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 ...

A cluster of recent studies has sharpened the scientific picture of how T cells switch on, tracking the molecular signals ...

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, ...

A wave of recent neuroscience research has identified specific molecular and cellular mechanisms through which alcohol disrupts signaling between brain cells, offering a sharper picture of how ...

Tooth loss and bone degeneration are problems that modern medicine still struggles to fix. Data from the National Bone Health Policy Institute shows that 10 million Americans over the age of 50 have ...
