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.

INT-777 shows promise against metabolic syndrome

Heart disease is a major cause of death in industrialised countries, and is strongly associated with obesity and diabetes. Many scientists believe that what links these conditions is a chronic, low-grade inflammation.

Study reveals mechanism of action of laquinimod in patients with RRMS

Laquinimod is an orally available synthetic compound that has been successfully evaluated in phase II/III clinical studies for the treatment of relapsing-remitting multiple sclerosis (RRMS).

Titanium particles from artificial joints may play a direct role in painful inflammation

Many people with painful, creaky knees and hips find relief after replacing their bad joints with new artificial joints made from titanium. But some of these people develop painful inflammation that can lead to bone destruction and loosening of the new joint. A new study led by researchers at the University of Medicine and Dentistry of New Jersey and published by the Journal of Immunology suggests that tiny titanium particles that flake away from the artificial joints through normal wear and tear may play a direct role in that inflammation.

Inovio announces results from SynCon avian influenza vaccine Phase I study

Inovio Pharmaceuticals, Inc., which is advancing synthetic vaccines to fight cancers and infectious diseases, announced today that a single intradermal (ID) electroporation boost of its SynCon avian influenza vaccine generated HAI titers against six different, unmatched strains of H5N1 - a distinct new clinical achievement on the global research community's path to develop universal influenza vaccines.

Researchers identify hepcidin hormone as potential target for atherosclerosis

Researchers at Emory University School of Medicine have identified hepcidin, a hormone that regulates iron levels in the body, as a potential target for treating atherosclerosis.

Severity of smoke-inhalation injury may play a role in overall pulmonary inflammatory response

A study of burn patients has found that those who suffered the most severe smoke inhalation also had more inflammation and spent more time on ventilators and in intensive care.

Leading alcohol researchers to discuss latest genetic findings at Loyola meeting

Leading alcohol researchers from the United States and Canada will discuss their latest findings at an all-day meeting Nov. 18 at Loyola University Chicago Stritch School of Medicine.

Mtb produces specific protein that allows it to defuse and bypass body's security system

Tuberculosis, which kills over 2 million people each year, is caused primarily by infectious bacteria known as Mycobacterium tuberculosis - or Mtb. Mtb targets human immune cells as part of its strategy to avoid detection, effectively neutralizing the body's immune response.

Classical DCs associated with protection against atherosclerosis

Atherosclerosis, commonly referred to as "hardening of the arteries," is a major risk factor for heart attack and stroke. The cause of atherosclerosis is not well understood but, for some time, chronic inflammatory immune responses have been implicated in driving disease pathology. Now, a new study, published online on November 10th by Cell Press from the journal Immunity, identifies a type of immune cell that is not associated with promoting disease, but with protection against atherosclerosis.

New studies could fundamentally change medical treatment of liver cancer

Scientists at the Helmholtz Zentrum München have played a major role in two studies that could fundamentally change the medical treatment of liver cancer. Doctors are now able to determine the degree of aggressiveness of the tumour in the early stages and can thus devise an individualised treatment plan.

New data from Novartis' ACZ885 Phase III study on SJIA

Novartis announced today new pivotal Phase III data showing 45% of children with active systemic juvenile idiopathic arthritis (SJIA) were able to substantially reduce their use of oral corticosteroids (often described as steroids) within 28 weeks of commencing treatment with ACZ885.

Scientists identify key mechanism of tumor metastasis

Scientists at Dalhousie University in Nova Scotia have identified a key mechanism of metastasis that could lead to blocking tumor growth if their findings are confirmed.

Scientists discover Leishmania parasite with juggling chromosomes

Scientists found a deadly parasite with some of its chromosomes in duplicate, others in triplicate, while still others are present four or even five times. Moreover, the copy number varies between individuals. Such a bizarre occurrence has never before been found in nature, in any organism. As a rule, chromosomes should come in couples. The scientists, from the Institute of Tropical Medicine (ITG) and the Wellcome Trust Sanger Institute, made the striking discovery while deciphering the genetic code of a series of Leishmania-parasites.

Advanced papillary thyroid cancer patients with BRAFV600E gene mutation at higher risk

Individuals with advanced papillary thyroid cancer (PTC) that are associated with the BRAFV600E gene mutation have a higher risk of recurrent disease and progression to more advanced, poorly differentiated thyroid cancer, according to data presented today at the 81st Annual Meeting of the American Thyroid Association (ATA).

Microglia plays a key role in memory and learning

Immune system cells of the brain, which scavenge pathogens and damaged neurons, are also key players in memory and learning, according to new research by Duke neuroscientists.

Preclinical data from Teva's COPAXONE study on multiple sclerosis

Teva Pharmaceutical Industries Ltd. today announced preclinical data demonstrating reparative and neuroprotective effects of treatment with COPAXONE (glatiramer acetate injection) in experimental autoimmune encephalomyelitis (EAE) models.

Study finds why corticosteroids do not work well for COPD patients

Chronic obstructive pulmonary disease (COPD) leads to persistent inflammation of the airways and is typically managed with corticosteroids, a class of anti-inflammatory medication. However, corticosteroids do not improve survival nor alter the progression of COPD and may reduce lung symptoms as little as 20 percent.

New treatment approach for septic Listeria infection

Research underway at the Trudeau Institute could lead to new treatments for people sickened by Listeria and other sepsis-causing bacteria. Dr. Stephen Smiley's laboratory has published a study in the scientific journal Infection and Immunity that supports a new approach to treating these infections.

Specific MIF gene variant plays a crucial role against bacterial infections

Why are some people prone to severe infections, while others handle them with less difficulty? A new research report appearing online in the FASEB Journal (http://www.fasebj.org) attempts to answer this question by shedding light on the genetic differences that influence our ability to fight off bacterial infections.
