Background: LYVE-1

LYVE-1 (Lymphatic Vessel Endothelial Receptor 1) is a receptor for the extracellular matrix mucopolysaccharide hyaluronan (HA) and is primarily expressed by lymphatic endothelial cells in addition to the sinusoidal endothelium of the liver and spleen (1-3). HA, also called hyaluronic acid, is a main component of the extracellular matrix and functions largely in cell adhesion, migration, and tissue remodeling (2). HA undergoes a turnover process that involves release from the tissues to the afferent lymph, degradation within the lymph nodes, and removal of fragments by the liver (2,3). LYVE-1, in addition to other lymphatic proteins including VEGFR3, Prox1, and podoplanin, is a common marker for differentiating between the blood and lymphatic systems (2,3). Furthermore, LYVE-1 is closely related to the leukocyte receptor CD44, having ~44% sequence similarity (1-3). Like CD44, the LYVE-1 protein contains an extracellular HA-binding link domain, with N- and C-terminal extensions, located at the end of a glycosylated juxtamembrane domain stalk region, followed by a transmembrane region, and a cytoplasmic tail (1-3). The key features of the HA-binding like molecule are the three disulfide bridges formed by six cysteine residues (1-3). LYVE-1 is synthesized as a protein of 322 amino acids in length with a theoretical molecular weight of 35 kDa, although due to O-glycosylation often appears in SDS-PAGE at a molecular weight ranging from ~60-70 kDa (2,4). The role of HA-binding is further elucidated by the identification of LYVE-1 as a docking receptor for dendritic cells and macrophages, binding their surface HA to control the entry and migration into lymph vessels (1).

LYVE-1 has been an important marker in studies of embryonic and tumor lymphangiogenesis, as many cancers are characterized by early metastasis to the lymph nodes (1-3, 5). One study of five different vascular tumors in infants used immunohistochemical analysis and found positive LYVE-1 expression in infantile hemangioma, tufted angioma, and kaposiform hemangioendothelioma (5). LYVE-1 along with other markers such as GLUT-1, CD31, CD34, Prox-1, and WT-1 can be used to help provide immunohistologic profiles of various tumors and, when used in conjunction with clinical and histopathologic approaches, may offer better overall diagnosis and disease treatment (5).
