(PhysOrg.com) -- A recently identified immune cell that directs other cells to fight infection plays a critical role in regulating the immune system in both health and disease. Researchers from the University of Pennsylvania School of Medicine have discovered how a stimulatory molecule and a protein found on the membrane of another immune cell make T helper 17 cells multi-taskers of sorts.
