Cancer can often evade the immune system by sending signals that fool it into thinking that the cancer cells are normal, healthy cells and that it should ignore them. Earlier this year, we reported on an approach to treating cancer in which the immune system can be taught to detect cancer by seeing past the cancer cell’s attempts to hide.

One of these attempts involves a signaling pathway that sends a “don’t Eat Me” signal to the immune system. Now, researchers at the Stanford University School of Medicine have discovered a second biological pathway that signals the immune system not to engulf and consume cancer cells.
