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, ...

Exemplary Ca2+ signaling microdomains. Cartoon illustration of various microdomains featured in different types of cells, all being artificially integrated in a hypothetical single cell. (1) Cardiac ...

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 ...

(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.

Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate ...

A new preclinical study from Weill Cornell Medicine found that the protein caspase-5 (CASP5), long thought to be a foot ...
