Researchers from the Laboratory of Food Immuno-Allergy (SPI/DMTS), in collaboration with the Necker-Enfants Malades Hospital, identify an immune signature of severe asthma (SA) in children, through a non-targeted global analysis of all immune and inflammatory constituents present in blood and bronchoalveolar lavages of children with SA.
Researchers from Li2D (SPI/DMTS, Marcoule) and LSCE have developed an innovative methodology for analyzing soil microbiota based on an optimal computational interpretation of metaproteomic databases, which should lead to a better understanding of the impact of pollutants on soil quality and to the prediction of their restoration potential.
Researchers at NeuroSpin have developed a deconvolution method to estimate from BOLD fMRI data the coupling between neuronal activity and blood flow, the characteristic signals of neuronal activity and the associated brain areas. The work was published in NeuroImage.
Researchers at UNICOG (NeuroSpin) show, using a high-resolution electroencephalographic system, that speech, an extremely complex and variable acoustic signal, is perceived by infants as a sequence of stable and invariant segments through an encoding based on distinctive and orthogonal phonetic features, such as manner and place of articulation, which are secondarily combined into phonemes, such as ″b″ or ″m″.
By solving the three-dimensional structure of a fragment of the BRCA2-HSF2BP complex, a collaboration involving teams from I2BC and ERASMUS MC identifies the precise BRCA2 motif that causes the very high affinity between the two partners and shows that, in vivo, this complex has no function in the recruitment of Rad51 to meiotic sites of homologous recombination.
Researchers from I2BC (CEA-Joliot/CNRS/UPSay, in collaboration with the JP Bourgin Institute and the University of Vilnius, decipher for the first time the energy dissipation process called "singlet fission" in two natural flower carotenoids, a fundamental mechanism for the design of new and more efficient multi-electron photocatalysts.
Researchers at NeuroSpin (CEA-Joliot) propose to automate the classification and recognition of folding patterns on the surface of the cortex that may be related to the occurrence of psychiatric diseases or cognitive disorders using artificial intelligence algorithms. A path towards deciphering the "lines" of the brain.
In a study published in Science of the Total Environment, researchers from SIMoS (DMTS/CEA-Joliot), in collaboration with the Faculty of Pharmacy of Paris and MIRCen (CEA-Jacob) have shown for the first time in an animal model the capacity of Pinnatoxin-G, a marine neurotoxin, to cross physiological barriers to reach its molecular targets.
In a study published in JBC, a team from I2BC/CEA-Joliot, in collaboration with the Beijing Botanical Institute (China), describes for the first time an intermediate state of the light-harvesting antenna of higher plants that provides a better understanding of the changes that take place at the molecular level during the activation of a plant's photoprotection mechanism.
A team comprising iRCM (CEA-Jacob) and NeuroSpin (CEA-Joliot) researchers analyzed the consequences of irradiation on brain development and neurogenesis in a preclinical model. That work, published in Radiation Research, lays a path for the use of diffusion imaging for the early detection of neurological abnormalities resulting from different types of stress.
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.
