    Production of Escherichia coli heat labile toxin (LT) B subunit in soybean seed and analysis of its immunogenicity as an oral vaccine

  • Original language description

    The B subunit of the heat labile toxin of enterotoxigenic Escherichia coli (LTB) was used as a model immunogen for production in soybean seed. LTB expression was directed to the endoplasmic reticulum (ER) of seed storage parenchyma cells for sequestration in de novo synthesized inert protein accretions derived from the ER. Pentameric LTB accumulated to 2.4% of the total seed protein at maturity and was stable in desiccated seed. LTB-soybean extracts administered orally to mice induced both systemic IgGand IgA, and mucosal IgA antibody responses, and was particularly efficacious when used in a parenteral prime-oral gavage boost immunization strategy. Sera from immunized mice blocked ligand binding in vitro and immunized mice exhibited partial protection against LT challenge. Moreover, soybean-expressed LTB stimulated the antibody response against a co-administered antigen by 500-fold. These results demonstrate the utility of soybean as an efficient production platform for vaccines that

    Exprese B-podjednotky tepelně-labilního toxinu Escherichia coli v sojových bobech a analýza její imunogenicity při orálním podání

  • Czech description

    Jako modelový antigen pro expresi v sojových bobech jsme vybrali B-podjednotku enterotoxinu E. coli (LTB). Expresi transgenu jsme směrovali do nového buněčného kompartmentu ? proteinových tělísek odvozených od ER. V analyzované linii se funkční pentamerický antigen akumuloval do přibližně 2,5% celkového proteinu. Po orální imunizaci myší sojovým extraktem se podařilo prokázat částečnou ochranu před otravou LT toxinem. Navíc byla pozorována výrazná adjuvantní aktivita- sojový LTB zesílil imunitní odpověďproti současně podanému dalšímu antigenu zhruba 500-krát.
