Important information|
|
CD169, also known as Siglec-1 or sialoadhesin, is a cell surface receptor that is most frequently expressed by certain macrophage subsets in lymphoid tissue: the marginal metallophilic macrophages (MMMs) of the spleen and the macrophages in the subcapsular sinus and medulla of lymph nodes (1). To a lesser extent, CD169 is also found on macrophages in liver, lung and colon. CD169+ macrophages are involved in immunological tolerance, antigen presentation and defense against infectious agents such as viruses (2) and play a tumor-suppressive role in malignant tumors (3). In the intact brain, CD169 stains subpopulations of macrophages in the choroid plexus, leptomeninges and circumventricular organs (4). CD169 is regulated by contact with plasma proteins, and damage to the blood-brain barrier leads to the expression of CD169 on microglia and macrophages within the parenchyma (4).
