A toolbox for creating new drugs

ETH microbiologists led by Markus Künzler have discovered a remarkable enzyme in a fungus. They now want to use it to develop new drugs.

Probing the pores in membrane vesicles

Ion channels in the membrane vesicles that mediate intracellular protein transport play a crucial role in cell physiology. A method developed by an Ludwig-Maximilians-Universitaet (LMU) in Munich team now allows them to be ...

Study predicts heart cells' response to dwindling oxygen

Time is of the essence when treating a patient undergoing a heart attack. Cardiac surgeons attempt to quickly stabilize the heart by applying reperfusion, a technique that restores oxygen to the heart by opening up blocked ...

Researchers report on cell-permeable nanobodies

Scientists at the Technische Universität Darmstadt, Ludwig Maximilians University (LMU) Munich and the Leibniz Institute for Molecular Pharmacology (FMP) have managed to introduce tiny antibodies into living cells. The researchers ...

Biosensors light up cellular signaling processes

Researchers at the University of California, Riverside have converted a naturally occurring fluorescent protein from corals into a biosensor that can be used to monitor the cellular thioredoxin (Trx) system, which is a promising ...

On the way to a biological alternative

The research team of Prof. Dr. Oliver Einsle at the University of Freiburg's Institute of Biochemistry has long been exploring the functioning of nitrogenase. Now the group is introducing the first three-dimensional structural ...

Treating fungal cornea infection with synthetic molecules

A*STAR researchers have created synthetic molecules to treat fungal keratitis – an infection of the cornea that causes visual disability. The new molecules are a first step toward developing effective drugs to combat this ...
