Journal ArticleDOI
Dynamic multiple-target tracing to probe spatiotemporal cartography of cell membranes.
Arnauld Sergé,Nicolas Bertaux,Nicolas Bertaux,Nicolas Bertaux,Hervé Rigneault,Hervé Rigneault,Didier Marguet,Didier Marguet +7 more
TL;DR: An analytical single-particle tracking method and tool, multiple-target tracing (MTT), that takes advantage of the high spatial resolution provided by single-fluorophore sensitivity to generate dynamic maps at high densities of tracked particles, thereby providing global representation of molecular dynamics in cell membranes.
Journal ArticleDOI
Quantitative nanoscale imaging of orientational order in biological filaments by polarized superresolution microscopy
Cesar Augusto Valades Cruz,Haitham A. Shaban,Alla Kress,Nicolas Bertaux,Serge Monneret,Manos Mavrakis,Julien Savatier,Sophie Brasselet +7 more
TL;DR: It is demonstrated that quantitative single-molecule polarized detection in biological filament assemblies allows not only to correct for the rotational flexibility of the label but also to image orientational order of filaments at the nanoscale using superresolution capabilities.
Journal ArticleDOI
Minimum description length synthetic aperture radar image segmentation
TL;DR: This approach leads to a global MDL criterion without an undetermined parameter since no other regularization term than the stochastic complexity of the polygonal grid is necessary and noise parameters can be estimated with maximum likelihood-like approaches.
Journal ArticleDOI
Barcoding T cell calcium response diversity with methods for automated and accurate analysis of cell signals (MAAACS).
Audrey Salles,Audrey Salles,Audrey Salles,Cyrille Billaudeau,Cyrille Billaudeau,Cyrille Billaudeau,Arnauld Sergé,Arnauld Sergé,Arnauld Sergé,Anne-Marie Bernard,Anne-Marie Bernard,Anne-Marie Bernard,Marie-Claire Phelipot,Marie-Claire Phelipot,Marie-Claire Phelipot,Nicolas Bertaux,Nicolas Bertaux,Mathieu Fallet,Mathieu Fallet,Mathieu Fallet,Pierre Grenot,Pierre Grenot,Pierre Grenot,Didier Marguet,Didier Marguet,Didier Marguet,Hai-Tao He,Hai-Tao He,Hai-Tao He,Yannick Hamon,Yannick Hamon,Yannick Hamon +31 more
TL;DR: This method allowed us to unravel the heterogeneity in shape and intensity of the calcium response in T cell populations and especially in naive T cells, which display intracellular calcium oscillations upon stimulation by antigen presenting cells.
Book ChapterDOI
Probing the plasma membrane organization in living cells by spot variation fluorescence correlation spectroscopy.
Cyrille Billaudeau,Sébastien Mailfert,Sébastien Mailfert,Sébastien Mailfert,Tomasz Trombik,Tomasz Trombik,Tomasz Trombik,Nicolas Bertaux,Nicolas Bertaux,Vincent Rouger,Vincent Rouger,Vincent Rouger,Yannick Hamon,Yannick Hamon,Yannick Hamon,Hai-Tao He,Hai-Tao He,Hai-Tao He,Didier Marguet,Didier Marguet,Didier Marguet +20 more
TL;DR: A method, namely spot variation FCS (svFCS), to decipher the dynamics of the plasma membrane organization is described, based on questioning the relationship between the diffusion time τ(d) and the squared waist of observation w(2).
