...Arthur M. Talman; Ryan Chong; Jonathan Chia; Tatyana Svitkina; Hervé Agaisse ABSTRACT Several bacterial pathogens hijack the actin assembly machinery and display intracellular motility in the cytosol of infected cells. At the cell cortex, intracellular motility leads to bacterial dissemination...

... in receptor trafficking that will impact on motility and invasion. Our results also highlight the importance of actin assembly pathways and NPFs in regulation of invasive migration through recycling of receptors, rather than (or in addition to) their possible role in actin-based protrusion.
