Response to 'Thyrocytes — not innocent bystanders in autoimmune disease'

2001

Giordano et al. propose that thyrocytes play a crucial role in the regulation of the autoimmune response during GD. According to them, Fas is weakly expressed in GD thyrocytes, whereas FasL is responsible for a specific deletion of infiltrating TH1 cells and maintains a TH2 phenotype in the lymphocytic infiltrate.

Primary in vivo T cell reactivity of NZB grafts in H-2 identical allogenic hosts.

1983

By means of the Simonson GVH-assay and the popliteal lymph node (PLN) assay, the T-cell reactivity of NZB mice against H-2 identical allogenic cells was investigated in vivo and compared to that of normal mice. None of the normal mice did react, but a highly significant NZB response could be demonstrated, which did not depend on differences in Mls antigens. These in vivo results extend previous findings of a T-cell hyperreactivity of NZB mice in primary in vitro reactions. They favour the possibility that the T-cell hyperreactivity might be relevant in vivo in facilitating autoimmune responses.

Risk for periodontal disease in patients with longstanding rheumatoid arthritis.

1998

Objective. To quantify periodontal disease in rheumatoid arthritis (RA) patients and controls, and to correlate the degree of destruction from periodontal disease and from RA Methods. Fifty RA patients were matched for age, sex, smoking status, and oral hygiene with 101 controls. Correlations between indices of chronic destruction in periodontal disease (gingival attachment loss) and in RA (Larsen radiographic score) were determined. Results. Patients with longstanding active RA (mean ± SD 13 ± 8 years) who were receiving treatment with disease-modifying antirheumatic drugs (n = 46), corticosteroids (n = 38), or nonsteroidal antiinflammatory drugs (n = 43) had a higher rate of gingival blee…

Thrombotic thrombocytopenic purpura (TTP) leading to pseudotumour's autoimmune pancreatitis (AIP): A case report

2012

International audience; Introduction: Autoimmune pancreatitis is an idiopathic inflammatory disease that produces pancreatic masses and ductal strictures. This benign disease can be associated with extrapancreatic manifestations including cholangitis, sialadenitis, inflammatory bowel disease or retroperitoneal fibrosis, mediastinal adenopathy, interstitial nephritis mainly due to immunoglobulin G4 (Ig G4), and occasional association with other auto-immune diseases. Observation: We report a 57-year-old woman who developed thrombotic thrombocytopenic purpura (UP) and pseudo-tumour's seronegative autoimmune pancreatitis (ATP) type 1. The patient was initially treated with pulse corticosteroids…

Search for genetic factors associated with susceptibility to multiple sclerosis.

2006

Multiple sclerosis (MS) is a cell-mediated autoimmune disease characterized by type-1 cytokine production. Environmental and individual genetic background might influence this response particularly in cytokine gene polymorphisms. We evaluated whether polymorphisms of interleukin (IL)-10, IL-12, and tumor necrosis factor (TNF)-alpha genes, which might play a role in MS pathogenesis, are associated with MS susceptibility. Genotype frequencies for all the analyzed polymorphisms were not differently distributed between cases and controls. It is reasonable to suppose that the cytokine single-nucleotide polymorphisms (SNPs) studied must be considered against a larger genetic background involving …

INFLUENCE OF ISLET TRANSPORTATION ON PANCREATIC ISLET ALLOTRANSPLANTATION IN TYPE 1 DIABETIC PATIENTS WITHIN THE SWISS-FRENCH GRAGIL NETWORK

2004

The influence of islet transportation on pancreatic islet allotransplantation in type 1 diabetic patients was evaluated within the GRAGIL network.From December 2001 to April 2003, 16 human pancreatic islet transplants were performed in 9 type 1 diabetic patients with an established kidney graft (functioning for at least 6 months) in four centers of the GRAGIL network. Islet isolation was performed in a core laboratory in Geneva, and the islet preparations were shipped by ambulance to each center for transplantation. One month after transplantation, the efficiency of the graft was assessed according to islet transportation time (ITT): ITT less than 2 hours (group 1, n=5), and ITT greater tha…

Family studies in scleroderma (systemic sclerosis) demonstrating an HLA-linked increased chromosomal breakage rate in cultured lymphocytes

1988

An increased chromosomal breakage rate (ICBR) was found in 27 of 28 patients with scleroderma (systemic sclerosis, SS) - 5 with the syndrome including calcinosis cutis, Raynaud phenomenon, esophagus hypomotility, sclerodactyly and telangiectasia (CREST), 4 incomplete CREST, 1 overlapping syndrome, 18 progressive systemic sclerosis (PSS). Not only the patients, but also about half of their first-degree relatives showed an increased chromosomal breakage rate (more than 5 breaks per 100 metaphases). This character segregated as a dominant marker in nine families of scleroderma patients. In the six informative of the nine families, the ICBR trait showed close linkage with the HLA region on chro…

Equal distribution of T-lymphocyte subpopulations in thymus and spleen cells of NZB and BALB/c mice

1984

NZB mice develop an autoimmune disease of unknown etiology. Since the detection of immunoregulatory T-cells it has been speculated that disbalances of these cells may be important in the course of the NZB disease. By utilization of monoclonal antibody defining immunoregulatory Lyt subsets and a FACS IV system we investigated whether differences in the number and/or marker densities of given subsets exist between NZB and the normal reference strain BALB/c. Newborn animals and animals up to 60 weeks of age were tested. No significant difference in the percentages nor in the marker densities of theta+, Lyt 1+, and Lyt 2+ cells was observed at any age or sex, neither in spleen nor in thymus. It…
