Degeneracy of antibody specificity
Journal of Immunology (Baltimore, Md. : 1950)
|August 1, 1983
Summary
Antibodies produced during immunization can bind to unintended targets, suggesting immune response specificity arises from the antibody population, not individual molecules. This challenges traditional views on antibody-antigen interactions.
Area of Science:
- Immunology
- Molecular Biology
- Biochemistry
Background:
- The immune system generates antibodies to specifically target foreign antigens.
- Antibody specificity is traditionally considered a hallmark of individual antibody molecules.
Purpose of the Study:
- To investigate the binding properties of antibodies post-immunization.
- To determine if individual antibody molecules exhibit degenerate binding.
- To understand the basis of immune response specificity.
Main Methods:
- Direct binding assays, including radioimmunoassays.
- Inhibition of binding assays to assess cross-reactivity.
Main Results:
- Evidence indicates that some antibodies produced after immunization bind to both the intended antigen and unrelated ligands.
- This degenerate binding suggests individual antibody molecules are not exclusively specific.
Conclusions:
- Immune response specificity is not solely determined by individual antibody molecules.
- Specificity arises, in part, from the collective binding properties of the antibody population.
- This finding refines our understanding of antibody-antigen interactions and immune recognition.
