11. Leukapheresis, typically for granulocytes , is a rarely performed blood donation process. 12. Eosinophils are terminally differentiated granulocytes found in most mammals. 13. They are derived from monocytes, which are leukocytes, but not granulocytes . 14. The granulocyte macrophage colony-stimulating factor receptor is a IL-5. 15. A granulocyte differentiates into a distinct cell type by a process called granulopoiesis. 16. Granulocytes selectively kill the promastigotes by oxidative mechanism, while amastigotes are resistant.17. The bacteria normally infects and grows inside human immune system white cells called granulocytes . 18. Neutropenia indicates a deficiency of neutrophils ( the most common granulocyte cell ) only. 19. These underdeveloped promyelocytes, if fully matured, would have been the missing granulocytes . 20. The ? subunit contains a binding site for granulocyte macrophage colony-stimulating factor.
