Question

Quizplus · Accepted Answer

Eosinophils have large granules that contain substances, such as major basic protein (MBP) and eosinophilic cationic protein (ECP), that specifically target large parasites. Macrophages do not have granules. Large granular lymphocytes (LGLs) and PMNs have granules, but those granule components are used for purposes other than killing large parasites. LGLs mainly kill virus-infected cells and tumor cells, and the granules in PMNs aid in killing small pathogens, such as bacteria, that are ingested by phagocytosis.
