The results of the flow cytometric suggested that the surface antigens of CD8+ TRM cells including CD8, CD69, and CD103, had no significant difference among the three groups, while compared with the model group, the surface antigens of CD8 (p < 0.05), CD69 (p < 0.05), and CD103 (p < 0.05) in the APS group increased significantly (Figure 4). This evidence concerns the gene ITGAE and autoimmune polyendocrinopathy.
