Age-related changes in cell surface antigens of preleukemic AKR thymocytes. 1976

K Kawashima, and H Ikeda, and E Stockert, and T Takahashi, and L J Old

Thymocytes from preleukemic AKR mice aged 5-6 mo have an altered pattern of cell surface antigens. The expression of four MuLV-related antigens on the cell surface (GIX, GCSA, gp70, p30) is markedly increased in comparison to 2-mo-old AKR mice and approximates the heightened levels of these antigens found on thymic leukemia cells. H-2 and Thy-1 alloantigens also show characteristic modifications in relation to age and leukemia development. In contrast to the high Thy-1/low H-2 levels on 2-mo-old AKR thymocytes, thymocytes from 6-mo-old mice and thymic leukemia cells frequently show a low Thy-1/high H-2 surface phenotype. As thymocytes from mouse strains with a low incidence of leukemia do not show these changes, they appear to represent a stage in the conversion of normal cells to leukemia cells.

UI MeSH Term Description Entries
D007519 Isoantigens Antigens that exist in alternative (allelic) forms in a single species. When an isoantigen is encountered by species members who lack it, an immune response is induced. Typical isoantigens are the BLOOD GROUP ANTIGENS. Alloantigens,Alloantigen,Isoantigen
D007942 Leukemia, Experimental Leukemia induced experimentally in animals by exposure to leukemogenic agents, such as VIRUSES; RADIATION; or by TRANSPLANTATION of leukemic tissues. Experimental Leukemia,Experimental Leukemias,Leukemia Model, Animal,Leukemias, Experimental,Animal Leukemia Model,Animal Leukemia Models,Leukemia Models, Animal
D008806 Mice, Inbred AKR An inbred strain of mouse that is widely used in IMMUNOLOGY studies and cancer research. Mice, AKR,Mouse, AKR,Mouse, Inbred AKR,AKR Mice,AKR Mice, Inbred,AKR Mouse,AKR Mouse, Inbred,Inbred AKR Mice,Inbred AKR Mouse
D009052 Leukemia Virus, Murine Species of GAMMARETROVIRUS, containing many well-defined strains, producing leukemia in mice. Disease is commonly induced by injecting filtrates of propagable tumors into newborn mice. Graffi Virus,Graffi's Chloroleukemic Strain,Leukemia Viruses, Murine,Mouse Leukemia Viruses,Murine Leukemia Virus,Murine Leukemia Viruses,Graffi Chloroleukemic Strain,Graffis Chloroleukemic Strain,Leukemia Viruses, Mouse
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
D000375 Aging The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time. Senescence,Aging, Biological,Biological Aging
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
D000951 Antigens, Neoplasm Proteins, glycoprotein, or lipoprotein moieties on surfaces of tumor cells that are usually identified by monoclonal antibodies. Many of these are of either embryonic or viral origin. Neoplasm Antigens,Tumor Antigen,Tumor Antigens,Antigen, Tumor,Antigens, Tumor
D000956 Antigens, Viral Substances elaborated by viruses that have antigenic activity. Viral Antigen,Viral Antigens,Antigen, Viral
D013499 Surface Properties Characteristics or attributes of the outer boundaries of objects, including molecules. Properties, Surface,Property, Surface,Surface Property
