Molecularly, switching to IgE can proceed directly from IgM to IgE or sequentially from IgM to IgG1 and then to IgE ( Siebenkotten et al., 1992 ). In addition, treatments that ablate IgE + B cells and short-lived plasmablasts (e.g., membrane IgE depleting antibody) or prevent class switching to IgE [e.g., interleukin-4 (IL-4)/IL-13 blocking antibodies] reduce serum IgE but are unable to bring serum IgE back to baseline (17–20), indicating the presence of an IgE serological memory source that cannot be efficiently targeted with Immunoglobulin class switching, also known as isotype switching, isotypic commutation or class-switch recombination (CSR), 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 patients B-cell IgE class switching usually occurs in TLSs such as nasal polyps or inducible bronchial-associated lymphoid clusters [28, 30]. The aim of this work was to clarify the hypothesis that B-cell IgE class switching in response to low, but not high, administrated antigen doses occurs mostly in the specific milieu of TLSs but not in SLOs.

Mice deficient in IgG1 production cannot produce high affinity IgE, even after repeated immunizations. After confirming the importance of sequential class switching to IgE for the affinity maturation of two different antigen-driven T cell–dependent responses, we investigated the role of sequential switching to a known polyclonal stimulator of IgE and IgG1 production, anti-IgD serum (Finkelman et al., 1989). 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. Noncoding transcripts originating upstream of the immunoglobulin constant region (I transcripts) are required to direct activation-induced deaminase to initiate class switching in B cells. Differential regulation of Iε and Iγ1 transcription in response to interleukin 4 (IL-4), hence class switching to IgE and IgG1, is not fully understood. 2018-12-05 · We investigated the specific role of STAT3 in the germinal center (GC) B cells and plasma cells for IgE class switching. Through the use of STAT3 conditional knockout (cKO) mice in a Th2-type immunization model, we demonstrated that CD2-Cre-driven STAT3 cKO mice showed elevated IgE and decreased IgG1 in the serum and a reduction in GC formation.
