Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them navigate toward food sources. In multicellular organisms, growth factors, ...

A team led by Stanford biologist Bo Wang and lead author Chew Chai has identified a previously unknown type of immune cell in ...

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 ...

Researchers at Rice University developed a cytokine factory patch that continuously releases healing proteins into wounds, ...

Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize ...

Purinergic signaling, mediated by extracellular nucleotides such as ATP and UTP, has been increasingly studied for its role in regulating cellular communication. A new review by researchers in ...

The distinct aging rates of neural progenitor cells and Wnt signaling dictate mammalian cortical layer proportions.

The research details how neurons and glial cells utilize leucine-derived acetyl-coenzyme A (AcCoA) rather than canonical ...
