RAW264.7 macrophage cells were reverse transfected with either scrambled (Scr) or Rab1b siRNA. 48 h after transfection cells were infected with live or paraformaldehyde killed Y. pestis CO92 pCD1(-) pGEN-PEM7::DsRED (MOI 7.5). Cells were stained for LC3 and colocalization was determined by confocal microscopy. (A) Representative images showing bacterial colocalization with LC3 at 20 min post infection. The colocalization channel was defined using Imaris software. Asterisks denote bacteria not colocalized with LC3; arrowheads denote bacteria colocalized with LC3. Scale bar is 5μm. (B) Percent of YCVs that colocalized with LC3 at 20 min post-infection. (C) Percent of YCVs that colocalized with LC3 at 80 min post-infection. ns = not significant.
