Activated IFN-ɣ+ T cells, natural killer (NK) cells, tumor necrosis factor (TNF)-α+ monocytes, IL10+ and TNFα+ myeloid dendritic cells, and TNF-α+ plasmacytoid dendritic cells persisted at least until day 30 after infection (Figures 2, 3, 5, and 6). This evidence concerns the gene TNF and infection.
