Female and male mice deficient in IL-10 production by targeted disruption of the IL-10 gene were infected with Plasmodium chabaudi chabaudi (AS) blood-stage parasites. Both male and female mutant mice exhibited more severe signs of disease than did +/+ or heterozygous control mice. Female defective mice also displayed an increased mortality; 56% of mice(More)
Inhibitor of proteasome, bortezomib (BOR), although highly active in vitro, showed unexpectedly low efficacy in vivo in patients with B-CLL when used alone. We studied the in vitro cytotoxic effects of BOR in combination with anti-CD20 (rituximab, RIT) or anti-CD52 (campath, CAM) monoclonal antibodies on B-CLL cells. Both BOR+RIT and BOR+CAM combinations(More)
The possible role of CD4- and CD8-bearing T lymphocytes in parasite clearance in vivo was investigated, using Plasmodium chabaudi in C57BL/6 mice as a model. Monoclonal antibodies specific for the CD4 and CD8 molecules were administered in vivo to deplete selectively the appropriate subset of T cells. The efficacy of depletion was ascertained by flow(More)
We undertook a search for cytokine-inducible molecules present on brain endothelium and which are involved in the control of lymphocyte adhesion. We screened 39 monoclonal antibodies (mAb) against rat brain endothelium in vitro, and identified five recognizing cytokine-inducible molecules. None of the 39 antibodies blocked lymphocyte adhesion, but one(More)
OBJECTIVE The anti-tumour in vitro activity of proteasome inhibitor bortezomib (PS-341, VELCADE) in combination with purine nucleoside analogues, cladribine (2-CdA) and fludarabine (FA) was tested in lymphocytes derived from 26 patients with B-cell chronic lymphocytic leukaemia (B-CLL). METHODS Cell viability was assessed by propidium iodide staining, and(More)
Strain variation in levels of inducible major histocompatibility complex (MHC) class II expression by rat cerebral endothelium has previously been reported. Using primary cell cultures of rat cerebral endothelium from PVG (RT1c), LEW (RT1l), PVG.LEW (RT1l) and PVG.AGUS (RT1lv?) strains it was determined that variation in levels of inducible MHC class II(More)
Cluster of differentiation 15 (CD15) monoclonal antibodies recognise cell adhesion molecules on the surface of many cells including normal astrocytes and metastatic carcinoma cells. The CD15 epitope (fucosyl-N-acetyl-lactosamine), an adhesive oligosaccharide, functions as a ligand for the selectin family of membrane receptors. These include CD62, a(More)
A HUVEC cDNA library was screened with sera from two patients who had developed transplant-associated coronary artery disease (TxCAD) following cardiac transplantation. A total of six positive clones were isolated from a primary screen of 40 000 genes. Subsequent DNA sequence analysis identified these to be lysyl tRNA synthetase, ribosomal protein L7,(More)
We report on a series of experiments which examines the factors controlling lymphocyte adhesion to brain endothelium in vitro and the factors which control cell migration across the endothelium, using a new migration assay. Although lymphocyte adhesion preceded migration across the brain endothelium, the two processes are not identical. We noted that(More)
