Fox Chase Cancer Center scientists identify immune-system mutation

...further progress against various immune disorders, allergies and certain cancers, such as those of the blood and bone marrow, that involve a compromised immune system. "As one example, a decrease in the number of CD4 T cells is the primary mechanism by which HIV causes AIDS," Kappes said. The helper-deficien...

Inflammatory molecules released by pollen trigger allergies

...len from unpolluted areas, possibly explaining why allergies are more prevalent in places with high levels of car exhaust emissions. Traidl-Hoffmann and colleagues showed that extracts from birch pollen and other common allergens block the production of a soluble protein by immune cells that normally inhibits...

Novel Therapy Tested in Mice Could Chase Away Cat Allergies

New processing method reduces peanut allergenicity

...e United States, the most significant rise in food allergies has been attributed to peanuts and other nuts. The allergenicity of peanuts is due to the presence of specific types of proteins including Ara h1 and Ara h2. Yu and her colleagues discovered during a study of various processing methods on the allerge...

Bacteria in Household Dust May Trigger Asthma Symptoms

...in adults, regardless of whether an individual has allergies or not" said Peter S. Thorne, Ph.D., a researcher at the University of Iowa and lead author on the paper. "This suggests that exposure to endotoxin increases asthma risk even in non-allergic individuals." Since the mid 1960s, researchers knew that h...

New factor implicated in allergy and asthma attacks

For a person with allergies or asthma, breathing in pollen can be a very bad thing. Within minutes of inhalation by someone sensitive to their effects, these tiny particles can trigger severe inflammation of the respiratory passages, producing uncontrollable sneezing, coughing,...

...rial, fungal, and viral infections (keratitis) and allergies to various dystrophies including keratoconus. "Corneal damage and disorders account for several million cases of impaired vision and are second to cataracts as the most important cause of blindness in the world," explains study author Dr. Jan J. Eng...

'Nano-keys' bind cell receptors and trigger allergic reactions

...e these insights to develop new drug therapies for allergies and other immune responses, high cholesterol and perhaps viral infections. By understanding a membrane's role in cell function, she explained that these nano-keys could interfere with responses via the membrane interactions, rather than just targeti...

A Jekyll and Hyde of cytokines: IL-25 both promotes and limits inflammatory diseases

...rt the notion that the immune response that causes allergies and asthma is an evolutionary hangover resulting from mankind's historical fight with parasitic worm infections. That is, a type 2 response that was once useful in fighting worm infections has now become a dangerous menace, causing inflammatory resp...

Flick of a protein switches immune response

... Because autoimmune diseases ?such as arthritis, allergies and dozens of other illnesses ?begin when the body's defenses respond at the wrong time or place, the on-off mechanism for the immune system has been the subject of intense study for decades. The USC-Harvard team studied proteins critical to immune...

Tests may help answer questions about GMOs and allergies

... a genetically engineered crop potentially causing allergies was StarLink corn. Created by Aventis in 1996, StarLink contained the cry9C protein from a common soil bacterium, a strain of Bacillus thuringiensis. The cry9C protein protected the corn from several types of corn borers and black cutworms. StarLink ...

Children of allergy sufferers prone to same problem

Infants whose parents have allergies that produce symptoms like wheezing, asthma, hay fever or hives risk developing allergic sensitization much earlier in life than previously reported, according to a study by Cincinnati researchers. The study suggests that the current practice of av...
