The liver stays in the center of drug metabolism that is regulated by xenobiotic receptors and endocrine factors during development, physiology and pathology. The intestine and liver are closely interacted and a role of intestine derived factors is emerging in critically regulating the endobiotic and xenobiotic metabolism in the liver. Novel medicine or technologies to treat human diseases will be developed inspired by these interactions. This symposium will bring the best knowledge, novel in vitro and in vivo technology, and application of intestine-liver crosstalk to audience with interest in novel drug development and pharmacology.
