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 ...

New insights into the structure of a killer protein

Researchers at Ruhr-Universität Bochum and the University of Tübingen have gained new insights into the structure of the killer protein Bax. The protein induces programmed cell death, the method by which the body disposes ...

Newly discovered enzyme is 'firing pin' for plant immunity

Just like humans, plants have an immune system that helps them fight off infections. Plant immunity has some important differences: they don't make antibodies and can't fight off the same bug more quickly months or years ...

The mechanisms of plant aging

European researchers investigated the molecular mechanisms that drive stress-related responses that cause aging and death in plants. The goal is to generate resilient crop varieties.

Cancer-causing virus masters cell's replication, immortality

Viruses are notorious for taking over their host's operations and using them to their own advantage. But few human viruses make themselves quite as cozy as the Epstein-Barr virus, which can be found in an estimated nine out ...

Programmed cell death

Programmed cell-death (or PCD) is death of a cell in any form, mediated by an intracellular program. In contrast to necrosis, which is a form of cell-death that results from acute tissue injury and provokes an inflammatory response, PCD is carried out in a regulated process which generally confers advantage during an organism's life-cycle. PCD serves fundamental functions during both plant and metazoa (multicellular animals) tissue development.
