The process of antigen transcytosis carried out by M cells in the mucosal-associated lymphoid tissue (MALT). Transcytosis is the process of the directed movement of endocytosed material through the cell and its exocytosis from the plasma membrane at the opposite side. M cells are specialized epithelia cells with a microfold structure that are adept at moving antigens from the gut lumen to antigen presenting cells in the MALT. The directed movement of endocytosed material through the cell and its exocytosis from the plasma membrane at the opposite side. The process of transporting immunoglobulin, via transcytosis, from one side of an epithelial cell to the other. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. The directed movement of substances (such as macromolecules, small molecules, ions) into, out of, within or between cells, or within a multicellular organism by means of some external agent such as a transporter or pore. The directed movement of substances into, out of or within a cell by a cellular process that begins with the formation of membrane-bounded vesicles in which the transported substances are enclosed or located in the vesicle membrane. Vesicles are then targeted to, and fuse with, an acceptor membrane.
