Characterizing T Cells in SCID Patients Presenting with Reactive or Residual T Lymphocytes

Figure 3

FOXP3 Treg cells in SCID patients. CD25 and FOXP3 expression levels in CD4⁺ T cells of pt1 (a), pt2 (b), pt3 (c), pt4 (d), pt5 (e), age-matched healthy control (f), and the mother of patient 1 (g) were detected using FACS analyses. Quadrants were set up based on staining with isotype control. Boxed numbers indicate the percentage of Treg cells within the CD4⁺ population.
