Pregnancy-specific glycoproteins: complex gene families regulating maternal-fetal interactions
1 Jan 2014
Abstract excerpt
The pregnancy-specific glycoproteins (PSGs) are the most abundant trophoblastic proteins in maternal blood during human pregnancy and they appear to be exclusive to species with hemochorial placentation. There are ten protein-coding human PSG genes (PSG1 - PSG9, PSG11) and also multiple PSG genes in non-human primates, rodents and bats. Several studies indicate that PSGs have immunoregulatory, pro-angiogenic, and...
