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.

VIA Pharmaceuticals announces results of phase 2 trials of VIA-2291 in cardiovascular disease

Newly discovered protein may help explain tuberculosis' resiliency

Weill Cornell scientists have located a protein produced by the tuberculosis bacterium that may tell researchers more about how the invader lives so resiliently inside of the body.

Proteomics provides clues to how tuberculosis thwarts the immune system

A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases.

New therapeutic target for inflammatory disorders

Researchers at Hospital for Special Surgery have identified a potential new therapeutic target that could be used to treat inflammatory disorders, such as rheumatoid arthritis.

Parasites that live inside cells use loophole to thwart immune system

St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide.

Parasites that live inside cells use loophole to thwart immune system

St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide. The researchers found that the microbes block nitric oxide production by subverting the biochemical machinery used by immune cells called macrophages to produce the chemical.

Persistent bacterial infection exploits killing machinery of immune cells

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

Tuberculosis bacterium uses its sugar coat to sweeten its chances of living in lungs

Common strains of tuberculosis-causing bacteria have hijacked the human body's immune response to play tricks on cells in the lungs, scientists say.

Multiple sclerosis patients have higher spinal fluid levels of suspicious immune molecule

A protein that helps keep immune cells quiet is more abundant in the spinal fluid of patients with multiple sclerosis (MS), further boosting suspicion that the protein, TREM-2, may be an important contributor to the disease.

Study of 'Big Eaters' could lead to better asthma treatments

A new study into the role of a particular immune cell in the lungs could lead to better treatments for the 5 million people in the UK affected by asthma.

Study identifies immune response that enables TB bacteria to multiply, provides new target for TB drugs

Researchers have identified an immune system response to tuberculosis that enables TB bacteria to spread through the lungs, providing a new target for TB drug development, according to a study published Sunday in Nature Immunology, AFP/Washington Times reports.

Catching the blood cell bus gives fatal yeast infection a clean getaway

Yeast fungus cells that kill thousands of AIDS patients every year escape detection by our bodies' defences by hiding inside our own defence cells, and hitch a ride through our systems before attacking and spreading, scientists heard today (Tuesday 9 September 2008) at the Society for General Microbiology's 163rd meeting being held this week at Trinity College, Dublin.

MorphoSys announces publication of first MOR103 data

MorphoSys AG announced today the publication of a first data package for its most advanced proprietary drug development program MOR103, a fully human HuCAL antibody directed against GM-CSF, in the journal "Molecular Immunology".

Issues on cholesterol: diet, statins and genetics

Genetic lipoprotein disorders are frequently seen in patients with premature coronary artery disease (CAD). An example of strong genetic predisposition is the disorder: familial hypercholesterolemia, where a single gene defect (the low density lipoprotein receptor) contributes to most of the familial expression of CAD.

Researchers find Leishmaniasis parasites evade death by exploiting the immune response to sand fly bites

Cutaneous leishmaniasis, a disease characterized by painful skin ulcers, occurs when the parasite Leishmania major, or a related species, is transmitted to a mammalian host by the bite of an infected sand fly.

Discovery of new anatomical path through which the brain and spleen communicate

In a major step in understanding how the nervous system and the immune system interact, scientists at The Feinstein Institute for Medical Research have identified a new anatomical path through which the brain and the spleen communicate.

Nanocantilevers image nanoparticles in cells

Borrowing from a Nobel Prize-winning technique credited with starting the nanotechnology revolution, a team of researchers from Oak Ridge National Laboratory (ORNL) and Northwestern University's Nanomaterials for Cancer Diagnostics and Therapeutics has developed a method for imaging nanoparticles inside of cells.

Discovery of new function for an old enzyme in sialidosis

The lack of a single protein usually thought of as a run-of-the-mill enzyme that helps to recycle molecules in cells causes an incurable and often fatal disease of children, according to St. Jude Children's Research Hospital investigators.
