Cell walls are a crucial structure of plant life, protecting cells from damage, giving plants shape, and containing energy-rich nutrients. And yet the process of how the walls begin to form remains ...

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. Subscribe to our newsletter for the latest ...

Mitochondria are specialized structures within cells that are primarily responsible for energy production but that also play a key role in how cells respond and adapt to stress. When their function ...

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 ...

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 ...
