J774A.1 murine macrophage cells were stimulated with LPS (10 µg mL⁻¹) and treated with [Nle¹, dLeu⁹, dLys¹⁰] at the concentration of 3 μM for 24 h. Thereafter, cell supernatants were assayed for IL-6 enzyme linked immunosorbent assay as pg mL⁻¹ and presented as means ± S.D. of three independent experiments. ^#### p ≤ 0.0001 vs. Ctrl group; ** p ≤ 0.01 vs. LPS group. Statistical analysis was performed by one-way ANOVA followed by Bonferroni’s for multiple comparisons.
