Increased CD4⁺CD8⁺ Double-Positive T Cell in Patients with Primary Sjögren’s Syndrome Correlated with Disease Activity

Figure 1

The frequency of peripheral DPT cells was increased in patients with pSS. (a) CD3⁺ cells were gated, and representative data of DPT were shown for healthy controls (upper panel) and pSS patients (lower panel). (b) Summary data of the frequency of peripheral DPT cells were shown for healthy controls in comparison with pSS patients. (c) Summary data for frequency of peripheral DPT cells were shown for patients receiving or not receiving immunosuppressive treatment before admission. Each dot represents one individual donor. The Mann-Whitney test was used for comparison between the two groups. The error bars represent the median with interquartile range.
