Histocompatibility type and immune responsiveness in random bred Hartley strain guinea pigs.

Outbred Hartley strain guinea pigs capable of responding immunologically to 2,4-dinitrophenylated poly-L-lysine were shown to display a histocompatibility specificity in common with inbred strain 2 guinea pigs. This histocompatibility specificity was not detected in guinea pigs unable to respond immunologically to DNP-PLL. The result suggests that the poly-L-lysine specific immune response gene is very closely linked or even identical with a gene determining a major histocompatibility antigen in guinea pigs.

Genetically controlled total deficiency of the fourth component of complement in the guinea pig.

Guinea pigs with a total deficiency of the fourth component of complement (C4) have been discovered. There was no evidence for the presence of a C4 inhibitor in the serum of these animals. Mating studies indicate that C4 deficiency is transmitted as a simple autosomal recessive trait. A colony of these animals is being established at the National Institutes of Health. They will provide an opportunity to more precisely define the role of complement in immune phenomena and the defense against disease.

Linkage between the poly-L-lysine gene and the locus controlling the major histocompatibility antigens in strain 2 guinea pigs.

The data presented demonstrate linkage between the major histocompatibility locus of inbred strain 2 guinea pigs and a "specific immune response gene," the PLL gene, which controls responsiveness to poly-L-lysine and hapten conjugates of this polypeptide in these animals. This finding extends to another species and to a different immune system the linkage observed in mice between the H(2) locus and specific immune response genes at the Ir-1 locus. The general significance of the linkage of specific immune response genes to histocompatibility loci is discussed.

Genetic control of the immune response of guinea pigs to limiting doses of bovine serum albumin: relationship to the poly-L-lysine gene.

The response of strain 2 guinea pigs to limiting doses of bovine serum albumin is under dominant genetic control linked with the poly-L-lysine gene. Inbred strains 2 and 13 guinea pigs make similar antibody responses to 10 mug bovine serum albumin, whereas strain 2 but not strain 13 animals produce significant amounts of antibodies in response to 0.1 mug. The relationship between the presence of the poly-L-lysine gene and the ability to respond to limiting doses of bovine serum albumin has also been investigated in random-bred Hartley strain guinea pigs.
