摘要: 目的 观察α-突触核蛋白(α-synuclein, α-Syn)在正常食蟹猴消化道不同部位的表达。方法 利用免疫组织化学和Western blotting方法检测α-Syn在食蟹猴食道、胃、十二指肠、空肠、回肠及结肠中的表达特点和表达量。结果 α-Syn免疫活性物质主要见于消化道壁内神经的神经纤维和神经节,这些α-Syn免疫阳性神经结构见于消化道的黏膜、黏膜下层和肌层。在消化道的不同部位,α-Syn的表达量不同,其中十二指肠、空肠、回肠和结肠表达量较高,而胃和食道的表达量较低。结论 α-Syn主要存在于食蟹猴消化道的壁内神经,在消化道的不同部位表达量差异有统计学意义。

Abstract: Objective To investigate the expression of α-synuclein (α-Syn) in different regions of the digestive tract of cynomolgus monkeys. Methods Immunohistochemistry and Western blotting analysis were applied to observe the expression of α-Syn in the digestive tract of cynomolgus monkeys. Results α-Syn immunoreactive substances were observed in both the nerve fibers and nerve plexus in the wall of the digestive tract of cynomolgus monkeys. The α-Syn immunopositive structures were found in the mucosa, submucosal nerve plexus, and myenteric nerve plexus of the digestive tract. The amounts of α-Syn in different regions of the digestive tract were different, with the higher level of α-Syn found in the duodenum, jejunum, ileum, and colon, and lower levels of stomach and esophagus. Conclusion α-Syn is mainly localized in the intrinsic nerves in the digestive tract of cynomolgus monkeys, with the levels differing in different regions of the digestive tract.
