Much like our fight-or-flight response, our cells also have a stress autopilot mode. An oxygen dropoff, overheating, or an invading toxin can trigger the cellular stress response – a cascade of molecular changes that are ...

Protein aggregates that form after a cell is exposed to high, non-lethal temperatures appear to be part of an organized response to stress, and not the accumulation of damaged proteins en route to destruction. Reporting in ...
