Clone NKM 16-2-4 specifically binds (1,2)-fucose–containing carbohydrate moieties on murine microfold cells (M cells or membranous cells). Villous M cells are located in follicle-associated epithelium of Peyer’ s patches (PPs) and nasopharynx-associated lymphoid tissue (NALT). NKM 16-2-4 specifically binds to all subsets of M cells, but not epithelial cells or goblet cells located in PPs, NALT, and the intestinal villi in the gastrointestinal or respiratory tracts.
Microfold cells or membranous cells (M cells) have a high transcytotic activity and play an important role in the uptake of luminal antigens for induction of antigen-specific immune responses. This antibody (clone NKM 16-2-4) specifically binds to all subsets of M cells, but not epithelial cells or goblet cells located in Peyer's patches, nasopharynx-associated lymphoid tissue, and the intestinal villi in the gastrointestinal or respiratory tracts.
