However, our current understanding of NA antigenicity is incomplete. Here, we describe human monoclonal antibodies (mAbs) from a patient with a pandemic H1N1 virus infection in 2009. Two mAbs exhibited broad reactivity and inhibited NA enzyme activity of seasonal H1N1 viruses circulating before and after 2009, as well as viruses with avian or swine N1s. The mAbs provided robust protection from lethal challenge with human H1N1 and avian H5N1 viruses in mice, and both target an epitope on the lateral face of NA. In summary, we identified two broadly protective NA antibodies that share a novel epitope, inhibited NA activity, and provide protection against virus challenge in mice. Our work reaffirms that NA should be included as a target in future broadly protective or universal influenza virus vaccines. Human anti-N1 monoclonal antibodies elicited by pandemic H1N1 virus infection broadly inhibit HxN1 viruses in vitro and in vivo.,Hansen L, McMahon M, Turner HL, Zhu X, Turner JS, Ozorowski G, Stadlbauer D, Vahokoski J, Schmitz AJ, Rizk AA, Alsoussi WB, Strohmeier S, Yu W, Choreno-Parra JA, Jimenez-Alvarez L, Cruz-Lagunas A, Zuniga J, Mudd PA, Cox RJ, Wilson IA, Ward AB, Ellebedy AH, Krammer F Immunity. 2023 Aug 8;56(8):1927-1938.e8. doi: 10.1016/j.immuni.2023.07.004.
