CD8A and infection: The cytopathic effects of MVA-B infection (see Figure 2A and 2C) and the capacity of viable, mature and migrated MDDC to induce the proliferation of HIV-specific CD8+ T lymphocytes documented above suggest that these cells correspond to those MDDC that captured apoptotic MVA-infected MDDC and then cross-presented HIV antigens to HIV-specific CD8+ T cells.
