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).

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...

Unexpected loss of sensitivity to the nicotinic acetylcholine receptor antagonist activity of mecamylamine and dihydro‐β‐erythroidine in nicotine‐tolerant mice

Brain and Behavior, 2020
Objectives There is a long‐standing interest in developing nicotinic acetylcholine receptor (nAChR) antagonists for concomitant use with nAChR agonists (e.g., nicotine replacement) as complementary smoking cessation aids.

Effects of nicotine metabolites on nicotine withdrawal behaviors in mice

, 2017
Introduction: Rodent studies suggest that nicotine metabolites and minor tobacco alkaloids such as nornicotine and cotinine may promote cigarette smoking by enhancing nicotine rewarding and reinforcing effects. However, there is little information on the

Reframing the Gut–Brain Axis: The Gut Wall as a Neural Immune Interface in Multiple Sclerosis and Autoimmune Neurological Diseases

Annals of Neurology, EarlyView.
Gut wall physiology in multiple sclerosis (MS) and autoimmune neurologic diseases remains underexplored but may span gut barrier dysfunction, enteric glial targeting, mucosal immune dysregulation, and autoimmune targets within the enteric nervous system (ENS).

CYP2A6 Polymorphisms May Strengthen Individualized Treatment for Nicotine Dependence

Scientifica, 2015
Each CYP2A6 gene variant metabolizes nicotine differently depending on its enzymatic activities. The normal nicotine metabolizer CYP2A6*1A is associated with high scores of nicotine dependence (5–10) on the Fagerström Test for Nicotine Dependence (FTND ...
