For a gut immunity system such as Peyer's patch to work, it is necessary to supply antigens into the gut lumen through the intestinal epithelia.

Special epithelial cells called M cells exist in the intestinal epithelia and they are thought to assume a role of transporting antigens from the intestinal epithelia to the intestinal immune system; however, details of differentiation and the functions of M cells have not been clarified.

As a result of examining specific genes in M cells, we found that a molecule called glycoprotein 2 (GP2) appears specifically in M cells and works as a receptor uptaking E. coli or salmonella and this is essential for an efficient immunological response.
