The effect of cAMP on IgG-IC-induced pulmonary recruitment of inflammatory cells. Mice are treated by intraperitoneal injection of DMSO or Rolipram (1 mg/kg), which is followed by immediate airway deposition of IgG-IC. 4 h later, BAL fluids are harvested, and total white blood cells (A), neutrophils (B), and macrophages/monocytes (C) are counted, respectively. Data are expressed as mean ± SEM (N = 6 for control groups, and N = 10 for IgG-IC-treated groups). *** suggests p < 0.001
