Alzheimer's disease (AD) is one of the greatest scientific and socio-economic challenges of the 21st century. Currently, there is no cure. Aggregates of amyloid-β and tau proteins, along with neuroinflammation/gliosis, are hallmarks of AD that lead to synaptic and neuronal loss as the basis for cognitive decline. The latter is closely related to the brain distribution of tau aggregates, strongly suggesting a link between tau accumulation and synaptic degeneration.
Brain apolipoprotein E (ApoE), primarily produced by astrocytes, is crucial for lipid transport to neurons and synaptic functions. The ApoE4 isoform is the most significant genetic risk factor for AD and contributes to tau-mediated neurodegeneration. Determining how ApoE4 controls tau-mediated synaptic degeneration is essential to understand AD and develop effective treatments, requiring a precise characterization of ApoE4 functions at the synaptic level in tau-damaged synapses.
As a result, the candidate will be involved in a project funded by the ATIP-Avenir program aimed at elucidating the protein partners of ApoE4 underlying tau-mediated synaptic degeneration in AD. To achieve this, the candidate will identify proteomic changes caused by ApoE4 in tau-damaged synapses, combining chemogenetic and proteomic approaches with synaptic resolution. The project involves working with genetically modified mice and analyzing brain phenotypes using proteomic, biochemical, molecular, cellular, and histopathological approaches.
Contexte de travail The INP is a center of training and research that combines basic and translational research to study the organization, function and interaction of neural cells, as well as the molecular and cellular basis of major brain diseases. The INP is part of the Centre of Excellence in Neurodegeneration (CoEN) and offers an internationally competitive research environment with state-of-the-art facilities. The postdoc will be supervised by Dr. Maud Gratuze. The project will be developed at the Faculty of Medicine, located in the centre of Marseille, a few kilometers from the magnificent seafront, the Calanques National Park and the charm of inland Provence, all ideally suited to outdoor and cultural activities.
