Both partial inactivation as well as activation of NF-κB signaling lead to hypertension and chronic kidney disease

Popis výsledku v původním jazyce

BACKGROUND AND HYPOTHESIS: Activation of NF-κB-signalling is key in the pathogenesis of chronic kidney diseases (CKD). However, a certain level of NF-κB activity is necessary to enable tissue repair. METHODS: To investigate the relationship between activated and inactivated NF-κB signaling on the pathogenesis of CKD using mouse models of NF-κB partial inactivation (mutating cysteine at position 59 of the sixth exon on the NF-κB gene into alanine) and activation (mutating cysteine at position 59 of the sixth exon on the NF-κB gene into serine). RESULTS: The density of CD3, CD8, CD68 positive cells, as well as the expression of IL-6, TRAF-1, and NAF-1 in the kidney tissues of NF-κBC59A mice were reduced, whereas an opposing pattern was observed in the NF-κBC59S mice. Blood pressure, kidney fibrosis (analyzed by PAS-, Masson trichrome-, and Sirius-Red-staining as well as α-SMA immunofluorescence), serum creatinine and urinary albumin-to-creatinine-ratio are markedly increased in NF-κB activated and inactivated mice compared to controls. Transmission electron microscopy indicated that the glomerular basement membrane was thicker in both NF-κBC59A and NF-κBC59S mice compared to wild-type mice. CONCLUSIONS: Using mice models with partially activated and inactivated NF-κB pathways suggests that there is an apparently U-shaped relationship between blood pressure, kidney function as well as morphology and the activation of the NF-κB pathway. A certain optimal activity of the NF-κB pathway seems to be important to maintain optimal kidney function and morphology.
