Figure 5Immunofluorescence microscopy and quantitative analysis for colocalization of M.tb with autophagosome marker LC3 in control siRNA -treated BMMs that were untreated or pre-treated for 5 hr with recombinant mouse IFN-γ and EVs from uninfected (EVs_Control) or M.tb-infected (EVs_M.tb) macrophages followed by a 24 hr infection with GFP-expressing M.tb. Mock, untreated. Quantitative data are the mean ± SD of three independent infections and all data shown are representative of at least three independent experiments. Scale bar, 5 μM. n.s., not significant; * p < 0.05 , ** p < 0.01 and *** p < 0.001 by two-tailed Student's t-test.Immunofluorescence microscopy and quantitative analysis for colocalization of M.tb with autophagosome marker LC3 (C and D) in RIG-I siRNA-treated BMMs. Quantitative data are the mean ± SD of three independent infections and all data shown are representative of at least three independent experiments. Scale bar, 5 μM. n.s., not significant; * p < 0.05 , ** p < 0.01 and *** p < 0.001 by two-tailed Student's t-test.(E and F) Immunofluorescence microscopy and quantitative analysis for colocalization of M.tb with markers LC3 in WT BMMs that were left untreated or pre-treated for 5 hr with recombinant mouse IFN-γ and EVs from uninfected (EVs_Control) or M.tb-infected (EVs_M.tb) macrophages, followed by a 24 hr infection with GFP-expressing M.tb.
