A Murine Model of Fetal Exposure to Maternal Inflammation to Study the Effects of Acute Chorioamnionitis on Newborn Intestinal Development
Published on: June 24, 2020
Abstract:
A 19-year-old woman who denied previous transfusion or pregnancy delivered a stillborn RhO(D)-positive male fetus at 38 weeks' gestation. IgG antibodies with the specificities anti-Rh0(D), anti-rh"(E), anti-Jka, and anti-Yta were eluted from the fetal red blood cells. In the maternal serum, the antiglobulin titer of anti-Rh0(D) was 1:20,000 and the saline (IgM) titer was 1:1,024. Amniocentesis findings at 36 weeks had suggested only mild, if any, fetal hemolysis, but the stillborn infant showed signs of severe hemolytic disease with cardiac failure. This case appears to represent an unusual augmented immune response to fetal red blood cell antigens.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
