A Bacterium to Protect the Microbiota from the Harmful Effect of Food Additives
Emulsifiers are food additives that are used to improve texture and extend shelf life. They are found in many processed products (ice cream, packaged cakes, sauces, etc.) despite having demonstrated harmful effects on intestinal balance. In a new study, scientists from Inserm, CNRS and Université Paris Cité at Institut Cochin in Paris sought to counteract these effects by using Akkermansia muciniphila, a bacterium naturally present in the intestine, to repopulate and thus strengthen the intestinal epithelium. The addition of this bacterium to the gut microbiota is thought to prevent the damage caused by the consumption of emulsifiers.

Predicting the Onset of Anxiety Disorders in Adolescence Thanks to Artificial Intelligence
For the first time, a team led by Inserm researchers Jean-Luc Martinot and Éric Artiges at the Developmental Trajectories and Psychiatry laboratory (Inserm/ENS Paris-Saclay) and the Borelli Center (CNRS/Université Paris-Saclay) looked for factors that would predict the onset of anxiety disorders in adolescence. They monitored the mental health of a group of adolescents aged 14 to 23. Thanks to artificial intelligence, they have identified the warning signs most predictive in adolescence of the onset of anxiety disorders in these young adults.

Fathers Who Take 2 Weeks Paternity Leave Are Considered Less Likely to Develop Postpartum Depression
In the weeks that follow the birth of a child, both parents are likely to develop depression. Paternity leave, recognized for its benefits on family balance, child development and male-female equality, could be one of the keys to preventing this condition that affects one in ten fathers and almost two in ten mothers.

Trial on safety and immunogenicity of Ebola vaccines yields promising results
Ebola epidemics occur periodically in various sub-Saharan African countries. While vaccines exist and have already received WHO Prequalification against the Zaire ebolavirus species, it is essential to pursue and intensify efforts to supplement the available data to develop a safe and effective Ebola vaccine strategies in adults and children alike. The PREVAC international consortium, which includes scientists from Inserm and from institutions in Africa, USA and UK, has published the results of a large-scale randomized clinical trial in West Africa in the New England Journal of Medicine.

2022 Inserm Prizes: Forming a Common Front for Our Health
This year, the Inserm Prizes are awarded to five individuals whose results and commitment to high-quality research demonstrate scientific excellence and the Institute’s central place in society. The Inserm 2022 Grand Prize goes to Olivier Delattre, an oncopediatrician whose work has led to major discoveries in childhood cancers.

ASD: Towards a Better Understanding of the Molecular Mechanisms of Autism
While great progress has been made in recent years in the understanding of autism spectrum disorder (ASD), its underlying molecular mechanisms remain fairly poorly documented. Several hypotheses have been put forward regarding the possible dysfunction of certain neurotransmitters in the brain, but rigorous scientific studies are still lacking in order to validate them. In […]

Tuberculosis: children hospitalized with severe pneumonia in high-incidence countries should be screened for TB
La tuberculose touche 1 million d’enfants chaque année dont moins de la moitié sont diagnostiqués et traités, ce qui entraîne plus de 200 000 décès par an. Dans une nouvelle étude, des chercheurs et cliniciens de l’Université de Bordeaux, de l’Institut de recherche pour le développement (IRD) de l’Inserm et MU-JHU (collaboration de recherche entre l’Université de Makerere et l’Université de John Hopkins en Ouganda) regroupés au sein du consortium TB-Speed, ont montré que le dépistage de la tuberculose à l’admission des enfants souffrant de pneumonie sévère était faisable. Par ailleurs, un tel dépistage avec un test appelé l’Xpert Ultra permettrait d’améliorer le diagnostic de la tuberculose chez les enfants des pays à forte incidence de la maladie. Les résultats de l’étude plaident en faveur d’une utilisation plus systématique de l’Xpert Ultra, chez ces enfants, notamment chez ceux souffrant de malnutrition aiguë sévère.

A New Gene Therapy Strategy for Sickle Cell Disease and Beta-Thalassemia
Both sickle cell disease and beta-thalassemia are genetic disorders that affect hemoglobin, and as such are categorized as beta-hemoglobinopathies. A team of scientists from Inserm, Université Paris Cité and the Paris Public Hospitals Group AP-HP at the Imagine Institute has shown the efficacy of a gene therapy approach to treat these two disorders. The principle is to reactivate in patients the production of fetal hemoglobin, a protein whose expression usually ceases after birth.

Alzheimer’s disease: newly identified rare gene variants significantly increase the risk of developing this pathology.
An international consortium has identified rare variants in two new genes that markedly increase the risk of developing Alzheimer’s disease (AD). The work was led by two research groups in France (headed respectively by Gaël Nicolas, Rouen and Jean-Charles Lambert, Lille) and a group in the Netherlands (headed by Henne Holstege, Amsterdam). The new results provide a better understanding of the genetics of AD and open up new research themes on more relevant in vitro and in vivo models. The consortium’s findings are also likely to catalyze the development of new strategies for treating AD.

Research shows fatty liver disease endangers brain health
People with liver disease caused by eating too much sugar and fat could be at increased risk of developing serious neurological conditions like depression or dementia. In a study examining the link between non-alcoholic fatty liver disease (NAFLD) and brain dysfunction, scientists at the Roger Williams Institute of Hepatology, affiliated to King’s College London and the University of La²usanne, found an accumulation of fat in the liver causes a decrease in oxygen to the brain and inflammation to brain tissue – both of which have been proven to lead to the onset of severe brain diseases.
