Wistar scientists find key to keeping killer T cells in prime shape for fighting infection, cancer
Like tuning a violin to produce strong, elegant notes, researchers at The Wistar Institute have found multiple receptors on the outside of the body's killer immune system cells which they believe can be selectively targeted to keep the cells in superb infection- and disease-fighting condition.   view more (2008-12-01)

Cancer drugs my build and not tear down blood vessels
Scientists have thought that one way to foil a tumor from generating blood vessels to feed its growth - a process called angiogenesis - was by creating drugs aimed at stopping a key vessel growth-promoting protein. But now the opposite seems to be true.   view more (2008-11-10)

First comprehensive genomic study of common cold reveals new treatment targets
Today, scientists from Procter & Gamble (P&G), the University of Calgary and the University of Virginia announced results from the first study to examine the entire human genome's response to the most common cold virus, human rhinovirus.   view more (2008-10-27)

Avian flu threat: New approach needed
As the first globally co-ordinated plan for the planet's gravest health threats is hatched by government ministers from around the world this weekend, a new report sets out a 10-point plan for this new, globalised approach to infectious diseases such as avian flu.   view more (2008-10-23)

Scripps research scientists enhance immune system attacks on cancer
In an Early Edition issue of the Proceedings of the National Academy of Sciences (PNAS) published online on October 20, 2008, the scientists describe how they used multiple tactics to rev up both innate and adaptive immunity to enhance the body's ability to fight cancer.   view more (2008-10-22)

Researchers identify genetic switch critical for cell survival in hypoxia
Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive.   view more (2008-10-17)

Brown Scientist Finds Coastal Dead Zones May Benefit Some Species
Coastal dead zones, an increasing concern to ecologists, the fishing industry and the public, may not be as devoid of life after all. A Brown scientist has found that dead zones do indeed support marine life, and that at least one commercially valuable clam actually benefits from oxygen-depleted... view more (2008-10-15)

Response to immune protein determines pathology of multiple sclerosis
New research may help reveal why different parts of the brain can come under attack in patients with multiple sclerosis (MS). According to a new study in mice with an MS-like disease, the brain's response to a protein produced by invading T cells dictates whether it's the spinal cord or cerebellum... view more (2008-10-14)

RNA molecules, delivery system improve vaccine responses, effectiveness
A novel delivery system that could lead to more efficient and more disease-specific vaccines against infectious diseases has been developed by biomedical engineers at The University of Texas at Austin.   view more (2008-10-09)

MSU scientists find new gene that helps plants beat the heat
Michigan State University plant scientists have discovered another piece of the genetic puzzle that controls how plants respond to high temperatures. That may allow plant breeders to create new varieties of crops that flourish in warmer, drier climates.   view more (2008-10-07)

Millisecond brain signals predict response to fast-acting antidepressant
Images of the brain's fastest signals reveal an electromagnetic marker that predicts a patient's response to a fast-acting antidepressant, researchers have discovered.   view more (2008-10-03)

Rethinking Who Should Be Considered 'Essential' During a Pandemic Flu Outbreak
Not only are doctors, nurses, and firefighters essential during a severe pandemic influenza outbreak. So, too, are truck drivers, communications personnel, and utility workers.   view more (2008-10-03)

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.   view more (2008-10-03)

Steroids Not as Effective in Obese Asthma Patients
Researchers at National Jewish Health have shown that glucocorticoids, the primary controller medication for asthma, are 40 percent less effective in overweight and obese asthma patients than in those of normal weight.   view more (2008-09-17)

Early parenting plays key role in infants' physiological response to stress
In infancy, genes are the key influence on a child's ability to deal with stress. But as early as 6 months of age, parenting plays an important role in changing the impact of genes that may put infants at risk for responding poorly to stress.   view more (2008-09-16)

Individuals vary their immune response according to age, sex and the costs
Is it always good to respond maximally when pathogens or disease strike, or should individuals vary their immune response to balance immediate and future costs?   view more (2008-09-11)

Physicists harness effects of disorder in magnetic sensors
University of Chicago scientists have discovered how to make magnetic sensors capable of operating at the high temperatures that ceramic engines in cars and aircraft of the future will require.   view more (2008-09-10)

A potential approach to treatment of hepatitis B virus infection
Eukaryotic cells employ multiple strategies of checkpoint signaling and DNA repair mechanisms to monitor and repair damaged DNA.   view more (2008-09-10)

Previous claims of siRNA therapeutic effects called into question by report in human gene therapy
The many recent reports documenting the therapeutic efficacy of short interfering RNAs (siRNAs) in animal models of human disease may actually be describing non-specific therapeutic effects related to the ability of siRNA to activate an immune response, according to a paper in the September 2008... view more (2008-09-03)

New study shows health benefits of probiotic could extend to the entire body
Data from a recent study demonstrate the anti-inflammatory and pathogen protection benefits of Bifidobacterium infantis 35624 a probiotic bacterial strain of human origin.   view more (2008-08-25)

Accumulated bits of a cell's own DNA can trigger autoimmune disease
A security system wired within every cell to detect the presence of rogue viral DNA can sometimes go awry, triggering an autoimmune response to single-stranded bits of the cell's own DNA, according to a report in the August 22nd issue of the journal Cell, a Cell Press publication.   view more (2008-08-22)

To protect against liver disease, body puts cells 'under arrest'
A stable form of cell-cycle arrest known to offer potent protection against cancer also limits liver fibrosis, a condition characterized by an excess of fibrous tissue, according to a new report in the August 22nd Cell, a Cell Press publication.   view more (2008-08-22)

Infection Blocks Lung's Protective Response Against Tobacco Smoke
An infection that often goes undetected can block the lung's natural protective response against tobacco smoke, according to researchers at National Jewish Health.   view more (2008-08-20)

Study shows continued spread of 'dead zones'
A global study led by Professor Robert Diaz of the Virginia Institute of Marine Science, College of William and Mary, shows that the number of "dead zones"-areas of seafloor with too little oxygen for most marine life-has increased by a third between 1995 and 2007.   view more (2008-08-15)

Sensitivity to antidepressants linked with TrkB-mediated neural proliferation
Scientists have unveiled a functional link between production of new neurons and the effectiveness of antidepressants (ADs) in an animal model. The study, published by Cell Press in the August 14 issue of the journal Neuron, provides exciting insight into a mechanism that might underlie a poor... view more (2008-08-14)
