  • When physiological activity in goldfish visual system was abolished by repeated intraocular injection of tetrodotoxin (TTX), the fast axonal transport of radioactive amino acid-labeled protein in the optic axons was unaltered. However, the TTX treatment reduced the amount of [3H]glucosamine-labeled glycolipids that were axonally transported to the optic tectum, and may have decreased their rate of turnover in the tectum. A similar though smaller effect was observed for glucosamine-containing glycoproteins. These alterations in axonal transport may be the basis for at least some of the deleterious effects of TTX on axonal regeneration in this system.
