Transepithelial transport and mucosal defence I: the role of M cells
Trends in Cell Biology
Journal Article --- Old month value: May
How do cells of the immune system encounter the majority of antigens that enter the body through the gut and airways? The epithelia lining these systems contain a remarkable cell type, the M cell, that delivers antigens across the epithelium to lymphocytes and macrophages. In this article, Marian Neutra and Jean-Pierre Kraehenbuhl describe the structure of the M cell, its function in promoting the immune response and its exploitation by invading pathogens. In the next issue of Trends in Cell Biology, these authors will review the other immunological function of epithelia, secretion of polymeric IgA.
