[h=1]Immune Repertoire Diversity Correlated with Mortality in Avian Influenza A (H7N9) Virus Infected Patients.[/h] Hou D[SUP]1[/SUP], Ying T[SUP]2[/SUP], Wang L[SUP]2[/SUP], Chen C[SUP]1[/SUP], Lu S[SUP]3[/SUP], Wang Q[SUP]1[/SUP], Seeley E[SUP]4[/SUP], Xu J[SUP]3[/SUP], Xi X[SUP]3[/SUP], Li T[SUP]3[/SUP], Liu J[SUP]1[/SUP], Tang X[SUP]1[/SUP], Zhang Z[SUP]3[/SUP], Zhou J[SUP]1[/SUP], Bai C[SUP]1[/SUP], Wang C[SUP]5[/SUP], Byrne-Steele M[SUP]5[/SUP], Qu J[SUP]6[/SUP], Han J[SUP]5[/SUP], Song Y[SUP]1,[/SUP][SUP]3,[/SUP][SUP]7[/SUP].

[h=3]Abstract[/h] Specific changes in immune repertoires at genetic level responding to the lethal H7N9 virus are still poorly understood. We performed deep sequencing on the T and B cells from patients recently infected with H7N9 to explore the correlation between clinical outcomes and immune repertoire alterations. T and B cell repertoires display highly dynamic yet distinct clonotype alterations. During infection, T cell beta chain repertoire continues to contract while the diversity of immunoglobulin heavy chain repertoire recovers. Patient recovery is correlated to the diversity of T cell and B cell repertoires in different ways - higher B cell diversity and lower T cell diversity are found in survivors. The sequences clonally related to known antibodies with binding affinity to H7 hemagglutinin could be identified from survivors. These findings suggest that utilizing deep sequencing may improve prognostication during influenza infection and could help in development of antibody discovery methodologies for the treatment of virus infection.
