Researchers from SCBM, in collaboration with Paris-Sud University and INSA Toulouse, developed the first general method for tritium and deuterium labeling of complex molecules with thioether-type motifs (including sulfur atom). This method allows rapid access to tritiated or deuterated molecules used in the pharmaceutical industry for in vivo monitoring or the biological assay of substances of interest.
Two Research Teams from SIMOPRO and SCBM, in collaboration with Texas Biomedical Research Institute and Jilin University, showed that anti-ricin compounds Retro-2, discovered at CEA during researches against bioterrorism, inhibit two families of viruses important for public health (Ebola and Marburg filovirus and enterovirus EV71). These results broaden the antiviral spectrum of Retro-2 type compounds.
Misspelled WordNeuroSpin researchers, in collaboration with two German Research Teams in the context of the Human Brain Project (HBP), offer a mapping of the hippocampus with unprecedented resolution, thanks to the very high field MRI, revealing not only its sub-structures, but also its internal neuronal connections and its cellular composition.
Researchers from NeuroSpin (UNICOG) highlighted how the specific region of word recognition develops during the process of learning to read among children during first grade. This work, which helped to locate a "mailbox" in the left hemisphere, was published in the journal PLOS Biology and was the subject of a press release on March 13, 2018.
Muriel Gondry's Research Team (I2BC@Saclay / SBIGeM), in collaboration with SIMOPRO and Biomolecules Laboratory of the Sorbonne University's one, produced 200 cyclodipeptides containing non-natural amino acids by luring and diverting the cellular machinery for the synthesis of proteins. This unprecedented approach significantly increases the diversity of these bioactive molecules.
Research Teams from SHFJ, MIRCen and NeuroSpin tested a pharmacokinetic analysis model of Positron-emission tomography (PET) data at 18F-DPA-714, taking into account endothelial cell activity not specifically associated with an inflammatory state. This model allows a more precise interpretation of PET images of neuroinflammation present in most neurodegenerative pathologies.
A Research Team from I2BC@Saclay (SB2SM), in collaboration with ISMO and ICMMO teams (CNRS / Univ.Paris-Sud, Univ.Paris-Saclay) measured accumulation kinetics of electrical charges within a molecular system designed for studies on artificial photosynthesis. These works, published in Angewandte Chemie, show for the first time the second electron of this fundamental process about the conversion of light energy into fuel.
Researchers from NeuroSpin (Frédéric Joliot Institute/CEA) and MIRCen (François Jacob Institute/CEA Institute of Biology) have just developed an ultrasound device guided by magnetic resonance imaging (MRI) to increase temporarily and locally the vascular permeability in non-human primates, which could be used to effectively deliver drugs to the brain.
In collaboration with a German Research Team from Marburg University, Pavel Müller and Klaus Brettel (I2BC @ Saclay / SB2SM) have studied the first steps of photoactivation of a Class II photolyase of the Methanosarcina mazei archaeobacteria by resolute optical spectroscopy time and discovered a peculiarity of this class of photolyases: photoinduced separation of charges is stabilized by a water cluster, a structural element also preserved in class II photolyases of plants and animals.
According to a study published in the Journal of Nuclear Medicine, Irène Buvat's Research Team (IMIV, SHFJ), in collaboration with the Vincent Frouin's one (UNATI / NeuroSpin) proposed an unprecedented imaging approach based on the use of the ComBat harmonization method derived from genomics. This method correctly estimates the "center" effect that affects the images and thus makes it possible to analyze together radiomic biomarkers of positron emission tomography (PET) images from different centers.

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.
