Peroxisome proliferator-activated receptor alpha (PPAR alpha), a member of the steroid/nuclear receptor superfamily, is known to perform various physiological functions. Recently, we reported that PPAR alpha in activated mesangial cells exerted anti-inflammatory effects and that the deficiency of PPAR alpha resulted in high susceptibility to glomerulonephritis. To investigate whether PPAR alpha activation improves the disease activity of MsPGN, we examined the protective effects of a PPAR alpha agonist, clofibrate, in a well-established model of human MsPGN, anti-Thy1 nephritis, for the first time. This study demonstrated that pretreatment with clofibrate (via a 0.02% or 0.1% clofibrate-containing diet) continuously activated the glomerular PPAR alpha, which outweighed the PPAR alpha deterioration associated with the nephritic process. The PPAR alpha activation appeared to suppress the NF-kappa B signaling pathway in glomeruli by the induction of I kappa B alpha, resulting in the reduction of proteinuria and the amelioration of the active inflammatory pathologic glomerular changes. These findings suggest the antinephritic potential of PPAR alpha-related medicines against MsPGN. PPAR alpha-related medicines might be useful as a treatment option for CKD., Article, PPAR Research.
