WebJul 1, 2024 · While modulatory effects of gut microbes on neurological phenotypes have been reported, the mechanisms remain largely unknown. Here, we demonstrate that indole, a tryptophan metabolite produced by tryptophanase-expressing gut microbes, elicits neurogenic effects in the adult mouse hippocampus. Websubstituted indole compounds4 based on the fact that IAA is known as a plant growth regulator. On the other hand, we conceived 1-hydroxyindole hypothesis5, which led us to an idea that the non-toxic metabolites of tryptophan, an essential amino acid in our body, should have the expected biological activity. the problem with dietary supplements
