Rosiglitazone (10 μmol/L) mediated suppression of interleukin-6-induced BGN mRNA expression was mainly abrogated in peritoneal macrophages deficient in PPARγ. D and E: Graphs presenting the effects of rosiglitazone on interleukin-6 (10 ng/ml) induced BGN expression in peritoneal in vivo ( D) and in vitro ( E) generated PPARγ-deficient macrophages in comparison with wild-type macrophages as determined by real time RT-PCR. Preincubation of the cells with rosiglitazone (100 μmol/L) for 1 hour led to an almost total inhibition of BGN expression. Interleukin-6 stimulation for 6 hours resulted in a high expression of BGN mRNA in activated macrophages. Values represent mean ± SEM for three different experiments. B: Northern blot for BGN expression in mouse peritoneal macrophages stimulated for 6 hours with interleukin-6 (10 ng/ml) with and without preincubation with rosiglitazone (100 μmol/L) for 1 hour (one representative figure from three experiments). A: The graph presents the number of BGN + cells in the interstitium of kidney allografts, which are significantly fewer by PPARγ and RAR/RXR activation (mean ± SEM ** P < 0.01 vs. Original magnification: ×100 ( A, C, E, F, G) ×400 ( B and D).Įffects of rosiglitazone on BGN expression. Almost regular parenchyma after a combination of PPARγ and RXR ligand at low concentration ( G A–G: PAS). ![]() The micrographs present preglomerular arteries with only few mononuclear cells sticking to endothelium without significant narrowing of lumen glomeruli with slightly increased mesangial matrix and few mononuclear cells in the capillary lumen, surrounding tubulointerstitium with focal sparse mononuclear cell infiltrate the majority of tubules are differentiated. C– G: Representative micrographs of treated allografts: low dose rosiglitazone ( C and D), high dose rosiglitazone ( E), isotretinoin ( F), and low dose rosiglitazone and isotretinoin ( G). A and B: An untreated renal allograft showing a preglomerular artery with significant obliteration by subendothelial matrix increase, glomeruli with mesangial matrix increase, and segmental extensive broadening of peripheral basement membrane ( asterisk in B), surrounding tubulointerstitium with increased interstitial mononuclear cell infiltrate and matrix, surrounding collapsed atrophic tubules ( arrow), which are focally infiltrated by mononuclear cells ( arrowhead). Light microscopy of renal allografts 56 days after transplantation. In summary, PPARgamma activation was potently immunosuppressive and antifibrotic in kidney allografts, and these effects were enhanced by a RAR/RXR-agonist. The combination of PPARgamma- and RAR/RXR-agonists resulted in additive effects in the inhibition of fibrosis. In macrophages its secretion was blocked by rosiglitazone in a predominantly PPARgamma-dependent manner. PPARgamma activation diminished the number of cells expressing the proinflammatory and fibrogenic proteoglycan biglycan. In addition, the migratory and proliferative activity of these cells was significantly inhibited in vitro. Intragraft mononuclear cells and activated fibroblast numbers were reduced by 50%. The expression of transforming growth factor-beta1 was inhibited, whereas that of bone morphogenic protein-7 (BMP-7) was increased. The deposition of extracellular matrix proteins (collagen, fibronectin, decorin) was strikingly lower. ![]() 8.1 +/- 2.4 (low dose-Rosi P < 0.05) chronic tubulointerstitial damage score: 13.6 +/- 1.8 (controls) vs. In this study, in a Fischer to Lewis rat renal transplantation model, administration of the PPARgamma-agonist, rosiglitazone, independent of dose (3 or 30 mg/kgBW/day), lowered serum creatinine, albuminuria, and chronic allograft damage with a chronic vascular damage score as follows: 35.0 +/- 5.8 (controls) vs. We have reported that a retinoic acid (RAR)/RXR-agonist can potently influence the course of renal chronic allograft dysfunction. The nuclear receptor peroxisome proliferator-activated receptor (PPAR)gamma is a transcription factor known to have antidiabetogenic and immune effects, and PPARgamma forms obligate heterodimers with the retinoid X receptor (RXR). Chronic inflammation and fibrosis are the leading causes of chronic allograft failure. ![]()
