Immunoglobulin E-mediated hypersensitivity
Term · Chemistry · MLC-T-CHM-005678
An allergic reaction, also known as a type I hypersensitivity reaction, that is triggered by the binding of an allergen to immunoglobulin E (IgE) antibodies. Upon initial exposure to an allergen, susceptible individuals produce specific IgE antibodies that bind to the surface of mast cells and basophils. Subsequent exposure to the same allergen causes cross-linking of these bound IgE molecules, leading to rapid degranulation of the cells and the release of inflammatory mediators like histamine, which produce the symptoms of an allergic reaction.
