Specialized M cells in the follicle-associated epithelium of intestinal Peyer's patches serve as portals for diverse particulates. Following antigen handover to dome lymphocytes, a protective mucosal antibody secretion ensues. One approach to oral vaccine delivery is to mimic the entry pathways of pathogens via M cells. The paucity of human tissue for in vitro investigation has hampered the discovery of M-cell pathogen receptors; however an in vitro human M like-cell culture model displays many expected phenotypic features.

Peyer's patches are covered by a special follicle-associated epithelium that contains specialized cells called microfold cells (M cells) which sample antigen directly from the lumen and deliver it to antigen-presenting cells (located in a unique pocket-like structure on their basolateral side). Dendritic cells and macrophages. Receive free email-alerts when new articles cite this article. In the intestine, the follicle-associated epithelium (FAE) of Peyer's patches (PP) performs Ag sampling as the first step in devel. Differentiation and uptake processes of M cells are not known, in part because their limited number in the intestinal mucosa has.

Comparative studies using microarrays reveal several novel M-cell surface receptors that could be used to potentially target orally delivered antigens. • Previous article in issue • Next article in issue.
