| Outline of Final Research Achievements |
Puffer fish contains a powerful neurotoxin, tetrodotoxin (TTX) in liver, ovary, and skin. Puffer fish poisoning develops after the ingestion of these toxic tissues. Today, puffer fish poisoning occurs annually in Japan and many other countries and regions. This study examined the transport of TTX in human intestinal Caco-2 cell monolayers, and revealed that the transport of TTX across Caco-2 cell monolayers was achieved by transcellular transport pathway. Transport inhibition assay suggested that the transport of TTX was mediated by organic ion transporters. Identification of transporters that mediate intestinal absorption of TTX merit further research.
