Abstract

Mice were infected with lymphocytic choriomeningitis virus (LCMV) to determine if changes in CD1d expression occurred during an acute virus infection. It is interesting that a decrease in CD1d expression on splenic dendritic cells (DC) and macrophages (MΦ) was observed for at least 3 months post-LCMV infection, and vaccinia virus and vesicular stomatitis virus induced similar changes in CD1d upon infection with those viruses. The reduction of CD1d cell-surface expression on DC and MΦ was independent of interferon-γ and interleukin-12 expression but partially recovered in transporter associated with antigen processing-1-deficient mice, suggesting that CD8+ T cells may play a role. Thus, one consequence of the induction of a cellular immune response is a change in CD1d expression, which may constitute a key element in regulating antiviral immunity.
