Article Title: Enterohemorrhagic E. coli Requires N-WASP for Efficient Type III Translocation but Not for EspF U -Mediated Actin Pedestal Formation

doi: 10.1371/journal.ppat.1001056

Figure Lengend Snippet: ( A ) NW −/− fibroblast-like cells ectopically expressing GFP fusions to WASP/WAVE family members N-WASP, WAVE2, WASH, or WHAMM, or to WAFL, were infected with EPEC KC12/pEspF U , and examined after staining with DAPI to detect bacteria (blue) and Alexa568-phalloidin to visualize F-actin (red). ( B ) Genetic depletion of WAVE2 in N-WASP knockout cells does not affect pedestal formation. Extracts from NW −/− cells, WAVE2 −/− cells, or NW −/− cells harboring control vector or one expressing a WAVE2 siRNA, were resolved by SDS-PAGE and immunoblotted for WAVE2 or tubulin, as a loading control (Top panel). NW −/− /WAVE2 knockdown cells were infected with KC12/pEspF U , and examined after staining with DAPI to detect bacteria and Alexa568-phalloidin to visualize F-actin (Bottom panel).
