The role of dendritic cell subsets in immunity to viruses

Abstract

Dendritic cells orchestrate the adaptive immune response. As well as presenting MHC-restricted antigen for T-cell activation, they provide all the co-receptor signals required for full T-cell priming. As a consequence, they play a central role in the immune response to infections caused by many pathogenic agents, including viruses. In recent times, it has become apparent that dendritic cells represent a particularly heterogeneous population with individual subsets playing specialized roles in response to infection.
