Phenotypic changes in neutrophil granulocytes after G-CSF administration in patients with acute lymphoblastic leukemia under chemotherapy.
Phenotypic changes in neutrophil granulocytes (NG) after G-CSF have been scarcely studied. Using flow cytometry, we analyzed the changes of CD11b, CD14, CD33, CD71, HLA-DR, CD10, CD16 and CD15 on NG after G-CSF treatment in 6 patients with ALL receiving intensification chemotherapy and in 10 control subjects. After G-CSF we found: expression of HLA-DR, a higher expression of CD11b, CD71 and CD14, a decrease in CD10 positivity, and fluoresence Intesity in CD15 and CD16. After administration of G-CSF, the NG of patients with ALL express an immature phenotype as well as markers of proliferation.
