Researchers discover new culprit in atherosclerosis
January 7, 2012 by admin · Leave a Comment
A new study by NYU Langone Medical Center researchers identified a new culprit that leads to atherosclerosis, the accumulation of fat and cholesterol that hardens into plaque and narrows arteries. The research, published online by Nature Immunology on January 8, 2012, explains why cholesterol-laden, coronary artery disease-causing cells called macrophages, accumulate in artery plaques.
UCLA study shows loss of key estrogen regulator may lead to metabolic syndrome and atherosclerosis
September 5, 2011 by admin · Leave a Comment
FINDINGS: UCLA researchers demonstrated that loss of a key protein that regulates estrogen and immune activity in the body could lead to aspects of metabolic syndrome, a combination of conditions that can cause Type 2 diabetes, atherosclerosis and cancer. Called estrogen receptor alpha, this protein is critical in regulating immune system activity such as helping cells suppress inflammation and gobble-up debris.
Gene therapy delivered once to blood vessel wall protects against atherosclerosis in rabbit studies

Future experiments will look at using this gene transfer method in bypass grafts
A one-dose method for delivering gene therapy into an arterial wall effectively protects the artery from developing atherosclerosis despite ongoing high blood cholesterol. The promising results, published July 19 in the journal Molecular Therapy, came from research in rabbits.
New cell therapy a promising atherosclerosis treatment
February 28, 2011 by admin · Leave a Comment
Researchers at Karolinska Institutet have shown in a new study on mice, that cell therapy can be used to reverse the effect of ‘bad’ LDL cholesterol and reduce the inflammation that leads to atherosclerosis. The new cell therapy, which is presented in the prestigious scientific journal Circulation, can open the way for new therapies for stroke and myocardial infarction if the results prove translatable to humans.
A new drug target in atherosclerosis: The anaphylatoxin C5a
January 3, 2011 by admin · Leave a Comment
For decades, doctors have looked at fitness levels, weight, and overall health risk factors for heart disease and stroke. Now, they may soon add a new risk factor to the list: activation of the complement system. The complement system is usually implicated in immune responses, but now there’s a role for it in cardiovascular disease. In a new research report appearing in the January 2011 print issue of the FASEB Journal (http://www.fasebj.org), scientists from Europe and the United States show that anaphylatoxin C5a, a protein released when complement is activated, contributes to atherosclerotic disease. C5a causes plaques to break free from where they would be anchored to ultimately cause blockages elsewhere in the body. This new discovery not only shows that C5a is a new marker for identifying risk for heart attack and stroke, but it also establishes C5a as a new therapeutic target for preventing these problems.
Inhibiting fatty acids in immune cells decreases atherosclerosis risk

Scientists at Washington University School of Medicine in St. Louis have found a way to significantly reduce atherosclerosis in mice that does not involve lowering cholesterol levels or eliminating other obesity-related problems.
Antibody-producing B cells promote atherosclerosis in mice

Antibody-producing B cells promote atherosclerosis in mice, according to a study to be published online on July 5th in the Journal of Experimental Medicine (www.jem.org) These findings came as a surprise, as prior studies had suggested that B cells help protect against the disease.
Study shows cocoa flavanols improve vascular and blood pressure measures for coronary artery disease patients

A new study by UCSF cardiologists and researchers found that high concentrations of cocoa flavanols decrease blood pressure, improve the health of blood vessels and increase the number of circulating blood-vessel-forming cells in patients with heart disease. The findings indicate that foods rich in flavanols such as cocoa products, tea, wine, and various fruits and vegetables have a cardio-protective benefit for heart disease patients.
Antioxidant supplementation does help arteries stay healthy

Long-term supplementation with dietary antioxidants has beneficial effects on sugar and fat metabolism, blood pressure and arterial flexibility in patients with multiple cardiovascular risk factors. Researchers writing in BioMed Central’s open access journal Nutrition and Metabolism report these positive results in a randomized controlled trial of combined vitamin C, vitamin E, coenzyme Q10 and selenium capsules.
To predict atherosclerosis, follow the disturbed blood flow

A new animal model of atherosclerosis has allowed researchers to identify a host of genes turned on or off during the initial stages of the process, before a plaque appears in the affected blood vessel.
