SLOW AXONAL TRANSPORT OF LABELLED PROTEINS IN SENSORY FIBRES OF RABBIT VAGUS NERVE

Abstract Both rapid (415 mm/day) and slow (24 mm/day) rates of axonal transport of proteins were found in sensory fibres of rabbit vagus nerve after injection of [3H]leucine into the nodose ganglion in vivo. The slow phase of transport was dependent on contact between the cell bodies and the nerve trunk, and did not continue under in vivro conditions. The results suggest some difference between the mechanisms of fast and slow transport.
