[The key role of tubulointerstitium remodeling in progression of chronic renal diseases].
Tubulointerstitial fibrosis (TIF) is thought now to be a key factor in progression of renal failure in chronic nephropathies. A similar pattern of changes in glomerulonephritis and amyloidosis suggests common mechanisms operating in progression of renal failure in these nephropathies. Of importance in the process of interstitial inflammation is activation of the nuclear factor of transcription (NFkB) in tubular cells due to components of proteinuria and their secretion of some proinflammatory mediators, first of all chemokines with formation of inflammatory infiltrate and accumulation of interstitial myofibroblasts--the main source of extracellular matrix (ECM) components. Our findings are of interest in the light of current ideas that among ECM components the number of fibronectin deposites most of all reflects the severity of structural renal tissue damage including TIF and correlates with severity of renal failure.
