Research in animals and people supports a range of mechanisms by which the parasites affect physiology and immune responses.

More-accurate predictions of the severity of an upcoming grass pollen season based on rainfall and temperature could help allergy sufferers manage their symptoms.

The majority of people experiencing anaphylaxis had a history of allergic reactions, a report by the agency finds.

The decision, which concerns the removal of a sugar molecule on the surface of cells in a line of domestic pigs, marks the first time an approval has been granted for both purposes simultaneously.

In mice, a group of nasal epithelial cells called brush cells release pro-inflammatory signals in response to allergens.

Recent work in humans and mice highlights how exposure to environmental microbes helps protect against allergies and other inflammatory diseases.

A study in patients identifies a nontraditional immune pathway that can cause a severe reaction to anesthetic drugs.

As evidence grows that gut bacteria play roles in the development and persistence of food allergies, researchers begin to explore microbe-based interventions.

With her husband, she studied allergic reactions and identified antibodies that set off itching, wheezing, and rashes.

Although the oral treatment seems to work, an analysis of the results from 12 clinical trials finds kids who got an immunotherapy have a greater rate of serious reactions.

High salt concentrations are present in the affected skin of people with atopic dermatitis and promote the differentiation of the T helper cells involved in the development of allergic diseases.

A study finds the effect is dose-dependent, with each additional pet further lowering the odds of developing allergies.

Scientists are beginning to unravel the ways in which we develop a healthy relationship with the bugs in our bodies.

Four years after taking a probiotic and peanut protein for 18 months, two-thirds of children in a small clinical trial can eat peanuts with no health issues.

In the 1960s, immunologists took matters into their own hands—and under their own skin—to characterize an immunoglobulin involved in allergies.

In light of recent allergen-exposure studies, an agency-sponsored panel has formally recommended early introduction of peanuts in an effort to prevent potentially life-threatening allergies.

Egg and peanut consumption during infancy is linked to lower risk of allergy to those foods later in life, according to a meta-analysis.

What researchers are learning as they sequence, map, and decode species’ genomes

The findings of a longitudinal study in New Zealand lend support to the hygiene hypothesis.
