New finding provides researchers with renewable source for macrophages and neutrophils

A new approach to generating large quantities of two types of white blood cells that are critical for destroying invading bacteria, viruses and other pathogens in humans has been developed by researchers at the University of California, San Diego (UCSD) School of Medicine.

Potent induction of chondrocytic differentiation of human adipose-derived adult stem cells by bone morphogenetic protein 6

A novel growth factor significantly improves the ability of specialized stem cells derived from human fat to be transformed into cartilage cells, according to Duke University Medical Center and Pratt School of Engineering researchers.

The Notch effect steers stem cells into cells of the nervous system

Stem cell scientists at the University of Edinburgh have discovered that Notch, a protein first discovered more than 80 years ago in the fruit fly, directs unspecialized embryonic stem cells to become cells of the nervous system.

New model of p53 regulation has important implications for the development of anticancer drugs

Genetically engineered mice convinced scientists at the Salk Institute for Biological Studies that it was time to overhaul widely held beliefs about how a powerful tumor suppressor called p53 is controlled in cells. Their new model of p53 regulation has important implications for the development of anticancer drugs.

Targeted mutations in mice uncover two key molecular events linked to learning

Johns Hopkins researchers have used mouse mutants to define critical steps involved in learning basic motor skills. The study focuses on the behavior of two proteins and the specific steps they take to control a neuron's ability to learn by adapting to signals from other nerve cells.

Lubricin research points to future therapies for osteoarthritis

New evidence to explain how the body's natural joint lubricant prevents the wear and tear that can lead to osteoarthritis has been uncovered by researchers at Duke University's Pratt School of Engineering.The findings may lead to new methods for treating arthritis, the researchers said.

Losartan can prevent progression of Marfan syndrome

A commonly prescribed blood pressure medication may provide the first ray of hope in preventing potentially deadly complications of Marfan syndrome, a genetic disease that weakens the structural meshwork of blood vessels.

Researchers engineer cells in the eye to be light sensitive that were not before

In an experiment that could offer a new pathway to restoring vision in people with inherited retinal degeneration, researchers have engineered cells in the eye to be light sensitive that were not before.

Multi-site vaccinations could protect against all four dengue viruses

An innovative new study explains, for the first time, the failure of previous attempts to vaccinate against the four known Dengue viruses, and it suggests a very simple solution - injecting the four vaccines simultaneously at different locations on the body.

Gene key to infection-fighting immune cells identified

Every time the human body encounters a virus, bacteria or other infectious agent, immune cells called B-lymphocytes multiply in lymph nodes and then swing into action to fight off the intruders.

Malaria, mosquitoes and man - breaking a deadly cycle

Malaria kills a child every thirty seconds in Sub-Saharan Africa, according to recent estimates. It is a huge problem currently threatening over 40% of the world’s population and still on the increase.

Weill Cornell researchers identify tumor-suppressor gene important to diffuse large B-cell lymphomas

Inactivation of a "tumor suppressor" gene could be a major cause of a class of blood cancers called diffuse large B-cell lymphomas, reports a team of researchers at the Weill Medical College of Cornell University.

Researchers find environmentally friendly ways to produce more Taxol

As the effective cancer-treatment drug Taxol enters its next generation, Michigan State University announces discoveries which point to both environmentally friendly ways to produce more Taxol, and ultimately innovations to produce a more potent second-generation drug.

Will we ever eat pigs genetically engineered to give us healthy fats?

Researchers in the U.S. have created pigs that produce omega-3 fatty acids, which are believed to improve heart function and help reduce the risks for heart disease.

Successful cell engineering may prevent bovine spongiform encephalopathy (BSE)

Researchers at Texas A&M University have successfully "knocked down" the expression of possible disease-causing genes in a cloned goat fetus, perhaps paving the way for breeding disease resistance in other animals, even those genes that might cause bovine spongiform encephalopathy (BSE), commonly known as Mad Cow Disease.

Protein complex in brain may be key to Alzheimer's

Scientists in the U.S. say they have discovered a substance in the brain of mice that causes memory loss; they believe the discovery gives drug developers a target for creating drugs to treat memory loss in people with dementia.

Chillies send prostate cancer cells on a suicidal path

According to new research the very ingredient which makes chilli peppers so hot, also affects prostate cancer cells and makes them commit suicide.

Researchers find a way to make plants produce more antigens needed for vaccines

Scientists have developed a new kind of molecule which they believe could ultimately lead to the development of a vaccine against HIV using genetically modified tobacco.

Scientists exploit novel route to reverse enlarged hearts in obese mice

Working on genetically engineered obese mice with seriously thickened hearts, a condition call cardiac hypertrophy, scientists at Johns Hopkins have used a nerve protection and growth factor on the heart to mimic the activity of the brain hormone leptin, dramatically reducing the size of the heart muscle.

Thalidomide, Lenalidomide show promise against Lou Gehrig's disease

New animal research suggests that two well-studied drugs, thalidomide and its derivative, lenalidomide, might extend the survival of patients with the neurological disorder amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease.
