Dying cells protect their neighbors to maintain tissue integrity

To enable tissue renewal, human tissues constantly eliminate millions of cells, without jeopardizing tissue integrity, form and connectivity. The mechanisms involved in maintaining this integrity remain unknown. Scientists ...

Newly discovered lipid prevents cell death

Programmed cell death is an important tool that an organism uses to keep itself healthy. When a cell does not function as it should, various stress reactions are activated. The goal of these reactions is to restore the original ...

Deadly combination: New direct trigger for cell death discovered

Scientists led by Professor Ana J. Garcia-Saez at the CECAD Cluster of Excellence for Aging Research at the University of Cologne have shown that apoptosis, the programmed cell death, involves a direct physical interplay ...

A protein provides stress relief for cells

German researchers have shown a new mechanism via which cells defend themselves against stress. Dr. Kathrin Thedieck and Birgit Holzwarth from the Institute of Biology III and the Cluster of Excellence BIOSS Centre for Biological ...

Radical new treatment system lights up cancer therapy

One approach to treating cancer is photodynamic therapy using photo-uncaging systems, in which light is used to activate a cancer-fighting agent in situ at the tumor. However, suitable agents must be stable under visible ...

New, more sensitive sensor for evaluating drug safety

A new technique for evaluating drug safety can detect stress on cells at earlier stages than conventional methods, which mostly rely on detecting cell death. The new method uses a fluorescent sensor that is turned on in a ...
