serotoninergic function. In the periphery as well as in brain areas expressing TPH1, 5-HT synthesis is probably not restricted by Trp availability. In addition, a positive relationship between dietary Trp content and neural proliferation markers, such as exogenous 5-bromodeoxyuridine and brain derived neurotrophic factor BDNF has been demonstrated in rats 66 , which lends further support for the suggestion that dietary Trp can induce structural changes in the brain. For example, Tejpal et al. Accordingly, effects of dietary Trp on the neuroendocrine stress response have been reported in a variety of species, spanning from teleosts to humans 4 — In this review we will discuss the effect of manipulating tryptophan on mood and cognition, and discuss a possible influence of the gut-brain axis.
