Preventive effects and mechanisms of rhein on renal interstitial fibrosis in obstructive nephropathy.

Obstructive nephropathy and renal fibrosis.

Interstitial fibrosis has a major role in the progression of renal diseases. Several animal models are available for the study of renal fibrosis. The models of aminonucleoside-induced nephrotic syndrome, cyclosporin nephrotoxicity, and passive Heyman nephritis are characterized by molecular and cellular events similar to those that occur in obstructive nephropathy. Additionally, inhibition of a...

Evaluation of Therapeutic Effects of Autologous Bone Marrow Mesenchymal Stem Cells to Prevent the Progression of Chronic Nephropathy in Renal Transplant

Background Chronic allograft nephropathy(CAN)  is one of the most common causes of chronic and end stage renal disease. It  is defined with Mainly tubular atrophy and  interstitial fibrosis and no evidence of any other etiology, or functional disorder that caused at least three months after transplantation . Control of risk factors (HTN,DM,HLP, …) and limiting  usage of calcineurin inhibitors...

Blocking SIRT 1/2 inhibits renal interstitial fibroblast activation and attenuates renal interstitial fibrosis in obstructive nephropathy

Macrophage phenotype and renal fibrosis in obstructive nephropathy.

Macrophages have classically been recognized as key players that may promote renal fibrosis. However, several recent studies have suggested a beneficial anti-fibrotic role of infiltrating macrophages that acts to preserve renal architecture in the progressive renal scarring associated with obstructive nephropathy. Furthermore, recent investigations indicate a role for macrophages in both inflam...

Emerging Urinary Markers of Renal Injury in Obstructive Nephropathy

The effects of obstruction on renal function are the consequence of many factors that profoundly alter all components of glomerular function. Besides the acute effects on glomerular filtration rate and tubule function, a chronic obstruction induces tubular and interstitial injury that results from the activation of different pathways. The progression of tubulointerstitial injury leads to chroni...
