Molecular biomarkers for grass pollen immunotherapy

Area of Science:

• Allergy and Immunology
• Biomarker Discovery
• Immunotherapy

Background:

• Grass pollen allergy is a major global health concern.
• Component-resolved diagnosis (CRD) improves grass pollen allergen sensitization assessment.
• Allergy immunotherapy (AIT) is crucial for managing grass pollen allergies, especially where pollen seasons overlap.

Purpose of the Study:

• To explore candidate predictive biomarkers for grass pollen immunotherapy (AIT).
• To identify biomarkers for early detection of AIT responders.
• To support AIT patient follow-up and new allergy vaccine development.

Main Methods:

• Investigated biomarkers including tolerogenic dendritic cells, regulatory T cells, and serum blocking antibodies.
• Examined functional antibodies, immune activation, immune tolerance soluble biomarkers, and apoptosis biomarkers.
• Utilized component-resolved diagnosis for allergen sensitization evaluation.

Main Results:

• Identified potential biomarkers for predicting AIT clinical response.
• Established a basis for early identification of patients likely to benefit from AIT.
• Highlighted opportunities for improved AIT follow-up and novel vaccine strategies.

Conclusions:

• Candidate biomarkers show promise for optimizing grass pollen AIT.
• Biomarker discovery can enhance personalized allergy treatment and vaccine development.
• Further research into these biomarkers will advance allergy management strategies.
