SIMoS researchers, in collaboration with Genopole, Excellgene, Vaxeal holding SA (Switzerland), used a large-scale approach to map and characterize the response of CD4 T-cells from healthy donors, against two proteins from the Ebola-Zaire virus. They observed a strong response to the viral nucleoprotein (NP) and suggest that components of NP may be included in the design of new Ebola vaccines.
SPI researchers show for the first time, in a mouse model, the induction of cross-protection against Salmonella and Shigella infections, two pathogenic bacteria responsible for gastrointestinal diseases (typhoid, dysentery among others), one of the main causes of morbidity and mortality in several regions of Africa and Asia.
In two articles published in PLoS ONE, researchers at NeuroSpin show that diffusion MRI can monitor astrocyte activity in the brain in a non-invasive way, allowing a better understanding of its involvement in the glymphatic system and in functional MRI.
SPI researchers (Marcoule) used proteomics to identify signature peptides of the SARS-CoV-2 virus expressed in vitro. A "short list" of 14 identified and characterized peptides allows to consider developments in targeted mass spectrometry, making this direct and rapid large-scale approach, implantable in hospitals, a potential tool of choice in the detection of the virus responsible for Covid-19.
Using public MRI data sets from the knee and brain, researchers from NeuroSpin and Cosmostat (CEA-Irfu) have written a consistent benchmark of several deep neural networks used for image reconstruction with significantly reduced acquisition time.
Researchers from the SCBM in collaboration with teams from IRAMIS, AstraZeneca and the Karolinska Institutet have developed a second marking method based on the dynamic exchange of carbon dioxide, this time without catalysis, by "simple" thermal heating. Ideal for organic molecules of therapeutic interest, the method is described in tAngewandte Chemie.
A team from SCBM, in collaboration with researchers from I2BC, SHFJ and IRAMIS, has synthesized new neutral macrocycles called bambusurils (BUs). These BUs can be functionalized by “click chemistry” to obtain multivalent architectures decorated with 8 to 12 ligands of interest, an alternate topology which gives them remarkable supramolecular properties.
A collaboration led by I2BC researchers presents, in the Journal of Experimental Botany, a body of evidence for a dynamic association of the PTOX protein with thylakoid membranes, dependent on proton motive force.
In a study conducted by a team from the Institut Curie, I2BC researchers have used their NMR know-how to study the phosphorylation of BRCA2 and have thus contributed to revealing a mechanism potentially at the origin of chromosomal aberrations observed in breast BRCA2-mutated tumors.
A collaboration between researchers from I2BC@Saclay, the french Muséum National d'Histoire Naturelle and owners of prehistoric sites shows the possibility of using a mobile laboratory to quickly identify DNA of archaeological specimens.

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.
