Lung injury is a common cause of death among patients with pneumonia, sepsis or trauma and in those who have had lung transplants. The damage often occurs suddenly and can cause life-threatening breathing problems and rapid lung failure. There are no effective treatments. Patients usually are put on ventilators to give their lungs a chance to heal, but there is little else doctors can do but wait and hope for the best. Now, researchers at Washington University School of Medicine in St. Louis...

Virginia Commonwealth University School of Medicine researchers have found that a significant increase of an enzyme in the blood vessels of pregnant women with preeclampsia may explain some of the symptoms associated with the condition, including hypertension, swelling and protein in the urine. The findings could lead to a treatment for pregnant women with preeclampsia, which is one of the most significant health problems in pregnancy and a leading cause worldwide of both premature delivery...

New research by scientists at the University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences reveals that the immune system has an effective backup plan to protect the body from infection when the "master regulator" of the body's innate immune system fails. The study appears in the December 19 online issue of the journal Nature Immunology. The innate immune system defends the body against infections caused by bacteria and viruses, but also...

Studies in mice reveal how bacteria hamper frontline defense cells WHAT: Researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have determined a key mechanism by which Bacillus anthracis bacteria initiate anthrax infection despite being greatly outnumbered by immune system scavenger cells. The finding, made by studying genetically modified mice, adds new detail to the picture of early-stage anthrax infection and supports...

White blood cells called neutrophils are part of the body's first line of defense against bacterial infection. Neutrophils are recruited from the bloodstream to infected tissues where they release powerful chemicals that kill bacteria and amplify the immune response. These cells function as first responders at the scene of infection and often have a short life span. As a result, new neutrophils are produced continuously from stem cells in the bone marrow. Previous research has suggested that...

A new study reveals that two enzymes help immune cells deploy pathogen-killing traps by unraveling and using the chromatin (DNA and its associated proteins) contained in the cells' nuclei to form defensive webs. The study appears online on October 25 in The Journal of Cell Biology (www.jcb.org). Neutrophils, the most common type of white blood cells, are difficult to study because they live for only about six hours. So Arturo Zychlinsky and colleagues, from the Max Planck Institute for...

research published in Science Researchers at the University of Calgary Faculty of Medicine are using an innovative new imaging technique to study how white blood cells (called neutrophils) respond to inflammation, and have revealed new targets to inhibit the response. When the body is invaded by infection, the immune system counters by generating inflammation with deployment of white blood cells to the site of danger to kill invading bacteria. However, inappropriate inflammation occurs in the...

Cigarette smoke shuts off a key enzyme in airways that regulates the body's response to inflammation, according to findings from the University of Alabama at Birmingham published online today at Science Express. The UAB researchers say smoke inhibits the enzyme, called Leukotriene A4 Hydrolase (LTA4H), causing it to fail in its job of shutting down white blood cells following a successful response to inflammation. The team says the research study identified a previously unknown substrate of...

A study published today in the journal Science shows how our bodies try to minimise potential 'collateral damage' caused by our immune system when fighting infection. The research may also provide new clues to why cigarette smoke is a significant risk factor for developing diseases of the lung such as chronic bronchitis and emphysema. When bacteria or viruses enter the body, our immune system fights back to neutralise any danger. One of the key 'soldiers' working for the immune system is a...
