Marks M, Loetz E, Ortiz N, Herder P, Collins A
Behav Pharmacol
. 2020 Jun;
31(7):688-701.
PMID: 32568759
The diversity of nicotinic cholinergic receptor (nAChR) subunits underlies the complex responses to nicotine. Mice differing in the expression of α4 and β2 subunits, which are most widely expressed in...

McClure-Begley T, Grady S, Marks M, Collins A, Stitzel J
Biochem Pharmacol
. 2014 Jun;
91(1):87-96.
PMID: 24953818
Activation of nicotinic acetylcholine receptors (nAChRs) can elicit neurotransmitter release from presynaptic nerve terminals. Mechanisms contributing to cell-and-terminal specific regulation of nAChR-mediated neurotransmitter exocytosis are not fully understood. The experiments...

J Addict Res Ther
. 2012 Dec;
S2.
PMID: 23264883
Nicotine addiction is a complex process that begins with self-administration. Consequently, this process has been studied extensively using animal models. A person is usually not called "smoker" if s/he has...

Zambrano C, Salamander R, Collins A, Grady S, Marks M
J Pharmacol Exp Ther
. 2012 Apr;
342(2):245-54.
PMID: 22532626
Chronic nicotine produces up-regulation of α4β2* nicotinic acetylcholine receptors (nAChRs) (* denotes that an additional subunit may be part of the receptor). However, the extent of up-regulation to persistent ligand...

McClure-Begley T, Wageman C, Grady S, Marks M, McIntosh J, Collins A, et al.
J Neurochem
. 2012 Apr;
122(1):48-57.
PMID: 22506481
Mouse superficial superior colliculus (SuSC) contains dense GABAergic innervation and diverse nicotinic acetylcholine receptor subtypes. Pharmacological and genetic approaches were used to investigate the subunit compositions of nicotinic acetylcholine receptors...

Neuropharmacology
. 2011 Apr;
61(1-2):189-201.
PMID: 21504750
To study individual differences in nicotine preference and intake, male and female rats were given free access to a choice of oral nicotine (10 or 20 mg/L) or water for...

Marks M, McClure-Begley T, Whiteaker P, Salminen O, Brown R, Cooper J, et al.
J Pharmacol Exp Ther
. 2011 Jan;
337(1):187-200.
PMID: 21228066
Chronic nicotine treatment elicits a brain region-selective increase in the number of high-affinity agonist binding sites, a phenomenon termed up-regulation. Nicotine-induced up-regulation of α4β2-nicotinic acetylcholine receptors (nAChRs) in cell cultures...

Marks M, Meinerz N, Brown R, Collins A
Biochem Pharmacol
. 2010 Jul;
80(8):1238-51.
PMID: 20599770
The nicotinic acetylcholine receptors (nAChR) assembled from alpha4 and beta2 subunits are the most densely expressed subtype in the brain. Concentration-effect curves for agonist activation of alpha4beta2*-nAChR are biphasic. This...

J Mol Neurosci
. 2009 Aug;
40(1-2):91-5.
PMID: 19693710
Wild-type and alpha5 null mutant mice were used to identify nicotinic cholinergic receptors (nAChRs) that mediate alpha-conotoxin MII (alpha-CtxMII)-resistant dopamine (DA) release from striatal synaptosomes. Concentration-effect curves for ACh-stimulated release...

J Mol Neurosci
. 2009 Aug;
40(1-2):96-104.
PMID: 19672723
The diversity of nicotinic acetylcholine receptor (nAChR) subtypes was explored by measuring the effects of gene deletion and pharmacological diversity of epibatidine binding sites in mouse brain. All epibatidine binding...
