IGE RECEPTORS Meaning and
Definition
-
IgE receptors, also known as immunoglobulin E receptors, refer to specific proteins found on the surface of certain immune cells, such as mast cells and basophils, which play a pivotal role in triggering allergic responses in the human body. These receptors are crucial for the recognition and binding of immunoglobulin E (IgE) antibodies, which are a type of antibody involved in allergic reactions.
When an individual with allergies encounters an allergen, it stimulates the production of IgE antibodies by B cells in the immune system. These IgE antibodies then bind to the IgE receptors on mast cells and basophils, sensitizing these cells to the specific allergen.
The binding of allergen-specific IgE to the IgE receptors primes the immune cells for subsequent encounters with the allergen. Upon re-exposure to the allergen, it binds to the IgE antibodies already attached to the IgE receptors, causing cross-linking of the receptors, which triggers the release of various chemical mediators, such as histamine and leukotrienes. These mediators cause the characteristic symptoms of allergic reactions, such as itching, inflammation, sneezing, and nasal congestion.
Understanding IgE receptors has played a crucial role in the development of allergy treatments, including antihistamines, corticosteroids, and immunotherapy. By targeting these receptors, researchers and clinicians aim to prevent the activation of allergic responses, alleviate symptoms, and ultimately provide relief to individuals suffering from allergies.

Etymology of IGE RECEPTORS
The term "IgE receptors" is derived from two main components: "IgE" and "receptors".
"IgE" is short for immunoglobulin E, which is a type of antibody involved in allergic reactions and defense against parasitic infections. The "Ig" part of the term indicates that it belongs to the immunoglobulin family, which are proteins produced by the immune system to bind to specific targets (antigens).
"Receptors" refer to proteins on the surface of cells that bind to specific molecules, such as antibodies, hormones, or neurotransmitters. Receptors play a crucial role in cellular signaling pathways, allowing cells to receive signals from the external environment and initiate appropriate responses.
So, "IgE receptors" are the proteins located on the surface of cells that bind to IgE antibodies.
