| Research Abstract |
Here, we attempted to generate genetically manipulated chickens producing human T -cell epitopes derived from Japanese cedar pollen and anti-allergic cytokine, TGF-ss in order to develop a treatment fro pollen allergy by inducing oral tolerance. The number of sneezing and the allergen-specific IgE level were significantly decreased in allergic mice fed with T-cell epitope-containing egg white. GM chickens harboring TGF-ssgene were generated using oviduct-specific expression system. GM chicken model will extend the usage of therapeutic proteins in eggs, which may serve as edible pharmaceuticals for allergy immunotherapy based on oral tolerance.
