Vagus nerve stimulation‐induced stromal cell‐derived factor‐l alpha participates in angiogenesis and repair of infarcted hearts

open access: yesESC Heart Failure, 2023
Aims We aim to explore the role and mechanism of vagus nerve stimulation (VNS) in coronary endothelial cells and angiogenesis in infarcted hearts. Methods and results Seven days after rat myocardial infarction (MI) was prepared by ligation of the left ...

Antinociception induced by stimulating amygdaloid nuclei in rats: changes produced by systemically administered antagonists

open access: yesBrazilian Journal of Medical and Biological Research, 1998
The antinociceptive effects of stimulating the medial (ME) and central (CE) nuclei of the amygdala in rats were evaluated by the changes in the latency for the tail withdrawal reflex to noxious heating of the skin.

Human Secreted Ly-6/uPAR Related Protein-1 (SLURP-1) Is a Selective Allosteric Antagonist of α7 Nicotinic Acetylcholine Receptor. [PDF]

open access: yesPLoS ONE, 2016
SLURP-1 is a secreted toxin-like Ly-6/uPAR protein found in epithelium, sensory neurons and immune cells. Point mutations in the slurp-1 gene cause the autosomal inflammation skin disease Mal de Meleda.

The Acetylcholine Esterase Inhibitor Donepezil Increases Dopamine Levels in the Nucleus Accumbens and Blocks the Alcohol Deprivation Effect in Rats

open access: yesAddiction Biology, Volume 31, Issue 4, April 2026.
This study examined the effects of donepezil on mesolimbic dopamine signalling and alcohol‐related behaviours in male rats. Donepezil increases nucleus accumbens dopamine via muscarinic mechanisms and prevented further dopamine elevation after alcohol administration. Although it did not reduce regular alcohol intake, it abolished relapse‐like drinking.

Critical roles of nicotinic acetylcholine receptors in olfactory memory formation and retrieval in crickets

open access: yesFrontiers in Physiology
Acetylcholine (ACh) is a major excitatory neurotransmitter in the insect central nervous system, and insect neurons express several types of ACh receptors (AChRs).

Acetylcholine Attenuates Hydrogen Peroxide-Induced Intracellular Calcium Dyshomeostasis Through Both Muscarinic and Nicotinic Receptors in Cardiomyocytes

open access: yesCellular Physiology and Biochemistry, 2016
Background/Aims: Oxidative stress induced intracellular Ca2+ overload plays an important role in the pathophysiology of several heart diseases. Acetylcholine (ACh) has been shown to suppress reactive oxygen species generation during oxidative stress ...

Enhanced alcohol-seeking behavior by nicotine in the posterior ventral tegmental area of female alcohol-preferring (P) rats: modulation by serotonin-3 and nicotinic cholinergic receptors [PDF]

open access: yes, 2014
RATIONALE: Alcohol and nicotine co-use can reciprocally promote self-administration and drug-craving/drug-seeking behaviors. To date, the neurocircuitry in which nicotine influences ethanol (EtOH) seeking has not been elucidated.

Mecamylamine (a nicotine antagonist) for smoking cessation [PDF]

open access: yesCochrane Database of Systematic Reviews, 1998
Mecamylamine is a nicotine antagonist (that is it blocks the effect of nicotine). The rationale for its use in smoking cessation is that it may block the rewarding effect of nicotine and thus reduce the urge to smoke.The objective of this review was to determine the effectiveness of mecamylamine in promoting smoking cessation, either alone or in ...

Sex differences in neuromodulatory subcortical systems and their implications for Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract Neuromodulatory subcortical systems (NSSs) are uniquely susceptible to dementia‐related pathology, leading to frequent molecular and behavioral impairments associated with altered function of these nuclei. Some of these systems display clear sex‐specific cytoarchitecture and signaling leading to distinct physiology and behavioral outputs in ...
