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.

Review of natural products with promising anti-SARS-CoV-2 potential

In a new study, researchers reviewed existing literature on naturally active products with therapeutic efficacy against SARS-CoV-2.

New radio-labeled molecule may allow a non-invasive approach to monitor inflammation in real time

Researchers at The University of Texas MD Anderson Cancer Center have developed a new radio-labeled molecule capable of selectively reacting with certain high-energy radicals that are characteristic of innate immune activity, which may allow a non-invasive approach to monitor inflammation in real time by positron emission tomography (PET) imaging.

Cardiovascular markers for predicting clinical outcomes in SARS-CoV-2 infection

In a recent study posted to the medRxiv* preprint server, an interdisciplinary team of researchers from Toronto, Canada, characterized the markers of endothelial function and developed micro ribonucleic acid (miRNA) expression atlas in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive and -negative patients admitted to the intensive care unit (ICU).

Hypercoagulability of the blood responsible for cardiac thrombosis in COVID-19 patients

Researchers examined autopsy tissue samples of hearts from patients who died early in the COVID-19 pandemic.

The antimicrobial properties of the lungfish cocoon

Researchers investigate if the immune system of lungfish plays a role in estivation.

Characterization of circulating neutrophils from hospitalized COVID-19 patients

A new preprint deals with the characterization of neutrophil phenotypes in an attempt to provide biomarkers that can predict severe disease in patients hospitalized with COVID-19.

Salivary markers of oxidative stress during severe COVID-19

An interesting study from researchers at the University of Sharjah, Sharjah, United Arab Emirates, presents evidence that an elevated level of expression of oxidant molecules may be correlated with severe infection and lung injury.

Pathogenic airway neutrophilia drives ARDS in Black patients with severe COVID-19 in case study

Researchers from the US used a systems immunology approach where they combined high-dimensional flow cytometry and multi-omics single-cell sequencing analyses of immune profiles taken from the airways and matching blood samples of Black/AA patients.

Researchers find natural metabolites help SARS-CoV-2 escape antibodies

An international team of scientists has identified a human molecule — biliverdin — as a potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) target. The binding of the heme metabolite to the N-terminal domain of SARS-CoV-2 is associated with the virus’s ability to dodge the immune system by suppressing antibody binding to the spike protein.

Circulating antiphospholipid antibodies drive endothelial cell activation in COVID-19

With the emergence of COVID-19 (coronavirus disease 2019), researchers have been closely investigating the complex interplay between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the human immune system, and COVID-19 disease severity.

DNase coated melanin-like nanospheres for sepsis treatment in severe COVID

As the treatment of severe COVID-19 is very difficult, the researchers from the Korea Research Institute of Biosciences and Biotechnology (KRIBB) suggested that DNase-1 can be utilized to dissolve the neutrophil extracellular traps (NETs), hence halting the further progression of COVID-19.

Common antioxidant enzyme catalase as COVID-19 treatment

A new paper by researchers from the USA and China and published on the preprint server bioRxiv in July 2020 discusses a new drug based on the catalase enzyme, which could play a vital part in reducing the inflammation associated with progressive and severe COVID-19 disease.
