Anchored for action: a dual role for integrin β1 in mast cell perivascular positioning and vasoactivity to license leukocyte recruitment

Aaron Hoffmann, Sebastian Drube, Roland Immler, Konstantinos Katsoulis‐Dimitriou, Jan Dudeck, Kathleen Baumgart, Claudia Küchler, Tobias Franz, Stephan Fricke, Sascha Kahlfuß, Markus Sperandio, Anne Dudeck

This study shows that integrin β1 is essential for mast cell positioning around arterioles and their vasoactive function, which are critical for leukocyte recruitment during inflammation.
