ApoE Production in Human Monocytes and Its Regulation by Inflammatory Cytokines
Figure 4
The role of TNF-α and the TNF-α antagonist, Enbrel, in regulating apoE production.
CD14+ cells (30×103 cells/well), positively selected from PBMC, were incubated for 20 hours in ELISpot plates in the presence of TGF-β (10 ng/ml) and Polymyxin B (10 µg/ml) with or without Enbrel (50 µg/ml). Black bars indicate apoE spot number without Enbrel and grey bars with Enbrel. Inflammatory cytokines were added at 10 ng/ml. Results shown are means ± SD of 4 donors. *** p<0.001, **p<0.01, ns: not significant.
