Representative workflow contour plots and histograms from flow cytometry measurements of TLR2, TLR3, TLR7 and TLR9 expressions in NK cells. The blue gate in the FSC/SSC plot represents the PBMC population, and the red gate in the CD3-FITC/CD56-PerCP/Cy5 plot represents the CD56⁺ CD3⁻ NK cells. The red histogram represents background fluorescence from the fluorescence-minus-one (FMO) sample, and the black histogram represents the fluorescence from the TLR2-PE (a), TLR3-PE (b), TLR7-PE (c), and TLR9-PE (d) stainings
