Koblish H, Hansbury M, Bowman K, Yang G, Neilan C, Haley P, et al.
Mol Cancer Ther . 2010 Feb; 9(2):489-98. PMID: 20124451
Malignant tumors arise, in part, because the immune system does not adequately recognize and destroy them. Expression of indoleamine-2,3-dioxygenase (IDO; IDO1), a rate-limiting enzyme in the catabolism of tryptophan into...
