[ immunoglobulin E, IgE]
Immunoglobulin E (IgE) is an antibody in mammals, functionally a part of the adaptive immune system to fight off parasites such as flukes and worms. It is produced by plasma cells and only represents o.o5% of the total immunoglobulins.
IgE is responsible for type I hypersensitivity to allergens and, despite it’s low concentration, is capable of triggering a strong inflammatory reaction.
