绪言已证明病毒感染诱导的杀伤 T 细胞对病毒感染细胞有特异的杀伤作用,抗病毒的中和抗体也很早就进行过反复的研究。另一方面,宿主抗病毒的防御机理中,有巨噬细胞和干扰索等对病毒感染不具有特异性的细胞或体液因子参与,但因其多数是无明显抗原刺激和诱导而产生的非特异反应,所以也称“自然抵抗力”。 Introduction It has been demonstrated that virus-infected killer T cells have a specific killer effect on virus-infected cells. Antiviral neutralizing antibodies have also been studied repeatedly. On the other hand, host defense mechanisms of antivirus include macrophages and interference cells such as cytokines or humoral factors that are not specific to virus infection, but most of them are nonspecific due to obvious antigen stimulation and induction Reaction, it is also called “natural resistance”.
