Nicotinic acetylcholine receptors modulate osteoclastogenesis [PDF]

open access: yesArthritis Research & Therapy, 2016
Our aim was to investigate the role of nicotinic acetylcholine receptors (nAChRs) in in-vitro osteoclastogenesis and in in-vivo bone homeostasis.The presence of nAChR subunits as well as the in-vitro effects of nAChR agonists were investigated by ex vivo osteoclastogenesis assays, real-time polymerase chain reaction, Western blot and flow cytometry in ...

Bispyridinium Compounds Inhibit Both Muscle and Neuronal Nicotinic Acetylcholine Receptors in Human Cell Lines. [PDF]

open access: yesPLoS ONE, 2015
Standard treatment of poisoning by organophosphorus anticholinesterases uses atropine to reduce the muscarinic effects of acetylcholine accumulation and oximes to reactivate acetylcholinesterase (the effectiveness of which depends on the specific ...

Endogenous cholinergic inputs and local circuit mechanisms govern the phasic mesolimbic dopamine response to nicotine [PDF]

open access: yes, 2013
Nicotine exerts its reinforcing action by stimulating nicotinic acetylcholine receptors (nAChRs) and boosting dopamine (DA) output from the ventral tegmental area (VTA).

Neuronal Nicotinic Acetylcholine Receptor Modulators from Cone Snails

open access: yesMarine Drugs, 2018
Marine cone snails are a large family of gastropods that have evolved highly potent venoms for predation and defense. The cone snail venom has exceptional molecular diversity in neuropharmacologically active compounds, targeting a range of receptors, ion

Nicotine Addiction: Neurobiology and Mechanism

open access: yesJournal of Pharmacopuncture, 2020
Nicotine, primary component of tobaco produces craving and withdrawal effect both in humans and animals. Nicotine shows a close resemblance to other addictive drugs in molecular, neuroanatomical and pharmacological, particularly the drugs which enhances ...

Functional Stoichiometry at the Nicotinic Receptor. The Photon Cross Section for Phase 1 Corresponds to Two Bis-Q Molecules per Channel [PDF]

open access: yes, 1982
These experiments examine changes in the agonist-induced conductance that occur when the agonist-receptor complex is perturbed. Voltage-clamped Electrophorus electroplaques are exposed to the photoisomerizable agonist trans-Bis-Q A 1-µs laser flash ...

Structural model of nicotinic acetylcholine receptor isotypes bound to acetylcholine and nicotine [PDF]

open access: yesBMC Structural Biology, 2002
Nicotine is a psychoactive drug presenting a diverse array of biological activities, some positive, such as enhancement of cognitive performances, others negative, such as addiction liability. Ligands that discriminate between the different isotypes of nicotinic acetylcholine receptors (nAChRs) could present improved pharmacology and toxicity profile ...

Silent agonists for α7 nicotinic acetylcholine receptors

open access: yesPharmacological Research, 2023
We discuss models for the activation and desensitization of α7 nicotinic acetylcholine receptors (nAChRs) and the effects of efficacious type II positive allosteric modulators (PAMs) that destabilize α7 desensitized states.

Distribution of α7 Nicotinic Acetylcholine Receptor Subunit mRNA in the Developing Mouse. [PDF]

open access: yes, 2019
Homomeric α7 nicotinic acetylcholine receptors (nAChRs) are abundantly expressed in the central and peripheral nervous system (CNS and PNS, respectively), and spinal cord.

Filamented Light (FLight) Bioprinting of Mini‐Muscles with Self‐Renewal Potential

open access: yesAdvanced Materials, EarlyView.
This work presents the FLight biofabrication for engineering in vitro muscle constructs by photocrosslinking pristine collagen and fibrinogen using ruthenium. The resulting mini‐muscles retain in vivo‐like tissue organization and a Pax7⁺ cell pool.
