Herbalscience research throws light on causes of allergic rhinitis

Most people might think of nettle as simply a common and aggressive weed that can sting and cause skin irritation. But nettle has also been used for hundreds of years to treat seasonal allergies and other inflammatory diseases, although the precise nature of its anti-inflammatory effect was unknown. Now, scientists with HerbalScience have identified specific bioactives in nettle leaf extracts that inhibit in vitro receptors and enzymes known to be key in generating symptoms of allergic rhinitis, or hay fever.

Gleevec holds potential as first drug to successfully treat neurofibromatosis

Researchers at the Indiana University School of Medicine report that the anti-cancer drug Gleevec holds out promise to become the first effective treatment for neurofibromatosis, a genetic disease that has resisted treatments until now.

Discovery of mechanism and possible drug treatment for growth of nerve tumors in neurofibromatosis

Researchers studying neurofibromatosis type 1 - a rare disease in which tumors grow within nerves - have found that the tumors are triggered by crosstalk between cells in the nerves and cells in the blood.

In mice, anxiety is linked to immune system

In the first study ever to genetically link the immune system to normal behavior, scientists at Rockefeller and Columbia universities show that mast cells, known as the pharmacologic bombshells of the immune system, directly influence how mice respond to stressful situations.

Luna awarded NIH grant for fullerene-based nanomedicines as allergy treatments

Luna Innovations Incorporated has announced the award of a $1.6 million Research Project Grant (R01) from the National Institutes of Health (NIH) to investigate the use of fullerene-based nanomedicines as a pathway to treat allergies and other inflammatory diseases.

Asthma medicines often not prescribed as guidelines recommend

More than a decade after national guidelines were issued for asthma treatment, some patients still don't receive prescriptions for the inhalers that experts say offer the safest and most effective long-term control of the disease, a new study suggests.

How asthma and allergy symptoms are triggered

In demonstrating that a group of calcium ion channels play a crucial role in triggering inflammatory responses, researchers at Beth Israel Deaconess Medical Center (BIDMC) have not only solved a longstanding molecular mystery regarding the onset of asthma and allergy symptoms, but have also provided a fundamental discovery regarding the functioning of mast cells.

Protein a possible key to allergy and asthma control

Activating a protein found on some immune cells seems to halt the cells' typical job of spewing out substances that launch allergic reactions, a study by Johns Hopkins researchers suggests.

Protein in mice known as RGS13 suppresses allergic reactions

A protein in mice known as RGS13 suppresses allergic reactions, including the severe, life-threatening allergic reaction known as anaphylaxis, according to scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).

Abnormal immune cells may cause unprovoked idiopathic anaphylaxis

Two new clinical reports shed light on why some people suffer from recurrent episodes of idiopathic anaphylaxis--a potentially life-threatening condition of unknown cause characterized by a drop in blood pressure, fainting episodes, difficulty in breathing, and wheezing.

Cell that triggers symptoms in allergy attacks can also limit damage

A blood cell known as a troublemaker for triggering the itch and inflammation in allergy attacks, the mast cell, can also calm down the flare-ups, researchers from Stanford University School of Medicine have found.

New approach for tackling allergies

Allergies, like the common cold and asthma, have basically defied the best efforts of modern medicine to cure them.

"Allergy cells" can aggravate cancer and psoriasis

The body's mast cells are mainly associated with allergic reaction in the way they release histamine and other inflammatory substances.

Enzyme released by cardiac mast cells during heart attack contributes to arrhythmia

In times of cardiac crisis, mast cells in the heart secrete a powerful enzyme, renin, that indirectly triggers dangerous arrhythmias, according to a team of researchers at the Weill Medical College of Cornell University in New York City.

Is winter flu worse because of exercise-induced 'window of susceptibility'?

When you exercise or work outside in winter, that dry feeling at the back of your throat indicates the cold air has irritated your throat. Racehorses share a similar experience: exercising in below-freezing air causes mild airway injury.

Cells linked to asthma and eczema also help cure deadly illness in mice

Mast cells are immune cells known mostly for their unwanted effects: they cause the wheezing of asthma, the itching of eczema, the sneezing and runny nose of hay fever and, in extreme cases, the life-threatening shock of anaphylaxis.

Researchers identify a protein that could banish allergies

The suffering of millions of people with allergies could one day be eased thanks to new research from UK investigators. Findings from the University College London branch of the Ludwig Institute for Cancer Research (LICR), published in the Oct 2004 issue of Nature, detail how inactivating a key signalling molecule called p110delta reduced the effect of allergies on mice.

Australian researchers hunt for eczema genes

The Queensland Institute of Medical Research (QIMR) is halfway through a major project examining possible genetic causes of atopic dermatitis which is the most common form of eczema.
