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

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).

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

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.

Nicotinic receptors as targets for novel analgesics and anti-infl ammatory drugs

, 2014
Nicotine and nicotinic receptors have been explored for the past three decades as a strategy for pain control. These receptors are widely expressed throughout the central and peripheral nervous system as well as immune cells.

Distinct pharmacological and functional properties of NMDA receptors in mouse cortical astrocytes [PDF]

, 2011
Background and purpose Astrocytes of the mouse neocortex express functional NMDA receptors which are not blocked by Mg2+ions. However, study of the pharmacological profile of glial NMDARs and their subunit composition is far from complete ...

[18F]Fluorodeprenyl‐D2 PET as a Tool to Monitor Disease Activity in GAD65‐Ab Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate [18F]fluorodeprenyl‐D2 ([18F]F‐DED) positron‐emission tomography (PET) imaging as a biomarker of disease activity in autoimmune encephalitis (AIE) associated with glutamic acid decarboxylase 65 (GAD65) antibodies. Methods [18F]F‐DED PET was performed in 25 GAD65‐AIE patients and 8 controls using dynamic (0–60 min) and ...

Changes in conformation and subcellular distribution of alpha(4)beta(2) nicotinic acetylcholine receptors revealed by chronic nicotine treatment and expression of subunit chimeras [PDF]

, 2002
Chronic exposure to nicotine, as occurs during tobacco smoking, is one of several factors that have been reported to cause an upregulation of neuronal nicotinic acetylcholine receptors (nAChRs).
