D34A mutation does not influence the subcellular distribution of Unc93B1. (A and B) WT, D34A, or H412R Unc93B1-GFP was expressed in DCs from 3d mice. Their subcellular distribution was determined by confocal microscopy (left). Cells were also stained with a marker locating (A) ER or (B) lysosome (center). (right) Merged images. (C) WT Unc93B1-GFP (left) and D34A Unc93B1-cherry (center) were coexpressed in DCs from 3d mice. These cells were left unstimulated or stimulated with 5 µg/ml imiquimod, 1 µM CpG-B, or 1 µg/ml lipid A for 3 h, as indicated in the figure. Green and red images were merged (right). These experiments were repeated three times and the represented images are shown. Bars, 5 µm.
