This study focuses on the effect of interferon (IFN)-alpha on phagocytosis of FITC-labeled Escherichia coli by polymorphonuclear neutrophils (PMNs) in chronic myelogenous leukemia (CML). The phagocytic activity and capacity of PMNs from IFN-alpha treated patients (n = 17), untreated CML patients (n = 9) and from healthy donors (n = 20) were compared using flow cytometry. Both parameters of PMN phagocytosis were reduced in untreated CML and in IFN-alpha treated CML with Ph1 chromosome persistence but normal in IFN-alpha treated CML with Ph1 conversion. Thus, the phagocytic performance of PMNs in patients with chronic phase CML is significantly improved after successful treatment with IFN-alpha.
本研究聚焦于α干扰素(IFN)对慢性粒细胞白血病(CML)患者多形核中性粒细胞(PMN)吞噬异硫氰酸荧光素(FITC)标记的大肠杆菌的影响。使用流式细胞术比较了来自接受α干扰素治疗的患者(n = 17)、未治疗的CML患者(n = 9)以及健康供体(n = 20)的PMN的吞噬活性和能力。未治疗的CML患者以及伴有Ph1染色体持续存在的接受α干扰素治疗的CML患者的PMN吞噬作用的两个参数均降低,但伴有Ph1染色体转化的接受α干扰素治疗的CML患者的PMN吞噬作用的两个参数正常。因此,慢性期CML患者经α干扰素成功治疗后,PMN的吞噬性能显著改善。
