Shared idiotypes and restricted immunoglobulin variable region heavy chain genes characterize murine autoantibodies of various specificities.
The study of the Ig variable region heavy chain (VH) genes used to encode antibodies specific for self-epitopes from murine hybridomas showed that three VH families are primarily utilized: VH J558, the largest family, and VH QPC52 and VH 7183, the families most proximal to the Ig joining region heavy chain genes. These monoclonal autoantibodies express cross-reactive idiotopes shared by rheumat...
متن کاملAutoantibodies encoded by the most Jh-proximal human immunoglobulin heavy chain variable region gene
Little is known about the utilization of human Ig heavy chain variable gene segments (VH segments) in different B-lineage cell populations or in antibodies of particular specificity and function. We now demonstrate that human antibodies with Ig VH regions encoded by the most JH-proximal human VH segment (VH6) have specificities resembling those of autoantibodies present in sera of patients with...
متن کاملDistinct patterns of heavy chain variable region subgroup use by human monoclonal autoantibodies of different specificity
Using a panel of antibodies specific for H and L chain variable region subgroups, a panel of human monoclonal cold agglutinin (CA) and rheumatoid factor (RF) autoantibodies were analyzed. The vast majority of the two types of autoantibodies utilized VkIII L chains, many of which probably derive from the Humkv325 gene. However, while most RFs (77%) utilized VHI H chains, all the CAs used VHII su...
متن کاملReceptor Revision of Immunoglobulin Heavy Chain Variable Region Genes in Normal Human B Lymphocytes
Contrary to the general precepts of the clonal selection theory, several recent studies have provided evidence for the secondary rearrangement of immunoglobulin (Ig) genes in peripheral lymphoid tissues. These analyses typically used transgenic mouse models and have only detected secondary recombination of Ig light chain genes. Although Ig heavy chain variable region (V(H)) genes encode a subst...
متن کاملRecombination between antibody heavy chain variable-region genes: evidence for gene conversion.
The murine hybridoma line B1-8.delta 1 secretes monoclonal IgD lambda 1 antibodies specific for the hapten (4-hydroxy-3-nitrophenyl)acetyl (NP). The variable (V) region of these antibodies is defined by a characteristic pattern of idiotopes. A spontaneous V-region variant (B1-8.V1) with altered idiotope pattern was selected. The structural variation is confined to the V region of the heavy chai...
