Cytokines involved in class switching
WebSomatic hypermutation (or SHM) is a cellular mechanism by which the immune system adapts to the new foreign elements that confront it (e.g. microbes ), as seen during class switching. A major component of the process of affinity maturation, SHM diversifies B cell receptors used to recognize foreign elements ( antigens) and allows the immune ...

WebSep 1, 2003 · Several cytokines regulate IgE class switching, either by regulating the production of T H 2-type cytokines and/or regulating the effect of these cytokines on Cε …
Class switching occurs after activation of a mature B cell via its membrane-bound antibody molecule (or B cell receptor) to generate the different classes of antibody, all with the same variable domains as the original antibody generated in the immature B cell during the process of V(D)J recombination, but possessing distinct constant domains in their heavy chains. Naïve mature B cells produce both IgM and IgD, which are the first two heavy chain segments in t… WebIgA is the most abundant antibody class and provides a first line of defence at mucosal surfaces. Class switching to IgA occurs through both T-cell-dependent and T-cell-independent pathways, and ...
