Signal transduction is the fundamental process by which cells convert external cues into tailored intracellular responses. Through a cascade of molecular events—beginning at the cell membrane with the ...

Bacterial chemotaxis is a sophisticated behavioural process that enables microorganisms to navigate toward favourable environments by detecting subtle differences in chemical gradients. At the heart ...

cases an external molecule dramatically affects cellular function. Our goal in studying any of these processes is the same: a molecule-by-molecule accounting of information transfer in biological ...

Designated areas (white circles) were irradiated with blue light at specific frequencies (indicated in the top left of each panel) to examine chemotactic aggregation. A research team led by Dr.

Researchers at Ben-Gurion University of the Negev have identified a protein that plays a central role in enabling aggressive ...

The design of new calcium channels, built bottom-up from scratch, was reported last week in Nature. "Biochemists have been studying ion channels for decades and debating about how they work for almost ...

Researchers at the Department of Pharmacology and Toxicology at the University Medical Center Göttingen (UMG) have discovered a key genetic regulatory mechanism that becomes disrupted in heart failure ...
