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 ...

Many types of cancer are caused by gene mutations in the signalling pathways that control cell growth, such as the hedgehog signalling pathway. A new study from the Karolinska Institutet, published in ...

Our body receives and processes a vast number of signals. Chemical signals serve as guidance cues and ensure, for example, that immune cells arrive exactly where they are needed. Many vital processes ...

Unlike accidental cell death, some cells can actively decide to die through a controlled process. This is called programmed ...

Researchers from the Keck School of Medicine of USC have developed a new type of chimeric antigen receptor (CAR) T cell that elicits a more controlled immune response to cancer in mice—effectively ...

Illustration of small molecule modulation of β-arrestins and GPCR signaling pathways based on concepts developed by the Lefkowitz Laboratory, Duke University. To function normally, nearly every cell ...

Peptide research has expanded dramatically as investigators continue to explore short amino acid chains that participate in intricate regulatory networks across biological system. Among these ...
