To determine whether the effects of endotoxin on cultured lung endothelium involve proteolytic mechanisms, we incubated bovine pulmonary arterial endothelial cells with endotoxin in medium 199 + 10% fetal bovine serum (FBS) in the presence and absence of several proteinase

Plasminogen plays an integral role in the inflammatory response, and this participation is likely to depend on its interaction with cell surfaces. It has previously been reported that isolation of human neutrophils from blood leads to a spontaneous increase in

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

Previously published work has indicated that polyunsaturated fatty acids (PUFA) may enhance neutrophil-mediated damage to host tissues. We have found that endothelial detachment was significantly increased by neutrophils pretreated with docosahexaenoic (22:6, n-3) and arachidonic (20:4, n-6) acids at 10-40
