Découverte d’une réaction immunitaire cruciale lors de la diversification alimentaire pour prévenir l’apparition des maladies inflammatoires

(Français) Les microbes colonisent l’ensemble des surfaces de notre corps et participent au bon équilibre de notre système immunitaire. Chez les nouveau-nés, le microbiote intestinal est d’abord formaté par les composants du lait maternel. Lors de la diversification alimentaire, il se développe et de nombreuses bactéries prolifèrent. Des chercheurs de l’Institut Pasteur et de l’Inserm montrent chez la souris qu’une réponse immunitaire importante se produit lors de l’introduction de nourriture solide et du développement du microbiote. Mais surtout, ils ont montré que cette réaction immunitaire était essentielle car elle participe à l’éducation du système immunitaire, et permet, à l’âge adulte, une faible susceptibilité aux maladies inflammatoires (allergies, colites, maladies auto-immunes, cancer). Ces résultats ont été publiés dans la revue Immunity, le 19 mars 2019.

Go for a Run or Eat Chocolate: A Choice Dictated by the Cannabinoid Receptors

Physical inactivity is a common factor in lifestyle diseases – and one that is often linked to the excessive consumption of fatty and/or sugary foods. The opposite scenario of excessive physical activity at the expense of caloric intake can also be harmful, as cases of anorexia nervosa illustrate. These data therefore point to the crucial need to research the neurobiological processes that control the respective motivations for exercise and food intake. A study by Inserm and CNRS researchers published on March 7, 2019 in JCI Insight reveals that the cannabinoid type 1 (CB1) receptors play an essential role in the choice between running and eating chocolatey food.

Metastatic Lung Cancer: A Targeted Therapy to Improve Treatment Efficacy

When faced with the most aggressive forms of lung cancer, how can the efficacy of chemotherapy be increased? Teams from Inserm, Université Paris Descartes and the Paris public hospitals system AP-HP have maybe hit on a solution. They have developed a targeted therapy which aims to improve the response to platinum salts – the standard chemotherapy used in lung cancer – by neutralizing the activity of a receptor that contributes to its aggressiveness. This research, published in Cancer Letters, shows that in mice this therapy restores the response to chemotherapy and reduces the risk of metastasis by one half to two thirds.

Alzheimer’s disease: five new genetic markers identified

Knowledge of the genetic component of Alzheimer’s disease continues to deepen. The aim is not to predict the disease but reveal its pathophysiological mechanisms in order to develop new drugs. At Lille’s Institut Pasteur, an Inserm team led by Jean Charles Lambert within Inserm Unit 1167 “Risk factors and molecular determinants of diseases linked to aging” directed by Philippe Amouyel recently hit a new milestone thanks to the Genomics of Alzheimer’s Project (IGAP), in which the genomes of 94,000 people were analyzed. This research revealed five new genetic variants linked to the disease.

Brain Prize 2019 a French team receives international award for his research on CADASIL, a hereditary cerebrovascular disease

(Français) Attribué par la fondation Danoise Lundbeck, le « Brain Prize » est un grand prix international qui récompense des scientifiques pour l’importance de leurs recherches en neurosciences. Il est doté d’un montant d’un million d’euros.
Il met cette année à l’honneur des travaux débutés il y a près de quarante ans par quatre scientifiques français sur CADASIL, une maladie cérébrovasculaire héréditaire, qui provoque crises de migraine, accidents vasculaires cérébraux et déclin cognitif. C’est aujourd’hui la maladie génétique des petits vaisseaux cérébraux la plus fréquemment diagnostiquée.

Behind a Rare Disease: A Gut Sensitive to the Cold and Intolerant of its Own Bacteria

A mechanism of tolerance towards intestinal flora is thought to be implicated in the onset of a rare familial autoinflammatory disease induced by cold temperatures. This is the finding of researchers from the Center for Infection and Immunity of Lille (Inserm/Université de Lille/CNRS/University Hospital Lille/Institut Pasteur de Lille), the Pathophysiology of Pediatric Genetic Diseases laboratory (Inserm/Sorbonne Université) and the Department of Immunology at the University of Hohenheim. Their research, published in Nature Communications, reveals the implication in its onset of an exacerbated inflammatory response against the gut flora, making for a more effective immune response against certain pathogens.

Expertise caregivers helps improve patient diagnosis in altered state of consciousness

Hospital teams Pitié-Salpêtrière Hospital AP-HP, Inserm and the Institute of the brain and spinal cord – AP-HP / CNRS / Inserm / University-Sorbonne showed appreciation caregivers (nurses and nursing auxiliaries) for the state of consciousness of patients represented a real added value to medical and electrophysiological exams and conventional brain imaging diagnostics.

Syndrome Temple and Silver Russell understanding of epigenetic mechanisms regulating fetal growth

A team Sorbonne / AP-HP / Inserm, led by Professor Irene Netchine, physiology professor at Sorbonne University and pediatrician at the Hospital Armand Trousseau AP-HP, studied the molecular mechanisms of the clinical similarity between syndrome Temple and Russell Silver syndrome. Their study, published in Science Advances , highlights the importance of gene network concept “imprinted” in the diagnosis and treatment of patients with these rare syndromes.
