Abstract:

Two novel murine monoclonal antibodies (mAbs) were produced to the Thy-1 molecule of Mongolian gerbils (Meriones unguiculatus). These mAbs, HUSM-M. g.27 of IgG1 isotype and HUSM-M. g.40 of IgG2a isotype, immunohistochemically reacted with the thymus, nervous system, and glomerular mesangium in partially different manners, suggesting that they recognize distinct epitopes, although they reacted with Thy-1 antigen, with apparent molecular weight of about 25 kDa, on gerbil thymocytes. Mild and severe forms of mesangioproliferative nephritis after glomerular deposition of the antibody was observed in gerbils administered mAbs HUSM-M. g.27 and HUSM-M. g.40, respectively, intraperitoneally, with or without guinea-pig serum as supplementary complement. Distinct pathogenicity and requirement of guinea pig serum for pathologic sequels are discussed as they relate to the rat model of anti-Thy-1-induced glomerulonephritis.
