The nervous system is the internet of the human body and can in the same way transfer signals over long distances very quickly. Some of the most important elements in this signaling are the axons. They are projections of the nerve cells which send signals to other nerve cells or muscles. For instance, axons that jut out from nerve cells in the spinal cord can be over one meter long.

“We have found out, that the protein Rab2 has to be present and functioning properly in order for the   to send effective signals between the central  and the body. When we remove the protein in fruit flies we can see that the signal molecules are accumulate in the axons like in a traffic jam,” explains visiting researchers Viktor Karlovich Lund from the Department of Neuroscience.
