Guinea pig histocompatibility antigens. III. Analysis of normal lymphocyte transfer (NLT) reactions among guinea pigs with serologically defined phenotypes (GPL-AB locus and I region). 1976

K J Tötterman, and E Müller, and A L de Weck

The normal lymphocyte transfer (NLT) reaction occurring upon intradermal injection of lymphocytes into a normal recipient may be considered as a kind of mixed lymphocyte reaction in vivo. In previous experiments, we have defined serologically a number of guinea pig lymphocyte antigens, controlled either by a GPL-A locus (equivalent of H-2 D locus in mice) or by a so-called I region (equivalent to the I region in mice). The I region also appears to control a number of immune response genes in the guinea pig. Using guinea pig inbred strains (such as 2, 13, OM3, BE), guinea pig families homozygous for their GPL-A antigens and serologically characterized outbreds, it has been possible to show that antigens of the I region probably play a higher role in NLT reactions. No NLT reactions occur among outbred animals of a closed colony which have been bred to homozygozity for their GPL-A antigens and thereby probably possess haplotype homozygozity for their major histocompatibility complex. The NLT reaction among serologically characterized guinea pigs may become a convenient way to detect new specificities and recombinant progeny.

UI MeSH Term Description Entries
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D005838 Genotype The genetic constitution of the individual, comprising the ALLELES present at each GENETIC LOCUS. Genogroup,Genogroups,Genotypes
D006168 Guinea Pigs A common name used for the genus Cavia. The most common species is Cavia porcellus which is the domesticated guinea pig used for pets and biomedical research. Cavia,Cavia porcellus,Guinea Pig,Pig, Guinea,Pigs, Guinea
D006649 Histocompatibility Antigens A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection. Transplantation Antigens,Antigens, Transplantation,Histocompatibility Antigen,LD Antigens,SD Antigens,Antigen, Histocompatibility,Antigens, Histocompatibility,Antigens, LD,Antigens, SD
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D012882 Skin Tests Epicutaneous or intradermal application of a sensitizer for demonstration of either delayed or immediate hypersensitivity. Used in diagnosis of hypersensitivity or as a test for cellular immunity. Skin Test,Test, Skin,Tests, Skin
