CCL7 and acute respiratory distress syndrome: Neutralising either CCL2 (figure 2B) or CCL7 (figure 2C) also decreased neutrophil chemotaxis towards ARDS BAL fluid, but a combination of either anti-CXCL8 plus anti-CCL2 (figure 2B) or a combination of anti-CXCL8 plus anti-CCL7 (figure 2C) caused a cumulative decrease in the neutrophil chemotactic response to ARDS BAL fluid.
