Template:PBB Indoleamine-pyrrole 2,3-dioxygenase (IDO or INDO EC 1.13.11.52) is an enzyme that in humans is encoded by the IDO1 gene.[1][2] This enzyme catalyzes the degradation of the essential amino acid L-tryptophan to N-formylkynurenine.[3]
Function
Indoleamine 2,3-dioxygenase is the first and rate-limiting enzyme of tryptophan catabolism through kynurenine pathway, thus causing depletion of tryptophan which can cause halted growth of microbes as well as T cells.
IDO is an immunomodulatory enzyme produced by some alternatively activated macrophages and other immunoregulatory cells (also used as an immune subversion strategy by many tumors). Interferon-gamma has an antiproliferative effect on many tumor cells and inhibits intracellular pathogens such as Toxoplasma and chlamydia, at least partly because of the induction of indoleamine 2,3-dioxygenase.
It has been shown that IDO permits tumor cells to escape the immune system by depletion of L-Trp in the microenvironment of cells. Indeed, wide range of human cancers such as prostatic, colorectal, pancreatic, cervical, gastric, ovarian, head, lung, etc. overexpress human IDO (hIDO).[4]
Inhibitors
Norharmane, via inhibition of indoleamine 2,3-dioxygenase exerts neuroprotective properties by suppressing kynurenine neurotoxic metabolites such as quinolinic acid, 3-hydroxy-kynurenine and nitric oxide synthase.[5] Rosmarinic acid inhibits the expression of indoleamine 2,3-dioxygenase via its cyclooxygenase-inhibiting properties.[6] COX-2 inhibitors down-regulate indoleamine 2,3-dioxygenase, leading to a reduction in kynurenine levels as well as reducing proinflammatory cytokine activity.[7] Alpha-Methyl-Tryptophan also inhibits indoleamine dioxygenase.[8]
