Macrophages directly mediate diabetic renal injury.
Monocyte/macrophage recruitment correlates strongly with the progression of renal impairment in diabetic nephropathy (DN), yet their direct role is not clear. We hypothesized that macrophages contribute to direct podocyte injury and/or an abnormal podocyte niche leading to DN. Experiments were conducted in CD11b-DTR mice treated with diphtheria toxin (DT) to deplete macrophages after streptozot...
متن کاملIron uptake promotes hyperoxic injury to alveolar macrophages.
Iron uptake by cells may increase the intracellular pool of prooxidant iron prior to storage of iron within ferritin. Because hyperoxia is toxic to alveolar macrophages (AM) via mechanisms involving oxidant stress, we hypothesized that iron uptake by AM might promote hyperoxia-induced injury. To assess this hypothesis, we cultured AM recovered from healthy volunteers under conditions of normoxi...
متن کاملRenal IL-18 Production Is Macrophage Independent During Obstructive Injury
BACKGROUND Interleukin 18 (IL-18) is a pro-inflammatory cytokine that mediates fibrotic renal injury during obstruction. Macrophages are a well-known source of IL-18; however, renal tubular epithelial cells are also a potential source of this cytokine. We hypothesized that IL-18 is predominantly a renal tubular cell product and is produced during renal obstruction independent of macrophage infi...
متن کاملObstructive renal injury: from fluid mechanics to molecular cell biology
Urinary tract obstruction is a frequent cause of renal impairment. The physiopathology of obstructive nephropathy has long been viewed as a mere mechanical problem. However, recent advances in cell and systems biology have disclosed a complex physiopathology involving a high number of molecular mediators of injury that lead to cellular processes of apoptotic cell death, cell injury leading to i...
متن کاملEmerging Urinary Markers of Renal Injury in Obstructive Nephropathy
The effects of obstruction on renal function are the consequence of many factors that profoundly alter all components of glomerular function. Besides the acute effects on glomerular filtration rate and tubule function, a chronic obstruction induces tubular and interstitial injury that results from the activation of different pathways. The progression of tubulointerstitial injury leads to chroni...
