Figure Lengend Snippet: Rema alleviates LPS-induced release and increased expression levels of IL-1β, IL-6 and TNF-α in cultured Raw264.7 cells. (A) Experimental protocol using cultured Raw264.7 macrophages. (B) LPS induced alterations in the release of IL-1β, IL-6 and TNF-α in Raw264.7 cells, while treatment with Rema inhibited these LPS-mediated changes (n=3). (C) LPS induced alterations in the gene expression levels of IL-1β, IL-6 and TNF-α in Raw264.7 cells, while treatment with Rema inhibited these effects (n=3). (D) DAPA inhibited the LPS-induced release of IL-1β, IL-6 and TNF-α in Raw264.7 cells, while treatment with Rema did not affect the alterations induced by DAPA (n=3). *** P<0.001. DAPA, dapansutrile; LPS, lipopolysaccharide; ns, not significant; Rema, remimazolam; RT-qPCR, reverse transcription-quantitative PCR.
Article Snippet: Cells were cultured in DMEM without FBS and pre-treated with 100 μ g/ml Rema (diluted in DMEM) for 20 min, and subsequently treated with lipopolysaccharide (LPS; 0.5 μ g/ml diluted in DMEM; cat. no. HY-D1056H, MedChemExpress) for 24 h in incubator at 37°C.
