RNA N6-methyladenosine methylation in influenza A virus infection

Influenza A virus (IAV) is a negative-sense single-stranded RNA virus that causes acute lung injury and acute respiratory distress syndrome, posing a serious threat to both animal and human health. N6-methyladenosine (m 6 A), a prevalent and abundant post-transcriptional methylation of RNA in eukaryotes, plays a crucial regulatory role in IAV infection by altering viral RNA and cellular transcripts to affect viral infection and the host immune response. This review focuses on the molecular mechanisms underlying m 6 A modification and its regulatory function in the context of IAV infection and the host immune response. This will provide a better understanding of virus–host interactions and offer insights into potential anti-IAV strategies.
