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.

IL-6 blocker use in severe COVID-19 increases risk of secondary infections

With many hundreds of thousands of deaths due to the current COVID-19 pandemic, there is a rush to find an effective vaccine or drug against the virus. A new study on the preprint server medRxiv* in May 2020 shows that the use of some biologically plausible drugs may be counterproductive, and care should be taken when trying out unproven therapies.

Researchers study the effects of hyperoxia on the lung development of germ-free newborn mice

Charitharth Vivek Lal, M.D., and University of Alabama at Birmingham colleagues have used a novel and first-of-its-kind newborn mouse model to study the effect of high oxygen concentrations, or hyperoxia, on lung development of newborn mice that are germ-free -- meaning no microbes colonizing their lungs.

Oral vaccination with cholera toxin helps counteract age-associated obesity

Here the research team tested a safe and well-established microbe-based immune adjuvant to restore immune homeostasis and counteract inflammation-associated obesity in animal models.

Association found between gene variant and lung disease in the form of systemic vasculitis

University of Tsukuba-led team reveals the association between a gene variant and a lung disease in the form of systemic vasculitis particularly prevalent in the Japanese, potentially providing a target for future therapies.

Single high-fat meal can set the stage for cardiovascular disease

A single high-fat milkshake, with a fat and calorie content similar to some enticing restaurant fare, can quickly transform our healthy red blood cells into small, spiky cells that wreak havoc inside our blood vessels and help set the perfect stage for cardiovascular disease, scientists report.

Artificial sweetener sucralose worsens gut inflammation in mice with Crohn's disease

In a study that has implications for humans with inflammatory diseases, researchers from Case Western Reserve University School of Medicine and colleagues have found that, given over a six-week period, the artificial sweetener sucralose, known by the brand name Splenda, worsens gut inflammation in mice with Crohn's-like disease, but had no substantive effect on those without the condition.

Biomarkers may help predict prognosis of gastric cancer patients with alcohol consumption habits

Alcohol consumption has been identified as a modifiable risk factor for cancers such as gastric cancer. A new report in the The American Journal of Pathology sheds light on how specific proteins interact with alcohol, and how that interplay impacts survival and response to platinum-based adjuvant chemotherapy in patients with gastric cancer who may or may not still be drinking.

Researchers evaluate use of regenerative human umbilical cord for in-utero spina bifida repair

In a study to be presented Saturday, Jan. 28, in the oral concurrent session at 8:45 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, researchers evaluated a possible regenerative patch by using human umbilical cord in two studies titled Cryopreserved Human Umbilical Cord (HUC) vs Acellular Dermal Matrix (ADM) for In-Utero Spina Bifida Repair and the study Conventional vs cryopreserved human umbilical cord (HUC) patch based on repair for in-utero spina bifida in a sheep model.

Consuming green tea with dietary iron may lessen health benefits of green tea

Green tea is touted for its many health benefits as a powerful antioxidant, but experiments in a laboratory mouse model of inflammatory bowel disease suggest that consuming green tea along with dietary iron may actually lessen green tea's benefits.

Statins benefit patients undergoing major lung resection, lower major complications

Statins have been shown to reduce complications from cardiovascular surgery. To determine whether statins might also help those undergoing major lung surgeries, a team at Memorial Sloan Kettering Cancer Center conducted a well-designed study that randomized patients to receive either a statin or placebo before and after surgery.

Study shows that plant-based vegan diet may lower heart disease risk in obese children

Obese children who begin a low-fat, plant-based vegan diet may lower their risk of heart disease through improvements in their weight, blood pressure, body mass index, cholesterol levels, insulin sensitivity, and high-sensitivity C-reactive, according to Cleveland Clinic research published online today by The Journal of Pediatrics.

Boston Heart Diagnostics announces commercial launch of FDA-cleared MPO test

Boston Heart Diagnostics Corporation, a pioneer in integrating next-generation diagnostics into personalized nutrition and lifestyle programs for patients with or at risk for heart disease, announced the commercial launch of an FDA-cleared MPO (myeloperoxidase) test, a key biomarker for inflammation. Studies show that MPO levels are useful predictors of near-term (one to six months) risk of heart attack or stroke.
