A team from I2BC used ultrafast stimulated Raman spectroscopy under resonance conditions enabling the selective observation of vibrational contributions from the various excited states following photon absorption and reveal the vibrational signatures of three optically dark excited states in carotenoids.
Using high-resolution electroencephalography, a team from NeuroSpin has identified a significant link between the power of beta brain waves and hyper- and hypo-sensory particularities in autistic individuals aged between 5 and 17.
An I2BC team has studied, using both in vitro and in silico approaches, the dynamics of phosphatidylserine transport between the endoplasmic reticulum and the plasma membrane in the yeast S. cerevisiae. Their study reveals that the protein Ist2 exhibits lipid scramblase activity and identifies a functional partnership between Ist2 and the lipid transfer protein Osh6.
Researchers from BioMaps, NeuroSpin and the Paris Psychiatry & Neurosciences University Hospital Group have unveiled the results of a two-year longitudinal study highlighting differences in white matter bundle alterations between patients with Alzheimer’s disease and those with LATE amnesia.
Researchers from DMTS designed bifunctional PROTAC chemical probes to identify the molecular target(s) of Retro-2 compounds, broad-spectrum inhibitors of intracellular pathogens. Although this approach did not identify new Retro-2 targets, it revealed a molecular glue effect involving the protein GSPT1.
A team from NeuroSpin measured brain connectivity patterns using functional MRI data from a deep-phenotyping dataset involving several tasks (watching movies, listening to stories). The authors showed that sparse partial correlation is more effective for identifying individuals, whereas standard correlation performs better for distinguishing and classifying different cognitive tasks
A team from NeuroSpin designed an original learning paradigm to identify the brain code representing the probability of an event occurring. Results obtained using ultra-high-field functional MRI show that fronto-parietal regions encode this probability and that its representation relies on a highly non-monotonic code.
A team from the SPI (DMTS) investigated the effects of hypoxia on the interface between the choroid plexus and cerebrospinal fluid using organoids derived from human pluripotent stem cells. The aim was to investigate how cerebral hypoxia at birth, which causes hypoxic-ischaemic encephalopathy, disrupts this cerebral barrier, which has not yet been extensively studied.
Researchers from NeuroSpin demonstrate that cortical folding, analyzed using deep learning, holds promising potential for predicting psychiatric disorders. They highlight the value of pre-training to build foundation models on large cohorts and the benefits of a regional approach.
Researchers from DMTS have demonstrated that the quality of proteomic analyses can be significantly improved by optimizing the protein digestion step of a sample. Within the framework of a rapid and automatable technique (SP3), selecting the appropriate magnetic beads and adjusting the protein-to-bead ratio proves to be a winning strategy.
