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… WebCytokines are subclassified as interleukins (ILs), tumor necrosis factors (TNFs), interferons, and colony-stimulating factors. Examples from the family of cytokines are detailed in Table 1. All influence cells of the immune system; however, only …
