  • Title: Axonal transport of protein in motor fibres of experimentally diabetic rats--fast anterograde transport.
    Author: Meiri KF, McLean WG.
    Journal: Brain Res; 1982 Apr 22; 238(1):77-88. PubMed ID: 6177381.
    Abstract:
    Fast axonal transport of radiolabelled proteins in motor fibres of rat sciatic nerves was studied after 14 days of streptozotocin-induced diabetes. The rate of fast transport as measured at two time intervals after application of [3H]leucine to the motor neurone cell bodies in the spinal cord was reduced by 21% in diabetic rats. There was no significant change in the time between injection of isotope and the start of fast transport. The amount of axonal transport of radiolabelled proteins as measured by accumulation of proteins proximal to a ligation on the sciatic nerve was also unchanged. The reduction in fast transport rate in the diabetic rats was eliminated by maintenance of normal blood glucose levels in twice daily insulin administration. The results are discussed with regard to the known effects of experimental diabetes on axonal transport in sensory fibres and to the role of fast axonal transport in peripheral neuropathies in general.
