Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them ...
As an embryo develops from a small cluster of stem cells, those once "blank slate" cells begin to take on more specialized roles like brain, liver or muscle cells and organize themselves into ...
UNC researchers discovered how a key step in cell signaling works by showing exactly how G proteins detach from receptors that many common medicines target. Scientists at the University of North ...
Scientists from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), and St. Jude Children's ...
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 ...
