초록

Microglia, which is the primary immune effector cells in the central nervous system, constitutes the first line of defense against infection and injury in the brain. The goal of this study was to determine the protective (anti-inflammation) mechanisms of forsythia suspense (FS) on LPS-induced activation of BV-2 microglial cells. The effects of FS on gene expression profiles in activated BV-2 microglial cells were evaluated using microarray analysis. BV-2 microglial cells were cultured in a 100mm dish $(1{\times}10^7/dish)$ for 24hr and then pretreated with $1{\mu}g/mL$ FS or left untreated for 30 min. Next, $1{\mu}g/mL$ LPS was added to the samples and the cells were reincubated at $37^{\circ}C$ for 30 min, 1hr, and 3hr. The gene expression profiles of the BV-2 microglial cells varied depending on the FS. The oligonucleotide microarray analysis revealed that MAPK pathway-related genes such as Mitogen activated protein kinase 1 (Mapk1), RAS protein activator like 2 (Rasal2), and G-protein coupled receptor 12 (Gpr12) and nitric oxide biosynthesis-related genes such as nitric oxide synthase 1 (neuronal) adaptor protein (Nos1ap), and dimethylarginine dimethylaminohydrolase 1 (Ddah1) were down regulated in FS-treated BV-2 microglial cells. FS can affect the MAPK pathway and nitric oxide biosynthesis in BV-2 microglial cells.
