Key Points

The aim is to characterize the immune responses of CD4+ T cell subsets in pediatric cow milk allergy and examine the role of gut microbiota.
Characterization of allergen-specific immune responses in pediatric cow milk allergy
Investigation of conventional (Tcon) and regulatory (Treg) CD4+ T cell subsets
Analysis of gut microbiome composition and its influence on immune responses
Identified distinct CD4+ T cell responses associated with IgE and non-IgE mediated cow milk allergy
Demonstrated significant differences in gut microbial composition between CMA endotypes
Found correlations between gut microbiota and immune response profiles in children with cow milk allergy

Abstract

Pediatric cow milk allergy (CMA) is a highly prevalent food allergy which manifests as IgE or Non-IgE mediated type. However, the underlying CD4+ T cell immune responses associated, particularly with non-IgE mediated CMA remain poorly characterized. As gut microbiome plays a pivotal role in the modulation of CD4+ T cell immune responses in allergy, this study aimed to characterize allergen-specific immune responses mediated by conventional (Tcon) and regulatory (Treg) CD4+ T cell subsets and to investigate the influence of the gut microbiota on these immune responses in pediatric CMA.
