Cao J, Wu T, Zhang L (2014) [Targeted damage of the cerebrospinal fluid-contacting nucleus contributes to the pain behavior and the expression of 5-HT and c-Fos in spinal dorsal horn of rats]. Zhongguo Ying Yong Sheng Li Xue Za Zhi 30:218-222.

Summary: Pain threshold, 5-hydroxytryptamine (5-HT) expression, and c-Fos expression were measured in rats after treatment with CTB-SAP (Cat. #IT-14). Use of CTB-SAP reduced the number of neurons in the cerebrospinal fluid (CSF)-contacting nucleus over time until no neurons could be detected by the 10th day post-injection. 5-HT and c-Fos expression in the spinal dorsal horn gradually increased, and was negatively correlated with the pain threshold. The data indicate that neurons in the CSF-contacting nucleus are involved in pain regulation, and that expression of 5-HT and c-Fos is part of this regulatory pathway.
