Loss of IBC BND cells in subjects with autoantibody-positive (AAb+) prediabetes and recent-onset type 1 diabetes (R/O T1D) and some FDRs. A: Diagram of the adsorbent used to identify and enrich for IBCs. B: Representative gating strategy from a healthy control subject (H/C) to identify anergic (BND) IBCs. Gates for IgM and IgD are drawn on the basis of T cells (CD19) and verified by using fluorescence minus one controls. C: BND cells (as a percentage of CD27 IBC-positive B cells) in peripheral blood of FDRs (n = 103); subjects with AAb+ prediabetes (n = 18), R/O T1D (n = 21), and long-standing type 1 diabetes (L/S T1D) (n = 21) and H/Cs (n = 49). D: BND cells (as percentage of CD27 IBC-positive B cells) in blood of FDRs of various age-groups (years). ***P < 0.001 by Student t test. ns, nonsignificant.
