31. Neutrophils are much more numerous than the longer-lived monocyte / macrophage phagocytes. 32. It is also expressed by monocytes and macrophages. 33. Additionally, 5-HT 2A mRNA expression has been observed in human monocytes . 34. Inhibition of CES1 by in particular organophosphates reduces tumor-killing activity by monocytes . 35. Macrophages, also known as monocytes , will phagocytize a wide range of molecules. 36. Macrophages come from monoblast progenitors that differentriate into promonocytes, which mature into monocytes . 37. Monocytes eventually enter the tissues and become macrophages.38. Fc receptors are also found on eosinophils, monocytes , macrophages and platelets in humans. 39. ADA2 is not ubiquitous but co-exists with ADA1 only in monocytes -macrophages. 40. Monocytes are also known as macrophages after they migrate from the bloodstream and enter tissue.
