Host Species: human
Supplied as Each vial contains ~1.5 X 106 cells in 1 ml of 10% DMSO
Background
L-tryptophan (L-Trp) is an essential amino acid necessary for protein synthesis inmammalian cells and the L-Trp to kynurenine (Kyn) pathway is firmly established as a keyregulator of innate and adaptive immunity. Catabolism of L-Trp to Kyn maintains animmunosuppressive microenvironment by starving immune cells of L-Trp and releasingdegradation products of L-Trp that have immunosuppressive functions. Indoleamine 2,3-dioxygenases (IDO1 & IDO2), two of the rate limiting enzymes in this pathway, are upregulatedin many tumors, providing cancer cells with an avenue for immune evasion.

Monitor IDO1 pathway activity. Screen for activators or inhibitors of IDO1 in a cellular context
