Thymocytes from WT, itk-/-, sh2d1a-/-, and itk-/- sh2d1a-/- mice were stained with CD1d-tetramer and antibodies against CD4, CD8, TCRβ, HSA, Eomesodermin, and PLZF.
(A) Total thymic cellularity. Significant differences were seen between WT and itk-/- mice (p < 0.005), WT and sh2d1a-/- mice (p < 0.05), and WT and itk-/- sh2d1a-/- mice (p < 0.0005).
(B) Dot-plots show PLZF versus Eomes staining on CD4SP TCRβhigh HSAlow CD1d-tetramerneg thymocytes.
(C-D) Graphs show frequencies (C) and absolute numbers (D) of CD4 SP TCRβhigh HSAlow CD1d-tetramerneg cells expressing PLZF (left) or Eomes (right). n = 10-12 mice per group. Results are representative of four independent experiments. Statistical analysis was performed using a one-way ANOVA. ****p < 0.0001
