Research Abstract

In this study, we established a cell line that constitutively expresses GFP-LC3, the molecular marker of autophagy, which can visualize the dynamics of autophagosome formation during influenza virus infection. We found that viral protein expression reduced in autophagy-deficient MEFs (MEFsAtg7-/-) which is relevant to the reduction in viral RNA synthesis including mRNA and genomic RNA. However, viral replication did not significantly affected by autophagy deficiency. Furthermore, viral entry into cell did not affected by autophagy deficiency, but Hsp 90 induction in response to viral infection and mTOR signalling were altered in MEFsAtg7-/-, suggesting that these autophagy-deficiency-induced host aberrant response might be responsive to the reduction of viral RNA synthesis.
