Dermatophagoides pteronyssinus allergen Der p 1 (Der p 1)

Target
Der p 1
Molecular classification
Enzyme, Cysteine protease, Allergen
01

Overview

Der p 1 is a major allergen produced by the house dust mite Dermatophagoides pteronyssinus. It is a cysteine protease that disrupts epithelial barriers and induces inflammatory responses, contributing to allergic diseases such as asthma and allergic rhinitis.
