WebAbstract Tumors can exploit the indoleamine 2,3-dioxygenase 1 (IDO1) pathway to create an immunosuppressive microenvironment. Activated IDO1 metabolizes tryptophan into immunosuppressive kynurenine, leading to suppressed effector T-cell (Teff) proliferation, allowing for tumor escape from host immune surveillance. IDO1 inhibition counteracts … WebJan 2, 2024 · Tryptophan 2,3-dioxygenase (TDO) is an enzyme that degrades tryptophan into kynurenine and thereby induces immunosuppression. Like indoleamine 2,3 …
WebIndoleamine 2,3-dioxygenase (IDO) 1 degrades tryptophan, causing immunosuppression. • IDO1 inhibitors attenuate tryptophan depletion and immunosuppression. • IDO expression levels vary between and within tumor types. • IDO biomarker-based patient stratification merits investigation.
