Hypochlorous Acid 85-102 myeloperoxidase Homo sapiens 63-66 33539947-2 2021 In the presence of chloride ions and hydrogen peroxide (H2O2), MPO forms the oxidant hypochlorous acid (HOCl). Hypochlorous Acid 104-108 myeloperoxidase Homo sapiens 63-66 33539947-3 2021 Here we examined the short-term implications of HOCl produced by endothelial-transcytosed MPO for eNOS activity. Hypochlorous Acid 48-52 myeloperoxidase Homo sapiens 90-93 33539947-5 2021 Exposure of MPO-containing ECs to low micromolar concentrations of H2O2 yielded enhanced rates of H2O2 consumption that correlated with HOCl formation and increased eNOS enzyme activity. Hypochlorous Acid 136-140 myeloperoxidase Homo sapiens 12-15
