IgEabhängigen

IgEabhängigen refers to a process or reaction that is dependent on Immunoglobulin E (IgE). IgE is a class of antibodies that plays a crucial role in the immune system, particularly in allergic reactions. When the body is exposed to a foreign substance, such as pollen, dust mites, or certain foods, that it perceives as harmful, it can produce IgE antibodies. These IgE antibodies then bind to mast cells and basophils, two types of white blood cells. Upon subsequent exposure to the same allergen, the allergen binds to the IgE antibodies already attached to the mast cells and basophils. This binding triggers the release of potent inflammatory mediators, such as histamine, from these cells. These mediators cause the characteristic symptoms of allergic reactions, including itching, swelling, redness, and in severe cases, anaphylaxis. Therefore, any process described as IgEabhängigen signifies that IgE antibodies are the primary mediators initiating or driving that particular immune response. This mechanism is central to understanding conditions like asthma, hay fever, and food allergies.
