Human IgE Lambda Protein
IgE is the least abundant immunoglobulin (Ig) but it has a central role in allergic diseases. Blood serum IgE levels in a normal ("non-atopic") individual are ~150 ng/ml, compared to 10 mg/ml for the Igs. IgE binds to various immune cells, and upon allergic recognition, it can trigger an inflammatory response from those cells. Most IgE research has been centered around the mechanism of a form of allergy known as type 1 hypersensitivity. Additionally, IgE may be an important target in treatments for allergy and asthma. Some recent investigations have led to suggestions that IgE is involved in recognition of cancer.
