(a) RAW64.7, P388D1, and J774 cells were subjected to cell surface staining or membrane-permeabilized staining with anti- mab. Gray histograms show staining with the secondary reagent alone. (b) CD11b + Ly6G - monocytes in the peripheral blood from WT, Tlr7 -/-, or Unc93b1 3d/3d (3d) mice were stained with anti- mab. Shaded histograms show staining with the secondary reagent alone.

Supplementary Figure. Anti- mab inhibits responses. BM-MCs (a), BM-cDCs (b), and BM-pDCs (c) were stimulated with the indicated TLR ligands. Anti- mab or IgG1 mab was administered in culture. TNFα and RANTES (a, b) or IL-6 and IL1 p4 (c) were measured by ELISA. The results are represented by the mean plus SD from triplicate wells. These data are representative of three independent experiments. Statistical analyses were calculated with Student s t-test (***: p<.5; ns: not significant).
