Study Title | Pulmonary maternal immune activation does not extend through the placenta but leads to fetal metabolic adaptation - Maternal liver |
Study Summary | Maternal immune system activation (MIA) during pregnancy can disrupt the fetal environment, causing postnatal susceptibility to disorders. How the placenta and the fetus respond to acute MIA over time is unknown. Here, we characterized the response to acute maternal pulmonary inflammation across time in maternal and fetal organs using multi-omics. Unlike maternal organs which mounted strong innate immune responses, the placenta upregulated tissue-integrity genes, likely to prevent fetal exposure to infections, and downregulated growth-associated genes. Subsequently, the placenta upregulated biosynthesis and endoplasmic reticulum stress genes in order to return to homeostasis. These responses likely protected the fetus, since we observed no immune response in fetal liver. Instead, likely due to nutrient depletion, the fetal liver displayed metabolic adaptations, including increases in lipids containing docosahexaenoic acid, crucial for fetal brain development. Our study shows, for the first time, the integrated temporal response to pulmonary MIA across maternal and fetal organs. |

Sample Preparation:
Sampleprep ID: | SP003253 |
Sampleprep Summary: | Lipids were extracted from fetal liver samples (20 mg) using Folch extraction* with 8-12 replicates from each experimental group at each time point. Prior to tissue lysis, Splash mix (Merck) was added to the extraction solvent and tissue samples were lysed by beat beating in a FastPrep-24 homogenizer. After centrifugation and phase separation, the apolar and polar phases were transferred to separate tubes, and the apolar phase dried under N2. *Folch, J., Lees, M. & Sloane Stanley, G. H.
