New gene shows way for autoimmune disease

A new gene suspected to contribute to autoimmune diseases such as type 1 diabetes and lupus - a condition in which the body’s own immune system attacks organs such as the kidneys and skin - has been discovered by Australian National University (ANU) immunologists.

Sickle cell protects against malari

In this month's issue of the open access journal PLoS Medicine, Dr. Thomas N. Williams and colleagues from Kilifi, Kenya, show that the protection against malaria given by carrying the gene for sickle cell haemoglobin may involve the immune system.

Bioniche Life Sciences granted European patent

Bioniche Life Sciences has announced that it has had another patent granted on its core technology: Mycobacterial Cell Wall-DNA Complex (MCC). The European Patent Organization (EPO) granted the patent: - "Composition and Method for Inducing Apoptosis in Prostate Cancer Cells" (EPO1165106)

Leprosy microbes lead scientists to immune discovery

With the unusual opportunity that human leprosy infections provide for study of human immune responses, scientists have discovered how the body's early warning system prompts a rapid immune response by two separate armies of defensive cells.

Fluorescence device to diagnose atherosclerosis and tumors

In a presentation at the Conference on Lasers and Electro-Optics (CLEO), researchers from Cedars-Sinai Medical Center's Biophotonics Research and Technology Development Laboratory described recent progress on a device that stimulates, collects and measures light emissions from body tissues to diagnose critical atherosclerotic plaques (vulnerable plaques) and aggressive brain tumors.

Is winter flu worse because of exercise-induced 'window of susceptibility'?

When you exercise or work outside in winter, that dry feeling at the back of your throat indicates the cold air has irritated your throat. Racehorses share a similar experience: exercising in below-freezing air causes mild airway injury.

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.

Research provides roadmap for the development of human therapies for cytomegalovirus (CMV)

McGill University Health Centre (MUHC) researchers have defined genetic resistance to the widespread virus, cytomegalovirus (CMV)--a member of the viral group that causes some of the world's most prevalent diseases, such as herpes, chicken pox and mononucleosis.

Female lung transplant recipients more likely to suffer from primary graft dysfunction

Female lung transplant recipients are significantly more likely to suffer from a type of injury to the transplanted lung called primary graft dysfunction than male lung transplant patients, according to a study presented at the American Thoracic Society International Conference.

Study shows using expanded critera donors is safe

Patients who had received livers from hepatitis B virus core antibody (HBcAb) positive (indicates prior exposure to hepatitis B) and/or hepatitis C virus (HCV) positive donors had similar graft and patient survival compared to patients who received HBcAb negative or HCV negative livers, according to a study by the University of Pittsburgh's Thomas E. Starzl Transplantation Institute.

Six deaths in transplant patients now linked to rodent virus

In the latest news on the subject, experts now believe they can link at least six deaths of organ transplant patients to a rodent virus, which raises questions about whether others may have gone undetected and whether the germ also could spread through blood transfusions.

Cyclophosphamide may be a possible therapy for scleroderma

A drug that suppresses the immune system and reduces inflammation has been shown to be effective in treating lung disease associated with the devastating connective tissue disease scleroderma, according to results presented at the American Thoracic Society International Conference on May 23.

Virus from rodents kills three transplant recipients

Three transplant patients have died as a result of receiving an organ from a donor who had unknowingly been infected with a common rodent virus. A fourth patient who received a kidney from the organ donor is recovering.

Anti-inflammatory protein annexin 1 may protect patients from the detrimental effects of severe inflammatory response syndrome

Severe inflammatory response syndrome, or SIRS, occurs when the body's response to an overwhelming infection becomes uncontrolled. The very immune response meant to clear the pathogen and its toxins actually causes damage to the host's own tissues when it goes into overdrive, releasing too many immune signals.

Narcotic medications can safely and effectively ease severe, chronic pain in older people

Narcotic medications can safely and effectively ease severe, chronic pain in older people with little risk that these patients will seek ever-increasing doses, UCSF medical scientists have found. Younger patients, however, are likely to want to rapidly increase their medication dose, the researchers found, posing serious potential health consequences.

Vietnam reports another bird flu death

A death of a man from bird flu in Vietnam's Northern Province, has brought the total deaths in the country since late 2003 to 38.

Scientists show nuclear protein Ezh2 helps establish previously unknown signaling pathway in cells

Since 2001, scientists have wrestled with the discovery that there are fewer genes in humans than biological processes linked to those genes over the course of a human lifespan. One way to understand genetically coded events is by studying epigenetics, the regulation and heritability of genes at a cellular level due to molecular changes to the many proteins (called histones) that package DNA in a cell's nucleus.

Gene keeps neural cells on correct developmental path

Embryonic stem cells with identical genomes grow into distinctive tissues, such as heart, bone, and brain. At one time, scientists believed the differences among cell types arose from various sets of genes switched on inside developing cells.

Russian team tests new polymeric coating for vascular stents

A group of researchers of the Institute of Biophysics (Russian Academy of Sciences), Krasnoyarsk regional clinical hospital and Krasnoyarsk regional department of morbid anatomy under the guidance of .I. Gitelzon, Academician of Russian Academy of Sciences, have tested characteristics of a new polymeric coating for vascular stents.

Allergies increase risk for corneal transplant rejection

Corneal transplant patients who suffer from eye allergies are at a significantly higher risk of transplant failure than those without allergies, UT Southwestern Medical Center researchers have shown.
