Abstract
AbstractTo achieve immune and microbial homeostasis during adulthood, the developing immune system must learn to identify which microbes to tolerate and which to defend against. How such ‘immune education’ unfolds remains a major gap in the literature. We address this gap by synthesizing existing literature to develop a mechanistic mathematical model representing the interplay between gut ecology and adaptive immunity in early life. Our results indicate that the inflammatory tone of the microenvironment is the mediator of information flow from pre- to post-weaning periods. We evaluate the power of postnatal fecal samples for predicting immunological trajectories and explore breastfeeding scenarios when maternal immunological conditions affect breastmilk composition. Our work establishes a quantitative basis for ’immune education’, offering insights into questions of applied relevance.
