Glomerular basement membrane and anti-GBM antibody disease. 1981

B B Kirschbaum

The GBM is an important structure for the development of immunologic renal disease. It may serve as the primary antigen or as the site of deposition of immune complexes. The GBM is recognized as the major protein filtration barrier of the glomerulus. The composition of the GBM includes collagen, predominantly but not exclusively type IV, which is present as procollagen. Two glycoproteins, laminin and fibronectin, are either intrinsic components of the GBM or intimately associated with the membrane. Heparan sulfate, a glycosaminoglycan, is contained within the substance of the GBM and seems to comprise the primary anion of the structure. Antibodies to these individual GBM components are being recognized with increasing frequency in patients with glomerulonephritis. The recognition of these antibodies may serve to expand our definition of both immunologic and degenerative diseases of basement membrane.

UI MeSH Term Description Entries
D007105 Immune Complex Diseases Group of diseases mediated by the deposition of large soluble complexes of antigen and antibody with resultant damage to tissue. Besides SERUM SICKNESS and the ARTHUS REACTION, evidence supports a pathogenic role for immune complexes in many other IMMUNE SYSTEM DISEASES including GLOMERULONEPHRITIS, systemic lupus erythematosus (LUPUS ERYTHEMATOSUS, SYSTEMIC) and POLYARTERITIS NODOSA. Hypersensitivity, Type III,Type III Hypersensitivity,Disease, Immune Complex,Diseases, Immune Complex,Hypersensitivities, Type III,Immune Complex Disease,Type III Hypersensitivities
D007678 Kidney Glomerulus A cluster of convoluted capillaries beginning at each nephric tubule in the kidney and held together by connective tissue. Glomerulus, Kidney
D007797 Laminin Large, noncollagenous glycoprotein with antigenic properties. It is localized in the basement membrane lamina lucida and functions to bind epithelial cells to the basement membrane. Evidence suggests that the protein plays a role in tumor invasion. Merosin,Glycoprotein GP-2,Laminin M,Laminin M Chain,Chain, Laminin M,Glycoprotein GP 2,M Chain, Laminin
D003094 Collagen A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of SKIN; CONNECTIVE TISSUE; and the organic substance of bones (BONE AND BONES) and teeth (TOOTH). Avicon,Avitene,Collagen Felt,Collagen Fleece,Collagenfleece,Collastat,Dermodress,Microfibril Collagen Hemostat,Pangen,Zyderm,alpha-Collagen,Collagen Hemostat, Microfibril,alpha Collagen
D005353 Fibronectins Glycoproteins found on the surfaces of cells, particularly in fibrillar structures. The proteins are lost or reduced when these cells undergo viral or chemical transformation. They are highly susceptible to proteolysis and are substrates for activated blood coagulation factor VIII. The forms present in plasma are called cold-insoluble globulins.

D005921 Glomerulonephritis Inflammation of the renal glomeruli (KIDNEY GLOMERULUS) that can be classified by the type of glomerular injuries including antibody deposition, complement activation, cellular proliferation, and glomerulosclerosis. These structural and functional abnormalities usually lead to HEMATURIA; PROTEINURIA; HYPERTENSION; and RENAL INSUFFICIENCY. Bright Disease,Kidney Scarring,Glomerulonephritides,Scarring, Kidney

D006497 Heparitin Sulfate A heteropolysaccharide that is similar in structure to HEPARIN. It accumulates in individuals with MUCOPOLYSACCHARIDOSIS. Heparan Sulfate,Sulfate, Heparan,Sulfate, Heparitin
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000906 Antibodies Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).
