When the structure of tunneling nanotubes (TNTs) challenges the very concept of cell

Cells communicate with one another much like humans do. This allows organs to work synchronously, which in turn enables them to perform a remarkable range of tasks. One such means of communication is via tunneling nanotubes (TNTs). In an article published in Nature Communications, researchers from the Institut Pasteur led by Chiara Zurzolo used advanced imaging techniques to study the structure of these nanotubes, and reports that the results challenge the very concept of a cell.
