Classical complement pathway activation in membranoproliferative glomerulonephritis.
Levels of components of the classical and alternative complement pathways and the activity of the C3 nephritic factor (C3NeF) were measured in serum specimens from patients with type I (subendothelial deposits) and type II (intramembranous dense deposits) membranoproliferative glomerulonephritis (MPGN) and the results compared with the levels in normal subjects. Although C3 and C5 concentration...
متن کاملActivation of the alternative pathway of complement by monoclonal lambda light chains in membranoproliferative glomerulonephritis
Immunopathological evidence suggests that activation of the alternative pathway of complement (AP) is involved in membranoproliferative glomerulonephritis (MPGN) and in immunoglobulin A nephropathy. In this report we describe an AP dysfunction-associated factor that was isolated from the serum and urine of a patient with hypocomplementemic MPGN. Extensive glomerular deposits of C3, properdin, a...
متن کاملAnti-Complement Autoantibodies in Membranoproliferative Glomerulonephritis and Dense Deposit Disease
The complement system is an essential part of innate immunity by its role in protection against infections, but it is also involved in waste disposal and in modulating the adaptive immune response. Under physiological conditions complement activation is effectively regulated to restrain it to the required targets and extent, and to prevent collateral host tissue damage. An imbalance between com...
متن کاملHereditary and acquired complement dysregulation in membranoproliferative glomerulonephritis.
Membranoproliferative glomerulonephritis (MPGN) is a chronic progressive renal disease that is diagnosed on the basis of renal histological features. Several MPGN subtypes have been defined by the localization and composition of glomerular deposits (electron dense, Ig and C3). MPGN II or dense deposit disease (DDD) which is defined by the occurrence of electron dense deposits within the lamina ...
متن کاملMembranoproliferative Glomerulonephritis
Membranoproliferative glomerulonephritis (MPGN) refers to glomerular pathology in which there is thickening of the capillary wall together with mesangial expansion. In this article we firstly review the pathological features of MPGN and discuss how advances in our understanding of the association between abnormalities in the regulation of complement and MPGN have revealed limitations in the his...
