WebDec 24, 2024 · Immunoglobulin class switching (or isotype switching, or isotypic commutation, or class switch recombination (CSR)) is a biological mechanism that changes a B cell’s production of antibody from one class to another; for example, from an isotype … WebThis Ig class switch is based on a deoxyribonucleic acid (DNA) recombination event that results in an exchange of the gene segments coding for the constant region of the Ig heavy chain, although the Ig heavy chain variable region is retained. This process changes the effector functions of the corresponding antibody (Ab).
IgH Chain Class Switch Recombination: Mechanism and Regulation
WebThis Ig class switch is based on a deoxyribonucleic acid (DNA) recombination event that results in an exchange of the gene segments coding for the constant region of the Ig heavy chain, although the Ig heavy chain variable region is retained. This process changes the effector functions of the corresponding antibody (Ab). WebFeb 7, 2024 · The range of reactivity of the primary immunoglobulin repertoire can be further modified by somatic hypermutation (SHM) and class switch recombination (CSR) at the immunoglobulin loci. SHM results in mutations being introduced into the V region of the heavy chain and light chain, altering the affinity of the immunoglobulin for its antigen. remembrance day video for kids uk
Mouse Homolog of Saccharomyces cerevisiae Spo11 Is
WebAug 1, 2001 · Recently, we showed that mouse Spo11 is induced in normal μ(+) B cells by class switch recombination (CSR) stimuli, by RT–PCR using primers based on the reported cDNA sequence of testis-derived Spo11 (test-Spo11) cDNA. In the present study, we first … WebB cells have the unique property to somatically alter their immunoglobulin (IG) genes by V(D)J recombination, somatic hypermutation (SHM) and class-switch recombination (CSR). Aberrant targeting of these mechanisms is implicated in lymphomagenesis, but the mutational processes are poorly understood. … WebIg class switching involves deletions of germline DNA resulting in religation of the VDJ complex to downstream heavy chain C region genes, such as γ3, γ1 γ2b, γ2a, ε, and α.
