Background
L-tryptophan (L-Trp) is an essential amino acid necessary for protein synthesis in mammalian cells.The L-Trp to kynurenine (Kyn) pathway is firmly established as a key regulator of innate and adaptive immunity. Catabolism of L-Trp to Kyn maintains an immunosuppressive microenvironment by starving immune cells of L-Trp. Additionally, the released degradation products of L-Trp have immunosuppressive functions. Indoleamine 2,3-dioxygenases (IDO1 & IDO2), two of the rate limiting enzymes in this pathway, are upregulated in many tumorsand provide cancer cells with an avenue for immune evasion.
Application
Monitor IDO2 pathway activity. Screen for activators or inhibitors of IDO2 in a cellular context.
