- Blocking immune cell action increases Alzheimer's-associated protein deposits
03-27-2007 · EurekAlert!
The immune system's response against amyloid-beta, the protein that forms plaques in the brains of patients with Alzheimer's disease, appears to protect the brain from damage in early stages of the devastating neurological disorder. A report from Massachusetts General Hospital researchers finds that lack of a protein required for recruitment of the brain's primary immune cell led to increased amyloid-beta deposits and earlier death in a mouse model of Alzheimer's disease.

- Deactivating protein may protect nerve fibers in MS
04-23-2007 · EurekAlert!
Oregon Health & Science University neuroscientists are eyeing a protein as a potential therapeutic target for multiple sclerosis because de-activating it protects nerve fibers from damage. OHSU researchers have shown that genetically inactivating a protein called cyclophilin D can protect nerve fibers in a mouse model of multiple sclerosis. Cyclophin D is a key regulator of molecular processes in the nerve cell's powerhouse, the mitochondrion, and can participate in nerve fiber death.

02-08-2007 · EurekAlert!
Researchers at the University of Pennsylvania School of Medicine are the first to show that a mouse protein, whose human equivalent is related to defense against HIV-1, inhibits the infection and spread of a mouse tumor virus. The study provides a new model for the discovery and evaluation of anti-HIV drugs.

- Carbon monoxide protects mice from multiple sclerosis
01-25-2007 · EurekAlert!
Multiple sclerosis (MS) is a chronic inflammatory disorder that causes degeneration of the nerves in the brain and spinal cord, leading to various symptoms including muscle weakness and pain. Using a mouse model of MS (known as EAE), researchers have now shown that increased expression of a protein known as HO-1, as well as administration of carbon monoxide, protects mice from disease.

- Rosemary chicken protects your brain from free radicals
10-30-2007 · EurekAlert!
A collaborative group from the Burnham Institute for Medical Research (Burnham Institute) in La Jolla, Calif., and in Japan, report that the herb rosemary contains an ingredient that fights off free radical damage in the brain. The active ingredient in rosemary, known as carnosic acid, can protect the brain from stroke and neurodegeneration that is due to injurious chemical free radicals.

- Animal study identifies potential treatment for Huntington's disease
10-08-2007 · EurekAlert!
Mass. General Institute for Neurodegererative Disorders researchers have identified a compound that may lead to a treatment that could protect against the effects of Huntington's Disease. Their report describes how a small molecule called C2-8 appears to delay the loss of motor control and reduce neurological damage in a mouse model of the disorder.

- Early environmental exposure may accelerate age-related neurodegeneration
06-27-2007 · EurekAlert!
Exposure to iron during the first weeks of life in combination with exposure later in life to a common herbicide may contribute to the subsequent degeneration of brain cells associated with the onset of Parkinson's disease (PD), according to a new study in mice. The findings also showed that a compound that protects cells in the body from damage from certain forms of oxygen, a kind of antioxidant, could suppress such neural degeneration.
