Bet v 1 is the main cause of type I allergies observed ⚾️ in early spring. Type I, or immunoglobulin E-mediated (IgE-mediated) allergies affect 1 in 5 people in Europe and North America. ⚾️ Commonly observed symptoms are hay fever, dermatitis, asthma and, in severe cases, anaphylactic shock. First contact with these allergens results ⚾️ in sensitisation; subsequent contact produces a cross-linking reaction of IgE on mast cells and concomitant release of histamine. The inevitable ⚾️ symptoms of an allergic reaction ensue. Categorization [ edit ] A nomenclature system has been established for antigens (allergens) that cause IgE-mediated ⚾️ atopic allergies in humans.[2] This nomenclature system is defined by a designation that is composed of the first three letters ⚾️ of the genus; a space; the first letter of the species name; a space and an Arabic number. In the ⚾️ event that two species names have identical designations, they are discriminated from one another by adding one or more letters ⚾️ (as necessary) to each species designation. The allergens in this family include allergens with the following designations: Bet v 1, Dau ⚾️ c 1, and Pru a 1. Other proteins belonging to this family include the major pollen allergens: Structure [ edit ]
