As shown in Figure 7A, the percentage of CCR7+ CD1c+ mDCs obviously increased and showed a significant increase at days 48 (12.74±3.56%, P = 0.021) and 62 (6.53±1.60%, P = 0.043) p.i, when compared with that during pre-infection (2.40±1.71%), while the percentage of CCR7+ CD1c+ mDCs was negatively correlated with that of CD1c+ mDCs in PBMCs (r = −0.375, P  = 0.017). Here, CCR7 is linked to infection.
