Figure 2. LPS increased the ratio of KYN to TRP in the plasma independent of 1-MT.

Figure 2

CX3CR1−/− mice were implanted s.c. with either placebo or 1-MT filled pellets three days prior to i.p. injection of saline or LPS (0.5 mg/kg). Plasma was collected 72 h later and concentrations of (A) 1-MT, (B) KYN, and (C) TRP were determined. (D) The ratio of KYN to TRP in the plasma is shown. Means with different letters (a or b) are significantly different (p < 0.05) from each other.
