Renin-angiotensin system (RAS) inhibitors are effective in reducing renal disease progression in early diabetic nephropathy, but they provide imperfect protection at a later stage. Due to the pivotal role of transforming growth factor-beta (TGF-beta) in the pathogenesis of diabetic kidney disease, this study tested the effect of simultaneously interrupting(More)
This study examined psychopathology, family functioning, and cognitive style in 121 African-American adolescents who attempted suicide. Group means suggested that these youths, when taken together, were not reporting significant psychological distress. However, after classifying the youths into three groups by level of depressive symptoms interesting(More)
In mice with cisplatin-induced acute kidney injury, administration of bone marrow-derived mesenchymal stem cells (MSC) restores renal tubular structure and improves renal function, but the underlying mechanism is unclear. Here, we examined the process of kidney cell repair in co-culture experiments with MSC and cisplatin-injured proximal tubular epithelial(More)
This study has examined the effect of the cytokine interleukin 1 (IL-1) on metastasis formation by the human melanoma A375M in nude mice. We have found that human recombinant IL-1 beta (a single injection greater than 0.01 micrograms per mouse i.v. given before tumor cells) induced an augmentation of experimental lung metastases from the A375M tumor cells(More)
Members of the TLR/IL-1R superfamily mediate ischemia/reperfusion injury and initiate immune response in transplanted organs. In this study, we tested the hypothesis that Toll-IL-1R8 (TIR8), a negative regulator of TLR/IL-1R highly expressed in the kidney, modulates immune cell activation underlying kidney rejection. In a mouse model of fully mismatched(More)
Treatments for idiopathic membranous nephropathy, a common cause of nephrotic syndrome, can be very toxic. In view of the pathogenic potential of B cells in this disease, we studied the effects of four weekly infusions of rituximab (375 mg/m(2)-- the monoclonal antibody to B-cell antigen CD20--in eight patients who had idiopathic membranous nephropathy with(More)
The current therapy for chronic proteinuric nephropathies is angiotensin-converting enzyme inhibitors (ACEi), which slow, but may not halt, the progression of disease, and which may be not effective to the same degree in all patients. In accelerated passive Heymann nephritis (PHN), this study assessed the effect of combining ACEi with angiotensin II(More)
Cell therapy with Multipotent Mesenchymal Stromal Cells (MSC) holds enormous promise for the treatment of a large number of degenerative and immune/inflammatory diseases. Their multilineage differentiation potential, immunoprivilege and capacity of promoting recovery of damaged tissues coupled with anti-inflammatory and immunosuppressive properties are the(More)
Chronic renal diseases progress to organ insufficiency, which may require replacement therapy within one to three decades even independently of the type of initial insults. In the majority of cases, the degrees of proteinuria and interstitial leukocyte infiltration and scarring are strictly correlated with the rate of disease progression. This study tests(More)
In proteinuric glomerulopathies, the excess traffic of proteins into the renal tubule is a candidate trigger of interstitial inflammatory and immune events leading to progressive injury, and a key target for the renoprotective action of antiproteinuric drugs. Among proteins trafficked to the proximal tubule, the third component of complement (C3) can be(More)
