Weight Cycling Deregulates Eating Behavior in Mice via the Induction of Durable Gut Dysbiosis

Advanced Science, EarlyView.
Weight cycling in Humans is suspected to dysregulate eating behavior. Mice submitted to body weight cycling by alternating western‐type and regular chow diets display increased hedonic appetite when exposed to a palatable diet, reminiscent of binge‐eating episodes.

Dopaminergic presynaptic modulation of nigral afferents: its role in the generation of recurrent bursting in substantia nigra pars reticulata neurons

Frontiers in Systems Neuroscience, 2011
Previous work has shown the functions associated with activation of dopamine presynaptic receptors in some substantia nigra pars reticulata (SNr) afferents: i) striatonigral terminals (direct pathway) posses presynaptic dopamine D1-class receptors whose ...

The role of intracerebral dopamine D1 and D2 receptors in sleep‐wake cycles and general anesthesia

Ibrain, 2022
Dopamine (DA), a monoamine neurotransmitter, is synthesized and released mainly by neurons in the ventral tegmental area and the substantia nigra (SN) pars compacta of the midbrain.

Dopamine D1 Receptor Contributes to Glucocorticoid‐Associated Osteonecrosis of Femoral Head Protection Through the ATF3/CHOP Axis to Inhibit Osteoblastic Apoptosis

Advanced Science, EarlyView.
This work identifies a novel mechanism by which dopamine D1 receptor (DRD1) contributes to the pathogenesis of glucocorticoid (GC)‐associated osteonecrosis of the femoral head (ONFH) through the regulation of osteoblastic apoptosis, indicating that DRD1 serves as a critical mediator of the crosstalk between the nervous and skeletal systems.

Amphetamine Promotes Cortical Up State in Part Via Dopamine Receptors

Frontiers in Pharmacology, 2021
Cortical neurons oscillate between Up and Down states during slow wave sleep and general anesthesia. Recent studies show that Up/Down oscillations also occur during quiet wakefulness.

Blockade of adenosine A2A receptors prevents protein phosphorylation in the striatum induced by cortical stimulation [PDF]

, 2006
©2006 Society for NeurosciencePrevious studies have shown that cortical stimulation selectively activates extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation and immediate early gene expression in striatal GABAergic enkephalinergic neurons.

Bidirectional Interaction Between the Brain and Bone in Traumatic Brain Injury

Advanced Science, EarlyView.
Traumatic brain injury (TBI) disrupts the blood–brain barrier and activates neuroimmune responses, causing metabolic disturbances and long‐term bone mass loss. Concurrent fractures accelerate healing and enhance osteogenesis but disrupt regulatory mechanisms, leading to altered bone dynamics and exacerbating neuroinflammation, complicating recovery ...

Dopamine D2/3 occupancy of ziprasidone across a day : a within-subject PET study [PDF]

, 2013
Rationale Ziprasidone is an atypical antipsychotic recommended to be administered twice daily. Objectives The purpose of this study was to investigate whether occupancy of the dopamine D2/3 receptors by ziprasidone is maintained across a day ...
