Abstract excerpt
BACKGROUND & AIMS: Reduced generation of all-trans retinoic acid (RA) by CD103(+) intestinal dendritic cells (DCs) is linked to intestinal inflammation in mice. However, the role of RA in intestinal inflammation in humans is unclear. We investigated which antigen-presenting cells (APCs) produce RA in the human intestine and whether generation of RA is reduced in patients with Crohn's disease (CD). METHODS: Ileal...
