Results

Dex enhances LPS-induced expression of Lcn2 and PTX3 in macrophages:

Consistent with previous observations (30, 31), Dex suppressed expression of the NF-B-regulated cytokine genes Il6 (encoding IL-6) and Il12b (encoding IL-12 p40) in LPS-stimulated BMMs at both mRNA (Fig. 1A) and protein levels (Fig. 1B). Although LPS elicits expression of Lcn2 and Ptx3 via NF-B activation in macrophages (11, 13, 18, 32, 33), little is known whether Dex affects LPS-induced expression of Lcn2 and Ptx3. …
