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

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

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 ...

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, ...

(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.

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 ...

Researchers at Texas A&M Health have identified a molecular mechanism that increases cholesterol levels inside prostate ...

The discovery that tissues use electricity to expel unhealthy cells is part of a surge of renewed interest in the currents flowing through our bodies. We’re used to thinking of the brain as an ...
