The identification and characterization of the various growth factors and cytokines have led to their use in treating a wide range of diseases like bone marrow failure, hematopoietic neoplasms, infectious diseases, and congenital and myeloproliferative disorders. Neutrophils are primarily responsible for maintaining normal host defenses against invading bacteria, cell debris, or foreign substances. Eosinophils increase in number during allergic reactions and parasitic infections. T lymphocytes are involved in cell-mediated immunity. Natural killer cells participate in innate or natural immunity, and their function is to destroy foreign cells. Granulocytes are phagocytic cells.
