Balanced intestinal retinoic acid concentrations are essential to maintain immune homeostasis in the gut. In this issue of Cell Host & Microbe, Bonakdar et al, sheds light on metabolic host-microbiota interactions and elegantly links diet, microbiota and host functions at the molecular level in the context of vitamin A metabolism.
