Bottom Line: In patients with PAD, a significant decrease in mDCPs, pDCPs, and tDCPs was observed.We show for the first time that mDCPs, pDCPs, and tDCPs are significantly reduced in patients with PAD.Immunohistochemical analysis unraveled that the decrease in DCPs might be due to their recruitment into atherosclerotic plaques.

ABSTRACT
Peripheral artery disease (PAD) is a common manifestation of atherosclerosis. Inflammation is important for initiation and progression of the disease. Dendritic cells (DCs) as antigen-presenting cells play an important role in the immune system. Therefore, we hypothesize that, in patients with PAD, DCPs might be reduced in blood due to their recruitment into the vascular wall and induce a proinflammatory response. The numbers of myeloid DCPs, plasmacytoid DCPs, and total DCPs were analyzed by flow cytometry in blood of patients with PAD (n = 52) compared to controls (n = 60). Femoralis plaques (n = 12) of patients who underwent surgery were immunostained for CD209 and CD83 (mDCs) as well as CD304, CD123 (pDCs), and HLA-DR. In patients with PAD, a significant decrease in mDCPs, pDCPs, and tDCPs was observed. In immunostaining, markers indicative for mDCs (CD209: 16 versus 8 cells/0.1 mm(2), P = 0.02; CD83: 19 versus 5 cells/0.1 mm(2), P = 0.03) were significantly elevated in femoralis plaques compared to control vessels. We show for the first time that mDCPs, pDCPs, and tDCPs are significantly reduced in patients with PAD. Immunohistochemical analysis unraveled that the decrease in DCPs might be due to their recruitment into atherosclerotic plaques.

Follow-up frequency of circulating mDCPs, pDCPs, and tDCPs in patients with PAD compared with initial measurement. Absolute numbers of circulating mDCPs (a), pDCPs (b), and tDCPs (c) (cells/μL) are shown. The box plots indicate the median (line inside the box), 25th and 75th percentile (lower and upper boundary of the box), and 10th and 90th percentile (whiskers outside box).

Mentions: In the 8 patients who attended the follow-up measurement, DCPs were measured at least 4 weeks after initial DCP determination. For these 8 patients with follow-up measurements, we found comparable levels of relative and absolute numbers of mDCPs (0.16 versus 0.14 and 10.23 versus 9.10 cells/μL; P = n.s.), pDCPs (0.11 versus 0.07 and 8.96 versus 7.62 cells/μL; P = n.s.), and tDCPs (0.29 versus 0.25 and 21.33 versus 15.37 cells/μL; P = n.s.), compared to the 2nd measurement (Figure 3).
