Leukocyte trans-endothelial migration: JAMs add new pieces to the puzzle

Summary The molecular details of leukocyte transmigration through the endothelial barrier (also called diapedesis), which is the final step of leukocyte extravasation from the circulation to a given site of inflammation, are by far not well understood. The present review will focus on the different mechanisms potentially involved in leukocyte trans-endothelial migration. Both homophilic and heterophilic interactions between leukocyte and...
