Signaling is fundamental to how cells sense and respond to their environment—but in immune cells, those signals must be ...

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, ...

Mitochondrial calcium signalling plays a fundamental role in cellular homeostasis by modulating energy production and activating key metabolic enzymes. Calcium ions (Ca2+) are dynamically exchanged ...

(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.

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 ...

Scientists led by Sergey Troyanovsky, Ph.D., professor of Dermatology and of Cell and Developmental Biology, have uncovered new intracellular mechanisms promoting cell-cell adhesion, a process ...

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 ...
