Parenteral adjuvant potential of recombinant B subunit of Escherichia coli heat-labile enterotoxin
BACKGROUND The B subunit of Escherichia coli heat-labile enterotoxin (LTB) is a potent mucosal immune adjuvant. However, there is little information about LTB's potential as a parenteral adjuvant. OBJECTIVES We aimed at evaluating and better understanding rLTB's potential as a parenteral adjuvant using the fused R1 repeat of Mycoplasma hyopneumoniae P97 adhesin as an antigen to characterise t...
متن کاملPreparation of biocompatible heat-labile enterotoxin subunit B-bovine serum albumin nanoparticles for improving tumor-targeted drug delivery via heat-labile enterotoxin subunit B mediation
Heat-labile enterotoxin subunit B (LTB) is a non-catalytic protein from a pentameric subunit of Escherichia coli. Based on its function of binding specifically to ganglioside GM1 on the surface of cells, a novel nanoparticle (NP) composed of a mixture of bovine serum albumin (BSA) and LTB was designed for targeted delivery of 5-fluorouracil to tumor cells. BSA-LTB NPs were characterized by dete...
متن کاملModulation of B lymphocyte signalling by the B subunit of Escherichia coli heat-labile enterotoxin.
The non-toxic B subunit of Escherichia coli heat-labile enterotoxin (EtxB) is a potent mucosal adjuvant and immunomodulator capable of blocking autoimmune disease. These effects are linked with its ability to modulate lymphocyte populations--a feature that is dependent on binding to ubiquitously expressed cell surface receptors. Here, we demonstrate that EtxB can trigger up-regulated expression...
متن کاملGlycosphingolipids as novel targets for T-cell suppression by the B subunit of recombinant heat-labile enterotoxin.
Heat-labile enterotoxin subunit B (LTB) is a noncatalytic protein derived from Escherichia coli that binds to ganglioside GM1, a glycosphingolipid on the surface of mammalian cells. In this study, the effects of recombinant LTB (rLTB) on murine lymphocytes were examined in vitro. T and B cells readily bound fluorescein isothiocyanate-labeled rLTB. CD8+ T cells bound twice as much as CD4+ T cell...
متن کاملantibody against recombinant heat labile enterotoxin b subunit (rltb) could block lt binding to ganglioside m1 receptor
objectives: enterotoxigenic escherichia coli (etec) is one of the most common agents of diarrhea among other bacterial agents. designing and producing vaccine against these bacteria is one of the major purposes of world health organization (who). due to presence of diverse clones of etec strains in the world, the use of global vaccines for etec infection is controversial. b subunit of heat labi...
