Vesicles filled with neurotransmitters touch the cell membrane, thereby enabling their rapid-fire release, scientists report. They have succeeded in demonstrating that fusionable vesicles have a very special characteristic: they already have close contact with the cell membrane long before the actual fusion occurs. In addition, the research team also decoded the molecular machinery that facilitates the operation of this docking mechanism.
