This paper reports on the total fatty acid composition of a marine bacterium representative of the genus Flexibacter. Flexibacter polymorphus is unusual in containing a high proportion of the polunsaturated acid C20:5ω3 whilst the level of branched fatty acids is low. These facts suggest that the membrane flexibility necessary for its gliding motility is a(More)
The mechanisms by which anti-DNA MoAbs derived from MRL-lpr/lpr mice, bind to human umbilical vein endothelial cells (HUVEC) and glomerular mesangial cells were studied using a cellular ELISA. DNAse-treatment of either the MoAb or HUVEC followed by reconstitution with DNA and/or histones was performed to determine whether DNA and histones mediated such(More)
The interaction of circulating autoantibodies with the endothelium may be an important mechanism in the pathogenesis of systemic vasculitis. In a prospective study, we looked for circulating antiendothelial cell autoantibodies (AECA) and anti-neutrophil cytoplasm autoantibodies (ANCA) in 80 patients with suspected systemic vasculitis. AECA were measured(More)
A 28-year-old woman underwent peripheral-blood stem cell transplantation from her HLA-identical sister for cytogenetic progression of Fanconi anemia. She had received a living-related renal allograft from her father 2 years previously. Nine days after peripheral-blood stem cell transplantation, she developed acute renal failure secondary to acute rejection.(More)
Ten patients with systemic vasculitis, all positive for anti-neutrophil cytoplasm antibody (ANCA), were followed for a mean of 36 weeks to determine the prevalence of anti-endothelial cell antibodies (AECAs) and the relationship between AECAs, ANCAs, and disease activity. Anti-endothelial cell antibodies were detected in eight (80%) patients at some time(More)
Systemic lupus erythematosus is characterized by the production of a broad spectrum of autoantibodies. Autoantibodies directed against endothelial cells (AECA) have been particularly well documented. We investigated associations between such antibodies, double-stranded DNA (dsDNAb), phospholipid (cardiolipin, ACA), and indices of activity and chronicity(More)
