Figure 2 Nature of de novo donor-specific HLA antibodies (dnDSA) in kidney transplant recipientsMost de novo DSA in kidney transplant recipients are HLA class II antigen-specific. Shown is the relationship between median fluorescence intensity (MFI) of de novo class I and class II IgG DSA and ability of C1q or C3d-binding capacity. For recipients with multiple dnDSAs, only the immunodominant dnDSAs defined by the highest IgG MFI are plotted. Some of the C3d+ DSA can be also positive for C1q, and vice versa.
