T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the ...

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 ...

A new single‑cell sequencing method is giving researchers a clearer view of how immune cells actually behave—capturing not just what they plan to do, but what they are doing in real time. The platform ...

Deep in the lungs, resident memory B cells stand guard against influenza reinfection—but whether they remain there may depend ...

B cells are white blood cells that form a core part of the body's adaptive immune system, enabling it to recognize specific ...

Supporting cell communication processes is critical for maintaining human performance and long-term health.”— Hunter ...
