| Research Abstract |
We here showed that type I and II IFN directly activated HSC and induced cell cycle entry and quiescence in HSC during virus infection. The IFN-mediated HSC activation was dependent on not only DC and NK cells, but also other IFN-producing cells. Moreover, IFN is important for inhibition of HSC mobilization and induction of HSC-autonomous immunity by IFN-induced proteins against intracellular virus.
