Abstract
En 中文
• Humanized (hChia) mice recapitulate common human AMCase activity variants in vivo • Basal lung inflammatory tone is elevated in low-activity hChia mice • Allergic, viral, and fibrotic lung disease is exacerbated in low-activity hChia mice • Chitinase reduces inflammatory effects of chitin from patients with acute lung injury
