Blood vessel cells are instructed to form tube-like structures
How do blood vessel cells understand that they should organise themselves in tubes and not in layers? A research group from Uppsala University shows for the first time that a special type of "instructor" molecule is needed to accomplish this. These findings, published in the scientific... view more (2008-08-29)

New evidence on addiction to medicines Diazepam has effect on nerve cells in the brain reward system
Addictions to medicines and drugs are thought to develop over a relatively long period of time. The process involves both structural and functional changes in brain nerve cells that are still poorly understood.   view more (2008-08-28)

New role for Natural Killers!
Scientists at the University of York have discovered a new role for a population of white blood cells, which may lead to improved treatments for chronic infections and cancer.   view more (2008-08-28)

Antidepressants need new nerve cells to be effective, UT Southwestern researchers find
Researchers at UT Southwestern Medical Center have discovered in mice that the brain must create new nerve cells for either exercise or antidepressants to reduce depression-like behavior.   view more (2008-08-28)

Cell removal technique could lead to cheaper drugs
Researchers at the University of Edinburgh have pioneered a simple way to remove dead cells from cell cultures used to make protein-based drugs, which are increasingly prescribed to treat a range of illnesses.   view more (2008-08-27)

Potential diabetes treatment selectively kills autoimmune cells from human patients
In experiments using blood cells from human patients with diabetes and other autoimmune disorders, Massachusetts General Hospital (MGH) researchers have confirmed the mechanism behind a potential new therapy for type 1 diabetes.   view more (2008-08-26)

Going from ulcers to cancer
Researchers have uncovered a big clue as to why some of the bacteria that cause stomach ulcers pose a greater risk for serious problems like stomach cancer than others; it turns out these bacteria can exploit the surrounding stomach cells to protect them from the immune system.   view more (2008-08-25)

UAB Anti-Cancer Research Featured in Scientific American
Scientific American magazine focused on two University of Alabama at Birmingham (UAB) Comprehensive Cancer Center researchers in a news story on experimental next-generation anti-cancer therapies.   view more (2008-08-25)

Carnegie Mellon MRI technology that non-invasively locates, quantifies specific cells in the body
Magnetic resonance imaging (MRI) isn't just for capturing detailed images of the body's anatomy. Thanks to novel imaging reagents and technology developed by Carnegie Mellon University scientist Eric Ahrens, MRI can be used to visualize - with "exquisite" specificity - cell populations of... view more (2008-08-22)

Making 'good' fat from muscle and vice versa
A surprise discovery -- that calorie-burning brown fat can be produced experimentally from muscle precursor cells in mice -- raises the prospect of new ways to fight obesity and overweight, say scientists from Dana-Farber Cancer Institute.   view more (2008-08-21)

Killer carbs -- Monash scientist finds the key to overeating as we age
A Monash University scientist has discovered key appetite control cells in the human brain degenerate over time, causing increased hunger and potentially weight-gain as we grow older.   view more (2008-08-21)

Study shows how daughter is different from mother
The mother-daughter relationship can be difficult to understand. Why are the two so different? Now a Northwestern University study shows how this happens. In yeast cells, that is.   view more (2008-08-19)

Personalized immunotherapy to fight HIV/AIDS
For a long time, the main obstacle to creating an AIDS vaccine has been the high genetic variability of the HIV virus. Dr. Jean-Pierre Routy and his team from the Research Institute of the McGill University Health Centre (MUHC), in collaboration with Dr. Rafick Sékaly from the... view more (2008-08-18)

Hydrogels provide scaffolding for growth of bone cells
Hyaluronic hydrogels developed by Carnegie Mellon University researchers may provide a suitable scaffolding to enable bone regeneration. The hydrogels, created by Newell Washburn, Krzysztof Matyjaszewski and Jeffrey Hollinger, have proven to encourage the growth of preosteoblast cells, cells that... view more (2008-08-18)

Lessons from yeast: A possible cure for Parkinson's disease?
Parkinson disease (PD) is a debilitating and lethal neurodegenerative disease, for which there is currently no cure. It is caused by the progressive loss of nerve cells that produce the chemical dopamine and is characterized by the accumulation of abnormal aggregates of a protein called alpha-syn... view more (2008-08-15)

Trapping white blood cells proves novel strategy against chronic viral infections
Seeing disease-fighting white blood cells vanish from the blood usually signals a weakened immune system. But preventing white blood cells' circulation by trapping them in the lymph nodes can help mice get rid of a chronic viral infection, researchers at Yerkes National Primate Research Center and... view more (2008-08-14)

NIH scientists find a novel mechanism that controls the development of autoimmunity
Scientists at the National Institutes of Health (NIH) have found a mechanism in the immune systems of mice that can lead to the development of autoimmune disease when turned off.   view more (2008-08-14)

Protein key to control, growth of blood cells
New research sheds light on the biological events by which stem cells in the bone marrow develop into the broad variety of cells that circulate in the blood. The findings may help improve the success of bone marrow transplants and may lead to better treatments for life-threatening blood diseases.   view more (2008-08-14)

Monash researchers uncover cancer survival secrets
A team of Monash University researchers has uncovered the role of a family of enzymes in the mutation of benign or less aggressive tumours into more aggressive, potentially fatal, cancers in the human body.   view more (2008-08-12)

Childhood brain tumor traced to normal stem cells gone bad
An aggressive childhood brain tumor known as medulloblastoma originates in normal brain "stem" cells that turn malignant when acted on by a known mutant, cancer-causing oncogene, say researchers from Dana-Farber Cancer Institute and the University of California, San Francisco (UCSF).   view more (2008-08-12)

Researchers block damage to fetal brain following maternal alcohol consumption
In a study on fetal alcohol syndrome, researchers were able to prevent the damage that alcohol causes to cells in a key area of the fetal brain by blocking acid sensitive potassium channels and preventing the acidic environment that alcohol produces.   view more (2008-08-11)

Recipe for cell reprogramming adds protein
A drug-like molecule called Wnt can be substituted for the cancer gene c-Myc, one of four genes added to adult cells to reprogram them to an embryonic-stem-cell-like state.   view more (2008-08-07)

Scientists identify possible cause of endometriosis
Endometriosis is a condition whereby patches of the inner lining of the womb appear in parts of the body other than the womb cavity. It can cause severe pain and affects approximately 15% of women of reproductive age. Endometriosis is also associated with infertility, with 50% of infertile women... view more (2008-08-06)

U of M study shows why treatment isn't effective for HIV
University of Minnesota researchers have answered a key question as to why antiretroviral therapy isn't effective in restoring immunity in HIV-infected patients.   view more (2008-08-06)
