title: Identification of anti-idiotypic antibody in dogs.
abstract: There is general agreement that idiotype/anti-idiotype (id/anti-id) networks are important mechanisms of immune regulation, based primarily on studies conducted using inbred laboratory animals. To determine if anti-idiotypic antibody (anti-id) could be induced during an immune response in outbred dogs, the dogs were immunized to the hapten-carrier combination dinitrophenol-ascaris (DNP-ASC) and subsequently immunized with autologous antibody in complete Freund's adjuvant (CFA). Auto-anti-id was detected in three of five dogs during the DNP-ASC response. A cross-reactive anti-id was detected in dogs immunized with autologous antibody when a mouse monoclonal antibody was used as the id. These experiments further suggest that the regulation of the immune response via network interaction, as first illucidated in inbred animals, may occur in dogs.
