Revisiting the Endocytosis of the M2 Muscarinic Acetylcholine Receptor [PDF]

Membranes, 2015
The agonist-induced endocytosis of the muscarinic acetylcholine receptor M2 is different from that of the other members of the muscarinic receptor family. The uptake of the M2 receptor involves the adapter proteins of the β-arrestin family and the small GTPase ADP-ribosylation factor 6.

Muscarinic acetylcholine receptors of the developing retina. [PDF]

Proceedings of the National Academy of Sciences, 1977
Six- and 13-day chicken embryo retinas contain 10 and 320 fmol per mg of protein of specific binding sites for 3-[3H]quinuclidinyl benzilate, a ligand of muscarinic acetylcholine receptors. Most of the receptors of 13-day embryo retina were found, by autoradiography, to be localized in two sharp bands within the inner synaptic layer of the retina.

Endothelium‐Independent Relaxation of Alkaloid Boldine in Isolated Aortas From Normotensive and Hypertensive Rats: Participation of Ca2+ Channels

Chemistry &Biodiversity, EarlyView.
Involvement of Ca2+ channels in boldine‐induced vascular relaxation. ABSTRACT The regulation of vascular tone plays a fundamental role in blood pressure homeostasis and still represents a significant challenge in clinical practice. Boldine, a naturally occurring alkaloid from Peumus boldus, has emerged as a compound of interest due to its therapeutic ...

Population Pharmacokinetic and Exposure‐Response Analysis of the Cognitive Effects of TAK‐071 in Participants With Parkinson Disease and Cognitive Impairment

Clinical Pharmacology in Drug Development, EarlyView.
Abstract TAK‐071 is a novel muscarinic M1 positive allosteric modulator under investigation for the treatment of cognitive impairment and falls associated with Parkinson disease (PD). This study evaluated population pharmacokinetics of TAK‐071 following single (1‐160 mg) and multiple (3‐15 mg once daily) oral‐dose TAK‐071 in 112 healthy participants ...

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Perinatal Exposure to the Neonicotinoid Thiacloprid Impacts Transcription of Neuroplasticity and Neuroendocrine Markers in Mice but Not in the Zebrafish Model

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neonicotinoids are widely used insecticides in agriculture, aquaculture, pet care, and urban pest control. Initially developed to selectively target the insect cholinergic system, their extensive use has raised concerns about adverse effects on nontarget vertebrates.

Molecular properties of muscarinic acetylcholine receptors

Proceedings of the Japan Academy, Series B, 2013
Muscarinic acetylcholine receptors, which comprise five subtypes (M1-M5 receptors), are expressed in both the CNS and PNS (particularly the target organs of parasympathetic neurons). M1-M5 receptors are integral membrane proteins with seven transmembrane segments, bind with acetylcholine (ACh) in the extracellular phase, and thereafter interact with ...

Activation and allosteric modulation of a muscarinic acetylcholine receptor [PDF]

Nature, 2013
Despite recent advances in crystallography and the availability of G-protein-coupled receptor (GPCR) structures, little is known about the mechanism of their activation process, as only the β2 adrenergic receptor (β2AR) and rhodopsin have been crystallized in fully active conformations.
