In the lack of any one of the molecules, the researchers found that the vesicles merged completely with the membrane and disgorged almost all their cargo, which they had shown was an aberration in exocytosis, not the rule, as had been previously assumed. Together, the experiments demonstrate that cells employ some of the same molecules for importing and exporting cargo. ‘They use the same machinery for both,’ Jaiswal says. ‘This blurs the collection between endocytosis and exocytosis.
