Scientific Background :  IDO1 encodes indoleamine 2,3-dioxygenase (IDO) - a heme enzyme that catalyzes the first and rate-limiting step in tryptophan catabolism to N-formyl-kynurenine which acts on multiple tryptophan substrates including D-tryptophan, L-tryptophan, 5-hydroxy-tryptophan, tryptamine, and serotonin. IDO1 play a main role in a variety of pathophysiological processes such as antimicrobial and antitumor defense, neuropathology, immunoregulation, and antioxidant activity. IDO1 activity in tumor cells may act to impair antitumor responses (1). The efficacy of therapeutic vaccination of cancer patients might be improved by concomitant administration of an IDO inhibitor (2).
