Biologists prove critical step in membrane fusion

o occur, to the point of sharing membranes," Wessel said. "So all that is needed is a puff of calcium from within the cell and fusion is complete. The process is quick because of hemifusion ?the vesicles are right there and ready to go."

Wong and Wessel said that their findings might help scientists find new ways to deliver drugs to cells. If membrane-bound drugs can be induced to hemifuse with target cells ?rather than fully fuse ?there is the potential to control the timing of drug delivery.
