Partial Myeloperoxidase Deficiency
Acta Haematologica, 1982Neutrophil myeloperoxidase (MPO) activity was analyzed by a semi-quantitative cytochemical method in 268 subjects divided into several groups. 17 subjects with significantly reduced MPO activity were found: 11 of 23 in the preleukemia group, 2/14 AMLs, 1/20 myeloproliferative syndrome, 1/7 carcinoma with bone marrow metastases, 1/33 diabetes mellitus ...

Myeloperoxidase participates in innate immune defense mechanism through formation of microbicidal reactive oxidants and diffusible radical species. A unique activity is its ability to use chloride as a cosubstrate with hydrogen peroxide to generate chlorinating oxidants such as hypochlorous acid, a potent antimicrobial agent.

Human Immunology, 2012
In the current study, whether myeloperoxidase (MPO)-catalyzing reaction could influence the antigenicity of MPO was investigated. Hypochlorite acid, the main product of the catalytic reaction, could lower the binding between MPO-antineutrophil cytoplasmic antibodies (ANCA) and MPO when the available chlorine was higher than 0.031×10(-3) g/l.

Endothelium, Myeloperoxidase, Anti-Myeloperoxidase Interaction in Vasculitis
1993Antibodies to myeloperoxidase (MPO) are found in the sera of patients with microscopic polyarteritis and idiopathic crescentic glomerulonephritis. Their pathogenicity is unknown. Studies were carried out on the binding of MPO to cultured human umbilical vein endothelial cells and the recognition of endothelium-bound MPO by antibody to MPO.

[20] Human myeloperoxidase and hemi-myeloperoxidase
1986Publisher Summary This chapter describes human myeloperoxidase (MPO) and hemi-MPO. MPO is an enzyme found in the azurophilic granules of mammalian neutrophils and is also identified in human monocytes. Its function is to kill bacteria that have been phagocytosed by these cells.
