摘要：

The endothelial cell lining of blood vessels is now recognized as an active interface between blood and the underlying tissue. Modulation of cholesterol levels in several cell types has resulted in altered cell function. We have removed cholesterol from the endothelial cell membrane and have observed corresponding alterations in endothelial cell function. Following depletion of cholesterol from the endothelial cells, polymorphonuclear leukocyte adhesion to the cells was decreased. Angiotensin-converting enzyme activity of the endothelial cells was increased following removal of cholesterol from the endothelial cell membranes. The results of fluorescence polarization measurements suggest that these changes may be partially explained by altered membrane order. © 1991.
