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 ...

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, ...

Every multicellular organism, from tiny worms to humans, elephants, and whales, needs a way for their cells to connect with each other to form tissues, organs, and organize their overall body plan.

(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.

Microtubules perform an active role in communication within the cell by transmitting received signals to the cell's functional units. Researchers at the Paul Scherrer Institute PSI and the Department ...

Cells use various signaling molecules to regulate the nervous, immune, and vascular systems. Among these, nitric oxide (NO) and ammonia (NH₃) play important roles, but their chemical instability and ...

New molecular insights into the link between hepatocellular carcinoma and intratumoral fibrosis could lead to better ...

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 ...

Researchers at the Cancer Research Institute and the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, have uncovered a critical mechanism that enables gastric cancer to spread to ...
