Designing Effective Multi-Target Drugs and Identifying Biomarkers in Recurrent Pregnancy Loss (RPL) Using In Vivo, In Vitro, and In Silico Approaches

Biomedicines, 2023
Recurrent pregnancy loss (RPL) occurs in approximately 5% of women. Despite an abundance of evidence, the molecular mechanism of RPL’s pathology remains unclear. Here, we report the protective role of polo-like kinase 1 (PLK1) during RPL.

Human placental cytotrophoblasts produce the immunosuppressive cytokine interleukin 10. [PDF]

, 1996
The mechanism by which the mammalian mother accepts the implanting fetus as an allograft remains unexplained, but is likely to be the result of a combination of factors.

Optimal villi density for maximal oxygen uptake in the human placenta

, 2015
We present a stream-tube model of oxygen exchange inside a human placenta functional unit (a placentone). The effect of villi density on oxygen transfer efficiency is assessed by numerically solving the diffusion-convection equation in a 2D+1D geometry ...

Increased incidence of cytogenetic abnormalities in chorionic villus samples from pregnancies established by in vitro fertilization and embryo transfer (IVF-ET) [PDF]

, 1995
We studied 201 pregnancies that were established by in vitro fertilization and embryo transfer (IVF–ET) and compared the frequency of cytogenetic abnormalities with that found in a large control population matched for indication group (advanced maternal ...

HRS Degradation‐Induced Nicotinamide Deficiency in Placental Extracellular Vesicles Triggers Preeclampsia by Disrupting Maternal‐Fetal Immune Homeostasis

Advanced Science, EarlyView.
This study shows that lower NAM levels in PE‐derived pEVs correlate with disease severity. NAM‐deficient pEVs reduce Th1 and Th17 inhibition, leading to PE‐like symptoms. NAM in pEVs inhibits Th1 via SIRT1 and Th17 via macrophages. Reduced NAM in PE‐EVs is due to decreased HRS expression in trophoblasts, resulting from elevated HSP27.

Computational fluid dynamic simulations of maternal circulation : wall shear stress in the human placenta and its biological implications [PDF]

, 2016
Introduction In the human placenta the maternal blood circulates in the intervillous space (IVS). The syncytiotrophoblast (STB) is in direct contact with maternal blood.

Localization of matrix metalloproteinases in the placenta of cows with complicated pregnancy by placental insufficiency [PDF]

BIO Web of Conferences
The placenta of 8 cows with physiological (PP) and placental insufficiency pregnancy (FPI) served as the material for the study. Analysis of the content of glycosaminoglycans (GAG) in the tissue of the uterine part of the placenta in cows with FPI ...

Caspase‐3/GSDME‐Mediated Trophoblast Pyroptosis and Reciprocal Macrophage Polarization Contribute to Inflammation in Early‐Onset Preeclampsia

Advanced Science, EarlyView.
In trophoblast cells, T/S (TNFα + SM164) activated caspase‐3, which cleaved GSDME to switch apoptosis to pyroptosis, causing cell swelling, membrane rupture, and release of LDH, HMGB1, IL‐1β and IL‐18. These cytokines induced pro‐inflammatory macrophage polarization, which in turn reinforced pyroptotic signaling in trophoblasts, amplifying systemic ...

Syncytiotrophoblast of Placentae from Women with Zika Virus Infection Has Altered Tight Junction Protein Expression and Increased Paracellular Permeability

Cells, 2019
The cytotrophoblast of human placenta transitions into an outer multinucleated syncytiotrophoblast (STB) layer that covers chorionic villi which are in contact with maternal blood in the intervillous space. During pregnancy, the Zika virus (ZIKV) poses a

Placental Structure in Preterm Birth Among HIV-Positive Versus HIV-Negative Women in Kenya. [PDF]

, 2019
BackgroundPreterm birth (PTB) is a major cause of infant morbidity and mortality in developing countries. Recent data suggest that in addition to Human Immunodeficiency Virus (HIV) infection, use of antiretroviral therapy (ART) increases the risk of PTB.
