Sec-ure nanotubes with RalA and Exocyst

Long-range communication between animal cells can be accomplished through thin tunnelling nanotubes. The generation of these delicate structures involves dynamic remodelling of actin and the plasma membrane. Now, some of the proteins that help to build these intercellular conduits have been identified.
