In solid organ transplanted patients, annual influenza immunization is strongly recommended because of morbidity and mortality of influenza infections. In 2009, the rapid spread of a novel H1N1 influenza A virus led to the accelerated development of novel pandemic influenza vaccines. In Switzerland, the recipients received one dose of seasonal influenza and(More)
A 22-year-old patient whose primary kidney disease was focal segmental glomerulosclerosis (FSGS) developed severe recurrence of proteinuria (up to 57 g/24 h) immediately after a haploidentic living donor kidney transplantation despite pre-operative plasmapheresis. The immunosuppressive treatment consisted of tacrolimus, mycophenolate mofetil, basiliximab(More)
BACKGROUND Major-histocompatibility-complex (MHC) class II deficiency is an autosomal recessive primary immunodeficiency disease in which MHC class II molecules are absent. It is a genetically heterogeneous disease of gene regulation resulting from defects in several transactivating genes that regulate the expression of MHC class II genes. The mutations(More)
MHC class II deficiency is a severe primary immunodeficiency characterised by the absence of major histocompatibility complex class II (MHC-II) gene expression. It is genetically heterogeneous and can result from defects in at least four different trans-acting regulatory genes required for transcription of MHC-II genes. One of these genes has recently been(More)
By virtue of its control over major histocompatibility complex class II (MHC-II) gene expression, CIITA represents a key molecule in the regulation of adaptive immune responses. It was first identified as a factor that is defective in MHC-II deficiency, a hereditary disease characterized by the absence of MHC-II expression. CIITA is a highly regulated(More)
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)
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 use of restriction endonuclease analysis and Southern hybridization with our new CkF1,2 DNA probe, cold labeled with peroxidase, for the typing of Candida krusei isolates has been investigated. Fifty-five clinical samples isolated from forty-five patients hospitalized in eight centers, one environmental strain, and two reference strains were evaluated.(More)
The species specificity of the Candida krusei DNA fingerprinting probe CkF1,2 has been investigated. A total of 149 pathogenic and nonpathogenic fungal and bacterial DNAs were screened with CkF1,2. The probe was cold labeled with peroxidase, and its specificity was assessed by using Southern blot, dot blot, and colony blot hybridization. Its sensitivity was(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)
