As an embryo develops from a small cluster of stem cells, those once "blank slate" cells begin to take on more specialized ...

An international research team led by Dr. Lucia Torres Fernández from the working groups of Professor Dr. Julie George and ...

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, ...

Donald Trump says he will campaign in 35 battleground congressional districts during the final weeks of the US midterm ...

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 ...

The structural and functional characteristics of mitochondria shape their role as signaling organelles, with far-reaching effects regarding immune responses, inflammatory processes, and diseases. A ...

Researchers have investigated the role of a certain enzyme in regulating energy in muscle and exercise performance for decades, but a new study by Virginia Tech scientists has identified more ...

Calcium is widely known for its role in maintaining strong bones and teeth, but it is also one of the body's most important cellular messengers. Calcium signals help regulate muscle contraction, ...

Acting as armor, a scaffold and a communication platform in one, our cells' plasma membrane lies at the heart of many crucial cellular processes. Traditionally, it has been thought to function through ...

Beyond the potential clinical application, the study sheds new light on T cell biology and how cells are directed towards specific lineages.
