PG - 387-94 AB - Renal lesions of rats induced by antibodies to cultured rat glomerular epithelial cells (GEC) and mesangial cells (GMC) were studied. Antibodies to cultured rat GEC and GMC were produced by immunization of rabbits with GEC and GMC respectively. The rats injected with anti-GEC antibody showed a small amount of urinary protein, glomerular deposition of rabbit IgG and subepithelial dense deposits observed by electron microscopy. Proteinuria was suppressed in the rats in which complement was depleted with cobra venom factor. Western blot analysis demonstrated a band of 200 KD in GEC lysates reacted with anti-GEC antibody. The rats injected with anti-GMC antibody showed little urinary protein, glomerular deposition of rabbit IgG and mesangial dense deposits. Western blot analysis demonstrated two bands of 43 and 14 KD in GMC lysates reacted with anti-GMC antibody. These data showed that the injection of anti-GEC antibody or anti-GMC antibody induced similar lesions to passive Heymann nephritis and anti Thy 1.1 nephritis. This study suggested that antigenicity of structural glomerular cells is important as the antigens of glomerulonephritis.
