Figure 3. miR-466l Mediates Resolution-Phase Macrophage Polarization.
(A) M1 and M2 macrophages were obtained from human peripheral-blood mononuclear cells. VC and miR-466l were transfected into human macrophages for 72 hr (37°C). Phenotypes were assessed by flow cytometry after multicolor staining with fluorescent-conjugated antibodies. Relative fluorescence units (RFU) are normalized against VC and expressed as mean ± SEM from four independent experiments. *p < 0.05 and **p < 0.01, miR-466l versus VC.
(B) FVB mice were transfected with VC or miR-466l (48 hr) and then challenged with 1 mg Zym for 48 hr. Lavage peritoneal cells stained with three fluorescent-conjugated antibodies were analyzed by flow cytometry analysis. Representative flow cytometry histograms are shown. RFU are normalized against VC and expressed as mean ± SEM from four independent experiments. *p < 0.05 and **p < 0.01, versus VC.
