Macrophage TNF-α mediates parathion-induced airway hyperreactivity in guinea pigs. [PDF]

open access: yes, 2013
Organophosphorus pesticides (OPs) are implicated in human asthma. We previously demonstrated that, at concentrations that do not inhibit acetylcholinesterase activity, the OP parathion causes airway hyperreactivity in guinea pigs as a result of ...

Structural determinants at the M2 muscarinic receptor modulate the RGS4-GIRK response to pilocarpine by impairment of the receptor voltage sensitivity. [PDF]

open access: yes, 2017
Membrane potential controls the response of the M2 muscarinic receptor to its ligands. Membrane hyperpolarization increases response to the full agonist acetylcholine (ACh) while decreasing response to the partial agonist pilocarpine.

SPLICEIT Fluorescent Sensor for Integrating Dopamine Release with Cellular Resolution

open access: yesAngewandte Chemie, EarlyView.
“Single‐chain protein‐based ligand indication through a chimerically‐engineered integrator tool” (SPLICEIT) is a G‐protein coupled receptor‐based sensor design that leaves a permanent fluorescent mark. We show dopamine detection in primary cultured neurons with a fourfold signal increase normalized to an mCherry (mCh) marker.

Distribution of Muscarinic Acethylcholine Receptors and Related Signal [PDF]

open access: yesTürk Biyokimya Dergisi, 2006
Muscarinic receptors are members of G protein coupled receptor family. Molecularcloning studies indicate five intronless genes that encode five muscarinic receptorglycoproteins.

A photoisomerizable muscarinic antagonist. Studies of binding and of conductance relaxations in frog heart [PDF]

open access: yes, 1982
These experiments employ the photoisomerizable compound, 3,3'-bis- [alpha-(trimethylammonium)methyl]azobenzene (Bis-Q), to study the response to muscarinic agents in frog myocardium. In homogenates from the heart, trans-Bis-Q blocks the binding of [3H]-N-

Interactions between the neuromodulatory systems and the amygdala: exploratory survey using the Allen Mouse Brain Atlas. [PDF]

open access: yes, 2013
Neuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system.

Cooperative Glutamatergic and Cholinergic Mechanisms Generate Short-Term Modifications of Synaptic Effectiveness in Prepositus Hypoglossi Neurons [PDF]

open access: yes, 2005
To maintain horizontal eye position on a visual target after a saccade, extraocular motoneurons need a persistent (tonic) neural activity, called "eye-position signal," generated by prepositus hypoglossi (PH) neurons.

Deconvolution of complex G protein-coupled receptor signaling in live cells using dynamic mass redistribution measurements [PDF]

open access: yes, 2010
Label-free biosensor technology based on dynamic mass redistribution (DMR) of cellular constituents promises to translate GPCR signaling into complex optical 'fingerprints' in real time in living cells.

The effects of kindling during pregnancy on long-term potentiation (LTP) induction and M1 muscarinic acetylcholine receptors in male rat offspring

open access: yesResearch in Pharmaceutical Sciences, 2023
Background and purpose: Neonates of pregnant women with epilepsy may compromise normal neurodevelopment and hippocampal morphology. Memory and learning disorders and a decrease in verbal IQ scores are seen in these children later in life. In the previous

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 ...
