正常细胞应不合干扰素，就干扰素基因而言，在正常生理情况下，它是不表达的，须经诱导才能合成。但由于人处于环境中，可能接触各种各样诱导剂，干扰素在正常人体内的含量极微。据了解，病毒可诱导大量的干扰素，乙型肝炎、丙型肝炎是由病毒感染而引起的肝脏疾患，推论，病人 Normal cells should not interfere with interferon, the interferon gene, under normal physiological conditions, it is not expressed, to be induced to synthesis. However, since humans are exposed to the environment, they may be exposed to a variety of inducers, and the level of interferon in normal humans is minimal. It is understood that the virus can induce a large number of interferons, hepatitis B, hepatitis C is caused by the virus infection and liver disease, inference, the patient
