Abstract:
:Vitamin A and its metabolite retinoic acid influence various aspects of immunity. Although the capacity of vitamin A to condition intestinal CD103(+) DCs to imprint tissue-specific homing programs onto activated lymphocytes is well documented, it is unclear whether vitamin A also regulates DC populations in other tissues. A study published in this issue of the European Journal of Immunology, Beijer et al. [Eur. J. Immunol. 2013. 43: 1608-1616] now demonstrates that vitamin A exerts profound effects on the subset composition of splenic DCs. By resolving that splenic ESAM(hi) CD11b(hi) DCs are preferentially responsive to regulation by vitamin A, these novel insights not only further support the notion that ESAM expression marks two distinct lineages of splenic CD11b(hi) DCs, but also provide an important extension to our understanding of how vitamin A influences the immune system.
