GSTM1 and Hyperglycemia: Then, 24 h after the stimulation with Hb-Hp1-1 complexes, suppression of IL-6 secretion was measured in both normo- and hyperglycemia, with the strongest suppression detected in NG after stimulation with 1 μg/mL Hb-Hp1-1 complexes (5.78 times, p-value < 0.001) and 3.9 times suppression after stimulation with 10 μg/mL Hb-Hp1-1 complexes (p-value < 0.01).
