Abstract：
:The high-density lipoprotein (HDL) pathway in rat adrenocortical cells was studied at the electron microscopic level in vitro via colloidal gold labelling. Steroid hormone assays were performed to confirm that the cells remained intact, viable, responsive to ACTH under the applied conditions, and to reveal the steroidogenic effect of HDL. The gold-labelled HDL particles (HDL-Au) were observed on the surface of the parenchymal cells, often attached to the membranes of the microvilli, but rarely in coated pits and coated vesicles. HDL-Au was accumulated by non-coated vesicles, multivesicular bodies and lysosomes. The lysosomes were identified by means of a non-specific esterase reaction. It is concluded that HDL particles are internalized by both zona glomerulosa and zona fasciculata cells. HDL is required for the enhanced functional activity of these cells in long-term incubation, and the lysosomes are involved in the process.
