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 ...
Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or ...
Researchers at the University of Arizona have uncovered a previously unknown population of circulating immune cells that play a critical role in fibrosis, the buildup of scar tissue that can lead to ...
