title: Characterization of two strains of selectively bred guinea-pigs. 2. Differences in immune response to synthetic polypeptides.
abstract: Two strains of guinea-pigs selectively bred for either high (IMM/S) or low (IMM/R) responsiveness to ovalbumin-induced respiratory anaphylaxis were examined for their immune response to a copolymer of L-glutamic acid and L-alanine (GA), a copolymer of L-glutamic acid and L-tyrosine (GT), and to a dinitro-phenyl derivative of a homopolymer of L-lysine (DNP-PLL). Considerable differences between the strains in development of cellular hypersensitivity and in the production of antibodies were observed. Guinea-pigs from IMM/S were all responders to GA and DNP-PLL and non-responders to GT, while guinea-pigs from two of three lines from IMM/R were responders to GT and non-responders to GA and DNP-PLL. The third IMM/R line showed an immune response pattern similar to guinea-pigs of strain IMM/S. Preliminary breeding studies confirmed that the immune response to these three antigens is under the control of dominant autosomal genes, since (IMM/S x IMM/R) F1 animals responded to all three antigens. It is concluded that these three antigens may serve as immune response markers in genetic studies of the differences between guinea-pigs from IMM/S and IMM/R in their ability to develop respiratory anaphylaxis.
