(F) DCs were infected with the unencapsulated pneumococcal strain T4R in the presence of 100 μM peptides, P2 or CP2 at MOI of 10 for 2 h. Immunofluorescence microscopy images show that in DCs treated with peptide P2 (but not the control peptide CP2), intracellular T4R (green) do not co-localize with MRC-1 (red), but with the autophagy protein LC3B (cyan). Images are representative of three independent experiments. Scale bars, 10 μm. In magnified images, scale bars, 5 μm. Arrows indicate regions of co-localization of intracellular T4R with MRC-1 and LC3B. (G) Quantification of percentage of intracellular S. pneumoniae (n=50) in infected DCs that co-localize with MRC-1 and LC3B. Data are mean±s.e.m from two independent experiments. **** denotes P <0.0001 by two-way ANOVA with Bonferroni post hoc test for multiple comparisons. n.s. denotes not significant. P values are shown in Appendix Table S4.
