Organophosphorus pesticides decrease M2 muscarinic receptor function in guinea pig airway nerves via indirect mechanisms. [PDF]
Epidemiological studies link organophosphorus pesticide (OP) exposures to asthma, and we have shown that the OPs chlorpyrifos, diazinon and parathion cause airway hyperreactivity in guinea pigs 24 hr after a single subcutaneous injection.

Muscarinic M2 acetylcholine receptor distribution in the guinea-pig gastrointestinal tract [PDF]
In the enteric nervous system, acetylcholine is the most common neurotransmitter to induce gastrointestinal smooth muscle contractions. Cholinergic signaling is mediated by muscarinic acetylcholine receptors on the surface of smooth muscle cells.

Histamine H1 Receptor Down-Regulation Mediated by M3 Muscarinic Acetylcholine Receptor Subtype
Heterologous down-regulation of histamine H1 receptor (H1R) mediated by muscarinic acetylcholine receptor subtype was investigated using five kinds of Chinese hamster ovary (CHO) cells stably co-expressing the human H1R and one of the five (M1 –M5 ...

Interaction of the Xanthine Nucleotide Binding Goα Mutant with G Protein-coupled Receptors [PDF]
We constructed a double mutant version of the α subunit of Go that was regulated by xanthine nucleotides instead of guanine nucleotides (GoαX). We investigated the interaction between GoαX and G protein-coupled receptors in vitro.

Characterization of the positive and negative inotropic effects of acetylcholine in the human myocardium [PDF]
In the human isolated myocardium, acetylcholine (10−9 to 10−3 M) elicited a biphasic inotropic effect (a decrease in the lower and an increase in the higher concentration range) in atrial and a positive inotropic effect in ventricular trabeculae. However,

Background This study determined whether changes in the expression of neuregulin (NRG) 1, erbB2 tyrosine kinase (ErbB2) and the M2 muscarinic receptor in the urothelium and detrusor muscle of the rat bladder were associated with partial bladder outlet ...

Probing the role of the cation–π interaction in the binding sites of GPCRs using unnatural amino acids [PDF]
We describe a general application of the nonsense suppression methodology for unnatural amino acid incorporation to probe drug–receptor interactions in functional G protein-coupled receptors (GPCRs), evaluating the binding sites of both the M2 muscarinic

Muscarinic cholinergic receptor (M2) plays a crucial role in the development of myopia in mice
SUMMARY Myopia is a huge public health problem worldwide, reaching the highest incidence in Asia. Identification of susceptible genes is crucial for understanding the biological basis of myopia.

RACK1 associates with muscarinic receptors and regulates M(2) receptor trafficking. [PDF]
Receptor internalization from the cell surface occurs through several mechanisms. Some of these mechanisms, such as clathrin coated pits, are well understood.
