title: Production of idiotypic and anti-idiotypic antibodies by BALB/c mice in response to immunizations with glucagon, vasopressin, or insulin: supporting evidence for the network concept.
abstract: After immunizations with glucagon or vasopressin, either conjugated to keyhole limpet hemocyanin or adsorbed to polyvinylpyrrolidone, both anti-hormone and anti-receptor activities were detectable in the serum of injected mice. Anti-hormone activity was identified by ELISA techniques; anti-receptor activity, by determining the ability of serum samples to compete with labeled hormone for glucagon or vasopressin receptors on rat liver plasma membranes. Anti-receptor activity appeared only after the peak anti-hormone response to each immunogen had been established, and required intensive immunizations (six to nine monthly injections). The presence of anti-idiotypic antibodies in serum samples containing glucagon or vasopressin anti-receptor activity was confirmed by demonstrating selective binding of such samples to corresponding rabbit idiotypic antibodies. Serum from mice immunized with insulin also contained anti-hormone activity, as determined by ELISA, and anti-receptor activity, as determined by noting insulin-mimicking properties in stimulating glucose transport in rat adipocytes. The anti-insulin receptor activity developed after only one boost with the hormone. These results are consistent with Jerne's network hypothesis in that the glucagon, vasopressin, and insulin anti-receptor activity may be attributed to antibodies produced in mice as part of an idiotypic-anti-idiotypic network.
