An I2BC team has revealed the structure of the C-terminal transmembrane region of the SARS-CoV-2 protein nsp3, essential for virus replication. This region self-assembles into hexamers that form molecular pores on the surface of double-membrane vesicles, the sites of viral genome replication. Nsp3 therefore appears to be a promising therapeutic target.
A NeuroSpin team analyzed the MEG response of volunteers exposed to auditory sequences organized in network. Finding that participants' brain activity was sensitive to the structure of the network, it concluded that learning the structure of auditory sequences involves a single cognitive process, associative learning.
Une équipe du SCBM met au point une méthode d’échange isotopique du soufre pour le marquage de molécules biologiquement actives. Telle une plateforme isotopique multi-échangeable, le procédé permet également un échange isotopique du carbone et d’hydrogène donnant accès à un grand nombre d’isotopologues. L’équipe met en avant le potentiel de la méthode pour vérifier l’authenticité de molécules organiques commerciales.
A collaborative study led by NeuroSpin researchers analyzed anatomical MRI images of 662 young subjects from the Healthy Brain Network cohort, to map different features of cognitive function linked to cerebellar structure. It shows that there is a complex association between key cognitive functions and particular lobules of the cerebellum.
As a stakeholder in the NOMATEN Centre of Excellence for innovative multifunctional materials, the CEA-Joliot Institute supports its development by regularly organizing training sessions for its staff. The latest examples.
A team from I2BC has studied the positioning of nucleosomes in the yeast S cerevisiae genome, using an original mathematical method to analyze next-generation sequencing data. This mapping highlights the role of chromatin remodeling complexes in nucleosome organization.
Teams from I2BC, Institut Curie and IRB shed light on how the human nuclease MRN works. Structural predictions obtained with AlphaFold2 and confirmed by in vitro and in vivo experiments show that the phosphorylated Sae2/CtIP protein forms a network of interactions with MRN that favours the removal of its autoinhibition.
A team from BioMaps (SHFJ) measures for the first time the in vivo local mechanical properties at play in a muscle (elasticity, anisotropy, non-linearity) using a non-invasive method, ultrasonic shear wave elastography. The originality of the approach lies in its ability to perform such measurements in a so complex tissue.
