SNCA and neuroblastoma: This experiment evidenced that after the injection of α-synuclein into the wall of the small intestine, α-synuclein could arrive at the dorsal nucleus of the vagus nerve in the brainstem, a phenomenon which exhibited a time-dependence.[18] Moreover, live cell imaging in a differentiated neuroblastoma cell line demonstrated the coexistence of 2 axonal transmissions (rapid and slow) that were used in the transport of aggregated α-synuclein.
