On the right path: The mechanisms of endocytosis of cetuximab (C225) and its nanoconjugates have been elucidated in a pancreatic cancer cell line. By using gold nanoparticles as a scaffold, it is possible to switch the pathway for endocytosis from a Dyn-2-dependent caveolar mechanism to Cdc42-dependent pinocytosis/phagocytosis. Tailoring endocytotic mechanisms may enable specific intracellular pathways to be targeted.
