Blood vessel cells keep fixed signaling roles for weeks, reshaping view of capillary communication

The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood ...

By making key signaling molecules called β-arrestins into druggable targets, scientists crack long-standing challenge

To function normally, nearly every cell in the human body relies on G-protein-coupled receptors (GPCRs) to receive and send ...

ROS-producing enzymes guide plant cell division and tissue patterning, gene-editing study shows

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling.
