Natural thymocytotoxic autoantibodies in autoimmune and normal mice. 1979

R A Eisenberg, and A N Theofilopoulos, and B S Andrews, and C J Peters, and L Thor, and F J Dixon

Natural thymocytotoxic autoantibodies (NTA) were found in all mouse strains. Among those strains that show autoimmune syndromes resembling human systemic lupus erythematosus (SLE), the NZB and NZBxNZW had high levels of NTA, the BXSB had moderate levels, and the MRL/1 and MRL/n had very low levels. In addition, some normal strains had high levels, sometimes even higher than the autoimmune strains. The NTA were mostly IgM and were present, but not concentrated, in the cryoprecipitates of teh autoimmune mouse strains. In most strains, they were directed toward an antigen shared by thymocytes and brain. The failure to find high levels of NTA in all autoimmune mouse strains, as well as the finding of very high levels in some normal strains, make it unlikely that such auto-antibodies are a fundametnal etiologic factor in all murine SLE.

D007070 Immunoglobulin A Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions. IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007074 Immunoglobulin G The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B. Gamma Globulin, 7S,IgG,IgG Antibody,Allerglobuline,IgG(T),IgG1,IgG2,IgG2A,IgG2B,IgG3,IgG4,Immunoglobulin GT,Polyglobin,7S Gamma Globulin,Antibody, IgG,GT, Immunoglobulin
D007075 Immunoglobulin M A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin. Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D008297 Male Males
D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D008814 Mice, Inbred NZB An inbred strain of mouse that is widely used as a model for AUTOIMMUNE DISEASES such as SYSTEMIC LUPUS ERYTHEMATOSUS. Mice, NZB,Mouse, Inbred NZB,Mouse, NZB,Inbred NZB Mice,Inbred NZB Mouse,NZB Mice,NZB Mice, Inbred,NZB Mouse,NZB Mouse, Inbred
D003450 Cryoglobulins Abnormal immunoglobulins, especially IGG or IGM, that precipitate spontaneously when SERUM is cooled below 37 degrees Celsius. It is characteristic of CRYOGLOBULINEMIA. Cryoglobulin,Cryoprotein,Cryoproteins
D003602 Cytotoxicity, Immunologic The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitized T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement.

D005260 Female Females
D000042 Absorption The physical or physiological processes by which substances, tissue, cells, etc. take up or take in other substances or energy.
