Mast cells (MC), well known for their effector functions in Th2 skewed allergic and also autoimmune inflammation, become increasingly acknowledged for their role in protection of health. It is now clear that they are also key modulators of immune responses at interface organs like skin or gut.

They also regulate harmful immune responses in trauma and help to successfully orchestrate pregnancy. (Source: Journal of Allergy and Clinical Immunology)
