Abstract：
:FcRIII (CD16) expression on neutrophils from 17 patients with chronic myeloid leukemia (CML) was studied by flow cytometry using monoclonal antibodies. A variable proportion of CD16-negative neutrophils were found both in CML patients in chronic phase (3 out of 8 patients) and in CML patients in hematological remission (3 out of 9 patients). Neutrophils with reduced FcRIII expression showed more defective chemiluminescence and phagocytosis than neutrophils with normal FcRIII expression. Circulating myeloid cells from three patients in chronic phase, showing a normal percentage of CD16-positive neutrophils, were isolated and fractionated by discontinuous Percoll gradients. This study showed that CD16 appears at the stage of metamyelocyte, that band cells and segmented neutrophils display an identical pattern of membrane FcRIII, and that the fluorescence intensity shown by metamyelocytes is different from that displayed by more mature cells. The association between low FcRIII expression and function abnormality could be suggestive of a defect in CML neutrophil maturation.
