Figure 2From: Bench-to-bedside review: Adenosine receptors – promising targets in acute lung injury?AR-dependent pathways involved in PMN trafficking and fluid homeostasis during acute pulmonary inflammation. Presented is a three compartment model (capillary, interstitium, and alveolar space). Red indicates inhibitory effects, and green indicates stimulatory effects. AR, adenosine receptor; PMN, polymorphonuclear cell.Back to article page
