In the type 1 diabetes group, the total AV+, tissue factor-expressing AV+/CD142+, neutrophil-derived AV+/CD15+ and AV+/CD45+/CD15+, and endothelial-derived AV+/CD309+ and CD309+/CD34+ cMVs were inversely correlated with HbA1c (r = ‐0.437, r = ‐0.515, r = ‐0.575, r = ‐0.529, r = ‐0.416, and r = ‐0.445, respectively; all p ≤ 0.01), however, only at inclusion. The gene discussed is CD34; the disease is type 1 diabetes mellitus.
