Figure 1. Cell-free DNA and NETs are increased in the circulation of patients with primary antiphospholipid syndrome (APS).
A, Cell-free DNA was measured in the plasma of APS patients (n=26) or healthy controls. B, Circulating NETs were measured in the same plasma by MPO-DNA ELISA. C, Cell-free DNA was measured in sera of APS patients (n=52) or healthy controls. D, Correlation between cell-free DNA and circulating NETs (MPO-DNA complexes) in APS sera. *p<0.05 and **p<0.01. In addition to the individual data points, mean and standard deviation are also presented in panels A–C.
