Moreover, one of the pathological features of ALI includes uncontrolled inflammatory response during immune and neutrophil movement (29), a process that is in part shown to be controlled by NK cells through producing pulmonary CXCL1 and CXCL2 (30); however, NK cell’s function and factors influencing its activity in ALI are still underestimated. The gene discussed is CXCL2; the disease is acute respiratory distress syndrome.
