RSS feedVisualization of the Natural Killer Cell Immune Synapse by Super-Resolution Nanoscopy
Natural killer (NK) cells are innate immune effectors that recognize and kill virally infected and tumorigenic cells. Central to their effector function is the formation of an immunological synapse…Read articleSharp Live Images from the Mouse Brain
To explore the most intricate structures of the brain in order to decipher how it functions – Stefan Hell’s team of researchers at the Max Planck Institute for Biophysical Chemistry in Göttingen has…Read articleDual Channel STED Nanoscopy of Lytic Granules on Actin Filaments in Natural Killer Cells
Natural killer (NK) cells are innate immune effectors that eliminate diseased and tumorigenic targets through the directed secretion of specialized secretory lysosomes, termed lytic granules. This…Read articleLive-cell Imaging Techniques
The understanding of complex and/or fast cellular dynamics is an important step for exploring biological processes. Therefore, today’s life science research is increasingly focusing on dynamic…Read articleVideos on STED Microscopy and its Inventor Stefan Hell
Here we present an collection of videos telling the story of the invention of nanometer-scale microscopy by Stefan Hell and explaining the basic principle of STED microscopy.Read articleSubcellular Localization of AKT and Tubulin using Super-Resolution Microscopy
Stimulated Emission Depletion microscopy, or STED nanoscopy, is a technique that uses the non-linear de-excitation of fluorescent dyes to overcome the resolution limit imposed by diffraction…Read articleTwo-color STED Microscopy of Living Synapses using a Single Laser-beam Pair
The advent of superresolution microscopy has opened up new research opportunities into dynamic processes at the nanoscale inside living biological specimens. This is particularly true for synapses,…Read articleModern Fluorescent Proteins and their Biological Applications

Neurobiology, the science of nerves and the brain, has mainly been driven forward in the last 200 years by microscopic investigations. The structures of cellular and subcellular structures,…Read articleNatural Killer Cell Lytic Granule Secretion Occurs through a Pervasive Actin Network at the Immune Synapse
Accumulation of filamentous actin (F-actin) at the immunological synapse (IS) is a prerequisite for the cytotoxic function of natural killer (NK) cells. Subsequent to reorganization of the actin…Read articleSTED Nanoscopy of Actin Dynamics in Synapses deep inside Living Brain Slices
It is difficult to investigate the mechanisms that mediate long-term changes in synapse function because synapses are small and deeply embedded inside brain tissue. Although recent fluorescence…Read articleNanoscopy in a Living Multicellular Organism Expressing GFP
We report superresolution fluorescence microscopy in an intact living organism, namely Caenorhabditis elegans nematodes expressing green fluorescent protein (GFP)-fusion proteins. We also…Read articleRestless Receptors
Synapses are the switch-points in our brain for information transmission, learning and memory. News studies and developments of imaging techniques have provided new insights into the dynamics of…Read articleThe Missing Link to the Nanocosm of Life
Fully understanding the functionality and complexity of the human central nervous system remains one of the major open questions in modern science. Stimulated emission depletion microscopy (STED) can…Read article
