The naked mole-rat (Heterocephalus glaber) is a promising animal model for the study of pain mechanisms, therefore a thorough characterization of this species is essential. The aim of the present study was to establish the naked mole-rat as a model for studying the cholinergic receptor system in antinociception by investigating the involvement of muscarinic, nicotinic and opioid receptors in no...
BACKGROUND It has previously been shown that deletion of chrna9, the gene encoding the alpha9 nicotinic acetylcholine receptor (nAChR) subunit, results in abnormal synaptic terminal structure. Additionally, all nAChR-mediated cochlear activity is lost, as characterized by a failure of the descending efferent system to suppress cochlear responses to sound. In an effort to characterize the molecu...

Chem. 272, 23521–23527 32 Czajkowski, C. and Karlin, A. (1995) Structure of the nicotinic receptor acetylcholine-binding site. Identification of acidic residues in the δ subunit within 0.9 nm of the α subunit-binding site disulfide....
Nicotinic acetylcholine receptors mediate fast synaptic transmission by fluxing ions across the membrane in response to neurotransmitter binding. We show here that during affinity purification of the nicotinic acetylcholine receptor from Torpedo, phosphatidic acid, but not other anionic or zwitterionic phospholipids, is hydrolyzed to diacylglycerol. The phospholipase C activity elutes with the ...
1) Nicotinic acetylcholine receptors in central nervous system are thought to be new targets for Alzheimer’s disease. However, the most involved nicotinic receptor subtype in Alzheimer’s disease is unclear. a4b2 receptor is the most widely spread subtype in brain, involving in several important aspects of cognitive and other functions. We constructed cell line by transfecting human amyloid prec...
-Philanthotoxins are noncompetitive inhibitors of the nicotinic acetylcholine receptor and the various glutamate r<.~ceptors. Analogues carrying photoaffinity labels, fluorine atoms for solid-state NMR studies of ligand/receptor interaction, and large head groups such as porphyrins and planar bulky aromatic rings (BIG analogues) for clarifying mode of entry and orientation of analogues in recep...
Nicotinic acid adenine dinucleotide phosphate represents a newly identified second messenger in T cells involved in antigen receptor-mediated calcium signalling. Its function in vivo is, however, unknown due to the lack of biocompatible inhibitors. Using a recently developed inhibitor, we explored the role of nicotinic acid adenine dinucleotide phosphate in autoreactive effector T cells during ...
Bovine adrenal chromaffin cells possess both nicotinic and muscarinic cholinergic receptors, but only nicotinic receptors have heretofore appeared to mediate Ca2+-dependent exocytosis. We have now found that muscarinic receptor stimulation in bovine adrenal chromaffin cells leads to enhanced inositol phospholipid metabolism as evidenced by the rapid (less than 1 min) formation of inositol trisp...
