Team THOUMINE : Postdoc position in Cellular Neuroscience

We are hiring one highly motivated postdoctoral scientist to investigate the molecular, structural and functional organization of the glutamatergic tripartite synapse. In light of recent evidence that astrocytes are not just a mere "glue" surrounding neurons but actively regulate synaptic connections, we want to investigate the molecular interactions that drive and maintain astrocytic processes in close contact with neurons and how those interactions dynamically regulate the structure and plasticity of synapses. To address this question, we will combine whole patch-clamp recordings with single-cell RNA seq (“patch-seq”), proteomics, electrophysiology, expansion microscopy and live microscopy in the mouse hippocampus, where the role of astrocytes in synaptic plasticity is well established. We will further assess the impact of autistic mutations targeting astrocytic protein candidates that have been so far considered only from a neurocentric point of view.

For this project, the candidate should have expertise in either patch-clamp electrophysiology or microscopy and show strong interest in molecular and cellular neuroscience with a focus on neurotransmission and synaptic plasticity. The project is to be developed in the team Cell Adhesion Molecules in Synapse Assembly at IINS of the Bordeaux Neurocampus. The position has 2 years initial funding from ANR.

Candidates should send a CV, a brief statement of research experience and reference letters to Mathieu Letellier:

Team CHOQUET : post-doc positions in synaptic plasticity funded by ERC and ANR

We are seeking to recruit post-doctoral fellows strongly interested in cellular neuroscience, including synaptic plasticity, receptor trafficking and nanoscale organization to join a vibrant environment and exciting projects associating high resolution imaging, biosensors and slice electrophysiology to study innovative aspects of synaptic plasticity. We have developed unique tools to monitor and modify AMPA receptor nanoscale organization and trafficking in vivo and would like now to apply them to study  synaptic function with electrophysiological, molecular and imaging approaches. These approaches may be combined with behavioral assessment of memory function to understand the link between synaptic plasticity and memory storage, consolidation and retrieval.

We have developed innovative tools to study the nanoscale organization of AMPAR subunits and subtypes, to control with light their accumulation or disappearance from synapses during STP, LTP and LTD. We plan to use these tools to analyze the role of synaptic plasticity in information processing by the brain.

Altogether, this project will shine new light on the molecular mechanism of synaptic plasticity and will be linked to behavioral studies of cognitive functions using the same tools.
The position will be financed by ERC and ANR grants from D. Choquet for up to five years.

For this position, we are seeking highly motivated individuals, with a proven track record of success, if possible immediately after their PhD, and in any case no more than four years after their PhD. The projects will be conducted in a stimulating and highly interdisciplinary and international environment in a newly established research building, a part of the Bordeaux neurocampus project (Bordeaux, France).

Team CHOQUET : PhD position

The dendritic spine is a small protrusive structure that is made of a head and a narrow neck emerging from the dendritic shaft. This structure is crucial for neuronal physiology as it is where the postsynaptic compartment of most excitatory synapses is localized and its peculiar shape allows for specific micro-compartmentalization of neuronal signaling. Spine morphology is very plastic; spine head and neck sizes correlate almost perfectly with synaptic strength and spines grow or shrink during synaptic potentiation or depression, respectively. Importantly, the molecular composition and the correlated morphology of spines are critical for synaptic function. Mechano-sensing is emerging as a key mechanism regulating neuronal functions during physiological processes, including neuronal development and synaptic transmission. Despite the fact that they probably involve adhesion and cytoskeleton proteins, the molecular mechanisms underlying neuronal mechano-sensing remain unknown. The overarching objective of this PhD project addresses this precise fundamental question.

In collaboration with the group of Gregory Giannone (IINS), different methods to deform spines by applying external mechanical forces will be used. Their impacts on spine shape, mechanical stability and synaptic transmission will be studied by a combination of molecular tools, electrophysiology and state of the art imaging methods, including super-resolution microscopy but also FRET-based force sensors imaging.

As a first molecular target for mechanical regulation/transduction of dendritic spines, the PhD student will study the role of a major class of cytoskeletal protein called β spectrins. Spectrins have actin-binding domains at their ends and various membrane-interacting sites along their length. Spectrin's functions are best characterized in erythrocytes, where the 2D membrane-bound actin-spectrin network maintains the biconcave cell shape and provides mechanical support. Spectrins are also present in other cells and are especially important for the nervous system. In fact, several pathogenic variants have been recently described in central nervous system diseases including developmental delay and autistic features. The emergence of super-resolution microscopy in the past years uncovered the peculiar organization adopted by actin and β spectrins in neurons at the nanoscopic level. A ring-like actin-spectrin network structure appears in axons with 180–190nm periodicity. A similar periodic pattern in patches of dendrites and in spines has been described and is under detailed characterization in the team. The team already demonstrated that spectrin removal leads to a drastic reduction of dendritic spine number and prevents dendritic spine shape changes during synaptic plasticity. Interestingly, β spectrin is composed of specific domains unfolding upon mechanical forces, as demonstrated for proteins involved in mechano-sensing and mechano-transduction. This led to the hypothesis that the ring-like actin-spectrin network may have a mechano-protective or even a mechano-transduction role during synaptic plasticity.

The PhD student will now investigate the impact of spectrin perturbations (mutants CRISPR/CAS9 KO) on dendritic spine mechanical and functional behavior with the experimental approaches described above.
