In order to fight pathogens, mast cells regulate inflammatory reactions of the immune system. Both mast cells and neutrophils are white blood cells and are critical for the body’s immune defense. A team of scientists around the immunologist Prof. Dr. Anne Dudeck and the bioengineer Jan Dudeck has discovered a crucial aspect of the communication between mast cells and neutrophils. These new findings may allow for developing innovative, targeted therapeutic strategies to dampen allergic responses and inflammatory reactions. The results have been published in the renowned journal Immunity.
