Resilient Hippocampal Gamma Rhythmogenesis and Parvalbumin-Expressing Interneuron Function Before and After Plaque Burden in 5xFAD Alzheimer’s Disease Model

open access: yesFrontiers in Synaptic Neuroscience, 2022
Recent studies have implicated impaired Parvalbumin Fast-Spiking Interneuron (PVIN) function as a precipitating factor underlying abnormalities in network synchrony, oscillatory rhythms, and cognition associated with Alzheimer’s disease (AD).

Carbachol and Nicotine in Prefrontal Cortex Have Differential Effects on Sleep-Wake States

open access: yesFrontiers in Neuroscience, 2020
The role of the brainstem cholinergic system in the regulation of sleep-wake states has been studied extensively but relatively little is known about the role of cholinergic mechanisms in prefrontal cortex in the regulation of sleep-wake states.

Muscarinic Receptors as Targets for Metronomic Therapy in Ovarian Cancer

open access: yesDüzce Tıp Fakültesi Dergisi, 2023
Aim: In this study, the effects of muscarinic acetylcholine receptor (mAChR) agonist carbachol on the proliferation of cisplatin-resistant (A2780cis) and cisplatin-free (SKOV-3) ovarian cancer cell line were for the first time investigated to further ...

Intracellular stored calcium plays a minor role in Gq-coupled receptor-mediated contraction in rat airway smooth muscle

open access: yesLife Sciences, Medicine and Biomedicine, 2018
The general notion of activation of Gq-protein coupled receptors involves the mobilisation of stored and extracellular calcium and leads to smooth muscle tissue contraction.

Clinical outcomes of combined versus separate carbachol and brimonidine drops in correcting presbyopia

open access: yesEye and Vision, 2016
BackgroundTo test and compare in a masked fashion the efficacy of using a parasympathomimetic drug (3% carbachol) and an alpha-2 agonist (0.2% brimonidine) in both combined and separate forms to create optically beneficial miosis to pharmacologically ...

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]

open access: yes, 1992
We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

Medial Septum Modulates Cellular Response Induced in Hippocampus on Microinjection of Cholinergic Agonists into Hypothalamic Lateral Supramammillary Nucleus

open access: yesFrontiers in Neuroanatomy, 2017
Cholinergic mechanisms in supramammillary nucleus (SuM), especially the lateral SuM (lSuM) modulates septo-hippocampal neural activity. The lSuM, as compared to the contiguous medial SuM (mSuM) has relatively dense projections to hippocampus and ...

The Muscarinic Acetylcholine M2 Receptor-Induced Nitration of p190A by eNOS Increases RhoA Activity in Cardiac Myocytes

open access: yesCells, 2023
p190RhoGAP, which exists in two paralogs, p190RhoGAP-A (p190A) and p190RhoGAP-B (p190B), is a GTPase activating protein (GAP) contributing to the regulation of the cellular activity of RhoGTPases.

Distinct agonist regulation of muscarinic acetylcholine M2-M3 heteromers and their corresponding homomers [PDF]

open access: yes, 2015
Each subtype of the muscarinic receptor family of G protein-coupled receptors is activated by similar concentrations of the neurotransmitter acetylcholine or closely related synthetic analogs such as carbachol. However, pharmacological selectivity can be

Multiple Residues in the Second Extracellular Loop Are Critical for M3 Muscarinic Acetylcholine Receptor Activation [PDF]

open access: yes, 2007
Recent studies suggest that the second extracellular loop (o2 loop) of bovine rhodopsin and other class I G protein-coupled receptors (GPCRs) targeted by biogenic amine ligands folds deeply into the transmembrane receptor core where the binding of cis ...
