Figure 1

Expression of CD4⁺CD25⁺CD127^−/low T cells (Tregs) in blood sample of pretreatment, posttreatment, and control groups (Pre-T: pretreatment, Post-T: posttreatment). (a) CD4⁺CD25⁺CD127^−/low lymphocytes shown by FACS. (b) CD4⁺ T cells percentage in peripheral blood lymphocytes. (c) CD4⁺CD25⁺CD127^−/low T cells percentage in CD4⁺ T cells (^∗𝑃<0.05, compared with Pre-T). (d) Comparison of peripheral blood Tregs in individual patients with thyroid papillary carcinoma before and after ¹³¹I radioablation.
