IDO and IFN-γ gene expression.

<p>mRNA relative expression of IDO (A) and IFN-γ (B) in healthy controls (HC) and in multiple sclerosis patients with stable (SMS) or relapsing (AMS) disease. AMS patients were analyzed before (BT-AMS) or after the initiation of glucocorticoid treatment (DT-AMS). *p<0.05.</p

Kynurenine-to-Tryptophan ratio.

<p>Kyn/Trp in sera of multiple sclerosis patients with stable (SMS) or relapsing (AMS) disease and healthy controls (HC). AMS patients were analyzed before (BT-AMS) or after (DT-AMS) the initiation of glucocorticoid treatment. *p<0.05.</p
