Excerpt
We read with great interest the article by Matsumoto et al. [
1] “Increased expression of 5-HT3 and NK-1 receptors in 5-fluorouracil-induced mucositis in mouse jejunum.” The preclinical study showed that during 5-fluorouracil treatment, the mouse jejunum showed a threefold increase in the expression of the neurokinin-1 receptor (NK-1R), NK-1 receptor mRNA, and NK-1R immunoreactivity profile in mucosal inflammation. NK-1 receptor immunopositive cells were also increased in the lamina propria, and the expression of NK-1 receptor immunoreactivity increased in the deep muscular plexus of the mouse jejunum. The study identified a role of substance P (SP)/NK-1R in mucosal inflammation during biological treatment. …
