Polyclonal Rabbit Purified E B IC FC
Indoleamine 2,3, dioxgenase is an ubiquitous mammalian enzyme that catalyzes the oxidative degradation of L-tryptophan to N-formylkynurenine. N-formylkynurenine is subsequently converted (via the kynurenine pathway) to a range of metabolites including xanthurenic acid and the neurotoxin quinolinic acid. IDO activity is induced in response to interferon gamma and requires heme as a cofactor. IDO activity in the mammalian eye results in the accumulation of xanthurenic acid in the lenses over time. The accumulation of xanthurenic acid in the lens leads to apoptosis like death in the epithelial cells of the lens and can be one of the leading causes of cataracts in the elderly. The accumulation of quinolinic acid and the corresponding depletion of tryptophan resulting from elevated IDO activity in the CNS of some AIDS patients is directly implicated in the development of AIDS-related dementia. Activation of IDO has also been linked to a range of other diseases, including polio, meningitis and sepsis.
