To understand the … WebA method was established to measure tryptophan and kynurenine in serum simultaneously. Tryptophan is converted to kynurenine by the action of the enzyme indoleamine 2,3-dioxygenase induced by interferon-γ (IFN-γ). Since IFN-γ is a Th1-cell derived cytokine, an increased tryptophan degradation rate via the kynurenine pathway can be found when ...
