DNA of good bacteria drives intestinal response to infection

A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection.

A DNA-based vaccine shows promise against avian flu

Though it has fallen from the headlines, a global pandemic caused by bird flu still has the United States' Centers for Disease Control and Prevention on high alert. Yet, to date, the only vaccines that have proven even semi-effective are produced in chicken eggs, take five to six months to prepare and act against a single variant of the H5N1 virus, which mutates incredibly quickly.

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.

Immune system hurts as well as fights cancer - discovery could lead to new cancer treatments with fewer side effects

Researchers at the University of Pennsylvania School of Medicine have found that some proteins of the immune system can promote tumor growth.

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.

Pain is not a symptom of arthritis, pain causes arthritis

Pain is more than a symptom of osteoarthritis, it is an inherent and damaging part of the disease itself, according to a study published today in journal Arthritis and Rheumatism.

Existing anti-obesity drugs may be effective against flu, hepatitis and HIV

Viruses dramatically increase cellular metabolism, and existing anti-obesity drugs may represent a new way to block these metabolic changes and inhibit viral infection, according to a study published today in the journal Nature Biotechnology.

New way to control protein activity could lead to cancer therapies

Investigators at the Stanford University School of Medicine have found a way to quickly and reversibly fine-tune the activity of individual proteins in cells and living mammals, providing a powerful new laboratory tool for identifying - more precisely than ever before - the functions of different proteins.

Hybrid nanoparticles image and treat tumors

By combining a magnetic nanoparticle, a fluorescent quantum dot, and an anticancer drug within a lipid-based nanoparticle, a multi-institutional research team headed by members of the National Cancer Institute's (NCI) Alliance for Nanotechnology in Cancer has created a single agent that can image and treat tumors. In addition, this new nanoparticle is able to avoid detection by the immune system, enabling the particle to remain in the body for extended periods of time.

Researchers investigate impact of stress on police officers' physical and mental health

Policing is dangerous work, and the danger lurks not on the streets alone. The pressures of law enforcement put officers at risk for high blood pressure, insomnia, increased levels of destructive stress hormones, heart problems, post-traumatic stress disorder (PTSD) and suicide, University at Buffalo researchers have found through a decade of studies of police officers.

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.

New technology to analyse human cells

A new technology which enables scientists to identify proteins by making a map of the energy flow inside the protein is revealed in Proceedings of the National Academy of Sciences (PNAS) journal.

Coles contaminated chicken recalled in four states

The discovery that packs of pre-sliced chicken sold by the supermarket chain Coles were contaminated with listeria, has prompted a recall of the product from stores in New South Wales, South Australia, Victoria and Queensland and Coles Online.

Exposure to bacteria might prevent type I diabetes

Researchers from Yale University and the University of Chicago have found a startling illustration of the potential for microbes to prevent disease - they found that mice exposed to common stomach bacteria were protected against the development of type I diabetes.

Research provides new insights into how cells accessorize their proteins

St. Jude Children's Research Hospital investigators have gained new insight into how the cell's vast array of proteins would instantly be reduced to a confusion of lethally malfunctioning molecules without a system for proteins to "accessorize" in order to regulate their function.

Flies reveal immune cell response to tumour and tissue damage

Research with fruit flies has revealed more in common between simple cuts and scratches and the growth of tumours than might have been expected.

Combo of flu shot and COLD-FX cuts cold and flu by a third

A new study has shown the benefit of annual flu vaccinations for seniors along with Canada's top cold and flu-fighting product COLD-FX.

Breast cancer vaccine could protect against aggressive HER2-positive breast tumours

Women with a certain type of breast cancer have been given hope in the form of a vaccine which promises to eliminate the cancer tumours.

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.

FDA grants approval to Talecris Biotherapeutics for Gamunex for neurological disorder CIDP

Talecris Biotherapeutics, Inc. announced today the U.S. Food and Drug Administration (FDA) has granted approval for Gamunex (Immune Globulin Intravenous [Human], 10% Caprylate/Chromatography Purified) as a treatment for chronic inflammatory demyelinating polyneuropathy (CIDP). CIDP is a debilitating neurological disorder that results in muscle weakness and fatigue, which can lead to severe impairment of motor skills.
