| Outline of Final Research Achievements |
In the acute spinal injury, we must try to minimize the inflammation of the spinal cord tissue. We try to rescue this inflammation and investigate the mechanism to suppress the microglia for minimizing the inflammation. The ghrelin system activated by Rikkunshito significantly reduced the number of pathologically activated microglia with amoeboid morphology in the brains of klotho-deficient, SAMP8 and aged ICR mice. We also report that SGK1 and SGK3 are expressed in multiple microglial cell lines. An SGK inhibitor, gsk650394, inhibits cell viability. In addition, lipopolysaccharide-induced expression of inflammatory regulators iNOS and TNFa was enhanced by gsk650394. These findings suggest that SGKs may play an important role in regulating microglial viability and inflammatory responses. These two investigations include the important findings to rescue this inflammation of the spinal cord tissue.
