Fig. 5. CF macrophages have reduced TLR4 protein degradation and translocation to the lysosomal compartment.
(A) Representative western blot of TLR4 from WT and CF macrophages treated with protein synthesis inhibitor and challenged with LPS. (B) Mean ± SEM relative quantification normalized to beta-actin with time zero is set at 1 for 3 independent experiments. Statistical analysis was performed by two-sample t-tests; (C) IF for TLR4 (green), LAMP-1 (red) in WT (top) and CF (bottom) macrophages treated with LPS for 45 minutes; nuclei were stained with DAPI; (D) representative western blot (left) and relative quantification normalized to b-actin (right) for Rab7 in WT and CF macrophages untreated or challenged with LPS as indicated.
