Figure 4

Hypothalamus (A–C), pituitary gland (D–G) and head-kidney (H) relative expression of genes related to endocrine-immune processes of European seabass fed experimental diets (CTRL and TRP) during 15 days under stressful conditions or not (Ø), followed by a bacterial challenge. Hypothalamus: (A)—gr1, (B)—gr2 and (C)—il6. Pituitary gland: (D)—gr1, (E)—tph1α, (F)—htr2a, (G)—il1β. Head-kidney: (H)—gr1. Values are presented as means ± SD (n = 8). Multivariate ANOVA followed by Tukey post-hoc test (p ≤ 0.05). If the interaction was significant, Tukey post-hoc test was used to identify differences among treatments. Capital letters stand for significant differences between dietary treatments. Different low-case letters stand for statistically significant differences between sampling times. Different symbols denote significant differences between stress conditions.
