Addiction, EarlyView.Abstract Background and aims Tobacco smoking is a major risk factor for cardiovascular and lung diseases. A better understanding of its neurobiological underpinnings will benefit the prevention of smoking‐related illnesses and mortality. Previous studies link smoking to increased iron concentration in the striatum, a central component of the brain's ...

Cholinergic Modulation of Locomotion and Striatal Dopamine Release Is Mediated by α6α4* Nicotinic Acetylcholine Receptors [PDF]
, 2010 Dopamine (DA) release in striatum is governed by firing rates of midbrain DA neurons, striatal cholinergic tone, and nicotinic ACh receptors (nAChRs) on DA presynaptic terminals.

A Cation-π Interaction in the Binding Site of the Glycine Receptor Is Mediated by a Phenylalanine Residue [PDF]
, 2008 Cys-loop receptor binding sites characteristically contain many aromatic amino acids. In nicotinic ACh and 5-HT3 receptors, a Trp residue forms a cation-{pi} interaction with the agonist, whereas in GABAA receptors, a Tyr performs this role.

Addiction, EarlyView.Abstract Background and aims By assessing neuroaffective response to motivationally relevant cues before a quit attempt, we have shown that smokers who attribute greater incentive salience to cigarette‐related cues than non‐cigarette‐related rewards (Sign‐trackers, ST) benefit more from varenicline compared with smokers with the opposite neuroaffective

Agrin-induced acetylcholine receptor clustering in mammalian muscle requires tyrosine phosphorylation. [PDF]
, 1996 Agrin is thought to be the nerve-derived factor that initiates acetylcholine receptor (AChR) clustering at the developing neuromuscularjunction. We have investigated the signaling pathway in mouse C2 myotubes and report that agrin induces a rapid but ...

Addiction, EarlyView.Abstract Background and aims Cannabis is the most widely used illicit drug worldwide and is often co‐used with tobacco, the leading cause of preventable death. Although cannabis and tobacco have distinct neurobiological actions, their associations with brain volumes are unclear.

Structure of nicotinic acetylcholine receptors
Current Opinion in Neurobiology, 1993 Nicotinic acetylcholine (ACh) receptors convert the binding of ACh into the opening of a cation-conducting channel. New information about the regions of the receptor most immediately involved in its function, namely the ACh-binding sites, the gate and the channel, has come from two approaches.

Acetylcholine induces stem cell properties of gastric cancer cells of diffuse type
Tumor Biology, 2018 Gastric cancer is the third leading cause of cancer-related death worldwide, but the mechanisms of gastric carcinogenesis are not completely understood.
