Evaluation of structurally diverse neuronal nicotinic receptor ligands for selectivity at the α6 subtype (2009)

Breining, Scott R., Bencherif, Merouane, Grady, Sharon R., Whiteaker, Paul, Marks, Michael J., Wageman, Charles R., ...

Direct comparison of pyridine versus pyrimidine substituents on a small but diverse set of ligands indicates that the pyrimidine substitution has the potential to enhance affinity and/or functional...

In vivo activation of midbrain dopamine neurons via sensitized, high-affinity α6*nicotinic acetylcholine receptors (2008)

Drenan, Ryan M., Grady, Sharon R., Whiteaker, Paul, McClure-Begley, Tristan, McKinney, Sheri, Miwa, Julie M., ...

α6-containing (α6*) nicotinic ACh receptors (nAChRs) are selectively expressed in dopamine (DA) neurons and participate in cholinergic transmission. We generated and studied mice with...

Nicotine-induced dystonic arousal complex in a mouse line harboring a human autosomal-dominant nocturnal frontal lobe epilepsy mutation (2007)

Whyte, Douglas, Cahir, Elizabeth, Lester, Henry A, Grady, Sharon R, Marks, Michael J, ...

We generated a mouse line harboring an autosomal-dominant nocturnal frontal lobe epilepsy (ADNFLE) mutation: the alpha 4 nicotinic receptor S248F knock-in strain. In this mouse, modest nicotine doses...

Pharmacological and Null Mutation Approaches Reveal Nicotinic Receptor Diversity (2000)

Paul Whiteaker, Michael J. Marks, Sharon R. Grady, Ying Lu, Marina R. Picciotto, Jean-Pierre Changeux, ...

w 125 x Z.w 3 x We have developed an array of assays for nicotinic acetylcholine receptor binding and function. I a-Bungarotoxin-, y - H nico- w 3 x tine-, and H epibatidine-binding nicotinic...

Two Pharmacologically Distinct Components of Nicotinic Receptor-Mediated Rubidium Efflux in Mouse Brain Require the (1999)

Subunit Michael Marks, Michael J. Marks, Paul Whiteaker, Jennifer Calcaterra, Jerry A. Stitzel, Amy E. Bullock, ...

Nicotinic agonist-stimulated efflux of 86 Rb 1 from mouse brain synaptosomes was monitored continuously by on-line radioactivity detection. The concentration-effect curve following a 5-s stimulation...

Pharmacological Characterization of Nicotinic Receptorstimulated GABA Release From Mouse Brain Synaptosomes (1998)

Ying Lu, Sharon Grady, Michael J. Marks, Marina Picciotto, Jean-Pierre Changeux, Allan C. Collins

Several recent electrophysiological studies have demonstrated that nicotinic agonists stimulate the release of #-aminobutyric acid (GABA) from rodent brain tissue. Our studies used a neurochemical...

Measures of viability in isolated cells (1975)

Medzihradsky, Fedor, Marks, Michael J.

Various methods were compared for estimation of cell viability. Cell count, uptake of trypan blue, release of cellular LDH, as well as cell contents of K+ and Na+ were determined in leukocytes,...

Drug inhibitable ecto-ATPase in leukocytes (1975)

Medzihradsky, Fedor, Lin, Hsia-Lien, Marks, Michael J.

In rat leukocytes, the total ATP-hydrolyzing activity was highest when determined in cells with an intact plasma membrane. The ecto-ATPase, exhibiting a Km for ATP of 0.3 mM, was inhibited 30% by...

Transport and interaction of drugs in leukocytes (1974)

Marks, Michael J., Medzihradsky, Fedor

The accumulation of selected CNS drugs by rat leukocytes was previously reported. This paper presents evidence for the transport into leukocytes of additional drugs. Also studied was the inhibition...

A simple procedure for the separation of viable blood cells, suitable for long-term in vitro experiments (1974)

Medzihradsky, Fedor, Marks, Michael J., Metcalfe, Joan I.

A simple procedure is presented for the isolation of erythrocytes, leukocytes and platelets from single small samples of both human and rat blood. The separation of cells is based on sedimentation...

Energy-dependent uptake of benzomorphans by leukocytes (1972)

Medzihradsky, Fedor, Marks, Michael J.

Pentazocine rapidly enters the brain after i.p. administration to rats. Using leukocytes as model mammalian cells, the uptake of this drug was studied. Morphologically intact and metabolically active...

Identification of a novel nicotinic binding site in mouse brain using [125I]-epibatidine

Whiteaker, Paul, Jimenez, Melissa, McIntosh, J Michael, Collins, Allan C, Marks, Michael J

[125I]-Epibatidine binds to multiple nicotinic acetylcholine receptor (nAChR) subtypes with high affinity. In this study, [125I]-epibatidine was used to label and characterize a novel nAChR subtype...
