The noncollagenous domain hexamer of collagen IV from bovine glomerular basement membrane was further investigated to determine the types of collagen chain from which subunits M2*b and M3 are derived. M2*b was shown to be a shorter form, containing 9 fewer residues, of M2*a which was previously established as the noncollagenous domain of a third chain, a3, of collagen IV (Saus, J., Wieslander, ...

Anti-glomerular basement membrane disease is characterized by autoimmunity to antigenic sites on type IV collagen of the glomerular basement membrane. The majority of patients present with rapidly progressive glomerulonephritis and alveolar hemorrhage. The occurrence of antiglomerular basement membrane disease and other types of glomerulonephritis, such as membranous nephropathy, IgA nephropath...

Total 4-hydroxyproline content and volume were measured in the same sample of microdissected glomeruli obtained fro rat and human outer or inner cortex. Glomerular volume was determined by computer-assisted image analysis, and 4-hydroxyproline was measured by a highly sensitive gas-liquid chromatographic method. Results were expressed as weight of basement membrane material by comparison with t...

INTRODUCTION Anti-glomerular basement membrane disease is a rare autoimmune disorder characterized by pulmonary hemorrhage, crescentic glomerulonephritis and the presence of circulating anti-glomerular basement membrane antibodies. The simultaneous occurrence of both anti-glomerular basement membrane disease and membranous nephropathy is rare. CASE PRESENTATION A 59-year-old Hispanic man pres...

BACKGROUND We report a previously unrecognized and unreported case of a patient with anti-glomerular basement membrane glomerulonephritis following nintedanib, an orally active small molecule tyrosine kinase inhibitor. CASE PRESENTATION A 59-year-old Caucasian woman with a history of idiopathic pulmonary fibrosis presented with severe acute kidney injury (creatinine 285 umol/L) secondary to a...

OBJECTIVES The thickening of the glomerular basement membrane in rats after Vacor ingestion was examined by electron microscopy. This study was performed to elucidate which biochemical components changed in the glomerular basement membrane after Vacor-induced diabetic glomerulopathy. METHODS Immunohistochemical analyses of type IV collagen, laminin, fibronectin and chondroitin sulfate proteog...
