Fate alteration of bone marrow-derived macrophages ameliorates kidney fibrosis in murine model of unilateral ureteral obstruction.
Renal fibrosis is a key pathological feature and final common pathway leading to end-stage kidney failure in many chronic kidney diseases. Myofibroblast is the master player in renal fibrosis. However, myofibroblasts are heterogeneous. Recent studies show that bone marrow-derived macrophages transform into myofibroblasts by transforming growth factor (TGF)-β-induced macrophage-myofibroblast transition (MMT) in renal fibrosis. ⋯ Our results demonstrate that diversion of β-catenin from TCF to Foxo1-mediated transcription not only inhibits the β-catenin/TCF-mediated fibrotic effect of TGF-β, but also enhances its anti-inflammatory action, allowing therapeutic use of TGF-β to reduce both inflammation and fibrosis at least partially by changing the fate of bone marrow-derived macrophages.

Sodium bicarbonate catheter lock solution reduces hemodialysis catheter loss due to catheter-related thrombosis and blood stream infection: an open-label clinical trial.
There is no ideal lock solution that prevents hemodialysis (HD) catheter loss due to catheter-related thrombosis (CRT) and catheter-related bloodstream infection (CRBSI). Catheter loss is associated with increased hospitalization and high inpatient costs. Sodium bicarbonate (NaHCO3) demonstrates anti-infective and anticoagulation properties with a good safety profile, making it an ideal lock solution development target.The objective of this study was to determine the safety and efficacy of using sodium bicarbonate catheter lock solution (SBCLS) as a means of preventing HD catheter loss due to CRT and CRBSI. ⋯ The novel approach of using SBCLS was found to be safe and was statistically superior to normal saline in preventing HD catheter loss due to CRT and CRBSI. NaHCO3 solution is inexpensive, readily available in various settings and holds the potential to decrease hospitalization, length of stay and dialysis-related costs.
