Cellular metabolism of immune cells protect against viral infections and tumours

New research demonstrates that the cellular metabolism of certain immune cells is closely linked to their function, which includes protecting against viral infections and the development of tumours.

Researchers demonstrate significance of two proteins in nerve cell development

The study conducted by Prof. Frank Bradke's team provides indications on brain development and about the causes of diseases of the nervous system. The results have now been published in "Neuron".

Autism genome not shy about tinkering with important genes

An international team, led by researchers from the University of California, San Diego School of Medicine, has discovered that "random" mutations in the genome are not quite so random after all. Their study, to be published in the journal Cell on December 21, shows that the DNA sequence in some regions of the human genome is quite volatile and can mutate ten times more frequently than the rest of the genome. Genes that are linked to autism and a variety of other disorders have a particularly strong tendency to mutate.

Novel testing reaction based on magnetic resonance data

In their quest for new agents, pharmaceutical researchers test millions of substances all over the world. They like using color-forming reactions to identify new molecules. However, in intensively colored solutions or in the case of mixtures with multiple substances these tests fail.

Towards imaging biological processes in action at the atomic level

If the key to winning battles is knowing both your enemy and yourself, then scientists are now well on their way toward becoming the Sun Tzus of medicine by taking a giant step toward a priceless advantage - the ability to see the soldiers in action on the battlefield.

Molecule imitating a virus may trigger inappropriate immune response

Why would our immune system turn against our own cells? This is the question that the combined Inserm/CNRS/ Pierre and Marie Curie University/Association Institut de Myologie have strived to answer in their "Therapies for diseases of striated muscle", concentrating in particular on the auto-immune disease known as myasthenia gravis.

New insight into structure of Cathepsin B protein

Using the world's most powerful X-ray free-electron laser, an international team of researchers, including scientists of the Max Planck Institute for Medical Research in Heidelberg, has obtained new insight into the structure of a medicinally important protein that may serve as a blueprint for the development of drugs to fight sleeping sickness. Science magazine have chosen the experimental study as one of the top ten scientific breakthroughs of the year.

Novel virus-based gene therapy holds promise for Canavan disease

Research led by Paola Leone, PhD, of the University of Medicine and Dentistry of New Jersey-School of Osteopathic Medicine (UMDNJ-SOM), demonstrates the long term safety and benefit of a virus-based gene therapy that has been applied for the first time in a clinical setting.

New low-cost combined therapy shows promise against malaria

Malaria brings misery and death to millions in the developing world each year, and fighting it keeps medical researchers up at night because the mosquito-borne parasite Plasmodium falciparum, which causes the deadliest form of the disease, has developed resistance to every drug thrown at it. Resistance has cut short the useful life of nearly every therapy tried so far, experts say.

Researchers create first ever atlas of immune cells in the human body

By analyzing tissues harvested from organ donors, Columbia University Medical Center (CUMC) researchers have created the first ever "atlas" of immune cells in the human body.

UAB research succeeds in testing a vaccine against leishmaniasis

A research coordinated by the UAB has succeeded in testing a vaccine against leishmaniasis. The vaccine was tested with the best animal model existing, the golden hamster, and can be produced at low costs by using insect larvae.

Researcher looks at role of TIMP3 protein linked with aortic aneurysms in the abdomen

A researcher with the Faculty of Medicine & Dentistry and the Mazankowski Alberta Heart Institute is looking closely at a molecule linked to aortic aneurysms in the abdomen, and her findings could lead to a treatment to reduce swelling of the aortic artery, which would be a life-saving treatment.

Mayo Clinic to receive Biomarkers of Gut Function grant

Mayo Clinic announced today that it will receive funding through the Biomarkers of Gut Function and Health program within the Grand Challenges in Global Health initiative. This initiative was launched by the Bill & Melinda Gates Foundation to overcome persistent bottlenecks preventing the creation of new and better health solutions for the developing world. William Faubion, M.D., a Mayo Clinic gastroenterologist, will continue to pursue a research project titled "Gut Permeability in Environmental Enteropathy."

Study shows how to prod stem cells to become 2 different types of blood vessel tissues

Growing new blood vessels in the lab is a tough challenge, but a Johns Hopkins engineering team has solved a major stumbling block: how to prod stem cells to become two different types of tissue that are needed to build tiny networks of veins and arteries.

New MRI scans accurately measure damage to blood-brain barrier in stroke victims

Johns Hopkins researchers have developed a new way of looking at standard MRI scans that more accurately measures damage to the blood-brain barrier in stroke victims, a process they hope will lead to safer, more individualized treatment of blood clots in the brain and better outcomes.
