IL7R and systemic lupus erythematosus: More specifically, pooling the data of four studies in which Tregs was identified as “CD25+CD127−” cells revealed a significant difference between SLE patients and controls [−1.093, (−2.002, −0.183), p = 0.018], but no significant difference was apparent when Tregs were defined as “CD25bright/highCD127low/−” cells [−12.392, (−37.922, 12.138), p = 0.341] or “CD25highCD127low/−FOXP3+” cells [−0.667, (−2.664, 1.331), p = 0.513] (Supplementary Figure 3 and Table 2).
