• Phagocytosis (cell eating) – occurs in specialized mammalian cells (so-called professional phagocytes, e.g., dendritic cells and macrophages) that engulf large and essential particles.
  • Viral entry by this pathway typically involves the formation of large extracellular projections, and the internalized virus is taken into a phagosome.
  • Actin and RhoA are typically necessary for this process.
