Biological clocks in the duodenum and the diurnal regulation of duodenal and plasma serotonin. [PDF]

open access: yesPLoS ONE, 2013
Serotonin in blood plasma is primarily synthesized in the duodenum, as brain derived serotonin does not cross the blood-brain barrier. Because serotonin in the brain and retina is synthesized under the control of a circadian clock, we sought to determine

Signaling pathways linking behavior to neurogenesis in healthy brain and disease [PDF]

open access: yes, 2020
Self-repair of the adult brain is limited – most diseases lack effective therapy. In order to better understand how a regenerative response can be achieved, studying mechanisms shaping the neurogenic niche, from environmental factors to intrinsic ...

Serotonin modulates Campylobacter jejuni physiology and in vitro interaction with the gut epithelium

open access: yesPoultry Science, 2021
Microbial endocrinology, which is the study of neurochemical-based host–microbe interaction, has demonstrated that neurochemicals affect bacterial pathogenicity.

Modulation of tryptophan/serotonin pathway by probiotic supplementation in human immunodeficiency virus-positive patients: preliminary results of a new study approach [PDF]

open access: yes, 2017
Background: To date, no data are available regarding the effects of probiotics on the pathway of tryptophan/serotonin metabolism among human immunodeficiency virus (HIV) 1–infected individuals.

Serotonergic agents and linezolid: Impact of exposure to more than one agent concomitantly on risk of adverse effects

open access: yesAntimicrobial Stewardship & Healthcare Epidemiology, 2023
Background: The off-target effects linezolid have the potential to cause serotonin syndrome when given in conjunction with serotonergic agents. Despite package insert labeling as a contraindication, several postmarketing studies have demonstrated a low ...

Serotonin Receptors: Genetic insights into serotonin function [PDF]

open access: yesCurrent Biology, 1995
Targeted disruption of the genes for the 5-HT1B and 5-HT2C serotonin receptors and monoamine oxidase A have confirmed pharmacological experiments and revealed unexpected behavioral roles for serotonin.

Female genital disorder as adverse symptom of lamotrigine treatment - A serotoninergic effect? [PDF]

open access: yes, 1998
The new anticonvulsant, lamotrigine, is becoming an important tool in the treatment of bipolar disorder, including bipolar depression. Its efficacy in bipolar depression might be linked to its inhibition of serotonin uptake.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The effects of glycogen synthase kinase-3beta in serotonin neurons. [PDF]

open access: yesPLoS ONE, 2012
Glycogen synthase kinase-3 (GSK3) is a constitutively active protein kinase in brain. Increasing evidence has shown that GSK3 acts as a modulator in the serotonin neurotransmission system, including direct interaction with serotonin 1B (5-HT1B) receptors

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...
