Caveolae, which are a special type of lipid raft, are small (50-100 nm) invaginations of the plasma membrane in many vertebrate cell types, especially in endothelial cells and adipocytes.
For instance, Clathrin-coated Pit-mediated receptor internalization (caveolae pathway), at least in some cases, has been reported to traffic ADC to the cells.
The eNOS is located in the caveolae and T-tubes, whereas the nNOS is located in the sarcoplasmic reticulum.
Filipin (caveolae-mediated endocytosis inhibitor) was used to show that transferrin-PLGA NPs were endocytosed via caveolae pathway.
Caveolae Cholesterol Is Actively Consumed in Cholesterol Efflux from the Cells.
Caveolae are plasma membrane microdomains, composed by cholesterol, sphingolipids, and different coat proteins named caveolins, considered anchor points to molecules (in this context, insulin receptor and GLUT4), facilitating their interaction, in order to activate cell signaling and transport [91-93].
