用新城鸡瘟病毒F株(NDV-F)体外诱导不同年龄的正常人外周血白细胞,使其产生α干扰素(α-IFN)。实验发现,≥60岁组白细胞产生α-IFN的能力低于<45岁组,初步推测老年人易发生肿瘤、病毒感染及免疫性疾病与其白细胞产生α-IFN能力低下有一定的关系。
Newcastle disease virus F strain (NDV-F) in vitro induction of normal human peripheral white blood cells of different ages to produce interferon (α-IFN). The experiment found that ≥ 60-year-old white blood cells to produce α-IFN less than 45-year-old group, initially speculated that the elderly prone to tumor, viral infection and immune diseases and their white blood cell production of α-IFN has a certain relationship.
