Food allergy endotypes revisited.

Area of Science:

• Immunology
• Allergy Research
• Biomedical Science

Background:

• Food allergy prevalence has risen significantly over the past century.
• It is a heterogeneous condition with complex underlying mechanisms.
• Biomedical advances have elucidated genetic, environmental, immune, and metabolic factors in food allergy pathogenesis.

Purpose of the Study:

• To propose a framework for classifying distinct food allergy endotypes.
• To define endotypes based on key pathophysiologic features.
• To discuss additional subtypes with unique mechanistic characteristics.

Main Methods:

• Review of current biomedical research on food allergy.
• Analysis of genetic, environmental, immune, and metabolic pathways.
• Classification of food allergy based on defined criteria.

Main Results:

• Identification of distinct food allergy endotypes with unique features.
• Proposed classification criteria include IgE involvement, allergen molecular features, and prognostic markers.
• Discussion of further subtypes based on mechanistic characteristics.

Conclusions:

• A structured classification of food allergy endotypes is crucial for understanding disease heterogeneity.
• Proposed criteria provide a basis for categorizing food allergies.
• Further research into mechanistic subtypes can refine diagnosis and treatment.
