Induction of autophagy has been shown to be beneficial for the replication of poliovirus, a phenomenon that might also apply for other picornaviruses. We demonstrate that de novo synthesis of human rhinovirus type 2 (HRV2), an HRV of the minor receptor group, is unaffected by tamoxifen, rapamycin, and 3-methyladenine (3-MA), drugs either stimulating (tamoxifen and rapamycin) or inhibiting (3-MA) autophagic processes. Furthermore, LC3-positive vesicles (i.e., autophagosomes) are not induced upon infection. Therefore, multiplication of this particular picornavirus is not dependent on autophagy.
自噬的诱导已被证明对脊髓灰质炎病毒的复制有益,这一现象可能也适用于其他小核糖核酸病毒。我们证明,2型人鼻病毒(HRV2,小受体组的一种HRV)的从头合成不受他莫昔芬、雷帕霉素和3-甲基腺嘌呤(3-MA)的影响,这些药物要么刺激(他莫昔芬和雷帕霉素)要么抑制(3-MA)自噬过程。此外,感染后不会诱导产生LC3阳性囊泡(即自噬体)。因此,这种特定小核糖核酸病毒的增殖不依赖于自噬。
