Idiotope Ac38, a V region determinant of the lambda 1 chain‐bearing, germ line encoded antibody B1‐8, is expressed at high frequency (approximately 1/40) in lambda 1 chain‐bearing B cells. Here, we describe the isolation of lambda‐positive hybridomas from C57BL/6 mice which had been immunized with antibody Ac38, the antibody recognizing idiotope Ac38. In Northern blot analysis, mRNA isolated from 10 such hybridomas hybridizes with a cDNA probe from the VH gene expressed in the cell line B1‐8… 
Genetic basis for expression of the idiotypic network. One unique Ig VH germline gene accounts for the major family of Ab1 and Ab3 (Ab1') antibodies of the GAT system
TLDR
The previous hypothesis that NPa and GAT VH genes were derived from the same germline gene was definitively confirmed, both from sequence data and Southern blot analysis.
A single VH-gene associated with a variety of D- and J-segments encodes for a large family of ABPC48-related antibodies induced by antiidiotypic immunization.
TLDR
This study indicates that the identification of idiotype-related antibodies arising from antiidiotypic immunization may be misleading, if based on their antigen-binding properties; and it stresses the importance of structural approaches for the analysis of regulatory mechanisms ruling immune responses.
Somatic hypermutation and germline evolution of immunoglobulin variable genes
TLDR
This data set indicates that almost 97 % of somatic mutations were found downstream of the transcription start site (cap) site, and that the mutation frequency distribution around IgVn regions is asymmetrical, with a single mode centered on the rearranged V H region and a long tail extending into the J C intron.
Variable region gene segments of nine monoclonal antibodies specific to disialogangliosides (GD2, GD3) and their O-acetylated derivatives.
TLDR
Results clearly indicate that MAbs directed to very similar structures as GD2 and GD3 were encoded by different VH and V kappa genes.
Idiotypic Replica of an Anti‐Human Tumour‐Associated Antigen Monoclonal Antibody DNA Sequence Comparison between Ab1 and Ab3
2G‐3 is an anti‐anti‐idiotypic MoAb (Ab3) obtained upon immunization wiih a monoclonal Ab2 (A3B10), which behaves as the “internal image” of CaMBrl. a saccharidic epitope defined by MoAb MBrl (Abl),
The molecular genetics of the arsonate idiotypic system of A/J mice.
TLDR
This chapter focuses on the antibodies produced by A/J mice in response to immunization with the hapten p-azophenylarsonate, an artificial immunogen coupled to keyhole limpet hemocyanin (Ars-KLH).
The internal image and the structural idiotypic network (Ab1, Ab2, Ab3) in the GAT system.
TLDR
The GAT repertoire expressed at the different levels of the classical idiotypic cascade Ag----Ab1----Ab2----Ab3 has been analysed by direct nucleotide sequencing of H- and L-enriched mRNA and it is suggested that this D region contains the internal image of the antigen.
Timing, Genetic Requirements and Functional Consequences of Somatic Hypermutation during B‐Cell Development
TLDR
By constructing an antibody mutant through site-specific mutagenesis, it is shown that a point mutation in CDR1 of the heavy chain, found in most secondary anti-NP antibodies, is sufficient to increase NP binding affinity to the level typical for the secondary response.
Novel cross-reactive anti-idiotype antibodies with properties close to the human intravenous immunoglobulin (IVIg).
TLDR
Both anti-idiotype MAbs showed anti-metastatic effect in vivo when injected intravenously to mice inoculated with MB16-F10 melanoma cells, and can become an interesting tool for further exploration of the role of idiotypic network connections in the regulation of the immune system.
Regulation of the response to alpha(1-3) dextran: an anti-dextran associated idiotope of BALB/c mice is also expressed on A/J anti-NIP antibodies.
TLDR
The B5 id appears as a typical id determinant shared by antibodies having different binding specificities, and it may have a role in the regulation of these responses.
