When infection strikes, what if our immune system was not alone in the fight? What if its major ally was in fact the brain? Researchers from Inserm, CNRS and Aix-Marseille University (AMU) have observed mechanisms of cooperation between the nervous system and the immune system in the response to pathogenic aggressions. This research, published in Nature Immunology, reveals the role of the brain in regulating the inflammatory reaction induced...
In a context of increasing vaccine hesitancy, researchers from Inserm and pediatricians from the Nantes and Grand-Ouest university hospitals together with the Paris public hospitals (AP-HP) sound the alarm concerning the consequences of severe bacterial infections in children. In a study published in Paediatric and Perinatal Epidemiology, the researchers showed, over a period of 5 years, that 25 % of deaths and 25 % of serious after-effects occurring in children with a...
A study conducted by a group of researchers from Paris Diderot University, INSERM and the Institut Pasteur reveals the existence of a genetic factor influencing the function of the human thymus. The results of the study, part of the Laboratories of Excellence project Milieu Intérieur coordinated by the Institut Pasteur, are published in the journal Science Translational Medicine on September 5, 2018.
Since July, a new outbreak of Ebola virus disease was identified in the Democratic Republic of the Congo – the second since May. In an attempt to halt the outbreak, a new vaccination campaign has begun in the affected region of North Kivu. It is against this background that researchers from the consortium PREVAC (Partnership for Research on Ebola VACcination) take stock of advances in Ebola vaccine research...
An estimated 75 000 people in France are unaware they are infected by hepatitis C virus. An ANRS-funded study by Sylvie Deuffic-Burban, a research associate at IAME (Infection, Antimicrobials, Modeling, Evolution) (Inserm - Université Paris Diderot - Université Paris 13), and her team shows that a universal screening strategy applied to hepatitis C is cost-effective and improves life expectancy in those infected, compared with targeted screening. These modeling results will...
Des chercheurs du CNRS, de l’Inserm et de l’Université Grenoble Alpes viennent de décrypter les mécanismes déployés par le parasite Toxoplasma gondii pour pénétrer dans les cellules de ses hôtes. À l’aide d’une imagerie quantitative à haute vitesse et haute résolution, ils ont identifié un mouvement singulier du parasite qui lui permet de fermer derrière lui la porte qu’il a créée pour rentrer dans la cellule-hôte et s’y nicher....
Numerous compounds are involved in the complex interactions that exist between our body and its microbiota. One of these is the essential amino acid, tryptophan. On June 13, 2018, in the journal Cell Host and Microbe, a team from Inra, AP-HP, Sorbonne Université and Inserm gathered the most recent advances concerning the central role of tryptophan in the dialog with our gut microbiota. Data which opens opportunities for research...
Three new members have been isolated and added to the Pandoravirus family by researchers at the Structural and Genomic Information Laboratory (CNRS/Aix‐Marseille Université), working with partners at the Large Scale Biology Laboratory (CEA/Inserm/Université Grenoble‐Alpes) and at CEA-Genoscope. This strange family of viruses, with their giant genomes and many genes with no known equivalents, surprised the scientists when they were discovered a few years ago. In the 11 June 2018...
A team of researchers from CNRS, INSERM and Aix-Marseille Université (AMU) at the Centre of immunology (Marseille-Luminy (CIML), together with the Singapore Immunology Network (SIgN)1, has proven that not all of the immune system's important mast cells are produced in bone marrow, as was previously thought. Scientists found embryonic mast cells in mice with functions that are likely to be different than the mast cells found in adults. The...
While Bacillus cereus is well known as a source of food infections, researchers from INRA and ANSES, working with doctors at nine French hospitals[1] including those in the Paris Public Hospital System (AP-HP), have demonstrated for the first time that this bacterium is also responsible for inter- and intra-hospital nosocomial contamination. This study, conducted in 39 patients between 2008 and 2012, also found strains of B. cereus in the hospital environment capable of causing...
