Forty seven renal allografts performed over a period of 12 years in 43 recipients with chronic renal failure due to biopsy-proved focal glomerulosclerosis (FGS, 5.34% from 888 cadaveric renal transplantations) were reviewed. Recurrence of the disease was suspected in 14 grafts (29.8%) on the basis of immediate proteinuria, but recurrence of FGS lesions was(More)
BACKGROUND At 8 weeks, Buffalo/Mna rats spontaneously develop a nephrotic syndrome associated with focal segmental glomerulosclerosis (FSGS). We have previously demonstrated that this glomerulopathy recurs after renal transplantation, thus supporting the relevance of this rat model to human idiopathic nephrotic syndrome [1]. In this study, we describe renal(More)
Buffalo/Mna rats spontaneously develop FSGS and nephrotic syndrome as a result of an immune disorder. Similar to some humans with FSGS, the disease recurs after renal transplantation, suggesting the involvement of a circulating factor. Here, we tested the effect of several immunosuppressive treatments on these rats. Although corticosteroids, cyclosporin A,(More)
Buffalo/Mna rats spontaneously develop a focal segmental glomerulosclerosis with a histological pattern similar to the human disease. In this study, we investigated the potential of recurrence of the disease by transplantation of normal kidneys into Buffalo/Mna recipients. Kidneys from healthy LEW.1W rats were grafted into proteinuric 6-month-old(More)
The authors report two new cases of functional parathyroid carcinoma, the course of which varied between 5 and 7 years. The main fact was their familial character, as the disease affected two siblings. No similar case was found in the world literature. These two cases were characterised by symptoms in the bones or pancreatic symptoms which dominated the(More)
Several immune responses are either limited to or concentrated in a given organ. Cytokines produced during ongoing immune responses have organ-localized effects that can be only partially mimicked upon their systemic delivery. Recombinant adenoviruses are efficient vectors to induce transient organ-localized cytokine expression. This allows in vivo analysis(More)
BACKGROUND Nitric oxide plays an important role in the kidney through effects on both renal hemodynamics and tubular functions. Tubular epithelial cells are thus a target for nitric oxide. However, as to whether tubular epithelial cells endogeneously produce nitric oxide under physiologic conditions in human kidney is currently unknown. The aim of the(More)
In normal human kidney, NOS1 and soluble guanylate cyclase (sGC) are expressed in tubular epithelial cells, suggesting a physiological autocrine NO signalling pathway. Therefore, we investigated both NOS1 and sGC expressions in benign and malignant renal tumours. In addition, we examined the pattern of protein tyrosine nitration in normal and tumour tissue.(More)
T-cells and their cytokines are thought to play a major role in the genesis of cellular infiltration and rejection in human kidney allografts. Production of Th1 (IFN-gamma) and Th2-type (IL-4 and IL-5) cytokines was assessed in a large series of T-cell clones, derived from core biopsies of kidney grafts in 10 patients with acute interstitial grade I/II(More)
