Annexin A2 Limits Neutrophil Transendothelial Migration by Organizing the Spatial Distribution of ICAM-1.

ICAM-1 is required for firm adhesion of leukocytes to the endothelium. However, how the spatial organization of endothelial ICAM-1 regulates leukocyte adhesion is not well understood. In this study, we identified the calcium-effector protein annexin A2 as a novel binding partner for ICAM-1.
