Entry of influenza A virus into host cells — recent progress and remaining challenges

Influenza A viruses (IAV) are a major burden for human health and thus the topic of intense research efforts. The entry IAV into host cells is particular interest as early infection steps ideal target intervention strategies. Here, we review recent key findings in field entry. Specifically, discuss identification novel receptors, emerging role viral neuraminidase entry, well progress from structural studies on hemagglutinin during fusion process matrix protein involved virus uncoating. We also highlight remaining gaps our understanding point out important questions ongoing
