After 1 h, the infected animals were treated with AMPs or PBS also by intratracheal instillation (1 μg or 0.05 mg/kg of body weight), based on a small pilot experiment (data not shown) to determine minimum α4-short dosage protecting mice from a lethal infection at 1 h postexposure, as described in Materials and Methods. The gene discussed is ADSL; the disease is infection.
