High-frequency representation of a single VH gene in the expressed human B cell repertoire [published erratum appears in J Exp Med 1993 Apr 1;177(4):following 1226]
Idiotype (Id) 16/6 marks a variable (V) region structure that occurs frequently in the human immunoglobulin repertoire. The basis of the Id has been traced to a germline heavy chain gene segment, VH18/2 (VH26). To pursue the molecular basis for the frequency of Id 16/6, we have analyzed polymerase chain reaction-generated C mu, C gamma, and VH3 family V gene libraries derived from the circulati...
متن کاملP-215: Discovery of A Novel APA Variant of A Human Potential Gene Based on Expressed Sequenced Tags Analysis
Background: Expressed sequence tags (ESTs) are sequences of cDNA fragments prepared from different tissue sources. There are over one million of these sequences in the publicly available database, and these sequences are believed to represent more than half of all human genes. The ESTs belong to different cDNA libraries, was prepared from one particular cell type, organ, or tumor. Therefore, th...
متن کاملThe VH gene repertoire of splenic B cells and somatic hypermutation in systemic lupus erythematosus
In systemic lupus erythematosus (SLE) it has been hypothesized that self-reactive B cells arise from virgin B cells that express low-affinity, nonpathogenic germline V genes that are cross-reactive for self and microbial antigens, which convert to high-affinity autoantibodies via somatic hypermutation. The aim of the present study was to determine whether the VH family repertoire and pattern of...
متن کاملAntibody repertoire diversification through VH gene replacement in mice cloned from an IgA plasma cell.
In mammals, VDJ recombination is responsible for the establishment of a highly diversified preimmune antibody repertoire. Acquisition of a functional Ig heavy (H) chain variable (V) gene rearrangement is thought to prevent further recombination at the IgH locus. Here, we describe VHQ52(NT); Vκgr32(NT) Ig monoclonal mice reprogrammed from the nucleus of an intestinal IgA(+) plasma cell. In VHQ52...
متن کاملHigh frequency of somatic mutations in the VH genes expressed in prolymphocytic leukemia.
Prolymphocytic leukemia (PLL) is a chronic lymphoproliferative disorder, characterized by prominent splenomegaly, prolymphocytes accounting for more than 55% of circulating lymphocytes, and short-term survival. To better characterize the nature of the cellular origin in this disease, we analyzed lg heavy chain variable region (VH) genes in eleven cases of de novo PLL Leukemic cells expressed a ...
