    Abstract:
    The role of Platelet Activating Factor (PAF) in experimental immune glomerulonephritis was assessed by administering the specific PAF receptor antagonist CV-3988 to inbred LEW rats with the Accelerated Autologous Nephrotoxic Serum Nephritis (AA-NTSN). Intravenous administration of CV-3988 caused a marked and sustained reduction in albuminuria and renal histopathological changes. Conversely, although CV-3988 appeared to modulate the fall in glomerular filtration rate (GFR) in the AA-NTSN, this trend was not statistically significant. Renal glomeruli isolated on day 1 after nephritis induction spontaneously released 16.9 +/- 2.2 ng of PAF per 200 glomeruli, while in glomeruli of healthy rats this secretion was virtually undetectable. The administration of CV-3988 to rats with AA-NTSN did not affect the following: binding of intravenously injected sheep anti-rat glomerular basement membrane (GBM) antibody; levels of autologous antibody to sheep immunoglobulin G; the functional integrity of circulating neutrophils. We conclude that local PAF generation and release is intimately linked with the pathogenesis of glomerular injury in this form of immune disease.
