Complement receptor 3 sends a signal to dampen the immune system

Researchers from The Children's Hospital of Philadelphia and The University of Pennsylvania reported that complement receptor 3 (CR3), a protein found on cell surfaces, inhibits dendritic cells, the sentinels of the immune system, from setting off an alarm signal that brings on a full immune response.
