To carry out their activities, Research Teams of the Frédéric Joliot Institute for Life Sciences have developed high-profile technological platforms in many areas : biomedical imaging, structural biology, metabolomics, High-Throughput screening, level 3 microbiological safety laboratory...
All the news of the Institute of life sciences Frédéric Joliot
Researchers from the MIND team (NeuroSpin) and the Neuroscience Center in Helsinki describe a machine learning model that simplifies the interpretation of stereo-electroencephalography (SEEG) data acquired during the presurgical evaluation of drug-resistant epilepsy. This approach improves and facilitates the localization of the epileptogenic network.
Researchers from our DMTS department have published a study providing the first proof of concept for a CAR-macrophage therapy targeting the endothelin B receptor, which is overexpressed in melanoma cells.
Researchers from the DMTS have developed a method for exploring the chemical exposome in large, complex mass spectrometry datasets. They applied it to the analysis of meconium samples from a cohort.
Researchers from BAOBAB (NeuroSpin) have demonstrated that cortical folding is indeed a biomarker of brain development and that its genetic influences can be detected using deep learning methods.
A collaborative study between the BIAM and Joliot (SPI/DMTS) institutes demonstrates the feasibility of near-complete whole-body carbon-13 isotopic labeling in mice and lays the foundation for a global, quantitative, and unbiased metabolomics approach. This unprecedented strategy could also enable the investigation of certain metabolic troubles.
DMTS teams have characterised 17 monoclonal antibody-candidates targeting ricin using two original biophysical approaches. The identification of ricin residues involved in functional antibody recognition paves the way for the development of powerful monoclonal therapeutic antibodies against this natural toxin, which is a bioterrorism agent.
A team from I2BC has uncovered the key steps governing the assembly and regulation of iron–sulfur cluster biosynthesis, essential metallic cofactors involved in numerous biological functions. Defects in this process lead to pathologies such as Friedreich’s ataxia. These studies represent major advances toward the development of future therapies.
Peptides and proteins adsorb onto plastic nanoparticles, forming a corona. Researchers from I2BC and CEA-Iramis, using molecular modeling, reveal distinct adsorption behaviors depending on their amino acid sequences. They thus establish a mechanical basis for predicting peptide-plastic interactions, a crucial element for assessing the risks these interactions pose to health and ecosystems.
Researchers from the I2BC show that two Arabidopsis thaliana mutants deficient in manganese transport do not regulate photosynthetic electron transport in the same way, with different consequences for photosynthesis.
A team from NeuroSpin investigated the impact of contrasting auditory environments on the morphology of the superior temporal sulcus (STS) in preterm newborns. By showing that exposure to music is associated with a deeper STS, the authors suggest that early auditory experience influences the structural development of temporal brain regions.
A team from NeuroSpin sheds light on the mechanisms underlying artifacts caused by intra-voxel dephasing, which occur when using ultra-high-field MRI acceleration methods such as GRAPPA.
Researchers from the BioMaps laboratory (SHFJ) demonstrate the value of artificial intelligence software in interpreting MRI data for monitoring individuals with multiple sclerosis. However, validation by clinical radiologists remains essential to ensure the accuracy of the interpretation.
A LI-MS team presents an innovative strategy and software for structural elucidation in metabolomics using tandem mass spectrometry.
Une équipe du LI-MS (SPI/DMTS) combine un protocole robuste d’immunoprécipitation de l’alpha-synucléine à de la spectrométrie de masse haute résolution et caractérise des formes tronquées inédites de la protéine.
The CEA is revealing a series of in vivo human brain images acquired with the Iseult MRI machine and its unmatched 11.7 teslas magnetic field strength. This success is the fruit of more than 20 years of R&D as part of the Iseult project, with one pillar goal being to design and build the world’s most powerful MRI machine. Its ambition is to study healthy and diseased human brains with an unprecedented resolution, allowing us to discover new details relating to the brain’s anatomy, connections, and activity.
In an article in the New York Times, Stanislas Dehaene (NeuroSpin director) and Mathias Sablé-Meyer (PhD student) discuss recent results obtained in collaboration with the Collège de France, the CNRS and the University of Paris 8 that show that humans have a universal capacity to understand abstract geometric concepts.
September 2021, the 11.7 Tesla MRI of the Iseult project, the most powerful in the world for human imaging, has just unveiled its first images.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
