General objective

The team develops several research topics, combining neuroscience, physics and chemistry in order to unravel the dynamics and nanoscale organization of multimolecular receptor complexes and their functional rôle in glutamatergic synaptic transmission in health and disease. Recently, the team has engaged in a major program to analyze and understand the interplay between AMPA type glutamate receptor nanoscale dynamics, synaptic plasticity and memory formation in the healthy and diseased brain. Our latest developments are a major thrust in combining molecular and physiological studies as well as analyzing neurodevelopmental disorders related to synapse dysfunction.

    Co-organization and coactivation of AMPAR, NMDAR, and mGluR

    Nanoscale co-organization and coactivation of AMPAR, NMDAR, and mGluR at excitatory synapses.

    The nanoscale co-organization of neurotransmitter receptors facing presynaptic release sites is a fundamental determinant of their coactivation and of synaptic physiology. At excitatory synapses, how endogenous AMPARs, NMDARs, and mGluRs are co-organized inside the synapse and their respective activation during glutamate release are still unclear. Combining single-molecule super resolution microscopy, electrophysiology, and modeling, we determined the average quantity of each glutamate receptor type, their nanoscale organization, and their respective activation. We observed that NMDARs form a unique cluster mainly at the center of the PSD, while AMPARs segregate in clusters surrounding the NMDARs.mGluR5 presents a different organization and is homogenously dispersed at the synaptic surface. From these results, we build a model predicting the synaptic transmission properties of a unitary synapse, allowing better understanding of synaptic physiology.

    AMPA receptor nanoscale dynamic organization and synaptic plasticities

    Review on “AMPA receptor nanoscale dynamic organization and synaptic plasticities” in Current Opinion in Neurobiology 2020

    The emergence of new imaging techniques and molecular tools has refreshed our understanding of the principles of synaptic transmission and plasticity. Superresolution imaging and biosensors for measuring enzymatic activities in live neurons or neurotransmitter levels in the synaptic cleft are giving us an unprecedented integrated and nanoscale view on synaptic function. Excitatory synapses are now conceptualized as organized in subdomains, enriched with specific scaffolding proteins and glutamate receptors, molecularly organized with respect to the pre-synaptic source of glutamate.

    This new vision of basic synaptic transmission changes our understanding of the molecular modifications which sustain synaptic plasticities. Long-term potentiation can no longer be explained simply by an increase in receptor content at the synapse. We review here the latest data on the role of nanoscale and dynamic organization of AMPA type glutamate receptors on synaptic transmission at both basal state and during short and long-term plasticities.

    A discrete presynaptic vesicle cycle for neuromodulator receptors - Neuron, December 2019

    A major function of GPCRs is to inhibit presynaptic neurotransmitter release, requiring ligand-activated receptors to couple locally to effectors at terminals. The current understanding of how this is achieved is through receptor immobilization on the terminal surface. Here, we show that opioid peptide receptors, GPCRs that mediate highly sensitive presynaptic inhibition, are instead dynamic in axons. Opioid receptors diffuse rapidly throughout the axon surface and internalize after ligand-induced activation specifically at presynaptic terminals. We delineate a parallel regulated endocytic cycle for GPCRs operating at the presynapse, separately from the synaptic vesicle cycle, which clears activated receptors from the surface of terminals and locally reinserts them to maintain the diffusible surface pool. We propose an alternate strategy for achieving local control of presynaptic effectors that, opposite to using receptor immobilization and enforced proximity, is based on lateral mobility of receptors and leverages the inherent allostery of GPCR-effector coupling.

    Access the hidden side of neuronal proteins through the expansion of the genetic code

    Progress in biological imaging is intrinsically linked to advances in labeling methods. The explosion in the development of high-resolution and super-resolution imaging calls for new approaches to label targets with small probes. These should allow to faithfully report the localization of the target within the imaging resolution – typically nowadays a few nanometers - and allow access to any epitope of the target, in the native cellular and tissue environment. We report here the development of a complete labeling and imaging pipeline using genetic code expansion and non-canonical amino acids in neurons that allows to fluorescently label masked epitopes in target transmembrane proteins in live neurons, both in dissociated culture and organotypic brain slices. This allows us to image the differential localization of two AMPA receptor (AMPAR) auxiliary subunits of the transmembrane AMPAR regulatory protein family in complex with their partner with a variety of methods including widefield, confocal, and dSTORM super-resolution microscopy.

    Identification of the molecular mechanisms regulating the intracellular transport of glutamate receptors: a new pathway for controlling synaptic plasticity

    "The modulation of the efficiency of synaptic transmission between neurons is one of the fundamental processes of memory and learning phenomena. This regulation of the strength of synaptic transmission is largely driven by changes in the number of receptors present at the synapse. In this work, the researchers identify a new mechanism for controlling the establishment of receptors at the level of the synapse through the control of their intracellular transport.

    Neurotransmitter receptors, and in particular glutamate receptors, are concentrated in synapses in front of neurotransmitter release sites. However, in the process of their biogenesis, these receptors are synthesized at the level of the endoplasmic reticulum, most of the time several hundred microns from the synapses. They must therefore be transported to the synapses. Our previous work had made possible to visualize for the first time the intracellular transport of AMPA-type glutamate receptors, responsible for the majority of the rapid excitatory transmission between neurons. These receptors are transported rapidly (1-2 microns per second) in vesicles circulating on the microtubules using molecular motors. We observed that, surprisingly, this transport was strongly regulated by neuronal activity.

    In this new work, we have identified the molecular mechanisms responsible for these regulations. The cytosolic C-terminal domain of the AMPAR GluA1 subunit is specifically associated with two proteins, 4.1 N and SAP97. We analyzed how interactions between GluA1 and 4.1N or SAP97 regulate GluA1 transport and its exocytosis under basal conditions and after induction of synaptic plasticity (LTP). Our results identify differential roles of 4.1N and SAP97 in controlling the different phases of transport and membrane integration of GluA1.

    This work opens new perspectives in understanding the molecular mechanisms that control the establishment and maintenance of glutamate receptors at the synapse during synaptic plasticity."

    Daniel Choquet is a member of the 2023 Fulbright France

    Created in 1946 at the proposal of the eponymous US senator, Fulbright is an international academic mobility program of the US government. The aim of the program is to promote educational and cultural exchanges between France and the United States.

    Since its launch, 21,244 students from both countries have benefited from the program:

    • 12,294 French students have gone to the United States of America,
    • 8,950 Americans have come to France.

    Daniel Choquet (director of research at the CNRS, director of IINS, the BIC, the cluster of excellence BRAIN_2030 and team leader at IINS) has just been selected as a laureate of the Fulbright France program. He will be spending a 7 month sabbatical stay in Denver in 2024.

    Why did you apply to the Fulbright France Program?

    “I was getting organized to perform a 7 month sabbatical in Denver in 2022, in the lab of Pr. Mark Dell’Acqua. Given the cost of living in the US, I needed additional funding to support my stay. The Fulbright organization is a very prestigious academic mobility program of the US government and it was thus natural for me to apply, particularly given that there is a specific partnership with our region Nouvelle-Aquitaine.”

    What does it mean to you?

    “Well, it does mean a lot. First, in searching the Fulbright alumni file, I found out that both my parents were fulbrighters in the 50s while they did post-docs in Princeton, my mother with Albert Einstein. Second, I realized when I obtained this fellowship that when you enter a new family, the family of Fulbrighters, beyond the money, you enter a support network all over the US that will be both very interesting and valuable.”

    Will you take this opportunity to discover or develop a research topic?

    “Absolutely, the Department of Pharmacology at the University of Colorado in Denver that I’ll join hosts a large number of high profile neurobiologists that develop orginal cell biology approaches.

    We will join our forces with Mark Dell’Acqua and Matthew Kennedy to develop new methods and approaches to control receptor trafficking and visualization.”

    What do you think this program will bring you, both professionally and personally?

    “In addition to the funding that will help me live there, being a Fulbright fellow in the US is really recognized and will help me develop my network and meet many academics in various disciplines. Fulbright fellow also have a mission to be ambassadors of their country, and I certainly intend to introduce to colleagues to some French cuisine specialties!”

    #IMadteIt: Marie-Lise Jobin, a post-doctoral researcher starting out as an associate professor

    Marie-Lise Jobin is currently a post-doctoral researcher in Daniel Choquet’s "Dynamic organization and function of synapses" team. Interested in the role of the cytoskeleton in the function and structure of dendritic spines, the scientist is supervised by Anna Brachet. Marie-Lise recently obtained a permanent teaching-research position at the Institut National Polytechnique de Bordeaux (Bordeaux INP). Here, she looks back on her career.

    What is your background?
    "I studied biology and structural biochemistry at the University of Bordeaux. During my Master’s and PhD, I worked in many different laboratories. First, I spent three months working at the University of Guelph in Ontario, Canada. Then, for my PhD, I joined the Institute of Chemistry and Biology of Membranes and Nano-objects (CBMN) in Pessac. On completion of my studies, I spent a year as a post-doctoral fellow at the Nutrition and Integrative Neurobiology Laboratory (Nutrineuro) in Bordeaux. I then spent over three years at the University of Würzburg in Bavaria, Germany. And for the last four years I’ve been at IINS. My post-doctoral adventure will finally come to an end at the end in September 2023, and I’ll be taking up a position as an associate professor in September!"

    Why did you join IINS?
    "Generally speaking, I’ve always been interested in biomolecular interactions involving cell membranes. I first worked on synthetic membrane models. However, I’ve always wanted to study more physiological systems. So the neuroscience field allows me to work with systems closer to physiology, and to use my highly interdisciplinary skills. [...] Anna Brachet’s field of research on the role of cytoskeletal proteins, in particular spectrins, and their partners, in the regulation, function and mechano-transduction of dendritic spines fit perfectly my research interests. Moreover, IINS is considered one of the most recognized institutes in the field of neuroscience. Above all, IINS is part of a synergistic system, with close relations to the Bordeaux Imaging Center (BIC). It was a unique opportunity to develop my skills in cutting-edge microscopy techniques and gain access to considerable knowledge in this field!"

    Can you tell us about your research?
    "I’m trying to understand the role of cytoskeletal proteins, beta spectrins, in neurons, and more specifically in dendritic spines, which are the seat of neuronal transmission. My results showed that beta spectrins are co-organised on a nanoscopic scale in dendritic spines and are particularly important for the stability of these structures. Their membrane or cytoskeleton partners are all the more important in maintaining and stabilising these spectrins under the membrane and influence their nano-organisation."

    As a woman in science, what difficulties have you encountered?
    "My biggest difficulty has always been a lack of self-confidence. But throughout my career I’ve been lucky enough to meet scientists, men and women who have had faith in me, and who have always supported and encouraged me along the way."

    Why do women need to be more recognised in the scientific community?
    "It seems quite logical to me that gender diversity, or diversity of any kind, leads to better, more creative and innovative science. I can see that things are changing, slowly but surely, in the right direction, and I’m optimistic for the future!"

    Any advice for young researcher?
    "I’m proud to have got where I am, to have succeeded in obtaining a permanent position in academia, and to have stayed the course despite many years of not knowing what would happen and never giving up. You have to persevere. It’s often the fear of failing that stops us from moving forward, so don’t hesitate, dare to take the plunge and, above all, trust yourself."
