Two studies reveal how plague disables immune system

Two studies by researchers at the University of Chicago show how the bacteria that cause the plague manage to outsmart the immune system and how, by slightly altering one of the microbe's tools, the researchers produced what may be the first safe and effective vaccine.

New way to fight antibiotic-resistant Staphylococcus infections

Researchers at the University of California, San Diego School of Medicine and Children’s Hospital and Health Center, San Diego have discovered that "Staph" bacteria use a protective golden armor to ward off the immune system, a finding with the potential to lead to new treatments for serious infections now increasingly resistant to standard antibiotics.

White blood cell called a neutrophil appears to be crucial to abdominal aortic aneurysm formation

Each year, 200,000 Americans find out that the largest blood vessel in their body, the aorta, may burst open at any time. About 20,000 die suddenly from such a rupture. And another 36,000 have surgery to repair or replace the swelling section of aorta before time runs out.

Bling Bling bacteria more dangerous!

Researchers in the U.S. have uncovered the interesting fact that gold-colored bacteria appear to cause more disease than colorless strains.

Molecules that give certain bugs their color also help them resist attack by immune cells called neutrophils

A new study in the July 18 issue of The Journal of Experimental Medicine shows that gold-colored bacteria are more harmful than their unpigmented relatives.

Simple analysis of a bone marrow transplant patient's oral rinse indicates whether infection will develop

Simple analysis of a bone marrow transplant patient's oral rinse can give medical personnel a quick indication of the transplant's effectiveness and predict whether an infection will develop, says a University of Toronto researcher.

Enzyme known as cathepsin G may be a target for anti-inflammatory treatments

The finding by researchers at Washington University School of Medicine in St. Louis shows that an enzyme known as cathepsin G regulates the ability of immune cells known as neutrophils to secrete chemicals that attract other immune cells and start the local inflammatory process. Over time, the excessive accumulation of immune cells can lead to tissue and cartilage damage in joints, causing pain and limiting mobility.

European approval of Temodal (temozolomide) capsules for treatment of glioblastoma multiforme

Schering-Plough announced today that the European Commission has granted approval of Temodal (temozolomide) Capsules for first-line use for the treatment of patients with newly diagnosed glioblastoma multiforme (GBM), the most common and aggressive form of primary brain cancer.

Research findings suggest new treatment strategies for patients with cystic fibrosis

Cells sent to fight infections in the lungs of cystic fibrosis patients actually enhance the development of permanent bacterial infections, according to researchers at National Jewish Medical and Research Center.

Stimulating innate immunity helps ease Crohn's disease symptoms

Like throwing oil on a fire or prescribing a high cholesterol diet for heart patients, gastroenterologists traditionally have believed that it would not be a good idea to stoke up the body's immune system to treat Crohn's disease.

Routine, inexpensive blood test sharpens heart disease risk predictions

Routine measurements of white blood cell counts that provide a ratio of neutrophils to lymphocytes may offer a simple and low-cost way to refine predictions of heart attack or death, according to a new study in the May 17, 2005, issue of the Journal of the American College of Cardiology.

Disabling gene defuses rheumatoid arthritis in mice

Scientists studying mice have identified a gene that allows immune cells known as neutrophils to protect themselves from the inflammatory chemicals they secrete.

Neutrophils dictate whether our immune system will permit or prevent bacterial infections

New research on a bacterium that can survive encounters with specific immune system cells has strengthened scientists' belief that these plentiful white blood cells, known as neutrophils, dictate whether our immune system will permit or prevent bacterial infections.

New prognostic markers help identify risk of relapse

A recently completed clinical study has found new prognostic markers that may help clinicians identify those children with leukaemia who are at high risk of relapse and are most in need of intensified treatment to improve their chance of survival.

Airway inflammation boosts infarction damage

Epidemiological studies show that the incidence of cardiovascular disease (CVD) complications are increased in long standing cases of asthma. Historically, the complications are often attributed to the chronic drug therapy used to treat asthma.

Novel protein marker for early diagnosis of kidney failure

Researchers have found a novel protein marker that can give a rapid and early diagnosis of kidney failure in children undergoing heart surgery, reporting their results in this week’s issue of The Lancet.

Process for disposal of dying neutrophils actively linked to neutrophil production

New research identifies a critical inhibitory step that is a key component of the feedback circuit regulating the balance between neutrophil production and destruction.

How does the body keep the number of neutrophils produced constant in the blood?

Every day, the human body manufactures and destroys about 100 billion neutrophils- the most common type of white blood cell and one of the most highly-produced cells. Neutrophils live about eight hours, are bacteria-eaters and are a key component of the immune system. Without them, the body can be subject to life-threatening infection.

Genomic analysis may one day be a primary diagnostic tool for physicians deciding on a course of treatment for trauma

The researchers showed that state-of-the-art techniques for rapidly analyzing changes in activity of all human genes will likely produce useful insights into the health of critically ill patients. The findings, which are available online and will be published in the March 29 issue of the Proceedings of the National Academy of Sciences, make it possible for physicians to begin answering important questions about critical care through genomic analysis.

Turning point in the history of preterm labor diagnosis

A combination of four proteins that result from inflammation and infection and lead to premature birth can be rapidly and accurately detected in the amniotic fluid of pregnant women using proteomics technology, Yale researchers report in two studies in the February issue of British Journal of Obstetrics and Gynecology.
