Abstract
We have previously shown that phosphatidylinositol-specific phospholipase C (PI-PLC) produced by Listeria monocytogenes activates a host protein kinase C (PKC) cascade which promotes escape of the bacterium from a macrophage-like cell phagosome. Here, we provide evidence linking bacterial PI-PLC and host PKC beta to phagosome permeabilization, which precedes escape.
