Zusammenfassung
Rationale: Severe pneumococcal pneumonia frequently causes respiratory failure. Both pathogen factors and an uncontrolled host response may contribute to acute lung injury (ALI) by impairing microvascular barrier function. Objectives: To analyze phosphodiesterase 2 (PDE2) as a potential target in pneumonia-induced lung microvascular hyperpermeability. Methods: HUVECs and isolated mouse lungs were challenged with the pneumococcal exotoxin pneumolysin in the presence or absence of the selective PDE2 inhibitors PDP or PDP-2. Transcellular electrical resistance or human serum albumin (HSA) leakage in bronchoalveolar…
