The role of elastase and proteinase inhibitors in polymorphonuclear leukocyte(PMN)-mediated injury to human umbilical cord venous endothelial cells (HUVEC) was investigated. Both purified human neutrophil elastase and PMN that were stimulated with serum-treated zymosan (STZ) induced detachment, but not lysis of HUVEC. PMN-, but not purified elastase-mediated detachment was enhanced by the presence of methionine, which indicates a role for reactive oxygen metabolites in PMN-mediated HUVEC detachment. Detachment of HUVEC could be inhibited by secretory leukocyte proteinase inhibitor or antileukoprotease (ALP), alpha 1-proteinase inhibitor (alpha 1-PI) and N-methoxy-succinyl-ala-ala-pro-val-chloromethyl ketone (CMK). At concentrations at which elastase-mediated detachment was maximally inhibited, ALP and CMK, but not alpha 1-PI, were also able to inhibit maximally PMN-mediated detachment. An explanation for this difference could be that the larger size of alpha 1-PI reduces the access of alpha 1-PI to the interface between the PMN and the HUVEC.
