Abstract:
Breastfeeding provides infection protection for several pathogens but not for noroviruses. Mechanisms explaining this discrepancy have been unclear. In this issue of Cell Host & Microbe, Peiper et al. demonstrate that while breastmilk protects mice from intestinal damage, it promotes neonatal murine norovirus infection due to maternal-derived bile acids.1.
