    Notes: MRL/1 and BXSB mice were treated daily with cyclosporin A (CyA) in an oral dose of 25 mg/kg body weight. With this dose, blood levels within the therapeutic range were obtained. In normal mice CyA in this dose significantly prolonged the survival of an H-2 incompatible skin graft, and suppressed delayed-type hypersensitivity (DTH). It had no influence on the magnitude of a primary antibody response. Autoimmune mice were treated from 6 to 22 weeks of age. CyA treatment did not alter significantly the anti-DNA and anti-IgG autoantibody levels in either strain compared with control mice, who received olive oil. There was a slight but significant increase in serum IgG levels in CyA-treated MRL/1 mice. Clinical signs of glomerulonephritis (decreased kidney function and albuminuria), and glomerular proliferation were not altered by CyA treatment in either strain. The amount of mesangial IgG deposits was reduced in CyA-treated MRL/1 mice, and remained unchanged in BXSB mice. The extent of the interstitial and perivascular infiltrates and the frequency and severity of necrotizing arteritis in the kidneys of MRL/1 mice were reduced by CyA treatment. The most prominent effect of CyA was an evident reduction in lymphoproliferation in MRL/1 mice. Mortality was not reduced by CyA treatment in MRL/1 and BXSB mice.

    Notes: The Raji-cell test is one of the most widely used methods for the detection and quantitation of immune complexes. Immune complexes and not 7 S IgG bind via C3 to complement receptors on the cell membrane of the Raji cell. During sucrose gradient fractionation of human and murine systemic lupus erythematosus sera, with a high Raji cell-binding activity, we could not demonstrate immune complexes in these sera. Subsequent analysis showed that the major part of the Raji cell binding was used by 7 S IgG with an anti-DNA specificity. Blocking experiments wilh complement-bearing aggregated IgG revealed that complement and Fc receptors were not involved in the binding of these anti-DNA antibodies to Raji cells. We conclude that the Raji cell test is not suitable for the detection and quantitation of immune complexes in sera containing anti-DNA antibodies.

    Notes: Summary The induction of experimental arthritis in rhesus monkeys was studied by intradermal immunization of bovine type II collagen and antigens derived fromMycobacterium tuberculosis, Streptococcus pyogenes, andEubacterium aerofaciens. The tested bacterial antigens proved to be not arthritogenic. Bovine type II collagen induced clinical arthritis in 50% of the rhesus monkeys. Type II collagen induced arthritis in rhesus monkeys proved to be a potential model to study clinical, serological, histological, genetic, and immunologic features associated with human RA.
