Did You Know That Cell Membranes Can Form Tunnels Between Cells?

💡 The Answer

• Called tunneling nanotubes (TNTs), these are thin membrane bridges connecting distant cells.
• TNTs allow direct transfer of molecules, organelles, and even pathogens between cells.
• They facilitate intercellular communication, especially in immune and cancer cells.
• TNTs are thought to play roles in the spread of signals and diseases like HIV.
