New Biomarkers in Anaphylaxis (Beyond Tryptase)

Area of Science:

• Immunology
• Allergy
• Pathophysiology

Background:

• Anaphylaxis is a severe allergic reaction with complex underlying mechanisms.
• Current understanding often focuses on IgE-dependent pathways, but other mechanisms are increasingly recognized.

Purpose of the Study:

• To elucidate the pathophysiology of anaphylaxis, including mechanisms, effector cells, and biomarkers.
• To explore potential biomarkers beyond tryptase and investigate non-IgE-dependent pathways.

Main Methods:

• This is a review article, synthesizing existing research on anaphylaxis.
• Literature search focused on anaphylaxis pathophysiology, cellular mechanisms, and biomarkers.

Main Results:

• Identified various mediators and cellular pathways involved in different anaphylaxis endotypes.
• Highlighted the potential roles of platelet activation factor, basogranulin, dipeptidyl peptidase I, CCL-2, and other cytokines.
• Explored non-IgE-dependent pathways contributing to anaphylaxis.

Conclusions:

• Understanding diverse anaphylaxis endotypes and their mediators is crucial for precision medicine.
• Biomarker discovery and pathway elucidation can improve severity stratification and risk prediction in anaphylaxis.
