Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin (Ig) "isoform") that has been found only in mammals. IgE is synthesised by plasma cells. Monomers of IgE consist of two heavy chains (ε chain) and two light chains, with the ε chain containing four Ig-like constant domains (Cε1–Cε4). [1]
The high-affinity IgE receptor, also known as FcεRI, or Fc epsilon RI, is the high-affinity receptor for the Fc region of immunoglobulin E (IgE), an antibody isotype involved in allergy disorders and parasite immunity. FcεRI is a tetrameric receptor complex that binds Fc portion of the ε heavy chain of IgE. [1]
Anti-IgE [huMaE11 (Omalizumab)] is used in drugs that treat allergies and asthma. [16] Anti-IgE [TES-C21] This is a recombinant monoclonal antibody to IgE. The anti-IgE antibody binds specifically to IgE antibodies by B cells (interleukins Il-4 and IL-13). Anti-IgE can be conjugated to cytotoxic drugs in order to deliver them to IgE-producing B ...
Quantitative IgE test results increase the possibility of ranking how different substances may affect symptoms. A rule of thumb is that the higher the IgE antibody value, the greater the likelihood of symptoms. Allergens found at low levels that today do not result in symptoms cannot help predict future symptom development.
According to this system, known as the Gell and Coombs classification [6] or Gell-Coombs's classification, [7] there are four types of hypersensitivity, namely: type I, which is an Immunoglobulin E (IgE) mediated immediate reaction; type II, an antibody-mediated reaction mainly involving IgG or IgM; type III, an immune complex-mediated reaction ...
Schematic diagram of a typical antibody showing two Ig heavy chains (blue) linked by disulfide bonds to two Ig light chains (green). The constant (C) and variable (V) domains are shown. An antibody molecule. The two heavy chains are colored red, blue, and purple. The two light chains green and yellow. See also:

Interleukin 4 mediates important pro-inflammatory functions in asthma, including induction of isotype rearrangement of IgE, expression of vascular cell adhesion molecule 1 (VCAM-1), promoting eosinophilic transmigration through endothelium, mucus secretion and T helper type 2 (T h 2) leading to cytokine release. Asthma is a complex genetic ...
