'Nondanger' signal lowers immune reactions

05-15-2007 · EurekAlert!

Rheumatology researchers have discovered that a well-known cell receptor sends a signal to dampen the immune system. While not having an immediate application to treating disease, the finding raises the possibility that by targeting that receptor, physicians could stimulate a "nondanger" signal to rein in overzealous human immune responses. Controlling those responses could potentially protect transplant patients from rejection episodes or could relieve symptoms of autoimmune diseases such as rheumatoid arthritis and lupus.

Weak immune response critical to disease that causes most infant hospitalizations
04-05-2007 · EurekAlert!
For the past four decades, medical science thought it knew how severe RSV infections arose. Scientists blamed an overreaction in the lungs by specific immune-system cells, T lymphocytes (also known as "T cells"), for the most drastic symptoms of infection. But now, researchers have shown that severe RSV infections in the lower respiratory tract actually are associated with an inadequate immune reaction -- a characteristic they share with fatal influenza infections.

Protein suppresses allergic response in mice
11-18-2007 · EurekAlert!
A protein in mice known as RGS13 suppresses allergic reactions, including the severe, life-threatening allergic reaction known as anaphylaxis, according to scientists at NIAID. Because RGS13 is also a protein found in humans and is expressed in only a limited number of cells -- including the immune system's mast cells that are central to allergic reactions -- scientists believe the protein may be a target for developing drugs to treat and prevent certain allergic reactions, including anaphylaxis.

Effective HIV control may depend on viral protein targeted by immune cells
12-17-2006 · EurekAlert!
An effective response of the immune system's "killer" T cells against infection with HIV may depend on exactly which viral protein is targeted, according to an international group of researchers. A new study finds that HIV-infected individuals in whom virus-specific CD8 T cells are targeted against the Gag protein have lower viral levels than do those with CD8 responses directed against other viral proteins.

Pioglitazone lowers cardiovascular risk in diabetic patients with kidney disease
12-12-2007 · EurekAlert!
A new study confirms that chronic kidney disease increases the already-high risk of serious cardiovascular events in diabetic patients with damage to the large blood vessels and suggests that treatment with the antidiabetic drug pioglitazone may help to lower this risk, reports the January Journal of the American Society of Nephrology.

Fight against hay fever and other allergies helped by new immune system discovery
12-26-2007 · EurekAlert!
A mechanism which can lead to hay fever and other allergic reactions, by preventing the immune system from regulating itself properly, has been discovered by scientists. Researchers hope their finding, published today in PLoS Biology, will allow therapies to be developed that treat allergies by stopping this mechanism.

Lower transmission increases dengue deaths
02-04-2008 · EurekAlert!
A pair of researchers has answered a puzzle about why efforts to lower the transmission of dengue virus in Thailand have actually increased the severe, life-threatening, form of the infection. Lower transmission rates lead to increased risk of severe infection because of an immune system response.

Transdermal vaccine effective in treating Alzheimer's disease in mouse model
01-22-2007 · EurekAlert!
A novel needle-free vaccine approach was found safe and effective in clearing brain-damaging plaques from mice bred to develop Alzheimer's disease. The transdermal vaccination may offer a simple, noninvasive way of preventing or treating Alzheimer'swith less potential for adverse immune reactions.

Workplace depression screening and enhanced treatment improves productivity, lowers employer costs
09-25-2007 · EurekAlert!
Enhanced and systematic efforts to identify and treat depression in the workplace significantly improves employee health and productivity, likely leading to lower costs overall for the employer, according to a study published Sept. 26, 2007, in the Journal of the American Medical Association. The study was funded by the National Institutes of Health's National Institute of Mental Health.
