Bone marrow cells were isolated from C57BL/6 mice and cultured in
RPMI 1640 media (GIBCO) supplemented with 10% heat inactivated
FBS (BioInd), 1%
penicillin/streptomycin (Beyotime), 20 ng/mL of
IL-4 (Peprotech)and 20 ng/mL of
GM-CSF (Peprotech) at 37 C and 5% CO 2 . Non-adherent cells were harvested on day 7 and used immediately. DC purity was confirmed with
PE labeled antimouse CD11c (Biolegend) by FACS, consistently found to be > 90% CD11c + .
In vitro BMDC stimulation Immature BMDCs (5 3 10 4 ) were planted onto 96 well plates, then treated with simvastatin (1 mM) or LPS (100 ng/mL) for 24 h. The cell supernatants IL-6 was measured by
mouse IL-6 ELISA kit (Ebioscience), TNF-a was measured by
mouse TNF-a ELISA kit (Ebioscience) and IL-12p70 was measured by mouse IL-12p70 ELISA kit (Ebioscience) according to the manufacturer's instructions. Cell-surface co-stimulatory molecules and MHC-II were detected by
FITC labeled anti-mouse CD80 (Biolegend),
anti-mouse CD86 (Biolegend) and
PE labeled anti-mouse MHC-II (Ebioscience).
