mortality/aging
• lethality after birth, with no mice surviving post-weaning

respiratory system
• abnormal cilia morphology and shorter cilia in the P1.5 main bronchus
• less abundant cilia in the P1.5 main bronchus
• inflammation in the neonatal lung
• mononuclear cells appear in alveolar spaces more often than in controls
• lungs show lower levels of phosphatidylcholine, but not phosphatidylgycerol
• abnormal lamellar body formation
• at P1.5, collapsed regions in the lungs are detected
• atelectasis is progressive
• 93.1% of mice that die between P0.5 and P1.5 have macroscopic atelectasis while 48.3% of the surviving mice have atelectasis
• type II alveolar epithelial cells exhibit impairment of the processing of surfactants

homeostasis/metabolism
• neonatal mice become cyanotic immediately after delivery and all die within 10 days
• levels of phosphatidylcholine, but not phosphatidylgycerol, are lower in the lungs
• P1.5 mice show increased levels of pro-inflammatory and anti-inflammatory cytokines and various CC chemokines and CXC chemokines mRNAs
• 5.4-fold increase in IL-1alpha mRNA at P1.5
• 4.9-fold increase in TNF-beta mRNA at P1.5
• 11.5-fold and 16-fold increase in Ccl4/MIP1beta and Cxcl2/MIP-2 mRNA at P1.5

immune system
• P1.5 mice show increased levels of pro-inflammatory and anti-inflammatory cytokines and various CC chemokines and CXC chemokines mRNAs
• 5.4-fold increase in IL-1alpha mRNA at P1.5
• 4.9-fold increase in TNF-beta mRNA at P1.5
• 11.5-fold and 16-fold increase in Ccl4/MIP1beta and Cxcl2/MIP-2 mRNA at P1.5
• inflammation in the neonatal lung
• mononuclear cells appear in alveolar spaces more often than in controls

cellular
