Glomerular deposition of alpha 2-macroglobulin in glomerular diseases.
BACKGROUND alpha 2-macroglobulin (alpha 2M) is a glycoprotein involved in delivery of growth factors, regulation of matrix degrading enzymes and modulation of fibrinolysis factors, all of which are considered as important pathogenic mechanisms of glomerular injury. However, the role of alpha 2M in glomerular disease has not been extensively studied. The amount, frequency and local distribution ...
متن کاملAcute Glomerular Diseases in Children
Glomerulonephritis [GN] is one of the common acquired pediatric renal disorders encountered in clinical practice. The clinical manifestations include gross or microscopic hematuria, proteinuria, and nephrotic syndrome. Renal dysfunction and hypertension may also be present in many patients. Etiopathogenesis of GN can be idiopathic in a large majority, while some may result from infections or kn...
متن کاملComplement C5b-9 induces cyclooxygenase-2 gene transcription in glomerular epithelial cells.
In rat membranous nephropathy, complement C5b-9 induces glomerular epithelial cell (GEC) injury and proteinuria, which is partially mediated by eicosanoids. Rat GEC in culture express cyclooxygenase (COX)-1 constitutively, whereas COX-2 expression is induced by C5b-9. Both isoforms contribute to complement-induced prostaglandin generation. The present study addresses mechanisms of complement-in...
متن کاملComplement C5b-9 membrane attack complex increases expression of endoplasmic reticulum stress proteins in glomerular epithelial cells.
In the passive Heymann nephritis (PHN) model of membranous nephropathy, complement C5b-9 induces glomerular epithelial cell (GEC) injury, proteinuria, and activation of cytosolic phospholipase A(2) (cPLA(2)). This study addresses the role of endoplasmic reticulum (ER) stress proteins (bip, grp94) in GEC injury. GEC that overexpress cPLA(2) (produced by transfection) and "neo" GEC (which express...
متن کاملHeparanase in glomerular diseases.
Heparanase is an endo-beta(1-4)-D-glucuronidase that degrades heparan sulfate (HS) polysaccharide side chains. The role of heparanase in metastasis, angiogenesis, and inflammation has been established. Recent data suggest a role for heparanase in several proteinuric diseases and an increased glomerular heparanase expression is associated with loss of HS in the glomerular basement membrane (GBM)...
