For the first time ever, expansion microscopy allows the imaging of even the finest details of cell membranes. This offers new insights into bacterial and viral infection processes
04-Dec-2020
Expansion microscopy (ExM) enables the imaging of cells and their components with a spatial resolution far below 200 nanometres. For this purpose, the proteins of the sample under investigation are cross-linked into a swellable polymer. Once the interactions between the molecules have been ...
Smallest cell structures can now be imaged even better
10-Jul-2020
High-resolution microscopy makes it theoretically possible to image cell structures with a resolution of a few nanometres. However, this has not yet been possible in practice. The reason for this is that antibodies carrying a fluorescent dye are usually used to mark the cell structures. The dye ...
New details are known about an important cell structure
06-Jul-2020
For the first time, two Würzburg research groups have been able to map the synaptonemal complex three-dimensionally with a resolution of 20 to 30 nanometres. The synaptonemal complex is a ladder-like cell structure that plays a major role in the development of egg and sperm cells in humans and ...
A comprehensive systems biological analysis of the herpes virus genome has caused some surprises
30-Apr-2020
The genome of the herpes simplex virus 1 was decoded using new methods. Hundreds of previously unknown gene products were found. The virus causes lip herpes, but can also be life-threatening. Until now, scientists had assumed that there are about 80 so-called open reading frames (ORFs) in the ...

Vaccinia viruses serve as a vaccine against human smallpox and as the basis of new cancer therapies. Two studies now provide fascinating insights into their unusual propagation strategy at the atomic level. For viruses to multiply, they usually need the support of the cells they infect. In many ...

Researchers at the University of Würzburg and the Spanish Cancer Research Centre have gained new insights into the pathogen that causes tuberculosis. The work published in Nature provides the basis for a new approach in antibiotic therapy. Tuberculosis is a highly contagious infectious disease ...

Artemisinin is derived from the leaves and flowers of the annual mugwort (Artemisia annua) and has been used in traditional Chinese medicine for centuries. The effectiveness was investigated by the Chinese researcher Tu Youyou. Her research was 2015 rewarded with the Nobel Prize. Artemisinin and ...

Does expansion microscopy deliver true-to-life images of cellular structures? That was not sure yet. A new publication shows for the first time that the method actually works reliably. Immersing deeper and deeper into cells with the microscope. Imaging the nucleus and other structures more and ...

Physicists from Dresden and Würzburg have developed a novel method for optical microscopy. Using biological motors and single quantum dots, they acquire ultra-high-resolution images. The resolution of conventional optical microscopy is limited by the fundamental physical principle of diffraction ...
Technological developments allow new insights
23-Oct-2017
Using a revolutionary live-cell microscopy technique, an international team of scientist has observed for the first time individual receptors for hormones and widely used drugs at work in intact cells. G protein-coupled receptors (GPCRs) are among the "hottest” targets for the therapy of diseases ...
