Myeloperoxidase News and Research

RSS

Myeloperoxidase (MPO) is a peroxidase enzyme most abundantly present in neutrophil granulocytes (a subtype of white blood cells). It is a lysosomal protein stored in azurophilic granules of the neutrophil. MPO has a heme pigment, which causes its green color in secretions rich in neutrophils, such as pus and some forms of mucus.

Study reveals two enzymes help immune cells deploy pathogen-killing traps

A new study reveals that two enzymes help immune cells deploy pathogen-killing traps by unraveling and using the chromatin (DNA and its associated proteins) contained in the cells' nuclei to form defensive webs. The study appears online on October 25 in The Journal of Cell Biology.

Scientists show carbon nanotubes can be broken down by MPO

A team of Swedish and American scientists has shown for the first time that carbon nanotubes can be broken down by an enzyme - myeloperoxidase - found in white blood cells. Their discoveries are presented in Nature Nanotechnology and contradict what was previously believed, that carbon nanotubes are not broken down in the body or in nature.

Mortality in CAD patients: Key predictor identified

Coronary Artery Disease (CAD) hospitalizes more than 160,000 Canadians every year, and almost one quarter of those patients die from this common form of heart disease. But now a team of Vancouver-based researchers has identified a key predictor of mortality in CAD patients, which means that specialists can better determine how to treat and improve outcomes for patients with CAD.

New biomarkers in acute cardiac care

In conjunction with clinical assessment and the ECG, simple and rapid blood tests have become the standard for the detection of myocardial infarction. Starting in the year 2000, recommendations by the European Society of Cardiology and other major cardiology societies worldwide have begun to state uniformly that a rise in cardiac troponins - sensitive and specific markers for dying cells in the heart - is a prerequisite for the clinical diagnosis of myocardial infarction.
