BDNF and nervous system disorder: More specifically, we also found that the feces of mice fed with CPFs displayed regulated levels of metabolites that are involved in neurological diseases, including up-regulated levels of acetylcarnitine, adenine, daidzein, luteolin, and xanthurenic acid and down-regulated levels of agmatine and ganoderic acid A. For example, Kazak et al. reported that acetylcarnitine increased the concentration of BDNF in the brain and effectively attenuated LPS-induced neuroinflammation in the brain [55].
