12. A 38-year-old woman comes to the physician because of a 3-day history of an infected lesion on her right leg. Examination of the right lower limb shows an 8-cm lesion that is warm and fluctuant. A Gram's stain of an aspirate shows numerous neutrophils and gram- positive cocci in clusters. The tendency of activated neutrophils to migrate out of blood vessels into the extravascular areas is best explained by which of the following aspects of neutrophil activation? A) Enhanced activity of adhesion molecules B) Heightened phagocytic ability of neutrophils C) Increased release of platelet activating factor D) Increased synthesis of lysosomal enzymes E) Upregulated synthesis of Fc receptors
