The main effector cells of this process are the [[neutrophils|neutrophils]] and [[Macrophages|macrophages]] which recognise the pathogens, or with the case of macrophages, cells that have undergone apoptosis too. Phagocytic cells target pathogens by using cell membrane receptors ("Pathogen Recognition Receptors") that recognise intrinsically foreign components of microorganisms (pathogen-associated molecular patterns; PAMPs); or those that have been opsonised with either [[Complement|complement component C3bi]] or [[Immunoglobulins|antibodies]]; or with the case of cells that have undergone apoptosis, externalised phosphatidylserine (a phospholipid in the cell membrane).
