Journal ArticleDOI
Cytoplasmic domain heterogeneity and functions of IgG Fc receptors in B lymphocytes.
Sebastian Amigorena,Christian Bonnerot,James R. Drake,Daniel Choquet,Walter Hunziker,Jean-Gérard Guillet,Paul Webster,Catherine Sautes,Ira Mellman,Wolf H. Fridman +9 more
TL;DR: The insertion was not required for Fc gamma RII to modulate surface immunoglobulin-triggered B-cell activation, but did contribute to the formation of caps in response to receptor cross-linking, consistent with suggestions that the lymphocyte but not macrophage form of the receptor can associate with the detergent-insoluble cytoskeleton.
Journal ArticleDOI
Differential activity-dependent regulation of the lateral mobilities of AMPA and NMDA receptors.
Laurent Groc,Martin Heine,Laurent Cognet,Kieran Brickley,F. Anne Stephenson,Brahim Lounis,Daniel Choquet +6 more
TL;DR: Different lateral mobilities for AMPARs and NMDARs are found: changes in neuronal activity modified AMPAR but not NMDar mobility, whereas protein kinase C activation modified both.
Journal ArticleDOI
Surface Mobility of Postsynaptic AMPARs Tunes Synaptic Transmission
Martin Heine,Laurent Groc,Renato Frischknecht,Jean-Claude Béïque,Brahim Lounis,Gavin Rumbaugh,Richard L. Huganir,Laurent Cognet,Daniel Choquet +8 more
TL;DR: It is shown that AMPAR lateral diffusion, observed in both intact hippocampi and cultured neurons, allows fast exchange of desensitized receptors with naïve functional ones within or near the postsynaptic density, which can be explained in part by this fast receptor exchange.
Journal ArticleDOI
The role of receptor diffusion in the organization of the postsynaptic membrane
Daniel Choquet,Antoine Triller +1 more
TL;DR: This work focuses on the physical laws that govern receptor diffusion and stabilization, and how this might reshape how the authors think about the specific regulation of receptor accumulation at synapses.
Journal ArticleDOI
The Dynamic Synapse
Daniel Choquet,Antoine Triller +1 more
TL;DR: Different conceptual and methodological advances that have led to a rethinking of the synapse as an organelle whose function is tightly linked to its dynamic organization are discussed.
