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, ...

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

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

We owe a lot to tissue resident memory T cells (T RM). These specialized immune cells are among the body's first responders to disease. Rather than coursing through the bloodstream-as many T cells ...

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