背景信息

Der p 1. a major allergen derived from the house dust mite *Dermatophagoides pteronyssinus*, is a cysteine protease implicated in allergic diseases such as asthma, rhinitis, and atopic dermatitis. As a member of the papain-like protease family, it plays a dual role: facilitating mite digestion (e.g., breaking down skin cell proteins) and triggering human immune responses by cleaving epithelial tight junctions, enhancing allergen penetration and sensitization. Its enzymatic activity contributes to IgE-mediated hypersensitivity, making it a key target in allergy research.

Recombinant Der p 1 (rDer p 1) is produced via genetic engineering in heterologous systems like *E. coli* or yeast, enabling standardized, high-purity production free from contaminants found in native mite extracts. This consistency is critical for diagnostic and therapeutic applications. In clinical settings, rDer p 1 is used in allergy testing to identify sensitized individuals and in immunotherapies designed to desensitize patients through controlled exposure. Structural studies using recombinant forms have elucidated its catalytic mechanism and IgE-binding epitopes, informing the design of hypoallergenic variants with reduced side effects.

Research leveraging rDer p 1 has advanced understanding of protease-activated receptor signaling, Th2 immune polarization, and biomarker discovery for disease monitoring. Its role in vaccine development, including fusion proteins or adjuvanted formulations, highlights its translational potential. By circumventing challenges of natural allergen variability, rDer p 1 serves as a reliable tool for both mechanistic studies and next-generation allergy solutions.
