Functional Immunoglobulin Light Chain Genes
Rearrangement of Ig genes proceeds during B cell differentiation in an orderly fashion. First the heavy (H) chain gene is rearranged in pre-B cells . These cells can express cytoplasmic A chain but no light (L) chain (1). The K light chain genes rear range next and if they fail to produce a functional gene on either chromosome the X light chain genes are rearranged (2) . It is generally believe...
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 ...
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 کاملShared 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 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...
