WebFeb 5, 2024 · Listeria monocytogenes hijacks host actin to promote its intracellular motility and intercellular spread. While L. monocytogenes virulence hinges on cell-to-cell spread, … WebMcGrath et al.[2] measured the velocity of Listeria cells overexpressing the ActA protein in a milieu of a frog egg extract supplemented with monomeric actin. In previous work [8], these authors found that motile Listeria cells displayed very little side-to-side movement, and moved forward in a series of 5 nm steps.
