摘要: 目的 研究寡聚化和磷酸化α-突触核蛋白(α-synuclein,α-Syn)在食蟹猴结肠和脑中的增龄性变化及其相关性。方法 ELISA方法检测寡聚化和磷酸化α-Syn在不同年龄段食蟹猴结肠与脑中不同部位含量的变化,分析结肠和脑中寡聚化和磷酸化α-Syn含量变化的相关性。结果 寡聚化与磷酸化α-Syn含量随年龄增加而增加,其中老年猴与青年及中年猴比较,差异有统计学意义(P<0.01)。结肠中的寡聚化和磷酸化α-Syn水平与颞叶、海马、纹状体和丘脑中的水平有相关性。结论 食蟹猴结肠和脑中寡聚化和磷酸化α-Syn含量随老化而增加,结肠和脑中寡聚化和磷酸化α-Syn含量变化呈正相关。

Abstract: Objective To explore age-dependent alterations in oligomeric and phosphorylated α-synuclein(o-α-Syn and p-α-Syn) in the colon and brain, analyze the correlation for levels of o-α-Syn and p-α-Syn between the colon and different regions of the brain.Methods ELISA methods specific for o-α-Syn and p-α-Syn were used to measure the levels of o-α-Syn and p-α-Syn in the colon and brain of different ages of cynomolgus monkeys. Results Levels of o-α-Syn and p-α-Syn increased significantly with age in the colon and brain, statistically significant difference was observed between the old monkeys and the young and middle-aged monkeys (P< 0.01). Levels of o-α-Syn and p-α-Syn in the colon were positively correlated with those in the temporal lobe, hippocampus, striatum and thalamus of the brain.Conclusion Levels of o-α-Syn and p-α-Syn increase with age in the colon and brain and positively correlated between the colon and some vulnerable brain regions.
