Sterile inflammation is a therapeutic target in many diseases where it represents an important initiator of disease progression. However, the detailed mechanisms underlying its evolution and biological relevance are not yet completely elucidated. Biglycan, a prototype extracellular matrix-derived damage-associated molecular pattern, mediates sterile inflammation in macrophages through Toll-like receptor (TLR) 2 and/or TLR4-dependent signaling pathways. Here we discovered that soluble biglycan is a novel high-affinity ligand for CD14, a well-known GPI-anchored co-receptor for TLRs...

Ischemia/reperfusion injury holds a key position in many pathological conditions such as acute kidney injury and in the transition to chronic stages of renal damage. We hypothesized that besides a reported disproportional activation of vasoconstrictor response, hypoxia/reoxygenation (H/R) adversely affects endothelial dilatory systems and impairs relaxation in renal arteries. Rat renal interlobar arteries were studied under isometric conditions. Hypoxia was induced by application of 95% N2 , 5% CO2 for 60 min to the bath solution, followed by a 10 min period of reoxygenation (95% O2 , 5% CO2 )...

Background Delayed graft function (DGF) is a common complication following kidney transplantation and is associated with ischemia-reperfusion injury (IRI). Lymphocytes contribute to the pathogenesis of IRI and ischemia-reperfusion related delayed graft function Materials and Methods 135 Caucasian patients received a kidney graft from deceased heart-beating organ donors. We divided patients into 2 groups- patients with the eGFR>=30 on the 21st day post-transplantation (n=36) and patients with the eGFR<30 on the 21st day post-transplantation (n=99) to assess kidney graft function...

Based on the abnormally increased expression of CD44 receptors on renal tubule epithelial cells during ischemia/reperfusion-induced acute kidney injury (AKI), we developed a hyaluronic acid-curcumin (HA-CUR) polymeric prodrug targeting to epithelial cells and then relieving oxidative stress damages. The water solubility of HA-CUR was significantly enhanced and approximately 27-fold higher than that of CUR. Cellular uptake test showed HA-CUR was preferably internalized by H2 O2 -pretreated tubular epithelial (HK-2) cells compared with free CUR benefiting from the specific binding between HA and CD44 receptors...

Rapamycin, an immunosuppressant, is widely used in patients with kidney transplant. However, the therapeutic effects of rapamycin remain controversial. Additionally, previous studies have revealed deleterious effects of rapamycin predominantly when administered for ≥24 h. Few studies, however, have focused on the short-term effects of rapamycin administered only during the initial reperfusion phase. As such, we designed this study to explore the potential effects and mechanisms of rapamycin under a specific therapeutic regimen in which rapamycin is mixed in the perfusate during the initial reperfusion phase (within 24 h)...

Acute kidney injury (AKI) represents the most frequent complication after cardiac surgery. Macrophage migration inhibitory factor (MIF) is a stress-regulating cytokine that was shown to protect the heart from myocardial ischemia-reperfusion injury, but its role in the pathogenesis of AKI remains unknown. In an observational study, serum and urinary MIF was quantified in 60 patients scheduled for elective conventional cardiac surgery with the use of cardiopulmonary bypass. Cardiac surgery triggered an increase in MIF serum concentrations, and patients with high circulating MIF (>median) 12 hours after surgery had a significantly reduced risk of developing AKI (relative risk reduction, 72...

Early and adequate restoration of endothelial and tubular renal function is a substantial step during regeneration after ischemia reperfusion (IR) injury, occurring, e.g., in kidney transplantation, renal surgery, and sepsis. While tubular epithelial cell injury has long been of central importance, recent perception includes the renal vascular endothelium. In this regard, the fibrin cleavage product fibrinopeptide Bβ15-42 mitigate IR injury by stabilizing interendothelial junctions through its affinity to VE-cadherin...

Acute kidney injury is a major risk factor for subsequent chronic renal and/or cardiovascular complications. Previous studies have shown that Notch3 was de novo expressed in the injured renal epithelium in the early phases of chronic kidney disease. Here we examined whether Notch3 is involved in the inflammatory response and the epithelial cell damage that typifies ischemic kidneys using Notch3 knockout mice and mice with short-term activated Notch3 signaling (N3ICD) in renal epithelial cells. After ischemia/reperfusion, N3ICD mice showed exacerbated infiltration of inflammatory cells and severe tubular damage compared to control mice...

As a major cause of renal failure, transient renal ischemia and reperfusion induce both acute kidney injury and late fibrosis, which are the common pathological manifestations of end-stage renal disease. Curcumin is a biologically active polyphenolic compound found in turmeric. Increasing evidence has demonstrated that curcumin has a protective action against renal fibrosis, whereas mechanisms underlying the anti-fibrosis role of curcumin remain poorly defined. Here, we found that APPL1, an important intracellular binding partner for AdipoR, was involved in the pathogenesis of acute injury or fibrosis and was significantly upregulated by curcumin in a mouse model of ischemia reperfusion-induced late kidney fibrosis...

This review summarizes the latest advances in knowledge on the effects of flavonoids on renal function in health and disease. Flavonoids have antihypertensive, antidiabetic, and antiinflammatory effects, among other therapeutic activities. Many of them also exert renoprotective actions that may be of interest in diseases such as glomerulonephritis, diabetic nephropathy, and chemically-induced kidney insufficiency. They affect several renal factors that promote diuresis and natriuresis, which may contribute to their well-known antihypertensive effect...

INTRODUCTION: Ischemia-reperfusion (IR) injury results from inflammation and oxidative stress, among other factors. Because of its anti-inflammatory and antioxidant properties, the Brazil nut (BN) might attenuate IR renal injury. OBJECTIVE: The aim of the present study was to investigate whether the intake of BN prevents or reduces IR kidney injury and inflammation, improving renal function and decreasing oxidative stress. METHODS: Male Wistar rats were distributed into six groups (N=6/group): SHAM (control), SHAM treated with 75 or 150 mg of BN, IR, and IR treated with 75 or 150 mg of BN...
