Table 4.

Changes of PD-L1 and PD-L2 expression on external blood mDC cells in two groups (x ± s).

Group	Cell	PD-L1	PD-L2
AF (n = 48)	mDCs	0.28 ± 0.10∗	1.32 ± 0.21
	CD4+	1.99 ± 0.28	1.25 ± 0.26
	CD8+	3.41 ± 0.87	0.95 ± 0.20
Control (n = 48)	mDCs	0.95 ± 0.31	1.40 ± 0.16
	CD4+	2.01 ± 0.39	1.30 ± 0.27
	CD8+	3.53 ± 1.08	1.02 ± 0.27

Note: Compared with the control group on mDC cells, ∗P < 0.05.
