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 ...

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 ...

A new study reveals evidence of electrical signaling and coordinated behavior in choanoflagellates, the closest living relatives of animals. This elaborate example of cell communication offers key ...
