Abstracts of the 7th European Super-Resolution User-Club Meeting
The 7th Super-Resolution User Club Meeting was held in collaboration with Prof Pavel Hozák , at the Institute of Molecular Genetics of the ASCR in Prague. Keeping the event close to science is one of…Read article
Super-Resolution Optical Microscopy of Lipid Plasma Membrane Dynamics
Plasma membrane dynamics are an important ruler of cellular activity, particularly through the interaction and diffusion dynamics of membrane-embedded proteins and lipids. FCS (fluorescence…Read article
Practical Guide for Excellent GSDIM Super-Resolution Images
Do you know that most protists and bacteria lack in one feature that each of our body cell has? Our cells are touch and communicate with one another. They send and receive a variety of signals that…Read article
Initiation of Lamellipodia and Ruffles Involves Cooperation Between mDia1 and the Arp2/3 Complex
Protrusion of lamellipodia and ruffles requires polymerization of branched actin filaments by the Arp2/3 complex. Although regulation of Arp2/3 complex activity has been extensively investigated, the…Read article
Visualizing Tropoelastin in a Long-Term Human Elastic Fibre Cell Culture Model
Elastin is an essential protein found in a variety of tissues where resilience and flexibility are needed, such as the skin and the heart. When aiming to engineer suitable implants, elastic fibres are…Read article
Botulinum Neurotoxin Type-A Enters a Non-Recycling Pool of Synaptic Vesicles
Neuronal communication relies on synaptic vesicles undergoing regulated exocytosis and recycling for multiple rounds of fusion. Whether all synaptic vesicles have identical protein content has been…Read article
Abstracts of the 6th European Super-Resolution User-Club Meeting
The 6th European Super-Resolution User Club Meeting was held in collaboration with Dr. Timo Zimmermann, CRG, and Dr. Pablo Loza-Alvarez, ICFO, Barcelona. According to the founding principle of the…Read article
Measuring the 3D STED-PSF with a new Type of Fluorescent Beads
A new type of fluorescent bead is presented by GATTAquant. These beads, called GATTA-Beads, are characterized by a small diameter (23 nm), high intensity and size uniformity. In combination with…Read article
Mirror-Enhanced Super-Resolution Microscopy
Axial excitation confinement beyond the diffraction limit is crucial to the development of next-generation, super-resolution microscopy. STimulated Emission Depletion (STED) nanoscopy offers lateral…Read article
The Actin Cytoskeleton Modulates the Activation of iNKT Cells by Segregating CD1d Nanoclusters on Antigen-Presenting Cells
The ability of invariant natural killer T (iNKT) cells to recognize endogenous antigens represents a distinct immune recognition strategy, which underscores the constitutive memory phenotype of iNKT…Read article
Translation Microscopy (TRAM) for Super-Resolution Imaging
Super-resolution microscopy is transforming our understanding of biology but accessibility is limited by its technical complexity, high costs and the requirement for bespoke sample preparation. We…Read article
Two-Photon Excitation STED Microscopy with Time-Gated Detection
We report on a novel two-photon excitation stimulated emission depletion (2PE-STED) microscope based on time-gated detection. The time-gated detection allows for the effective silencing of the…Read article
Quantifying the Resolution of a Leica SR GSD 3D Localization Microscopy System with 2D and 3D Nanorulers
DNA origami based nanorulers produced by GATTAquant are common standards to test the achievable spatial resolution of super-resolution microscopes. Recently the nanorulers were used to test the…Read article
Super-Resolution Mapping of Neuronal Circuitry With an Index-Optimized Clearing Agent
Super-resolution imaging deep inside tissues has been challenging, as it is extremely sensitive to light scattering and spherical aberrations. Here, we report an optimized optical clearing agent for…Read article
4Pi-RESOLFT Nanoscopy
Here we apply the 4Pi scheme to RESOLFT nanoscopy using two-photon absorption for the on-switching of fluorescent proteins. We show that in this combination, the lobes are so low that low-light level,…Read article
