干扰素具有抗病毒、抑制肿瘤生长和免疫调节作用等许多重要生物功能,所以,对其作用机制的研究一直受到广泛重视。其中,干扰素引起生物效应的一个重要途径是通过诱导一种特异的2′—5′寡聚腺苷酸合成酶,继而合成pppA2′p5′A2′p5′A(简称2′—5′P_3A_3)及其同 Interferon possesses many important biological functions such as anti-virus, inhibiting tumor growth and immunomodulatory effect. Therefore, the research on its mechanism of action has been paid more and more attention. Among them, an important way for interferon to cause biological effects is through the induction of a specific 2’-5 ’oligoadenylate synthase, followed by the synthesis of pppA2’p5’A2’p5’A (referred to as 2’-5’P_3A_3 ) And the same
