FPR2 and Sepsis: Classical monocytes (FSC+SSC–CD45+CD66b–CD16loCD14hi) were isolated from peripheral blood using inertial microfluidics (Supplemental Figure 1 and Figure 3A), and surface expression of DRV1, ALX, and DRV2 receptors was determined for cells from healthy subjects (dark gray) and patients with sepsis (Figure 3B).
