Myeloperoxidase (MPO) is a peroxidase enzyme that in humans is encoded by the MPO gene on chromosome 17. [5] MPO is most abundantly expressed in neutrophils (a subtype of white blood cells ), and produces hypohalous acids to carry out their antimicrobial activity, including hypochlorous acid, the sodium salt of which is the chemical in bleach.
Myeloperoxidase deficiency is a disorder featuring lack in either the quantity or the function of myeloperoxidase–an iron-containing protein expressed primarily in neutrophil granules. [1] [2] [3] There are two types of myeloperoxidase deficiency: primary/inherited and secondary/acquired. [4]
This is the fusion of granules with the phagolysosome, releasing their contents, including myeloperoxidase. [10] As many microbicidal products are formed during respiratory burst, the importance of individual molecules in killing invading pathogens is not wholly understood.
An important diagnostic test is the presence of perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) with myeloperoxidase specificity [6] (a constituent of neutrophil granules) Depending on which organ is affected special tests can be performed, such as renal biopsy in patients with kidney failure or electromyography in patients with ...

New York’s new toll for drivers entering the center of Manhattan debuted Sunday, meaning many people will pay $9 to access the busiest part of the Big Apple during peak hours.
For instance, some people follow a schedule that includes 20-minute naps every four hours for a total of two hours of daily sleep. Others sleep for 90 minutes three times a day, for a total of ...
Animal heme-dependent peroxidases is a family of peroxidases.Peroxidases are found in bacteria, fungi, plants and animals. On the basis of sequence similarity, a number of animal heme peroxidases can be categorized as members of a superfamily: myeloperoxidase (MPO); eosinophil peroxidase (EPO); lactoperoxidase (LPO); thyroid peroxidase (TPO); prostaglandin H synthase (PGHS); and peroxidasin.
