Download scientific diagram | Function of dendritic cells in the immune response to viruses.Following the uptake of viral antigen, myeloid dendritic cells (mDCs) and plasmacytoid DCs (pDCs) migrate to lymphoid tissue to prime naive CD4+ T cells and CD8+ T cells. In addition, activated DCs produce a range of cytokines, such as interferon-α (IFNα), interleukin-12 (IL-12) and IL-15, which in turn activate natural killer (NK) cells and influence T cell survival and differentiation. Depending…
