MT-1 cells are treated with Kynurenine (10, 50 μM) for 48 h or 4 days , then subjected to analyze the level of cytosolic AHR and nuclear AHR by immunoblot. After 4-days treatment, Kynurenine (10, 50 μM) remarkably induces the expression of CYP1A1 and plus-strand genes in a dose-dependent manner. Both groups efficiently triggered the production of Tax protein, p19 and p24, although the accumulation of gp46 is no apparent.

L-Kynurenine (2 mg/mL; feeding water; from the 7th to 13th day of pregnancy). Kyn is used to treat infected IDO–/– pregnant mice. The adverse pregnancy outcomes of IDO –/– infected mice after treatment with exogenous Kyn are significantly improved. Mental status, uterus, developmental status of placentas and fetuses in the infected, IDO –/– infected and IDO –/– infected with Kyn treated groups.
