(A) Relative gene expression of TLR-4, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and interferon (IFN)-γ. (B) Cytokine expression of TNF-α, IL-1β, IL-6, and IFN-γ after the treatment of Aβ_1-42-stimulated primary human neutrophils with the PF from VOO (25 and 50 μg/mL) or hydroxytyrosol (HTyr, 41 μM) for 6 h. Values are means of the three independent experiments in triplicate, with their standard errors represented by vertical bars (** p < 0.01; *** p < 0.001 vs. Aβ_1-42-treated cells).
