Abstract

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.
