ABSTRACT
A recent report by Fan et al. identifies trans-vaccenic acid, a maternal diet-derived lipid transferred through breast milk, as a key regulator of neonatal T-cell development. Beyond identifying a single bioactive metabolite, this study positions breast milk as a source of developmental signals that shape lifelong immune competence.
