TP13: Dynamics of anti-viral immunity against viral infection of the liver
Using sophisticated in vivo HBV infection models, we are able to trace adaptive immunity in real-time. With this, we have demonstrated that innate immunity stimulation is able to overcome dysfunctional CD8 T cells during chronic HBV infection and to restore anti-HBV immunity leading to clearance of the infection. Using single cell RNA sequencing, we identified a Tcf7+ progenitor cell population within the liver. Stimulation of these progenitor cells in a type I interferon dependent manner, leads to their proliferation and differentiation into effector cells eliminating HBV replicating hepatocytes. We now study in detail the intrahepatic localisation of those Tcf7+ progenitor cells and their functional properties.Brugger M, Laschinger M, Lampl S, Schneider A, Manske K, Esfandyari D, Huser N, Hartmann D, Steiger K, Engelhardt S, Wohlleber D, Knolle PA.
