The Anti-Aggregative Peptide KLVFF Mimics Aβ1-40 in the Modulation of Nicotinic Receptors: Implications for Peptide-Based Therapy [PDF]
Biomedicines, 2022 In recent years, the inhibition of beta-amyloid (Aβ) aggregation has emerged as a potential strategy for Alzheimer’s disease. KLVFF, a small peptide corresponding to the aminoacidic sequence 16-20 of Aβ, reduces Aβ fibrillation dose dependently ...

α9-Containing Nicotinic Receptors in Cancer [PDF]
Frontiers in Cellular Neuroscience, 2022 Neuronal nicotinic acetylcholine receptors containing the α9 or the α9 and α10 subunits are expressed in various extra-neuronal tissues. Moreover, most cancer cells and tissues highly express α9-containing receptors, and a number of studies have shown ...

Structural interplay of anesthetics and paralytics on muscle nicotinic receptors [PDF]
Nature Communications, 2023 General anesthetics and neuromuscular blockers are used together during surgery to stabilize patients in an unconscious state. Anesthetics act mainly by potentiating inhibitory ion channels and inhibiting excitatory ion channels, with the net effect of ...

The Role of Nicotinic Receptors on Ca2+ Signaling in Bovine Chromaffin Cells [PDF]
Current Issues in Molecular BiologyChromaffin cells have been used as a physiological model to understand neurosecretion in mammals for many years. Nicotinic receptors located in the cells’ membrane are stimulated by acetylcholine, and they participate in the exocytosis of chromaffin ...

TLR2 and TLR4 Modulate Mouse Ileal Motility by the Interaction with Muscarinic and Nicotinic Receptors [PDF]
Cells, 2022 Irritable bowel syndrome (IBS) is a chronic functional bowel disorder characterized by intestinal dysmotility. Changes in intestinal microbiota (dysbiosis) can lead to alterations in neuro-muscular functions in the gut. Toll-like receptors (TLRs) 2 and 4

Erythrina mulungu alkaloids are potent inhibitors of neuronal nicotinic receptor currents in mammalian cells. [PDF]
PLoS ONE, 2013 Crude extracts and three isolated alkaloids from Erythrina mulungu plants have shown anxiolytic effects in different animal models. We investigated whether these alkaloids could affect nicotinic acetylcholine receptors and if they are selective for ...

Mechanosensitivity of nicotinic receptors [PDF]
Pflügers Archiv - European Journal of Physiology, 2012 Nicotinic acetylcholine receptors (nAChRs) are heteropentameric ligand-gated ion channels that mediate excitatory neurotransmission at the neuromuscular junction (NMJ) and other peripheral and central synapses. At the NMJ, acetylcholine receptors (AChRs) are constantly exposed to mechanical stress resulting from muscle contraction.

Nicotinic Receptors in Neurodegeneration [PDF]
Current Neuropharmacology, 2013 Many studies have focused on expanding our knowledge of the structure and diversity of peripheral and central nicotinic receptors. Nicotinic acetylcholine receptors (nAChRs) are members of the Cys-loop superfamily of pentameric ligand-gated ion channels, which include GABA (A and C), serotonin, and glycine receptors.

Nicotinic acetylcholine receptors [PDF]
British Journal of Pharmacology, 2018 This themed section of the British Journal of Pharmacology is the product of a conference that focussed on nicotinic ACh receptors (nAChRs) that was held on the Greek island of Crete from 7 to 11 May 2017. ‘Nicotinic acetylcholine receptors 2017’ was the fourth in a series of triennial international meetings that have provided a regular forum for ...
