Mieux comprendre divers processus invisibles à l’œil nu, qui ont lieu à l’échelle de nos cellules, grâce à un minuscule robot construit à base d’ADN... Si cela s’apparenterait presque à un projet de science-fiction, il s’agit en fait de travaux très sérieux menés par des scientifiques. Ce « nano-robot », très innovant, devrait permettre d’étudier de plus près des forces mécaniques qui s’appliquent à des niveaux microscopiques et qui sont cruciales...
Myotonic dystrophy type 1 (DM1) or Steinert’s disease is a rare and debilitating genetic neuromuscular disease affecting multiple organs and with a fatal outcome. No treatment is available at present. Encouraged by previous research into its molecular causes, researchers have developed and tested a promising gene therapy that acts directly at the origin of the disease. Initial findings show correction of molecular and physiological alterations in mouse skeletal muscle1.
The zebrafish is particularly studied in research laboratories due to its ability to regenerate its caudal fin. This study opens up new avenues for improving our understanding of the regeneration processes, with the aim of developing clinical applications in the field of regenerative medicine.
A new test to detect antibodies to SARS-CoV-2 that is reliable, inexpensive and needs no special equipment? This is the proposal of an international scientific team, of which one of the members is an Inserm researcher at the Institute of Pharmacology and Structural Biology (CNRS/Université Toulouse III - Paul Sabatier). Developed in collaboration with the University of Oxford, this serological test is based on a single reagent that causes...
Endocrine disruptors can potentially become more harmful if mixed. Following on from research published in 2015, scientists continue to decipher the molecular mechanisms behind this phenomenon known as the "cocktail effect".
Understanding the three-dimensional structure of DNA and RNA and how they interact with other molecules is necessary for the advancement of biomedical research and drug development. A team led by Inserm researcher Valérie Gabelica at the Nucleic acids: natural and artificial regulation laboratory (ARNA, Inserm/CNRS/Université de Bordeaux)[1] has developed an innovative method pairing mass spectrometry with circularly polarized light, enabling better characterization of these different molecular interactions.
Malaria infection during pregnancy represents a major public health problem in the regions endemic for the disease, substantially increasing the risks to mothers and their unborn children. For newborns, malaria is linked to low birth weight and an excess risk of mortality. To protect this population, a team of researchers is developing a vaccine at the French National Institute of Blood Transfusion (INTS).
Atopic dermatitis, or eczema, primarily affects infants and children, and manifests itself in hypersensitivity to allergens in the environment. A skin disease characterized by flare-ups, it is often treated with topical anti-inflammatories. A new study shows that immune cells and sensory neurons interact in the skin to form units that can detect allergens and trigger inflammation. A discovery that provides an insight into how atopic dermatitis works, and points...
Alors que les méthodes d’apprentissage automatique sont utilisées dans de nombreux domaines, y compris la santé humaine, leur application au monde du vivant est peu explorée à l’échelle moléculaire. Des chercheurs de l’Inra et de l’Inserm, viennent de réaliser un premier pas dans cette direction en créant un réseau neuronal simple dans un extrait cellulaire de bactérie Escherichia coli.
The global spread of antibiotic resistance is a major public health issue and a priority for international microbiology research.
