KOREASCHOLAR

Taraxaci Herba has long been used in herbal medicine for their choleretic, anti-heumatic and diuretic properties. In the present study, we investigated the effects of origin plants of Taraxaci Herba, Taraxacum coreanum Nakai, as an anti-inflammatory agent in lipopolysaccharide(LPS)-induced microglial activation in BV2 cells. NNMBS273, the EtOH extracts of roots T. coreanum was examined for anti-neuronal inflammatory activity as new drug development. The roots of T. coreanum, showed the potent anti-neuroinflammatory effects on LPS-induced inflammation in microglial BV2 cells. The anti-inflammatory effects of NNMBS273, the EtOH extracts of roots T. coreanum was demonstrated by the suppression of pro-inflammatory mediators, including pro-inflammatory enzymes (inducible nitric oxide synthase and cyclooxygenase-2) and cytokines (tumor necrosis factor-α and interleukin-1β). These results suggest that the roots T. coreanum may be a promising candidate for the treatment of neurodegenerative diseases related to neuroinflammation.
