Natural killer (NK) cells play a crucial role in the immune response to micro-organisms and tumours. Recent evidence suggests that NK cells also regulate the adaptive T-cell response and that it might be possible to exploit this ability to eliminate autoreactive T cells in autoimmune disease and alloreactive T cells in transplantation. Mature NK cells(More)
Risk for atypical hemolytic uremic syndrome (aHUS) recurrence after renal transplantation is low with an isolated membrane cofactor protein mutation (MCP). We report the case of a 32-year-old woman with a MCP who underwent kidney transplantation with a good evolution at 12 months. At 15 and 35 months, 2 episodes of thrombotic microangiopathy (TMA), after a(More)
Neural progenitor cells (NPC) of foetal origin or derived from human embryonic stem cells (HESC) have the potential to differentiate into mature neurons after transplantation into the central nervous system, opening the possibility of cell therapy for neurodegenerative disorders. In most cases, the transplanted NPC are genetically unrelated to the(More)
Complement receptor type 1 (CR1) (CD35; C3b/C4b receptor) is a transmembrane protein of many haematopoietic cells. Once cleaved, soluble complement receptor type 1 (sCR1) exerts opposite effects as a powerful inhibitor of complement. This study addressed both the question of whether sCR1 was found in bronchoalveolar lavage (BAL) of normals and patients with(More)
The in vitro mating ability of Candida lusitaniae (teleomorph Clavispora lusitaniae) clinical isolates has been investigated. Studying the effects of culture conditions, we showed that ammonium ion depletion in the medium is a major trigger of the sexual cycle. Moreover, a solid support is required for mating, suggesting a role for adhesion factors in(More)
Preformed anti-HLA antibodies (AHA) are known to be associated with delayed engraftment and reduced overall survival after adult hematopoietic stem cell transplantation. However, limited data is available in pediatric patients. In this study, we explored the role of AHA on clinical outcomes in 70 pediatric patients who received a single unit of HLA mismatch(More)
In a previous work, we described the possible relationship between a defect of purine-cytosine permease and the acquisition of a cross-resistance to the antifungal combination flucytosine (5FC) and fluconazole (FLC) in Candida lusitaniae (T. Noël, F. François, P. Paumard, C. Chastin, D. Brethes, and J. Villard, Antimicrob. Agents Chemother. 47:1275-1284,(More)
Great hopes have been placed on human pluripotent stem (hPS) cells for therapy. Tissues or organs derived from hPS cells could be the best solution to cure many different human diseases, especially those who do not respond to standard medication or drugs, such as neurodegenerative diseases, heart failure, or diabetes. The origin of hPS is critical and the(More)
Carnitine palmitoyltransferase II deficiency (CPT II) is an autosomal recessive disorder and the most frequent cause of hereditary myoglobinuria. We report the case of a young man who presented a severe fever-induced episode of rhabdomyolysis and myoglobinuria resulting in acute renal failure. Cultured skeletal muscle cells have been used for the(More)
