In a study published in PLoS Pathogens, researchers from the Institut Pasteur, in collaboration with the Institut Armand-Frappier (Canada), identified a novel nickel transporter in the gastric bacterial pathogen, Helicobacter pylori. This transporter is essential to allow H. pylori to survive the acidity of the stomach and thus to multiply and cause pathologies.The bacterium Helicobacter pylori...

Researchers from the Institut Pasteur and the CNRS have recently demonstrated that it is possible to destroy the cell wall of a bacterium by simply disrupting the assembly of two proteins. They focused on Helicobacter pylori, a model bacterium for this type of study. Their research has revealed the structure of a protein complex, which is vital for cell wall synthesis. And they have proved that,...

Scientists from the Institut Pasteur and the CNRS have recently identified new strategies used by Helicobacter pylori bacteria to infect cells. By specifically targeting mitochondria these bacteria, despite being extracellular, can optimize infection in the host. These findings pave the way for new strategies to combat H. pylori infection, which is associated with most cases of gastric cancer and...

The natural pre-colonization of the mouse digestive track by Helicobacter hepaticus and the modification of the intestinal microbiota appear to prevent the immune system from effectively controlling infection by Mycobacterium tuberculosis, the bacterium responsible for pulmonary tuberculosis. This discovery was made recently by scientists from Institut Pasteur, who used a mouse model to...

Gastric cancer, the third most common cause of cancer-related deaths, is often associated with a poor prognosis because it tends to be diagnosed at an advanced stage and is therefore difficult to treat. To reduce the death rate, it is essential to identify a biomarker enabling early diagnosis of this cancer. In pursuit of this goal, scientists from the Institut Pasteur, CNRS, and University of...

More than one in six cases of cancer worldwide are caused by infection. In total, some 2.2 million new cancer cases every year are believed to be the result of infection by a pathogenic agent. Eight viruses, one bacterium and three parasites have been classified as group 1 carcinogens (known to be carcinogenic to humans) by the International Agency for Research on Cancer, a division of the World...
