Elucidation of the enigmatic IgD class-switch recombination via germline deletion of the IgH 3′ regulatory region
Classical class-switch recombination (cCSR) substitutes the Cμ gene with Cγ, Cε, or Cα, thereby generating IgG, IgE, or IgA classes, respectively. This activation-induced deaminase (AID)-driven process is controlled by the IgH 3' regulatory region (3'RR). Regulation of rare IgD CSR events has been enigmatic. We show that μδCSR occurs in mouse mesenteric lymph node (MLN) B cells and is AID-depen...

15 صفحه اولReduced immunoglobulin class switch recombination in the absence of Artemis.
Nonhomologous end-joining DNA repair factors, including Artemis, are all required for the repair of DNA double-strand breaks, which occur during the assembly of the variable antigen recognition domain of B-cell receptors and T-cell receptors through the V(D)J recombination. Mature B cells further shape their immunoglobulin repertoire on antigen recognition notably through the class switch recom...
متن کاملIGH switch breakpoints in Burkitt lymphoma: exclusive involvement of noncanonical class switch recombination.
Most chromosomal t(8;14) translocations in sporadic Burkitt lymphomas (BL) are mediated by immunoglobulin class switch recombination (CSR), yet all tumors express IgM, suggesting an incomplete or exclusively monoallelic CSR event. We studied the exact configuration of both the nontranslocated IGH allele and the MYC/IGH breakpoint by applying a combination of low- and high-resolution methods (in...
متن کاملQuantitative Regulation of Class Switch Recombination by Switch Region Transcription
The isotype specificity of immunoglobulin (Ig) class switching is regulated by a cytokine which induces transcription of a specific switch (S) region, giving rise to so-called germline transcripts. Although previous studies have demonstrated that germline transcription of an S region is required for class switch recombination (CSR) of that particular S region, it has not been shown whether the ...
