Biochem/physiol Actions

TDO2 (tryptophan 2, 3-dioxygenase) is responsible for the cleavage of indole ring at the C2-C3 bond of L-tryptophan, thereby regulating tryptophan concentration. It is expressed in tumor cells and suppresses antitumor immune responses. During acute ethanol intake, TDO2 carries the kynurenine pathway via glucocorticoid-associated route. This can lead to the accumulation of neurotoxic metabolites along with the reduction of serotonin. The TDO2 gene is upregulated in brains of patients with Alzheimer′s disease and might be associated with making of neurofibrillary tangles and senile plaque. TDO2 is also responsible for antimicrobial and immunoregulatory activities.

In mammals, the regulation of local tryptophan concentrations by the IFN-gamma-i inducible enzyme IDO is a prominent antimicrobial and immunoregulatory effector mechanism. Here, we show for the first time that another tryptophan-degrading enzyme, the liver-specific tryptophan 2,3-dioxygenase (TDO), is also

Tryptophan 2,3-dioxygenase (TDO), one of the two key enzymes in the kynurenine pathway, catalyzes the indole ring cleavage at the C2-C3 bond of L-tryptophan. This is a rate-limiting step in the regulation of tryptophan concentration in vivo, and is thus

In response to acute ethanol consumption, tryptophan 2,3-dioxygenase (TDO) induces the kynurenine pathway (KP) through a glucocorticoid-mediated mechanism, which could lead to a dramatic accumulation of neurotoxic metabolites in association with serotonin depletion. As a result, interindividual variability in ethanol-induced

The endogenous ligand-activated aryl hydrocarbon receptor (AHR) plays an important role in numerous biologic processes. As the known number of AHR-mediated processes grows, so too does the importance of determining what endogenous AHR ligands are produced, how their production is
