IgA-Fibronectin Aggregates in IgA Nephropathy

IgA interaction with carboxy-terminal 43-kD fragment of fibronectin in IgA nephropathy.

IgA deposition in the glomerular mesangial matrix is a prerequisite for the diagnosis of IgA nephropathy, and circulating IgA-containing complex has been implicated in this process. Since fibronectin is known to be involved in the assembly of extracellular matrix, this study was conducted to investigate whether fibronectin and its fragments are present in sera of patients and are capable of bin...

No pathogenic role of enhanced plasma IgA binding capacity to fibronectin and IgA-fibronectin aggregates in Henoch-Schönlein purpura.

IgA nephropathy.

A great interest in IgA nephropathy was demonstrated in the last few years. Unfortunately, a complete picture of this chronic disease should not yet been made. The article deals with 7 patients with IgA nephropathy treated in our Institute. The following characteristics were examined during a long period of time (1-17 years): clinical picture, course of the disease, clinical and morphologic cor...

[IgA nephropathy].

IgA nephropathy is glomerular disease first described in 1968 by Berger, named after him Morbus Berger. The disease is characterized by the presence of IgA dominant or codominant immunoglobulin deposits in glomerular mesangium which can be demonstrated by immunofluorescence. Clinical manifestations of IgA nephropathy in the majority of cases is hematuria which can be macro or microscopic, isola...

IgA Nephropathy.

IgA nephropathy (IgAN) is a leading cause of CKD and renal failure. Recent international collaborative efforts have led to important discoveries that have improved our understanding of some of the key steps involved in the immunopathogenesis of IgAN. Furthermore, establishment of multicenter networks has contributed to rigorous design and execution of clinical trials that have provided importan...
