Gene therapy or cell transplantation therapy has made great progress in recent years. We overview mediatophore as a potential medical usage for gene and transplantation therapies in the nervous system. The 16-kDa proteolipid mediatophore was shown to mediate the secretion of acetylcholine in a Ca 2+ -dependent manner. Mediatophore is known to be identical to the transmembrane c-subunit of the V0 sector of the vacuolar proton ATPase (ATP6V0C).Recent development of structural understandings reveals that ATP6V0C is not a simple pore-forming stalk enable to permeate transmitters.Therefore, it is time to review this topic revisited from the recent knowledge on ATPase.
