Dendritic spine density of prefrontal layer 6 pyramidal neurons in relation to apical dendrite sculpting by nicotinic acetylcholine receptors

Frontiers in Cellular Neuroscience, 2015
Prefrontal layer 6 (L6) pyramidal neurons play an important role in the adult control of attention, facilitated by their strong activation by nicotinic acetylcholine receptors.

Nicotinic Cholinergic Receptors in VTA Glutamate Neurons Modulate Excitatory Transmission

Cell Reports, 2018
Summary: Ventral tegmental area (VTA) glutamate neurons are important components of reward circuitry, but whether they are subject to cholinergic modulation is unknown.

Variations in “Functional Site” Residues and Classification of Three-Finger Neurotoxins in Snake Venoms

Toxins
Three-finger toxins (3FTxs) are the largest group of nonenzymatic toxins found in snake venoms. Among them, neurotoxins that target nicotinic acetylcholine receptors are the most well-studied ligands.

Mechanisms of Chronic Nicotine Treatment–Induced Enhancement of the Sensitivity of Cortical Neurons to the Neuroprotective Effect of Donepezil in Cortical Neurons

Journal of Pharmacological Sciences, 2010
We have previously shown that chronic donepezil treatment induces nicotinic acetylcholine receptor up-regulation and enhances the sensitivity of the neurons to the neuroprotective effect of donepezil. Further analyses revealed that the nicotinic receptor

Basic and Clinical Aspects of Non-neuronal Acetylcholine: Expression of Non-neuronal Acetylcholine in Lung Cancer Provides a New Target for Cancer

Journal of Pharmacological Sciences, 2008
Lung cancer is the leading cause of cancer death worldwide and new treatment strategies are clearly needed. The recent discovery that lung and other cancers synthesize and secrete acetylcholine (ACh) which acts as an autocrine growth factor suggests that

Cell-surface translational dynamics of nicotinic acetylcholine receptors

Frontiers in Synaptic Neuroscience, 2014
Synapse efficacy heavily relies on the number of neurotransmitter receptors available at a given time. In addition to the equilibrium between the biosynthetic production, exocytic delivery and recycling of receptors on the one hand, and the endocytic ...

Nicotinic acetylcholine receptors mediate lung cancer growth

Frontiers in Physiology, 2013
Ion channels modulate ion flux across cell membranes, activate signal transduction pathways, and influence cellular transport – vital biological functions that are inexorably linked to cellular processes that go awry during carcinogenesis.

Nicotinic Receptor Activity Alters Synaptic Plasticity

The 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].

Severe drug-induced repetitive behaviors and striatal overexpression of VAChT in ChAT-ChR2-EYFP BAC transgenic mice

Frontiers in Neural Circuits, 2014
In drug users, drug-related cues alone can induce dopamine release in the dorsal striatum. Instructive cues activate inputs to the striatum from both dopaminergic and cholinergic neurons, which are thought to work together to support motor learning and ...
