Renal progenitor cells contribute to hyperplastic lesions of podocytopathies and crescentic glomerulonephritis.
Glomerular injury can involve excessive proliferation of glomerular epithelial cells, resulting in crescent formation and obliteration of Bowman's space. The origin of these hyperplastic epithelial cells in different glomerular disorders is controversial. Renal progenitors localized to the inner surface of Bowman's capsule can regenerate podocytes, but whether dysregulated proliferation of thes...
متن کاملContributions of intrinsic renal cells to crescentic glomerulonephritis.
The pro-inflammatory contributions of leukocytes, particularly macrophages and T cells, to the immunopathogenesis of proliferative forms of glomerulonephritis (GN) have been clearly established by various techniques, including in vivo depletion studies in experimental models. The evidence for an active pro-inflammatory role for intrinsic renal cells in GN has relied on studies demonstrating the...
متن کاملT cells in crescentic glomerulonephritis.
Crescent formation in glomerulonephritis (GN) is a manifestation of severe glomerular injury that usually results in a poor clinical outcome. In humans, crescentic GN is frequently associated with evidence of either systemic or organ-specific autoimmunity. T cells play a major role in initiation of adaptive immune responses that lead to crescentic injury. In experimental models of crescentic GN...
متن کاملRheumatoid arthritis associated with renal amyloidosis and crescentic glomerulonephritis.
A 43-year-old woman with rheumatoid arthritis (RA), renal amyloidosis and crescentic glomerulonephritis had severe abdominal pain, melena and progressive renal failure. Autopsy findings revealed vasculitis of small and middle size of vessels and there was a deposition of amyloid in the small intestines. Although there were no findings of vasculitis in the kidney, amyloid deposition was noticed ...
متن کاملPattern recognition and renal defence in crescentic glomerulonephritis.
Chavele et al. studied the role of the mannose receptor (MR) in crescentic nephritis. The accelerated nephrotoxic model of glomerulonephritis was induced on both wild-type (WT) and MR-deficient mice. The mice lacking the MR showed a markedly altered phenotype. They were largely protected against the development of glomerulonephritis with less affected glomeruli, less proteinuria and much better...
