Figure 1From: LPS induces IL-10 production by human alveolar macrophages via MAPKinases- and Sp1-dependent mechanismsTime and dose dependency of IL-10 production in HAM stimulated by LPS. HAM were stimulated with LPS (1 μg/ml) and supernatant were collected after different incubation time and assayed for IL-10 content by ELISA for Panel A and by real time PCR for Panel C. Panel B: HAM were stimulated for 24 hours with increasing concentration of LPS and supernatant were assayed for IL-10 by ELISA.Back to article page
