Cell-communication molecules called kinases play a key role in the growth and spread of many cancers. But exactly which ...

A Cell perspective argues that neurodegeneration can emerge from disrupted communication between neural and immune networks, ...

Signaling is fundamental to how cells sense and respond to their environment—but in immune cells, those signals must be precisely amplified to mount an effective defense against invasive threats. New ...

The design of new calcium channels, built bottom-up from scratch, was reported last week in Nature. "Biochemists have been studying ion channels for decades and debating about how they work for almost ...

A molecular pathway known for controlling cell shape and movement also helps regulate the rhythm by which the vertebrate body ...

The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme's "tail" called phosphorylation patterns. Scientists at St. Jude Children's ...

The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have ...

Gliomas are malignant brain tumors that originate from glial cells, which do not produce electrical impulses like neurons but ...
