Figure 1From: Dynamics of pro-inflammatory and anti-inflammatory cytokine release during acute inflammation in chronic obstructive pulmonary disease: an ex vivo studyKinetics of the acute inflammatory response in human lung tissue. Human lung tissue (n = 37) was stimulated with 100 ng/ml LPS (filled circles) or buffer control (open circles). The release of (A) TNFα and (B) IL-1β into the supernatant was measured by commercial ELISA. Values shown are the mean ± SEM and are expressed as pg/mg of tissue, * indicates a p value < 0.05.Back to article page
