Abstract
Immunoglobulin (Ig) E is a mediator of food allergic reaction; however, the mechanisms of its production in response to an ingested antigen are not fully understood. For analysis of IgE production, here we propose an IgE response mouse model created by injection of a Th2 cell culture and feeding of an egg white diet. According to this manipulation, total and ovalbumin specific IgE production were elevated in this model. We think our model enables us to analyze IgE induction by Th2 cells in food allergy and can contribute to the development of a treatment for food allergy.
