Research Abstract |
Peyer's patch (PP) in the small intestine is a primary site for the intestinal immune system. The luminal side of PPs is covered by the follicle-associated epithelium (FAE), which contains M cells, which uptake antigens or macromolecules, and deliver them to dendritic cells inhabiting subepithelial dome region under FAE. CCR1 is a receptor of Ccl9 which is belonging to the CC chemokine family and highly expressed in M cells. We found that CCR1 positive cells inhabit subepithelial dome region, and some of them contact with M cells. Moreover, our study suggests that CCR1 positive cell belongs to a subtype of antigen-producing plasma cells.
