Involvement of KC in the mechanical ventilation-induced inflammatory response. Pulmonary neutrophil counts expressed as the number of neutrophils per square centimetre tissue and IL-1β concentration expressed as picogram cytokine per millilitre lung homogenate. Data are expressed as box-and-whiskers plots, with min to max range as whiskers. Pulmonary neutrophils and IL-1β concentration in the non-ventilated (C) and ventilated (V) untreated wild-type mice (WT) and anti-KC antibody-treated wild-type (anti-KC) mice are shown. *p < 0.05.
