All the news of the Institute of life sciences Frédéric Joliot
I2BC researchers unveil an atomic model of the hepatitis E virus replication polyprotein obtained with the AlphaFold artificial intelligence program. The model provides a better understanding of how this RNA virus multiplies its genome in infected cells.
Researchers at the Joliot Institute have developed two new families of iminosydnones that allow the bio-orthogonal release of electrophilic species. These molecules constitute "building blocks" of click-and-release chemistry, useful for reactions with nucleophilic compounds contained in cells.
Using molecular dynamics simulation and NMR studies, I2BC researchers detail the restriction mechanisms of BAF protein dynamics due to its phosphorylation.
The protocols applied for in vivo mapping of nuclear processes, at the genome scale and at very high spatial resolution, do not allow for high temporal resolution. A team from the I2BC has therefore demonstrated that such an understanding could be wrong by using a mathematical model. This model can be applied to any process that can be modeled by a transition between two states.
A team from SBIGeM (I2BC) shows, by several spectroscopic approaches, that the assembly of a Fe-S cluster, the catalytic center of many essential proteins, is a highly conserved process, initiated by the insertion of ferrous iron at the cysteine-rich assembly site of the scaffold protein ISCU (Iron-sulfur cluster assembly enzyme).
A Li2D team has released the peptidomic profile of the virus that causes monkeypox, which they established using tandem mass spectrometry. These data should help to better understand the evolution of the epidemic and allow the creation of targeted tests to potentially detect the threat more quickly and prevent a new epidemic.
Timo van Kerkoerle, researcher at NeuroSpin, is one of the 408 winners of the prestigious ERC Starting Grant 2022 call of the European Research Council. Another European success for the Institute.
A team from SIMoS (DMTS) identifies and characterizes a toxin isolated from black mamba venom, whose specific anticholinergic properties at the type 2 acetylcholine receptor, a regulator of arterial tone, position it as a potential drug candidate for the treatment of cardiovascular diseases.
A collaboration led by a METRIC team (BAOBAB/NeuroSpin) has undertaken to measure the signal-to-noise ratio (SNR) in MRI at the centre of a spherical phantom at different magnetic field strengths (B0). Their data confirm the theories that SNR increases with approximately the square of B0.
To address the problem of ultre high field MRI signal loss in certain regions of the human body, a collaboration involving the CEA-Joliot, the CEA-Iramis, the Fresnel Institute and Multiwave Imaging has led to the development of a new generation of simple and inexpensive silicon carbide-based pads. The new composition makes the pads invisible to MRI and prolongs their performance when compared to existing solutions.
The expertise of NeuroSpin in diffusion MRI has allowed to establish the first atlas of the anatomical connectivities of the Japanese quail brain at a resolution of 150 m in three dimensions.
A team from SPI used mass spectrometry to analyze the degree of alteration of the intestinal microbiota of Covid-19 patients and to look for signatures of intestinal infection by the SARS-CoV-2 virus. The level of the observed gut dysbiosis would be an indicator of the stage and extent of the infection.
A study led by NeuroSpin researchers proposes an optimized delineation of rare brain tumors, based on a combined approach of object detection and deep learning segmentation in tumor images, a key step in the characterization of cancers.
A collaboration between the SHFJ and the UMR-S 1144 (University of Paris) shows that the deleterious effect of the buprenorphine/benzodiazepine combination would result from the combined action of each drug on its target.
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.
The European Commission once more places its trust on Multiwave company and its partners, Aix-Marseille Université , CEA and Université Catholique de Louvain to revolutionize ultra-high field magnetic resonance imaging of the brain.

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.
