Figure 8From: Differential cell reaction upon Toll-like receptor 4 and 9 activation in human alveolar and lung interstitial macrophages LPS-induced cytokine secretion. AM or IM were left untreated (Co) or treated with LPS (100 ng/ml) for 6 h. Supernatants were removed and used for measurement of cytokine protein production. Data are normalized to total cellular protein values. Data show means ± SEM of 2-4 independent experiments performed in triplicate with cells derived from different donors. *P < 0.05.
