Similarly, the percentages of CD4+CD25+CD127-Treg cells (Figures 2B and 3B), CD8+CD25+CD127-Treg cells (Figures 2C and 3C), CD4+CD25+Foxp3+ cells (Figures 2D and 3D), CD4+CD25-Foxp3+ cells (Figures 2D and 3E), CD8+CD25+Foxp3+ cells (Figures 2E and 3F) and CD4+IL17+Th17 cells (Figures 2F and 3G) were also significantly higher in the UCC group and the CIN group compared with the control group (p < 0.05). Here, CD4 is linked to cervical squamous intraepithelial neoplasia.
