Comment | Approximately 95% of the symbiotic microbes in human body are located in the gut. This microbioma is involved in important homeostatic processes, not only related to gastrointestinal function but also to several complex modulatory processes, such as glucose and bone metabolism, inflammation and immune response, peripheral (enteric) and central neurotransmission. |

Comment | The interactions with the central nervous system (CNS) occur within the so-called ‚Äėmicrobiota-gut-brain axis‚Äô, a complex and bidirectional communication network between the gut and the CNS. The gut microbiota effects on the brain are transduced by the activation of the vagus nerve, through the secretion of signaling molecules and the modulation of the immune system. The metabolic products of the healthy microbiome are required for the optimal function of the CNS microglia. |

Comment | Gut peptide hormones, such as ghrelin and leptin, are involved in the regulation of food intake and feeding behavior, being therefore implicated in energy homeostasis. Studies show that these factors also affect nervous functions, particularly learning and memory. Ghrelin is produced mainly by gastric oxyntic cells, devoid of contact with the gastrointestinal lumen, exerting therefore an endocrine role. Alternatively, this peptide is also produced by cells in the gastrointestinal tract with contact with the intestinal lumen, and therefore subject to the influence of the gut microbiota. |

Comment | The major substrate for the synthesis of serotonin is the essential aminoacid tryptophan. The largest part of bioavailable tryptophan is dedicated to the synthesis of kynurenine, an essential metabolic pathway that leads the production of nicotinamide adenine dinucleotide (NAD) both in human and microbiota cells. |

Comment | The gut microbiota regulates the availability of tryptophan by dislocating its uptake to the bacterial kynurenine pathway in detriment of serotonin synthesis by epithelial cells. Therefore, the gut microbiota, predominantly represented by Escherichia coli and Enterococci, plays an important role in the regulation of serotonin production, affecting the availability of this neurotransmitter both in enteric and central nervous systems. |

Comment | Gut peptide hormones, such as ghrelin and leptin, are involved in the regulation of food intake and feeding behavior, being therefore implicated in energy homeostasis. Studies show that these factors also affect nervous functions, particularly learning and memory. Ghrelin is produced mainly by gastric oxyntic cells, devoid of contact with the gastrointestinal lumen, exerting therefore an endocrine role. Alternatively, this peptide is also produced by cells in the gastrointestinal tract with contact with the intestinal lumen, and therefore subject to the influence of the gut microbiota. |
