Increased intestinal intra-epithelial T lymphocytes in primary glomerulonephritis (2001)

Rostoker, Guy, Delchier, Jean-Charles, Chaumette, Marie-Thérèse

Background. There is increasing evidence that some organ‐specific and generalized autoimmune diseases in humans might be related to a breakdown of oral tolerance. We explored this hypothesis...

Frequent Association between Alteration of the rdxA Gene and Metronidazole Resistance in French and North African Isolates of Helicobacter pylori

Tankovic, Jacques, Lamarque, Dominique, Delchier, Jean-Charles, Soussy, Claude-James, Labigne, Agnes, Jenks, Peter J.

Mutations in the rdxA gene have been associated with the acquisition of resistance to metronidazole in Helicobacter pylori. This gene encodes an NADPH nitroreductase whose expression is necessary for...

Serum Antibody Responses to Helicobacter pylori and the cagA Marker in Patients with Mucosa-Associated Lymphoid Tissue Lymphoma

Taupin, Anne, Occhialini, Alessandra, Ruskone-Fourmestraux, Agnès, Delchier, Jean-Charles, Rambaud, Jean-Claude, Mégraud, Francis

The lymphoma of the mucosa-associated lymphoid tissue (MALT) of the stomach has been linked to Helicobacter pylori infection, but the mechanisms involved in B-cell proliferation remain elusive. In a...

Fast and Accurate Quantitative Detection of Helicobacter pylori and Identification of Clarithromycin Resistance Mutations in H. pylori Isolates from Gastric Biopsy Specimens by Real-Time PCR

Lascols, Christine, Lamarque, Dominique, Costa, Jean-Marc, Copie-Bergman, Christiane, Le Glaunec, Jeanne-Marie, Deforges, Lionel, ...

Rapid identification of patients infected with clarithromycin-resistant Helicobacter pylori without the need for culture can help to avoid useless prescriptions of clarithromycin. We developed and...

Induction of nitric oxide synthase in vivo and cell injury in rat duodenal epithelium by a water soluble extract of Helicobacter pylori

Lamarque, Dominique, Kiss, József, Tankovic, Jacques, François Flejou, Jean, Delchier, Jean-Charles, Whittle, Brendan J R

Helicobacter pylori (Hp) infection, which involves the gastric antrum and duodenal mucosa, may be involved in peptic ulceration by stimulating the local release of cytoxic or pro-inflammatory...
