Binding of CLL Subset 4 B Cell Receptor Immunoglobulins to Viable Human Memory B Lymphocytes Requires a Distinctive IGKV Somatic Mutation
1 Jan 2017
Abstract excerpt
Amino acid replacement mutations in certain chronic lymphocytic leukemia (CLL) stereotyped B cell receptor (BCR) immunoglobulins (IGs) at defined positions within antigen-binding sites strongly imply antigen selection. Prime examples of this are CLL subset 4 BCR IGs using IGHV4-34/IGHD5-18/IGHJ6 and IGKV2-30/IGKJ2 rearrangements. Conspicuously, and unlike most CLL IGs, subset 4 IGs do not bind apoptotic cells.
