CLEC4C and COVID-19: The median absolute numbers of DC subsets in healthy individuals were 6.226 cells/μL [3.85; 15.43] for CD1c+ cDC2s, 0.870 cells/μL [0.87; 1.78] for CD141+ cDC1s and 8.721 cells/μL [5.02; 18.21] for CD303+ pDCs (Figure 1, Panel B), while DC absolute counts in COVID-19 patients were 0.00 cells/μL [0.00; 0.58] for CD1c+ cDC2s, 0.00 cells/μL [0.00; 0.28] for CD141+ cDC1s and 2.01 cells/μL [0.91; 3.38] for CD303+ pDCs (Figure 1, Panel B).
