β-Defensin Strengthens Antimicrobial Peritoneal Mast Cell Response

Figure 3

Effect of BD-2 stimulation on TLR7 expression in PMCs. PMCs were incubated with medium alone (NS: nonstimulated cells) or BD-2 for 1 or 3 h at a final concentration of 1 μg/mL. Representative images showing TLR7 receptor cellular localization in permeabilized native, BD-2 stimulated for 1 h or BD-2 stimulated for 3 h PMCs analyzed by confocal microscopy. Single confocal sections (the midsection of cells) reveal the presence of receptors. Fluorescence intensity diagrams showing the distribution of fluorescence in cells were mounted.
