By using modified vaccinia virus Ankara (MVA), the present study demonstrates that MVA-induced autophagy delivers cytosolic pathogen-derived components to the lysosomal compartment, which provides an opportunity for endogenous antigens to be presented on MHC II. Viral DNA replication or late gene products as well as the adaptor molecule MyD88 are necessary for triggering autophagy, indicating that recognition of MVA by PRRs like TLR7/8/9 may be a prerequisite for the induction of autophagy. These findings might be important for a targeted activation of CD4+ T cells using MVA-based vaccines.
