A pilot study of anti-nephrin antibodies in podocytopaties among adults.

Aim: Minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS) are podocytopathies characterized by damage to the glomerular filtration barrier, leading to proteinuria and nephrotic syndrome. The production of anti-podocyte antibodies has been proposed as potential circulating factors contributing to the development of these conditions. The aim of the study is to evaluate the levels of anti-nephrin antibodies in patients with podocytopathies and healthy subjects.

Preliminary study of anti-CD40 and ubiquitin proteasome antibodies in primary podocytopaties.

Background: Minimal change disease and focal segmental glomerulosclerosis are primary podocytopathies that are clinically presented in adults presenting with severe nephrotic syndrome. The pathogenesis of these diseases is not clear and many questions remain to be answered. A new concept about the role of changes in the antigenic determinant of podocytes and the production of anti-podocyte antibodies that cause podocyte damage is being developed.

A cross-sectional study of antibodies to ubiquitin proteasome system in different glomerulopathies.

Background: Recently, evidence has emerged that the ubiquitin system, which is involved in extracellular protein degradation, is most susceptible to damage in podocytes in cases of podocytopathies. We studied anti-ubiquitin carboxyl-terminal hydrolase L1 (UCHL1) antibodies in glomerulopathies with proteinuria.

Materials And Methods: 71 patients with glomerulopathy and 11 healthy subjects were included in our study.

Serum levels of plasminogen activator urokinase receptor and cardiotrophin-like cytokine factor 1 in patients with nephrotic syndrome.

Unlabelled: The pathogenesis of primary focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD) remains unknown to date. Some circulating permeability factors are being discussed. This work assessed molecule candidates for permeability in serum samples of patients with nephrotic syndrome (NS).

On normalizing of urinary KIM-1 level to urine creatinine in patients with renal cell cancer.

KIM-1 (kidney injury molecule 1), a marker of acute kidney injury, is produced by epithelial cells of renal proximal tubules. Elevated KIM-1 levels in urine and plasma are associated with renal cell carcinoma (RCC). The aim of this study was to compare the significance of non-normalized uKIM-1 values and those normalized to urine creatinine, as urinary biomarkers in RCC.

Dimebon slows progression of proteinopathy in γ-synuclein transgenic mice.

Intermediates and final products of protein aggregation play crucial role in the development of degenerative changes in a number of neurological diseases. Pathological protein aggregation is currently regarded as one of the most promising therapeutic targets for treatment of these diseases. Transgenic mouse models of proteinopathies are an effective tool for screening and validation of compounds, which can selectively affect metabolism of aggregate-prone proteins.
