Downstate researchers target multiple sclerosis
November 22, 2006Researchers at SUNY Downstate Medical Center have developed a substance that inhibits the progress of multiple sclerosis (MS) in an animal model. The agent, a novel calpain inhibitor, can be administered orally.
Calpains are a family of proteolytic enzymes naturally found in the human body. Inappropriate activation of calpain is associated with a number of neurodegenerative and autoimmune diseases such as MS. It is known to destroy the myelin sheath that coats and protects the nerves.
In a paper published in the Journal of Neuroimmunology, SUNY Downstate and Maimonides Medical Center researchers described the use of the calpain inhibitor for the treatment of a mouse model of MS. Whether administered by injection or by mouth, the inhibitor produced an almost complete cessation of the disease's progress.
The calpain inhibitor, developed at Downstate, was shown to reduce clinical illness signs and prevent demyelination and inflammatory infiltration in a dose- and time-dependant manner, and holds promise in treating both the acute and chronic phases of MS. The inhibitor may also prove beneficial for treating other degenerative illnesses, such as Alzheimer's, Huntington's and Parkinson's disease.

Multiple Sclerosis News and Current Multiple Sclerosis Events RSSTrapping 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 the Emory Vaccine Center have found.

Protein complementarity may offer new insights into autoimmune diseases
The discovery of "complementary" antibodies against plasminogen in patients with blood vessel inflammation caused by anti-neutrophil cytoplasmic autoantibodies (ANCAs) may lead to new approaches to research, testing, and treatment of ANCA vasculitis and other autoimmune diseases, suggests a paper in the December Journal of the American Society of Nephrology (JASN).
UNC study: shape, not just size, impacts effectiveness of emerging nanomedicine therapies
In the budding field of nanotechnology, scientists already know that size does matter. But now, researchers at the University of North Carolina at Chapel Hill have shown that shape matters even more - a finding that could lead to new and more effective methods for treating cancer and other diseases, from diabetes and multiple sclerosis to arthritis and obesity.
Multiple Sclerosis: new MRI contrast medium enables early diagnosis in animal model
In an animal model of multiple sclerosis (MS), neuroradiologists and neurologists of the University hospitals of Heidelberg and Würzburg have been able to visualize inflammatory tissue damage, most of which had remained unrecognized up to now, with the aid of a new contrast medium, Gadofluorine M, in magnetic resonance imaging.
New Guidelines for Treating Rheumatoid Arthritis
Proven combinations of medicines and the introduction of new anti-arthritis drugs have significantly improved the treatment of rheumatoid arthritis (RA), according to guidelines issued by the American College of Rheumatology and co-authored by physicians at the University of Alabama at Birmingham (UAB).
Milestone for cannabinoid MS study
The CUPID (Cannabinoid Use in Progressive Inflammatory brain Disease) study at the Peninsula Medical School in Plymouth has reached an important milestone with the news that the full cohort of 493 people with multiple sclerosis (MS) has been recruited to the study.
Statins have unexpected effect on pool of powerful brain cells
Cholesterol-lowering drugs known as statins have a profound effect on an elite group of cells important to brain health as we age, scientists at the University of Rochester Medical Center have found. The new findings shed light on a long-debated potential role for statins in the area of dementia.
Best treatment for MS may depend on disease subtype
Animal studies by University of Michigan scientists suggest that people who experience the same clinical signs of multiple sclerosis (MS) may have different forms of the disease that require different kinds of treatment.
Medicines derived from cannabis: a review of adverse events
Researchers at the McGill University Health Centre (MUHC), McGill University and the University of British Columbia (UBC) determined that medical use of cannabinoids do not cause an increase in serious adverse events, but are associated with an increase in some non-serious adverse events.
