Relative mRNA expression of chemokines and cytokines in the neonatal ovine lung. Exposure to ethanol in utero reduces mRNA expression of (A) TNF-α, (B) interleukin (IL)-10, (C) chemokine (C-C motif) ligand 5 (CCL5), (D) and monocyte chemotactic protein-1 (MCP-1) in the lungs of preterm (PT) lambs when compared with the control lambs of the same age group. In the lungs of full-term (FT) lambs, ethanol exposure in utero reduces mRNA expression of (A) TNF-α and (B) IL-10 (*P < .1, significance was established at 90% confidence interval).
