To celebrate the remarkable work of NeuroSpin researchers over the past 10 years, a day of high-level scientific conferences was held on the 16th of February at NeuroSpin under the leadership of its director, Stanislas Dehaene.
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.
Julie Soutourina (I2BC@Saclay / SBIGeM) was invited by Nature Reviews Molecular Cell Biology to publish a review on the molecular functioning of the Mediator, a multi-protein complex, conserved from yeast to humans, and essential to the regulation of the expression of genes. Potential therapeutic approaches targeting the Mediator (cancer, fungal infections) are also adressed.
A SIMOPRO Research Team, in collaboration with a SCBM Team, has identified, by screening a library of small chemical molecules, a compound capable of reducing the sensitivity of cells to a plant toxin, that is ricin. By collaborating with seven Teams of microbiologists, researchers have shown that this compound, called ABMA, protects cells by blocking an intracellular transport pathway borrowed by many other bacterial and intracellular pathogenic toxins. ABMA defines a new family of broad-spectrum anti-infective agents.
