摘要:During lung infection with virus, airway-derived dendritic cells (DC) have been thought to be the dominant cell type involved in acquisition, transport, and direct antigen presentation for cytotoxic T lymphocyte priming. Contrary to this view, we have found that both an airway-derived CD8{alpha}-CD11b- DC subset and distinct CD8{alpha}+ lymph node resident DC can present class I-restricted antigens after lung infection with influenza virus or herpes simplex virus 1. Presentation by a nonairway-derived DC population argues that cytotoxic T lymphocyte priming may involve interplay between different DC subsets, not all of which originate within the site of infection.
