Improving our knowledge of the development of the complex structures of the human head to shed new light on the congenital abnormalities that cause malformations: this is the challenge that a team of researchers from Inserm, CNRS and Sorbonne Université at the Vision Institute, Université Claude Bernard Lyon 1 and Hospices civils de Lyon is well on its way to fulfilling. Thanks to an innovative technique in which the...
Throughout 2023, and as Inserm prepares to celebrate its 60th anniversary next year, its staff has continued to promote the health of all citizens thanks to major advances across all areas of biomedical research. The work of the five scientists selected to receive this year’s prizes reflects the rich and innovative nature of Inserm research. The Inserm Grand Prize is awarded to Nadine Cerf-Bensussan, a pioneer in the exploration...
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...
urrently, the treatment of heart valve diseases relies on the replacement of the dysfunctional valve with an artificial prosthesis. However, this procedure cannot be offered to all patients due to its invasive nature. In a new study, a group of researchers from laboratories shared by Inserm, ESPCI Paris, CNRS and Université Paris Cité, in close collaboration with the start-up Cardiawave spin-off of the Georges Pompidou European Hospital and the...
French, Singaporean and British researchers, led by Prof. Florent Ginhoux, head of a research team at Gustave Roussy/Inserm, have succeeded in demonstrating in a neuronal organoid the role of the brain's immune environment in its formation and development. The development of these three-dimensional structures integrating neuronal cells and the immune environment is, to date, one of the most complete in vitro models of the human brain.
Neuroscientists from Inserm, CNRS and Université de Bordeaux in France, along with Swiss researchers and neurosurgeons (EPFL/CHUV/UNIL), have designed and tested a "neuroprosthesis" to correct the gait disorders associated with Parkinson's disease. In a study published in Nature Medicine, the scientists describe the development process of the device they used to treat a Parkinson’s disease patient for the first time, enabling him to walk fluidly, confidently, and without falling.
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 several European countries where the incidence rates of sudden infant death syndrome (SIDS) are high, a high frequency of unsafe parental sleep practices has also been observed. In addition, it is known that pictures conveying implicit or explicit health messages can lead to the modification of health practices. Researchers from Inserm, Université Paris Cité and HEC Paris, in collaboration with the Greater Paris University Hospitals (AP-HP), Nantes University...
The association between sleep disorders and cardiovascular risk is already well documented. Apnea, sleep deficit, and insomnia are linked to an increased risk of cardiovascular diseases and stroke. A new study has now explored this association in much greater depth.
When we sleep we are not completely cut off from our environment: we are still able to hear and understand words. These observations, resulting from the close collaboration between researchers from Inserm, CNRS, Sorbonne Université and AP-HP at the Brain Institute and the Department of Sleep Disorders at Pitié-Salpêtrière Hospital in Paris, call into question the very definition of sleep and the clinical criteria that distinguish between its different...
