Effects of Corticotrophin Releasing Factor, Muscarine and Somatostatin on Rubidium and Potassium Efflux from Mouse AtT-20 Pituitary Cells.

The European journal of neuroscience

Luini A, Brown DA.
PMID: 12106055
Eur J Neurosci. 1990 Feb;2(2):126-131. doi: 10.1111/j.1460-9568.1990.tb00404.x.

Effects of secretagogues and anti-secretagogues of ACTH secretion on K+ permeability in the clonal pituitary cell line AtT-20 were measured by recording 86Rb or 42K efflux. Efflux was accelerated by the secretagogues K+, corticotrophin, forskolin, isoprenaline, and the Ca-ionophore...

Muscarinic receptors coupled to inositol phospholipid breakdown in human SH-SY5Y neuroblastoma cells: Effect of retinoic acid-induced differentiation.

Neurochemistry international

Fowler CJ, O'Neill C, Almqvist P, Nilsson S, Wiehager B, Winblad B.
PMID: 20504467
Neurochem Int. 1989;15(1):73-9. doi: 10.1016/0197-0186(89)90078-8.

In human SH-SY5Y neuroblastoma cells, carbachol stimulates inositol phospholipid breakdown with an EC(50) value of 18 ?M. The response is prevented by pirenzepine, with a Hill coefficient of 0.57 and an IC(50) value of 0.15 ?M. A Gpp[NH]p-stimulated [(3)H]phosphatidylinositol-4,5-bisphosphate...

Beta Amyloid Differently Modulate Nicotinic and Muscarinic Receptor Subtypes which Stimulate in vitro and in vivo the Release of Glycine in the Rat Hippocampus.

Frontiers in pharmacology

Zappettini S, Grilli M, Olivero G, Mura E, Preda S, Govoni S, Salamone A, Marchi M.
PMID: 22866037
Front Pharmacol. 2012 Jul 27;3:146. doi: 10.3389/fphar.2012.00146. eCollection 2012.

Using both in vitro (hippocampal synaptosomes in superfusion) and in vivo (microdialysis) approaches we investigated whether and to what extent β amyloid peptide 1-40 (Aβ 1-40) interferes with the cholinergic modulation of the release of glycine (GLY) in the...

Role of prediction error and the cholinergic system on memory reconsolidation processes in mice.

Neurobiology of learning and memory

Krawczyk MC, Millan J, Blake MG, Boccia MM.
PMID: 34619364
Neurobiol Learn Mem. 2021 Nov;185:107534. doi: 10.1016/j.nlm.2021.107534. Epub 2021 Oct 04.

The ability to make predictions based on stored information is a general coding strategy. A prediction error (PE) is a mismatch between expected and current events. Our memories, like ourselves, are subject to change. Thus, an acquired memory can...

MOTOR NEURONES OF THE CRAYFISH WALKING SYSTEM POSSESS TEA+-REVEALED REGENERATIVE ELECTRICAL PROPERTIES.

The Journal of experimental biology

Cattaert D, Araque A, Buno W, Clarac F.
PMID: 9317925
J Exp Biol. 1994 Mar;188(1):339-45.

In crustaceans, some motor neurones (MNs) have been shown to be part of the central pattern generator in the stomatogastric system (Harris-Warrick et al. 1992; Moulins, 1990), the swimmeret system (Heitler, 1978) or the walking system (Chrachri and Clarac,...

Effects of nicotinic and muscarinic ligands on embryonic neurones of Periplaneta americana in primary culture: a whole cell clamp study.

Journal of insect physiology

Pichon Y, Guillet JC, Le Guen J, Tiaho F, Van Eyseren I.
PMID: 12769957
J Insect Physiol. 1998 Mar;44(3):227-240. doi: 10.1016/s0022-1910(97)00165-0.

The pharmacological properties of acetylcholine (ACh) receptors of cultured neurones from embryonic cockroach brains were studied using the whole-cell configuration of the patch-clamp technique. More than 90% of the studied neurones responded to ACh by a monophasic inward current,...

Effects of nicotine, oxotremorine and 9-amino 1,2,3,4- tetrahydroacridine (tacrine) on matching and non matching to position in rats: no evidence for mnemonic enhancement.

Journal of psychopharmacology (Oxford, England)

Sahgal A, Keith AB, Lloyd S.
PMID: 22281850
J Psychopharmacol. 1990 Jan;4(4):210-8. doi: 10.1177/026988119000400405.

Groups of rats were trained on one of two variants of an operant memory task which allows strength of memory (accuracy), bias and response rates to be measured directly. In matching to position (MTP), one of two retractable response...

Effects of muscarinic receptor agonists and antagonists on swim-stress-induced 'behavioural despair' in rats.

Journal of psychopharmacology (Oxford, England)

Bhattacharya SK, Sen AP.
PMID: 22282123
J Psychopharmacol. 1991 Jan;5(1):77-81. doi: 10.1177/026988119100500111.

The effects of some selective agonists and antagonists of cholinergic muscarinic receptor subtypes on swim-stress-induced immobility (SI) was investigated in rats. This paradigm has been proposed to assess 'behavioural despair' in rodents as a laboratory model for clinical depression....

Variability in the Drug Response of M.

Frontiers in pharmacology

Valuskova P, Riljak V, Forczek ST, Farar V, Myslivecek J.

Front Pharmacol. 2019 Mar 18;10:237. doi: 10.3389/fphar.2019.00237. eCollection 2019.

Mice are nocturnal animals. Surprisingly, the majority of physiological/pharmacological studies are performed in the morning, i.e., in the non-active phase of their diurnal cycle. We have shown recently that female (not male) mice lacking the M

Glucocorticoid-cholinergic interactions in the dorsal striatum in memory consolidation of inhibitory avoidance training.

Front Behav Neurosci. 2012 Jun 22;6:33. doi: 10.3389/fnbeh.2012.00033. eCollection 2012.

Extensive evidence indicates that glucocorticoid hormones act in a variety of brain regions to enhance the consolidation of memory of emotionally motivated training experiences. We previously reported that corticosterone, the major glucocorticoid in the rat, administered into the dorsal...

Different times of development of tremor to harmaline and oxotremorine in neonatal rats.
