Effect of LPS and serum on cytokine release from alveolar macrophages, ATII and TT1 cells.

<p>Cells were exposed to LPS (1–100 ng/ml) in the presence and absence of serum for 24 hours. Conditioned media was then aspirated and TNFα, MCP-1 and IL-8 release measured by Luminex. Data expressed as mean ± SE (n = 6 subjects). **P<0.001, ***P<0.0002.
