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.

New technology may provide solution to high risk of repeat heart attacks, say scientists

Up to 30 percent of heart attack patients suffer a new heart attack because cardiologists are unable to control inflammation inside heart arteries — the process that leads to clots rupturing and causing myocardial infarction or stroke.

Researchers uncover how typhoid pathogen manages to evade host's immune system

The life-threatening disease typhoid fever results from the ongoing battle between the bacterial pathogen Salmonella and the immune cells of the body. Prof. Dirk Bumann's research group at the Biozentrum of the University of Basel has now uncovered how the typhoid pathogen repeatedly manages to evade the host's immune system. Their findings are published in the scientific journal "Cell Host & Microbe".

Study shows high-fiber diet reduces risk of colon problems

Scientists have more reasons for you to eat fiber and not abuse antibiotics.

Immune system plays important role in heart's response to injury

The immune system plays an important role in the heart's response to injury. But until recently, confusing data made it difficult to distinguish the immune factors that encourage the heart to heal following a heart attack, for example, from those that lead to further damage.

UMMS researchers commissioned by Alpha-1 Project to develop PiZ antibody

Researchers at the University of Massachusetts Medical School (UMMS) have been commissioned by the Alpha-1 Project (TAP) to develop a PiZ antibody. The antibody will be used to track the presence of mutant alpha-1 PiZ protein in human blood serum, an essential tool in testing potential therapies for Alpha-1 Antitrypsin Deficiency (Alpha-1).

Scientists progress towards understanding how some bacterial cells escape being killed by antibiotics

Scientists have made an important advance in understanding how a subset of bacterial cells escape being killed by many antibiotics.

Research: SLPI protein produced by body in response to injury plays vital role in patients with ALF

Findings published in the American Association for the Study of Liver Diseases journal, Hepatology, indicate that infection, the commonest cause of mortality in patients with acute liver failure, may be decreased by inhibiting the activity of a protein found in saliva called SLPI.

Macrophages invade diabetic pancreatic tissue during early stages of type 2 diabetes

As people's waistlines increase, so does the incidence of type 2 diabetes. Now scientists have a better understanding of exactly what happens in the body that leads up to type 2 diabetes, and what likely causes some of the complications related to the disease. Specifically, scientists from Denmark have found that in mice, macrophages, a specific type of immune cell, invade the diabetic pancreatic tissue during the early stages of the disease.

THRIL could be novel biomarker for immune activation, potential target for inflammatory diseases

Sanford-Burnham Medical Research Institute scientists have discovered a new molecule that forms when certain white blood cells-macrophages-are stimulated in response to pathogens.

TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells

TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host's body.

UCLA researchers find no evidence of association between iron levels and atherosclerosis risk

A UCLA research team has found no evidence of an association between iron levels in the body and the risk of atherosclerosis, the hardening and narrowing of the arteries that leads to cardiovascular disease, the No. 1 killer in the U.S.

Experimental drug that targets macrophages decreases cancer's growth

An experimental drug that targets macrophages, a type of immune cells, in the microenvironment surrounding the lethal brain tumor glioblastoma multiforme decreased the cancer's growth and extended survival of laboratory mice with the cancer, scientists will report on Tuesday Dec. 17, at the American Society for Cell Biology annual meeting in New Orleans.

Cancer cells that fuse with macrophages play key role in the spread of cancer

Cancer cells that spontaneously fuse with macrophages, the immune system's healthy scavenger cells, play a key role in the metastasis, or spread of the cancer to other areas of the body, according to research to be presented Sunday, Dec. 15, at the American Society for Cell Biology annual meeting in New Orleans.

Airway alterations present even in young smokers without COPD

A study has found functional and inflammatory changes in the nasal and lower airways of young, healthy smokers in the absence of pulmonary function decline.

New mechanism explains why anti-tumor activity of specific immune suppressed during tumor growth

The Leuven-based VIB researchers have revealed a mechanism that explains why the anti-tumor activity of specific immune cells called macrophages is suppressed during tumor growth. They have also demonstrated that blocking the protein Nrp1 can restore this anti-tumor immune response.

Scientists use new method to map response of every salmonella gene to conditions in human body

Scientists have used a new method to map the response of every salmonella gene to conditions in the human body, providing new insight into how the bacteria triggers infection.

New finding links obesity and high-fat, high-sugar diets with changes in inflammatory status

Scientists have moved a step closer to an "obesity drug" that may block the effects of diets high in sugar and fats. In a new research report published in the December 2013 issue of The FASEB Journal, scientists show that there is an abnormal amount of an inflammatory protein called PAR2 in the abdominal fat tissue of overweight and obese humans and rats.

Researchers identify key immune cells that turn body's defenders against invading golden staph

When golden staph enters our skin it can identify the key immune cells and 'nuke' our body's immune response.

Researchers identify immune cell protein that sets off body's initial response against viral infection

A Massachusetts General Hospital-led research team has identified an immune cell protein that is critical to setting off the body's initial response against viral infection. The report that will be published in an upcoming issue of Nature Immunology and is receiving early online release describes finding that a protein called GEF-H1 is essential to the ability of macrophages - major contributors to the innate immune system - to respond to viral infections like influenza.
