Differential regulation of ligand-induced TLR7/9 trafficking by Unc93B1 (A) WT Unc93B1-GFP and D34A Unc93B1-cherry were coexpressed in Ba/F3 cells, and live cells were imaged. The merged and differential interference contrast (DIC) images are shown. (B) Ba/F3 cells expressing cathepsin B+L and TLR9-GFP were further transfected with WT (left) or D34A (right) Unc93B1. These cells were left unstimulated (top) or stimulated with 100nM CpG-B for 60 min (bottom). Cells were stained with a lysosome marker. Green and red images were merged (left), or merged images were further imposed on DIC images (right). (C) TLR9-GFP in B was replaced with TLR7-GFP and 5 µg/ml imiquimod was used as the stimulant. These experiments were repeated four times and represented images are shown. Bars, 5 µm.
