immune system
• approximately 50% fewer mature CD8+ T cells in the thymus and spleen
• however, overall spleen and thymus cellularities are similar to controls
• splenocytes have impaired presentation of an OVA epitope that requires cleavage but not of an epitope that does not require cleavage
• presentation of multiple different types of antigens by dendritic cells in vitro is less able to support proliferation of T cells
• impaired presentation of lymphochoriomeningitis virus epitopes to T cells in vivo
• however, presentation of MHC class II epitopes (GP61 and NP309) is similar to controls
• level is about half that of controls
• levels are decreased on CD4+ and CD8+ T cells in the blood, spleen, lymph nodes and thymus, on lymph node B cells, on splenic macrophages, dendritic cells, and B220+ splenocytes

hematopoietic system
• approximately 50% fewer mature CD8+ T cells in the thymus and spleen
• however, overall spleen and thymus cellularities are similar to controls
