Figures & data
Figure 1 Models showing endocytic pathways revealed by positively (A) and negatively (B) charged nanogold. (A) Positively charged nanogold seems to be internalised in the organelle rich zone both by clathrin-dependent (purple vesicles) and -independent endocytosis (green vesicles). In the first case endocytic vesicle are recycled to exocytosis through the Golgi apparatus (blue arrows), in the other case vesicles are transported to the TGN and then directed to the degradative pathway (black arrows). After 2 hours incubation gold particles are seen also within smooth ER between SVs in the clear zone. (B) Internalization of negatively charged nanogold is internalised in the clear zone. A clathrin-dependent internalisation seems to be responsible for the endocytic pathway leading to vacuoles (purple vesicles, black arrows). It is not know at the moment if internalisation of vesicles cycling in the tip region (orange vesicles) requires the formation of the clathrin coat.
