Rapid DNA vaccination against Burkholderia pseudomallei flagellin by tattoo or intranasal application
Melioidosis is a severe infectious disease with a high mortality that is endemic in South-East Asia and Northern Australia. The causative pathogen, Burkholderia pseudomallei, is listed as potential bioterror weapon due to its high virulence and potential for easy dissemination. Currently, there is no licensed vaccine for prevention of melioidosis. Here, we explore the use of rapid plasmid DNA v...
متن کاملDisabling an integral CTL epitope allows suppression of autoimmune diabetes by intranasal proinsulin peptide.
Insulin is a major target of the autoimmune response associated with destruction of pancreatic beta cells in type 1 diabetes. A peptide that spans the junction of the insulin B chain and the connecting (C) peptide in proinsulin has been reported to stimulate T cells from humans at risk for type 1 diabetes and autoimmune diabetes-prone NOD mice. Here we show that proinsulin B24-C36 peptide binds...
متن کاملPlasmid DNA Vaccine Co-Immunisation Modulates Cellular and Humoral Immune Responses Induced by Intranasal Inoculation in Mice
BACKGROUND An effective HIV vaccine will likely require induction of both mucosal and systemic cellular and humoral immune responses. We investigated whether intramuscular (IM) delivery of electroporated plasmid DNA vaccine and simultaneous protein vaccinations by intranasal (IN) and IM routes could be combined to induce mucosal and systemic cellular and humoral immune responses to a model HIV-...
متن کاملThe modified recombinant proinsulin: a simple and efficient route to produce insulin glargine in E. coli
Background: Recombinant insulin glargine, a long-acting analogue of insulin, is expressed as proinsulin in host cell and after purification and refolding steps cleaved to active insulin by enzymatic digestion using trypsin and carboxypeptidase B. Since the proinsulin's B and C chains have several internal arginine and lysine residues, a number of impurities are generated following treatment wit...
متن کاملInduction of autoimmune diabetes through insulin (but not GAD65) DNA vaccination in nonobese diabetic and in RIP-B7.1 mice.
Insulin has been used to modify T-cell autoimmunity in experimental models of type 1 diabetes. In a large clinical trial, the effect of insulin to prevent type 1 diabetes is currently investigated. We here show that insulin can adversely trigger autoimmune diabetes in two mouse models of type 1 diabetes, using intramuscular DNA vaccination for antigen administration. In female nonobese diabetic...
