Fig. 1. Actin rearrangements upon bacteria entry. HeLa cells were infected with FITC-coupled bacteria for the indicated times before fixation and actin labelling using Alexa546-coupled phalloidin. Notice that a bacterium is visible in each of the actin patches, which transiently appeared (5 minutes and 15 minutes, arrows). At later times, infection also induced a general actin remodelling (15 minutes and 45 minutes, asterisks).
