"A virus can attach itself to a target cell by latching onto a molecule embedded in that cell's surface. In the case of adenovirus-associated virus, that viral-receptor molecule is already known. (The molecule obviously is there for some constructive purpose, which doesn't stop the invading virus from taking advantage of the mutual attraction.) Simply glomming on to the cell's surface isn't enough, though. To get to the all-important nucleus, where the genetic jewelry is ensconced, the virus has to penetrate the cell as well. Until now, the molecule on which adenovirus-associated virus hops a ride downtown was anybody's guess.
In the new study, Carette and his colleagues identified, in human cells, precisely that transport molecule. This discovery could lead to ways of raising or lowering the molecule's expression in different tissues so that therapeutic genes get delivered to their intended addresses, and nowhere else.
