One study showed an enhancement of pro‐inflammatory monocyte and anti‐inflammatory T‐cell forces in BD patients,14 while another study reported that compared to healthy controls, BD patients presented an increased circulating proportion of monocytes (CD14+) and a lower proportion of T‐cell (CD3+) and cytotoxic T cells (CD3 + CD8+),15 which was consistent with our previous findings.16 This evidence concerns the gene CD8A and Behcet disease.
