Fig. 2. In vivo kinetics of TCR activation during chronic infection.
P14-Nr4a1-GFP cells were adoptively transferred into mice 1 day prior high dose LCMV clone 13 infection. Animals were sacrificed at various time points. a Examples of flow cytometry plots showing expression of Nr4a1-GFP and PD-1 in P14 cells (gated on alive single CD8+ CD45.1+ cells) isolated from the spleen of naive or chronically infected mice at various days post infection (dpi). Kinetics of GFP frequency b and GFP median c of P14-Nr4a1 GFP+ cells. d Nr4a1-GFP expression in P14 cells isolated from different tissues 21 dpi compared to the signal observed in activated cells isolated from the spleen 1 dpi. Full circles b, c and bar plots d represent mean ± SD. Empty circles b, c show individual data points. One of two experiments is shown (n = 2 mice for 1 to 3 dpi and 3 mice for 7 to 28 dpi). Each dot represents an individual mouse. See also Supplementary Fig. 1. Source data are provided as a Source Data File.
