Schematic illustration describing NLC–cell interactions and uptake mechanism. Briefly, NLC were transported into the cell via caveolin-mediated endocytosis. Membrane integrity and mitochondrial activity were not affected; there was no translocation of PS, cell morphology was comparable to the control, and cell–cell-contacts remained intact. Apoptosis was not induced, there was no increase in IL-8 release, but ROS production was increased.
