Caveolin-1 and caveolae are critical for endothelial cell function and signal transduction, with important implications for the pathogenesis of atherosclerosis and vascular disease.
Caveolae are 50- to 100-nm cell-surface plasma membrane invaginations observed in terminally differentiated cells. They are particularly abundant in endothelial cells, where they are believed to play a major role in the regulation of endothelial vesicular trafficking and signal transduction. The use of caveolin-1-deficient mice has provided many new insights into the roles of caveolae and caveolin-1 in the regulation of endothelial cell function. These novel findings suggest an important role for caveolin-1 in the pathogenesis of cancer, atherosclerosis, and vascular disease.
