## TL;DR

Scientists engineered safer allergy vaccines using modified proteins that reduce allergic reactions and inflammation in mice.

## Contribution

The study introduces chimeric hypoallergens QBD2/QBD4 that effectively suppress allergic responses better than existing options.

## Key findings

- QBD4 reduces IgE reactivity and airway inflammation in mice.
- QBD4 promotes Th1/regulatory immune responses more effectively than QBD2.
- QBD4 suppresses mucus production and eosinophilia better than QBD2.

## Abstract

Chimeric hypoallergens of Der p 1 and Blo t 1 (QBD2/QBD4) reduce IgE reactivity and airway inflammation in mice.QBD4 promotes Th1/regulatory responses, suppressing mucus and eosinophilia more effectively than QBD2.

Chimeric hypoallergens of Der p 1 and Blo t 1 (QBD2/QBD4) reduce IgE reactivity and airway inflammation in mice.

QBD4 promotes Th1/regulatory responses, suppressing mucus and eosinophilia more effectively than QBD2.
