Insights

BufeiJianpi Mixture (BFJPM) effectively manages food allergies in mice by reducing symptoms and IgE levels. It also positively reshapes the gut microbiota, highlighting its therapeutic potential.

Area of Science:

  • Integrative Medicine
  • Immunology
  • Microbiome Research

Background:

  • Allergic constitution in children presents a clinical challenge.
  • BufeiJianpi Mixture (BFJPM) is a traditional herbal formula used for managing allergic conditions.
  • Understanding BFJPM's impact on food allergy and gut microbiota is crucial.

Purpose of the Study:

  • To evaluate the therapeutic efficacy of BFJPM in an OVA-induced murine model of food allergy.
  • To investigate BFJPM's effects on the gut microbiota composition and function.
  • To identify key molecular targets and pathways involved in BFJPM's action using network pharmacology.

Main Methods:

  • Established a food allergy model in BALB/c mice using Ovalbumin (OVA).
  • Assessed therapeutic efficacy via symptom scores, V/C ratio, and serum IgE levels.
  • Analyzed gut microbiota using 16S rRNA sequencing and predicted functions with PICRUSt2; employed network pharmacology for target identification.

Main Results:

  • BFJPM significantly reduced allergy symptoms, serum IgE, and improved intestinal V/C ratio.
  • BFJPM altered gut microbiota structure, increasing richness and enriching *Actinobacteria* and *Candidatus Arthromitus*.
  • Network pharmacology identified IL6, TNF, and IL10 as key targets, with the African trypanosomiasis pathway implicated.

Conclusions:

  • BFJPM alleviates OVA-induced food allergy symptoms and modulates the gut microbiota in mice.
  • *Saccharopolyspora* enrichment and the African trypanosomiasis pathway are potential mechanisms.
  • Further research is needed to establish the causal link between microbiota changes and therapeutic effects.
