Macrophages cytokine milieu of culture supernatants treated with phenolic extracts obtained from WG HP and WB LP (0.5 mg mL⁻¹). Macrophages were cultured in a medium (control −), 100 ng mL⁻¹ LPS (control +) or 100 ng mL⁻¹ LPS + free (FP) and bound (BP) phenolic fractions, for 24 h. Data are the means ± standard deviation (n = 4). Different letters denote statistical dif-ferences among the experimental groups. Abbreviations: LPS: lipopolysaccharide from Esche-richia coli; WG HP: wheat grain high protein; WB LP: wheat bran low protein.
