Researchers from SB2SM (I2BC@Saclay) have shown for the first time in vivo in the model cyanobacterium Synechocystis that a cellular detoxification enzyme, the membrane glutathione-S-transferase (GST), maintained in part by evolution, plays a major role in resistance to thermal and oxidative stress, making this cellular model a valuable tool for the study of GSTs conserved from bacteria to plants, down to Humans.
Radiochemists from the BioMaps unit (SHFJ) have developed and automated a new fluor-18 radiolabelling method for peptides used to characterize specific pathological molecular signatures and thus target treatments. Peptides were conjugated to a specific tag, then radiolabeled in a single step under mild conditions, making this approach an innovative solution for PET imaging of peptides labeled with fluorine-18.
A team from NeuroSpin, in collaboration with researchers from the Sainte-Anne Hospital and from the University of Minho, has developed, using magnetic resonance imaging, a unique set of resources for the analysis and visualization of preclinical data in the rat brain.
NeuroSpin researchers have developed a software for preprocessing non-human primate brain raw images obtained by functional magnetic resonance imaging. The aim is to help harmonize methods, improve procedures, facilitate comparison and interpretation of the acquired images and to minimize the number of animals to be used in research.
Researchers from IRAMIS collaborated with a team from SPI (LERI) for the development of a microfluidic biochip ("lab-on-chip") based on ultra-sensitive magnetic sensors with giant magnetoresistance (GMR sensors), capable of individually and effectively detect magnetically-labeled biological targets.
A team from SCBM, in collaboration with Mauritian modelers, has shown that carboxylic acids can be easily converted into small rings with four carbon atoms, the cyclobutanes, using blue LEDs and an iridium catalyst. Cyclobutanes are increasingly used in the design of new drugs and the method described here will help to significantly expand the chemical space explored in "drug discovery".
A team from SIMoS (DMTS) developed, as part of a collaborative study, the first 99mTc-labeled radiotracer specific for an extracellular enzyme, MMP-12, overexpressed in many inflammatory processes, including abdominal aortic aneurysm. This radiotracer, which preferentially marks the aneurysm in an animal model, will be a promising tool for molecular imaging of the various pathologies in which MMP-12 is involved.
A team from SPI, in collaboration with the metabolic biochemistry service and the Institute of Memory and Alzheimer's Disease (IM²A) of the university hospitals Pitié-Salpêtrière, has developed a method for the simultaneous quantification of tau and α-synuclein proteins in human cerebrospinal fluid by high-resolution mass spectrometry. A promising new approach for the differential diagnosis of Lewy bodies dementia and Alzheimer's disease.
A team from I2BC@Saclay, in collaboration with the CNRS (ICMMO, UPSud and ISM2, Aix-Marseille University) has shown that the use of a reversible electron acceptor, able to accept and transfer an electron, in place of a sacrificial electron donor optimizes efficient and clean photocatalysis reactions for the production of organic compounds of interest.
Researchers at BIAM and I2BC@Saclay, in collaboration with Japanese colleagues from Okayama University and Ehime, have characterized in a cyanobacterium a minor protein that diverts part of the energy from photosynthesis to secondary metabolic pathways. This discovery is promising to exploit these metabolic pathways in a biotechnological process of bioenergy production.
