From Belly to Brain: Targeting the Ghrelin Receptor in Appetite and Food Intake Regulation

Improving the ability of ghrelin ligands to penetrate the blood brain barrier would enhance central delivery to GHSR-1a expressing brain regions, particularly within the mesolimbic reward circuitry.

The Antidepressant-like Effects of Estrogen-mediated Ghrelin

Ghrelin, one of the brain-gut peptides, stimulates food-intake. Recently, ghrelin has also shown to play an important role in depression treatment. However, the mechanism of ghrelin’s

Ghrelin and Neurodegenerative Disorders—a Review

This review aims to provide a comprehensive overview of the most recent evidence of the novel neuromodulatory role of ghrelin in PD, AD, and HD.

[Ghrelin: a gastric hormone at the crossroad between growth and appetite regulation].

Ghrelin is a 28 amino acid peptide hormone synthesized within the gastrointestinal tract. Initially identified as the endogenous ligand of the GHS-R1a (Growth Hormone Secretagogue Receptor 1a),

Ghrelin Affects Certain Forms of Learning and Memory in both Rats and Mice

It is found that the micro infusion of ghrelin into the LA or the CA1 interfered with certain types of learning and memory in both rats and mice, suggesting that gh Relin affectslearning and memory.

Ghrelin triggers the synaptic incorporation of AMPA receptors in the hippocampus

It is proposed that GHS-R1a activation in the hippocampus enhances excitatory synaptic transmission and synaptic plasticity by regulating AMPAR trafficking and suggests a possible link between the regulation of energy metabolism and learning.

Physiological Effect of Ghrelin on Body Systems

It is found that ghrelin has effect on all body systems and its application as a GHSR agonist to treat most common diseases in each system without any paradoxical outcomes on the other systems is confirmed.

Ghrelin induces adiposity in rodents

It is proposed that ghrelin, in addition to its role in regulating GH secretion, signals the hypothalamus when an increase in metabolic efficiency is necessary, suggesting an involvement in regulation of energy balance.

Ghrelin modulates the activity and synaptic input organization of midbrain dopamine neurons while promoting appetite.

It is shown that in mice and rats, ghrelin bound to neurons of the VTA, where it triggered increased dopamine neuronal activity, synapse formation, and dopamine turnover in the nucleus accumbens in a GHSR-dependent manner, suggesting that the mesolimbic reward circuitry is targeted by peripheral gh Relin to influence physiological mechanisms related to feeding.

A Role of Ghrelin in Neuroendocrine and Behavioral Responses to Stress in Mice

The findings suggest that ghrelin may have a role in mediating neuroendocrine and behavioral responses to stressors and that the stomach could play an important role, not only in the regulation of appetite, but also in theregulation of anxiety.

Role of the ghrelin system in alcoholism: Acting on the growth hormone secretagogue receptor to treat alcohol-related diseases.

These findings suggest that the ghrelin system plays a role in alcohol dependence, and suggests that GHS-R1a antagonists and/or inverse agonists might affect alcohol-seeking behavior, thus having therapeutic potential in alcohol use disorders.

Ghrelin Promotes and Protects Nigrostriatal Dopamine Function via a UCP2-Dependent Mitochondrial Mechanism

The data reveal that peripheral ghrelin plays an important role in the maintenance and protection of normal nigrostriatal dopamine function by activating UCP2-dependent mitochondrial mechanisms and the potential implications of these studies on the link between obesity and neurodegeneration.

Association of pro-ghrelin and GHS-R1A gene polymorphisms and haplotypes with heavy alcohol use and body mass.

The present findings are the first to disclose an association between the pro-ghrelin and GHS-R1A genes and heavy alcohol use, further strengthening the role of the ghrelin system in addictive behaviors and brain reward.
