Autosomal dominant periodic fever syndromes are characterized by unexplained episodes of fever and severe localized inflammation. In seven affected families, we found six different missense mutations of the 55 kDa tumor necrosis factor receptor (TNFR1), five of which disrupt conserved extracellular disulfide bonds. Soluble plasma TNFR1 levels in patients(More)
We propose a quantitative theory of microscope interferometry where the specimen is illuminated by a cone of monochromatic light of solid angle 0 - 100 degree, corresponding to an illuminating numerical aperture of 0 to approximately 1.2. Computed results compare favorably with photometric measurements of fringe irradiance for a water wedge 0 - 2,000-nm(More)
The generation of an autoimmune response against islet beta-cells is central to the pathogenesis of type 1 diabetes mellitus, and this response is driven by the stimulation of autoreactive lymphocytes by components of the beta-cells themselves. Reactive oxygen species (ROS) have been implicated in the beta-cell destruction which leads to type 1 diabetes and(More)
OBJECTIVE To investigate the levels of the pro-inflammatory cytokines IL-6, TNF-alpha, IL-1beta, IL-8, IL-10 and IL-12p70 in the plasma of patients with TNF receptor-associated periodic syndrome (TRAPS) in relation to CRP levels and treatment with etanercept. METHODS Cytokine concentrations were measured in sequential plasma samples obtained from eight(More)
The normally functioning immune system is subject to intricate networks of regulatory mechanisms: it is therefore not surprising to find that autoimmune diseases present a complex pathogenic picture in which the relative contributions of various factors probably determine the precise nature and course of disease. This is particularly evident in the effector(More)
Quorum sensing signal molecules (QSSMs) from the bacterium Pseudomonas aeruginosa control bacterial population density and the expression of virulence determinants. Coincidentally, and possibly to allow this pathogen to gain a foothold in the human body, certain signal molecules also downregulate immunological responses in an apparently T-helper 1-selective(More)
An introductory clinical trial of the anti-oestrogenic agent IC146474 in late or recurrent carcinoma of the breast is described.Forty-six patients have been treated, of whom 10 have shown a good response. This is of the same order as that seen with oestrogens and androgens.The particular advantage of this drug is the low incidence of troublesome side(More)
We recently showed that human thyroid epithelial cells, which are normally negative for HLA-DR molecules, express HLA-DR in thyroid autoimmunity. Furthermore, induction of HLA-DR on normal thyroid cells can be achieved by culture with plant lectins. We have now found that recombinant human interferon-gamma (IFN-gamma) induces expression of HLA-DR molecules(More)
A link between Epstein-Barr Virus (EBV) and systemic lupus erythematosus (SLE) has been suggested. However, recent advances in molecular technology now permit more detailed analysis. Sera from SLE patients were tested for antibodies to several EBV antigens and had a significantly higher prevalence of immunoglobulin G antibodies against EBV early antigens(More)
