Immunoglobulin class switching, also known as isotype switching, isotypic commutation or class-switch recombination, is a biological mechanism that changes a B cell's production of immunoglobulin from one type to another, such as from the isotype IgM to the isotype IgG. During this process, the constant-region portion of the antibody heavy chain is changed, but the variable region of the heavy chain stays the same. Since the variable region does not change, class switching does

IgE is also largely associated with hypersensitivity and allergic disorders (2). Indeed, IgE class switching has been reported in the nasal mucosa of patients with aeroallergies [28-31]. With regards to food allergy, IgE antibodies have been detected in stool samples from patients with milk or egg allergy , which suggests that IgE IL-4 signaling promotes IgE class switching through STAT6 activation and the induction of Ig germ-line ε (GLε) transcription. Previously, we and others identified a transcription factor, Nfil3 , as a gene induced by IL-4 stimulation in B cells. However, the precise roles of nuclear factor, IL-3-regulated (NFIL3) in IL-4 signaling are unknown. Here, we report that NFIL3 is important for IgE Sestrin2 Mediates IL-4-induced IgE Class Switching by Enhancing Germline ε Transcription in B Cells You-Sun Shim, 1 Solji Lee, 2 Hwan-Woo Park, 2 and Seok-Rae Park 1 1 Department of Microbiology, Myunggok Medical Research Institute, College of Medicine, Konyang University, Daejeon 35365, Korea.

IgE: Immunoglobulin E Class Human immunoglobulin E (IgE) is expressed on the surface of mature B cells. Human immunoglobulin IgE is the least abundant Ig in the serum and does not activate the complement pathway. Fragment crystallization (Fc) receptors for IgE are found on eosinophils and IgE binds Fc receptors on mast cells and basophils even Abstract. The prevalence of immunoglobulin E (IgE)-mediated allergic diseases has been increasing for the last four decades. In this review determinants for an increased IgE synthesis are discussed on both an epidemiological and on an immunological level with special emphasis on the differentiation of the B cell to an IgE-producing plasma cell.

There are five major immunoglobulin (Ig) classes namely: 1. IgG 2. IgA 3. IgD 4. IgM 5. IgE. Class # 1. IgG: (a) It constitutes 75% of the total serum immunoglobulin in human. (b) During the secondary immune response, it is the major Ig to be synthesized. Hence, it plays a vital role in the defense against infection.
