Knockdown of TLR4 inhibits LPS induced autophagy and bactericidal activity. After transiently transfected with negative control siRNA or TLR4 siRNA, the HMrSV5 cells were incubated with LPS (1.0 μg/ml) for 12 hours. (A) The panel shows representative images of western blots probed with antibodies against TLR4, Beclin-1, LC3-II and β-actin. (B) Densitometric analysis of the blots showing the ratios of TLR4 to β-actin in Figure 10A. (C) Densitometric anaysis of the blots showing the ratios of Beclin-1 and LC3-II to β-actin in Figure 10A. * and ** denote p < 0.05 and p < 0.01 respectively in Figure 10B and 10C (vs. control); # and ## denote p < 0.05 and p < 0.01 respectively in Figure 10B and 10C (vs. LPS). (D) Graph represents percentage of remaining E.coli at different time points in each group treated as described above. Data are mean values ± SD (n ≥3). * and ** denote p < 0.05 and p < 0.01 respectively (LPS vs. control); # and ## denote p < 0.05 and p < 0.01 respectively (LPS + TLR4 siRNA vs. LPS).
