Researchers from BioMaps (SHFJ) investigated the hepatic activity of organic anion-transporting polypeptides (OATPs), key players in the elimination of certain drugs, using a PET imaging approach with 11C-glyburide, which revealed differences in tracer pharmacokinetics between men and women.
Researchers from IRAMIS and SPI (DMTS) evaluated their GMR-sensor biochip prototype for its ability to detect cancer cells in a complex medium. This approach, which combines sensor physics with medical biology, aims to develop simpler and portable diagnostic tools that meet the WHO criteria for point-of-care testing.
Researchers from SIMoS (DMTS) contributed to the characterization of a nanobody (VHH) designed by scientists at the Institut de Génomique Fonctionnelle in Montpellier. They performed tritium labeling and biodistribution tracking of this VHH, which can specifically activate a glutamate receptor involved in schizophrenia. This work was published in Nature.
A study led by the I2BC shows that the formation of condensates of the enzyme KIF2C enables the concentration of two other proteins, PLK1 and phosphorylated BRCA2, on kinetochore microtubules during mitosis. This would serve to control chromosome alignment on the spindle and contribute to their stability.
Researchers at SPI (DMTS) have developed a high-yield strategy for producing monoclonal antibodies by preselecting the antibody-producing cells most likely to form viable hybridomas. This represents a step toward broader use of this technology, a potential alternative to the use of animals for antibody production.
Scientists at the EPFL, in collaboration with a team from SCBM (DMTS), have developed a new technique that enables, with unprecedented sensitivity, the measurement of circularly polarized light emitted by luminescent materials over time. This work has been published in Nature.
Researchers from BioMaps (SHFJ), NeuroSpin, and the french IRBA developed an innovative approach using focused ultrasound to improve brain delivery of an antidote, oxime, following exposure to an organophosphorus neurotoxic agent in a murine model.
A study combining PET imaging and pharmacology, conducted by researchers at BioMaps (SHFJ), suggests that decreased availability of opioid receptors and altered neuronal energy metabolism constitute molecular signatures of opioid tolerance. These observations, made in an animal model, could help improve understanding and treatment of opioid dependence.
A team from NeuroSpin studied the microstructural and functional connectivity profiles of infants’ brains to understand how these characteristics evolve and relate to each other during early neurodevelopment. The results indicate that connectivity, which is altered by prematurity, strengthens with maturation, and that the associated networks become increasingly similar.
En utilisant Saccharomyces cerevisiae comme modèle, des chercheurs des instituts CEA-Jacob et CEA-Joliot, et de l’Institut Curie, avec leurs partenaires du synchrotron SOLEIL, ont révélé comment la protéine Rad52 agit comme un chaperon pour guider et stabiliser l’assemblage de Rad51, une étape clé de la recombinaison homologue.

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.
