Figure 2From: Simvastatin Inhibits Toll-like Receptor 8 (TLR8) Signaling in Primary Human Monocytes and Spontaneous Tumor Necrosis Factor Production from Rheumatoid Synovial Membrane CulturesSimvastatin inhibits TLR8 signaling in HEK Blue TLR8 cells, which is not reversed by treatment with GGPP. (A) HEK Blue TLR8 cells (which stably express TLR8 and a reporter gene expressing a SEAP under the control of a NF-κB/AP-1-inducible promoter) were cultured for 30 min in the presence of 10 µg/mL simvastatin ± 10 µmol/L GGPP, before stimulation with 5 µg/mL R-848 for 16 h. Supernatants were analyzed for SEAP activity by using the Quanti-Blue assay and cell viability (B) was measured by MTT assay. Data are representative of three independent experiments.Back to article page
