Sensory neurons remember past allergens to trigger future allergic reactions

Mass General Brigham researchers found that sensory neurons retain a 'memory' of allergens that may help explain why allergies develop over time.

Can maternal diet prevent infant food allergy? A large trial puts eggs and peanuts to the test

A large Australian randomized trial of 2,137 pregnant women tested whether substantially increasing egg and peanut consumption during pregnancy and breastfeeding could prevent food allergy in infants with a strong family history of allergic disease. Higher maternal intake did not significantly reduce IgE-mediated egg or peanut allergy at 1 year, although the lower-than-expected allergy rate limited statistical power and the results could not exclude a clinically important benefit.

Silica and dust mites combine to worsen asthma inflammation

Inflammation associated with asthma and other allergic airway diseases can be significantly worsened by exposure to both house dust mite allergens and crystalline silica, according to a new study published in the journal Allergy.

Children's Colorado launches new program to expand treatment options for children with food allergies

Children's Hospital Colorado's Allergy and Immunology Center today launched its Sublingual Immunotherapy Program at its Anschutz Medical Campus in Aurora, expanding treatment options for children with certain food allergies.

Fruit fly brain inspires energy-efficient scent classification algorithm

In the animal kingdom, energy conservation is essential for survival. That's why our brains have evolved to be extremely energy and resource efficient at storing and processing information.

Researchers uncover mechanism linking skin inflammation to body-wide allergies

Our bodies experience allergic reactions when the immune system mistakenly overreacts to harmless substances, known as allergens, such as pollen, dust, or certain foods.

Microbiome-based therapy may increase peanut allergy tolerance in adults

Some 33 million Americans have severe food allergies. Now, researchers at Boston Children's Hospital may have found a promising solution.

Omalizumab beats multiallergen oral immunotherapy in multifood allergy trial

Omalizumab demonstrates higher treatment success for multifood allergies compared to oral immunotherapy, with fewer adverse events impacting patient retention.

New diagnostic blood test improves food allergy detection accuracy

Allergies can be minor or life-threatening, and current diagnostic blood tests are not always adequate at determining which substances patients need to avoid to prevent a reaction.

New Mount Sinai center focuses on advancing personalized treatments for peanut allergy

Researchers at the Icahn School of Medicine at Mount Sinai have been awarded a five-year, $7.2 million grant from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), to establish a new Asthma and Allergic Diseases Cooperative Research Center focused on advancing personalized treatment strategies for peanut allergy.

Engineered immune cells suppress asthma symptoms in allergic mice

Genetically engineered CAR T cells expressing artificial receptor proteins are increasingly used in the clinic to boost the immune system's response against leukemias and other cancers.

Nasal viruses may drive allergic rhinitis, and ribavirin shows early promise as a targeted spray treatment

Nasal commensal viruses may worsen allergic rhinitis by activating type I IFN-linked neutrophils and NET formation. Ribavirin reduced nasal viral abundance and improved symptoms in mice and in a small phase 2 trial.

No link between cat ownership and asthma flare-ups in children

A study of over 30,000 children reveals no link between cat exposure and asthma outcomes, challenging previous concerns about pet ownership and asthma control.

Study finds indoor cats do not trigger child asthma flares

Asthma is the most common chronic disease and one of the main causes of hospitalization among children. The Global Asthma Network has estimated that its global prevalence is 9.1% for children and 11.0% for adolescents, but this percentage varies greatly between countries, regions, and environments.

Review explores diagnosis and management of perioperative anaphylaxis during anesthesia

Perioperative anaphylaxis is a rare, life‑threatening condition during anesthesia. The unique setting – multiple drugs, patient draping, and altered physiology – causes higher mortality than anaphylaxis elsewhere.

PET microplastics remain in lungs and worsen respiratory tract inflammation

Microplastics (MP) are the subject of intensive medical research, but little is yet known about their effects on the immune system.

Silica nanoparticles dampen early allergy signals in mouse mast cells

This in vitro study found that negatively charged SiO2 nanoparticles suppressed antigen-induced degranulation and activation-marker changes in IgE-sensitized mouse bone marrow-derived mast cells. By contrast, mTiO2 nanoparticles showed cytotoxic and pro-inflammatory effects, including enhanced DNP-induced IL-6 release, suggesting nanoparticle composition can shape early allergic immune responses.

Experts establish standardized protocols for pediatric recurrent wheezing diagnosis

Recurrent wheezing, a respiratory disorder, is caused by the narrowing of the airways, mainly affecting children aged less than 5 years.

Study finds cockroach allergy often driven by shared proteins across arthropods

Researchers analyzed molecular sensitization patterns in Polish patients with perennial allergic rhinitis who tested positive for cockroach allergens. They found that most apparent cockroach allergies were driven by cross-reactive proteins shared with mites, seafood, and other arthropods rather than true cockroach-specific allergens.
