Heterogenous Cholinergic Nicotinic Receptors in the CNS

, 1988
Multiple nicotinic binding sites are found in mammalian brain. Several nicotinic agonists and antagonists have been used to characterize the nicotinic binding sites.

TLR2 and TLR4 Modulate Mouse Ileal Motility by the Interaction with Muscarinic and Nicotinic Receptors

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

Identification of a domain which affects kinetics and antagonistic potency of clozapine at 5-HT3 receptors. [PDF]

, 2009
The widely used atypical antipsychotic clozapine is a potent competitive antagonist at 5-HT(3) receptors which may contribute to its unique psychopharmacological profile. Clozapine binds to 5-HT(3) receptors of various species.

Venomous secretions from marine snails of the Terebridae family target acetylcholine receptors [PDF]

, 2013
Venoms from cone snails (Conidae) have been extensively studied during the last decades, but those from other members of the suborder Toxoglossa, such as of Terebridae and Turridae superfamilies attracted less interest so far. Here, we report the effects

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Learning and nicotine interact to increase CREB phosphorylation at the jnk1 promoter in the hippocampus [PDF]

, 2012
Nicotine is known to enhance long-term hippocampus dependent learning and memory in both rodents and humans via its activity at nicotinic acetylcholinergic receptors (nAChRs).

Unique nicotinic responses are present in distinct subtypes of mouse medial prefrontal layer V pyramidal neurons

Scientific Reports
The neurotransmitter acetylcholine supports goal-directed cognitive functions via activation of its nicotinic and muscarinic classes of receptors within the prefrontal cortex.

New insight into the tick neuronal nicotinic acetylcholine receptors: from molecular to pharmacological studies

Ticks and Tick-Borne Diseases
ACh is known to be an excitatory neurotransmitter in the central nervous system of several arthropod species. Nicotinic acetylcholine receptors are involved in rapid neurotransmission and are the target of compounds used as acaricides.

Lynx Prototoxins: Roles of Endogenous Mammalian Neurotoxin-Like Proteins in Modulating Nicotinic Acetylcholine Receptor Function to Influence Complex Biological Processes

Frontiers in Pharmacology, 2019
The cholinergic system modulates many biological functions, due to the widespread distribution of cholinergic neuronal terminals, and the diffuse release of its neurotransmitter, acetylcholine.
