WebWhen two or more high-affinity IgE receptors are brought together by allergen-bound IgE molecules, mediators such as histamine, which are responsible for allergy symptoms, are released. The IgE receptor couples allergen and mast cells to initiate the inflammatory responses that are characteristic of disorders such as hay fever and asthma. WebHigh affinity receptor that binds to the Fc region of immunoglobulins epsilon. Aggregation of FCER1 by multivalent antigens is required for the full mast cell response, including the release of preformed mediators (such as histamine) by degranulation and de novo production of lipid mediators and cytokines.
