Abstrakt: Tunneling nanotubes (TNTs) are open-ended, membrane-encased extensions that connect neighboring cells. They have diameters up to 1 μm but are able to expand to convey large cargos. Lengths vary depending on the distance of the cells but have been reported to be capable of extending beyond 300 μm. They have actin cytoskeletons that are essential for their formation, and may or may not have microtubule networks. It is thought that thin TNTs lack microtubules, while thicker TNTs have microtubular highways that use motor proteins to convey materials, including proteins, mitochondria, and nanoparticles between cells. Specifically, the presence of dynein and myosin support trafficking of cargo in both directions. The purpose of these connections is to enable cells to work as a unit or to extend cell life by diluting cytotoxic agents or acquiring biological material needed to survive.
