It may contain information that applies to only to some subtypes and species, and so should not be considered definitional. Mononuclear phagocytes are immune cells that form a critical part of the body's innate immune system, the body's first line of defense against infections. Mononuclear phagocytes are characterized by the presence of a single, large nucleus. The ‘Mononuclear Phagocyte System’ nomenclature was introduced to distinguish mononuclear monocytes and macrophages from other cells with multiple nuclei. However, the cells within the mononuclear phagocyte system represent a highly heterogeneous group, all of which are able to perform highly efficient phagocytosis - engulfing and digesting microbes and cellular debris to fight infections and to maintain normal tissue homeostasis. In addition to phagocytosis, mononuclear phagocytes also secrete chemical compounds to recruit other immune cells to a site of infection. These cells produce different types of signaling molecules, including cytokines, chemokines, and reactive oxygen species, triggering a cascade of responses to ensure rapid and efficient containment and neutralization of invading pathogens. These cells are also involved in antigen presentation, a process essential for stimulating an adaptive immune response. They can process and present antigens to T cells, thereby linking the innate and adaptive immune responses. Mononuclear phagocytes play key roles in tissue repair and remodeling. After infection or injury, these cells help in the clearance of dead cells and debris, a crucial step in the initiation of tissue remodeling and the resolution of inflammation. Overall, mononuclear phagocytes are versatile cells that have tailored their functions to meet the unique challenges of different tissues within the body. They are pivotal in homeostasis, immunity, and inflammation, making them important aspects in a range of human diseases including infection, autoimmunity, and cancer. |
