On the cover: Location of the cross-reactive epitope 1G2 (red) on a pseudoatomic model of the mature duck Tembusu virus virion. The virions are depicted as 2.0-Å radius Cα atoms and are colored according to their E protein symmetry relationships (i.e., 2-fold [cyan], 3-fold [green], or 5-fold [yellow] symmetry). Chen, X., C. Li, W. Lin, T. Li, X. Li, X. Bai, S. Wulin, Q. Zhang, S. Li, M. Liu, J.-H. Liu, and Y. Zhang. 2020. A novel neutralizing antibody targeting a unique cross-reactive epitope on the hi loop of domain II of the envelope protein protects mice against duck Tembusu virus. J. Immunol. 204: 1836–1848.
