Domain 1 of the urokinase‐type plasminogen activator receptor is required for its morphologic and functional, β2 integrin–mediated connection with actin cytoskeleton in human microvascular endothelial cells: Failure of association in systemic sclerosis endothelial cells

Abstract

The reduced angiogenic properties of SSc MVECs can be explained by the effects of uPAR truncation and the subsequent loss of the beta2 integrin-mediated connection of uPAR with the actin cytoskeleton in these ECs.
