Fig. 4From: Kinetics of CD169, HLA-DR, and CD64 expression as predictive biomarkers of SARS-CoV2 outcomePeripheral blood white cell gating strategy (left panel). Monocytes, neutrophils, and lymphocytes are identified according to their CD64 expression and Side Scatter (SSC-A) features. The diagrams to the right show an example of very high monocyte CD169 upregulation in a patient with active COVID-19, mild neutrophil activation (CD64), and preserved monocyte HLA-DR expressionBack to article page
