Background: Chronic kidney disease (CKD) ends mostly with renal fibrosis. The effect of CB2 receptor on renal fibrosis has been unclear. The aim of this study was to investigate the effect of CB2 receptor on renal fibrosis and the mechanisms behind it.
Methods: 50 adult male Sprague-Dawley rats were divided into 5 groups; normal, sham; rats had their ureters only manipulated, UUO; rats had their left ureters ligated, and JWH post; rats had their left ureters ligated and they received JWH 133 for 14 days, JWH pre+post; rats received JWH 133 for 14 days before and after UUO procedure. Serum creatinine and BUN were assessed together with tissue MDA, GSH, and catalase. Histopathological evaluation of the renal tissue by H&E and Masson’s trichrome was done. Immunohistochemical staining for TGF-β1, AQP1, Caspase-3, LC3B and p62 was performed. AQP1 and CB2 receptors genes expression was detected by quantitative RT-PCR.
Results: UUO had caused severe damage in the renal tissue with reduction of the renal function parameter accompanied by increase in the collagen deposition with increase TGF-β1 and decrease AQP1 expression.
Conclusions: The improvement of these parameters with JWH-133 suggests an anti-fibrotic role of CB2 receptor activation through reduction of oxidative stress, apoptosis, and autophagy.
