Equine Summer Eczema

Type I hypersensitivities, or allergies, are mediated by immunoglobulin E (IgE) that causes the release of inflammatory substances from mast cells. In horses, clinical manifestation of allergy often occurs at 4-5 years of age, while sensitization to allergen can precede clinical signs by several years. We have recently shown that immediate skin reactions in horses can be mediated by IgE and also by anti-IgG(T) antibodies. Currently, we investigate whether IgE and IgG(T) both contribute to clinical allergy in the horse.
