SELP and type 1 diabetes mellitus: Patients with T1DM had significantly higher percentages of platelet–monocyte (median (range): 34.50% (13.40–45.20%) vs. 23.50% (13.10–31.00%); Figure 2A) and platelet–granulocyte binding (median (range): 10.35% (5.70–31.30%) vs. 7.35% (2.60–25.20%); Figure 2B), as well as increased surface expression of P-selectin on platelets (median (range): 2.15% (1.00–4.30%) vs. 1.70% (1.10–3.30%); Figure 2C) compared with healthy subjects.
