Understanding vulnerability for depression from a cognitive neuroscience perspective: a reappraisal of attentional factors and a new conceptual framework [PDF]

open access: yes, 2010
We propose a framework to understand increases in vulnerability for depression after recurrent episodes that links attention processes and schema activation to negative mood states, by integrating cognitive and neurobiological findings.

Unraveling Persistent Genital Arousal Disorder—A Case Report on Innovative Therapeutic Approaches

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Persistent genital arousal disorder (PGAD) is a rare and distressing condition characterized by persistent, unwanted genital arousal in the absence of sexual desire, often leading to significant psychological distress and functional impairment.

Activation of G protein-coupled receptors entails cysteine modulation of agonist binding [PDF]

open access: yes, 1998
The increase of the affinity of agonists with an increase in pH and experiments using thiol-specific reagents indicate that G protein-coupled receptors contain an ionizable cysteine residue at the ligand binding site.

Serotonin 5-HT2A and 5-HT2C receptors differentially modulate the acquisition and expression of voluntary alcohol drinking in male mice

open access: yesFrontiers in Neuroscience
IntroductionStudies suggest that serotonin (5-HT) plays an important role in alcohol use disorder (AUD). While several receptor subtypes modulate the role of 5-HT in AUD, evidence suggests that 5-HT2A and 5-HT2C receptors may be directly involved in ...

Influence of mirtazapine on salivary cortisol in depressed patients [PDF]

open access: yes, 2003
Unlike other antidepressants, mirtazapine does not inhibit the reuptake of norepinephrine or serotonin but acts as an antagonist at presynaptic alpha(2)-receptors, at postsynaptic 5-HT2 and 5-HT3 receptors, and at histaminergic H1 receptors. Furthermore,

A Single Dose of LSD Does Not Alter Gene Expression of the Serotonin 2A Receptor Gene (HTR2A) or Early Growth Response Genes (EGR1-3) in Healthy Subjects

open access: yesFrontiers in Pharmacology, 2017
Rationale: Renewed interest has been seen in the use of lysergic acid diethylamide (LSD) in psychiatric research and practice. The repeated use of LSD leads to tolerance that is believed to result from serotonin (5-HT) 5-HT2A receptor downregulation.

Citalopram plus low-dose pipamperone versus citalopram plus placebo in patients with major depressive disorder: an 8-week, double-blind, randomized study on magnitude and timing of clinical response [PDF]

open access: yes, 2011
Background: Selective serotonin reuptake inhibitors take several weeks to achieve their full antidepressant effects. Post-synaptic 5-HT<sub>2A</sub> receptor activation is thought to be involved in this delayed therapeutic effect ...

Functional brain imaging : a brief overview of imaging techniques and their use in human and canine anxiety research [PDF]

open access: yes, 2011
When used in combination with specific radioactive markers, functional imaging modalities such as Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) enable the visualization of several neurotransmitter receptors and

Serotonin reuptake inhibitors and cardiovascular disease [PDF]

open access: yes, 2005
Selective serotonin re-uptake inhibiting drugs (SSRIs) are widely used for endogenous depression. In addition to depleting the nerve terminals of serotonin they also lower blood platelet serotonin levels.

The 5-HT2A receptor antagonist M100907 produces antiparkinsonian effects and decreases striatal glutamate

open access: yesFrontiers in Systems Neuroscience, 2011
5-HT plays a regulatory role in voluntary movements of the basal ganglia and have a major impact on disorders of the basal ganglia such as Parkinson’s disease (PD).
