Abstract/OtherAbstract:
Although both ecto-ADPase and prostacyclin (PGI2) inhibit platelets and neutrophils, their action in acute glomerulonephritis is unknown. We tested the PGI2 analog Iloprost and 2chloroadenosine (2Cl-ADO), an analog of adenosine, the end product of nucleotidase activities, during anti-Thy1 nephritis. Rats received anti-Thy1 immunoglobulin G (5 mg/kg body weight, intravenously) and subsequently one subcutaneous injection of either 2Cl-ADO (10 mg/kg body weight; (n = 6) or Iloprost (1 mg/kg body weight; n = 6). Control rats received anti-Thy1 immunoglobulin G with saline (n = 6) or saline alone (n = 6). After 24 hours, kidneys were processed for light-microscopical evaluation. Proteinuria was studied in additional rats. Results showed that both drugs inhibited intraglomerular platelet activation (P < 0.005). 2Cl-ADO also reduced intraglomerular O2- production of neutrophils (P < 0.05), in contrast to Iloprost. Intraglomerular immunoglobulin G deposition, complement activation, neutrophil influx, and myeloperoxidase release were not affected by 2Cl-ADO or Iloprost. However, proteinuria was completely prevented by both drugs. It is concluded that PGI2 and nucleotidases are potentially able to attenuate this form of nephritis by inhibiting platelet activity, whereas nucleotidases also inhibit neutrophil activity in vivo.
