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,

Developmental synaptic changes at the transient olivocochlear-inner hair cell synapse [PDF]

, 2019
In the mature mammalian cochlea, inner hair cells (IHCs) are mainly innervated by afferent fibers that convey sound information to the CNS. During postnatal development, however, medial olivocochlear (MOC) efferent fibers transiently innervate the IHCs ...

An original potentiating mechanism revealed by the cryo-EM structures of the human α7 nicotinic receptor in complex with nanobodies

Nature Communications, 2023
The human α7 nicotinic receptor is a pentameric channel mediating cellular and neuronal communication. It has attracted considerable interest in designing ligands for the treatment of neurological and psychiatric disorders. To develop a novel class of α7

Defining Nicotinic Agonist Binding Surfaces through Photoaffinity Labeling [PDF]

Biochemistry, 2007
Nicotinic acetylcholine (ACh) receptor (nAChR) agonists are potential therapeutic agents for neurological dysfunction. In the present study, the homopentameric mollusk ACh binding protein (AChBP), used as a surrogate for the extracellular ligand-binding domain of the nAChR, was specifically derivatized by the highly potent agonist azidoepibatidine ...

Efficacy of combined varenicline and nicotine replacement therapy compared with varenicline or nicotine replacement therapy alone for smoking cessation: A systematic review and meta‐analysis

Addiction, EarlyView.
Abstract Aims To assess whether combining nicotine replacement therapy (NRT) with varenicline improves long‐term smoking cessation rates compared with varenicline or NRT alone. Method Systematic review and meta‐analysis of randomized controlled trials (RCTs) or quasi‐RCTs, conducted according to PRISMA guidelines.

A fluorophore attached to nicotinic acetylcholine receptor beta M2 detects productive binding of agonist to the alpha delta site [PDF]

, 2004
To study conformational transitions at the muscle nicotinic acetylcholine (ACh) receptor (nAChR), a rhodamine fluorophore was tethered to a Cys side chain introduced at the beta-19' position in the M2 region of the nAChR expressed in Xenopus oocytes ...

Single-channel behavior of heteromeric α1β glycine receptors: an attempt to detect a conformational change before the channel opens [PDF]

, 2004
The α1β heteromeric receptors are likely to be the predominant synaptic form of glycine receptors in the adult. Their activation mechanism was investigated by fitting putative mechanisms to single-channel recordings obtained at four glycine ...

High Throughput Random Mutagenesis and Single Molecule Real Time Sequencing of the Muscle Nicotinic Acetylcholine Receptor. [PDF]

PLoS ONE, 2016
High throughput random mutagenesis is a powerful tool to identify which residues are important for the function of a protein, and gain insight into its structure-function relation.
