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. M-cells uptake antigens or macromolecules and deliver them to dendritic cells inhabiting subepithelial dome region under FAE. We found high expression level of a chemokine gene, Ccl9, in the M cells by using the mouse chemokine array and in situ hybridization analysis. The cells expressing CCR1 protein, a receptor of CCL9, were found underneath M cells and close contact with. Moreover, M cells expressed a gene of M-Sec which product is a key molecule of the formation of membrane nanotubes, a new structure for cell-cell communication. Taken together, our data suggest that M cells interact and communicate with immune cells by two ways, CCL9-CCR1 and membrane nanotubes.
