  2. A Role for Taok2 in Listeria monocytogenes Vacuolar Escape

    • Wed, 03/16/2022 - 12:00
    • The Journal of Infectious Diseases
    • The bacterial pathogen Listeria monocytogenes invades host cells, ruptures the internalization vacuole, and reaches the cytosol for replication. A high-content small interfering RNA (siRNA) microscopy screen allowed us to identify epithelial cell factors involved in L. monocytogenes vacuolar rupture, including the serine/threonine kinase Taok2. Kinase activity inhibition using a specific drug validated a role for Taok2 in favoring L. monocytogenes cytoplasmic access.
