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.

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.

UA researchers to study immune response to implanted sensors

A University of Arkansas professor and her colleagues will receive $1.3 million over four years to study the immune response to implanted sensors, such as glucose sensors for diabetics, in hopes of prolonging the life of these important monitoring systems.

Vitamin D plays an essential role in the body's fight against TB

Not just important for building strong bones, an international team of scientists has found that vitamin D also plays an essential role in the body's fight against infections such as tuberculosis.

Aduro initiates CRS-207 and GVAX Pancreas Cancer Vaccine Phase 2 clinical trial

Aduro BioTech, Inc. announces the treatment of the first patient in the Phase 2 pancreatic cancer clinical trial of the sequential administration of two cancer vaccines: Aduro's CRS-207 and GVAX Pancreas Cancer Vaccine.

Scientists discover two HIV variants in cerebrospinal fluid of HAD patients

When the virus that causes AIDS infects the central nervous system, it can lead to the development of a severe neurological disease called HIV- associated dementia.

Lipomannan on TB bacterium's outer cell surface can block TNF production

The bacterium that causes tuberculosis has a unique molecule on its outer cell surface that blocks a key part of the body's defense. New research suggests this represents a novel mechanism in the microbe's evolving efforts to remain hidden from the human immune system.

Researchers discover cell differentiation mechanism

Researchers from the Haematopoietic Differentiation and Stem Cell Biology group at the Centre for Genomic Regulation (CRG), have described one of the mechanisms by which a cell (from the skin, for example) can be converted into another which is completely different.

City cyclists inhale more black carbon than pedestrians

People who cycle through London and other major cities have higher levels of black carbon in their airway cells, experts from the UK have shown.

MDC researchers determine molecular structure of dynamin

Dr. Katja F-lber and Professor Oliver Daumke, structural biologists at the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch, together with researchers from Freie Universit-t (FU) Berlin, have determined the molecular structure of dynamin, a 'wire-puller' that mediates nutrient uptake into the cell.

Immune system uses zinc to destroy tuberculosis bacillus, E. coli

A new natural defense mechanism against infections has been evidenced by an international team led by researchers from CNRS, Inserm, the Institut Pasteur and the Université Paul Sabatier - Toulouse III.

New insight into how nervous system regulates immunity

Scientists have identified a surprising new role for a new type of T cell in the immune system: some of them can be activated by nerves to make a neurotransmitter (acetylcholine) that blocks inflammation. The discovery of these T cells is novel and suggests that it may be possible to treat inflammation and autoimmune diseases by targeting the nerves and the T cells. The study was published this week in Science.

Study finds biological indicators that help explain why obese people develop chronic diseases

UC Davis Health System researchers have discovered biological indicators that help explain why some obese people develop chronic diseases such as diabetes and heart disease, and others do not.

Single-molecule imaging reveals how cells prepare to interact with biochemical signals

Researchers at Harvard Medical School have discovered that structural elements in the cell play a crucial role in organizing the motion of cell-surface receptors, proteins that enable cells to receive signals from other parts of the organism.

Prior parasitic worm infections may complicate TB therapy

Tuberculosis (TB) is a major threat to global health, taking the lives of more than a million people worldwide each year. Its greatest impact is often in the most impoverished places on earth, where patients frequently suffer from multiple chronic illnesses at the same time. In such situations, the question of whether each individual illness might make concurrent illnesses more difficult to treat becomes a critical issue both for specific patients and for general public health.

Researchers demonstrate contribution of Immunoglobulin E to atherogenesis

There is an observed correlation between Immunoglobulin E (IgE) levels atherosclerosis, with twice amount of IgE present in patients with acute myocardial infarction as in patients with stable angina or without coronary heart disease (CHD). Guo-Ping Shi, DSc, Jing Wang, MD, PhD, and colleagues in the Department of Medicine at Brigham and Women's Hospital (BWH), have demonstrated the direct participation of IgE in atherogenesis in a mouse model.
