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