Abstract
Allergen-specific IgG responses were measured by ELISA in sera from twelve horses not exposed to Culicoides, before and after vaccination with E. coli-rCul n 3 and 4. Before vaccination no IgG binding to the barley and insect cell produced proteins was detected and a similar increase in specific IgG was observed after vaccination. While IgG levels to the E.coli expressed proteins were higher in the post-vaccination sera, some background binding was observed pre-vaccination. In vitro re-stimulation of PBMC was performed for measurements of cytokines. E. coli expressed proteins resulted in high background in PBMC from non-vaccinated controls. The barley and insect cell expressed proteins induced similar amount of IFN-γ and IL-4 in PBMC from vaccinated horses. Barley produced allergens are promising tools for use in immunoassays.
