Redox biology investigates how reversible oxidation–reduction (redox) reactions regulate fundamental cellular processes. Central to this field is the role of reactive oxygen species (ROS), such as ...

In response to stimulation, young cells produce H2O2 and transduce signals through a PRDX2-based redox relay, thereby activating RRC. However, in senescent cells, the increase in PRDX2 hyperoxidation ...
