Glucose-Taurine Reduced Exerts Neuroinflammatory Responses by Inhibition of NF-κB Activation in LPS-Induced BV2 Microglia.

We want to find the anti-neuroinflammatory action of the taurine derivative Glucose-Taurine Reduced (G-T-R). The anti-neuroinflammatory action by G-T-R were investigated in lipopolysaccharide (LPS)-induced BV2 microglia. G-T-R inhibited the production of nitric oxide and prostaglandin E2, and down-regulated the protein expression of inducible NO synthase and cyclooxygenase-2. In addition, G-T-R reduced the cytokines secretion such as tumor necrosis factor (TNF-α), interleukin (IL) -1β and IL-6, in BV2 microglia treated with LPS. In addition, G-T-R dose-dependently decreased the activation of nuclear factor-kappa B. These findings confirmed the anti-neuroinflammatory activity of G-T-R, which may exert protective effects against neuroinflammatory-related diseases.
