Gilles Bloch has been appointed Chairman and Chief Executive Officer of the French National Institute of Health and Medical Research (Inserm) by the Council of Ministers.
As tumors develop, they evolve genetically. How does the immune system act when faced with tumor cells? How does it exert pressure on the genetic diversity of cancer cells? Scientists from the Institut Pasteur and Inserm used in vivo video techniques and cell-specific staining to visualize the action of immune cells in response to the proliferation of cancer cells. The findings have been published in the journal Science Immunology...
Asymmetry plays a major role in biology at every scale: think of DNA spirals, the fact that the human heart is positioned on the left, our preference to use our left or right hand … A team from the Institute of biology Valrose (CNRS/Inserm/Université Côte d’Azur), in collaboration with colleagues from the University of Pennsylvania, has shown how a single protein induces a spiral motion in another molecule. Through...
The findings, published in the journal Gastroenterology in November 2018, show that if the liver cancer risk is greatly reduced after viral eradication in these patients, it still persists and justified to keep patients with viral cirrhosis C cured in screening programs. This study also confirms the benefits of virologic cure the risk of hepatic carcinogenesis regardless of the type of antiviral treatment.
Researchers from Inserm, CNRS, Paris-Sud University, Gustave Roussy, and Institut Curie have identified a new agent in regulating PD-L1 gene expression: the eIF4F complex, which plays a role in controlling protein synthesis.
As part of the InFoR-Autism* scientific program, supported by Institut Roche, an MRI neuroimaging study investigated the links between local anatomical connectivity and social cognition in individuals with autism spectrum disorder (ASD).
A research team from CNRS, Université PSL, the Collège de France and Inserm has just lifted part of the veil surrounding brain activity during sleep. Though we know that some neurons are reactivated then to consolidate our memories, we did not know how these cells could “remember” which order to turn on in. The researchers have discovered that reactivating neurons during sleep relies on activation that occurs during...
Researchers from CIRI - International Center for Research in Infectious Diseases in Lyon (Inserm, CNRS, ENS Lyon and Claude Bernard Lyon 1 University), supported by the ANRS, are demonstrating the link between activation of a bile acid receptor found in liver cells and the reduction in hepatitis B virus replication in mice infected with the virus.
Researchers from Inserm, Université de Bordeaux and Sorbonne Université have published a study showing that, out of a population of older adults, nearly 40 % have a poorly-corrected vision problem (such as nearsightedness, farsightedness and astigmatism) which could be improved by wearing more suitable glasses. These findings have been published in JAMA Ophthalmology.
A group of over fifteen scientists, led by Samuel Vergès, an Inserm researcher from the “Hypoxia and Cardiovascular and Respiratory Physiopathologies” group (Inserm/Université Grenoble Alpes), is taking part in a scientific expedition to investigate the effect of low oxygen levels on health. In early 2019 they will spend 6 weeks in the world’s highest settlement, situated in Peru at an altitude of 5,300 m, studying how its inhabitants have...
