Activated microglia-mediated inflammation promotes neuronal damage under cerebral hypoxic-ischemic conditions, so it is likely that inhibiting hypoxia-induced activation of microglia will alleviate neuronal damage. To test this hypothesis, Dr. Lining Ke and co-workers from Southern Medical University and Fujian Medical University in China co-cultured ginsenoside Rb1, an active component of ginseng, and cortical neurons. Their findings indicate that ginsenoside Rb1 attenuates damage to cerebral cortex neurons by downregulation of nitric oxide, superoxide, and tumor necrosis factor-α expression in hypoxia-activated microglia. This study, which has been published in the Neural Regeneration Research (Vol. 9, No. 3, 2014), suggest that ginsenoside Rb1 is a promising candidate for clinical use in the prevention of neuronal degeneration following cerebral ischemia.
