A Hydrophobic Gate in an Ion Channel: The Closed State of the Nicotinic Acetylcholine Receptor [PDF]

open access: yesPhysical Biology, 3(2):147-159, 2006, 2005
The nicotinic acetylcholine receptor (nAChR) is the prototypic member of the `Cys-loop' superfamily of ligand-gated ion channels which mediate synaptic neurotransmission, and whose other members include receptors for glycine, gamma-aminobutyric acid, and serotonin.

Affective and cognitive prefrontal cortex projections to the lateral habenula in humans [PDF]

open access: yes, 2014
Anterior insula (AI) and dACC are known to process information about pain, loss, adversities, bad, harmful or suboptimal choices and consequences that threaten survival or well-being. Pain and loss activate also pregenual ACC (pgACC), linked to sad thoughts, hurt and regrets.

A Compound Screen Based on Isogenic hESC‐Derived β Cell Reveals an Inhibitor Targeting ZnT8‐Mediated Zinc Transportation to Protect Pancreatic β Cell from Stress‐Induced Cell Death

open access: yesAdvanced Science, EarlyView.
Pancreatic β cell loss by cellular stress contributes to diabetes pathogenesis. The study demonstrates that WFS1–ZnT8–zinc axis regulates vicious cycle of zinc transportation and cellular stress in pancreatic β cell. Based on that, the study applies a strategy for compound screening targeting ZnT8 based on human models, and identifies anisomycin, as a ...

Within‐day bidirectional associations between physical activity and affect: A real‐time ambulatory study in persons with and without depressive and anxiety disorders

open access: yesDepression and Anxiety, Volume 39, Issue 12, Page 922-931, December 2022., 2022
Abstract Background Ambulatory assessments offer opportunities to study physical activity level (PAL) and affect at the group and person‐level. We examined bidirectional associations between PAL and affect in a 3‐h timeframe and evaluated whether associations differ between people with and without current or remitted depression/anxiety.

Sustained Exposure to 3,4-Methylenedioxymethamphetamine Induces the Augmentation of Exocytotic Serotonin Release in Rat Organotypic Raphe Slice Cultures

open access: yesJournal of Pharmacological Sciences, 2010
3,4-Methylenedioxymethamphetamine (MDMA) causes serotonin efflux via serotonin transporter. Recently, we have reported that sustained exposure to MDMA induced an augmentation of serotonin release in rat raphe serotonergic slice cultures.

Direct serotonin release in humans shapes aversive learning and inhibition

open access: yesNature Communications
The role of serotonin in human behaviour is informed by approaches which allow in vivo modification of synaptic serotonin. However, characterising the effects of increased serotonin signalling in human models of behaviour is challenging given the ...

Decoding Blastocystis‐Driven Mechanisms in Gut Microbiota and Host Metabolism

open access: yesAdvanced Science, EarlyView.
Blastocystis, a prevalent gut microbe, interacts with the host through metabolic and immune pathways, influencing cardiometabolic health. This perspective explores its role in modulating short‐chain fatty acid production, tryptophan metabolism, and immune signaling, potentially impacting cholesterol absorption, glucose metabolism, and vascular health ...

The Role of Serotonin in the Influence of Intense Locomotion on the Behavior Under Uncertainty in the Mollusk Lymnaea stagnalis

open access: yesFrontiers in Physiology, 2020
The role of serotonin in the immediate and delayed influence of physical exercise on brain functions has been intensively studied in mammals. Recently, immediate effects of intense locomotion on the decision-making under uncertainty were reported in the ...
