Therapeutic viruses against tumours and metastases

Viruses can overcome cell barriers and transfer information to their host cells. They know how to make their host cell’s infrastructure work for them. This makes them excellent biotechnological tools, which a research group from the Fraunhofer IGB in Stuttgart is using to its advantage. The team is developing a therapeutic virus that not only recognises and fights tumours, but also has the potential to reach metastases.

Microorganisms can increase their host’s ability to adapt to the environment and reproduce – evolutionary biologists are now studying the underlying molecular mechanisms. A research team headed by Dr. Fabian Staubach and Yun Wang from the Institute of Biology I at the University of Freiburg has now studied the relationship of Gluconobacter bacteria and fruit flies. They have found that specific Gluconobacter variants supply the flies with vitamin…

The bacterium Staphylococcus epidermidisis primarily a harmless microbe found on the skin and in the noses of humans. Yet some strains of this species can cause infections – in catheters, artificial joints, heart valves, and in the bloodstream – which are difficult to treat. These bacteria are often resistant to a particularly effective antibiotic, methicillin, and are among the most feared germs in hospitals.

Gene accordions as potential markers for pathogenic properties

Bacteria must react to changes in the environment in order to survive. This is partly done by adapting genetic material, for example by multiplying and shortening individual genome segments. The research group led by Dr. Simon Heilbronner from the Interfaculty Institute of Microbiology and Infection Medicine at the University of Tübingen has shown that these so-called gene accordions are frequently found in the bacterium Staphylococcus aureus.

CRISPR/Cas – genome editing is becoming increasingly popular

The number of publications and patents that involve the CRISPR/Cas system has been increasing exponentially since the technique was first described a few years ago. The increase in funding for projects involving CRISPR/Cas also demonstrates how powerful this new method is. The targeted modification of genomes (also called gene or genome editing) using CRISPR/Cas is extraordinarily accurate and also has the potential to cure hereditary diseases.
