Web Analysis of somatic hypermutation (SHM) and class-switch recombination (CSR) in B-cell receptor rearrangements. Detailed analysis of B-cell receptor rearrangements showed... 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 … See more 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 … See more T cell cytokines modulate class switching in mouse (Table 1) and human (Table 2). These cytokines may have suppressive effect on production of IgM.

WebDec 1, 2014 · Class switch recombination (CSR) is instigated by activation-induced cytidine deaminase, which converts cytosines in switch regions to uracils. The uracils are subsequently removed by two DNA-repair pathways, resulting in mutations, single-strand DNA breaks, and the double-strand breaks required for CSR.

WebSep 17, 2002 · Litinskiy et al. describe a mechanism for CSR that does not require T cell-B cell interaction. Cultured B cells stimulated with exogenous BLyS or APRIL underwent CSR, as detected by small amounts of switch circle DNA, an extrachromosomal product of CSR, and the expression of transcripts from this event. The addition of BLyS or APRIL … WebNov 1, 2007 · Assembly of a functional IgH-IgL protein complex on the cell surface, the so-called B-cell receptor (BCR), allows B cells to escape apoptosis and proceed with maturation. 9 Immature yet immunocompetent B cells expressing surface Ig exit the BM environment and move to the secondary lymphoid organs.
WebNov 9, 2024 · Class switch recombination (CSR) in B cells involves deletion-recombination at switch (S) region DNA and is important for the diversification of antibody isotypes during an immune response. Here, we identify two NME [NM23/NDPK (nucleoside diphosphate kinase)] isoforms, NME1 and NME2, as novel players in this process. WebSep 1, 2008 · CSR, also known as isotype-switching, was first demonstrated in the chicken. 38 A decade after the discovery of RAG1/2, Honjo and his colleagues (Muramatsu et al …

Activation of B cells induces AID and other components of the SHM/class-switch machinery, thus changing the affinity of the BCR and the isotype (IgM to IgG, IgA, or IgE).
