Changes in CD169 expression levels, CD8+ T lymphocyte count, and plasma viral loads during the rebound of CD8 T cells. Monocyte CD169 mean fluorescence intensities, plasma viral load, and CD8 counts are plotted together for each animal. CD8+ T lymphocyte count, but not plasma viral load, is temporally associated with CD169 expression on blood monocytes during the rebound of CD8 T cells.
