MMR, also known as CD206 and MRC1 (mannose receptor C, type 1), is a scavenger receptor that is expressed on tissue macrophages, myeloid dendritic cells, and liver and lymphatic endothelial cells. MMR contains eight carbohydrate recognition domains (CRD) which enable the internalization of a wide variety of soluble and pathogen-associated glycans. Once internalized, ligands are released following acidification of phagosomes or endosomes, and the receptor is recycled to the cell surface.
