Title: ?d T Cells Provide Protective Function in Highly Pathogenic Avian H5N1 Influenza A Virus Infection
  • Document date: 2018_12_4

    Snippet: In summary, our study demonstrates for the first time that γδ T cells play an important role in the defense against HPAI H5N1 virus infection. γδ T cells could be directly activated by HPAI H5N1 viruses through natural trimers of HA proteins; this ability was dependent on sialic acid receptors on the surface of γδ T cells and on the HA glycosylation. Furthermore, HAinduced γδ T cell activation can be inhibited by CsA but not by wortmannin.....
    Document: In summary, our study demonstrates for the first time that γδ T cells play an important role in the defense against HPAI H5N1 virus infection. γδ T cells could be directly activated by HPAI H5N1 viruses through natural trimers of HA proteins; this ability was dependent on sialic acid receptors on the surface of γδ T cells and on the HA glycosylation. Furthermore, HAinduced γδ T cell activation can be inhibited by CsA but not by wortmannin or LY294002. Our results provide new insights about the immunoprotective role of γδ T cells in the defense against HPAI H5N1 virus infection and provide a novel strategy for controlling influenza virus infection in the future.
