T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on ...

Cell signaling is crucial for cells to communicate and function correctly. Disruptions in these pathways, caused by genetic mutations or environmental factors, can lead to uncontrolled cell growth, ...

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 ...

(MEMPHIS, Tenn. – November 6, 2025) The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme’s “tail” called phosphorylation patterns.

Researchers found that intestinal tuft cells signal to crypt enterochromaffin cells by releasing acetylcholine, triggering serotonin release and activating a gut-to-brain vagal pathway during type 2 ...

Researchers have discovered how mitochondrial stress drives T cell exhaustion and a potential way to restore their ...

A wave of recent neuroscience research has identified specific molecular and cellular mechanisms through which alcohol disrupts signaling between brain cells, offering a sharper picture of how ...
