| Research Abstract |
Sialic acid is increased in serum and spinal fluid of CNS disease patients. Therefore to examine effects of sialic acid in pathophysiological situation, following are examined: 1) An effect of sialic acid on a function of microglia was performed. Desialylation on microglia induced significant expressions of inflammatory cytokines. 2) An effect of sialic acid on function of neuron was performed. Desialylation on neuron required for significant neurite outgrowth by neurite inducers. 3) An effect of desialylation in the brain was performed. Desialylation induced significant microglial activation and neuronal loss, indicating that desialylation induced neuronal damage which might be correlated with CNS disease.
