The mannose receptor recognizes the patterns of carbohydrates that decorate the surfaces and cell walls of infectious agents. This macrophage and dendritic cell pattern-recognition receptor mediates endocytosis and phagocytosis. The mannose receptor is the prototype of a new family of multilectin receptor proteins (membrane-spanning receptors containing eight-ten lectin-like domains, which appear to play a key role in host defense) and provides a link between innate and adaptive immunity. Recent advances include the identification of three new members of the mannose receptor family, additional work on defining the molecular requirements for sugar binding, a role for the mannose receptor in antigen presentation of lipoglycan antigens and evidence that the mannose receptor is associated with a signal transduction pathway leading to cytokine production.
