Mailfert S, Djendli M, Fabre R, Marguet D, Bertaux N
Biophys J . 2025 Feb; PMID: 40012204
Single-molecule localization microscopy (SMLM) has revolutionized the understanding of cellular organization by reconstructing informative images with quantifiable spatial distributions of molecules far beyond the optical diffraction limit. Much effort has...

Mailfert S, Wojtowicz K, Brustlein S, Blaszczak E, Bertaux N, Lukaszewicz M, et al.
J Vis Exp . 2020 Nov; (165). PMID: 33252108
Dynamic biological processes in living cells, including those associated with plasma membrane organization, occur on various spatial and temporal scales, ranging from nanometers to micrometers and microseconds to minutes, respectively....

Mailfert S, Touvier J, Benyoussef L, Fabre R, Rabaoui A, Blache M, et al.
Biophys J . 2018 Jul; 115(3):565-576. PMID: 30029772
Single-molecule localization microscopy (SMLM) enables the production of high-resolution images by imaging spatially isolated fluorescent particles. Although challenging, the result of SMLM analysis lists the position of individual molecules, leading...

Blouin C, Hamon Y, Gonnord P, Boularan C, Kagan J, Viaris de Lesegno C, et al.
Cell . 2016 Aug; 166(4):920-934. PMID: 27499022
Understanding how membrane nanoscale organization controls transmembrane receptors signaling activity remains a challenge. We studied interferon-γ receptor (IFN-γR) signaling in fibroblasts from homozygous patients with a T168N mutation in IFNGR2....

Vannier N, Goudail F, Plassart C, Boffety M, Feneyrou P, Leviandier L, et al.
Appl Opt . 2016 May; 55(11):2881-91. PMID: 27139850
We address the detection of manufactured objects in different types of environments with active polarimetric imaging. Using an original, fully adaptive imager, we compare several imaging modes having different numbers...

Valades Cruz C, Shaban H, Kress A, Bertaux N, Monneret S, Mavrakis M, et al.
Proc Natl Acad Sci U S A . 2016 Feb; 113(7):E820-8. PMID: 26831082
Essential cellular functions as diverse as genome maintenance and tissue morphogenesis rely on the dynamic organization of filamentous assemblies. For example, the precise structural organization of DNA filaments has profound...

Vannier N, Goudail F, Plassart C, Boffety M, Feneyrou P, Leviandier L, et al.
Appl Opt . 2015 Sep; 54(25):7622-31. PMID: 26368885
We designed and built an active polarimetric imager with laser illumination at 1.5 μm wavelength for adaptive polarimetric contrast optimization. It can generate and analyze any polarization state on the...

Salles A, Billaudeau C, Serge A, Bernard A, Phelipot M, Bertaux N, et al.
PLoS Comput Biol . 2013 Oct; 9(9):e1003245. PMID: 24086124
We introduce a series of experimental procedures enabling sensitive calcium monitoring in T cell populations by confocal video-microscopy. Tracking and post-acquisition analysis was performed using Methods for Automated and Accurate...

Anna G, Bertaux N, Galland F, Goudail F, Dolfi D
Opt Lett . 2013 Feb; 37(16):3321-3. PMID: 23381244
We present a method for automatic target detection based on the iterative interplay between an active polarimetric imager with adaptive capabilities and a snake-based image segmentation algorithm. It successfully addresses...

Billaudeau C, Mailfert S, Trombik T, Bertaux N, Rouger V, Hamon Y, et al.
Methods Enzymol . 2013 Jan; 519:277-302. PMID: 23280115
While intrinsic Brownian agitation within a lipid bilayer does homogenize the molecular distribution, the extremely diverse composition of the plasma membrane, in contrast, favors the development of inhomogeneity due to...
