During a germinal center reaction, random mutations are introduced into immunoglobulin V genes to increase the affinity of antibody molecules and to further diversify the B cell repertoire. Antigen-directed selection of B cell clones that generate high affinity surface Ig results in the affinity maturation of the antibody response. The mutations of Ig genes(More)
Previous work has shown that, after domestic chicks have learned the characteristics of an object (visual imprinting), there is a learning-related increase in the numerical density of Fos-immunopositive neurons in the intermediate and medial part of the hyperstriatum ventrale, a forebrain region that is a site of recognition memory for the imprinted object.(More)
Dysregulated expression of factors that control protein synthesis is associated with poor prognosis of many cancers, but the underlying mechanisms are not well defined. Analysis of the diffuse large B-cell lymphoma (DLBCL) translatome revealed selective upregulation of mRNAs encoding anti-apoptotic and DNA repair proteins. We show that enhanced synthesis of(More)
The anti-idiotypic (anti-Id) antibody (Ab) 9G4 binds a cross-reactive idiotope (CRI) present in a select group of human autoantibodies. This Id has been localized to the portion of immunoglobulin (Ig) heavy (H) chains encoded by the V,4-21 gene segment, a member of the human V.4 family. This gene segment is utilized by essentially all cold agglutinin (CA)(More)
Expression of surface immunoglobulin appears critical for the growth and survival of B-cell lymphomas. In follicular lymphoma, we found previously that the Ig variable (V) regions in the B-cell receptor express a strikingly high incidence of N-glycosylation sequons, NX(S/T). These potential glycosylation sites are introduced by somatic mutation and are(More)
Cancer immunotherapy has been revolutionised by the use monoclonal antibodies (mAb) that function through their interaction with Fc gamma receptors (FcγRs). The low-affinity FcγR genes are highly homologous, map to a complex locus at 1p23 and harbour single nucleotide polymorphisms (SNPs) and copy number variation (CNV) that can impact on receptor function(More)

A comprehensive DNA analysis computer program was described in the second special issue of Nucleic Acids Research on the applications of computers to research on nucleic acids by Stone and Potter (1). Criteria used in designing the program were user friendliness, ability to handle large DNA sequences, low storage requirement, migratability to other(More)
A program designed for DNA sequence analysis by people with no computer background or experience is described. The criteria used in the program design were (i) user friendliness, (ii) ability to handle large DNA files (greater than 10 kilobases), (iii) low storage requirements so that it could be put on a personal computer (IBM), (iv) written in a widely(More)
