MASH, formerly known as NASH, is a serious chronic liver disease that affects around 4-6% of the world's adult population. A new study reveals that, contrary to what was previously thought, there is not just one form of MASH, but two. They differ both in terms of biological characteristics and progression. One is of genetic origin, while the other is the consequence of metabolic disorders. This discovery, made at...
Nirsevimab is an antibody targeting the respiratory syncytial virus (RSV). Available in France since September 2023, it is indicated in neonates and infants for the prevention of bronchiolitis caused by RSV. However, its widespread use raises the question of the emergence of resistance mutations. The POLYRES study, the largest prospective surveillance study of nirsevimab breakthrough infections to date, has just delivered its conclusions. Scientists have shown that nirsevimab resistance...
The teams from the kidney transplantation department of Necker-Enfants Malades AP-HP hospital, Inserm and Paris Cité University, as part of the Paris Translational Research Center for Organ Transplantation (PARCC), coordinated by doctor Olivier Aubert and Professor Alexandre Loupy conducted a study on the benefit of liquid biopsy (cfDNA) as a technique for predicting kidney transplant rejection.
Cardiovascular diseases represent the leading cause of death worldwide . Preventing cardiovascular risk by identifying the people most susceptible to these diseases is a major public health challenge. In a new study in this field, researchers from Inserm, Université de Lorraine and Nancy Regional University Hospital opted to focus on arterial stiffness and how it changes with age, given that ageing is associated with a loss of arterial flexibility.
The WHO recently classified the Nipah virus (NiV) as one of the eight main emerging pathogens likely to cause major epidemics in the future. In a context where no treatment or vaccine is yet available, a team comprising researchers from Inserm (Unit 955-VRI) and from the Université Paris-Est Créteil (UPEC) is presenting the preclinical results of an innovative vaccine against this virus.
Anaemia is a major public health problem worldwide, affecting around one third of the population. Its causes are multiple, but the most common are a lack of red blood cell production, a lack of iron in the blood, and genetic diseases such as thalassaemia. A better understanding of iron metabolism is essential to improve the care of the many patients affected.
A study led by scientists from INRAE, the Barcelona Institute for Global Health, Inserm, and the Université Sorbonne Paris Nord, has revealed that the time at which we eat could influence our risk of developing cardiovascular disease. This study, carried out on a sample of over 100,000 people from the NutriNet-Santé cohort, followed between 2009 and 2022, suggests that eating a late first or last meal is associated with...
Although a high-fat, low-fiber diet is recognized as promoting cardiovascular diseases such as atherosclerosis, the mechanisms involved have not yet been fully identified. Researchers from Inserm and Université Paris Cité have studied the role of the gut microbiota in the development of atherosclerosis. Their work in mice reveals that the low fiber content of the high-fat diet leads to an imbalance in the gut microbiota, which itself causes systemic...
Although the cecal appendix is no longer considered a vestige of evolution with no particular role, its exact function remains to be discovered and several hypotheses are currently being explored. A research team from Inserm, CNRS, the French National Museum of Natural History (MNHN), Université de Rennes, Sorbonne Université and the Eugène Marquis Center looked at how the presence of an appendix affects the onset and severity of infectious...
In the face of childhood neurodevelopmental disorders, how can we get out of the therapeutic "dead end"? The answer could well be found in the genes of the proteasome – an intracellular mechanism that is responsible for removing defective proteins from the cell.
