New influenza A Virus Entry Inhibitors Derived from the Viral Fusion Peptides.
Guangzhou, China. In Plos One, Dec 2014
By employing pseudovirus-based entry inhibition assays including H5N1 influenza A virus (IAV), and VSV-G, the mechanism study indicated that the antiviral activity may be associated with the interactions between the HA2 subunit and pFP, of which, the nascent pFP exerted a strong effect to interrupt the conformational changes of HA2, thereby blocking the entry of viruses into host cells.

In Bing Du Xue Bao, 2014
This review describes the research progress in conserved epitopes of influenza virus, the advances in the research and development of universal influenza vaccines based on the relatively conserved sequences of NP, M2e, HA2, and headless HA, the mechanisms of cross-protection, and the methods to improve cross-protection.
New vaccines against influenza virus.
Atlanta, United States. In Clin Exp Vaccine Res, 2014
The strategies of universal vaccines include the matrix 2 protein, the hemagglutinin HA2 stalk domain, and T cell-based multivalent antigens.
Atomic structure of the ectodomain from HIV-1 gp41.
Boston, United States. In Nature, 1997
These features, and the existence of a similar reversal of chain direction in the fusion pH-induced conformation of influenza virus HA2 and in the transmembrane subunit of Moloney murine leukaemia virus (Fig. 1a-d), suggest a common mechanism for initiating fusion.
