WebJun 14, 2024 · The kynurenine pathway is a major route for the catabolism of tryptophan and has an important role in the immune system. 17,21,32,44 The kynurenine pathway is initiated by cleavage of the indole ring, which is initiated by tryptophan 2,3-dioxygenase 2 (TDO-2), indoleamine 2,3-dioxygenase 1 (IDO-1), or IDO-2, which shares similarities with … WebThese species, which are largely herbivorous, however, dispose of Trp more rapidly and their TDO is activated by smaller doses of Trp than Trp-tolerant species. In general, sensitive species may possess a higher indoleamine 2,3-dioxygenase (IDO) activity which equips them to resist immune insults up to a point.
