Gene expression in peripheral leukocytes of pre-weaned dairy calves after a 10-day oral supplementation of 5-hydroxytryptophan (5-HTP, 90 mg/d; n = 8), fluoxetine (FLX, 40 mg/d; n = 8) or control (CON; n = 8). Gene expression is reported as fold change (2−ΔΔCt) relative to CON saline-supplemented group. (A) Gene expression of immune surface markers and (B) cytokines after 10 days of 5-HTP oral supplementation. (C) Gene expression fold change of immune surface markers and (D) cytokines after 10 days of FLX oral supplementation. Black bars denote 5-HTP vs. CON gene expression fold change, and dotted bars denote FLX vs. CON gene expression fold change. The negative inverse of fold-change values <1 was calculated for visual representation of negative fold changes. (*) indicate significant differences (P ≤ 0.05) and (#) indicate tendencies (0.05 < P ≤ 0.10) between CON and FLX or CON and 5-HTP.
