In an article published in the Journal of Medicinal Chemistry, the Venomics consortium led by a SIMoS team shows the interest of creating toxin banks to identify molecules regulating therapeutic targets.
The discovery of myriads of new species of bacteria and archaea, linked to the explosion of metagenomics, is leading microbiologists to consider rethinking how to map certain branches of life. Tools, such as the phylopeptidomics developed at Li2D, could help them do so.
Researchers from the I2BC (SB2SM), in collaboration with CNRS (LCP, ICMMO) have designed an original artificial photosynthesis approach, based on the use of semiconductor nanopolymers composed of PolyDiPhenylButadiyne, capable of reproducing the full photo-redox reaction of plant Photosystem II, that is the production of O2 by photo-oxidation of water and the reduction of a quinone.
In order to optimize the amplification of quality inactivated virus, for the manufacture of a vaccine, a team from SPI (CEA Marcoule) used mass spectrometry to analyze the dynamics of the proteome of SARS-CoV-2 infected cells, at two multiplicities of infection. With more than 3,220 identified host proteins, researchers are also starting to decipher the processes and cellular networks impacted by this virus.
Researchers from the BioMaps unit based at the SHFJ have developed an imaging protocol to study in vivo the hepatobiliary transport capacity responsible for the elimination of many drugs and to better understand the hepatotoxicity of certain drugs.
Researchers from the LMC have developed a new series of iminosydnones that can split in two and release two fluorophores. They are providing a proof of concept that this "click and release" reaction can be triggered in living cells.
SIMoS researchers, in collaboration with Genopole, Excellgene, Vaxeal holding SA (Switzerland), used a large-scale approach to map and characterize the response of CD4 T-cells from healthy donors, against two proteins from the Ebola-Zaire virus. They observed a strong response to the viral nucleoprotein (NP) and suggest that components of NP may be included in the design of new Ebola vaccines.
SPI researchers show for the first time, in a mouse model, the induction of cross-protection against Salmonella and Shigella infections, two pathogenic bacteria responsible for gastrointestinal diseases (typhoid, dysentery among others), one of the main causes of morbidity and mortality in several regions of Africa and Asia.
In two articles published in PLoS ONE, researchers at NeuroSpin show that diffusion MRI can monitor astrocyte activity in the brain in a non-invasive way, allowing a better understanding of its involvement in the glymphatic system and in functional MRI.
SPI researchers (Marcoule) used proteomics to identify signature peptides of the SARS-CoV-2 virus expressed in vitro. A "short list" of 14 identified and characterized peptides allows to consider developments in targeted mass spectrometry, making this direct and rapid large-scale approach, implantable in hospitals, a potential tool of choice in the detection of the virus responsible for Covid-19.

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.
