Immunoglobulin E IgE is a type of antibody or immunoglobulin Ig " isotype " that has only been found in mammals. IgE is synthesised by plasma cells. IgE also has an essential role in type I hypersensitivity which manifests in various allergic diseases, such as allergic asthmamost types of sinusitisallergic rhinitisfood allergies, and specific types of chronic urticaria and atopic dermatitis. IgE also plays a pivotal role in responses to allergens, such as: anaphylactic drugs, bee stings, and antigen preparations used in desensitization immunotherapy. Although IgE is typically the least abundant isotype— blood serum IgE levels in a normal "non- atopic " individual are only 0. IgE primes the IgE-mediated allergic response by binding to Fc receptors found on the surface of mast cells and basophils.
