WebThe study of autoimmunity mediated by immunoglobulin E (IgE) autoantibodies, which may be termed autoallergy, is in its infancy. It is now recognized that systemic lupus erythematosus, bullous pemphigoid (BP), and chronic urticaria, both spontaneous and inducible, are most likely to be mediated, at least in part, by IgE autoantibodies. The … WebAug 10, 2024 · Immunoglobulin E (IgE) is defined by the presence of the epsilon heavy chain in the structure. IgE exists as a monomer and is the least abundant antibody isotype in plasma, present at levels (about 100 ng/mL), approximately 300-fold lower than that of IgG in a circulation and accounts for 0.002% of total immunoglobulin.
