Gangliosides, complex glycosphingolipids containing sialic acids, are synthesized in the lumen of the Golgi complex and appear unable to translocate from the lumenal toward the cytosolic surface of Golgi membrane to access the monomeric lipid transport. As a consequence, they can only leave the Golgi complex via the lumenal surface of transport vesicles. In this work, we analyzed the exocytic transport of the disialo ganglioside GD3 from trans-Golgi network (TGN) to plasma membrane in CHO-K1 cells, by immunodetection of endogenously synthesized GD3. We found that ganglioside GD3, unlike another luminal membrane-bounded lipid (glycosylphosphatidylinositol-anchored protein), trafficked from TGN to plasma membrane by a BFA-insensitive exocytic pathway. Moreover, dominant negative form of Rab11, which prevent exit of vesicular stomatitis virus glycoprotein (VSVG) from the Golgi complex, did not influence the capacity of GD3 to reach the cell surface. Our results strongly support the notion that most ganglioside GD3 traffics from TGN to plasma membrane by a non-conventional vesicular pathway where lateral membrane segregation of VSVG and GPI-anchored proteins from GD3 is required before exiting TGN.
