Beschreibung von PSG6 / PSG10 Protein

PSG6 is a member of pregnancy-specific glycoproteins (PSGs) which are a group of molecules that are mainly produced by the placental syncytiotrophoblasts during pregnancy. PSGs comprise a subgroup of the carcinoembryonic antigen (CEA) family, which belongs to the immunoglobulin superfamily. PSGs play a critical role in pregnancy success. PSGs regulate T-cell function. The regulation of T-cell function during pregnancy is likely the result of significant hormonal changes and may well involve immunoregulatory proteins derived from the placenta. PSGs are the most abundant placentally derived glycoproteins in the maternal serum. PSG1, PSG6, PSG6N, and PSG11 induce dose-dependent secretion of anti-inflammatory cytokines by human monocytes. Human and murine PSGs exhibit cross-species activity. Low PSG levels in the maternal circulation are associated with threatened abortions, intrauterine retardation and fetal hypoxia. Also, PGSs may participate in maternal vasculature remodeling through influencing on secretion of proangiogenic agents such as transforming growth factor-beta-1 (TGF-β1) and vascular endothelial growth factor (VEGF) by different cell types involved in the development of placenta.
