- Factor key to severity of community-associated methicillin-resistant staph infections identified
11-11-2007 · EurekAlert!
Newly described proteins in drug-resistant strains of the Staphylococcus aureus bacterium attract and then destroy protective human white blood cells -- a key process ensuring that S. aureus survives and causes severe disease, according to scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.

- Scientists discover how cancer may take hold
09-24-2007 · EurekAlert!
A team, led by researchers at the Carnegie Institution, has found a key biochemical cycle that suppresses the immune response, thereby allowing cancer cells to multiply unabated. The research shows how the biomolecules responsible for healthy T cells, the body's first defenders against hostile invaders, are quashed, permitting the invading cancer to spread. The same cycle could also be involved in autoimmune diseases such as multiple sclerosis.

- Study reveals how stem cells decide to become either skeletal or smooth muscle
10-10-2007 · EurekAlert!
Researchers have discovered that a key protein controls how stem cells 'choose' to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels. The results suggest new ways to treat atherosclerosis and cancer, diseases that involve the creation of new blood vessels from stem cell reserves that would otherwise replace worn out skeletal muscle.

- UCSD researchers discover internal compass of immune cell
12-14-2006 · EurekAlert!
Researchers at the UCSD School of Medicine have discovered how neutrophils -- specialized white blood cells that play key roles in inflammation and in the body's immune defense against bacteria -- navigate to sites of infection and inflammation. These findings could potentially lead to new treatments for serious infections and inflammatory diseases in patients.

- Pregnancy hormone key to repairing nerve cell damage
02-20-2007 · EurekAlert!
The mystery of why multiple sclerosis (MS) tends to go into remission while women are pregnant may be the secret to overcoming the devastating neurodegenerative disease, according to University of Calgary researchers who have shown that the pregnancy-related hormone prolactin is responsible for rebuilding the protective coating around nerve cells. New paper to be published in Feb. 21 edition of the Journal of Neuroscience

- Existence of muscle-building stem cells points to regenerative therapies for muscular disease
05-31-2007 · EurekAlert!
A new report in the June 1 issue of the journal Cell, a publication of Cell Press, confirms the existence of some apparently uncommitted stem cells amongst cells responsible for generating the bulging biceps of body builders and the rippling abs of fitness buffs. The findings could lead to new muscle-regenerating therapies -- including cell transplantation regimens and stem cell-replenishing drugs -- for people with various muscle-wasting diseases, including muscular dystrophies.

- Neural stem cell study reveals mechanism that may play role in cancer
09-04-2007 · EurekAlert!
In the dynamic world of the developing brain, neural stem cells give rise to neurons deep within the brain’s fluid-filled ventricles. These newborn neurons then migrate along the stem cell fibers up to the neocortex, the seat of higher cognitive functions. Now, scientists have discovered a key mechanism of this migration -- one that may also play an important role in other developmental processes and diseases, including cancer.

- Brown researchers make major signal transduction discovery
10-04-2007 · EurekAlert!
How cells sense and respond to chemical messages -- a process known as signal transduction -- is a fundamental force in biology, controlling key processes such as cell growth and immune response. Now researchers from the Warren Alpert Medical School of Brown University and Rhode Island Hospital report a significant discovery in the field of signal transduction that could provide a new target for drugs that fight cancer, HIV and diseases. Results are published in Cell.

- Genetic 'Roadmap' Charts Links Between Drugs And Human Disease
10-02-2006 · ScienceDaily
A research team led by scientists at the Broad Institute of MIT and Harvard developed a new kind of genetic "roadmap" that can connect human diseases with potential drugs to treat them, as well as predict how new drugs work in human cells. Called the "Connectivity Map," the tool and its uses are described in the September 29 issue of Science and in separate publications in the September 28 immediate early edition of Cancer Cell.

- Researchers hot on the trail of brain cell degeneration
03-19-2007 · EurekAlert!
A research team headed by Academy Research Fellow Michael Courtney has identified a new molecular pathway in neurons. The pathway is a factor in the degeneration of brain cells, which in turn plays an important role in neurological conditions and diseases, such as Alzheimer's disease, epilepsy and stroke.
