Tetrahydrobiopterin analogues with NO-dependent pulmonary vasodilator properties [PDF]

open access: yes, 2011
Reduced NO levels due to the deficiency of tetrahydrobiopterin (BH4) contribute to impaired vasodilation in pulmonary hypertension Due to the chemically unstable nature of BH4 it was hypothesised that oxidatively stable analogues of BR, would be able to ...

In vitro Comparison of the Intrinsic Activity of Functional Antagonism between β-agonists and Spasmogens in the Guinea-pig Tracheal Muscle

open access: yesAllergology International, 2005
Background: The bronchodilating action of β-agonists depends on the tone of airway smooth muscle or on spasmogen. To estimate the precise intrinsic activity of β-agonists, relaxation responses should be examined on maximally contracted airway smooth ...

Recovery of hippocampal functions and modulation of muscarinic response by electroacupuncture in young diabetic rats [PDF]

open access: yes, 2017
The muscarinic receptor response to acetylcholine regulates the hippocampal-related learning, memory, neural plasticity and the production and processing of the pro-nerve growth factor (proNGF) by hippocampal cells.

Regulation of CCK-induced ERK1/2 activation by PKC epsilon in rat pancreatic acinar cells

open access: yesAIMS Molecular Science, 2017
The extracellular signal-regulated kinase ERK1/2 is activated in pancreatic acinar cells by cholecystokinin (CCK) and other secretagogues with this activation mediated primarily by protein kinase C (PKC).

From Synaptic Plasticity and Critical Periods to Social Behavior and Stress: Getting to, and Staying in, CA2. [PDF]

open access: yesHippocampus
ABSTRACT Hippocampal Area CA2, with some exceptions, had long been neglected in in vivo studies, due largely to its small size, and in in vitro studies because of its general similarity to CA3 and CA1. Increasing evidence showing that CA2 was molecularly distinct led to the increased appreciation of CA2 as a separate region, and as such, that it likely

Carbachol regulates pacemaker activities in cultured interstitial cells of Cajal from the mouse small intestine

open access: yesMolecules and Cells, 2009
We studied the effect of carbachol on pacemaker currents in cultured interstitial cells of Cajal (ICC) from the mouse small intestine by muscarinic stimulation using a whole cell patch clamp technique and Ca2+-imaging.

Intracellular free sodium and potassium, post-carbachol hyperpolarization, and extracellular potassium-undershoot in rat sympathetic neurones [PDF]

open access: yes, 1983
Double-barrelled ion-sensitive microelectrodes were used to record the free intracellular Na+- and K+-concentrations ([Na+]i, [K+]i) and to determine their relation to changes in membrane potential and extracellular K+ ([K+]e) in rat sympathetic ganglia.

Autoantibodies against muscarinic receptors in breast cancer: their role in tumor angiogenesis. [PDF]

open access: yesPLoS ONE, 2013
The presence of autoantibodies in cancer has become relevant in recent years. We demonstrated that autoantibodies purified from the sera of breast cancer patients activate muscarinic acetylcholine receptors in tumor cells.

Carbachol stimulates transactivation of epidermal growth factor receptor and mitogen-activated protein kinase in T84 cells. Implications for carbachol-stimulated chloride secretion.

open access: yesJournal of Biological Chemistry, 1998
We have examined the role of tyrosine phosphorylation in regulation of calcium-dependent chloride secretion across T84 colonic epithelial cells. The calcium-mediated agonist carbachol (CCh, 100 microM) stimulated a time-dependent increase in tyrosine ...

The Transition Between Slow-Wave Sleep and REM Sleep Constitutes an Independent Sleep Stage Organized by Cholinergic Mechanisms in the Rostrodorsal Pontine Tegmentum

open access: yesFrontiers in Neuroscience, 2019
There is little information on either the transition state occurring between slow-wave sleep (SWS) and rapid eye movement (REM) sleep, as well as about its neurobiological bases.
