Macrophage News and Research

RSS

A macrophage is a type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.

Discovery could help enhance the effectiveness of immunotherapy against melanoma

Researchers at the University of Bern have discovered a mechanism in the body’s own immune system which is responsible for the maturation and activation of immune cells.

Ineffective immune responses may be responsible for COVID-19 mortality rates in men and the elderly

News-Medical speaks to Dr. Nicole Lieberman about her latest research that discovered delayed immune responses may affect COVID-19 mortality rates.

Animal data supports efficacy of baricitinib vs SARS-COV-2

The high burden of disease caused by the COVID-19 pandemic has led to much research on effective ways to mitigate the health, social, and economic impact of the spread of the infection. A recent study published on the preprint server bioRxiv* in September 2020 reports on the characteristics of the drug baricitinib when used as monotherapy to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

CNIC researchers uncover a mechanism explaining how macrophages regulate obesity

Macrophages are immune system cells. They are essential in the early response to infections, and they also have a key role in the proper functioning of our tissues and the regulation of obesity.

Researcher describes a new approach to study the process of wound healing

Our bodies frequently heal wounds, like a cut or a scrape, on their own. However patients with diabetes, vascular disease, and skin disorders, sometimes have difficulty healing.

Study identifies a cell-cleaning system that is key to keeping a healthy heart

Researchers of the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have discovered a cell-cleaning system that is key to keeping a healthy heart.

Smoke from wildfires may increase COVID-19 risk

The smoke the firefighters are breathing is heightening their risk of contracting the new coronavirus, with potentially life-threatening effects. Further, fighting the huge fires may make infection control measures such as hand washing and social distancing, challenging to perform.

India's whole-virion inactivated SARS-CoV-2 vaccine shows promise

Researchers in India have conducted a preclinical study demonstrating the safety and efficacy of a new candidate vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

New research reverses the understanding of kidney tumor growth

Newly published research has reversed our understanding of an aspect of kidney tumor growth. Researchers at Huntsman Cancer Institute at the University of Utah (U of U) discovered that two key proteins have opposite roles than what was previously believed.

New antitumor vaccines control melanoma growth in preclinical models

Combining their expertise in protein engineering and synthetic DNA technology, scientists at The Wistar Institute successfully delivered nanoparticle antitumor vaccines that stimulated robust CD8 T cell immunity and controlled melanoma growth in preclinical models.

DLnano-vaccines may be a promising strategy for cancer immunotherapy

Researchers designed DLnano-vaccines displaying 60 copies of protein parts derived from the melanoma-specific antigens Trp2 and Gp100 and tested these in mouse models of melanoma, observing prolonged survival that depended on CD8 T cell activation both in therapeutic and prophylactic settings.

Researchers identify proinflammatory lipids that precede onset of Type 1 diabetes in mouse model, children

Type 1 diabetes, or T1D, is an autoimmune disease in which the body's immune cells -; led by inflammatory macrophages -; attack and destroy the beta cells of the pancreas that produce insulin.

Sex-differential COVID-19 responses are mediated by kynurenic acid

Now, a new study by a research team from Yale University, USA, Edith Cowan University, Australia, and the University of Strathclyde, Scotland, and published on the preprint server medRxiv in September 2020 shows that kynurenic acid is the underlying factor which is responsible for these differences.

Allergic immune response against bacteria is not pathological but protective

Allergy is one of the most common diseases in Europe, it is estimated that more than 150 million Europeans suffer from recurring allergies and by 2025 this could have increased to half of the entire European population.

Study addresses the role of macrophage activation syndrome in COVID-19

Scientists review macrophage activation syndrome — a feature of the cytokine storm that kills patients with severe cases of COVID-19, as well as possible treatments.

8 Sep 2020

Seasonal influenza and COVID-19 risk

In a new study published on the preprint server medRxiv, researchers from Laval University and McGill University in Canada reviewed evidence from 18 relevant studies on a possible interaction between influenza vaccines on non-influenza respiratory disease (NIRD).

Scientists find new way to capture "live" images of immune cells inside the lungs

University of Calgary scientists have discovered how to capture "live" images of immune cells inside the lungs.

Obesity may cause irregular immune responses to COVID-19

Obesity may cause a hyperactive immune system response to COVID-19 infection that makes it difficult to fight off the virus, according to a new manuscript published in the Endocrine Society's journal, Endocrinology.

Study: BIRC2 overexpression could be a key marker for immunotherapy resistance

Johns Hopkins Medicine researchers have added to evidence that a gene responsible for turning off a cell's natural "suicide" signals may also be the culprit in making breast cancer and melanoma cells resistant to therapies that use the immune system to fight cancer.

SARS-CoV-2-RNA viremia is a robust marker of critical illness in COVID-19

A new study by a large team of Spanish researchers and published on the preprint server medRxiv* in August 2020 reports that the presence of viral RNA in the blood is a useful marker of impending acute disease and can help triage COVID-19 disease patients who will require hospital care.
