2. Fig. 1
. The generation of 4 genotypes of DO10 lpr mice. Four genotypes of F2 mice bearing DO10 transgenic TCR (DO10 lpr mice; [1] H-2d/k, lpr/+, [2] H-2d/k, lpr/lpr, [3] H-2k/k, lpr/+, and [4] H-2k/k, lpr/lpr) were generated by crossing F1 mice (DO10 TCR transgenic mice × MRL-lpr/lpr mice) bearing DO10 transgenic TCR with MRL-lpr/lpr mice. DO10 lpr mice were analyzed for DO10 transgenic TCR expression, lpr genotype, Fas expression, and H-2 haplotype.

. The cell numbers of thymocytes and splenocytes in the 4 genotypes of DO10 lpr mice. The cell numbers of thymocytes and splenocytes from the 4 genotypes of DO10 lpr mice (8-10 weeks old) were counted. Data are means ± SEM for 14 mice in each group. Thymus: *P < .001, significantly different from the mean value of H-2d/k lpr/+ or H-2k/k lpr/+ mice. Spleen: *P < .05, significantly different from the mean value of H-2d/k lpr/+ mice.

4. Fig. 3
. Flow cytometry analysis (A ) and cell numbers (B ) of thymocyte subpopulations in the 4 genotypes of DO10 lpr mice. Thymocyte subpopulations in the 4 genotypes of DO10 lpr mice were analyzed by flow cytometry with anti–CD4-FITC and anti–CD8-PE mAb. Data are means ± SEM for 14 mice in each group. Double-positive (DP ) thymocytes: *P < .001, significantly different from the mean value of H-2d/k lpr/+ or H-2k/k lpr/+ mice. Double-negative (DN ) thymocytes: *P < .01 and **P < .001, significantly different from the mean value of H-2d/k lpr/+ and H-2k/k lpr/+ mice, respectively. CD4+ single-positive (SP ) thymocytes: *P < .05 and **P < .001, significantly different from the mean value of H-2d/k lpr/+ and H-2k/k lpr/+ mice, respectively; +P < .02, significantly different from the mean value of H-2d/k lpr/+ mice.

5. Fig. 4
. TCR expression on thymocyte subpopulations in the 4 genotypes of DO10 lpr mice. Thymocytes from the 4 genotypes of DO10 lpr mice were stained with biotinylated KJ1-26 (A ; DO10 transgenic TCR clonotype mAb) or biotinylated anti-TCR-αβ (B ), anti–CD4-FITC, anti–CD8-PE, and streptoavidin-Tricolor, and cells were analyzed by flow cytometry. This Figure represents 8 separate experiments. DN , Double-negative; DP , double-positive; SP , single-positive.

6. Fig. 5
. CD5 and CD69 expressions on CD4+CD8+ double-positive thymocytes in the 4 genotypes of DO10 lpr mice. Thymocytes from the 4 genotypes of DO10 lpr mice were stained with biotinylated anti-CD5 or biotin-ylated anti-CD69, anti–CD4-FITC, anti–CD8-PE, and streptoavidin-Tricolor; and cells were analyzed by flow cytometry. This figure represents 5 separate experiments. The mean fluorescence intensities of CD5 expression on double-positive thymocytes were 821, 513, 187, and 82 in the mice with H-2d/k lpr/+, H-2d/k lpr/lpr, H-2k/k lpr/+, and H-2k/k lpr/lpr, respectively. CD69high populations were 12.11%, 4.55%, 3.95%, and 2.48% of double-positive thymocytes in those mice, respectively.

8. Fig. 7
. DO10 transgenic TCR expression on CD4+ and CD8+ splenocytes in the 4 genotypes of DO10 lpr mice. Splenocytes from the 4 genotypes of DO10 lpr mice were stained with biotinylated KJ1-26, anti–CD4-FITC, anti–CD8-PE, and streptoavidin-Tricolor; and the cells were analyzed by flow cytometry to examine the expression levels of DO10 transgenic TCR on CD4+ and CD8+ splenocytes (A ). (B ). The cell numbers of KJ1-26–positive CD4+ and CD8+ splenocytes in the 4 genotypes of DO10 lpr mice. Data are means ± SEM for 8 mice in each group. *P < .05, significantly different from the mean value of H-2d/k lpr/+ mice.

. Proliferative responses of splenocytes to OVA in the 4 genotypes of DO10 lpr mice. Splenocytes (1 × 105) from the 4 genotypes of DO10 lpr mice were cultured without (open columns ) or with OVA (1 mmol/L; solid columns ) at 37°C for 72 hours in the absence (A ) or presence (B ) of 1 × 105 irradiated BALB/c (H-2d) splenocytes as antigen-presenting cells. Cells were pulsed with 3H-thymidine for the last 16 hours, harvested, and 3H incorporation was counted. This figure represents 3 separate experiments.
