abstract：:Because interleukin 8 (IL-8) is a potent neutrophil chemotactic and activating cytokine, we investigated IL-8 production in relation to neutrophil migration and elastase release in the human lung during unilateral community-acquired pneumonia (CAP). In 17 patients, the local response in the involved lung was compared ...
