...Trevor W. Stone The role of the amino acid tryptophan in the generation of 5-hydroxy-tryptamine (5-HT) has been expanded over the past 30 years with recognition that its oxidation by indoleamine-2,3-dioxygenase (IDO) results in the formation of kynurenine and metabolites which regulate neuronal...

...Amanda W.S. Yeung; Andrew C. Terentis; Nicholas J.C. King; Shane R. Thomas IDO1 (indoleamine 2,3-dioxygenase 1) is a member of a unique class of mammalian haem dioxygenases that catalyse the oxidative catabolism of the least-abundant essential amino acid, L -Trp ( L -tryptophan), along...

... the degradation of the essential aromatic amino acid tryptophan via the kynurenine pathway and could contribute to deficient immune responsiveness. Activated IDO is indicated by an increased kyn/trp (kynurenine/tryptophan) ratio. The aim of the present study was to investigate whether tryptophan degradation...

Rating of perceived exertion in the patients was higher at all time points measured, including at rest, relative to controls. Levels of free tryptophan (free Trp...

...V. Gentil; M. H. Lader; B. D. Kantamaneni; G. Curzon 1. Subcutaneous injection of adrenaline into normal male volunteer subjects caused large increases of plasma non-esterified fatty acids and free tryptophan, but plasma total tryptophan fell considerably. Therefore increases of the percentage...

... the groups was abolished. 4. Total plasma tryptophan concentrations were equal in the two groups. Free plasma tryptophan, however, was markedly reduced in the choreic group, and this appeared to be a result of a disturbed relationship between free tryptophan and NEFA concentrations. The abnormalities in free...
