(A) IL-8 dose response and (B) linear regression analysis from paired nasal and bronchial epithelial cells from COPD subjects after 24 h treatment with LPS.

Abstract

<p>Paired nasal and bronchial epithelial cells were with various concentrations of LPS [5–25 µg/ml] for 24 h (n = 8). Supernatants were collected and assessed for IL-8 by ELISA in all cases. Data are displayed as median (interquartile range). * indicates a significant difference (<i>p</i><0.05).</p
