Why are urban children more prone to allergies? May 14, 2025
Evidence of a unique T cell may explain why urban children are more prone to allergies than rural children. Differences in the development of the gut microbiome may be an underlying cause.
New bioactive compound for difficult-to-treat allergies April 24, 2025
Irritable bowel syndrome, chronic itching, asthma and migraine are in many cases hard-to-treat conditions. They have in common that they are triggered by an excessive immune response -- which in severe cases can be life-threatening. A team of researchers has now identified a promising bioactive compound that could effectively reduce symptoms and slash fatality risk. […]
Recently discovered immune cell type is key to understanding food allergies April 14, 2025
A new study has revealed that a special group of cells in the intestines tamp down the immune responses caused by exposure to food proteins. Called 'tolerogenic dendritic cells,' these cells enable food to pass through the body without triggering an immune reaction, unless they malfunction to cause allergies.
Researchers find intestinal immune cell prevents food allergies April 3, 2025
Researchers found that a small population of immune cells in the mouse intestine prevents allergic responses to food, suggesting that targeting such cells therapeutically could potentially lead to a new treatment for allergies.
Surgery doesn't always help with chronic rhinosinusitis -- a new risk score predicts treatment efficacy April 3, 2025
A new CT-scan based risk score facilitates the identification of patients at risk of revision endoscopic sinus surgery due to chronic rhinosinusitis.
Eating gradually increasing doses of peanut butter enables children with high-threshold allergy to safely consume peanuts, study suggests February 10, 2025
Findings suggest a safe, inexpensive, and effective pathway for allergists to treat children who already tolerate at least half a peanut.
Molecular basis of food allergy February 3, 2025
A multi-institutional study has identified one of the allergens responsible for eosinophilic esophagitis (EoE), an inflammatory disease of the esophagus. This is the first time one of the allergens that causes EoE has been identified at a molecular level.
Why you shouldn't scratch an itchy rash: New study explains January 30, 2025
Your parents were right: Scratching an itchy rash really does make it worse. Now we know why, thanks to new research that uncovers how scratching aggravates inflammation and swelling in a mouse model of a type of eczema called allergic contact dermatitis.
New clues to the mechanism behind food tolerance and allergies January 28, 2025
Study reveals how immune cells in the gut distinguish between food and harmful pathogens, shedding light on the origins of both food allergies and intestinal diseases.
Discovery of genetic loci associated with allergic sensitization January 21, 2025
A research team performed a large-scale genome analysis of Japanese and European populations and discovered gene regions (genetic polymorphisms) related to allergic sensitization. Some of these sensitization-related genetic polymorphisms were shared by both populations, and others were Japanese-specific. Importantly, genetic polymorphisms linked to polysensitization were identified for the first time. These findings are anticipated to […]
