Interaction between Intestinal Microbiota and Serotonin Metabolism
Gut microbiota regulates the production of signaling molecules, such as serotonin or 5-Hydroxytryptamine: 5-HT in the host. Serotonin is a biogenic amine that acts as a neurotransmitter in the gut and brain. There is a perfect interaction between human gastrointestinal microbiota and the serotonin system. The gut microbiota plays an important role in the serotonin signaling pathways through the...
متن کاملThe serotonin hypothesis in pulmonary hypertension revisited: targets for novel therapies (2017 Grover Conference Series)
Increased synthesis of serotonin and/or activity of serotonin in pulmonary arteries has been implicated in the pathobiology of pulmonary arterial hypertension (PAH). The incidence of PAH associated with diet pills such as aminorex, fenfluramine, and chlorphentermine initially led to the "serotonin hypothesis of pulmonary hypertension." Over the last couple of decades there has been an accumulat...
متن کاملSerotonin Signaling Through the 5-HT1B Receptor and NADPH Oxidase 1 in Pulmonary Arterial Hypertension
OBJECTIVE Serotonin can induce human pulmonary artery smooth muscle cell (hPASMC) proliferation through reactive oxygen species (ROS), influencing the development of pulmonary arterial hypertension (PAH). We hypothesize that in PASMCs, serotonin induces oxidative stress through NADPH-oxidase-derived ROS generation and reduced Nrf-2 (nuclear factor [erythroid-derived 2]-like 2) antioxidant syste...
متن کاملSerotonin increases susceptibility to pulmonary hypertension in BMPR2-deficient mice.
Heterozygous germline mutations in the gene encoding the bone morphogenetic protein type II (BMPR-II) receptor underlie the majority (>70%) of cases of familial pulmonary arterial hypertension (FPAH), and dysfunction of BMP signaling has been implicated in other forms of PAH. The reduced disease gene penetrance in FPAH indicates that other genetic and/or environmental factors may also be requir...
متن کاملEvidence for inflammatory signaling in idiopathic pulmonary artery hypertension: TRPC6 and nuclear factor-kappaB.
Knowledge of molecular mechanisms underlying pulmonary arterial hypertension (PAH) continues to increase with the emerging theme that PAH is a heterogeneous disease involving multiple molecular abnormalities. Mutations in several genes have been identified in subsets of patients with PAH, and multiple signaling systems that influence vascular tone, function, and remodeling have been associated ...
