Epinephrine Enhances the Response of Macrophages under LPS Stimulation
Figure 4
Dose-dependent effect of epinephrine on CD14 expression from macrophages under LPS stimulation. The macrophages were pretreated with epinephrine at various concentrations (2 ng/mL, 10 ng/mL, 50 ng/mL, and 100 ng/mL) for 1 hour and then stimulated by 10 ng/mL LPS for another 1 hour. The expression level of CD14 in each group was measured by RT-PCR. The data were showed in (a) electrophoresis result and (b) semiquantitative analysis. , compared with the 0 ng/mL control group stimulated by LPS only.
