Tetraparental rabbits chimeric for their lymphoid system--II. Idiotype expression
Molecular Immunology
|May 1, 1984
Summary
Tetraparental rabbits revealed that distinct antibody populations can develop independently. However, prior anti-anti-idiotypic immunization suggests potential for related idiotypic specificities in network theory interactions.
Area of Science:
- Immunology
- Network Theory
- Antibody Specificity
Background:
- The network theory of idiotype-anti-idiotype interactions proposes complex regulatory mechanisms in the immune system.
- Understanding these interactions is crucial for deciphering immune repertoire development and regulation.
Purpose of the Study:
- To investigate the influence of experimental conditions on idiotypic specificities of anti-DNP antibodies in tetraparental rabbits.
- To test predictions of the network theory regarding immune system interactions.
Main Methods:
- Utilized tetraparental rabbits, chimeric for their lymphoid systems.
- Employed two immunization strategies: direct anti-hapten immunization and anti-anti-idiotypic immunization followed by anti-hapten immunization.
- Analyzed idiotypic specificities of produced anti-DNP antibodies, considering allotypic differences.
Main Results:
- Under direct anti-hapten immunization, antibodies from distinct parental lymphocyte populations remained idiotypically independent.
- Following anti-anti-idiotypic immunization, a subset of anti-DNP antibodies with differing allotypes exhibited related idiotypic specificities.
- Observed related idiotypic specificities in 2 out of 4 cases after the second experimental regimen.
Conclusions:
- The immune system's network interactions can lead to both independent and related idiotypic specificities depending on immunization protocols.
- Findings provide evidence supporting and refining aspects of the network theory of idiotype-anti-idiotype interactions.
- Suggests that immune system priming can influence the development of shared idiotypic features among diverse antibody populations.

01:39Epistasis
50.5K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

17.9K
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

1.8K
Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
