Activation of endplate nicotinic acetylcholine receptors by agonists [PDF]

Biochemical Pharmacology, 2015
The interaction of a small molecule made in one cell with a large receptor made in another is the signature event of cell signaling. Understanding the structure and energy changes associated with agonist activation is important for engineering drugs, receptors and synapses.

Stromal cell‐derived factor‐1 regulates expression of vascular endothelial growth factor and osteopontin after tooth extraction

Journal of Periodontology, EarlyView.
Abstract Background The present study aimed to investigate the expression of stromal cell‐derived factor‐1 (SDF‐1) after tooth extraction in rats and its regulatory effect on the expression of osteopontin (OPN) and vascular endothelial growth factor (VEGF).

Functional expression and properties of the tick α6 homomeric nicotinic acetylcholine receptor in Xenopus laevis oocytes

Current Research in Parasitology and Vector-Borne Diseases
Recent studies have suggested that the tick Ixodes ricinus expresses nAChR subtypes which are activated by acetylcholine. Here, we investigated the potential of the Iricα6 subunit to form a functional receptor when expressed in Xenopus laevis oocytes ...

Nicotine Inhibits Clostridium difficile Toxin A-Induced Colitis but Not Ileitis in Rats

International Journal of Inflammation, 2016
Nicotine is protective in ulcerative colitis but not Crohn’s disease of the small intestine, but little is known about the effects of nicotine on Clostridium difficile toxin A-induced enteritis.

Dyskinesia and brain-derived neurotrophic factor levels after long-term levodopa and nicotinic receptor agonist treatments in female mice with near-total unilateral dopaminergic denervation

BMC Neuroscience, 2018
Background The treatment of Parkinson’s disease is often complicated by levodopa-induced dyskinesia (LID). Nicotinic acetylcholine receptor agonists can alleviate LID in animal models but may be less effective in conditions of severe dopaminergic ...

Single channel study of the spasmodic mutation α1A52S in recombinant rat glycine receptors [PDF]

, 2007
Inherited defects in glycine receptors lead to hyperekplexia, or startle disease. A mutant mouse, spasmodic, that has a startle phenotype, has a point mutation (A52S) in the glycine receptor α1 subunit.

Sympathetic Shift and Insular Alteration: Unravelling the Link Between Anxiety and Heart Rate Variability in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Anxiety and autonomic dysfunction are frequent non‐motor symptoms of Parkinson's disease (PD). Their relationship, as well as the neural mechanisms underlying this relationship, remain unexplored. Objectives We aimed to investigate the relationship between cardiovascular functions and anxiety in PD and the structural neural changes ...

Dopamine D_2-receptor activation elicits akinesia, rigidity, catalepsy, and tremor in mice expressing hypersensitive 4 nicotinic receptors via a cholinergic-dependent mechanism [PDF]

, 2010
Recent studies suggest that high-affinity neuronal nicotinic acetylcholine receptors (nAChRs) containing α4 and β2 subunits (α4β2*) functionally interact with G-protein-coupled dopamine (DA) D_2 receptors in basal ganglia.

UB-165: A Novel Nicotinic Agonist with Subtype Selectivity Implicates the α4β2* Subtype in the Modulation of Dopamine Release from Rat Striatal Synaptosomes

Journal of Neuroscience, 2000
Presynaptic nicotinic acetylcholine receptors (nAChRs) on striatal synaptosomes stimulate dopamine release. Partial inhibition by the α3β2-selective α-conotoxin-MII indicates heterogeneity of presynaptic nAChRs on dopamine terminals.
