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 کاملImmunoglobulin heavy chain constant regions regulate immunity and tolerance to idiotypes of antibody variable regions.
Particular syngeneic adjuvant-free monoclonal antibodies are immunogenic and elicit antibody responses against the variable region idiotypes (Ids). We here study how heavy-chain constant regions (C(H)) regulate immune responses to Ids of free, uncomplexed monoclonal antibodies. To this end, we selected two hybridomas, called Id(3) and Id(A.01), that produce immunogenic IgM(lambda)2 directed tow...
متن کاملDevelopmental progression of equine immunoglobulin heavy chain variable region diversity.
Humoral immunity is a critical component of the immune system that is established during fetal life and expands upon exposure to pathogens. The extensive humoral immune response repertoire is generated in large part via immunoglobulin (Ig) heavy chain variable region diversity. The horse is a useful model to study the development of humoral diversity because the placenta does not transfer mater...
متن کاملStructure and multiplicity of genes for the human immunoglobulin heavy chain variable region.
Several genes for the variable region of immunoglobulin heavy chains (VH genes) have been isolated from human fetal liver DNA by using a cDNA plasmid probe containing a mouse VH sequence. The detectable VH genes are separated by 12-16 kilobases of DNA, and hybridization experiments show about 23 hybridizing VH genes in DNA of three different individuals. The complete nucleotide sequence of one ...
