Our results showed increased NF-κB translocation in vehicle-treated macrophages upon infection with F. nucleatum (Figures 5A, B) and P. gingivalis (Figures 5C, D) compared to Quercetin-treated cells indicating that Quercetin regulates oral bacteria-induced inflammatory cytokine response through its effect on NF-κB signaling pathway. Here, NFKB1 is linked to infection.
