A formin-nucleated actin aster concentrates cell wall hydrolases for cell fusion in fission yeast
Thierry Laroche, Arne Seitz, Omaya Pierre Dudin, Raphaël Groux
Cell-cell fusion is essential for fertilization. For fusion of walled cells, the cell wall must be degraded at a precise location but maintained in surrounding regions to protect against lysis. In fission yeast cells, the formin Fus1, which nucleates linea ...
Rockefeller Univ Press2015Ultra-soft cantilevers and 3-D micro-patterned substrates for contractile bundle tension measurement in living cells
Jean-Jacques Meister, Niccolo Piacentini, Chiara Gabella, Benoît Vianay
Actin-myosin microfilament bundles or stress-fibers are the principal tension-generating structures in the cell. Their mechanical properties are critical for cell shape, motion, and interaction with other cells and extracellular matrix, but were so far dif ...
Royal Society of Chemistry2014High throughput 3D super-resolution microscopy reveals Caulobacter crescentus in vivo Z-ring organization
Suliana Manley, Karin Lederballe Meibom, Seamus John Holden, Thomas Pengo
We created a high-throughput modality of photoactivated localization microscopy (PALM) that enables automated 3D PALM imaging of hundreds of synchronized bacteria during all stages of the cell cycle. We used high-throughput PALM to investigate the nanoscal ...
Natl Acad Sciences2014Cell-type-specific 2 adrenergic receptor clusters identified using photo-activated localization microscopy are not lipid raft related, but depend on actin cytoskeleton integrity
Aleksandra Radenovic, Paolo Annibale, Marco Scarselli
Recent developments in the field of optical super-resolution techniques allow both a 10-fold increase in resolution as well as an increased ability to quantify the number of labeled molecules visualized in the fluorescence measurement. By using photoactiva ...
2012Mechanisms of LRRK2-Mediated Neurodegeneration
Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene represent the most common cause of familial Parkinson's disease (PD), whereas common variation at the LRRK2 locus is associated with an increased risk of idiopathic PD. Considerable progress has be ...
Current Science Inc., Springer2012Statistical analysis of the current-sharing temperature evolution in Nb3Sn cable-in-conduit-conductors for ITER
Pierluigi Bruzzone, Davide Uglietti, Boris Stepanov, Rainer Wesche
During the test of ITER conductors at nominal conditions, a degradation of the current sharing temperature has been observed after electromagnetic cyclic loading. Rather than focusing on the microscopic phenomena at the origin of the degradation, the degra ...
IEEE-Inst Electrical Electronics Engineers Inc2012A Role for Septins in the Interaction between the Listeria monocytogenes Invasion Protein InlB and the Met Receptor
Septins are conserved GTPases that form filaments and are required for cell division. During interphase, septin filaments associate with cellular membrane and cytoskeleton networks, yet the functional significance of these associations have, to our knowled ...
Elsevier2011Force Transmission in Migrating Cells
Ability to migrate is a fundamental property of all animal cells. Cell migration underlies such important physiological and pathological processes as embryonic development, immune response, tissue regeneration and cancer metastasis. As cell migration invol ...
EPFL2011Regulation of cortical contractility and spindle positioning by the protein phosphatase 6 PPH-6 in one-cell stage C. elegans embryos
Modulation of the microtubule and the actin cytoskeleton is crucial for proper cell division. Protein phosphorylation is known to be an important regulatory mechanism modulating these cytoskeletal networks. By contrast, there is a relative paucity of infor ...
2010The Cas A-Like Snr 1E 0102.2-7219 In The Small Magellanic Cloud: An Asymmetric Bipolar Explosion
We have used the Wide Field Spectrograph on the 2.3 m telescope at Siding Spring Observatory to map the [O III] lambda 5007 dynamics of the young oxygen-rich supernova remnant 1E 0102.2-7219 in the Small Magellanic Cloud. From the resultant data cube, we h ...
