Highlight

  • The maturity of the early-life gut microbiome critically regulates blood-brain barrier (BBB) permeability during brain development.
  • Full-term infant-derived microbiota enhances cognitive outcomes and BBB integrity compared to preterm-derived microbiota in murine models.
  • Single-cell RNA sequencing reveals that prematurity-associated microbiota downregulates synaptic signaling genes in BBB cells.
  • Metagenomics and metabolomics identify specific bacterial populations and metabolic pathways linked to neurodevelopmental benefits.
