Activation of D1 and D2 dopamine receptors increases the activity of the somatostatin receptor-effector system in the rat frontoparietal cortex [PDF]

, 2000
The role of dopamine D1 and D2 receptor subtypes in the regulation, in vivo, of the somatostatin (SRIF) receptor-effector system in rat frontoparietal cortex was investigated.

Preclinical models for evaluating psychedelics in the treatment of major depressive disorder

British Journal of Pharmacology, EarlyView.
Psychedelic drugs have seen a resurgence in interest as a next generation of psychiatric medicines with potential as rapid‐acting antidepressants (RAADs). Despite promising early clinical trials, the mechanisms which underlie the effects of psychedelics are poorly understood.

The Fat Mass and Obesity-Associated Protein (FTO) Regulates Locomotor Responses to Novelty via D2R Medium Spiny Neurons

Cell Reports, 2019
Summary: Variations in the human FTO gene have been linked to obesity and altered connectivity of the dopaminergic neurocircuitry. Here, we report that fat mass and obesity-associated protein (FTO) in dopamine D2 receptor-expressing medium spiny neurons (

Altered brainstem responses to modafinil in schizophrenia: implications for adjunctive treatment of cognition. [PDF]

, 2018
Candidate pro-cognitive drugs for schizophrenia targeting several neurochemical systems have consistently failed to demonstrate robust efficacy. It remains untested whether concurrent antipsychotic medications exert pharmacodynamic interactions that ...

Neuropsychopharmacology of hallucinogenic and non‐hallucinogenic 5‐HT2A receptor agonists

British Journal of Pharmacology, EarlyView.
Psychedelic drugs such as LSD and psilocin were once relegated to the fringes of medical research because of their association with counterculture movements and a perceived concern about harm through recreational use, and their consequent legal prohibition in the early 1970s.

Kappa-opioid receptor signaling in the striatum as a potential modulator of dopamine transmission in cocaine dependence

Frontiers in Psychiatry, 2013
Cocaine addiction is accompanied by a decrease in striatal dopamine signaling, measured as a decrease in dopamine D2 receptor binding as well as blunted dopamine release in the striatum. These alterations in dopamine transmission have clinical relevance,

Changes in Dopamine Signalling Do Not Underlie Aberrant Hippocampal Plasticity in a Mouse Model of Huntington's Disease [PDF]

, 2016
Altered dopamine receptor labelling has been demonstrated in presymptomatic and symptomatic Huntington's disease (HD) gene carriers, indicating that alterations in dopaminergic signalling are an early event in HD.

Dopamine-modulated dynamic cell assemblies generated by the GABAergic striatal microcircuit [PDF]

, 2009
The striatum, the principal input structure of the basal ganglia, is crucial to both motor control and learning. It receives convergent input from all over the neocortex, hippocampal formation, amygdala and thalamus, and is the primary recipient of ...

Psychedelics, entactogens and psychoplastogens for depression and related disorders

British Journal of Pharmacology, EarlyView.
Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N‐dimethyltryptamine, ayahuasca; non‐hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g.

D2-like dopamine receptors mediate the response to amphetamine in a mouse model of ADHD

Neurobiology of Disease, 2007
The mechanisms underlying the effects of psychostimulants in attention deficit hyperactivity disorder (ADHD) are not well understood, but indirect evidence implicates D2 dopamine receptors. Here we dissect the components of dopaminergic neurotransmission
