Executive Industry Relevance

Quantitative assessment of bacterial transcytosis by M cells in Peyer’s patches addresses a critical gap in understanding mucosal immune surveillance and host-microbe interactions. This assay enables mechanistic de-risking of antigen uptake pathways, supporting predictive confidence in early immunology and microbiome-targeted discovery. The method’s ability to distinguish bacterial species transcytosed by M cells informs target validation and portfolio triage for mucosal immunomodulation strategies.
