pathology in mice
Shiga toxin-producing Escherichia coli (STEC) is a leading cause of childhood renal disease Hemolytic Uremic Syndrome (HUS). The involvement of renal cytokines and chemokines is suspected to play a critical role in disease progression. In current article, we tested the hypothesis that NKT cells are involved in Stx2-induced pathology in vivo. To address this hypothesis we compared Stx2 toxicity ...
متن کاملMouse model of hemolytic-uremic syndrome caused by endotoxin-free Shiga toxin 2 (Stx2) and protection from lethal outcome by anti-Stx2 antibody.
Hemolytic-uremic syndrome (HUS) results from infection by Shiga toxin (Stx)-producing Escherichia coli and is the most common cause of acute renal failure in children. We have developed a mouse model of HUS by administering endotoxin-free Stx2 in multiple doses over 7 to 8 days. At sacrifice, moribund animals demonstrated signs of HUS: increased blood urea nitrogen and serum creatinine levels, ...
