Neonicotinoids disrupt memory, circadian behaviour and sleep

open access: yesScientific Reports, 2021
Globally, neonicotinoids are the most used insecticides, despite their well-documented sub-lethal effects on beneficial insects. Neonicotinoids are nicotinic acetylcholine receptor agonists.

Advances in small molecule selective ligands for heteromeric nicotinic acetylcholine receptors

open access: yesPharmacological Research, 2023
The study of nicotinic acetylcholine receptors (nAChRs) has significantly progressed in the last decade, due to a) the improved techniques available for structural studies; b) the identification of ligands interacting at orthosteric and allosteric ...

Alpha9 nicotinic acetylcholine receptors and the treatment of pain [PDF]

open access: yes, 2009
Chronic pain is a vexing worldwide problem that causes substantial disability and consumes significant medical resources. Although there are numerous analgesic medications, these work through a small set of molecular mechanisms.

Expression and function of nicotinic acetylcholine receptors in stem cells

open access: yesAIMS Bioengineering, 2016
Nicotinic acetylcholine receptors are prototypical ligand gated ion channels typically found in muscular and neuronal tissues. Functional nicotinic acetylcholine receptors, however, have also recently been identified on other cell types, including stem ...

Regions of beta 2 and beta 4 responsible for differences between the steady state dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 neuronal nicotinic receptors [PDF]

open access: yes, 1995
We constructed chimeras of the rat beta 2 and beta 4 neuronal nicotinic subunits to locate the regions that contribute to differences between the acetylcholine (ACh) dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 receptors ...

A intrigante bioquímica da niacina: uma revisão crítica

open access: yesQuímica Nova, 2011
Niacin (nicotinamide, nicotinic acid) interferes on homeostasis, DNA regulation, signaling and longevity. Nicotinic acid reduces synthesis of lipoproteins-apo-B and increases HDL.

Letters to the editor: Nicotinic acetylcholine receptor ligands as potential targets for managing neuropathic pain induced by diabetic peripheral neuropathy

open access: yeseNeurologicalSci, 2022
Diabetic peripheral neuropathy (DPN) is a medical condition that is progressively becoming more prevalent. The underlying cause of DPN is still unknown, although there have been several hypothesized mechanisms. There are current pharmaceutical treatments

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 ...

Cholinergic suppression: A postsynaptic mechanism of long-term associative learning [PDF]

open access: yes, 1986
Food avoidance learning in the mollusc Pleurobranchaea entails reduction in the responsiveness of key brain interneurons in the feeding neural circuitry, the paracerebral feeding command interneurons (PCNs), to the neurotransmitter acetylcholine (AcCho).

Nicotinic Receptor Activity Alters Synaptic Plasticity

open access: yesThe Scientific World Journal, 2001
Studies using specific agonists, antagonists, and lesions have shown that nicotinic cholinergic systems participate in attention, learning, and memory[1,2].
