Suppression of methamphetamine-seeking behavior by nicotinic agonists [PDF]

Proceedings of the National Academy of Sciences, 2006
To understand the mechanism of methamphetamine (MAP) craving from the viewpoint of nicotinic acetylcholinergic transmission, we examined the responsible site of the brain for anticraving effects produced by nicotinic agonists by using a MAP self-administration paradigm in rats.

Paternal Exposure to the Neonicotinoid Pesticide Clothianidin Alters Sperm MicroRNA Profiles in Mice and Intergenerationally Reduces Locomotor Activity in Male Offspring

Journal of Applied Toxicology, EarlyView.
ABSTRACT Accumulating evidence suggests that paternal environmental factors have epigenetic effects on sperm and influence offspring. Neonicotinoid pesticides (NNs), which are widely used around the world, are known to affect offspring phenotypes through maternal exposure in mice, but the effect of the paternal exposure remains unknown.

Expression of the α7 nicotinic acetylcholine receptor in human lung cells

Respiratory Research, 2005
Background We and others have shown that one of the mechanisms of growth regulation of small cell lung cancer cell lines and cultured pulmonary neuroendocrine cells is by the binding of agonists to the α7 neuronal nicotinic acetylcholine receptor.

From ab initio quantum mechanics to molecular neurobiology: A cation-pi binding site in the nicotinic receptor [PDF]

, 1998
The nicotinic acetylcholine receptor is the prototype ligand-gated ion channel. A number of aromatic amino acids have been identified as contributing to the agonist binding site, suggesting that cation-pi interactions may be involved in binding the ...

Caenorhabditis elegans muscle Cys-loop receptors as novel targets of terpenoids with potential anthelmintic activity [PDF]

, 2019
The anthelmintic treatment of nematode infections remains the pillar of worm control in both human and veterinary medicine. Since control is threatened by the appearance of drug resistant nematodes, there is a need to develop novel compounds, among which

Nicotinic Acid Receptor Agonists Differentially Activate Downstream Effectors [PDF]

Journal of Biological Chemistry, 2007
Nicotinic acid remains the most effective therapeutic agent for the treatment and prevention of atherosclerosis resulting from low high density lipoprotein cholesterol. The therapeutic actions of nicotinic acid are mediated by GPR109A, a Gi protein-coupled receptor, expressed primarily on adipocytes, Langerhans cells, and macrophage.

Ivermectin Toxicity in Humans and Animals: Clinical Spectrum, Mechanisms, and Management

Journal of Applied Toxicology, EarlyView.
ABSTRACT Ivermectin is a widely used macrocyclic lactone with established efficacy against a broad range of parasitic infections in humans and animals and a long‐standing reputation for clinical safety. However, increasing evidence indicates that ivermectin can produce clinically relevant toxicity under specific conditions, particularly involving the ...

Activation of α7 nicotinic acetylcholine receptor by nicotine selectively up-regulates cyclooxygenase-2 and prostaglandin E₂ in rat microglial cultures

Journal of Neuroinflammation, 2005
Background Nicotinic acetylcholine (Ach) receptors are ligand-gated pentameric ion channels whose main function is to transmit signals for the neurotransmitter Ach in peripheral and central nervous system.

Energetic contributions to channel gating of residues in the muscle nicotinic receptor β1 subunit. [PDF]

PLoS ONE, 2013
In the pentameric ligand-gated ion channel family, transmitter binds in the extracellular domain and conformational changes result in channel opening in the transmembrane domain.

Neurotensin Agonist Attenuates Nicotine Potentiation to Cocaine Sensitization [PDF]

Behavioral Sciences, 2014
Tobacco usage typically precedes illicit drug use in adolescent and young adult populations. Several animal studies suggest nicotine increases the risk for subsequent cocaine abuse, and may be a negative prognostic factor for treatment of cocaine addiction; i.e., a “gateway drug”. Neurotensin (NT) is a 13-amino acid neuropeptide that modulates dopamine,
