Potential new strategies for treating obsessive compulsive disorder

Using genetic engineering, researchers have created an obsessive-compulsive disorder (OCD) - like set of behaviors in mice and reversed them with antidepressants and genetic targeting of a key brain circuit.

How the brain produces fever responses during infections

With the finding that fever is produced by the action of a hormone on a specific site in the brain, scientists have answered a key question as to how this adaptive function helps to protect the body during bacterial infection and other types of illness.

Itchy and scratchy gene discovered

Itching for a better anti-itch remedy? Your wish may soon be granted now that scientists at Washington University School of Medicine in St. Louis have identified the first gene for the itch sensation in the central nervous system.

Xenotransplantation from pigs getting closer

Experiments using pigs genetically engineered for compatibility with the human immune system have raised hopes that cross-species transplantation could soon become an option for patients with diabetes and other currently incurable diseases.

Eat a good diet and exercise to live longer

The traditional prescriptions for a healthy life sensible diet, exercise and weight control extend life by reducing signaling through a specific pathway in the brain, according to Howard Hughes Medical Institute researchers who discovered the connection while studying long-lived mice.

Why males show a higher rate of inflammation than females in the same diseases

Production of a protein that promotes inflammation appears to be linked to the higher incidence of liver cancer in men than in women, researchers at the University of California, San Diego (UCSD) School of Medicine have determined in mouse studies.

Protein dysferlin critical for resealing heart muscle cell membranes

During vigorous exercise, heart muscle cells take a beating. In fact, some of those cells rupture, and if not for a repair process capable of resealing cell membranes, those cells would die and cause heart damage (cardiomyopathy).

Faster, less expensive technique for mutating large, non-gene stretches of DNA

Genes account for only 2.5 percent of DNA in the human genetic blueprint, yet diseases can result not only from mutant genes, but from mutations of other DNA that controls genes.

Bone marrow microenvironment can contribute to blood cell disorder

Disorders of blood cells may begin in the biological environment where the cells develop, not just with the cells themselves, according to a study from researchers at the Massachusetts General Hospital (MGH) and the Peter MacCallum Cancer Center (Peter Mac) in Melbourne, Australia.

Molecular motors may speed nutrient processing

Matthew Tyska, Ph.D., recalls being intrigued, from the first day of his postdoctoral fellowship in 1999, with a nearly 30-year-old photograph.

Research reveals a new mechanism of learning in the brain

Mice genetically engineered to lack a single enzyme in their brains are more adept at learning than their normal cousins, and are quicker to figure out that their environment has changed, a team led by researchers at UT Southwestern Medical Center has found.

Scientists develop a more human-like mouse model of cancer

A team led by Dana-Farber Cancer Institute scientists has developed a more human-like mouse model of cancer they say will aid the search for cancer-causing genes and improve the predictive value of laboratory drug testing.

Neuronal pathology of Fragile X syndrome studied

Fragile X syndrome is the most common form of inherited mental retardation, occurring in 1 in 3600 males and 1 in 4000 to 6000 females.

Check and balance for neuron activity provides insight into schizophrenia, seizures

Two genes important for human development and implicated in cancer and schizophrenia also help keep a healthy balance between excitation and inhibition of brain cells, researchers say.

Oncolytic viruses deliver a knockout punch to cancers

New scientific evidence is helping to build a compelling case for oncolytic viruses as a first-line and adjunctive treatment for many cancers.

World's first microRNA knockout mouse

A role for a microRNA in the immune system has been shown by study of one of the world's first microRNA knockout mouse, reported in Science.
