Mature dendritic cells (DC) are the most potent antigen-presenting
cells within the entire immune system. Interference with the function
of these cells therefore constitutes a very powerful mechanism for
viruses to escape immune responses. Several members of the
Herpesviridae family have provided examples of such escape strategies, including interference with antigen presentation and production of homologous cytokines. In this study we investigated the
infection of mature DC with herpes simplex virus type 1 (HSV-1) and the way in which infection alters the phenotype and function of
mature DC. Interestingly, the T-cell-stimulatory capacity of these DC
was strongly impaired. Furthermore, we demonstrated that HSV-1 leads to
the specific degradation of CD83, a cell surface molecule which is
specifically upregulated during DC maturation. These data indicate that
HSV-1 has developed yet another novel mechanism to escape immune responses.
