| Research Abstract |
Midazolam is a widely-used sedative drug in critical care and anesthesia. We analyzed the effect of midazolam on the function of dendritic cells. Midazolam suppressed the functional maturation of dendritic cells by lipopolysaccharidein terms of the expression of costimulatory molecules and IL-12. Midazolam-treated dendritic cells inhibited the allostimulatory activity of dendritic cells. Midazolam-treated dendritic cells have reduced activity inducing contact hypersensitivity response, one of typical cell-mediated immune responses. It was suggested that these inhibitory effects of midazolam is mediated by the effect on peripheral benzodiazepine receptor (PBR) by the study using PBR-specific ligand.
