The surprising finding, by a Swiss research team led by investigators from the Lausanne Branch of the international Ludwig Institute for Cancer Research (LICR), showed that c-myc functions in the immune system’s ‘memory’ of previous infections.
“Very little is known about the signalling pathways that actually control IL-15-dependent homeostasis,” explains LICR’s Dr. H. Robson MacDonald, the senior author of the study. “By analyzing genetically engineered mouse models with reduced c-myc, reduced IL-15 or absent IL-15, we discovered that it’s actually c-myc, which is known primarily as an oncogene, that acts downstream of the IL-15 signaling pathway to regulate T memory cell homeostasis.”
According to Dr. MacDonald, the study is basic research that may have implications for therapies of the future. “Understanding how immune memory works might allow us to improve therapeutic vaccines against, say, malaria or cancer. The unexpected finding is that this study is also a cautionary tale. Before we design new therapies that inactivate a gene product, which is an approach being considered for c-myc in cancer, we need to be very sure that we are not going to be also destroying a vital role in a normal process such as the body’s immune system.”

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
