AI Article Synopsis

  • Ghrelin is a hormone produced in the stomach and brain that plays a role in stimulating growth hormone and appetite, but it's also linked to mood disorders like depression.
  • Research indicates that ghrelin can both increase and decrease symptoms of depression in animals, suggesting it has a complex role in emotional regulation.
  • Understanding how ghrelin interacts with other neurochemical systems could lead to new treatments for depression, highlighting its potential as a target for therapy.

Article Abstract

Ghrelin is a peptide released by the endocrine cells of the stomach and the neurons in the arcuate nucleus of the hypothalamus. It modulates both peripheral and central functions. Although ghrelin has emerged as a potent stimulator of growth hormone release and as an orexigenic neuropeptide, the wealth of literature suggests its involvement in the pathophysiology of affective disorders including depression. Ghrelin exhibits a dual role through the advancement and reduction of depressive behavior with nervousness in the experimental animals. It modulates depression-related signals by forming neuronal networks with various neuropeptides and classical neurotransmitter systems. The present review emphasizes the integration and signaling of ghrelin with other neuromodulatory systems concerning depressive disorders. The role of ghrelin in the regulation of neurosynaptic transmission and depressive illnesses implies that the ghrelin system modulation can yield promising antidepressive therapies.

A novel role for microtubule affinity-regulating kinases in neuropathic pain.

Br J Pharmacol

July 2024

From the school of Pharmacy, Key Laboratory of Molecular Pharmacology and Drug Evaluation (Yantai University), Ministry of Education, Collaborative Innovation Center of Advanced Drug Delivery System and Biotech Drugs in Universities of Shandong, Yantai University, Yantai, Shandong Province, China.

Article Synopsis
  • Neuropathic pain is a prevalent issue affecting many people, with limited effective treatment options; this study investigates the potential role of microtubule affinity-regulating kinases (MARK1 and MARK2) in this type of pain.
  • Researchers used a rat model of neuropathic pain and employed genetic knockdown of MARKs and a small molecule inhibitor to assess their influence on pain, cognitive function, and anxiety.
  • The findings revealed that inhibiting MARKs can reduce pain-like behaviors and improve cognitive and motor deficits, suggesting that targeting MARKs may offer a new approach for treating neuropathic pain.

Differential regulation of hippocampal transcriptome by circulating estrogen.

Estrogen (E2) modulates the synaptic structure and plasticity in the hippocampus. Previous studies showed that E2 fluctuations during various phases of the menstrual cycle produce subtle neurosynaptic changes that impact women's behavior, emotion, and cognitive functions. In this study, we explored the transcriptome of the hippocampus via RNA-seq (RNA-sequencing) between proestrus (PE) and diestrus (DE) stages in young female rats to determine the effect of E2 of PE and DE stages on hippocampal gene expression.

Excessive ethanol drinking is a major problem within the United States, causing alterations in brain plasticity and neurocognitive function. Astrocytes are glial cells that regulate neurosynaptic plasticity, modulate neurochemicals, and monitor other homeostatic roles. Astrocytes have been found to play a part in modulating excessive ethanol consumption.

Role of Munc18-1 in the biological functions and pathogenesis of neurological disorders (Review).

Mol Med Rep

March 2021

Department of Emergency, West China Second University Hospital, Sichuan University, Chengdu, Sichuan 610041, P.R. China.

The release of neurotransmitters following the fusion of synaptic vesicles and the presynaptic membrane is an important process in the transmission of neuronal information. Syntaxin-binding protein 1 (Munc18-1) is a synaptic fusion protein binding protein, which mainly regulates synaptic vesicle fusion and neurotransmitter release by interacting with soluble N-ethylmaleimide sensitive factor attachment protein receptor. In addition to affecting neurotransmitter transmission, Munc18-1 is also involved in regulating neurosynaptic plasticity, neurodevelopment and neuroendocrine cell release functions (including thyroxine and insulin release).
