Who defines the traffice rules in the immune system? Immune cells patrol the blood vessels. Only in the event of inflammation or infection of the tissue, they receive the necessary green light to suddenly leave the vessels. Here, the cells cross the field – attracted by signals emitted by the damaged tissue. Tim Lämmermann, research group leader at the MPI of Immunobiology and Epigenetics in Freiburg are investigating these movements.
