Spatial Frequency Selectivity Is Impaired in Dopamine D2 Receptor Knockout Mice

Frontiers in Integrative Neuroscience, 2018
Dopamine is a neurotransmitter implicated in several brain functions, including vision. In the present study, we investigated the impacts of the lack of D2 dopamine receptors on the structure and function of the primary visual cortex (V1) of D2-KO mice ...

WONOEP appraisal: Biomarkers and treatment strategies beyond the synapse

Epilepsia, EarlyView.
Abstract Epilepsy is a heterogeneous neurological disorder affecting more than 70 million people worldwide, posing significant challenges for clinicians due to its complex etiology, diverse manifestations, variable treatment responses, and the inability to predict seizures or disease onset reliably.

Dichotomous Dopaminergic Control of Ventral Pallidum Neurons

Frontiers in Cellular Neuroscience, 2018
The ventral pallidum (VP) is crucially involved in reward processing. Dopaminergic afferents reach the VP from the ventral tegmental area (VTA). Recent in vivo studies suggest dopamine application increase the firing in the VP.

Abnormal KCC2 expression and function in a mouse model of epilepsy and tuberous sclerosis complex

Epilepsia, EarlyView.
Abstract Objective Drug‐resistant epilepsy is a common, severe manifestation of the genetic disorder tuberous sclerosis complex (TSC). Although significant mechanistic and therapeutic advances have been made in TSC, treatments for seizures remain largely ineffective.

Dopamine D2 receptor upregulation in dorsal striatum in the LRRK2-R1441C rat model of early Parkinson’s disease revealed by in vivo PET imaging

Scientific Reports
We conducted PET imaging with [18F]FDOPA and dopamine D2/3 receptor ligand [18F]fallypride in aged transgenic rats carrying human pathogenic LRRK2 R1441C or G2019S mutations.

Dopamine presynaptically and heterogeneously modulates nucleus accumbens medium-spiny neuron GABA synapses in vitro

BMC Neuroscience, 2006
Background The striatal complex is the major target of dopamine action in the CNS. There, medium-spiny GABAergic neurons, which constitute about 95% of the neurons in the area, form a mutually inhibitory synaptic network that is modulated by dopamine ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Evidence for dopamine production and distribution of dopamine D2 receptors in the equine gastrointestinal mucosa and pancreas.

PLoS ONE
Insulin dysregulation in horses is characterised by hyperinsulinaemia and/or tissue insulin resistance and is associated with increased risk of laminitis.

Characterisation of AmphiAmR11, an amphioxus (Branchiostoma floridae) D2-dopamine-like G protein-coupled receptor.

PLoS ONE, 2013
The evolution of the biogenic amine signalling system in vertebrates is unclear. However, insights can be obtained from studying the structures and signalling properties of biogenic amine receptors from the protochordate, amphioxus, which is an ...

Neuronal Excitation in the Ventral Tegmental Area Modulates the Micturition Reflex Mediated via the Dopamine D1 and D2 Receptors in Rats

Journal of Pharmacological Sciences, 2003
Involvement of the dopamine D1 and D2 receptors in the ventral tegmental area (VTA) in the micturition reflex was investigated using female Sprague Dawley rats under urethane anesthesia.
