Redefining Roles: A Paradigm Shift in Tryptophan–Kynurenine Metabolism for Innovative Clinical Applications

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(23), P. 12767 - 12767

The tryptophan-kynurenine (KYN) pathway has long been recognized for its essential role in generating metabolites that influence various physiological processes. Traditionally, these have categorized into distinct, often opposing groups, such as pro-oxidant versus antioxidant, excitotoxic/neurotoxic neuroprotective. This dichotomous framework shaped much of the research on conditions like neurodegenerative and neuropsychiatric disorders, well cancer, where metabolic imbalances are a key feature. effects significantly influenced by factors, including concentration particular cellular milieu which they generated. A molecule acts neuroprotective at low concentrations may exhibit neurotoxic elevated levels. oxidative equilibrium surrounding environment can alter function KYN from an antioxidant to pro-oxidant. narrative review offers comprehensive examination analysis contemporary understanding metabolites, emphasizing their multifaceted biological functions relevance numerous pathological underscores pressing necessity paradigm shift comprehension metabolism.
