Histologically, Ly-GDI expression attenuates IgG immune complex-induced acute lung inflammation.

<p>Adeno-GFP or Adeno-Ly-GDI was injected to mice <i>via</i> an airway instillation at a dose of 5 × 10⁸ PFU. 3 days later, the mice were subjected to IgG immune complex-induced lung injury or control treatment (αBSA only). Lungs were harvested 4 h later, and lung sections were stained with H & E (40 × magnification). Lung sections shown included: Adno-GFP + anti-BSA (A), Adeno-GFP + IgG IC (B), Adeno-Ly-GDI + anti-BSA (C), and Adeno-Ly-GDI + IgG IC (D). Scale bar, 60 μm.
