Figure Lengend Snippet: Figure 1. BTLA expression in the thymus and spleen is inversely related to CD5 expression. (a) Relative fluorescent intensities (RFIs) of BTLA (upper row) or CD5 (lower row) in CD4 SP T cells (left column) and CD8 SP T cells (right column) in the thymus and spleen (BTLA, n = 39; CD5, n = 24). To calculate the RFI of BTLA or CD5, mean fluorescence intensity (MFI) data were normalized to the average MFI of BTLA or CD5 of the thymic SP T cells in each individual experiment. (b) Representative histograms showing the proportion of BTLA+ CD4 SP T cells (upper row) in the thymus and spleen. Lower row shows the proportion of BTLA+ CD4 SP T cells (lower left) and BTLA+ CD8 SP T cells (lower right) in the thymus and spleen (n = 39). (c) Representative flow cytometry dot plot (left) and histogram (right) of the indicated markers in splenic TCRβ+ cells from 7 to 10 week old B6.Rag2pGFP mice. (d) RFIs of BTLA (top panels) and CD5 (lower panels) on mature (GFP−) or newly generated (GFP+) SP T cells in the spleen (n = 11). Data are normalized to the average BTLA MFI or CD5 MFI of the GFP negative splenic SP T cells in each individual experiment. (e) CD5 expression on CD4 SP T cells and CD8 SP T cells from thymus (left) or spleen (right) and their corresponding representative histograms (lower rows) from WT (n = 24; B6.Foxp3GFP and B6.Nur77GFP), Btla−/− (n = 22; B6.Foxp3GFP Btla−/− and B6.Nur77GFP Btla−/−) and Pdcd1−/− (n = 6; B6.Foxp3EGFP Pdcd1−/−) mice. (f) Nur77-GFP expression. Dots indicate individual mice from six to nine independent experiments (a,b,e) or two independent experiments (c,d,f). *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.

Figure Lengend Snippet: Figure 5. Loss of BTLA early in T cell ontogeny generates autoimmune disease. (a) We adoptively transferred 20 × 106 FLC pooled from 8 to 10 embryonic day 14–16 B6Cre/ERT2+/− (WT) or B6Cre/ERT2+/− Btlafl/fl (fl/fl) foetuses to 7 week old Rag–/– mice on day 0 (n = 3 recipients per group), followed by tamoxifen injection on days 0, 1, 3, 5 and 6. Recipient mice were monitored for signs of disease for eight weeks post-FLC transfer. (b) MFI of CD5 in CD4 T cells (top) and CD8 T cells (bottom) with respective representative histograms of peripheral T cells in the recipients of FLC from B6Cre/ERT2+/− and B6Cre/ERT2+/− Btlafl/fl at eight weeks post-tamoxifen. Dots indicate data from individual mice; **p < 0.01. (c) Left panel: disease incidence in recipients of B6Cre/ERT2+/− (blue line) B6Cre/ERT2+/− Btlafl/fl (black dashed line) FLC. Survival curves were significantly different, p = 0.02. The grey rectangle indicates the range, in days, at which the first T cells were detected in the peripheral blood after FLC transfer. Right panel: weight changes in recipients of B6Cre/ERT2+/− Btlafl/fl FLC or B6Cre/ERT2+/− FLC. The red box on the X-axes indicates the tamoxifen treatment period. The presence (filled) or absence (empty) of disease signs is depicted on the far-right panel. (d) Flow cytometry gating (top). A representative histogram of BTLA expression in the T and B cells populating the periphery of B6Cre/ERT2+/− Btlafl/fl FLC recipient mice (middle) or B6Cre/ERT2+/− Btlafl/fl FLC recipient mice (bottom) at four weeks post-FLC transfer is shown.
