To test whether S100a8/a9-priming of the neonatal gut can counteract the strong imprinting effect of maternal malnutrition and prevent enteropathy development, neonates from MN dams were fed a single dose of S100a8 within the first 24 h after birth (Fig. 4a). This evidence concerns the gene IGKV1D-22 and Abnormal intestine morphology.
