OBJECTIVES: I. Determine whether allelic differences associated with the fourth component of complement, type-1 complement receptor expressed on erythrocytes, and Fc receptor FcgRIII contribute to the pathogenesis of IgA glomerulonephritis (IgA-N).
II. Compare genetic anomalies of these key components in immune complex processing and clearance between juvenile vs adult onset IgA-N vs normal controls.
Participants undergo qualitative genetic analysis of complement-related proteins. Studies include: genomic re-arrangement of 4-gene unit, C4 DNA sequence and RNA expression, type-1 complement receptor DNA sequence, Fc-gamma receptor IIIA isoform analysis, classical and alternative complement activation pathway assays, plasma C4 and C4d protein levels, and immunoglobulin patterns in glomerular deposits.

we hypothesize that PTX might be effective in lowering proteinuria by modulating renal MCP-1 production in human glomerulonephritis.
This study evaluates prospectively the effects of an anti-angiotensin II regimen on renal outcome in patients with mesangioproliferative glomerulonephritis followed-up for 10 years.
Glomerulonephritis (GN) is one of the most important causes of kidney failure in Canada. These comprise a group of "rare" diseases (
Glomerulonephritis (GN) is the leading cause of end-stage renal disease in 30% to 50% of patients who receive a renal transplant. The exact prevalence of either recurrent or de novo GN is ...
Acute post streptococcal glomerulonephritis is an immunologic response of the kidney to infection, characterized by the sudden appearance of edema, hematuria, proteinuria and hypertension ...
Information on long-term renal outcome of pediatric glomerulonephritis associated with crescent formation is limited. A single center retrospective study was conducted to assess long-term renal surviv...
Rapidly progressive glomerulonephritis caused by overlap syndrome of IgG4-related tubulointerstitial nephritis and myeloperoxidase-antineutrophil cytoplasmic antibody-associated necrotising glomerulonephritis.
Membranoproliferative glomerulonephritis (MPGN) has been reclassified from an electron microscopy to an immunofluorescence (IF) based semi quantitative classification with immunoperoxidase (IP) techni...
Immunopathologic features predict renal function at baseline and follow-up in antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (GN). The interstitial infiltrate consists predom...
Renal involvement in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis contributes to significant morbidity and mortality in patients. In chronic inflammation, B cells are recruited to...
Glomerulonephritis associated with autoimmune disease SYSTEMIC LUPUS ERYTHEMATOSUS. Lupus nephritis is histologically classified into 6 classes: class I - normal glomeruli, class II - pure mesangial alterations, class III - focal segmental glomerulonephritis, class IV - diffuse glomerulonephritis, class V - diffuse membranous glomerulonephritis, and class VI - advanced sclerosing glomerulonephritis (The World Health Organization classification 1982).
A chronic form of glomerulonephritis characterized by deposits of predominantly IMMUNOGLOBULIN A in the mesangial area (GLOMERULAR MESANGIUM). Deposits of COMPLEMENT C3 and IMMUNOGLOBULIN G are also often found. Clinical features may progress from asymptomatic HEMATURIA to END-STAGE KIDNEY DISEASE.
A type of glomerulonephritis that is characterized by the accumulation of immune deposits (COMPLEMENT MEMBRANE ATTACK COMPLEX) on the outer aspect of the GLOMERULAR BASEMENT MEMBRANE. It progresses from subepithelial dense deposits, to basement membrane reaction and eventual thickening of the basement membrane.
Chronic glomerulonephritis characterized histologically by proliferation of MESANGIAL CELLS, increase in the MESANGIAL EXTRACELLULAR MATRIX, and a thickening of the glomerular capillary walls. This may appear as a primary disorder or secondary to other diseases including infections and autoimmune disease SYSTEMIC LUPUS ERYTHEMATOSUS. Various subtypes are classified by their abnormal ultrastructures and immune deposits. Hypocomplementemia is a characteristic feature of all types of MPGN.
A complex of antigenic proteins obtained from the brush border of kidney tubules. It contains two principal components LDL-RECEPTOR RELATED PROTEIN 2 and LDL-RECEPTOR RELATED PROTEIN-ASSOCIATED PROTEIN. The name of this complex is derived from researcher, Dr. Walter Heymann, who developed an experimental model of membranous glomerulonephritis (GLOMERULONEPHRITIS) by injecting this antigenic complex into rats to induce an autoimmune response.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
