Esophageal ulceration activates keratinocyte growth factor and its receptor in rats: implications for ulcer healing.

abstract：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...
