Leukocyte-associated immunoglobulin-like receptor 1 (LAIR1) is reduced with preeclampsia and small for gestational aged fetuses.

Leukocyte-associated immunoglobulin-like receptor 1 (LAIR1) is an inhibitory receptor expressed on immune cells. We evaluated LAIR1 in placentas from preeclamptic or small for gestational age (SGA) pregnancies, and placental explant model (1 % O, IL6 and TNFα, or control). LAIR1 mRNA was reduced in placentas from preeclamptic (p < 0.

Trophoblast Side-Population Markers are Dysregulated in Preeclampsia and Fetal Growth Restriction.

Dysregulated progenitor cell populations may contribute to poor placental development and placental insufficiency pathogenesis. Side-population cells possess progenitor properties. Recent human trophoblast side-population isolation identified enrichment of 8 specific genes (CXCL8, ELL2, GATA6, HK2, HLA-DPB1, INTS6, SERPINE3 and UPP1) (Gamage et al.

Plasma metabolites are altered before and after diagnosis of preeclampsia or fetal growth restriction.

Metabolomics is the study of small molecules (metabolites), within cells, tissues and biofluids. Maternal metabolites can provide important insight into the health and development of both mother and fetus throughout pregnancy. This study assessed metabolic profiles in the maternal circulation prior to and at the time of diagnosis of preeclampsia and fetal growth restriction.

Cell surface associated protein mucin 15 (MUC15) is elevated in preeclampsia.

Background: Mucins are a family of proteins that protect the epithelium. A particular type of mucin, MUC15 is highly expressed in the placenta. This study aimed to characterise MUC15 in preeclampsia and investigate its role in placental stem cell biology.
