Rho-kinase and myosin-II control phagocytic cup formation during CR3, but not FcgammaR, phagocytosis.
inhibition of the Rho --> ROK --> myosin-II pathway caused a decreased accumulation of Arp2/3 complex and F-actin around bound particles, which led to a reduction in CR-mediated phagocytic engulfment. FcgammaR-mediated phagocytosis, in contrast, was independent of Rho or ROK activity and was only dependent on myosin-II for particle internalization, not for actin cup formation. While myosins have been previously implicated in FcgammaR phagocytosis, to our knowledge, this is the first demonstration of a role for myosin-II in CR phagocytosis.
